The three inventions ingeniously solve the two common problems of LED high-power street lamp heat dissipation and power supply life problems, ensuring that the use of LED high-power street lamps is truly in the practical stage.
Invention 1 Liquid automatic circulation cooling (Patent No.: 200910083421.4)
The basic principle is to use the heat emitted by the LED when it is energized to make the liquid flow upward and heat in the circuit composed of the lampshade, the bracket and some of the lampposts. This heat dissipation method is the third generation heat dissipation method of the company.
The first generation of heat dissipation is fin-type heat dissipation. Although this heat dissipation method is old, it is effective. However, LED street lamps are mostly installed on the side of the road and are susceptible to dust, leaves and bird droppings, thus making the heat dissipation invalid. Therefore, it will be eliminated.
The second generation uses heat pipe heat conduction, the terminal uses a large area of metal plate to dissipate heat, which can overcome some problems of the first generation heat dissipation method, but the heat pipe must be highly sealed and maintain vacuum, with the decrease of vacuum degree, heat transfer The effect is gradually reduced, and it is completely lost.
The first and second generation products of the company will be replaced and recalled for scrapping.
The third generation of heat dissipation is simple and easy, overcomes all the shortcomings of the first and second generation, and has good heat dissipation, ensuring temperature rise in any environment <14 C
Invention II High-life electrolytic capacitor (Patent No.: ZL20112005899.6 invention patent)
In LED high-power street lamps, more than 90% of the faults come from power supply equipment, and 90% of the faults in the power supply are affected by the existence of electrolyte in the electrolytic capacitor. When the amount of electrolyte is reduced or dried, the capacitance will change or even Complete failure, and traditional electrolytic capacitors are unlikely to solve this problem. The high-life electrolytic capacitors invented by the company can ensure that the electrolyte will never dry, and the safety performance is better than the traditional electrolytic capacitor.
Invention III High Life LED Power Supply (Patent No.: 201120146263.5)
Conventional LED street lamps generally use a switching power supply as a driving power source. In principle, a switching power supply is a power source having many advantages. For example, the power factor and efficiency are relatively high, but the switching power supply has its own weakness (the system reliability is difficult to guarantee, it consists of several hundred electronic components, as long as one component has a problem, the whole system will not work properly. As a result, the LED street light flashes or goes out. Especially the LED street light is installed on the roadside, the working environment is poor, and the switching power supply is easily damaged.
The LED power supply invented by the company has gone out of the routine of the switching power supply. It is simple, sturdy and durable. It is suitable for long-term work in harsh environments. It can be guaranteed for more than 10 years!
