The range has been designed to match Zhaga 24 mm di-mensions with three available lengths: 140 mm, 280 mm and 560 mm. By offering identical distance between LED packages on the modules, you can build linear luminaires of various lengths, starting from 140 mm up to many me-ters in 140 mm intervals just by assembling the modules in line.

LS Series is available in 3000 K and 4000 K colour tem-peratures. The modules have been specifically designed to match with Helvar’s latest low-current LED drivers while connected in series.

1.1 About this guide

1.2 LS Series – modular construction

This guide has been prepared to help the luminaire designers and manufacturers in the process of designing Helvar LS Series modules into the luminaires and also to give mechanical and electrical guidelines for the luminaire assembly.

LS Series offers modules with three available lengths: 140 mm, 280 mm and 560 mm. By offering identical distance between LED packages on the modules, you can build linear luminaires of various lengths for different applications, just by assembling the modules in line.

LS Series modules are designed to be easily connected in series.

Because of accurate regulation of single LED packages in Helvar modules, par-allel connection is also possible, though not recommended.

Do not, however, connect modules of different lenghts in parallel with each other!

4 LED MODULE SYSTEM DESIGN

LIMITATION OF LIABILITY. ALWAYS CHECK AND FOLLOW EXACT REGULATIONS FROM LATEST RELEVANT IEC/EN STANDARDS.

4.1 Electrical design, electrical safety

During the design it is luminaire manufacturer’s responsibility to follow the international and national electrical design regulations and recommendations for the electrical safety and luminaire protection. Electrical safety classification and protection class is depending on:

1. Actual luminaire design and safety classification

• According to standard IEC / EN 60598-1

2. LED driver insulation between live parts and touchable parts

• Basic insulation for Class I luminaire constructions or double insulation for Class II luminaire constructions. For Class I constructions, all accessible conductive parts that are insulated only by basic insulation, must be properly connected to protective earth.

3. LED driver output isolation (galvanic isolation)

• When SELV < 60 V, SELV poles can be accessible

• When SELV < 120 V, the SELV conductors must be insulated from accidental contact

• When non-SELV, all live parts, including conductors, must be properly insulated from accidental contact

4.2 Terminology

ELV, EXTRA LOW VOLTAGE• Voltage which does not exceed 50 V AC RMS or 120 V ripple free DC between conductors or between any conductor

and earth

SELV, SAFETY EXTRA LOW VOLTAGE• ELV in a circuit which is isolated from the mains supply by insulation not less than that between the primary and

secondary circuits of a safety isolating transformer

4.3 Touch protection

When using other than SELV drivers in the luminaire, the accessible conducting parts of the LED modules must be pro-tected from accidental touch. This can be done easily with slim Helvar LMC protective covers and mounting parts. Opal and matt opal LMC covers offer also diffusion to improve the uniformity of the light output and decrease the glare. More detailed information, datasheet and installation guide can be found on LMC product website in www.helvar.com.

O27 002 1 A




4.4 Construction of CLASS I luminaireLuminaires with:

1) basic insulation between live electrical parts and accessible parts of the luminaire body and

2) protective earth.

Electrically conductive casing components are connected via a protective conductor system which is at earth potential. Protective earth (PE) conducts in such a way that touchable parts can’t become live in case of the basic insulation fails. These luminaires are classified as Class I.

Note: Class I luminaires can have Class II or Class III parts!

4.5 Construction of CLASS II luminaireLuminaires with no protective earth conductor and where the accessible parts of the luminaire are separated from the live parts by double or reinforced insulation.

Note: Class II luminaires can have Class III parts!

5.1 LEDesign™

To ease up the driver selection Helvar has developed the LEDesign™ calculating tool to assist LED specialists inselecting the appropriate control gear for LED light sources. Based on the chosen LED modules, whether Helvar LED modules or then custom ones, LEDesign™ will automatically recommend Helvar’s compatible drivers for that load. The LEDesign™ calculator is free to use and available on the Helvar website as online web version, downloadable Windows PC executable and Android/iOS application, just go to ledesign.helvar.com/

5.2 Controlling LED module solutions

The high quality dimmable DALI drivers ensure reliable and smooth dimming of the LED modules. Helvar’s LED drivers are complemented by a full and compatible range of Helvar controls and sensor solutions, suitable for both luminaire based or standalone applications (easySwitch™, iDim smart solutions) and networked applications (DIGIDIM, Imagine). For more information please visit www.helvar.com/en/solutions/

5 SUPPORT & INFORMATION

4.6 Construction of CLASS III (SELV) luminaireWith luminaires or luminaire parts in protection class III (SELV), the protection against electric shock relies on supply at safety extra-low voltage (SELV). When such part is combined with Class I or Class II driver, the protection class of the combination is according to the driver.• Only LED drivers providing SELV output in independent use / remote installation• If LED module is accessible and SELV output poles touchable, driver must be SELV < 60 Vdc• If the conductors are insulated, driver can be SELV <120 Vdc

6 LED MODULE GLOSSARY

CCT Correlated colour temperature, corresponds to the temperature at which an ideal black body radiator would emit that kind of light. Rated in Kelvins, low CCT light is seen as warm and high CCT light is seen as cold.

COB Chip on Board LED module, the actual light source of the luminaire, with small and often round-shaped light-emitting surface. Suitable for example tracklights, spotlights and downlights.

Forward voltage The voltage over one LED package or the whole LED module. Varies depending on the temperature and forward current flowing through the chips. The output voltage of LED driver is equal to the forward voltage of the connected LED module set.

LED Driver The power supply unit for the luminaire which is selected within the electrical parameters matching the LED module(s). Helvar constant current LED driver range features not only selectable drive currents but also adjustable currents for fine tuning the lumen output of the luminaire as well as DALI control, dimming capability and smart functionalities such as self- learning.

Heat sink Heat sink dissipates the excess thermal energy away from the LED module. Heat sinks are mainly used with COB modules and they are closely related with the operating conditions of COB, which may have influence on the degradation of luminous performance of the module. It is thus very important to design an optimum heat sink attached to the COB to achieve a good heat dissipation.

Luminous efficacy Measured in lm/W. Luminous efficacy tells how efficiently input power in converted to output visible light, measured in lumens.

Luminous flux Measured in lumens. Luminous flux tells how much electromagnetic radiation in the visible light spectrum, weighted by human eye sensitivity function, is emitted by the light source in all directions combined.

L70B50 Lifetime expectancy. E.g. L70B50 at 50 000 hrs means that no more than 50% (B) of the LEDs are likely to fail at producing at least 70% (L) of the initial light output after 50 000 hours of use.

Beam angle I.e. half beam angle, the angle in which the luminous intensity has reached half of the maximum value.

MacAdam/SDCM Measurement of the colour conformity of the light emitted by the chips in the module, scale is steps (e.g. 3-step MacAdam, or SDCM = Standard Deviation Colour Matching). The exact colour coordinates of the light emitted by all manufactured modules with that model and certain CCT shall then be inside a certain ellipse around the specified x,y colour coordinate spot. The less steps, the smaller is the ellipse and tighter the conformity.

Tc Case temperature (Tc) point can be found on the module, it is usually a metallic spot marked with the text “tc”. Module performance specifications and lifetime estimations are made in certain Tc temperature values in this point.

Tp Performance temperature (Tp) is the temperature in specific point, where the performance of the module is specified. In Helvar modules, Tp is a certain Tc temperature in the Tc point on the module.
