Description

A kind of LED downlight

technical field

The utility model relates to an LED downlight.

Background technique

Due to the large power consumption of traditional downlights, short life, frequent replacement of light sources, and ultraviolet radiation, which is not conducive to environmental protection, etc., current downlights have been changed to illuminants of other structures. Especially the LED luminous body has the advantages of power saving, long life, etc., and now there are more and more LED downlights using LED luminous bodies. However, the existing LED downlights have the following defects: 1. The focus is serious, the light is dazzling, and many lighting places are not suitable, which limits the development of LED downlights; 2. The structure is too complicated, the assembly is troublesome, and the cost is high; 3. , The heat dissipation effect is poor, which greatly shortens the life of the LED fluorescent tube.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide an LED downlight with simple structure, convenient installation and use, astigmatism and anti-glare effects.

In order to achieve the above object, the utility model adopts the following scheme:

An LED downlight, including a lamp housing, is characterized in that: an aluminum substrate is arranged in the lamp housing, a plurality of LED illuminants are arranged on the circuit board, and the inner wall of the lamp housing is trumpet-shaped , A diffused acrylic light-transmitting sheet is arranged on the lamp housing, and a driver box is connected to both sides of the lamp housing through brackets.

The above-mentioned LED downlight is characterized in that a plurality of sheet-like cooling fins are arranged on the periphery of the lamp housing.

The above-mentioned LED downlight is characterized in that an annular step is provided on one end of the lamp housing, and the diffused acrylic light-transmitting sheet is arranged in the annular step, and passes through a plurality of "7" The word card is fixed on the lamp housing.

The above-mentioned LED downlight is characterized in that the left and right spring fasteners and the front and rear shrapnel can make the whole lamp body more firmly fixed on the ceiling on the lamp housing.

The above-mentioned LED downlight is characterized in that the driver box includes a front cover and a rear cover, and a driver is arranged in the driver box.

In summary, the utility model has the beneficial effects relative to the prior art as follows:

1. The utility model adopts the combination of aluminum alloy lamp housing, diffused acrylic sheet and small-volume LED lamp beads, and replaces the existing light source with LED luminous body, which is environmentally friendly, energy-saving and has a long life;

2. The diffused acrylic sheet is designed with a diffused matte surface, which is helpful for astigmatism and anti-glare effects, making the light softer;

3. There is a flaky heat sink on the periphery of the aluminum alloy lamp housing, which has a better heat dissipation effect;

4. It can directly replace the traditional downlight, as long as the old downlight is removed without changing the hole position of the ceiling, it can directly replace the traditional downlight;

5. In addition, the utility model also has the characteristics of power saving, long life, no ultraviolet radiation, and soft light.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

An LED downlight as shown in Figures 1 to 4, includes an aluminum alloy lamp housing 1, an aluminum substrate 2 is arranged inside the lamp housing 1, and a plurality of LED illuminants are arranged on the aluminum substrate 2 3. The inner wall of the lamp housing 1 is trumpet-shaped, which is equivalent to the function of a reflector. The bottom of the lamp housing 1 is flat and is used to fix the LED illuminant 3. The LED illuminant 3 is composed of multiple LED lamp beads, which contributes to the light The emission is more uniform, and the diffused acrylic light-transmitting sheet 4 is arranged on the lamp housing 1. The diffused acrylic sheet adopts a diffused matte design, which is helpful for astigmatism and anti-glare effects, and makes the light softer. A driver box 6 is connected to both sides of the lamp housing 1 through brackets 5 . The driver box 6 includes a front cover 61 and a rear cover 62 , and a driver is arranged inside the driver box 6 . The driver box 6 is arranged outside the lamp housing 1, which effectively reduces the heat dissipation of the lamp body.

In the utility model, a plurality of sheet-like cooling fins 7 are arranged on the periphery of the lamp housing 1 . Make the whole lamp body have a good heat dissipation effect.

In the utility model, an annular step 8 is arranged on one end of the lamp housing 1, and the diffused acrylic light-transmitting sheet 4 is arranged in the annular step 9, and is fixed on the On the lamp housing 1. In the utility model, the left and right spring fasteners 10, 11 and the front and rear shrapnel 12, 13 can make the whole lamp body more firmly fixed on the ceiling on the lamp housing 1.
