(1) Energy saving, electricity saving, low carbon and environmental protection. This is the main advantage that LED products will replace traditional lighting. It saves 90% electricity compared to traditional incandescent lamps and 50% electricity compared to energy-saving lamps.

    (2) Variety of styles. Whether it‘s a traditional incandescent lamp, a traditional energy-saving lamp, or even a sodium lamp or other lighting products, they can only stay in the shape stage of bulbs and tubes. LED lamps exist in various forms today. In addition to catering to the LED bulb lamps and LED fluorescent tubes produced by traditional lamps, a large number of lamps with different shapes have been derived, including lamp strips, lamp strings, lamp strips, modules, wall lamps, crystal lamps, and other products. The large ones can be LED projection lights and landscape lights used for outdoor advertising lighting and landscape engineering lighting; Small LED light strings can be as small as mung beans.

    (3) Other superior performance. Such as no stroboscopic, lead-free mercury, no radiation, high brightness, low heat generation, etc.

    Although LED products have so many advantages, from the perspective of practical applications, there are still some problems with the current popularity of LED. The main reasons are: (1) Core technologies such as chips are in the hands of developed countries such as Japan and the United States, and the number of domestically independently developed chips is small, resulting in poor product quality. (2) Despite China‘s vast territory and abundant resources, information congestion in rural areas, coupled with backward scientific and technological awareness, today‘s promotion of LED products only stays in large and medium-sized cities.

    Despite this, many businesses are still experiencing the trend of LED lighting development and are vigorously promoting the popularization of LED lighting. However, in such a competitive environment, it is inevitable that there will not be vicious competition in the market. The vicious competition in the LED market is mainly reflected in (1) merchants using inferior materials to produce products at low prices, but making consumer interests unable to be protected. (2) LED is a new product that has emerged in recent years. The country does not have a complete management system, and product quality can only be determined by the market. (3) The interests of businesses exist in the final stages of production and manufacturing, with extremely low profits, forcing extreme strategies.

    Therefore, there are a large number of shoddy products on the market, the most obvious of which is to replace high-quality lamp beads with inferior ones, while the most obvious difference between good and bad lamp beads is the chip.

    How to identify a chip is a very difficult issue for ordinary people. The type of chip determines the quality of the product, the length of its service life, and the quality of the lighting effect.

    Here we use the simplest method for identifying lamp beads using a lamp bead chip.
