LUMINAIRE
Document Type and Number:
Japanese Patent JP2017174769
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To miniaturize.SOLUTION: A luminaire includes a plurality of light sources 18, a cutter device 5, a condensing lens 6 and an image forming lens 3. The plurality of light sources 18 are mounted on one substrate and they are arranged at a plurality of positions different from each other respectively. In the cutter device 5, an opening 8 is formed. The condensing lens 6 condenses the plurality of rays of light emitted from the plurality of light sources 18 respectively so that a spread angle in which the light which has passed the opening 8 spreads decreases. The image forming lens 3 forms an image on an image forming surface 12 with the light which has passed the opening 8 out of the light condensed by the condensing lens 6. This luminaire can decrease the diameter of the image forming lens 3 by decreasing the spread angle in which the light which has passed the opening 8 spreads, and it can be miniaturized.SELECTED DRAWING: Figure 3
