How to distinguish high-power LED chips from messy LED lamps market?

In view of the chaotic market competition situation of LED lamps and lanterns, many businesses have adopted vicious price reduction wars. It is also very difficult for consumers to know LED chips for little time. The main reasons are: 1. No professional instruments 2. All the products purchased are finished products, and there is no separate test sample 3. Too little knowledge about LED chips. First, let's recognize the LED chip. What is LED? Simply put, it is a light emitting diode. In the early years, LED was mainly used in circuits as indicator lights. With the rapid development of science and technology, LED technology is becoming more and more mature and its application field is gradually expanding. LED has gradually entered the lighting market and is widely used in all aspects of life lighting. What are the main LED products we contact or recognize today? Led TV, LED display screen, LED flashlight, etc. are common LED products. For the lighting industry, there are mainly LED ceiling lamps, LED ceiling lamps, LED solar tubes and LED panel lamps that emerged only in the 2012 s. What advantages does LED have over traditional incandescent lamps and energy-saving lamps, which can make it an inevitable product to replace traditional lighting lamps? The main product advantages are :(1)Energy-saving power-saving low-carbon environmental protection. This is the main advantage that LED products will replace traditional lighting. Compared with traditional incandescent lamps, LED products save electricity by 90 and energy by 50. (2)Diverse styles. Whether it is traditional incandescent lamp or traditional energy-saving lamp, or even sodium lamp and other lamp products, they can only stay in the shape stage of bulbs and lamps. There are various forms of LED lamps Today. In addition to catering to the LED bulb lamps and LED sunlight tubes produced by traditional lamps, a large number of lamps with different shapes have also been derived, including lamp belts, lamp strings, lamp bars, modules, wall lamps, crystal lamps and other products. The large ones can be LED projection lamps and landscape lamps used for outdoor advertising lighting and landscape engineering lighting; Small LED string that can be as small as mung bean. (3)Other superior performance. Such as no stroboscopic, lead-free mercury, no radiation, high brightness, low heat, etc. Although LED products have so many advantages, from the perspective of practical application, there are still some problems in the current popularization of LED. The main reason is :(1) Core technologies such as chips are in the hands of developed countries such as Japan and the United States. The number of domestic independent research and development chips is small and the product quality is poor. (2) Despite China's vast territory and abundant resources, the information in township areas is blocked, coupled with the backwardness of scientific and technological cognition, and the promotion of LED products today only stays in large and medium-sized cities. Despite this, many businesses still feel the development trend of LED lamps and vigorously promote the popularization of LED lamps and lanterns. However, in such a fierce competitive environment, it is inevitable that there will be no vicious competition in the market. The vicious competition in the LED market is mainly reflected in (1) Merchants use inferior materials to produce products, but low prices do not guarantee the interests of consumers. (2) LED is a new product that has only emerged in recent years. The country does not have a perfect management system, and the quality of products can only be determined by the market. (3) The interests of the merchants exist in the post-stage of the production and manufacturing process, and the profits are extremely low, forcing the adoption of extreme strategies. Therefore, there are a large number of shoddy products in the market, among which the obvious one is to replace high-quality lamp beads with inferior lamp beads, and the obvious difference between good and bad lamp beads is chip. How to identify chips is a very difficult problem for ordinary people. The type of chips determines the quality of products, the length of service life and the quality of lighting effects. Here we use a simple method to identify the lamp bead chip. First of all, the tools we need mainly include tweezers and magnifying glasses. The second step is to prepare a high-power LED lamp bead. The third step is to peel off the encapsulated silica gel on the surface of the lamp bead with tweezers or bare hands, see sesame-sized LED chips. Then use a magnifying glass to check whether the grain of the lamp bead chip is consistent with the known lamp bead chip. Generally, there is a lamp bead chip description outside the product package.
