Problems solved by technology

However, the heat dissipation effect of the existing heat dissipation structure has a certain linear law, which is a continuous and stable heat dissipation process. No matter how powerful the heat dissipation function of the radiator is, it cannot break through this linear law in a short time, so that the lamp instant cooling
When LED lamps work continuously for a long time or are overloaded, the heat dissipation of the radiator often reaches its limit and cannot maintain the temperature of the whole lamp. As the temperature continues to rise, it will have a great impact on the service life of LED lamps, even will be scrapped directly

Abstract

The invention provides an LED lamp. The LED lamp comprises a heat radiation outer shell, a light source plate and a heat radiator, wherein the heat radiation outer shell and the light source plate define a heat radiation cavity together, and the heat radiator is arranged in the heat radiation cavity. The LED lamp further comprises a heat driver arranged in the heat radiation cavity and a cooling device containing cooling liquid, wherein the cooling device is provided with a spraying opening used for spraying the cooling liquid, the spraying opening is provided with a plug valve, one end of theheat driver is connected with the heat radiator or the light source plate to sense temperature, the other end of the heat driver acts on the plug valve; the heat driver drives the plug valve to movethrough heated extension of the heat driver so that the plug valve can break away from the spraying opening; and the cooling liquid in the cooling device is sprayed into the heat radiation cavity fromthe spraying opening to carry out heat radiation.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to an LED lamp capable of instant cooling and rapidly reducing the temperature of the lamp when the heat of the lamp reaches a certain limit temperature. 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.), the emergence of LED lamps has the advantages of energy saving, long life, good applicability, short response time, and environmental protection. [0003] There are many ways to dissipate heat in existing LED lamps. For example, in the LED lamp with a radiator disclosed in the Chinese Utility Model Patent Application No. CN201220110438.1, the radiator is directly used for heat dissipation; or as the Chinese Utility Model Patent Application No. CN201620238798.
