Abstract:
A light-emitting device ( 1 ) and a related light source system. The light-emitting device ( 1 ) comprises a laser light source ( 11, 21, 31 ) and a light collecting system ( 12, 22 ). The laser light source ( 11, 21, 31 ) comprises a first laser array ( 111, 211, 311 ) and a second laser array ( 112, 212, 312 ) for respectively generating a first light and a second light with different wavelength ranges. The light collecting system ( 12, 22 ) is used for collecting the light emitted from the laser light source arrays. The ratio of the divergence angle of the collected second light to that of the first light is less than or equal to a predetermined value. The predetermined value is 0.7. The light-emitting device ( 1 ) is capable of generating two kinds of light beams with different etendues.

Claim (Index 18):
A light emitting device, comprising:\n a first laser light source, for emitting first light; a second laser light source, for emitting second light, wherein the wavelength of the second light is different from that of the first light; a condenser lens, for collecting the first light and the second light, wherein the first light is disposed surrounding the second light, and the first light and the second light are parallel to an optical axis of the condenser lens; wherein the first light that is farthest away from the optical axis has a distance L 1  from the optical axis, the second light that is farthest away from the optical axis has a distance L 2  from the optical axis, and a focal length of the condenser lens is F, the ratio of arctan(L 2 /F) to arctan(L 1 /F) is less than or equal to 0.7.
