Description

A kind of LED street light

technical field

The utility model relates to a lighting fixture, in particular to a high-power LED street lamp.

Background technique

With the emergence of the global energy crisis and the implementation of national energy conservation and emission reduction policies, energy conservation has become a national policy. Because LED lights have the advantages of small size, low heat generation, low power consumption, low-voltage low-current start-up, fast response, high-frequency operation, and long service life, the application of LED street lights is an inevitable trend of social development. Most of the existing high-power LED street lights include dozens of LED light-emitting diodes or more. The total heat generated by these LED light-emitting diodes is very large during operation. If the heat is not dissipated in time, it will have a great impact on its performance and life. Impact.

Utility model content

The purpose of the utility model is to provide a high-power LED street lamp with good heat dissipation performance.

The technical solution adopted by the utility model to solve the technical problem is: an LED street lamp, including an upper lampshade and a lower lampshade that are fastened to each other, an aluminum substrate is arranged on the lower lampshade, and a plurality of LEDs arranged in an array are fixed on the front of the aluminum substrate. A light-emitting diode, a heat-dissipating copper pipe is fixed on the back of the aluminum substrate, and a radiator is fixed on the heat-dissipating copper pipe.

Wherein, the heat sink is composed of multiple parallel aluminum plates.

In addition, both the side wall of the upper lampshade and the bottom of the lower lampshade are provided with exhaust holes.

The beneficial effects of the utility model are: since the heat dissipation copper tube is fixed on the back of the aluminum base plate, the heat dissipation copper tube is provided with a radiator and a heat sink, which can quickly transfer the heat emitted by the LED light-emitting diode, and effectively solve the heat dissipation technology of the high-power LED. Difficulties, so that the service life of LED street lights can be guaranteed.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Figure 1, an LED street lamp includes an upper lampshade 2 and a lower lampshade 1 that are interlocked with each other. The lower lampshade 1 is provided with an aluminum substrate 3, and a plurality of LED light-emitting diodes 4 arranged in an array are fixed on the front of the aluminum substrate 3. The back of the aluminum substrate 3 is fixed with a heat dissipation copper tube 5, and the heat dissipation copper tube 5 is fixed with a radiator 6. The radiator 6 is composed of a plurality of parallel aluminum plates. The length of the heat dissipation copper tube 5 is longer than that of the aluminum substrate 3, and the heat dissipation copper The two ends of the tube 5 located outside the aluminum substrate 3 are provided with a plurality of cooling fins 7. Since the back of the aluminum substrate 3 is fixed with a cooling copper tube 5, and the cooling copper tube 5 is provided with both a radiator 6 and a cooling fin 7, The heat emitted by the LED light-emitting diode 4 can be quickly transferred, effectively solving the heat dissipation technical problem of high-power LEDs, and ensuring the service life of the LED street lamps.

In addition, the side wall of the upper lampshade 2 and the bottom of the lower lampshade 1 are provided with exhaust holes 8. When the air in the lampshade is heated and expanded, cold air flows in from the exhaust holes 8 on the lower lampshade 1, and hot air flows in from the upper lampshade. 2 The exhaust hole 8 on the side wall flows out, so that the air continuously enters and flows out, and the heat is circulated to dissipate the heat in the lampshade efficiently and quickly.

What is described above is only the preferred embodiment of the present utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the premise of the inventive concept of the present invention, some deformations and improvements can also be made, and these all belong to Protection scope of the present utility model.
