Problems solved by technology

[0002] The LED itself of the existing LED light bar is a photoelectric device, and a large amount of electric energy will be converted into heat energy during the working process, which makes the temperature of the LED light bar rise, the heat dissipation effect is poor, and the LED chip is easily damaged, which shortens the life of the light bar. Service life; at the same time, the effect of astigmatism is not good

Embodiment Construction

[0015] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0016] like figure 1 and 2 As shown, an LED light bar includes a circuit substrate 1, a heat insulating material layer 2, a micro fan 3, a light bar 4 and a diffuser cover 5; Among them, the heat insulation material layer 2 is one of Weinai heat insulation hard felt and nano base heat insulation soft felt. The heat insulating material layer 2 can prevent the heat generated by the light bar 4 from being transferred to the circuit substrate 1 , causing the circuit substrate 1 to be burned.

[0017] The miniature heat dissipation fan 3 is located on the heat insulating material layer 2, and there are multiple heat dissipation miniature fans 3. At the same time of lighting, the heat dissipation miniature fan 3 starts...

Abstract

The invention relates to an LED light bar which comprises a circuit substrate, a thermal insulation material layer, a minitype cooling fan, a light bar and a light diffusing cover, wherein the thermal insulation material layer is arranged between the circuit substrate and the light bar; the minitype cooling fan is positioned on the thermal insulation material layer; the light diffusing cover is arranged at the lower end of the light bar; two bending angles A and B are positioned on two sides of the light diffusing cover; the bending angle A close to the light bar is 120 degrees; and the bending angle B far away from the light bar is 140 degrees. The LED light bar is provided with the minitype cooling fan to cool the light bar, so that the service life of the LED light bar can be prolonged; and in addition, the light diffusing cover is arranged to increase the light diffusing effect of the LED light bar by multiple times.

Description

technical field [0001] The invention relates to the field of lamps, in particular to an LED light bar. Background technique [0002] The LED itself of the existing LED light bar is a photoelectric device, and a large amount of electric energy will be converted into heat energy during the working process, which makes the temperature of the LED light bar rise, the heat dissipation effect is poor, and the LED chip is easily damaged, which shortens the life of the light bar. Service life; at the same time, the effect of astigmatism is not good. Contents of the invention [0003] In order to solve the above problems, the technical problem to be solved by the present invention is to provide an LED light bar. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an LED light bar, including a circuit substrate, a heat insulating material layer, a miniature heat dissipation fan, a light bar, and a diffuser cover; B...
