Information picture Nanfang Daily News Consumers may not understand the phenomenon of LED lamps may end. Yesterday, 7 LED lighting companies in Foshan jointly issued the LED lighting product packaging label Foshan Union standard. After 3 to 5 months, consumers will see LEDs with key parameters such as warranty period, color temperature and color rendering index in the market. Lighting.
It is reported that the standard is used for LED lighting products directly provided to consumers, including Foshan Lighting, Midea Lighting, Guoxing Optoelectronics (002449, shares), Blue Arrow Electronics, Zhaoxin Lighting, Zhonghao Optoelectronics, and Caseo Lighting. Foshan lighting companies must pack LED lamps according to this standard.
The person in charge of the marketing department of Foshan Qiandeng Store told the reporter that the parameters of different brands of LED lighting products on the market are very different and not complete, and consumers can't distinguish them. Consumers want to know what performance they can pay for the extra price, but they don't see it from the packaging, and we don't know how to explain it to consumers.
The above-mentioned alliance standard shows that in addition to the traditional parameters such as rated power and voltage, the package identification needs to clearly identify the product characteristics of the LED, such as photoelectric parameters (including nominal luminous flux or luminous efficacy, color temperature, color rendering index), power factor, Product warranty period, product quality, relevant warning signs, etc.
Xu Liancheng, deputy general manager of Guangdong Zhaoxin Lighting, said that LED as a light source is very different from traditional lighting. It is necessary for manufacturers to explain the key performance of products to consumers on the packaging.
It is worth noting that this standard is based on the US Energy Star and requires the luminaire to identify the warranty period, rather than the theoretical lifespan used by many manufacturers. Wu Yulin, president of Foshan Lighting Association, told reporters that LED lighting has a longer life span, but due to various factors such as module, drive control and lamp structure, the reliability of current LED lamps is unstable, so it is required to mark on the label. Product warranty period to improve product quality and protect consumer interests.
How to understand LED parameters?
Linking the radiant energy of the total luminous output of the rated luminous flux LED, which indicates the performance of the LED and the energy saving effect;
The color temperature indicates the scale of the light color of the light source. The color temperature of the light source is different, and the light color is also different, giving people a different feeling. The color temperature is expressed in units of K, such as 4300K, the warm color temperature is low (4300K ​​is yellow warm light), and the cold light (mostly white light) has a higher color temperature. The same is true for blue flame temperatures that are higher than red flame temperatures.
The color rendering index refers to the degree of conformity of the object under the illuminated light source with the color under sunlight, reflecting the reducing power of the color of the illuminated object. The lower the color rendering index, the higher the distortion of the object under the illuminated light source. It is an indicator of the visual quality of the human eye to the light source. In general, LED luminaires should have a color rendering index of at least 8085.
The alliance standard brings the right to speak in the industry. This is the second alliance standard issued by Foshan LED lighting companies. Yesterday, Chen Jinhan, director of the Standardization Division of the Guangdong Quality Supervision Bureau, told reporters that as of the end of last year, Guangdong had 109 standard alliances and issued 283 alliance standards. The alliance standard has become an effective way for Guangdong enterprises to obtain the right to speak in the industry.
In the South China Sea alone, the number of national standards, industry standards and local standards that enterprises and institutions have participated in has reached 242, ranking first in the county and district level. Companies such as Jianmei Aluminum, Lifeng Machine Tools, and Oriental Medical have become the drafting professional households of national standards and industry standards.
A typical case is Yanbu underwear. After implementing the Alliance Standards Strategy, the influence of Yanbu Underwear has improved significantly. Last year, the Yanbu Underwear Standard Alliance and Gree Electric Appliances Co., Ltd. and Guangqi Honda and other enterprises were designated as the top ten advanced manufacturing standardization pilots in the province. The "Basic Safety Technical Requirements for Underwear Products" in the Yanbu Underwear Alliance Standard is about to rise to the local standard of Guangdong Province.
In Zhongshan, the company has developed the quality standards for Dayong Hongmu furniture products. The implementation of the alliance standards unifies the technical threshold and banned non-standard production. Although the number of furniture companies has decreased from more than 400 to more than 170, the output value has increased from several hundred million to more than two billion yuan, occupying more than 60% of the national market share.
The relevant person in charge said that many industrial clusters in Foshan have expressed strong willingness to formulate alliance standards. For example, the development of Lingnan cultural tourism in Xiqiao requires the alliance standard of the hotel industry, and LED is more passive because of the lack of standards.
