Description

A kind of LED street light

Technical field:

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

Background technique:

As we all know, the lighting of public places such as roads and streets now mainly depends on street lamps. At present, the street lamp is mainly composed of a base fixed on the lamppost, a reflector and lighting source and other accessories. The lighting sources of street lamps mostly use high-power lighting sources such as high-pressure sodium lamps, high-pressure mercury lamps, and metal halide lamps. However, the disadvantages of these lighting sources are high power consumption, high temperature, short life, and difficulty in recycling. The energy-saving and environmental protection design concept advocated by the lighting industry.

Utility model content:

The purpose of the utility model is to provide an LED (Light Emitting Diode, Light Emitting Diode) street lamp with energy saving, environmental protection and long service life in view of the deficiencies in the prior art.

In order to achieve the above object, the technical solution adopted by the utility model is:

It includes a heat dissipation base, a hollow frame-shaped outer frame, and a transparent cover installed and fixed in the hollow area of the outer frame. The outer frame and the heat dissipation base are interlocked. A light board is fixed on the top, and an LED is fixed on the bottom of the light board.

Wherein, the LEDs are arranged in a matrix on the lamp board.

Wherein, a reflective sheet is provided under the lamp board, and through holes corresponding to the LEDs on the lamp board are opened on the reflective sheet.

Wherein, the reflective sheet is provided with a reflective baffle for reflecting light.

Wherein, a plurality of heat dissipation fins are formed on the heat dissipation base.

Wherein, a waterproof rubber ring is provided between the outer frame and the heat dissipation base.

Wherein, one side of the heat dissipation base is fixed with a support column for connecting with a lamp post.

The beneficial effects of the utility model are:

An LED street lamp provided by the utility model includes a heat dissipation base, a hollow frame-shaped outer frame, and a transparent cover installed and fixed in the hollow area of the outer frame. The outer frame and the heat dissipation base are interlocked. In the storage area, the top of the storage area is fixed with a lamp board, and the bottom of the lamp board is fixed with an LED. Since the LED with low power consumption and long service life is used as the lighting source, compared with the existing street lamps, the utility model It can save a lot of electric energy and has a long service life.

Fig. 1 is the exploded schematic view of the utility model;

Fig. 2 is the enlarged schematic diagram of place A in Fig. 1;

Fig. 3 is the enlarged schematic diagram of place B in Fig. 1;

FIG. 4 is an enlarged schematic view of point C in FIG. 1 .

Detailed ways:

The utility model will be further described below in conjunction with the accompanying drawings, see Figures 1 to 4, the utility model includes a heat dissipation base 1, a hollow frame-shaped outer frame 2, a transparent cover 3 installed and fixed in the hollow area of the outer frame 2, the outer The frame 2 and the heat dissipation base 1 are interlocked and fixed by screws. The bottom of the heat dissipation base 1 is provided with an accommodating area 11, the top of the accommodating area 11 is fixed with a lamp board 4, and the bottom end of the lamp board 4 is fixed with an LED 5 , the LEDs 5 are arranged in a matrix on the lamp panel 4 to form a light source with higher brightness. The LED5 with low power consumption and long service life is used as the lighting source, which can save a lot of electric energy and has a long service life. It should be noted that the LEDs 5 can also be arranged in other shapes on the lamp board 4 , and are not limited to the matrix type in this embodiment.

In this embodiment, a reflective sheet 6 is provided below the lamp panel 4, and a through hole 61 corresponding to the LED5 on the lamp panel 4 is provided on the reflective sheet 6. Each through hole 61 can place an LED 5, and on the reflective sheet 6 A reflective baffle 62 for reflecting light is provided to increase the illumination brightness of the street lamp.

In this embodiment, a plurality of heat dissipation fins 12 are formed on the heat dissipation base 1 to increase the heat dissipation area of the heat dissipation base 1 so as to dissipate the heat generated by the LED 5 in a timely manner.

In this embodiment, a waterproof rubber ring 7 is provided between the outer frame 2 and the heat dissipation base 1 to prevent rainwater from entering the gap between the outer frame 2 and the heat dissipation base 1 and damaging the components inside the street lamp.

One side of the heat dissipation base 1 in this embodiment is fixed with a support column 8 for connecting with the lamp post, so that the heat dissipation base 1 can be firmly fixed on the lamp post. Of course, the support column 8 can be fixed on the lamp post in an adjustable manner. to adjust the height of the street light.

Of course, the above are only preferred embodiments of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the utility model patent application are included in the utility model patent application within range.
