After the use of LED lights, power consumption savings of more than 60%, which is undoubtedly a welcome phenomenon. However, the reporter drove along several new highway repair found that different sections of the LED lamp lighting situation is different: some are very bright, some hair dark, and some lights are out. Some people who do the project to make more money, often choose cheap inferior products.

The past two years, the province's newly built highway tunnel generally used LED lighting, energy-saving effect is remarkable. Light tunnel, 24 hours full daylight, which is called the "electric tiger" because of its large power consumption, tend to charge tolls even enough to pay the bills. After the use of LED lights, power consumption savings of more than 60%, which is undoubtedly a welcome phenomenon. However, the reporter drove along several new highway repair found that different sections of the LED lamp lighting situation is different: some are very bright, some hair dark, and some lights are out. Some people who do the project to make more money, often choose cheap inferior products. Insiders say that.

In fact, the production process of LED lamp includes single crystal growth, epitaxial growth, chip manufacturing and packaging. The single crystal growth and epitaxial growth are generally regarded as the upstream of the industry, and the chip is manufactured into the middle of the river. The upper reaches of the industrial chain have the characteristics of technology and capital intensive, and the entry threshold is relatively low. In recent years, the central and local governments to increase support for the LED industry, for a variety of policies and preferential measures, the introduction of some local enterprises and set off large-scale LED production base construction boom. Due to the lower technical threshold low, naturally become the most appropriate incision into the LED industry, the inevitable result of such a large-scale investment in the downstream industry chain is caused by repeated construction and waste of resources, even overcapacity and bubble.

At present, most of the enterprises in China are in the middle and lower reaches of the industrial chain. A large number of enterprises are concentrated in the downstream industry chain, which leads to the downstream industry chain competition is becoming more and more serious, more low profit, some enterprises in order to seize the market, with lower product quality means lower prices, this is the result of confusion at this stage of the domestic LED market is one of the main reasons. Now the LED industry, on the one hand the influx of funds, manufacturers, operators such as bamboo shoots after a spring rain emerged; on the other hand, the state issued the corresponding unified technical standard lag, the market quality of individual products, lighting lamps and lanterns soon uneven in quality, there is a large area of light, and the poor maintainability, eating quality loss using LED the unit has been refused to use LED products. The high-pressure sodium lamp should be replaced due to the unity of technical standards, lamps, light sources, electrical aspects of the versatility of the product can be used in different manufacturers, but the application is very strong. On the contrary, each LED manufacturers according to their own standards for the production of products, it is difficult to exchange between each other. If the procurement of the overall strength of the weaker manufacturers of products, the future maintenance of spare parts are likely to be found, then spare parts of the product, including maintenance has become a thorny problem in the operation and maintenance department.

LED lamp manufacturers blossom everywhere, the increasingly intense competition, inferior products continue to fish in troubled waters appear on the market, solve the technical problems such as the price, it is difficult in the short term...... This series of problems led to the slow speed of LED lights. According to statistics, in the past two years in China, the market share of ordinary lighting products is 27.5%, the traditional efficient lighting products market share of, while the energy saving and consumption reduction of LED lighting products accounted for only 0.2%.
