Japan's problems in driving LED applications

The use of LED light sources is considered an important measure to prevent global warming, so the incandescent lamp ban is being promoted globally. South Korea can be said to be in a leading position in terms of national policies, followed by the United States and Europe. The Japanese government has requested that the production and sales of incandescent light bulbs be stopped in China by 2012. In March 2010, Toshiba stopped the production of incandescent lamps. After the earthquake, Japan used LEDs to replace other light sources in indoor lighting. The government and the autonomous community are also promoting LED lighting in outdoor public areas such as roads, tunnels, bridges, parking lots, and subways.
Since the basic characteristics and technology of LED lighting products are different from existing lighting products, the existing general lighting product safety standards are not applicable to LED lighting products, and global LED lighting safety standards/standardization work has been carried out. The US LED industry standardization activities include the release of LED lighting product safety standards (UL standards). Classification of LED products according to UL standards, including: LED lighting products, LED lights, LED drivers. China and Taiwan are also establishing a standardization system. Japan, as a leading country in the LED industry, has begun to make active efforts for the standardization of the LED industry.
It should be said that Japan is the country with the most significant achievements in LED lighting in Asia. However, Japan has encountered many problems in the process of promoting LED applications. These problems have also provided some reference experience for other countries.
I. Problems in Standard Setting In Japan, relevant government departments and each association organization are discussing issues related to the standardization of LEDs. Japan has two major LED organizations, one is the Japan LED Association (JLEDS), which was founded in early 2005 by Matsushita Electric Co., Ltd. and Toshiba Lighting and LED Technology Co., Ltd., and has 145 LED related manufacturers. JapanElectricLampManufacturesAssociation, Japan Luminaries Association, The Illuminating Engineering Institute of Japan, and Japanese National Committee of CIE jointly lead the work of the association and collaborate in the field of standardization of light sources and product specifications. The association is committed to disseminating and promoting LED lighting standards, promoting LED lighting hardware trading, and publishing "LED Communication Strategy / LED Lighting" and "LED Lighting Reliability Handbook", and established the LED Lighting Standardization Committee in 2010.
The other is the Japan LED Light Source Development Association (DLEDA), which was established in 2005 and currently has 1,000 members. Its business includes promoting the transformation of industrial structure, providing funds to small and medium-sized enterprises, promoting the transformation of lighting environment, building a platform for communication between LED light source producers and consumers; supporting product development of LED light source enterprises, and supporting the establishment of LED backlight marking standards ( East Asia Guide); Develop LED backlight/marker production and construction guidelines; establish recycling systems for existing light source waste; provide human resources education for LED beginners and professionals.
In the past, Japanese law only stated three kinds of light sources: incandescent lamps, fluorescent lamps and other discharge lamps. Finally, a new term appeared on SpringLightFixture in 2010, as mentioned in the JIS amendment: such as the electric light source of LED. Japan's current LED lighting related standards, mainly JIS Japanese Industrial Standards and JEL Japan Electric Ball Industry Association standards two categories. Despite this, there are still a large number of various issues that remain unresolved. For example, the legal interpretation of electrical equipment and materials safety is not clear, so that the LED light source still has a gray area. For example, the electrical supply material of the LED lamp does not exist in the PSE certification; the LED light source is not introduced in the light source type. In addition, there are only six categories in the luminaire's shape and application classification, and LEDs are not among the six categories and cannot comply with electrical equipment and material safety laws.
In addition, large companies have developed some standards that are not compatible with the IEC system for monopolizing the market, such as the straight tube type LED lamp system (for general lighting) (JEL801:2010) with L-type lamp caps, and have not received other peers. The recognition of the people is not high.
