Description

A kind of LED street light

technical field

The utility model relates to the technical field of LED lamps, in particular to an LED street lamp.

Background technique

LED lights have become a large category in the lighting industry, and because of their energy-saving and stable characteristics, they have been more and more applied to street lights. Most of the existing LED street lamps are improved on the basis of the original street lamps. Therefore, the power supply is generally buried under the street lamp base, and the light source is installed in the lamp housing, which is fixed on the upper end of the street lamp pole. It is not difficult to see that in this prior art, a long wire needs to be set between the light source and the power supply, which not only increases the internal consumption of electric energy in the wire, but also increases the cost of wire installation. When the sealing of the base of the power supply is deteriorated, there will be leakage and short circuit phenomenon due to the infiltration of water in the road area.

Contents of the invention

The technical problem to be solved by the utility model is: to provide an LED street lamp, which sets the light source and the power supply together in the lampshade, so the wire between the light source and the power supply is short, and it is also convenient for the operator to check and repair the light source and the power supply at the same time. Avoid the impact of road surface water on street lamps.

The technical scheme adopted by the utility model is to provide an LED street lamp, which includes a front lampshade and a rear lampshade, and the front lampshade and the rear lampshade are surrounded to form a lamp housing with an inner cavity, which is characterized in that: the lamp housing is arranged at intervals There is a light source and a power supply. The light source is fixed on the front lampshade, and the front of the light source is exposed outside the lamp housing. The front lampshade is provided with a channel for the front of the light source to be exposed outside the lamp housing. There are several heat dissipation strips on the back of the inside, and the power supply is electrically connected to the light source through wires;

One end of the front lampshade is hinged to the rear lampshade, and a plurality of buckles are provided on the outer wall near the other end of the front lampshade for engaging with the rear lampshade. When the front lampshade and the rear lampshade are fastened, the front lampshade and the rear lampshade deviate from the hinge. There is a mounting hole at the other end, which is used for inserting the mounting rod on the street lamp holder into the lamp housing. There are multiple clamps near the mounting hole in the lamp housing. The two ends of the clamp are connected with the front The lampshade is fastened with threads, and a fastening space for tightening the mounting rod is formed between the clamp and the front lampshade.

A plurality of heat dissipation through holes are provided at the position of the near light source on the front lampshade, and all heat dissipation through holes are arranged along the circumferential direction of the light source.

An annular groove is provided on the front lampshade, and the light source and the heat dissipation through hole are respectively arranged on the front lampshade and are located near the position of the annular groove, and a desiccant is placed in the annular groove, and the desiccant meets water. After discoloration.

The front light cover is provided with a mounting plate, and the power supply is detachably mounted on the mounting plate.

After adopting the above structure, compared with the prior art, the LED street lamp of the present utility model has the following advantages: firstly, both the light source and the power supply are placed in the lamp housing, so the wire between the light source and the power supply is short, and the internal friction in the wire transmission process At the same time, it reduces the setting of wires and saves costs. Secondly, it is convenient for operators to overhaul at one time. Finally, the power supply is installed in the lampshade on the street light pole to avoid the leakage problem caused by road water, and the product has good stability.
