Use of new materials in LED lamps
In the LED field, cost and heat dissipation have always been the two major problems that beset the development and popularization of LED. It has been a development direction of LED technology to explore new raw materials to improve light efficiency and reduce cost.

1. Aluminum plastic bag
After combining the advantages and disadvantages of the heat dissipation performance of plastic and aluminum, the LED plastic-clad aluminum heat dissipation kit was developed and put on the market. This kind of heat dissipation material is wrapped in the outer plastic material, while the inner aluminum material is used for heat conduction. After combining the advantages and disadvantages of the two, the product has better performance, strong thermal conductivity and its cost has been controlled. In addition, the plastic itself is relatively easy to process and shape, so the shape and style of aluminum plastic package are rich, and meet the needs of different places.
Compared with aluminum, plastic aluminum heat dissipation has the advantage of high quality and low price, which can reduce the cost, meet the market demand, and meet the production demand of merchants, so as to increase the profit. In addition, this material is easy to shape and build, so it can be recycled, saving costs and protecting the environment.
2. Magnesium aluminum alloy
The main element is aluminum, and then mixed with a small amount of magnesium or other metal materials to strengthen its hardness, because of its thermal conductivity, high strength, low density, corrosion resistance, recyclable, good thermal conductivity, anti-electromagnetic radiation many advantages and become a new material. Magnesium aluminum alloy is applied in the shell and heat dissipation module of LED lamps, which can quickly dissipate the heat generated during the operation of LED lamps and extend the service life of lamps. The advantages of magnesium aluminum alloy in LED lamps are as follows:
(1) good heat dissipation
Magnesium aluminum alloy can effectively distribute heat from the inside to the outside. Magnesium aluminum alloy can be used on the shell and heat dissipation parts to make the electrical shell without heat dissipation holes.
(2) the light
In order to realize environmental protection, energy saving and emission reduction, the light fittings made of magnesium aluminum alloy profiles can not only effectively reduce the load bearing and reduce the load, but also reduce the additional injury to the maximum extent.
(3) better electromagnetic shielding performance
Used on LED lamps, can be effectively reduced

4. LED color management system and color rendering of light source
1.LED color management system
(1)RGB color mixing system, more and more rich and gorgeous colors can be achieved through color combination and superposition of LED of different colors. Various colors can be obtained through the change of red (R), green (G) and blue (B) color channels and their superposition among each other, and any color mixing can be achieved. At present, more color mixing methods are constantly appearing. RGBW color mixing can guarantee the brightness of white light and realize color mixing of any color at the same time. RGBA color mixing can provide more color mixing; There have even been five or seven more color blends, allowing for higher quality white light and richer colors.
(2) in the HsIc color system, H, s, I and c parameters are used to describe the color characteristics. H defines the color wavelength, which is called hue, and measures it with an Angle, ranging from 0° to 360°. The value is calculated in a counterclockwise direction from red, 0° for red, 120° for green and 240° for blue. Their complementary colors are: yellow 60°, cyan 180°, and magenta 300°; S represents the degree of depth of color, called saturation, which ranges from 0.0 to 1.0. The larger the value is, the more saturated the color will be. I represents intensity or brightness, with values ranging from 0(black) to 255(white). C is for color temperature, a physical quantity used to define the color of a light source. That is, a black body is heated to a temperature. The color of the light emitted by the black body is the same as the color of the light emitted by a light source. At the same time, the temperature heated by the black body is called the color temperature of the light source, or color temperature for short.
