Analysis of Difficulties and Problems in the Application of LED Light Sources in Home Lighting

March 23, 2023

In the open tender, nearly 300 bidders from 110 companies across the country participated in the bidding activities. LED products including LED downlights for indoor lighting, reflective self-ballasted LED lights, and LED street lights and LED tunnel lights for outdoor lighting are listed as tender products. The National Development and Reform Commission has clearly stated that in 2012, the Chinese government will spend 40 billion yuan on LED streetlight procurement and provide 30% financial subsidies for LED streetlight users.

Generally speaking, China's LED industry pattern has a high degree of industrialization in the south. The Pearl River Delta and the Yangtze River Delta are the most concentrated areas of the domestic LED lighting industry. The upstream, middle and lower reaches of the industrial chain are relatively complete, and more than 80% of the relevant enterprises in the country are concentrated. The north relies on many universities and research institutions, and the product research and development strength is relatively strong.

Technology and price are still difficult questions

Although there are a small number of home lighting companies in Zhongshan City on the market, LEDs are used as light sources, but they have always encountered great barriers and are still in an imperfect period.

Encountered technical and equipment bottlenecks. In the technology of LED substrate materials and epitaxial wafer production equipment, the domestic LED lighting industry has obvious bottlenecks. The independent innovation and patents in the LED field of China's enterprises are mainly concentrated in the packaging stage. In the most critical white light, high-power LED lamp thermal balance problem, long-lasting and efficient phosphor, etc., the technology patent has been used by European, American and Japanese companies. monopoly. The brightness, heat dissipation, luminous efficiency and uniformity, antistatic ability, anti-leakage capability and quality control level of domestic LED lighting products are still far from the international products.

LEDs lack product pricing rights. Domestic LED companies are small in scale and industrial resources are scattered. Core chips, especially high-power LED chips, mainly rely on imports from abroad. A single small and medium-sized manufacturer can only import high-priced chips from abroad, resulting in a low bargaining power, which keeps costs high. For a single family, the energy-saving performance of LED lamps is not obvious, and it does not save much money. Moreover, LED lamps are three times more expensive than ordinary lamps, and it is also a problem for ordinary people to bear.

Lack of brand awareness LED companies have a large number of companies, mixed products, products are not in the same order, there is no independent brand, resulting in some patents being stolen, infringements have occurred frequently.

LED home road has a long way to go

According to a report issued by the relevant departments of Guangdong Province, LED companies in the United States, Japan and Europe have more than 80% of the core technology patents of LED chips, while domestic similar enterprises have less than 10% of similar patents. For a long time, the core basic technology of LED upstream epitaxial wafer and chip market has been monopolized by several foreign industry giants such as Nichia, Toyota Synthetic, CREE , Osram, etc., occupying 70% of the output value of the entire industrial chain, which also makes China's LED industry chain. The structure is very unreasonable.

Numerous bottlenecks have made the development of the LED industry still restricted, and cannot be as popular as energy-saving lamps. However, it is gratifying that in recent years, more and more LED companies have focused on the market, looking for channels suitable for their own products, focusing on the differentiated advantages of market competition; gradually strengthening the promotion and training of their own brands; paying attention to the overall environment of the region and starting Standardize the market competition order, but LED's home lighting road has a long way to go.
