A retrofit LED light source 22 for a luminaire 10â has a base 24 and LEDs (28, fig 3) mounted on the base 24 by mounting arrangements 26. The base 24 has a reservoir body 30 which provides a thermal reservoir for heat from the LEDs (28, fig 3). The source 22 has a second mount 32 for mounting the base structure 24 in a luminaire housing 12â . The second mount 32 mounts the base structure 24 in the luminaire housing 12â in place of a conventional lamp (18, fig 1) and lamp holder (16, fig 1). The second mount 32 provides thermal contact between the reservoir body 30 and the luminaire housing 12â , to cause the luminaire 10â to serve, in use, as a heatsink for heat received in the reservoir body 30 from the LEDs (28, fig 3). |
