Title:
REFLECTOR AND LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/025816
Kind Code:
A1
Abstract:
A reflector (3) is provided with a plurality of first reflective surfaces (31) and a second reflective surface (32). The plurality of first reflective surfaces (31) are each disposed around a plurality of LED devices and farther forward in the light axis direction than the light emission surface of the plurality of LED devices, which are arranged linearly. The second reflective surface (32) is disposed on the forward side of the plurality of first reflective surfaces (31) in the light axis direction. The second reflective surface (32) widens continuously in the lengthwise direction on one side of the LED device array in the width direction. In the reflector (3), the first reflective surfaces (31) are disposed on both sides of the LED cross sections in the width direction, and face outward in the width direction from the LED devices in progress toward the forward side in the light axis direction. Also, in the LED cross sections, the second reflective surface (32) faces outward in the width direction in progress toward the forward side in the light axis direction. It is thereby possible to achieve a desired illuminance of illumination light, while non-uniformity of brightness due to the plurality of LED devices is suppressed.
