Problems solved by technology

Especially for high-power LED lighting fixtures, but high-power LED lighting equipment mainly adopts natural heat dissipation, which not only consumes a lot of energy, but also increases the power of the LED current and generates a lot of heat, which will also reduce the service life of the LED.
The luminous efficiency of LED will decrease with the increase of time and frequency of use, and the high temperature of PN junction will reduce the luminous efficiency of LED, so the heat dissipation problem has become the bottleneck of high-power LED lamps
The luminous efficiency of LED is inversely proportional to the working temperature, especially for products with blue LED as the basic light source and coated with YAG phosphor white light technology, the aging of the phosphor will be accelerated when the PN junction temperature is higher than 50°C. , reduce lamp life
Low-power LED lamps below 20W can adopt natural heat dissipation method, but if high-power LED lamps adopt natural heat dissipation method, a large amount of metal materials must be used to increase the heat dissipation area, which reduces the safety of high-power LED lamps

Embodiment 1

[0011] Embodiment 1 is a 200W series radiator street lamp, according to figure 1 and figure 2 shown.

Embodiment 2

[0012] Embodiment 2 is a 200W parallel radiator street lamp, according to image 3 and Figure 4 shown.

Embodiment 3

[0013] Embodiment 3 is a 400W series-parallel radiator street lamp, according to Figure 5 and Image 6 shown.

[0014] According to implementation forces 1, 2, and 3, the high-power LED lamps conduct the heat generated by the integrated and packaged LED light source module (1) to the fins of the heat pipe at the speed of sound through the heat pipe radiator with fins, and then dissipate the heat. The fan (3) can effectively dissipate heat from the integrated and packaged LED light source module (1) by means of forced heat dissipation. Many high-power lamps are generally used outdoors. In order to prevent dust from entering the lamp housing, a dust-proof air filter (4) is designed. In order to prevent the dust-proof air filter (4) from being blocked by dust, the present invention designs a blowback blowdown When the fan (5) and blowback exhaust fan (5) are working, the air inlet (17) is converted into the air outlet (18), and the air outlet (18) is converted into the air inl...

Description

technical field [0001] The invention relates to an LED lighting fixture, in particular to a high-power LED lighting fixture. Background technique [0002] Light-emitting diodes (LEDs) have the advantages of low energy consumption, power saving, long life, and durability, so they will replace traditional lighting and become the future lighting source. Especially for high-power LED lighting fixtures, but high-power LED lighting equipment mainly adopts natural heat dissipation, which not only consumes a lot of energy, but also reduces the service life of LEDs due to the large amount of heat generated by the LED current heat as the power increases. The luminous efficiency of LED will decrease with the increase of time and frequency of use, and the high temperature of PN junction will reduce the luminous efficiency of LED, so the heat dissipation problem has become the bottleneck of high-power LED lamps. The luminous efficiency of LED is inversely proportional to the working tem...
