LED road lamp

Abstract

The invention discloses a LED road lamp, comprising a connecting seat, a power bin connected with the connecting seat, power provided inside the power bin and a LED light group connected to the power bin. The LED light group comprises a plurality of LED modules. The plurality of LED modules is fixed via two side covers and front covers, and the side covers are connected to the power bin via screws. The LED modules comprise a module aluminum substrate for arranging LED, a module radiator arranged on the backside of the module aluminum substrate, and a module lens arranging on the module aluminum substrate. Gaps are among the LED modules and are evenly distributed. Heat dissipation energy efficiency is greatly enhanced through uniformly spaced distributed LED modules and upper and lower permeability of the LED modules. A LED light emitting module is sealed between the module lens and the module radiator by using a sealing ring, waterproof effect is good, and screws with rubber pads are used to prevent water vapor permeability. Light source and power source radiate independently, resist water independently with no need of glue, and have better heat dissipation and waterproof effects.

Description

technical field [0001] The invention relates to an LED street lamp. Background technique [0002] With the continuous innovation and development of LED upstream technology, LED lighting technology is becoming more and more mature, and the advantages of energy saving, environmental protection, and long life are becoming more and more significant. Almost all types of lighting fixtures have begun to use LED light sources, which are recognized as the next generation of lighting technology. LED street light products are widely used in road, square and garden lighting just like traditional street lights. Under the condition of meeting the lighting design standards, compared with traditional street lights, LED street lights can not only create good economic benefits (saving more than 50% of electricity costs and 90% of maintenance costs), but also produce great social benefits (saving energy and reducing exhaust emissions) quantity). [0003] Because the luminous efficiency of LE...

AI Technical Summary

Problems solved by technology

[0003] Because the luminous efficiency of LEDs decreases with the increase of LED temperature, the heat dissipation of LEDs is very important, especially for high-power LEDs. Without good heat dissipation, it will greatly accelerate the light decay of LEDs and reduce the use of LEDs. longevity, a lot of heat buildup, and sometimes even breakdown the board
