TRIOS LuxsenseLRL 1220/00 sensor, LRH 1221/00 TLD clip, LRH 1222/00 TL5 clip

Product Details• Luxsense is a light sensing

device, meant to be integratedinto the “down-lighting”luminaire, thus adding aregulating function incombination with a regulatingballast.

• Luxsense can be clicked on thelamp, using a special clip. It canalso be clicked to the endlamella of the optic, using aspecial bracket, to be providedby the luminaire manufacturer.

• Luxsense can control up to 20regulating electronic ballasts ofthe Philips HFR range.

• Luxsense can be manuallyadjusted by a rotating diafragm,in order to adjust the setpoint.

• The controller is connected tothe 1-10 Vdc control input ofthe Philips HFR ballast

Applications• Luxsense is designed to save

energy by compensating forexcess lighting levels caused by overdesign of the lightingsystem (e.g. 600 lux installed,500 lux required) and/oringressing daylight. Energysaving is realized by reducingthe output of the artificial light.

• The sensor is optimized for usein applications with 600 luxinstalled and 500 lux requiredwith an assumed reflexionfactor of the room of 30%.

• Actual circumstances may differ.To compensate for this, thesensitivity of the sensor can beadjusted manually over a rangefrom 1/3 to 3. Therefore theminimum required reflectionfactor of the room must be10% which is met by mostpractical conditions.

• Proper control operation isbased on the condition thatLuxsense controls at least 80%of the artificial light it ‘sees’. This can be critical inapplications including a highamount of indirect light fromother luminaires.

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: white/grey + ,white -.

When connected reversed 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- 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.

The setpoint of the sensor can be changed manually by using the rotary control ring on the front, which influences the diafragm. The housing is equipped with an indication of the default setting.

Note: this manual adjustment facility should preferably only be used in the commissioning phase, not by the users of the room.

A separate document is available that describes the commissioningprocess in detail. In short the steps are:• Find a room in the building that can be considered to be

representative for the whole building.• Install the luminaires with daylight control in this room and

convince yourself that the installed light level and the required light level are reasonably close to each other (within 30% range,

say 600 lux and 500 lux respectively). Light levels should be measured on the table, preferably without daylight contribution (e.g. at night).

• Manually adjust the rotary control such that the required light level is realized. Memorize the position of the control ring.

• Instruct installer to copy the position of the rotary control ring of every luminaire to be installed in comparible circumstances.

The lightsensor, LRL1220, represents a basic, straight forwardsolution to save energy. When applied with care as described inthis document, it will preform its function properly. This lightsensorshould however not be used in the following applications:• When light levels are required with a higher accuracy then

10% of the desired value. In that case, sensors and controllerswith a higher performance should be used.

• When the required light level is significantly lower than the installed level, e.g. more than 30% lower. In that case a dimming device should be installed instead.

• When the construction of the building is such that a largevariety of rooms exist, both in shape and decoration, leadingto individual fine tuning per room during commissioning. In that case, controls with optimized commissioning toolsshould be used.

The control characteristics are described in the graph. The lightsensor roughly compensates for 50% of the ingressing daylight by dimming the artificial light output, until the minimum output is reached (3% for Philips HFR)

The lightsensor can be mounted in the luminaire either by clicking on the lamp, or by fixing it to the end lamella.

Mounting on the lampThis is an option for all luminaires with a direct line of sight between the lamp and the floor of the room.The lamp clip LRH 1221 should be used in case of TLD lamps, LRH 1222 in case of TL5. The sensor can easily be clicked into the lampclip.The unit must be located:• At the (eletrical) “cold” side of the lamp. This is the side of

the lamp that is connected to the terminals of the ballast that allow for the longest wiring to the lamp. A distinct “cold side”is usually clearly marked on ballasts using the “half-bridge” principle (e.g. all Philips HF ballasts).

• As close to the end cap of the lamp as possible, but at least 7 cm away from that end cap

Please note:• It is not allowed to use lamp clips with TL5 HO (high output)

lamps, due to their high lamp surface temperatures. • Metal mirror-optics shall be properly connected to “earth”

(TLD and TL5 applications).• Mounting on the lamp is an option only for luminaires that do

not obscure the sensitivity opening angle.

Mounting on the end lamellaAs an alternative, the receiver can be mounted on the end lamella. This requires a special mounted bracket, to be provided by the luminaire manufacturer. It must be strictly avoided that the sensitivityopening angle is obscured by the optics or construction parts of the luminaire. Mounting at the (electrical) “cold side” of the lampis recommended.
