This product is once again innovated in Wanbang's unique MCOB packaging technology, using ceramics as a substrate, greatly improving the luminous efficiency of LEDs! After many research and development tests by Wanbang, the overall lighting effect of the ceramic hollow series LED bulb has reached 170lm/w! In addition, the Wanbang ceramic hollow series bulbs have a luminous angle of 330 degrees and achieve full-body illumination, which not only provides a reasonable brightness distribution, but also meets the market demand, and ensures the high quality of commercial lighting!
Wanbang entered the LED market in 2006 and aims to become a pioneer in the LED industry. The unique packaging method of Wanbang's independent innovation "MCOB" makes the performance parameters such as light efficiency and color rendering index far higher than similar standards. In 2011, the National Semiconductor Light Emitting Device (LED) Application Product Quality Supervision and Inspection Center detected that the 3.6-watt LED bulb lamp jointly developed by the Haixi Research Institute of the Chinese Academy of Sciences, Fujian Wanbang Optoelectronics and Jingneng Optoelectronics achieved a luminous efficiency of 134.4 lumens per watt. More than the overall light efficiency indicators of LED bulbs publicly reported in domestic and foreign literature. The product uses a crystal LED high-efficiency chip, Wanbang MCOB package unique technology, and Wanbang's hollow bulb structure design, with independent intellectual property rights. The product was unanimously recognized by domestic and foreign customers shortly after its launch and has been introduced to the market on a large scale.
Wanbang Optoelectronics constantly refreshes its history and continues to bring shock to the LED industry. It continues to lead the development trend of LED technology and continuously inject new blood into the market. Wanbang Optoelectronics will always keep its promise---the road to innovation will continue!
Why do you like to use ferrite magnets? Because it does not rust, does not oxidize, does not corrode and is absolutely environmentally friendly.
Why don't ferrite magnets rust?
The chemical name of ferrite magnet is iron tetroxide. The main components are: Fe3O4. It is already an oxide of iron, so it is very difficult to be oxidized again. Other magnets (the main component is iron) are made of magnetized metal iron or other elements. Like other iron and steel, they can be oxidized and rusted, and the oxidized part will lose their magnetism.
What are the advantages (advantages) of ferrite magnets
1. Low cost, low price. Raw material cost is cheap.
2. Good temperature stability. It can be used in temperatures of -40 degrees Celsius and +350 degrees Celsius.
3. It is just mentioned that it does not rust.
4. The demagnetization curve is approximately a straight line.
5. Light weight, density is (4.6-5.1) X103kg/M3
6. The anisotropy constant of the magnetic crystal is large.
7. Large coercivity Hc (between AlNiCo alloy material and rare earth cobalt permanent magnet material)
8. High resistivity.
