Lux Sense

Luxsense - DLR optionLRL 1220/00 sensor, LRH 1221/00 TLD clip, LRH 1222/00 TL5 clip, LRL 1220/08, LRL 1220/05

Description• Luxsense is a DayLight Regulation option

(DLR) for luminaires equipped with aPhilips HFR ballast. The sensor measuresthe reflected light coming from thesurface below. It dims down the lampoutput when the light level exceeds therequired light level defined by the lightsensor setpoint.

• Luxsense can be installed in the luminaireeither clicked to the lamp with a lampclip or clicked to the end lamella of theoptic with a bracket.

• Luxsense is available:- as separate components: LRL1220/00

sensor, LRH1221/00 TLD lamp clipand LRH 1222/00 lamp clip

- as a complete set with a sensor and alamp clip: LRL 1220/08 for TLD lampsand LRL 1220/05 for T5 lamps.

Features• Luxsense is connected to the 1-10Vdc

control input of the HFR ballast.• Luxsense dims light down to the mini-

mum level of the ballast (3% for thePhilips HFR ballast)

• Luxsense is calibrated for use in astandard office situation with 600 luxinstalled and 500 lux required.

• If needed, Luxsense can be manuallyadjusted by a rotating diaphragma toadjust the setpoint. The sensitivity of thesensor can be changed within a rangefrom 1/3 to 3.

• The new setpoint can be copied for allluxsense luminaires with similar daylightand reflections conditions

• Luxsense can regulate up to 20 luminairesequipped with Philips HFR ballasts

Application• Luxsense is meant to save energy by

reducing excessive light due to:- over design (e.g. 600 lux installed and

500 lux required)- daylight ingress (see savings potential

below)

• Energy savings potential is 35% onaverage:± 10% (window/corridor side)± 5% (summer/winter season)± 5% (south/north side)

Energy saving potential of Luxsense depending on location and season

Assumptions: 600 lux installed, 500 luxrequired, average European officebuilding, luminaire position on 1m resp3,5m from the window, compared to anequivalent installation with electronic nondimmable ballast (HFP).

• Luxsense is designed for average ceilingheights of 2.5 to 3 m.

• Luxsense can be used alone or incombination with other controlsproducts in order to add the daylightregulation functionality. (e.g.: combinationof Luxsense with Occuswitch).

Technical dataEnvironmental conditionsOperation conditions

Ambient temperature 5°C to 55°CRel. humidity 15% to 90%, no condensationMax. temperature of clip to lamp contact surface 70°C

Storage conditionsAmbient temperature -25°C to 70°CRel. humidity 5% to 95% at 25°C

Safety When connected to the control input of a Philips HFR ballast, the sensor has double isolation to mains connected parts.

Connection 2x0,5mm2, flying leads, length 700mm.

Colour coding of cable: white/grey + ,white –. When connected wrongly to the ballast dim input, the ballast input is short circuited, resulting in minimum light output.

Housing material ASAcolour light grey (similar to RAL 7035)

Weight/dimensions Approx. 20 grams, 25x21x19mm.EMC According to IEC 1547/EN 50082-1Control signal input - operating voltage: +1,5 - +10Vdc

- operating current sink 100µA-3mA(sufficient for 20 Philips HFR ballasts)- control voltage variation: < 0,5V

over current and temp.range- default setting: 5Vdc at 37,5 lux/

140µA (factory calibration tool)- step response: within 2 sec. on 5V

after power-up in case of insufficient ambient light

- max. input voltage (maximum rating): 15 Vdc

- max. current sink(maximum rating): 50 mA

Optical characteristics - It is assumed that the reflection in a room is such that a light level of 500 lux on a table (0,8 mtr in height) will result in 25 lux seen by the controller at ceiling height (2.5 mtr) under a viewing angle of 45°

- The opening angle can be adapted by the diafragm control, realizing an attenuation factor between 1/3 and 3.

Controls characteristics Luxsense compensates approximately for 50% of the added light (simulated and measured with a fluorescent light source). See graph below. In case of a natural light source, the compensation is higher than 50%.

Luxsense controls characteristics

Please note that luxsense is not designed for maintaining a constant lightlevel.

Installation

Mount the luminaire withLuxsense DLR option.

Measure the lux level under the light sensor (with no ornegligible daylight contribution).

If needed, turn the diaphragmuntil the required light level isreached (with no or negligibledaylight contribution).

Manual adjustment of the lightsensor.

Copy the new setpoint in otherrooms in case of similar daylightand reflection conditions belowthe sensor.

Warning: the required light level should be no more than 30% lowerthan the average installed light level, without daylight contribution (e.g. 625 lux installed, adjustment down to 430 lux is possible).

Installation warning

Throughlooping luxsense Master luminaire (M) to slave luminaire (S)• Up to 19 slave luminaires can be looped through to 1 Master

luminaire if all luminaires are equipped with Philips HFR ballasts.• Slave luminaires should have similar daylight conditions to the Master

luminaire

• Through looping shall be done by connecting 1-10V “+ to +” and ”– to –“

• Through looping of luminaires shall only be done within the samedistribution circuit

• Never loop through 2 Master luminaires!

Installation of luxsense into the luminaire

Connecting diagramme of the sensor to the ballast

• the maximum temperature ta should always remain below 70 ˚C• the sensitivity opening angle should never be obscured by the optics

or any other part of the luminaire• metal optics shall be properly connected to “earth”

Luxsense can be fixed in the luminaire either with a lamp clip or aspecial lamella bracket.

a. Mounting on the lamp

Luxsense mounted with a lamp clip

• Only for TLD and T5 lamps• Never with High output lamps

• Luxsense shall be positioned 7 cm way from the end cap on the(electrical) “cold” side of the TL lamp. This is the side of the lampthat is connected to the terminals of the ballast that allows for thelongest wiring to the lamp.

b. Mounting on the end lamella

Luxsense mounted with an end lamella brachet

• As an alternative, the sensor can be mounted to the end lamella with a special bracket provided by the luminaire manufacturer.

• The lamella bracket shall be designed in such a way that ta<70˚C.• It is recommended to mount the sensor 7 cm away from the end

cap on the (electrical) “cold” side of the TL lamp.
