摘要： A light-emitting diode (LED) (10) includes a chip body (103), an encapsulation can (105) surrounding the chip body, and a base (106) supporting the encapsulation can and the chip body thereon. Numerous diffusion structures (1050) are provided on the encapsulation can. With the diffusion structures, light beams from the chip body are diffused and attain wider irradiation angles. A backlight system (900) includes a light guide plate (20), and a number of LEDs as per the above. The LEDs are disposed adjacent to the light guide plate. Light beams having wide irradiation angles are emitted from the LEDs and enter the light guide plate. This enables a light exit surface of the light guide plate to have highly uniform brightness.

摘要： A light guide plate mold core (1) includes a main body (13) having a molding surface (12) and a plurality of concavities (13a) formed at the molding surface. The main body is made of a material whose thermal conductivity is limited in the range from 0.002 cal/cm.s.K. (calories/centimeter.second.Kelvin) to 0.009 cal/cm.s.K. The thermal conductivity of the material for the light guide plate mold core is less than that of stainless steel. Therefore the rate of spreading of heat in the light guide plate mold core is lower than that of a conventional light guide plate mold core, so that stresses within a formed light guide plate can be released more. Thus by using the light guide plate mold core, a light guide plate having a highly even bottom surface can be manufactured. A method for manufacturing the light guide plate mold core is also provided.
摘要翻译：导光板模芯（1）包括具有模制表面（12）的主体（13）和在模制表面形成的多个凹部（13a）。主体由导热系数限制在0.002cal / cm.s.K范围内的材料制成。（卡路里/厘米。开尔文）至0.009cal / cm.s.K。导光板模芯材料的导热系数小于不锈钢。因此，导光板模芯中的热扩散速度比常规的导光板模芯的散热速度低，从而可以更多地释放形成的导光板内的应力。因此，通过使用导光板模芯，可以制造具有高度均匀的底面的导光板。还提供了一种制造导光板模芯的方法。

摘要： A light guide plate (2) into which light beams are introduced from a light source has a light incident surface (21) receiving the light beams, a light emitting surface (22) transmitting the light beams therethrough, and a bottom surface (23) opposite to the light emitting surface. The light incident surface is between the bottom surface and the light emitting surface. The bottom surface has at least two sets of diffusing elements (231, 232) for diffusing and reflecting light beams toward the light emitting surface. Each set forms a continuous region at the bottom surface, and the at least two sets totally cover the bottom surface. The at least two sets of include diffusing elements that are formed along two different directions. By utilization of the at least two sets of diffusing elements, the light guide plate provides a uniform luminance over the whole of the light emitting surface.
