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.

摘要： There is provided a back light unit having a light guide buffer plate. The back light unit having a light guide buffer plate includes a light source for generating the light when a power source is applied; a light guide panel whose light-receiving vertical surface that the light emitted from the light source enters is provided with a first prism pattern and whose bottom surface is provided with a refraction pattern, thereby converting the incident light from the light-receiving vertical surface into a surface light source; a reflection unit disposed in a bottom surface of the light guide panel to reflect light toward the light guide panel; and a buffer disposed between the light source and the light guide panel and whose light-emitting vertical surface corresponding to the light-receiving vertical surface of the light guide panel is provided with a second prism pattern. The back light unit can be useful to improve visibility, a mixing property and uniformity by basically removing a poor-visibility zone, which is formed in an end of the light guide panel, without any changes in the structure of the light guide panel.
