ILLUMINATION DEVICE
First Claim
1. An illumination device, comprising:
- an optical lens module comprising a plurality of stepped optical lenses, wherein each of the stepped optical lenses comprises an upper surface, a lower surface opposite to the upper surface, and a side surface between the upper surface and the lower surface;
a light emitting module opposite to the optical lens module, comprising a substrate and a plurality of light sources mounted on the substrate, wherein each of the light sources faces the side surface of each of the stepped optical lenses; and
a reflective layer coupled to the substrate.

Abstract
An illumination device includes an optical lens module, a light emitting module, and a reflective layer. The optical lens module includes a plurality of stepped optical lenses. Each of the stepped optical lenses includes an upper surface, a lower surface opposite to the upper surface, and a side surface between the upper surface and the lower surface. The light emitting module includes a substrate and a plurality of light sources mounted on the substrate. Each of the light sources faces the side surface of each of the stepped optical lenses. Light emitted from the light sources travels to the side surface and is refracted from the side surface. The reflective layer is coupled to the substrate.
