A lamp module (10) comprises an LED lighting element (18) and an electronic driver circuit (42) for supplying electrical power to the LED element (18). An electrical connector (14) is connected to the electronic driver circuit (42). A bayonet coupling (16) is provided for positioning and locking the module (10) within a reflector (70). A metallic heat sink (30) with a top wall (34a, 34b, 34c) and a side wall (36a, 36b, 36c) has an inner cavity (40), where the electronic driver circuit (42) is located. The LED element (18) is located at the top wall (34)a in direct thermal contact to the heat sink (30). A lighting unit comprises the above-described lamp module (10) and a reflector (70) with a mounting cavity (74). The module (10) is mounted within the cavity (74), so that the light emitted from the LED (18) is reflected by a reflector surface (72) of the reflector (70). |
