LIGHTING DEVICE

摘要

PURPOSE: A lighting device is provided to prevent the degradation of light uniformity by using a first light emitting module which is more light efficient than a second light emitting module. CONSTITUTION: A light emitting module is arranged at one side of a light source body(9800). The light emitting module comprises a first light emitting module(9810) and a second light emitting module(9820). The first light emitting module is arranged at the central part of the one side of the light source body. The second light emitting module is arranged at the side of the first light emitting module. The light efficiency of first light emitting module is higher than the light efficiency of the second light emitting module.
