Description

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:

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, a transparent cover installed and fixed in the hollow area of the outer frame, a power supply circuit board, and a lamp board. The bottom of the heat dissipation base is provided with an accommodation area, and the accommodation area is divided into The left accommodating area for placing the power supply circuit board and the right accommodating area for placing the light board, the bottom end of the light board is fixed with LEDs, the outer frame is fastened and fixed at the opening of the right accommodating area, the left accommodating area The opening of the setting area is buckled and fixed with a power cover.

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

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

Wherein, a waterproof rubber ring matching the opening of the right accommodation area 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, a transparent cover installed and fixed in the hollow area of the outer frame, a power supply circuit board, and a lamp board. The bottom of the heat dissipation base is provided with an accommodation area. The accommodating area is divided into a left accommodating area for placing the power supply circuit board and a right accommodating area for placing the lamp board. The bottom end of the lamp board is fixed with an LED, and the outer frame is buckled and fixed on the right accommodating area. The opening of the storage area and the opening of the left storage area are fastened and fixed with a power supply cover. 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 can save a lot of energy. energy and has a long service life.

Fig. 3 is the exploded schematic view of the utility model;

FIG. 4 is an enlarged schematic view of B in FIG. 3 .

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, and a power supply circuit board 4. The lamp board 5, the bottom of the heat dissipation base 1 is provided with a storage area, and the storage area is divided into a left storage area 11 for placing the power circuit board 4 and a right storage area for placing the lamp board 5 The bottom end of the lamp board 5 is fixed with LED6, the outer frame 2 is buckled and fixed at the opening of the right accommodation area 12, and the opening of the left accommodation area 11 is buckled and fixed with the power supply cover 7. LED6 is arranged on the lamp panel 5 in a matrix to form a light source with higher brightness. The LED6 with low cost and long service life is used as a lighting source, which can save a lot of electric energy and has a long service life. It should be noted that the LEDs 6 can also be arranged in other shapes on the lamp board 5, and are not limited to the matrix type in this embodiment.

In this embodiment, a plurality of heat dissipation fins 13 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 6 in a timely manner.

In this embodiment, a waterproof rubber ring 8 matching the opening of the right accommodation area 12 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 inside of the street lamp. parts.

One side of the heat dissipation base 1 in this embodiment is fixed with a support column 9 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 9 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.
