摘要： A surface light source (4) includes a light guide plate (2) and a light source (5). The light guide plate has an incident surface (21) and an emitting surface (22). The light source is adjacent to the incident surface of the light guide plate for radiating light beams into the light guide plate through the incident surface. The emitting surface defines a large number of prisms (221), in which the distance (L) separating each two adjacent prisms changes according to an intensity of the light beams received from the light source. In particular, the pitch between two prisms decreases with increasing distance away from the light source. By the cooperation of the prisms and the light source, the surface light source has uniform illumination over the whole emitting surface.

摘要： A backlight module (20) includes a light guide plate (22), a light source (21), and a reflection plate (23). The light guide plate includes a light incidence surface (221) for receiving light, a light emitting surface (223) for emitting light, and a bottom surface (222). The light source is disposed adjacent the light incidence surface. The reflection plate disposed under the bottom surface includes a base (232), and a reflection layer (233) formed on the base. The reflection layer defines a number of diffraction grating units (231) at an outer surface thereof. Grating constants of the diffraction grating units progressively decrease with increasing distance away from the light incidence surface. This enables the light emitting surface to output highly uniform light. Further, if the process of fabrication of the diffraction grating units fails, only the reflection plate need be discarded. Thus the backlight module has a low mass manufacturing cost.

摘要： A method for fabricating a molding core (700) for a light guide plate includes: (a) providing a substrate (500) having a photo-resist layer (600) coated thereon; (b) exposing and developing the photo-resist layer to form a photo-resist pattern (640); (c) coating a nickel film (720) on the substrate; (d) electroforming a nickel layer (740) on the nickel film; and (e) separating the nickel layer and film from the substrate and photo-resist pattern, the nickel layer and film thereby providing the core. The nickel film and the nickel layer use a same metal; that is, nickel. Thus, unlike in the prior art, there is no need for an etching step to remove the metal film after electroforming. The method has reduced complexity and cost. In addition, the pattern of the core is more similar to the predetermined pattern of the photo-mask. That is, the precision of the core is significantly increased.

摘要： A heat sink (5) for dissipating heat from an electronic component includes a base (50), and a plurality of fins (52) formed on the base. The base and the plurality of fins are integrally formed by sintering one or two metallic nano-powders. Since the heat sink is integrally formed by sintering, any thermal resistance between the base and the fins is minimized. In addition, because the base and the fins of the heat sink are all made from one or more metallic nano-powders having good thermal conductivity, a surface area of the heat sink is larger than that of a comparable heat sink made by extrusion. Therefore, a heat transfer efficiency of the heat sink is improved.

摘要： A diffusion sheet (23) of the present invention includes a light incident surface (231) having a subwavelength grating (233) formed thereat, and a light emitting surface (232) opposite to the light incident surface. When light beams propagate through the subwavelength grating, they are diffracted forward and backward, to form front diffraction waves and back diffraction waves. Because the subwavelength grating is a zeroth-order grating, it only propagates the zeroth-order diffraction waves. Therefore, based on diffraction theory, the back diffraction waves can be eliminated by adjusting the period T and the shape of the subwavelength grating. If this is done, almost all the incident light beams are transmitted through the incident surface. Thereby, the efficiency of light utilization is enhanced. Moreover, the light beams are diffracted and distributed uniformly. Accordingly, the diffusion sheet yields high uniformity of outgoing light emitted from the emitting surface.
