LED lamp with high heat dissipation performance and long service life

Abstract

The invention relates to the technical field of lamp heat dissipation, and discloses an LED lamp with the high heat dissipation performance and the long service life. The LED lamp comprises a bottom plate; the left side and the right side of the bottom plate are provided with mounting holes; the middle of the upper surface of the bottom plate is provided with a stand column; the right side of theupper end of the stand column is provided with a connecting pipe; the right side of the connecting pipe is connected with a lamp cap; the lower surface of the lamp cap is provided with a supporting plate; the lower surface of the supporting plate is provided with an LED bulb; the left side wall of the bottom of the stand column is provided with an air inlet; the bottom of the air inlet is providedwith a rotating seat; the rotating seat is rotationally connected with a rotating plate; and a driving motor is arranged on the right side wall of the bottom of the stand column. According to the LEDlamp with the high heat dissipation performance and the long service life, a fan is arranged at the bottom of the stand column, so that cold air which is relatively close to the ground is blown to the lamp cap for cooling the lamp cap; the fan can provide the relatively large air volume, so that the heat dissipation effect is improved; and by combining with the rotating plate that can freely rotate, water can be effectively prevented from entering the lamp on rainy days and the service life of the whole lamp is prolonged.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of lamps, in particular to an LED lamp with high heat dissipation and long service life. Background technique [0002] LED (Light Emitting Diode) is called the fourth-generation lighting source, which has many advantages such as energy saving, environmental protection, and long service life, and is widely used in various display, lighting and other fields. With the continuous development of the lighting industry, the demand for high-power LEDs is increasing. However, since the electro-optical conversion efficiency of LED is generally only 20-30%, the remaining 70-80% of the electric energy is finally converted into heat energy, and if this part of heat energy cannot be discharged in time, it will have a negative impact on the stability, reliability and service life of the LED. huge influence. [0003] Chinese patent (notification number: CN208652408U) discloses a high-efficiency heat di...

However, since the electro-optical conversion efficiency of LED is generally only 20-30%, the remaining 70-80% of the electric energy is finally converted into heat energy, and if this part of heat energy cannot be discharged in time, it will have a negative impact on the stability, reliability and service life of the LED. huge influence

[0003] Chinese patent (notification number: CN208652408U) discloses a high-efficiency heat dissipation street lamp lamp holder, including lamp holder body, pillar, cover plate, solar panel, first telescopic rod, second telescopic rod, limit plate, threaded hole, heat dissipation port, Protective grille, heat collector plate, heat dissipation aluminum plate, heat dissipation fins and battery. The top of the lamp head body is provided with a heat dissipation port. The structure of the device is scientific and reasonable, and it is safe and convenient to use. The heat is collected by the heat collector plate, and the heat collector plate absorbs the heat Transfer to the heat dissipation aluminum plate, the heat in the heat dissipation aluminum plate accelerates the dissipation speed through the heat dissipation fins, the rotation of the rotating motor drives the fan blades to rotate through the transmission shaft, the fan blades accelerate the air circulation inside the lamp body, and accelerate heat dissipation, and the protective grille prevents foreign objects from entering the lamp body Inside, the filter screen filters the dust in the outside air to prevent dust from entering the lamp body and causing damage to the electrical components inside the lamp body. The rainy weather cover prevents rainwater from entering the lamp body. Heat dissipation, can play a certain heat dissipation effect, but the effect is poor, so the device needs to be improved
