RADIATION DEVICE
Document Type and Number:
Japanese Patent JP2017016954
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a radiation device having each floodlight automatically directed outward in the state of an elevation angle of -90 degrees, at which the direction of radiation of a light directed rightly below.SOLUTION: In this radiation device 100, floodlights 20a to 20b' automatically direct outward when a lighting part 90 is at a lighting position directly below an elevation angle of -90 degrees. As a result, a work site can be lighted over a wide range. In the region of the elevation angle of the lighting part 90 at or over a predetermined angle, moreover, the elevation angle of the floodlights 20a to 20b' is kept substantially at 0 degrees so that the normal direction of the lighting part 90 and the irradiation direction of the floodlights 20a to 20b' are substantially identical. As a result, the lighting part 90 can illuminate a distant object in high luminance. Moreover, the change and maintenance of the elevation angle of those floodlights 20a to 20b' are performed by a linkage 50 in a mechanically interlocked manner with the revolving actions of lighting arm parts 40 and 40'.SELECTED DRAWING: Figure 1
