There is no fan and a windshield to prevent backflow. The fan draws the cold air into the zijinzheng fins, and then the heat is quickly discharged through the bottom air outlet of the lamp housing. [Prior Art], check the existing heat dissipation structure of high-power LED lighting, mostly using t, cold metal sheet metal heat sinks, the use of this heat dissipation effect, so the requirements for the overall related heat-resistant structural material High, otherwise poor heat dissipation will lead to premature LED light decay and short life, and for better U fruit, you can only seek good heat dissipation metal, or increase its heat dissipation = product has obtained better efficiency, but this is Increasing the size of the luminaire to the eye: the product is refined and efficient, it does not meet the industrial needs. In view of this, the creator of this case is born with a sense of innovation, and has been practicing the experience of LED lamp production for many years. It is a practical benefit to meet the needs of the industry in the present era. Mouth [new content] τ team Benhuang: two main # aims to provide a kind of forced air cooling heat power k 'including lamp shell, lampshade, substrate, led lamp, alloy shattered j fan, windshield and electronic ' When mil provides great power (four), i will quickly force the industrial use value of heat dissipation. The second objective of Huanwen's creation is to provide a forced air-cooling heat-dissipating high-power 5 M342473 led lamp. Specifically, the inner surface of the lamp housing is provided with an alloy heat sink. When the led light on the substrate generates high thermal energy, the forced wind The cold fan is started, and the cold air is sucked from the top of the lamp housing into the air outlet and flows through the alloy to dissipate 2 pieces', and then the LED lamp generates heat energy through the bottom of the lamp housing. The other is to create a kind of forced air-cooling heat-dissipating large LED light. By. [Embodiment] For the sake of your review, there is a solution to the structure and characteristics of this (4)! Xuan cited a better implementation of the financial diagram as follows: Please refer to the first to second figures, this creation provides a forced air cooling high-power LED lights, including lamp housing 灯, lampshade 2, US 3, lights 4, alloy radiator 5, fan 6, windshield 7 and ^ strange flow device 8 and so on, its main improvement: the traditional lamp housing i above the inlet: port 11 and the lower air outlet 12, the inside of the lamp housing The sequential supply and the electronic constant current are 8, the air baffle 7, the fan 6, the alloy radiator 5, and the substrate 3 are placed; the lamp cover 2' is placed under the lamp housing 1 to open; the substrate 3 is provided with an LED lamp below 4; alloy heat sink ϋ 5, is a (four) type heat sink connected to the back of the substrate 3 'fan 6 , is placed above the alloy heat sink 5 ; the wind shield 7 , a plate to prevent backflow is placed above the fan 6 ; electronic constant current 8 , Provides the power supply for the substrate 3 and the fan 6, which is the main structure of the creation. In the implementation of the present invention, when the LED on the substrate 3 emits high thermal energy, the forced air-cooling fan 6 is simultaneously induced to start, and the cold air is sucked from the top of the lamp housing into the tuyere 11 and flows through the partition plate 7 to the alloy radiator tab 5 Then, the heat generated by the LED lamp is discharged through the bottom air outlet 12 of the lamp housing, wherein the air-proof M342473 plate 7 has the effect of preventing the upward flow of the hot air of the alloy radiator 5, and effectively utilizing the industrial value of the heat dissipation. In summary, the creation of this case is based on the fact that the high-power LED lamp of the formula is not easy to dissipate heat and keeps the I. It is true that the car has a specific multiplier effect, and it is also considered to be a patent law. Bey's patents are inspired by the innovation of the people of the country!
