PURPOSE: A lighting device is provided to improve light excitation efficiency by including a light excitation layer which reduces a bending phenomenon. CONSTITUTION: A light source module(200) has one or more light emitting devices. A light excitation plate is arranged on the light source module and includes a base layer, a first fluorescent layer(330), and a second fluorescent layer(350). The base layer passes light. The first fluorescent layer is arranged on one surface of the base layer and includes yellow fluorescent substances. The second fluorescent layer is arranged on the other surface of the base layer and includes red fluorescent substances. |
