Abstract
An LED illumination apparatus includes a substrate, a light source disposed on the substrate, a cover unit to cover the light source, and a reflector configured to extend from the cover unit inside to the upper substrate, whereby a light generated by the light source illuminates an area below a bottom side of the substrate.
Claims18
An illumination apparatus, comprising:
- a substrate comprising a front surface and an opposing rear surface;
- a light source disposed on the front surface of the substrate;
- a cover unit configured to cover the substrate;
- a reflector extending toward the substrate from the inside of the cover unit, the reflector configured to reflect at least a portion of light emitted from the light source toward an area in front of the rear surface of the substrate and inside of the cover unit.

An illumination apparatus, comprising:
- a substrate comprising a front surface and an opposing rear surface;
- a first light source and a second light source disposed on the front surface of the substrate;
- a cover unit covering the front surface of -the substrate;
- a reflector disposed inside the cover unit, the reflector comprising:
- a curved outer surface configured to reflect at least a portion of light emitted from the first light source toward an area in front of the rear surface of the substrate and inside of the cover unit;
- and
- an opposing inner surface that at least partially defines an opening exposing the second light sources, wherein light emitted from the second light source is projected through the opening;
- and
- support members extending from the reflector to the cover unit, the support members configured to suspend the reflector from the cover unit toward the front surface of the substrate.
