Abstract:
The purpose of the present invention is to realize a lighting device of thin, low power consumption and small light distribution angle. The present invention takes the following structure to realize the above task:
A lighting device having an emitting surface and a bottom opposing to the emitting surface including: a resin, set between the emitting surface and the bottom, having a hole at a center, a reflection block set in the hole at a side of the emitting surface, an LED, which is a light source, set in the hole at a side of the bottom, a space between the LED and the reflection block, in which the resin is contained in a container whose inner surface is a reflecting surface.
