Zhou Lujun, director of marketing for Philips Lumileds in Asia, said that the photoelectric parameters of LED lamp beads mainly include light efficiency, luminous flux, color temperature, color coordinates, color rendering index, voltage and so on.
Since LED is a relatively new product, China's national standards lag, but the country provides product qualification tests. LEDs with international safety certifications (such as GS, CE, UL, etc.) and national product quality certificates are expensive because they are reliable in safety design.
According to incomplete statistics, more than 200 manufacturers of LED lamp beads (packaging equipment are better) are packaged in the Pearl River Delta. In addition, Taiwan, Europe, America and other places, LED packaging manufacturers are numerous, some LED lamp beads well-known brands, research and development The experience is relatively rich, the raw materials used, process control, and reliability are relatively guaranteed, but the price is high. However, the price of LED lamp beads of different brands varies greatly, and some prices even differ several times, but the quality is difficult to evaluate. If the quality is evaluated based on price alone, it is obviously unable to meet the reliability guarantee.
The cost of LED lamp beads using different chip packages is also different, and different brands of chips can not be separated by the naked eye. LED package manufacturers may appear to use small brand chips to pretend to be well-known brand chips. For LED lamp manufacturers, they need to be packaged. The manufacturer establishes a good cooperative relationship and examines the process of using the chip to ensure that the LED lamp bead of the chip package specified in the contract is purchased.
Zhou Xuejun said that it is more important to use the more optimized criteria to detect the parameters of the lamp bead during the test.
Sunlight shines on the p-n junction of the semiconductor to form new hole-electron pairs. Under the action of the electric field of the p-n junction, the holes flow from the n region to the p region, and the electrons flow from the p region to the n region. After the circuit is turned on, a current is formed. This is how photoelectric effect monocrystalline silicon solar panels work.
Application fields:
1. Household lamp power supply: such as garden lamps, street lamps, portable lamps, camping lamps, mountaineering lamps, fishing lamps, black light lamps, rubber tapping lamps, energy-saving lamps, etc.
