摘要： A backlight unit includes light sources and optical mixers individually formed between the light sources to reflect light. The light emitted from the light sources becomes uniform while passing the optical mixers. Even when the thickness of the backlight unit is thinner, the brightness distribution of the light becomes uniform.

摘要： A light generating device includes a circuit board and a plurality of light source units. Each of the light source units includes a first light source group and a second light source group. The first light source group includes at least two light sources spaced apart from each other by a first distance and the second light source group including at least two light sources. Each of the light sources of the second light source group is spaced apart from a first virtual line segment connecting centers of the light sources of the first light source group by a second distance that is larger than the first distance. A second virtual line segment connecting centers of the light sources of the second light source group crosses the first virtual line segment. Therefore, a number of light sources is reduced to lower a cost of manufacturing the light generating device

摘要： A lamp assembly includes a lamp and a lamp driving device. The lamp includes a body and first and second electrodes. The body converts invisible ray generated by a discharge into visible ray, and the electrodes are disposed on the body. The lamp driving device provides the first and second electrodes with first and second driving voltages, respectively, to generate the discharge. The first driving voltage is less than a first critical voltage at which a corona discharge occurs at the first and second electrodes. When the first electrode is electrically connected to a ground, the first critical voltage may be about 1,200 volts. When the second driving voltage has an inverted phase with respect to the first driving voltage, the first critical voltage is about 2,400 volts. An ozone gas may not be generated at the first and second electrodes to prevent the damage of the electrodes.

摘要： A backlight for a display device includes a board, a plurality of light emitting diodes (LEDs) mounted on the board, and a light guiding plate that is provided on the LEDs and has light reflecting grooves formed directly on respective LEDs. The light reflecting grooves are formed at an upper surface of the light guiding plate, having a shape of a reversed cone. In this backlight, the light traveling directly upward from the LED is efficiently reflected by total internal reflection and then recycled, resulting in a uniform light distribution of the backlight.
