LIGHT OUTPUT DEVICE AND METHOD

摘要

A light output device includes first and second light sources, and a partly transparent mirror arranged between the light sources. The partly transparent mirror, during operation, receives substantially all light emitted by the first and second light sources, and reflects part of the light emitted by the first light source and transmits part of the light emitted by the second light source, and vice versa, such that the light from the first light source is superimposed onto the light from the second light source following reflection/transmission at the partly transparent mirror.
