However, the heat dissipation structure of the LED light source in the prior art generally uses aluminum alloy structure heat sinks or heavy-duty aluminum injection parts for heat dissipation. The disadvantages of high cost and inability to effectively cool down the LED lights during work are not ideal, and it is not suitable for use on high-power LED lights above 150 watts; in addition, due to the heat dissipation of aluminum profiles, large The cascade temperature often makes the LED light-emitting diode as a light source work under high temperature conditions, and sometimes the LED light-emitting diode will even work at a temperature higher than 70 ° C, so that the LED light-emitting diode will age in advance and appear Substantial light decay phenomenon, its luminous efficiency is greatly reduced, which not only increases the energy consumption of LED light-emitting diodes, but also greatly shortens its service life and increases the cost of use; and the existing high-power LED street lamps are due to heat dissipation The needs of the heat sink must be made very large, so there are still problems such as large volume and heavy weight.

Therefore, the structure of the existing LED street lamps using LED light-emitting diodes as the light source is still not ideal, and the energy-saving advantages of the existing LED light source cannot be fully utilized.
