PURPOSE: A lighting device is provided to reduce the manufacturing cost by not requiring the top cover by combining the diffusion plate with the cover plate. CONSTITUTION: A lighting device comprises a cover plate(100), a light emitting substrate(200), and a diffusing plate(300). The diffusing plate is fixed and coupled to the cover plate. The diffusing plate is located on the top of a light emitting diode. The top and the diffusing plate of the light emitting diode are isolated with a fixed interval. |
