Cyclone heat dissipation led lamps

Abstract

Previously, the heat radiation problem of a high-power LED chip is the focus of a technology. A convection mode is mostly adopted, the upper portions of LED lamps are respectively provided with a large cooling fin made of aluminum alloy in a pressure casting mode, the structure is heavy, replacement and maintenance are inconvenient, most of the cooling fins cannot achieve the cooling effect when temperature is high, light attenuation is accelerated, and the service life of the LED lamps is shortened. A whirlwind type heat radiation LED lamp is mainly composed of heat conducting fins, an LED lamp body and LED patches, the physical phenomenon in hydromechanics is utilized, a plurality of air channels within a circumference are divided into the vortex effect which has an angle and generates rotary superposition under the action of a fan, slight fan active convection is utilized, the flowing speed of gas in the narrow heat conducting fin air channels is greatly improved, the super-strong heat radiation effect is achieved, the temperature of an LED chip is greatly reduced, light attenuation is greatly reduced, the service life of the LED lamp body is prolonged, indoor and outdoor lighting lamps and luminaires for industrial use can be replaced easily through a built-in driver, the LED lamp is as light, convenient to operate and fast as a common bulb, intelligent control is utilized, the two are combined alternately, energy is saved, the structural life of the lamp is prolonged, and the method is ingenious, simple and scientific.

Description

technical field [0001] The invention belongs to LED lamps. Background technique [0002] In the previous high-power LED lighting fixtures, the heat dissipation of the chip is a technical focus. If the heat dissipation is not good, it will directly affect the life of the LED. If it is light, it will accelerate the light decay and shorten the life of the LED lamp, and if it is serious, it will burn the chip and the LED bulb. Therefore, there is a large aluminum alloy die-casting heat sink on the upper part of the LED lamp, which cools down by heat conduction, convection and exchange in the atmosphere. The greater the power of the LED, the larger the heat dissipation "hat", the larger the area of ​​the heat sink, and the product will become very bulky. For this reason, the driving mode of the existing industrial and mining lamps is also a split type. The disadvantage is that it is very difficult to replace or repair if it is broken. Inconvenient, due to the consumption of mate...

Problems solved by technology

[0002] In the previous high-power LED lighting fixtures, the problem of heat dissipation of the chip is a technical focus. If the heat dissipation is not good, it will directly affect the life of the LED. If it is light, it will accelerate the light decay and shorten the life of the LED lamp. If it is serious, it will burn the chip and the LED bulb.

Due to its bulkiness, its installation and fixing methods mostly use clamps and hanging brackets to support it, which is inconvenient to use the lamp head to hang
