Problems solved by technology
[0007] The present invention designs a high-power LED lamp, which solves the technical problems as follows: (1) The defect of the existing high-power LED lighting lamp is that the high-power LED will release a large amount of heat, and the heat is not easy to discharge from the lamp body, and the time is long It is easy to affect the service life of LED lamps; (2) The N-type electrode area is relatively small, and it is difficult to align with the corresponding area of the PCB board, which will affect the packaging effect and the excellent rate of LED products; (3) The position of the N-type electrode is more than P The position of the N-type electrode is much higher, which is easy to cause virtual soldering and desoldering; (4) In order to make the N-type electrode, it is often necessary to artificially remove a large part of the active area, which greatly reduces the light-emitting area of the device and directly affects the LED Luminous Efficiency

Embodiment Construction
[0031] Combine below Figure 1 to Figure 5 , the present invention is further described:
[0032] like figure 1 and figure 2 As shown, a high-power LED lamp includes a hollow fixed tube 31 and a plurality of heat dissipation fins 32. The plurality of heat dissipation fins 32 are distributed on the hollow fixed tube 31 in a layered structure, and the plurality of heat dissipation fins in each layer 32 is fixed on the hollow fixing tube 31 in a scattering manner. Therefore, a large amount of heat emitted by the high-power LED lamp can be transferred out of the lamp through the above-mentioned hollow fixed tube 31 and the plurality of cooling fins 32, prolonging the service life of the high-power LED lamp and ensuring the lighting effect.
[0033] The cooling fins 32 are straight hollow copper tubes or corrugated hollow copper tubes. The hollow fixed pipe 31 is made of metal copper. Metallic copper has particularly good thermal conductivity characteristics.

The invention relates to a high-power LED (Light Emitting Diode) lamp. The high-power LED lamp comprises a heat radiating device and a high-power LED, wherein the heat-radiating device comprises a hollow fixing tube (31) and a plurality of heat radiating fins, wherein the heat radiating fins (32) are distributed on the hollow fixing tube (31) in a laminar structure; the heat radiating fins (32) on each layer are fixed on the hollow fixing tube (31) in a scattering way; and the high-power LED (20) and a lamp shade (10) are connected to the upper side of the heat radiating device. The high-power LED lamp is characterized in that the high-power LED (20) is an LED chip with a flip chip structure. According to the high-power LED lamp disclosed by the invention, the high-power LED lamp comprises the hollow fixing tube and the heat radiating fins and the heat radiating fins are distributed on the hollow fixing tube in a laminar way, so that a great amount of heat emitted by the high-power LED lamp can be transferred out of the lamp by the hollow fixing tube and the heat radiating fins, the service life of the high-power LED lamp is prolonged and the illuminating effect is ensured.
Description
technical field [0001] The invention relates to an LED lamp, in particular to a high-power LED lamp. Background technique [0002] Using LEDs directly as lighting fixtures has the following advantages: 1. LEDs consume 80% less energy than incandescent lamps with the same light efficiency; 2. LEDs have no harmful metal mercury and will not pollute the environment; 3. LEDs use low-voltage power supplies, and the power supply voltage is within Between 6-24V, depending on the product, so it is a safer power supply than using a high voltage power supply. [0003] The use of high-power LEDs can reduce the number of LEDs used while meeting the effect requirements of lighting brightness, but the defect of existing high-power LED lighting fixtures is that high-power LEDs will release a lot of heat, and the heat is not easy to discharge from the lamp body. A long time will easily affect the service life of LED lamps. [0004] In addition, the position of the N-type electrode is far ...
