Recently, from the China Saibao (Headquarters) laboratory, there was a big news. Qinshang LED street light passed the CQC product certification, and Qinshang Optoelectronics became the first company in the industry to pass this certification.
It is understood that China Saibao (Headquarters) Laboratory specializes in the detection, appraisal and evaluation of electronic and electrical products. It was approved by the former Ministry of Electronics Industry and is administratively and economically independent of product manufacturers and product users. A non-profit third-party testing agency. It is a national inspection agency and the first internationally accredited laboratory in China.
The reporter learned from Jiang Chunxu, deputy director and senior engineer of the electronic product room of China Saibao (headquarters) laboratory, that the 8 series of 4 LED street lights of Qinshang Optoelectronics passed the safety test and electromagnetic compatibility test of CQC product certification at one time. Its safety has reached the requirements of the latest national mandatory standards GB7000.1-2007 and GB7000.5-2005.
In terms of power supply security, Jiang Chunxu made a detailed introduction. He said that the LED street light is powered by an isolated switching power supply with a wide voltage range, which avoids the safety quality hazard caused by poor power quality and improves the power adaptability of the LED street light. IP67 waterproof and dustproof power supply, the protection level of the lamp itself also reaches IP66, which is higher than the national mandatory standard for dustproof and waterproof requirements, good sealing, heat and humidity resistance, and improved complex outdoor environment adaptability.
The power supply adopts ultra-thin design streamlined high-strength integrated casing, which can withstand wind speed of 188km/h (52m/s), achieves the ability to resist 16-level strong typhoon, and has high mechanical safety factor. The grounding resistance is lower than 0.1Ω, which is far below the requirement of 0.5Ω in the national mandatory standard. The grounding continuity is good, and the leakage current is lower than 0.5mA, which is lower than the 1.0mA limit requirement stipulated by the national mandatory standard. The insulation resistance is above 250MΩ, which is far higher than the limit of at least 4MΩ specified by the national mandatory standard. The overall safety factor of electric shock protection is high.
He believes that because the LED module works under the safety special low voltage, there is no safety hazard during installation and use, it is safer than using high voltage power supply, especially suitable for public places. The LED works in constant current mode, which makes the working state of the LED more stable, ensures the consistency of the light output of each LED, and improves the reliability life of the LED. The use of cold light source avoids infrared and ultraviolet radiation, and the light biosafety is good and greener.
Jiang Chunxu also pointed out that the eight 4 series of LED street lights have met the requirements of the mandatory national standard GB17743-2007 and GB17625.1-2003. They have strong anti-space electromagnetic interference capability, no harmful electromagnetic interference to the environment, and no high-order operation. Harmonic component leakage, power factor up to 0.95, high power efficiency, small surge at startup, no harm to the power grid.
So, how to solve these technical problems that have passed the certification for the technical problem of heat dissipation? In this regard, the reporter interviewed the person in charge of the Qinshang R&D Center. He said that the LED street light adopts integral heat sink and unique heat conduction heat transfer method, which has good thermal management effect, low temperature on the inner and outer surfaces, safe and touchable, and highest rated. The ambient temperature exceeds 45 °C, which can meet the requirements of China's tropical climate and summer hot weather.
The person in charge also said that the CQC product certification passed this time is a voluntary certification of enterprises. This aspect illustrates the self-confidence of the products on the diligence, and on the other hand, the responsibility of the industry leader for the development of the industry. As the most promising energy-saving and environmentally-friendly high-tech in the world, LED lighting is currently the most sought-after industry. In the next 3-5 years, LED industry scale of over several hundred billion yuan will be formed, and the prospects are very broad. However, at the same time, the rapid development of the industry has also brought about some new problems, mainly in two aspects: First, the long-term lack of industry standards, resulting in mixed products on the market, mixed with fish and dragons; Second, the lack of corporate service awareness and no unified norms Some manufacturers have low-priced dumping and vicious competition, which has caused the development speed and quality of the LED industry to be greatly affected.
Qinshang Optoelectronics has been advocating and participating in the establishment of industry standards. The CQC product certification is to establish a demonstration effect in the industry, so that more enterprises in the industry can go to the standard track, standardize the production and sales market, realize the survival of the fittest, and promote the new round of reshuffle. Industry competitiveness, promote the healthy development of the LED industry. Prior to this, Qinshang Optoelectronics also drafted the "Guangdong Province LED Road Lighting Local Standards", which has officially entered into force on July 1, 2009.
