    摘要： A lighting fixture includes: a base; a plurality of optical sources attached on an upper surface of the base to emit light; a heat spreader attached to the base to radiate heat emitted from the plurality of optical sources; and a light diffusion lens disposed on the upper surface of the plurality of optical sources to refract light emitted from the plurality of optical sources and to increase an irradiation angle of light. In the lighting fixture, an irradiation angle of light emitted from an optical source is close to that of a general electric-light bulb and thus a light distribution characteristic of the lighting fixture may be improved.
