摘要： The present invention relates to an improvement for a light guide structure for light guide plate so as to resolve the problems of illumination and degree of uniformity of the conventional light guide plate. The light guide plate of the present invention has line-shaped passages which are located in parallel with the direction of light from the light emitting diodes. The depth of the passages becomes deeper gradually from one end to the other, wherein the source of light is located close to the shallow end, thereby the light from the light emitting diodes is transmitted to the remote areas that are located far from the source of light. The present invention increases the total illumination and the degree of uniformity, and the efficiency of the light emitting diode is also increased.

摘要： The high efficiency light emitting diode apparatus mainly comprises a connector, a heat dissipating body, a light generator, a central venting portion, and a transparent casing. This connector has a flow guider, a flow chamber and a vent. The light generator contains several LEDs. The heat dissipating body includes an inner passage and an outer passage. The central venting portion has a central channel. An inner flow path and an outer flow path are formed. So, the heat dissipating effect of the flow paths is excellent. The structure forming two flow paths can enhance the heat dissipating effect. The auxiliary element can strengthen the overall illuminating effect. Plus, the auxiliary element can make the light more uniformly.
