SELF GENERATIVE LIGHTING DEVICE

摘要

The present invention relates to a self-generation type lighting device. The lighting device includes: a base; a solar cell plate which is coupled to the base and includes multiple solar cells; a light emitting unit which is coupled to the base and is arranged between solar cells; and a reflection member which is arranged on the upper part spaced apart from the light emitting unit by a predetermined distance and reflects the light emitted from the light emitting unit to the solar cells around the light emitting unit. The present invention generates electrical energy by absorbing the emitted light back to the solar cell plate to continuously generate electricity during days and even at nights, thereby increasing the energy production efficiency. The present invention also has higher energy production efficiency to use the solar cell plate in a smaller size than that of a conventional solar cell plate, thereby reducing the installation cost of a solar lamp.
