Judgment standard for LED lighting products

LED lights industry need pay attention to develop the measurement standards

LED light-emitting surface is small, narrow beam, he characteristics of high brightness decided the particularity of detection.In order to deal with this problem, CIE set up seperately the “TC2-45 LED measurement and TC2-46CIE/ISO LED strength measure standards ” two technical committees. CIETC2-34 team held a meeting in Vienna, headquarters in October 1997, develop and recommend CIE127-1997 LED measurement standards, it involves  LED radiometric, photometric and colorimetric measurement. But because the rapid development of LED technology in recent years, especially the white LED lighting products, a lot of problems are not taken into account in the past. Therefore, the CIE at the annual meeting held in Kyoto, Japan, in 1999, proposed by the participants on behalf of the developed countries, to develop the white LED lighting equipment standards by CIETC2-34.The Japanese delegation also submitted two draft standards of general lighting with white LED.

Judgment standard for LED lighting products

In order to develop LED lighting products, developed countries have attached great importance to the study of LED spot test methods and standards. Such as theU.S. National Institute of standard tests (NIST),organizations the
international renowned testing experts to carry out the LED test, focus on studying the LED light emitting characteristics, temperature characteristics and lumen characteristics etc.test methods,and trying to establish a LED test methods of comprehensive set and technical standards. It has been walking in the forefront of the world in the aspect of LED test. Japan set up a “white LED Test Research Council, specializing in study of lighting white LED test methods and technical standards. In order to seize the developed countries in the world of high ground of the LED flood lights research, have invested a lot of manpower and resources in the LED standards and testing , the s focus on selection the parameters and testing methods of the led characteristics in the standard.

In China, there is no corresponding national standards about the semiconductor light-emitting diode test method , so often generated much controversy between different manufacturers and users . In recent years, the professional branch of the Optical Society of optoelectronic devices in succession organized academic discussions and exchanges of a number of semiconductor light-emitting diode test method,person in the industry form gradually more unified understanding, and develop a unified industry standard SJ/T2355-2005 semiconductor light-emitting diode test method, the exchange of products in the industry, played an important role in the comparison.

LED lighting product in Central Africa Cooperation Working Conference Held in Beijing

In response to the national “China-After science and LED Lights technology partnership” appeal, in 2010 October the State Ministry of science and technology implementation of China and the Republic of Kenya higher education and the Ministry of science and technology on the construction of apropos signed ” “semiconductor lighting demonstration project” and the “memorandum of understanding on the establishment of high efficient in Vito network to illumination center memorandum of understanding”, effectively promote a semiconductor lighting cooperation, China-Africa Cooperation semiconductor lighting in February 24, 2011 working conference held in the Institute of semiconductors. The meeting about led lighting product was convened by the National Semiconductor Lighting Project R&D and Industry Alliance. The people who from the semiconductor lighting related companies attend the LED PROJECTS meeting.

At first, the government China Solid State Lighting R&D and Industry Alliance, non-semiconductor lighting cooperation projects on the development of cooperation in a report. Described in detail the background of the non-semiconductor lighting on the basis of the implementation of relevant national call, can improve the lighting situation in African countries and improve people’s quality of life, but also conducive to China’s semiconductor lighting companies to develop the African market.

The existing African LED TUBES market development experience in the business representatives and participants to share experiences and views on the lighting market in Africa. Fieldwork in the African market, a vivid introduction to Africa semiconductor led lighting product market conditions, market demand and product characteristics and market competition situation. Lighting market in Africa can be in divided into high low points, but overall, the African market for the product performance requirements are not high, simple, easy to maintain the universal demand of the product. On the project in Africa has a heated discussion about the difficulty encountered. It was agreed that Africa semiconductor lighting has a huge market demand, but the image and reputation of Chinese enterprises in African’s mind is not high and should take effective measures to quickly change and improve the image of Chinese enterprises in Africa. Delegates deeply appreciated the power of an enterprise alone. In the vast African market alone can not play the advantages of the enterprise and also can not meet market demand.

Technology trends of led lighting product chips

Austria microelectronic sensor driving lighting department director Sajol Ghoshal points out, to promote the continuous development of led lighting product technology is the main factor of LED Lights regulations. At present, the construction of the new power plant has become very expensive, so in the future ten years, governments around the world are looking to significantly reduce energy consumption. In a building, a high percentage of energy consumption come from lighting. Therefore, the new forced regulations will affect lighting system design and installation of applications. The European Union is planning to phase out the inefficient light bulbs and has formulated regulations for commercial lighting.

From the historical perspective, led lighting product is a rough control of the electrical load, with a simple switch manual control can be further refined control. For example, the lighting is a rough control of the electrical load, with a simple switch manual control that can be further refined. For example, the California Assembly Bill 32 regulations require the building to 2018 to reduce energy consumption by half. Other building codes, such as California, the Title 24 proposed more specific requirement. Such as requiring the implementation for daylight through windows and skylights capture to reduce energy consumption, and requiring the building equipped with an automatic lighting control system. Currently, low-cost passive infrared detectors has been rarely used in the room. Through building system to control lighting can greatly reduce energy consumption, and provide users with a highly optimized lighting. In this regard, it is clear that there is still a long way to go LED Panel.

Therefore, to use the advantage of  LED power and  flexible lighting control will be the main trend in the next generation of lighting systems. The program allows the lighting system to adjust the brightness and color of the led lighting product of environmental changes in order to meet the environmental requirements, such as when there is sufficient daylight in the room or no one in it, the method can automatically reduce energy consumption.

Meanwhile, with the development of LED Tunnel residential and commercial lighting applications, the demand for dimming increases, but the incandescent lamps which used in SCR dimming is still here, so the dimming driver IC architecture design need to face a wider range of dimming compatibility issues.

led lighting product should be prepared well for going out

Japan is a country of relatively strict control standards of the imported products. Formerly, when Japanese businessmen imported a led lighting product and LED projects, they have to repeatedly examine a few months, especially in the details of excellence. And now, the market demand is on the top list. Some customer’s requirement is to supply as soon as possible. Except the civil LED bulb lamp, tube lamp are demanded for a lot in shopping malls, supermarkets and other units. “A deep LED lighting business person who is in charge of Japan’s export business said to reporter on the phone. According to his estimates, orders from Japan in 2-11 was only 5 to 5 times than all the orders in the previous year. At the same time, he believes that compared to Japan, China enterprises to some extent have the advantage of labor cost, but the strict quality management system is essential. “If you products export to Japan, the sense of quality should be strong. If the quality is not good, the products can not be approved. Because the quality requirements of Japanese want to make 100 points. We can say that it is the most strictly led lighting products in the world. They are usually requiring 100% appearance, safety, functional inspection to ensure quality. Once one of the Japan’s guest asked us whether we have High Bay or Street Light. We told them that we are doing high bay and street light. They said he purchased some Chinese high bay, but the failure rate is 1/3, so he mentioned the quality of domestic high bay needs to be improved. In addition to strengthen the quality of management, and how to better understand the characteristics of market demand is also critical to develop the Japanese market. A marketing director introduced, we will meet the needs of market regardless of different region, people’s preferences. For example, in Japan, we push low wattage, as it is quite LED Street light. But United States is different. They prefer wattage like 12W, and it must be warm. In addition, we developed a lot of intelligent application of technology, such as intelligent lighting. Using I pad, I phone to control all the lights. When you come at home, all the lights will be open.

Who is in charge for Mainland China led lighting product standard

● the local industry standards stifle the vitality of the current LED Street Light market:

First, Reginal local standards. The standard will bring local color more or less, which can not meet national and worldwide development of the industry needs. It shackles of foreign enterprises to enter the local market competitiveness, and easily lead to local protectionism.

Second, The scientific nature of the local standards. Subject to the constraints of technology and local level of industrial development, the gold content of the proposed standard, and developers can not match the rapid development likely to cause the shackles of technology development.

Third, the led lighting product standard developed by the enterprise is unreliable.  Present in many areas of the LED High Bay industry standard is by enterprises organizations of their own making. Some companies, itself, with production standards are different to reach. Such enterprises to develop the industry standard for a bit?

The opened LED industry standard, although it is conducive to the development of the industry side, yet if it also can not reach to the national level, authoritative and scientific standard is difficult to guarantee. Because led lighting product standard itself have mandatory color, there is no objective and fair platform, easy to damage the development of the industry.

● The true sense of introduction of industry standards is imminent:

There have been frequent accident caused by the LED products. A hotel in Hong Kong recently occur the fire accidents caused by the outdoor LED display. Today it may be the LED display to cause the accident. Tomorrow may be the LED lighting to cause the accident. If there is no industry standard, who are responsible for the safety of the lives and property of consumers.

No related industries label is not benecial to healthy development of enterprises. Study is a required couse of the LED manufacturing. But if there is none of the relevant industry standards, what should be the guidance to corporate R&D. Enterprises will explore whether the results of the final outputs is adapt to the market or not, which is unknown.

Industry label can calm down price wars at some extend. With industry standards to spur business development and product quality control, the led lighting product market will not look the same product but the price different between mystery phenomenon. The strength of the small workshop enterprise is no longer possible to blind pursuit of price, profit and confuse the market.
