    摘要： Disclosed is a backlight unit. The backlight unit includes a printed circuit board formed thereon with a plurality of LEDs and a light guide member having receiving holes to receive the LEDs. At least one round part having a predetermined curvature is formed at an edge defined in an intersection between an upper surface and an inner surface of the receiving hole. Since the round part is formed at the edge in the receiving hole receiving the LED at the portion of the light guide member, the light distribution is improved so that the light efficiency is increased.

    摘要： A light unit is provided. The light unit includes a PCB mounted with a plurality of LEDs, and a light guide member having a plurality of reception grooves piercing therethrough and receiving the LEDs, wherein the light guide member includes one surface and the other surface opposite to the one surface, and the one surface of the light guide member is further coated with the resin material. The reception grooves are formed in the light guide member and are filled with a fluid resin material, thus preventing the damage to the LED caused by the difference between the thermal expansion rates of the components such as the light guide member, the reflection film and the PCB.

    摘要： The present invention provides a light unit, comprising a printed circuit board equipped with a plurality of LEDs; and a light guide member equipped with mounting grooves to house the LEDs. It is preferred that the light guide member comprises one surface and another surface facing the one surface; a first density pattern area and a second density pattern area having higher density than that of the first density pattern area are formed in the one surface; and the second density pattern is disposed in an area closer to the light emitting surface of the LED than the first density pattern area.According to the present invention, hot spots can be removed by forming high density optical patterns on the upper surface of a light guide member and diffusing the light of LEDs; meanwhile, the transmission range of light can be extended and light extraction efficiency can be improved by disposing low density optical patterns in adjacent areas.
