LIGHT GENERATING UNIT, BACKLIGHT ASSEMBLY HAVING THE UNIT AND METHOD OF MAKING THE UNIT

摘要

A light generating unit is provided to prevent air bubbles from being formed in a coupling part when a lens part is coupled to a body part by the coupling part by making the lens part include a pressurized protrusion of a round shape. A light emitting diode(120) is formed on one surface of a body part(110), generating light. A lens part(130) is disposed on the light emitting diode, including a lens body for diffusing the light and a pressurized protrusion(132) of a round shape formed on the lower surface of the lens body. A coupling part(140) is formed on one surface of the body part to cover the light emitting part, coupling the lens part to the body part. The body part can have a cylindrical shape and the lens body can have a hemispherical shape. The pressurized protrusion can be formed on the center of the lower surface of the lens body.
