Description

An air-circulating LED lamp

technical field

The utility model relates to the technical field of LED heat dissipation, in particular to an air circulation type LED lamp.

Background technique

Due to the advantages of power saving, low energy consumption, high luminous efficiency, long service life and durability, light-emitting diodes (LEDs) have been widely used in various fields, such as traffic signs, large advertising billboards, vehicles, flashlights , Indoor or outdoor lighting and other equipment.

However, since the LED is a point light source, the heat source generated by it is concentrated, and as the power of the LED lamp increases, the heat generated by the LED cannot be dissipated effectively, which reduces the luminous efficiency, quality and service life of the LED.

Contents of the invention

The purpose of this utility model is to aim at the defects and deficiencies of the prior art, and to provide an air circulation LED lamp with simple structure, reasonable design and convenient use. The air circulation effect can be increased, and it has the characteristics of convenient use, simple operation, good practicability, low cost and the like.

For realizing above-mentioned object, the technical scheme that the utility model adopts is:

An air circulation LED lamp according to the utility model comprises a base, the lower end of the base is connected with a bracket, the bracket is in a U-shaped structure, a filter screen is connected between the base and the bracket, and the lower end of the bracket is set There is a heat dissipation plate, the lower end of the heat dissipation plate is provided with a lampshade, the center of the lampshade is provided with a lamp bead, the lamp bead and the edge of the lampshade are connected with a reflector, the base and the lampshade are connected with a central axis, and the central axis A fan is arranged at the bracket.

The heat dissipation plate adopts a metal plate with a foam structure, and the metal plate with a foam structure has good thermal conductivity, and at the same time, the heat dissipation plate adopts a foam with good air circulation.

The bottom of the support is provided with a microporous plate, and the support with a microporous plate structure has a good ventilation effect and good circulation.

After adopting the above structure, the beneficial effects of the utility model are as follows: the utility model adopts a fan and a filter screen arranged at the lower end of the base, which can increase the air circulation effect through the fan; adopts the central axis connected up and down, which has a good connection effect, and at the same time It has a good line connection function; the heat dissipation plate is arranged on the upper end of the lampshade, which has a good heat dissipation effect and can reduce the heat of the lamp bead in time; the setting of the reflector and the lampshade can have a certain heat reflection effect and ensure the service life of the lampshade; And it has the characteristics of convenient use, simple operation, good practicability and low cost.
