LIGHT OUTPUT DEVICE AND METHOD

摘要

The present invention relates to a light output device (10, 50, 70), comprising: a first light source (12a, 52a, 72a); a second light source (12b, 52b, 72b); and a partly transparent mirror (16, 56, 76). The device is characterized in that 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 completely superimposed onto the light from the second light source following reflection/transmission at the partly transparent mirror. The present invention also relates to a light output method.
