Title:
DEVICE AND METHOD FOR RADIATING LIGHT BEAM IN ORDER TO FORMING IMAGE, PROJECTION SYSTEM, AND DISPLAY USING THE DEVICE
Document Type and Number:
Japanese Patent JP2019008296
Kind Code:
A
Abstract:
To provide a device capable of greatly reducing light intensity to adapt light intensity of a beam to both of a daytime operation state and a nighttime operation state.SOLUTION: A device for emitting a light beam (10) in order to form an image, comprises one or more light sources (4, 5, 6) respectively configured to emit laser beam (7, 8, 9). The device is configured to form the light beam (10) with one laser beam or by combining and converging the laser beams (7, 8, 9). The device comprises attenuation means (12). The attenuation means is arranged on a downstream side of the one or more light sources (4, 5, 6), and can change light intensity of the light beam (10) by transmitting and/or reflecting one or more beams as a function of supply current to the attenuation means.SELECTED DRAWING: Figure 1
