High-power LED (light emitting diode) spotlight and production process thereof

Abstract

The invention discloses a high-power LED (light emitting diode) spotlight and a production process. The high-power LED spotlight has the advantages of simple structure, reasonable structural design and beautiful appearance. The high-power LED spotlight comprises an outer shell, wherein a group of bilaterally symmetrical opening holes are arranged on the outer shell, the interior of the outer shell is provided with a heat dissipation module, the heat dissipation module comprises a heat pipe and a plurality of cooling fins, a bottom plate is arranged below the heat dissipation module, a light source is pasted on the bottom plate, a lens is arranged below the bottom plate, a power supply shell is arranged above the outer shell, and a bottom cover is arranged below the outer shell. The LED spot light has a good heat dissipation effect and is convenient to install and maintain, the production process can be conveniently realized, the heat dissipation mode adopts an active convection mode instead of the previous natural convection mode, the temperature of a lamp body cannot rise high after the spotlight illuminates for a long time, the light attenuation ratio can be smaller, the service life of the spotlight can be prolonged, the lighting effect can be improved, the irradiating light is far and the use cost is low.

Description

technical field [0001] The invention relates to LED spotlight lighting and its technology, in particular to a high-power LED spotlight and its production technology. Background technique [0002] Most of the spotlights in the past were halogen lamps and mercury lamps. These two lamps had a relatively limited lifespan. If they were used for a long time, they would even explode due to high temperature, posing safety hazards. Therefore, LED lamps with longer lifespan, safety and reliability began to gradually replace traditional lamps. Halogen lamps and mercury lamps, but due to the high power of LED spotlights, the characteristics of LED itself and the limitation of manufacturing process, how to improve the heat dissipation power of LED spotlights has become a new technical problem. With the increase of the power of LED lamps, the calorific value is greatly increased. Even if the volume of the radiator is continuously increased, the heat dissipation efficiency will be lower a...

AI Technical Summary

Problems solved by technology

When the LED emits light, in the process of converting electrical energy into light energy, the LED will generate some heat. If the heat cannot be fully dissipated, the internal temperature of the LED will rise, which will lead to a decrease in the luminous efficiency of the LED. If the internal temperature of the LED rises too high, it may Make the LED invalid, it is difficult to guarantee the expected service life of the LED

[0003] Due to the design of the LED lamp structure, good heat dissipation is not achieved, resulting in a large light attenuation rate, which affects the service life of the lamp. High-power LED spotlights must not only solve the heat dissipation problem, but also be limited by the size and volume of the lamp. , but also take into account the light distribution requirements of its use occasions, therefore, the rational design of its structure is particularly important

[0004] Since LED spotlights are mostly used for decoration and clothing industry, many methods are to add a multi-eye lens outside a single 1W LED lamp, for example, 18 lenses are used for 18W, so the light effect is not comparable to traditional light.
