Lighting technology

 

Semiconductor lighting, also known as solid-state lighting, refers to the lighting with solid-state light-emitting devices as light source, including light-emitting diodes (LED) and organic light-emitting diodes (OLEDs). It has the characteristics of low power consumption, long life, rich color, vibration resistance and strong controllability. Since the 1990s, semiconductor lighting technology has made continuous breakthroughs and its application fields have been expanding day by day. The technology in the field of indication and display is basically mature and widely used; the technology in special fields such as medical treatment and agriculture is in the ascendant. In recent years, semiconductor lighting industry has developed rapidly, and foreign countries and Taiwan have strong advantages in different fields. With the acceleration of industrial structure adjustment and development mode transformation in China, semiconductor lighting energy-saving industry as an important measure of energy conservation and emission reduction has ushered in a new development opportunity period.

 

Advantages of LED light source:

 

    -High energy saving: energy saving without pollution means environmental protection. DC drive, ultra-low power consumption (single tube 0.03-0.06 w) electro-optical power conversion close to 100%, the same lighting effect than the traditional light source energy saving more than 80%.
-Long life: LED light source is called longevity lamp, which means never extinguished lamp. Solid state cold light source is packaged with epoxy resin, and there is no loose part in the lamp body. There are no defects such as easy burning of filament light, thermal deposition and light fading. The service life of the lamp can reach 60000 to 100000 hours, which is more than 10 times longer than that of the traditional light source.
-Changeable and illusory: LED light source can use the principle of red, green and basket three primary colors, and make the three colors have 256 levels of gray level under the control of computer technology and mix them arbitrarily, which can produce 256 × 256 × 256 = 16777216 colors, form the combination of different light and color, and realize rich and colorful dynamic change effect and various images.
    -Environmental protection: it has better environmental protection benefits. There is no ultraviolet and infrared ray in the spectrum, neither heat nor radiation. The glare is small. Moreover, the waste can be recycled, no pollution, no mercury. The cold light source can be safely touched. It is a typical green lighting source.

Process control

 

Xi'an gemei metal materials Co. Ltd. production began to control from raw materials, continuous selection of quality raw materials, product stability and consistency is very prominent. For different grades of raw materials, marking, marking the lot number. And for each batch of raw materials sampling inspection, inspection and filing. Ensure that the finished product has traceability, continuous improvement of product quality. Xi'an gemei metal materials Co. Ltd. production milling process control is very accurate, with several large mixing machine and vibration platform, ensure milling and mixing process of materials can be fully stirred, to ensure the consistency of the internal organization of product. Xi'an gemei metal materials Co. Ltd. production began to control from raw materials, continuous selection of quality raw materials, product stability and consistency is very prominent. In powder metallurgy, the metal powder is heated by the static pressure to form a blank, which is lower than the melting point of the main component, so that the connection between the particles and the method of improving the properties of the product is called sintering. Powder after forming, dense bodies obtained by sintering is a polycrystalline material, sintering process directly affects the microstructure of grain size, pore size and grain shape and distribution, is the core technology of powder metallurgy. In powder metallurgy, the metal powder is heated by the static pressure to form a blank, which is lower than the melting point of the main component, so that the connection between the particles and the method of improving the properties of the product is called sintering. Powder after forming, dense bodies obtained by sintering is a polycrystalline material, sintering process directly affects the microstructure of grain size, pore size and grain shape and distribution, is the core technology of powder metallurgy. The material can obtain a higher density and superior mechanical properties, and play a role in strengthening the surface. Accurately grasp the processing rate of tungsten and molybdenum materials, forging and forging temperature, is an important factor in gemei tungsten molybdenum material having excellent performance. Use of metal billets forging machinery pressure, the processing method of plastic deformation in order to obtain a certain mechanical properties, shape and size of forging. Forging (forging and stamping) the two part of. By forging can eliminate the casting defects such as loose metal produced in the smelting process, the microstructure is optimized, and the preservation of the integrity of the metal flow, the mechanical properties of forgings generally better than the same materials of casting. In this process, the metal material is under the pressure of the rotating roller, which has a continuous plastic deformation, and the shape and performance of the section are obtained. Gemei has advanced tungsten and molybdenum cold and hot rolling technology and equipment from tungsten and molybdenum metal billet to the production of tungsten and molybdenum foils, gemei for you to ensure the production process is more advanced and more superior performance of metal. The heat treatment can eliminate the stress in the internal structure of the metal, make the internal structure even and balanced, and give full play to the properties of the material. In this way, cracks caused by incomplete stress relief can be avoided in the subsequent machining process. Gemei has such as cars, milling, planing, milling and other mechanical processing equipment and technology, made of tungsten and molybdenum materials to meet the requirements of various use requirements and surface. Lathe machining is a part of machining. The lathe is mainly used for machining of rotary workpiece. Can also be used in the lathe drill, drill reamer taps Banya and knurling tools for the corresponding processing. Xi'an gemei metal materials Co. Ltd. products began to quality control from raw materials, and each process of quality inspection and sampling, ensure each process products quality inspection process control, finished product, material for the apparent size and internal tissues were detected in the products one by one, the stability and consistency is very prominent.
