PROBLEM TO BE SOLVED: To provide a lighting device which enables a thin form, improves the flexibility for product design and heat radiation efficiency, and inhibits wavelength shift and the reduction of the luminous intensity.SOLUTION: A lighting device includes: a light source module 100 which includes at least one light source disposed on a printed circuit board and a resin layer disposed on the printed circuit board for burying the light source; an indirect light emitting part which is formed on at least one of one side and the other side of the light source module and reflects light radiated from the light source; and a diffusion plate which includes an upper part surface contacting with an upper part of the light source module and a side wall which is integrally formed with the upper part surface, extends in a downward direction, and closely contacts with an outer side surface of the indirect light emitting part. |
