Description

High Brightness LED Cover Light

【Technical field】

The utility model relates to a high-brightness LED cover lamp.

【Background technique】

LED (Light Emitting Diode) is a solid-state semiconductor device that can directly convert electricity into light. Heat dissipation is a major factor affecting the lighting intensity of LED lamps. LED lamps are 80% more energy efficient than traditional incandescent lamps. , but its LED components and driver circuit have a large amount of heat dissipation. If the heat is not properly discharged, the luminosity and life of the LED lamp will drop sharply; the light-emitting unit of the LED bulb in the prior art, the radiator is installed in the lamp body In terms of heat dissipation, the heat dissipation space is small, the material is uneven, the heat dissipation is uneven, the light collection is poor, and the brightness is not enough.

Therefore, I developed a high-brightness LED cover lamp.

【Content of utility model】

The technical problem to be solved by the purpose of this utility model is to provide a high-brightness LED cover lamp, which has the advantages of simple structure, easy manufacture, high brightness, elegant appearance, and good heat conduction and heat dissipation performance.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a high-brightness LED cover lamp, which is characterized in that it includes a lamp body, and a heat dissipation device is installed on the lamp body.

A light guide cover, the lamp head body is installed on the outer top of the light guide cover, the light guide cover has a reflective inner wall layer, and the light guide cover has an inner cavity with an open opening;

An LED lamp board is installed at the bottom of the inner cavity, and the heat dissipation device is used to dissipate the heat generated by the LED lamp board.

Preferably, the LED light board is circular, and a plurality of LED light sources are arranged on it.

Preferably, the light guide cover is in the shape of a pot lid or a trumpet or a part of a spherical shape.

Preferably, the lamp head body is detachably assembled on the light guide cover.

Beneficial effect:

The utility model adopts the above-mentioned technical scheme, and has the advantages of simple structure, easy manufacture, good light collection, high brightness, elegant appearance, and good heat conduction and heat dissipation performance.

【Description of drawings】

Fig. 1 is the structural representation of the high-brightness LED shade lamp in the embodiment;

Fig. 2 is a schematic view of the structure of the high-brightness LED cover lamp in another viewing angle.

【Detailed ways】

Check out Figures 1 and 2. In the following, the specific implementation of the utility model will be further described in combination with the accompanying drawings of the specification, so that the technical solution and beneficial effects of the utility model will be clearer and more definite.

Please refer to Fig. 1-2, the utility model provides a high-brightness LED cover lamp 100, which includes a lamp body 110, and a heat dissipation device 120 is installed on the lamp body 110,

A light guide cover 130, the outer top of the light guide cover 130 is equipped with the lamp head body 110, the light guide cover 130 has a reflective inner wall layer 131, and the reflective inner wall layer 132 can be formed by electroplating or spraying reflective paint. The photomask 130 has an inner cavity 132 with an open opening;

An LED lamp board 140 is installed at the bottom of the inner cavity 132 , and the heat dissipation device 120 is used to dissipate heat generated by the LED lamp board 120 . There is no barrier to heat transfer, good heat dissipation, and the position above the light guide cover 130 of the heat dissipation device 120 has a large space, which is convenient for airflow to take away heat.

The LED lamp board 140 is circular, and a plurality of LED light sources are arranged on it. The light guide cover is pot-shaped or trumpet-shaped or partially spherical. The reflective effect is more uniform and effectively provides brightness.

Preferably, the lamp head body is detachably assembled on the light guide cover.

Through the description of the above structure and principle, those skilled in the art should understand that the utility model is not limited to the above-mentioned specific implementation, and the improvement and replacement of the technology known in the art on the basis of the utility model all fall within the scope of the utility model. A new type of protection.
