Problems solved by technology

However, its structure itself is bulky, and the LED lamp located in the light-transmitting cover has low heat dissipation efficiency due to self-heating, resulting in a short service life.
Moreover, due to the self-heating of high-power LED street lights, high-power LED street lights with this type of structure can only be used in lighting sections with a pole height of 8-10 meters. If the pole exceeds 10 meters, the brightness cannot meet the lighting requirements.

Abstract

The invention relates to an LED street lamp, in particular to a hollow-out high-power LED street lamp, which includes a base, a tailstock, a high-power LED lamp, a radiator and a power supply; Hollow support rods; a heat sink is fixed between the two support rods, and the high-power LED lamp is fixed on the top end surface of the heat sink; the heat sink has a plurality of through holes, and the plurality of through holes The hole connects the top end face of the heat sink and the bottom end face of the heat sink, so that a hollow part is formed between the top end face of the heat sink and the bottom end face of the heat sink; the power supply is connected to the high-power LED lamp through a cable, and the cable passes through The wire passing hole is arranged on the support rod; the power supply is also provided with a connecting wire, and the connecting wire passes through the pipe joint. The advantages of the present invention due to the structure are: increased heat dissipation speed, prolonged service life and reduced use cost.

Description

technical field [0001] The invention relates to an LED street lamp, in particular to a hollow-out high-power LED street lamp which improves heat dissipation speed, prolongs service life and reduces use cost. Background technique [0002] LED lights are widely used in indoor and outdoor lighting because of their energy-saving properties. The high-power LED street lamp disclosed in Chinese patent 201410554632 reduces energy consumption to a certain extent and can be effectively applied to outdoor lighting. However, the structure itself is bulky, and the LED lamp located in the light-transmitting cover has low heat dissipation efficiency due to self-heating, resulting in a short service life. And because of the self-heating of high-power LED street lamps, high-power LED street lamps of this type of structure can only be used in lighting sections with a lamp pole height of 8-10 meters. If the lamp pole exceeds 10 meters, the brightness cannot meet the lighting requirements. C...
