Additional light performance
For TL-D lamps, using the luminaire as a ventilation point has the
additional advantage of keeping the lamp burning at the optimal
operating temperature. This means that the light output of the lamp
will increase. With TL5 lamps this advantage is not so pronounced,
although extensive tests have shown that with standard air volumes
thereissomeeffectonthelightoutput(Fw=1).Hence,light/

saving and lighting performance.
Most Philips luminaires for ceiling
systems are tted with air vents on the
top to provide natural ventilation for
the luminaire.
With a plenum box, exhaust air can be
channeled directly to an air-handling
system.
Technical data
Air–handling devices
Recessed luminaires are often installed in modular ceiling systems.
For Philips it is important that the luminaire is well integrated. It should
taestheticallyandmechanically,andthelightingperformanceshould
be optimized. The luminaire can also become an integral part of the air-
handling system. Nearly all Philips recessed luminaires have integrated
air slots and can be used effectively to handle return air.

the thermal effects and related cost savings to be calculated. Additional
