Due to the disorderly market competition in the LED lamp market, many businesses have taken a vicious price war. It is also very difficult for consumers to know that there is little time for LED chips.–Carrier tape package

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 of LED chips.

First, let’s learn about LED chips. What is led? In short, it is light-emitting diode. In the early years, LEDs were mainly used in circuits as indicator lights. With the rapid development of technology, LED technology is becoming more and more mature, and the application field is gradually expanding. LED has gradually entered the lighting market and is widely used in all aspects of life lighting.–Carrier tape package

What are the main LED products we contact or recognize today? LED TV, LED display screen and LED flashlight are the most common LED products. For the lighting industry, there are mainly led ceiling lamps, led ceiling lamps, LED fluorescent tubes and LED panel lamps that emerged only in 2012.—Carrier tape package

Compared with traditional incandescent lamps and energy-saving lamps, what advantages can led become an inevitable product to replace traditional lighting lamps?

The main product advantages are:

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

(2) Diversified styles. Whether traditional incandescent lamps, traditional energy-saving lamps, or even sodium lamps, they can only stay in the shape stage of bulbs and tubes. LED lamps exist in a variety of forms. In addition to meeting the LED bulb lamps and LED fluorescent tubes produced by traditional lamps, they also derive a large number of lamps with different shapes, including lamp strips, lamp strings, lamp strips, modules, wall lamps, crystal lamps and other products. The large ones can be led projection lamps and landscape lamps for outdoor advertising lighting and landscape engineering lighting; Small can be as small as mung bean LED light string.–Carrier tape package

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

Although LED products have so many advantages, there are still some problems in the current popularization of LED from the perspective of practical application. The main reasons are: (1) the core technologies such as chips are in the hands of developed countries such as Japan and the United States. The number of domestic independently developed 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 backward understanding of science and technology, the promotion of today’s LED products only stays in large and medium-sized cities.

Nevertheless, many businesses still feel the development trend of LED lamps and vigorously promote the popularization of LED lamps. 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) businesses use inferior materials to produce products at low prices, but the interests of consumers can not be guaranteed. (2) LED is a new product rising in recent years. The country does not have a perfect management system, and the product quality can only be determined by the market. (3) The interests of businessmen exist in the final stage of production and manufacturing, and the profit is very low, forcing them to adopt extreme strategies.

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

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

Here we use the simplest method to identify the lamp bead chip to identify the lamp bead.—Carrier tape package

First of all, we need the following tools:

Tweezers, magnifying glass

Part II: prepare a high-power LED lamp bead

Part III: we use tweezers or bare hands to peel off the potted silica gel on the surface of the lamp beads and see the LED chips the size of sesame seeds. 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 description of the lamp bead chip on the outside of the product package.
