| 摘要 |
The invention concerns a lamp for uniformly lighting areas or rooms, the lamp having an electronic subassembly (3) which comprises at least three semiconductor elements or light-emitting diodes (4, 5, 6), each of which generates a luminous intensity of at least 0.2 cd and emits light in at least three different wave ranges. The subassembly (3) is equipped with an electrical circuit and power supply (14) via which the individual light-emitting diodes (4, 5, 6) can be controlled simultaneously. Lamps (1) of this type have an extremely long useful life and reduced current consumption. They are further characterized by favourable sizes even when their luminous intensity is high. |
