The following is a brief description of the impact of the selection of three materials on lighting products. 1. The brightness of the LED light emitting diode light emitting diode is determined by the LED chip bare core brightness and the package shape of the lamp body, and its service life is determined by the working environment and quality of the LED chip. Here we must specifically explain that the LED chips used in LED lighting products now have standard sizes: red, yellow 12 mil, blue and green 14 mil, but they also have 8-10 mil chips. The brightness of chips of different sizes can be the same, but its lifetime is completely different, because the greater the overcharge of the chip per unit area, the shorter the lifetime is, which is the reason that the brightness of the same brightness LED is not the same. 2, PCB circuit board 3, the shell Lighting brand plate lighting decoration Aluminum Strip for Auto,Aluminum Braze Strip,Aluminum Strip for Radiator Fan Aluminum Engeering (Ji'nan) Company Ltd. , http://www.sdaluminumcoil.com
The circuit board as a light source carrier directly affects the lifetime and failure rate of the lamp. All electronic circuits of LED lighting products are on the PCB circuit board. Its material and processing technology will directly affect the quality and life of the product. Circuit board material is divided into full glass fiber, semi-glass fiber, cardboard three. The standard material of LED lighting products should be a full glass fiber double panel, such as the use of semi-glass fiber or cardboard single panel later welding quality and moisture, anti-aging ability and electrical properties will be greatly reduced.
The shell is used as the light mixing layer and protective layer of the lighting product, and also affects the effect and life of the lighting product. The engineering material currently used is generally PC (polycarbonate), and its anti-aging, anti-ultraviolet, and impact resistance effects are the best. Also useful PMMA (acrylic), its weather resistance is slightly poor, and more fragile brittle. The PC material itself is colorless, and different colors of PC tubes can be processed by adding different colorants as needed. The commonly used PC tube is transparent and milky white. The brightness of the transparent tube is higher than that of the milky white, but milk color mixing is superior to the transparent tube.
LED industry has been making rapid progress in the world recently, especially decorative lighting, is in full swing, is widely used in building outlines, bridges, squares and other municipal lighting projects, and hotels, KTV, hotels, playgrounds and other entertainment venues . The main components of the LED guardrail tube in LED lighting products are: LED light-emitting diodes, PCB circuit boards, and housings. These three kinds of materials constitute the main body of lighting products, and also basically determine the material quality of lighting products.
