Description

New high power LED street lamp

technical field

The utility model relates to the field of street lamps, in particular to a novel high-power LED street lamp.

Background technique

Road lighting is an important part of urban lighting. Traditional street lights often use high-pressure sodium lamps to emit light at 360 degrees. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between energy supply and demand in my country has become increasingly prominent, and there has been a serious shortage of power supply. Energy conservation is an urgent problem to be solved. Therefore, the development of new high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lamps is of great significance to energy-saving urban lighting.

Road lighting is closely related to people's production and life. With the acceleration of urbanization in our country, LED street lights are gradually becoming more and more popular due to their advantages such as directional light emission, low power consumption, good driving characteristics, fast response speed, high earthquake resistance, long service life, and environmental protection. Entering people's field of vision, becoming the world's most powerful new generation of energy-saving light sources that can replace traditional light sources. Therefore, LED street lights will become the best choice for energy-saving transformation of road lighting.

In order to solve the above problems, the utility model proposes a new type of high-power LED street lamp, which is simple in design, easy to install and use, low in cost, good in heat dissipation, good in insulation, good in ventilation, and energy saving.

In order to achieve the above-mentioned purpose of the invention, the utility model proposes the following technical solutions:

A new type of high-power LED street lamp, which includes a housing, a driving power supply, a lightning protector, and an LED lamp group. The housing includes an upper housing and a lower housing. The upper housing and the lower housing are fastened together. There is a circular hole at the rear end of the shell, half a circular hole is formed on the upper shell and the lower shell respectively, the front ends of the upper shell and the lower shell are hinged together, and the upper shell and the lower shell are installed near the hinged position. Folding support, the middle position of the upper shell and the lower shell is connected together by a buckle, there are a number of ventilation holes on the top of the upper shell, and a semicircular positioning groove is designed on the side of the rear end of the lower shell close to the semicircular hole. The upper end of the circular positioning groove is equipped with a pressure ring, and there are two lamp head holes in the front end of the lower shell. The driving power supply and the lightning protection device are installed together near the inner side of the semicircular positioning groove. In the lamp head hole inside the housing.

The LED lamp group includes an LED lamp board and a heat dissipation board group. The LED light bulb is installed in the LED lamp board and installed in a fully sealed manner. Four heat radiation board groups are installed on the rear side of the LED lamp board.

The driving power supply, the lightning protector and the LED lamp group are connected together through a cable, and the cable connection is connected together in a fully sealed plug-in manner.

The LED lamp group has two groups, one group is installed in the lamp holder hole in the middle of the lower casing, the other group is installed in the lamp holder hole at the front end of the lower casing, and the other group is installed near the front end of the LED lamp group. There are some ventilation holes on the side plate.

The utility model has the advantages of simple design, convenient and fast installation, good air permeability, good heat dissipation performance, high waterproof performance, good insulation performance, low manufacturing cost, low power and high sensitivity up to 15 meters, which greatly saves energy. The driving power supply, lightning protector and LED lamp group of this device are all made of waterproof, and the cable connection is fully sealed and plugged, which has good waterproof performance. Bad performance problem.
