LED street lamp based on high-brightness coaxial light source

Abstract

The invention discloses an LED street lamp based on a high-brightness coaxial light source. The LED street lamp comprises a street lamp pole and heat dissipation holes, a base is fixedly arranged on the outer side of the lower end of the street lamp pole, a connecting column is fixedly mounted on the outer side of one end of the street lamp pole, an LED street lamp body is fixedly mounted on the outer side of one end of the connecting column, and an ultrasonic insect expelling device is fixedly arranged on the outer side of one end of the LED street lamp body. According to the LED street lampbased on the high-brightness coaxial light source, a coaxial LED light source array, a coating film splitting filter, the ultrasonic insect expelling device and a standby small lamp are arranged, illumination provided by the coaxial light source is more uniform than that of a traditional light source, the illumination degree and the illumination uniformity of the street lamp are improved, meanwhile, the light loss is reduced, mosquitoes around the street lamp can be effectively repelled by the aid of the ultrasonic waves, the influence on the illumination effect is avoided, the standby illumination is further provided, the trouble about damage to the headlamp is solved, people can use the lamp conveniently, and a better application prospect is brought about.

Description

technical field [0001] The invention relates to the field of LED street lamps, in particular to an LED street lamp based on a high-brightness coaxial light source. Background technique [0002] The difference between LED street lamps and conventional street lamps is that the LED light source adopts low-voltage DC power supply and high-efficiency white light synthesized by GaN-based power blue LED and yellow. It has unique advantages such as high efficiency, safety and high color rendering index, and can be widely used in roads; existing There are certain disadvantages in the use of advanced LED street lights. Without the use of coaxial light sources, the brightness of the lighting is not enough, and the lighting is not uniform enough. In summer, due to the phototaxis of mosquitoes, the lighting effect is affected. When the lighting lamp is damaged, there is no spare Lighting lamps cannot meet people's needs and have a certain impact on people's use process. Therefore, we pro...

[0002] The difference between LED street lamps and conventional street lamps is that the LED light source adopts low-voltage DC power supply and high-efficiency white light synthesized by GaN-based power blue LED and yellow. It has unique advantages such as high efficiency, safety and high color rendering index, and can be widely used in roads; existing There are certain disadvantages in the use of advanced LED street lights. Without the use of coaxial light sources, the brightness of the lighting is not enough, and the lighting is not uniform enough. In summer, due to the phototaxis of mosquitoes, the lighting effect is affected. When the lighting lamp is damaged, there is no spare Lighting lamps cannot meet people's needs and have a certain impact on people's use process. Therefore, we propose a LED street lamp based on a high-brightness coaxial light source
