摘要:
An illumination device or method of generating illumination using an illumination device is described with two light sources with different spectral distribution a number of displaceable light collectors collecting light from the light sources where in one mixing position receiving light from both light sources where at least one of the light sources has two independently controllable light emitting areas and in one mixing position the collecting area collects light form the first light emitting area and substantially not from the second light emitting area. Further an unrelated illumination device with at least one Light Emitting Diode, LED and a current spreader connected to and covering a first area of a first side of the lead, spreading current in an irregular pattern and a current controller controlling current flowing through the first current spreader. The current spreader can be patterned to produce a round beam illumination or illumination in a form of a static picture or logo. A round beam illumination can better cooperate with an optical system of lenses in an illumination device. Further the current spreader can be patterned to have lower current density in the center to reduce/avoid temperature hotspot in the center and obtain a more even die temperature.
