LIGHT OUTPUT DEVICE AND METHOD
First Claim
1. A light output device, comprising:
- a first light source;
a second light source; and
a partly transparent mirror, andcollimating means for at least partly collimating the light of the first and second light sources, such that during operation substantially all the at least partly collimated light of the first and second light sources is incident on the partly transparent mirror;
the partly transparent mirror, during operation, receiving substantially all the at least partly collimated light emitted by the first and second light sources, and reflecting part of the light emitted by the first light source and transmitting 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, wherein said collimating means comprise mirror-wise arranged portions corresponding to said first light source and said second light source, respectively, said first light source and said second light source being arranged on opposite outer ends of said collimating means.

Abstract
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.

14. A light output method, comprising:
-
at least partly collimating light emitted by a first light source and a second light source, each of said first and second light source being arranged on respective outer ends of a collimating means receiving substantially all light emitted by a first light source and a second light source by a partly transparent mirror; and reflecting part of the light emitted by the first light source and transmitting 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.
