Problems solved by technology

[0004] As we all know, heat dissipation is one of the technical difficulties of LED lighting fixtures. Existing LED lighting fixtures mainly have two heat dissipation methods: active cooling and passive cooling: active cooling is like adding a radiator. Although the active cooling solution is highly praised, its production cost too high to be accepted by producers
Another passive heat dissipation method, if the structural design of the LED lighting fixture is unreasonable, when the heat accumulation reaches a certain level, it will interfere with the normal operation of the lamp, and even affect the life of the lamp
[0005] Passive heat dissipation means relying on the heat dissipation structure of the LED lamp itself to dissipate heat. Chinese Utility Model Patent Application No. CN201220731471 discloses an LED bulb lamp, which includes a lamp cap and a lamp body arranged on the lamp cap. The lamp body includes a heat dissipation The shell and the transparent lampshade installed on the heat dissipation shell, the outer surface of the heat dissipation shell is vertically provided with wave-shaped heat dissipation fins, the heat generated by the LED light source is conducted to the wave-shaped heat dissipation fins of the heat dissipation shell for heat dissipation, the patented structure only Set one cooling channel, the cooling effect is limited, not suitable for high-power LED lights

Abstract

The invention relates to an LED lamp with good heat dissipation effect and multiple paths to dissipate heat. The LED lamp comprises a lamp holder, a driving power source, an LED light source and a heat dissipation shell, wherein the lamp holder is installed on the heat dissipation shell and the LED light source and the driving power source are installed in the heat dissipation shell. The heat dissipation shell comprises an outer heat dissipation shell body, a heat dissipation connector and an inner heat dissipation shell body, wherein the outer heat dissipation shell body and the inner heat dissipation shell body are connected to the heat dissipation connector to form a cup body structure with a cavity interlayer. The LED light source is installed in the cavity formed by the outer heat dissipation shell body in an enclosure mode, the lower end of the inner heat dissipation shell body abuts against the LED light source, and the light-emitting component of the LED light source is located in the cavity formed by the inner heat dissipation shell body in an enclosure mode. The LED light source is connected with the outer heat dissipation shell body and the inner heat dissipation shell body and provided with the multiple heat dissipation paths, and therefore the heat of the LED light source can be dissipated faster, the heat dissipation efficiency can be improved, and the heat dissipation effect is good.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED lamp with good heat dissipation effect and multi-path heat dissipation. Background technique [0002] LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. Compared with ordinary lamps (incandescent lamps, etc.), LED lights have the advantages of energy saving, long life, good applicability, short response time, and environmental protection. [0003] Existing lighting fixtures mostly use tungsten filament bulbs, energy-saving lamps and LED lighting lamps. Due to the low electro-optical conversion efficiency of traditional tungsten filament lamps (about 5%), they are about to withdraw from the stage of history, and energy-saving lamps are in the production process. , because it must involve the use of toxic mercury elements when emitting light, a...
