[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

Embodiment Construction
[0026] In order to further illustrate the structure of the present invention, it is described as follows with reference to the accompanying drawings of the embodiments;
[0027] figure 1 , 2 Shown is one of the examples. The whirlwind heat-dissipating LED lamp of the present invention comprises a heat-dissipating and heat-conducting device, a heat-conducting sheet 9, an LED chip bulb 12 and its fixing part, and is characterized in that the fixing part is a tower-shaped lamp cap 1, and the heat-conducting sheet 9 is a light bulb 12 carrying an LED chip. Or the heat conduction device of LED chip patch 12a, this heat conduction sheet 9 is shaped as having several vertical elongated sheets on a horizontal sheet shape, and there is no horizontal connection sheet in the vertical elongated sheet, and on the top of heat conduction sheet 9, adopts no Hole or hole group 9a, the heat conduction sheet 9 and the LED lamp 12 are fixed in the lamp support plate seat 11 holes together, and ...

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...
