Abstract

A luminaire component for use in a luminaire, said component comprising:

• • (i) an LED module on a first printed circuit board (PCB), the first PCB having a front face on which the LED module is located;
  • (ii) a second PCB mounted forward of the front face of the first PCB;
  • (iii) connection means adapted to connect the second PCB to the first PCB.

The invention also extends to a luminaire bezel containing one or more sensors, where the bezel is removably attachable to the luminaire. The sensor(s) can measure one or more environmental characteristics and electrical and signal contacts between the bezel and the luminaire are provided. Preferably the electrical and signal contact means is cableless.
