Abstract
A light emitting device includes a light reflector and a first light source. The light reflector includes a first concave surface and a second concave surface immediately adjacent to the first concave surface. The convex ridge is located between the first and second concave surface and has an apex line extending along a direction. The first light source is located at a side of the first concave surface and opposite to the convex ridge. The first light source has a first emitting surface facing the convex ridge. The convex ridge has an apex located higher than a bottom of the first emitting surface, but lower than a top of the first emitting surface.
Claims9
A light emitting device comprising:
- a light reflector comprising a first concave surface and a second concave surface immediately adjacent to the first concave surface, a convex ridge being disposed between the first and second concave surface and having an apex line extending along a direction;
- and
- a first light source being disposed at a side of the first concave surface and opposite to the convex ridge, wherein the first light source has a first emitting surface facing the convex ridge, and the apex line is disposed farther from a bottom surface of the light reflector than a bottom of the first emitting surface, but closer to the bottom surface of the light reflector than a top of the first emitting surface,
- wherein the first concave surface has an opening width and the first light emitting surface has a height, the opening width is about 2.8 times to about 5.8 times of the height.
