High-power intelligent LED lamp rapid in heat dissipation

Abstract

The invention discloses a high-power intelligent LED lamp rapid in heat dissipation, and belongs to the field of LED lamps. The high-power intelligent LED lamp comprises an LED lamp device and a liquid cooling device. The LED lamp device comprises a completely-closed hollow lamp body, an upper LED lamp body and a lower LED lamp body. The lamp body is composed of a front platform portion and a rear cylinder portion which are communicated with each other. The front platform portion comprises an upper installation flat face and a lower installation flat face. The upper LED lamp body and the lower LED lamp body are arranged on the two installation flat faces respectively. The lamp body is a metal lamp body high in heat conductivity. The liquid cooling device comprises a water inlet pipe, a water outlet pipe, a water pumping motor, a liquid storage tank, a heat dissipation device and a fan, wherein one end of the water inlet pipe is connected with the water pumping motor which is located at the bottom of the liquid storage tank, the liquid storage tank is connected with the heat dissipation device, one end of the water outlet pipe is connected with the water inlet of the heat dissipation device, and a heat dissipation coiled pipe is arranged in the heat dissipation device. The LED lamp can replace an existing lamp bulb or can be used as a high-power lamp in narrow heat dissipation space without changing the structure of an existing vehicle lamp, and the LED lamp is rapid in heat dissipation, high in light intensity, capable of saving energy and environmentally friendly.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a high-power intelligent LED lamp with fast heat dissipation. Background technique [0002] LED has the advantages of fast response (10-6US level), high luminous efficiency (5-10 times that of ordinary light bulbs), energy saving, environmental protection, long life (100,000 hours), rich colors, and anti-vibration, etc. It has become the fourth-generation light source , but when used in car lights and narrow lamps and some super-high-power LEDs, junction temperature heat dissipation is the key issue for the life, effect and performance of headlights, and it is also a worldwide problem in the LED industry. As we all know, the temperature of the LED chip is too high (junction temperature Performance drops above 90°C, and it may be damaged if it exceeds 125°C) is the dead spot of LEDs. The light decay is serious, the performance changes sharply with the temperature, and the life is very short. Althoug...

As we all know, the temperature of the LED chip is too high (junction temperature Performance drops above 90°C, and it may be damaged if it exceeds 125°C) is the dead spot of LEDs. The light decay is serious, the performance changes sharply with temperature, and the life is very short. Although some manufacturers produce LED headlights for vehicles on the market, the brightness is generally not enough. , the light decay is serious, the service life is not long, and it is easy to be damaged. Some of them can’t even cover the dust cover.
