| 20120075883 | EDGE-TYPE LED BACKLIGHT MOUDLE - The present invention relates to an improved edge-type LED backlight module, comprising: a cover, a printed circuit board (PCB), a plurality of LEDs, a reflective member, a light guide plate (LGP), and a bottom reflective member, wherein the PCB, the plurality of LEDs, and the reflective member are disposed in the cover, the reflective member is used for reflecting a light emitted by the LEDs. A light incident surface of the LGP having a plurality of concave arc-shaped surfaces which are opposite to the plurality of LEDs, respectively, so that, when the light incident into the light incident surface, the light can be extended by the concave arc-shaped surfaces and evenly distributed in the LGP | 03-29-2012 |
| 20100067239 | Lamp shape structure - A lamp shade structure applied to a liquid crystal display backlight module includes a metal hood, an adhesive layer and a reflective sheet, wherein the metal hood is formed by bending a metal sheet into a cross-sectional shape and has a containing space formed at an internal side of the metal hood, the cross-section of the reflective sheet is in an arc shape, and a side of the reflective sheet is attached to the containing space through the adhesive layer. Since the cross-section of the reflective sheet is in an arc shape, therefore the present invention can improve the reflecting efficiency of the lamp shade structure effectively. | 03-18-2010 |
| 20090303747 | HEAT DISSIPATING STRUCTURE OF BACKLIGHT MODULE - A heat dissipating structure of a backlight module includes two light emitting portions and a backlight portion having a light guide plate, a back reflector and a metal clad. The light guide plate is connected to the back reflector. A dent is formed and attached to the light guide plate. The back reflector is connected to the metal clad. Each light emitting portion includes a metal cover, a lamp cup reflector, at least one lamp tube and lamp holders. The lamp cup reflector is attached to the metal cover. A containing groove is formed at the lamp cup reflector and contains the lamp tubes and lamp holders. A thermal conducting plate is extended from the metal cover and contacted with the metal clad. Thus, the heat produced by the lamp tube can be conducted to the metal clad through the lamp holder and the metal cover for heat dissipation. | 12-10-2009 |
| 20090231860 | Lamp reflector structure - A lamp reflector structure includes a metal hood, an adhesive layer and a reflecting plate. The structure is applied to a backlight module of a liquid crystal display, and the metal hood is made by bending a metal plate into a first cross-sectional shape and forms a containing space in the metal hood and dents on the reflecting plate, such that the reflecting plate can be bent to a position corresponding to the dents and into a second cross-sectional shape. A portion of the reflecting plate not corresponding to the dents is attached into the containing space through the adhesive layer, and each bent position of the metal hood is disposed proximate to each dent of the reflecting plate. The reflecting plate is thinner at positions corresponding to the dents, but the remaining portion maintains an even thickness to enhance the reflection index of the lamp reflector structure. | 09-17-2009 |
