Anti-shock reinforced heat dissipation energy-saving LED light bar

Abstract

The invention discloses an anti-shock reinforced heat dissipation energy-saving LED light bar comprising a bar-shaped circuit board and a row of LED lights arranged on the bar-shaped circuit board. A heat dissipation layer is arranged at the bottom of a glass fiber board layer. Two copper plate electric leads are arranged on the upper surface of the glass fiber board layer in a spaced mode. The LED lights comprise light feet connected with the two copper plate electric leads correspondingly. Elastic heat conduction columns are arranged between the bottoms of the LED lights and the top face of the glass fiber board layer. Ventilation heat dissipation pipes located below the copper plate electric leads correspondingly are arranged in the glass fiber board layer. Arc-shaped lampshades are arranged above the LED lights. Clamping rings corresponding to the LED lights are arranged in the arc-shaped lampshades so as to limit the LED lights. In this way, according to the anti-shock reinforced heat dissipation energy-saving LED light bar, the tops of the LED lights are limited by the clamping rings, the bottoms of the LED lights are supported by the elastic heat conduction columns, anti-shock performance is good, the ventilation heat dissipation pipes can conduct ventilation forcibly so as to bring away heat of the glass fiber board layer, and heat dissipation of the copper plate electric leads is reinforced.

Description

Technical field [0001] The invention relates to the field of LED light bars, in particular to a heat-dissipating and energy-saving LED light bar with enhanced seismic resistance. Background technique [0002] LED lamps have good energy-saving properties, long lifespan, small size, environmental protection and easy recycling, so they have been vigorously developed in recent years. Due to the short response time and rapid response of LED lights, they are widely used in the backlight field of liquid crystal displays, which promotes the development and popularization of liquid crystal displays. [0003] With the advancement of liquid crystal display technology and the upgrading demand of the market, the current liquid crystal display is developing in a larger and thinner direction. Although the calorific value of LED lamps is less than that of ordinary incandescent lamps, there are still problems in heat dissipation in the thin and light chassis space, especially for some car navigati...

AI Technical Summary

Problems solved by technology

Although the calorific value of LED lamps is smaller than that of ordinary incandescent lamps, there are still problems with heat dissipation in the light and thin casing space, especially for some displays used in car navigation, the operating environment temperature is higher, and the vibration is large, so shock absorption needs to be strengthened
