Abstract (en)
The lamp has two sets of LEDs (2, 4) for emitting white light and colored light e.g. red, green or blue light, respectively. The two sets of LEDs form a light source of the lamp, where number of one of the sets of LEDs is greater than number of other set of LEDs. An optical element (10) i.e. light conductor, surrounds the latter set of LEDs such that the element optically influences the colored light. The two sets of LEDs are placed on two circuit boards (6, 8), respectively. A diffuser plate (12) is placed above the sets of LEDs, and a cover plate (14) is placed above the diffuser plate.
