Embodiment Construction
[0013] exist figure 1 , 2 The intercooling air flow (1) enters the radiator (10) through the air inlet hole (17) through the light pole (16), the light pole (6), and the ventilation pipe (3), and passes through the fan (9), and the hot air flow (7) is The air outlet (4) is exhausted to form a complete cooling air flow to take away the heat generated by the LED. When the radiator (10) temperature exceeds the temperature controlled by the temperature control switch (13), the fan (9) starts forced exhaust.

The invention relates to an LED street lamp cooling system which reduces the LED working temperature by self cross-ventilation. When the temperature is higher, forced ventilation measures are started by a fan.
Description
technical field [0001] The invention relates to a method for solving heat dissipation in LED lighting, LED display screens and other high altitudes, and is especially suitable for application in LED street lamps. This system mainly relies on air convection to dissipate the heat generated by LED work. When the temperature is too high, the fan works to force the cooling. This system has the advantages of energy saving, simple structure, convenient installation, and strong versatility. It can be used after retrofitting traditional lamps, and has a long service life. technical background [0002] At present, the known heat dissipation of LED lighting generally depends on increasing the heat dissipation area of aluminum or copper radiators or using liquid refrigerants to cool down, and the cost is high, the loss is high, the weight is large, the installation is inconvenient, and the versatility is poor. Contents of the invention [0003] In order to overcome the high cost a...
