Title:
LED ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/078351
Kind Code:
A1
Abstract:
A substrate (23) is fixed to the rear surface side of an inside frame (5). An LED light source (17a) is mounted approximately at the center of the rear surface of the substrate (23). A light emitting surface of the LED light source (17a) is inserted into a through-hole (25a) of a light reflection plate (21a). An outer reflection frame (19) is positioned on the rear surface side of an outside frame (3). Using the inside frame (5) as a reference, the substrate (23) on which the LED light source (17a) is mounted and the light reflection plate (21a) are positioned on the outer reflection frame (19) side (the rear surface side of the inside frame (5)). Furthermore, using the inside frame (5) as a reference, a lens (10), or an inner lens (7) and an outer lens (9), form a convex-shaped part on the side opposite to the outer reflection frame (19) (the front surface side of the inside frame (5)). The convex-shaped part formed by the lens (10), or by the inner lens (7) and the outer lens (9), is a light extraction part which extracts light from the first LED light source.
