technical field

Background technique

Green and environmentally friendly LED lamps are increasingly being used in all aspects of life. In Europe, the government plans to completely use LED lamps for lighting in the next few years, and old high-energy-consuming lamps such as high-pressure sodium lamps will be rolled out on the stage of history. However, in this promotion, there has been an urgent problem to be solved: the heat dissipation problem of high-power LED lamps. Due to the existence of this problem, the promotion of high-power LED lamps has been slow for more than 10 years. High-pressure sodium lamps are still required in some large-scale occasions such as plazas, hypermarkets or large construction sites. When high-power LED lamps are used, even dead lights appear. The phenomenon, the direct consequence of this phenomenon is that the service life of high-power LED lamps is very short. In order to achieve heat dissipation, most of the LED lamps available on the market adopt the method of increasing the heat dissipation area of the radiator or using synthetic materials with better performance, but this does not increase the area of the effective heat dissipation surface, but instead increases the unused heat dissipation surface. The weight of the whole light fixture is increased, and when the light fixture is installed on the street light pole, the degree of danger is increased. In addition, when high-power LED lighting is applied, it needs to input a voltage higher than 220 volts to maintain its work, and its design does not really achieve the effect of energy saving.

The sealing cover 4 fits on the periphery of the heat dissipation fins 21 to form a shell and protect all the heat dissipation fins 21 . The LED light source 1 is arranged at the lower part of the heat sink 2, the glass lens 3 is fitted on the lower part of the heat sink 2 and is located below the LED light source 1, and the glass lens 3 is provided with an opening 31 .

A photoelectric silicon plate 5 is arranged on the upper side of the glass lens 3 near the edge. When the LED light source emits light, the light passes through the light-transmitting hole 91 and irradiates on the solar silicon plate 5. The existence of the reflector 9 makes the light passing through the light-transmitting hole 91 reflect The solar energy silicon plate 5 is irradiated more intensively, which can make the efficiency of the solar energy silicon plate 5 higher. The function of the solar silicon plate 5 is to convert the received light energy into electrical energy, and the more light received by the solar silicon plate 5, the more electrical energy will be generated.

The two end surfaces of the cylindrical radiator 2 are equipped with a street lamp plug 7 and a street lamp handle 8 respectively, and the inside of the street lamp plug 7 is provided with an inner hole 71. The matching end of the radiator 2 is also provided with a fan installation hole I72, and the inner hole 71 communicates with the fan installation hole I72 and directly leads to the other end surface. The end of the street lamp handle 8 that matches the radiator 2 is provided with a fan installation hole II 81, and the street lamp handle 8 is also provided with a lamp post installation hole 82, and the lamp post installation hole 82 is used for The lamp post of the street lamp is matched, and the installation hole 82 of the lamp post communicates with the installation hole II 81 of the fan.
