How to coordinate the LED lighting products competition among enterprises?

Li Bingjie: Epistar OEM business and the Epistar basically does not exist a competitive relationship. With the rapid development of semiconductor lighting products, industry environment has begun to change at present. Many international enterprises are committed to the vertical integration. Their value achievement is to take the while industry chain into consideration, focusing on the development of its own core strengths. For some high-volume sales and standardized production of LED lamps, When LED lights chips is provided by such Epistar, professional LED chip suppliers, the provision of these enterprises will not tend to put into a great deal of money in the chip production. These international enterprises will put the chip production orders to the professional chip suppliers because the core value of their products is very difficult to reflect on the chip level. The Chip enterprise can either sell their chip to this enterprises or can also be sole to other companies. Only their own resources invested in the aspects which superior to others and do other aspects of the products well, and form their unique value, that is the way to win. If he only persists in the chip field investment, it cannot reflect the product advantages, but because their own production of the chip, while the competitors do OEM by Epistar, they will be weaker than competitors in the cost. On the other hand, If its demand is large enough, the competitors will form a certain advantage when they bought all the products that OEM did.

In short, for some companies, the value of the standardized LED chip will be increasingly low. They will think about abandoning chip production gradually to the foundries in the industrial chain to find and focus resources to their own advantage. At this time, the OEM will form.

In addition, the LED chip foundry services segment of the subdivision, because not only vertically integrated firm has purchased chip demand, but many small lighting products business will also be on chip demand. However, the demand for foundry services have different product needs of the manufacturers of large-scale, standardized, small factories and small quantities of custom. The positioning of the different foundries will change, and some specialized services to manufacturers, and some specialized services to small factories.

The flaws behind the scenes of LED lighting products

With its excellent energy saving effect, LED lighting products has still become the preferred product in peoples daily lighting, even in the era of energy crisis.

At present, nearly all traditional lighting companies are involved in the field of LED lighting. We did not suspect that the LED’s prospects and market space. Compared to the traditional lighting products, LED lighting products market share is relatively small. Although LED lighting products are talked about as emerging energy-saving products, However, we have to be realize that LED products still exists some difficult problems.

1, Weight: Compared with traditional energy-saving lamps, it is clear that its weight is larger than traditional ones. The screw interface lamps, fluorescent light weight is of only one of the LED lamps. Because of heat sink, the weight of the fluorescent lamp can be negligible, but it will be a very serious test for LED.

2, Life: LED life bottlenecks is in the system driver board. The system drive was broken even the LED wick is not damaged. LED light decay is very serious because most of the existing LED home lighting protection is not easy to do well by size limits, large voltage fluctuations.

3, Efficiency: Why should think about the issue of efficiency?  One is PF date, the other is system efficiency. As a large majority of the LED design are lower power, it commonly use of the passive PFC because of the cost pressure. The PF maybe up to 90, far less than the efficiency of active PFC. There will be much pressure for LED to replace the fluorescent lamps which is very close to the luminous efficiency.

4, Sense light: One advantage of the LED is the spectrum of pure, but it is a very serious disadvantage in the visual sense. The human eyes can not observe a single chromatographic light for a long time. ‘

5, Cooling: The LED poor heat resistance will bring much trouble for the wick life. The existing LED lights is very difficult to meet the heat dissipation requirements.

6, Price: LED driver board maybe only have 5 year life in a temperature of 70 degrees which is far from 10 years of LED wick “concept” we expected to be. Therefore, Compared to the same brightness of the fluorescent, even fluorescent lamps is only for one year life, 1W1 fluorescent lamps is much more cost-effective than the 1W10$LED.

We must solve these difficult problems if LED would like to become popular lighting tool.

What kind of LED lighting products does African market need?

What kind of products does African led lights market need? This is the primary problem faced by the lighting companies who wish to enter the African market. The African market is the low-end applications in the lighting market, but low-end does not equal low-cost. Lighting products companies in China exist deviation in the product positioning. Mainly in the blind pursuit of high brightness, power is not conducive to lower costs. China’s product itself has a cost advantage. Wang Guohua pointed out that the African led down light market is not very high requirements in terms of product performance, lower cost, with basic lighting functions, reliability and durability to ensure that the product of three years without replacement, simple operation to meet the market demand.”

What kind of LED lighting products does African market need?

At present, 1.7 billion people in worldwide living in the dark. In Africa alone, there are 500 million people who live without electricity. For an inspection who tour the lighting conditions of the African market. This is absolutely not just a bunch of numbers, their personal life feel the desire for bright people in Africa. “About 90 percent of the rural population in Africa has no electricity supply. The small streets of many cities basically have no street lights, one evening, the small vendors in the market will lose the hustle and bustle during the day.” Basic lighting and municipal lighting market is the most potential market in Africa and it is in urgent need of development.  However, the off-grid solar lighting products are the most suitable one. the indoor small portable lights, a 5-watt solar LED bulbs, emergency lights, etc can meet the basic lighting needs, and which are the promoting product in the near future. It it noteworthy that the differences of the existing street lights of the African market and China’s domestic development, many parts of Africa market and China’s domestic development. Many parts of Africa is directly tried to telephone poles, and in order to prevent damage to the shell on some street lights and also wrapped around a circle barbed wire.  Looking from the installation form, the optical configuration can not achieve the lighting effect, which requires enterprise to think about how to integrate our existing technology, and combine with local LED lighting products and installation conditions.”

 

 

Exports of lighting products should comply with the target market standards

China is a global lighting fixtures production and consumption country in which  energy-saving lamps (led lights), incandescent production rank the first in the world. Under the stimulation and encouragement of government policies, the Chinese lighting industry has been booming. At the same time, the Chinese lighting industry have been expanding, the size and number of domestic lighting enterprises also simultaneously expand, and has attracted many foreign giants to enter.

Exports of lighting products should comply with the target market standards

Simultaneously, faced withe the global wave of energy saving and environmental protection can be achieved “green” LED lighting fixtures began to rise, showing the trends of rapid growth in China’s lighting products market. This has attracted more and more foreign enterprises tentacles into the business, and actively layout of the Chinese market, especially in the LED lighting market to get the next leadership opportunity.

It is no doubt that China’s lighting products market is undergoing rapid development. Flowing into the China market, the foreign enterprises must understand the local situation from the policy level and market level, producing for Chinese consumers need.

On the other hand, China is also a lighting products exporting countries, 70% of domestic production for export, in which North American and European markets. These two regional market requirements on product quality and usually require CSA, UL, CE and RoHS certification. With rising energy prices and concern for environmental issues, corporate and household lighting energy efficiency requirements have become more sophisticated, and thus more biased in favor of select energy-efficient, low-power products.  In this regard, the foreign market-related government has such projects, such as energy efficiency requirements of the product the higher the Energy Star program.

As foreign enterprises enter the Chinese, they need to comply with the policy of the Chinese market, domestic enterprises need to know the policy and market requirements of foreign market, while expand the North American and European markets. Take North American as an example, they usually need a reliable third-party testing and certification organization such as CSA Group. To test the product structure, quality and safety features to ensure that these aspects are in line with the requirements of relevant standards. Certified products can affix the certification mark by a third party testing and certification organizations.

LED lighting products quality explanation

In order to develop LED lighting technology, developed countries focus on the LED lights features, temperature characteristics and lumen characteristics, test methods, and try to establish test methods and technical standards of the whole set of LED. LED test has been walking in the forefront of the world.

LED lighting products quality explanation

Different applications determines the performance requirements of LED lighting products. From the point of view of optical performance, the LEDs for display, and more attention to the luminous flux, spatial distribution of the beam, the parameters of color, the color rendering properties, and biological application of LED panel is more concerned about the parameters of the biological effective radiated power, the effective irradiates. About its quality, it must be a comprehensive evaluation of many aspects of optical, electrical and thermal.

From the current structure and industrial development of LED lighting products, LED lighting products mainly consider several parameters of the optical properties, electrical properties, thermal properties, radiation safety and lifespan.

Optical properties: the optical performance of LED are mainly related to the performance requirements of the spectrum, brightness, and chroma. According to new industry standards set by “the semiconductor light-emitting diode test method “, the main parameters are peak wavelength, spectral radiation bandwidth, axial luminous intensity, the beam angle of half intensity, luminous flux, radiant flux, luminous efficiency, aromaticity coordinates, color temperature, color purity and dominant wavelength and color rendering index. The display LED are mainly visual effects, so the correlated color temperature and color rendering index is not required. and the white LED lighting, these two parameters is particularly important. It is an important indicator of lighting atmosphere and the effect, while the color purity and dominant wavelength is generally not required.

Electrical properties: LED’s are PN junction electrical characteristics, and it determines the electrical properties of LED lighting products applications, that is  one-way non-linear electrical properties, low-voltage drive, as well as sensitive to static electricity and other characteristics. The main measurement parameters include the forward drive current, forward voltage drop and reverse leakage current, reverse breakdown voltage and electrostatic sensitivity.

Thermal performance: lighting with LED luminous efficiency and power is one of the key issues in the development of LED industry, at the same time, LED PN junction temperature and shell heat issues is particularly important, generally with thermal resistance, junction temperature and other parameters.
