As in recent years, the dominant application for high-brightness (HB)LEDs in 2005 was mobile appliances (figure 1). This category includesboth mobile phones and other portable electronic products, such asdigital cameras, PDAs, MP3 players and hand-held game players.
Although mobile appliances accounted for more than half of thetotal market of $4.0 billion in 2005, this represented a lower marketshare than in 2004 (all market figures relate to sales of packaged HB-LED devices). During last year the use of HB-LEDs for display andkeypad backlights began to saturate, and prices declined dramatically,especially for keypad backlights, owing to excess production capac-ity in Asia.
In spite of the stagnation of the mobile appliance market in 2005,other applications continued along the growth path of recent years,with overall growth of all applications other than mobile appliancesestimated at 21%. This growth was led by the illumination category,which grew by more than 40%.
In the next five years the growth rates among the various applica-tions will differ dramatically, so the application break-out in 2010 willlook quite different from that in 2005 (figure 2).
In 2010 the contribution from mobile appliances will decline to just28%. Overall this market is expected to remain flat. The market forHB-LEDs in mobile phones is in fact forecast to decline substantially,owing to saturation, price declines and the increasing penetration ofOLED displays.
However, the use of white LEDs for backlighting small full-colorLCD displays in digital cameras, MP3 players and hand-held gameplayers – all of which are experiencing rapid unit growth – will helpto sustain the market. In addition, white LED backlights for notebookcomputers, which first began to appear in 2005, will make a sub-stantial contribution.
The most significant changes in market share will be in the signs/dis-plays and illumination categories. The signs/displays category includes
not only large LED text messaging and full-color video screens butalso LED backlights for LCD monitors and TVs.
While this latter application was just in its beginning stages in 2005,rapid growth is expected in the next five years, with even modest pen-etration of the large projected LCD monitor and TV markets (more

than 180 million monitors and more than 90 million TVs) making asignificant impact on the HB-LED market in 2010.
Penetration of the general lighting market is the “Holy Grail” of theHB-LED industry, and by 2010 this penetration will be well under way.Although most of the lighting applications being addressed in 2010will continue to be specialty or niche applications, many of them forcolored lighting, there will also be a growing number of white-lightapplications in the retail display, commercial building and even resi-dential markets. These will be driven by continuing improvements inwhite LED luminous efficacy (lumens/watt), as well as concomitantdecreases in dollars per lumen and the development of user-friendlyintegrated LED luminaires.
Although the market share for automotive applications (includingboth interior and exterior lighting) does not show an increase from2005 to 2010, large market growth will still take place. To a large extentthis will be driven by the use of white LEDs for headlamps, which areexpected to enter the market for the first time in late 2007.
As figure 3 shows, the 2005 HB-LED market continued to be dom-inated by products that use standard LED packages – either traditionallamp packages (e.g. 3 mm, 5 mm) or various SMD configurations (e.g.topview, sideview, PLCC). Standard packages are widely use in mobilephones, LED text messaging and full-color video screens, automo-tive interior lighting, and some specialty lighting applications.
High-current LEDs (i.e. those that have drive currents that are muchhigher than the standard 20 mA) are used primarily in automotive sig-naling, but also in various illumination applications, such as channelletters and machine vision. Multichip packages, typically consistingof one red, one green and one blue chip in the same package to achievemultiple colors, are used mainly in ringer lights for mobile phones,but increasingly in small-pitch (<10 mm) full-color video screens.
The fastest-growing product type in the next five years will be high-power LEDs. These have input powers in the 0.5–5 W range and out-puts ranging from tens of lumens to more than 100 lm. These devicesuse large-area chips and special packaging for thermal management.Their largest use currently is in illumination applications, with sig-nificant use also in traffic signals and flashlamps for camera phones.In addition to illumination, major future growth areas will be in back-lights for LCD monitors and TVs, and automotive forward lighting.

Rapid innovations and developments in the lighting industry, coupledwith the importance of energy savings and environmental friendli-ness, have encouraged the lighting industry to look for an alterna-tive for the basic light source, which has been around for more than100 years – the incandescent bulb.
Solid-state lighting (SSL) has nothing in common with the bulbother than the purpose of illumination. Even though solid-state tech-nology has been around for more than four decades, extensive researchand innovations in the last few years have unveiled SSL’s true poten-tial and its ability to change the landscape of the lighting industry.
The low efficiency of existing light sources, combined with theirlimitations in design, drive the need for an innovative solution, andSSL is emerging as a viable option. However, more improvement onthe levels of light output and color quality, along with a reduction inthe initial cost, are necessary to enable it to make a significant impacton the lighting industry.
LEDs are already being used in applications where upfront cost isnot the major issue, such as traffic signal lights and camera flashes.
Organic LEDs (OLEDs) are a new breed of SSL, combining someof the performance characteristics of LEDs with additional features,such as thinness, transparency and flexibility. Further, OLED tech-nology opens up the possibility of many innovative new applications,such as a dual functional window, which remains transparent in thedaytime and functions as a light source at night.
OLEDs have already demonstrated commercial feasibility via theintroduction of products for flat-panel displays in mobile applications.The intrinsic features and strong potential of OLEDs – thin mod-ules, large illumination areas and low power consumption, among oth-ers – make this technology a prime candidate for future lightingapplications. However, there are some challenges yet to be addressed,such as moisture sensitivity and outcoupling (figure 4).
The LED industry, with its promising future and fierce market com-petition, has been showing tremendous progress in recent years. Someof the key challenges that have to be addressed are high cost, patent-infringement issues and thermal management (figure 5).
The research focus on OLED and LED technologies is likely to shifttoward factors such as new materials and production techniques, whichwill contribute to reduced costs. One of the major drivers for SSLR&Dis the immense investments by both government and corporate bod-ies, such as the Next-Generation Lighting Initiative (NGLI) in the US,Europe’s Organic LEDs for ICT and Lighting Applications (OLLA)and Japan’s Light for the 21st Century project.
The LED industry is focused on the development of more compact
Solid-statelighting presentschallenges forLED and OLEDtechnologiesSolid-state lighting is a viable option for thelighting industry, but there are a number ofhurdles that need to be overcome, accordingto Ashwini Meena of Frost & Sullivan.

Originally introduced as simple indicator lights, the more recent dis-covery and emergence of high-brightness LEDs has taken the indus-try by storm. They are now expected to gain even greater market sharein a number of different application segments.
Although their use spreads across a variety of segments and appli-cations, for the purposes of this analysis we have studied signaling,signage, illumination and automotive. The latter segment includesonly signaling, tail-lamps and headlamps.
Each of these applications uses drivers to provide the power neededfor the LEDs. The forecasts are for the number of drivers, not LEDs,because each application can incorporate hundreds of emitters.
Figure 6 shows shipments of LED drivers according to power sup-plied. The >15 W segment is largely driven by signage applicationsLarge-format scrolling and animated LED signs have recently emergedthat can consume upwards of several hundred watts of power. The>15 W segment is the largest, with driver sales of 157.4 million units
in 2005. Shipments will grow at an annual average rate of 14.1%,reaching 303.9 million units by 2010.
Most signaling applications fall within the 6–15 W segment. Theseare largely responsible for shipments of 14.1 million units in 2005.
Meanwhile the <6 W segment consists of a variety of uses, rangingfrom certain automotive applications to exit signs. This segment isforecast to grow at an average annual rate of 18.2%, from sales of40.8 million units in 2005 to 94.4 million units in 2010.
Two major hurdles standing before widespread adoption of LEDsare lumens and price. Before LEDs can be used in many applications,the technology must produce light that is bright enough to merit its
Demand for LED drivers will grow at anaverage annual rate of almost 15%,according to Linnea Brush of Darnell Group.

The use of HB-LEDs for automotive applications is currently a veryhot research and development topic, with the objective of decreas-ing price while increasing performance. LEDs have very strong mar-ket opportunities in the automobile as they can be used for front andrear lighting, as well as for interior lighting.
For automotive applications the main advantages of LEDs are:● they are environmentally friendly, containing no mercury andhaving low power consumption;● they have a long lifetime of 10 000 h compared with the 3000 hminimum expected lifetime for incandescent bulbs;● they bring improved safety: they have a fast reaction time andlight up around 250 ms quicker than incandescent bulbs (at a speedof 100 km/h, that represents a gain of 7 m in braking distance).
LEDs can be used for both internal and external lighting. The HB-LED market for interior lighting is the largest of the two segments,while the external lighting segment will have the highest growth rate.Figure 7 shows the 2009 market forecast for LEDs in cars, which willhave a total value of $800 million.
External lighting will represent 40% of the total for automotiveapplications in 2009, or well in excess of $300 million. The externalLED lighting market will grow by 72% between 2003 and 2009,mainly driven by the introduction of white HB-LEDs for forward light-ing. In contrast, the HB-LED market for interior lighting will haveonly a 5% growth rate.
The market for LEDs in front lighting is just beginning. Althoughthe first LED-based front lights (specifically LED-based daytime run-ning lights) appeared in 2004 on high-end cars, the market will reallytake off in 2008.
There are, of course, some drawbacks to the use of LEDs for exter-nal lighting. First, regulations must be updated, particularly in Europe,to allow LEDs to be used in all external applications, including frontlighting. Second, the cost in lumens per dollar is still too high. Figure8 shows the current best commercially available performances andprices for HB-LEDs, together with the cost objective that would per-mit widespread use throughout the automotive market. The cost objec-tive for automotive is likely to be reached in 2010–2012, and by thistime LEDs will be the dominant light source for external lighting.
Despite the difficulties, many players have announced prototypes
and preseries for front lighting based on white HB-LEDs. To name afew: Audi has announced that the Audi A8 will have LED-based frontlight with luminous performances competing with xenon in 2008;Hella is collaborating with Volkswagen to commercialize an LED-based front lighting system with a 1000 lm output in 2008; and, in theUS, Visteon and General Motors have disclosed that they are devel-oping LED-based lighting.

The rapid rate at which LEDs have enteredand become ubiquitous in lighting has pre-sented industry, R&D and regulatory bod-ies with several measurement challenges.LEDs are already replacing incandescentlighting in many scenarios and are cur-rently being developed for specializedapplications such as combined brake andindicator lights in the automotive industry.They are also being used in more safety-critical areas, including railway signallingand medical phototherapy.
LEDs now come in a variety of wave-lengths (UV through the visible to IR),brightness values (e.g. 140 lm flux from asingle green LED produced by Lumileds)and formats (single packaged LEDs; multiple LEDs in clusters; andeven novel technology including LED backlights and organic LEDs).It has been shown that differences in inter-industry measurements arestill large, yet it is necessary to measure LEDs in a precise, accurate,well defined and, we would say, traceable manner.
In many cases, manufacturers rely on customer feedback to revealthe failings of LED products. Better measurement will produce bet-ter LEDs more efficiently, and lumens per dollar is a standard thatindustry understands.
Quality measurement is also driven by safety, covering areas suchas conspicuity of signalling lamps and photobiological hazards ofhigh-brightness LEDs. This area also includes the need to conform tointernational regulations and standards, an effort to which the UK’sNational Physical Laboratory (NPL) is currently contributing.
Optical radiation measurementThe measurement of the optical radiation characteristics of LEDs canbe divided into four interrelated categories: photometry, radiometry,and spectral and angular distribution. Measurements are needed forproduct development and quality control, to enable comparisons tobe made between products, and for specification and safety purposes.Traceability to national standards (such as those developed and main-tained at NPL) is also important, because this helps to ensure consis-tency and gives the market confidence in the claims that manufacturers’make for their products.
PhotometryPhotometry is the measurement of lightweighted by the response of the human eye(i.e. it measures the ability to generate avisual response). As many LED productsare made to been seen by people, it is per-haps the most important measurement.However, it is also often the area with thegreatest measurement error. These errorshave three main causes: spectral mismatcherrors in the photometric detectors; prob-lems with geometric alignment; and tem-perature dependence of the luminous andspectral output of the LED.
To measure a photometric quantity, thedetector used – a photometer – must have
a spectral responsivity that is matched to the visual response of thehuman eye. Photometers generally incorporate optical filters such thatthe transmission of the filter and the spectral response of the detec-tor work in combination to match the response of the eye closely.However, no photometer can be perfectly matched to this function,with the result that errors occur when one is used to measure a lightsource that is different from the source against which it has been cal-ibrated. These errors can be very large – errors of tens of percent arecommon. Appropriate calibration of the photometer can minimize theerrors but, for work of the highest accuracy, a spectroradiometer isgenerally recommended, which measures the light energy at individ-ual wavelengths so that the photometric quantities can be calculatedusing the defined weighting functions.
The novel construction and packaging of LEDs also create specialdifficulties in measuring their light output, because they lead to highlydirectional and non-uniform light-distribution patterns. Furthermore,the mechanical and optical axes may not be coincident, which canlead to inconsistencies between different measurement systems – aproblem that is compounded in LED clusters. Correct geometricalalignment is therefore important if consistent and reproducible meas-urements are to be made. The CIE, for example, recommends that, forsingle LEDs, the mechanical axis rather than the optical axis shouldbe taken as the reference for measurements of luminous intensity orilluminance. Geometric alignment is less critical for measurementsof the total luminous flux (i.e. the total light output in all directions,

The bright & creative ideas of lighting architects would often dim & fail in the past because of technical difficulties or commercial constraints.
LEDs now make it possible to create a whole new world of lighting. They also provide much more effective lighting than conventional sources while consuming much less energy. All of this, and a service life of 100,000 hours. However, to get the best from LEDs, you need the right partner with the appropriate expertise and the ideal product range. This is where EBV excels. With more than 40% market share, EBV Elektronik is easily the leading specialist for optoelectronics technology in European semiconductor distribution. EBV‘s dominance of this segment is further underpinned by awards such as “European Distributor of the Year”, presented by OSRAM Opto Semiconductors in 2004 & 2005. Our experienced application experts, who concentrate solely on the use of LED technology in lighting, will offer you full support in turning your ideas into reality.

usually measured using an integrating sphere), but this is a less use-ful parameter for comparing the “brightness” of one LED with that ofanother.
As semiconductor devices, LEDs are temperature sensitive. As aconsequence a change in temperature, produced by current heating orambient temperature, can change the spectral distribution and inten-sity of the LED emission. It is therefore recommended that LEDsare temperature stabilized and operated at constant current.
RadiometryRadiometry refers to measurement of all optical radiation, whetherinfrared, visible or ultraviolet, either in terms of the total powersummed over all wavelengths at which the LED emits, or as a func-tion of wavelength. The basic unit reported for IR and UV LEDs isusually radiant power in watts, which is the spectrally integrated value.The primary measurement method is to use an integrating sphere,where all of the light emitted from the LED in all directions is meas-ured. The same precautions used for measuring LEDs photometricallyshould also be followed when making radiometric measurements.
Spatial characteristicsManufacturers produce LEDs with different spatial characteristics,butseldom state the degree of asymmetry of the light distribution patternor the change in output as a function of angle. It is often assumedthat the radiation pattern of circular LEDs is both Gaussian and sym-metric, yet this is often not the case. Knowledge of the angular depen-dence is necessary for a range of applications, including displays andtraffic signals. A traffic-light, for example, requires a narrow angu-lar distribution (so that the signal does not confuse drivers approach-ing a junction from other directions), whereas a display requires a widedistribution so that it can be seen from almost any angle.
The spatial distribution of an LED can be characterized using agoniometer, and measurements are made either by moving the detec-tor around the sample or by tilting the LED. NPL has many integrat-ing spheres and goniophotometers, and the one chosen for a particularmeasurement depends on the size and power of the light. The refer-ence goniophotometer (figure 1) has a maximum detector to sourcedistance of 15 m, which can permit very high angular resolution oflarge sources, such as luminaires and spotlights.
StandardsDifficulties in the measurement of LEDs have been highlighted bydiscrepancies in the measurement results between different laborator-ies. Different instruments measure different optical radiation charac-teristics with varying degrees of success. Many offer precision, butnot all deliver the measurement accuracy required.
At present there are few standards, and performance varies fromone measurement facility to another. However, help is at hand. TheCommission Internationale de L’Eclarage (CIE), the internationalcommission on illumination, has been establishing guidelines for mea-suring LEDs since 1997. Teresa Goodman at NPLis currently the divi-sion director of CIE Division 2, which covers the physicalmeasurement of light and radiation. The latest progress of the varioustechnical committees (TCs) is described below (for more details ofthe committees, see the CIE Division 2 website at http://cie2.nist.gov):
TC2-45 is concerned with the measurement of single LEDs. Theaim is to revise CIE 127 (see “Standardization of LED measurements”
LEDs Magazine – see Links box)to include improved definitionsof quantities and methods of mea-surement for total flux and partialflux of LEDs and to reevaluateother parts, including spectral andcolor measurements of LEDs.The measurement issues dis-cussed above are detailed, withparticular reference to the mea-surement of luminous flux, whichis important in lighting and sig-naling applications.
The preparation of an interna-tional CIE/ISO (International
Standards Organisation) standard on the measurement the luminousintensity of LEDs is being carried out by TC2-46. This will supportdevelopment and trade, but compliance with its recommendations willpresent a challenge to manufacturers.
The special problems associated with measurements of LED clus-ters and arrays are being addressed by TC2-50. The efforts of thisTC are being supported by the work of a focused interest group formedwithin the Optical Radiation Measurement Club (a measurementforum run by NPL), which has been studying the measurement issuessurrounding LED clusters and will report its findings shortly in a best-practice guide report (see http://www.npl.co.uk/optical_radiation/orm-club/fig/#led%20clusters%20wg).
SafetyRecent significant advances in the brightness of LEDs and the intro-duction of devices emitting at shorter wavelengths has led to increas-ing concern regarding the photobiological safety of LED products.High-brightness LEDs are being incorporated into lighting productssuch as traffic-lights, torches and car headlamps, which may be shonedirectly into people’s eyes. Confirming the photobiological safetyof such products is obviously extremely important.
From a photobiological safety standpoint, the spectral characteris-tics, radiance (“brightness”) and apparent source size of the LED

“Confirming thephotobiologicalsafety ofproducts thatmay be shonedirectly intopeople’s eyes isobviouslyextremelyimportant.”
are all important. Apparent source size dictates the size of the lightpatch on the retina after it has travelled through the light focussingparts of the eye. In safety standards, LEDs have been treated both aslasers (IEC 60825 series) and as lamps (CIE S 009/E:2002“Photobiological safety of lamps and lamp systems”). This has causedsome confusion relating to the risk on the part of both customers and,more important, manufacturers. Measurement errors add to the con-fusion because LED sources often incorporate some form of lens, andthis means that the “apparent source size” (“optical size”) is not thesame as the physical size of the LED chip (“die”).
Both of the standards for LEDs (see above) require a considerationof the apparent source size. NPL has carried out research for the UKHealth and Safety Executive to develop a method of measuring appar-ent source size (see Links box) and the facility for its measurementis shown in figure 2.
If, as expected, LEDs are removed from IEC 60825-1 and movedto CIE S 009 (which has been submitted to the IEC to allow it tobecome a joint IEC/CIE standard), it will make the issue of LED safetyclearer. This will also have an impact on compliance for Europeanconformity CE marking, though it must be noted that this has oftennot been rigorously followed by manufacturers.
Also on the horizon is the EC physical agents (optical radiation)directive “on the minimum health and safety requirements regard-ing the exposure of workers to the risks arising from physical agents(optical radiation)”. This “sunshine directive” deals with risks arisingfrom exposure to optical radiation and may have an impact on someLED applications. It is set to be incorporated into European law by2010 and will perhaps benefit from the clarification of LED safetyrequirements discussed above, but those responsible for its enforce-ment will need to keep pace with ongoing developments of LEDs.

SmartGels serve as encapsulants for high-brightness LEDs. They are designed to increaselumen output, extend lumen life and survivedemanding operating conditions. Unlike opticalepoxies, SmartGels provide a pliable connectionbetween rigid parts, taking up the differentialthermal expansion without inducing excessivestresses or delamination. They are “crystal clear”throughout visible wavelength, with a typical opticalabsorption of <0.001%/µm. They’re manufactured,filtered and deaerated in a clean- roomenvironment to ensure they are free from light-absorbing microscopic particulates.
SmartGels are “taught” how to work in your LEDsand adapt to your production environment:● the refractive index of the gel is matched to therefractive index of your lens; ● the cured consistency is matched to your specs,from gelatin-like with self-healing characteristics tohard silicone rubber; ● the pot life is set to meet your productionrequirements – from a few minutes to many hours.
SmartGels can also be formulated to resist water,ionizing radiation, reactive chemicals, yellowing atsoldering temperatures and more. Every SmartGelis designed for reliability and long service life.

Ocean Optics offers an LED-measurement systemfor determining absolute spectral intensity values(in watts, joules, lumens or candela), colorparameters (including X, Y, Z and L*, a*, b*) andfeatures such as dominant wavelength, peakwavelength, centroid and FWHM. Designers andmanufacturers of LEDs use the system to ensureconsistency in spectral output and color.
At the heart of each LED measurement system isa miniature fiber-optic spectrometer that the usercalibrates with a NIST-traceable light source. Userscan configure complete systems by simply addingan integrating sphere to collect light from the LED,optical fiber to carry the light to the spectrometer, aNIST-traceable power supply to adjust and displaythe power supply drive current, and software tomake sense of it all. Because all of the LED systemcomponents are modular, users are not limited toone set of operating parameters and can easilyoptimize a system for their application.
