New description: [New technical field] This creation is about a L E D projection lamp structure, especially a projection lamp with good heat dissipation efficiency. [Prior Art] Projected lamps are widely used because of their high illumination, such as indoor lighting and commercial display. The inside of the traditional projection lamp is a high-power bulb as a light source. Although it can achieve a strong light effect, it is accompanied by power consumption and high heat. After that, due to the rapid advancement of the manufacturing technology of light-emitting diodes (LEDs), the luminosity emitted by them is enough to be used as a lighting fixture. In the modernization of energy saving and carbon reduction, LEDs have low power consumption characteristics, and all LEDs are replaced by LEDs. The inevitable trend of future development. In the known technology, the disclosure of a projection lamp using L ED as a light source has been made, for example, in the case of the new patent M297441 "LED projection light source module" of the Republic of China, which provides an LED projection light source module. Mainly composed of a main body LED unit, a heat dissipating unit, a voltage conversion unit and a base, wherein the main system is made of a metal material (for example, copper) having a better heat conduction efficiency, and the main body is provided with a housing space. The LED unit is accommodated, and the Wei unit is connected between the LED unit and the voltage conversion unit, and the electric (4) changing unit is disposed inside the base. The bottom surface of the base is combined with the main body of the base. The bottom surface of the base is provided with a conductive pin that can be matched with the lamp holder. One end of the conductive pin is electrically connected with the voltage conversion unit; the loose element is disposed at the outer edge of the main body, and the heat source produced by the LE d unit M392918 can be effectively transmitted to the heat dissipating unit through the main body. The effect of dissipating heat dissipation efficiency, so that the brightness of the higher wattage L ED unit is used.
然而，在麟案中’金屬材質的主體是為—端封閉的筒 體，L E D所發出的熱量僅能利用主體與外表連接的多片散熱 鯧片作熱傳導而散熱’而這些散熱鮪片被裝置在一封閉的投射 燈座内，這導致了散熱效果仍不佳的問題，還有待改盖。 【新型内容】 針對先前技術之問題點，本創作提供了一種L E D投射燈 結構，係包括： 一底板，該底板中間設有一空心孔； 一風扇，該風扇連接於底板之空心孔相對位置；However, in the case of Lin, the main body of the metal material is a cylinder that is closed at the end, and the heat generated by the LED can only be dissipated by heat conduction by using a plurality of heat-dissipating fins connected to the main body and the external surface, and these heat-dissipating fins are installed. In a closed projection lamp holder, this leads to the problem that the heat dissipation effect is still not good, and it needs to be changed. [New content] In view of the problems of the prior art, the present invention provides an L E D projection lamp structure, comprising: a bottom plate having a hollow hole in the middle; a fan, the fan being connected to the relative position of the hollow hole of the bottom plate;

The structure of the LED projection lamp provided by the present invention is compared with the previous case disclosed in the prior art, except that the heat dissipation function of the original heat dissipation fin is maintained, and the arrangement of the 4 M392918 gas heat conductive tube body is made to make the light emitting module The generated heat energy - _ hot bottom plate to heat dissipation (four) dissipated heat energy, and the other side is discharged through (4) heat extraction == the longer space between the head and the composition. Due to the two wide heat dissipation paths, the natural heat dissipation function is much better than the prior art, which is a great improvement for the L E D lamp that emits = heat.
