A wall-mounted light fitting or floor-standing light 1 is arranged with a single forward-facing internally illuminated panel 6 or block, and with one or more light projector units which illuminate a wall behind it 2-5. This panel and each of the rearward light projection units make use of light-producing components (e.g. red, green, and blue LEDS) which combine and mixed in such a way that they are perceived by the human eye as being any of a wide range of colours. An arrangement of cooling fins (7, Figure 14) is used in such a floor-standing or wall-mounted light to disperse the heat generated by powerful LEDs. These cooling fins are placed between an internally-illuminated block at the front of the light, and a set of one or more rearward-projecting banks of coloured LEDs, at the back of the light. |
