A luminaire component for use in a luminaire comprises an LED module 806 on a first printed circuit board (PCB) 808, the first PCB having a front face on which the LED module is located; a second PCB mounted forward of the front face of the first PCB, for example mounted on cylindrical collar 813, and connection means 851, 852 adapted to connect the second PCB to the first PCB. The second PCB may carry components for a wireless communication device or a sensor arrangement. Also disclosed are sensor arrangements for environmental characteristics which may be associated with bezels for luminaires where the bezel is removably attachable to the luminaire. |
