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.

摘要： A lens includes a convex surface formed in an outer surface thereof facing away from a light source to uniformly distribute light emitted from the light source; a concave surface concaved inward from an inner region of the convex surface, around an optical axis; and a convex portion convexed outward from a central region of the concave surface, which the optical axis intersects, in order to enhance quantity of light around the optical axis. The lens refracts light beams falling onto the respective areas thereof at different angles, thereby producing a uniform light distribution within a specific lighting range, but does not create a dark area around an optical axis.
