  Shenzhen Huiye Jinguang Energy-saving Lighting Technology Co., Ltd. is one of the earliest companies engaged in LED lighting in China. Among the recent 29 LED street lamp testing companies in Shenzhen, the company's achievements are among the best. On September 29th, the general manager of the company, Mr. Tang Wei, and the technical director, Dr. Peng Zhoulong, shared with the reporters of Gaogong LED the views on the industry and the relevant situation of the test of Shenzhen Ten Cities.
The world's first company to do LED street lights
Huiye Jinguang is the first company in the world to produce LED street lights. Dr. Peng invented the world's first 120w LED streetlight from 2003 and won the silver medal at the Geneva International Invention Awards. Hong Kong Asia Television said that he launched a war of aggression against traditional lighting; LED light efficiency at that time It is still very low, using 0.06 watts of LEDs each, but in 2005, LED streetlights were successfully applied to Ersha Island in Guangzhou. It is the earliest demonstration street of LED street lamps in China, and it has been 4 years. Dr. Peng said that when they used LEDs as street lights, experts from many well-known companies did not believe that LEDs could be used for lighting. At that time, the company began to serialize products, and now the company has accumulated rich practical experience. It basically solves the world problem of light, electricity and heat that LED street lamps are extremely difficult to handle.
Dr. Peng has the earliest patents for LED street lighting and fluorescent lamps in China. At present, most companies use lighting, heat dissipation, casing, power drive, integrated compact LED lighting street lamp structure design and thermal model, LED directional lighting concept, In order to solve the problem of LED lighting failure, the theory and design of derating use, LED street light is designed into 105 roads, 13 roads each, 174 8 watts 0.6 meters light tube, 276 15 watt 1.2 meter light tubes, etc. It was first proposed by Dr. Peng, and later these became the common standards of the industry.
It is understood that the current standard size of the lamp, the power supply in the LED fluorescent lamp to replace the traditional fluorescent tube and other technologies are the company's earliest design. The lamp can be illuminated when it is powered on, and does not require a rectifier, a starter and an external power supply. Through a good heat dissipation design, there is no vicious cycle of light baking and electric baking, which ultimately reduces efficiency.
Shenzhen Ten City Wanhao pilot performance
In the test results of the “Ten Cities and Ten Thousand Miles†LED streetlights in Shenzhen announced in August, the company had “excellent achievementsâ€. In the pavement test section, the company's average illuminance and applied light efficiency ranked first, light decay ranked second, and longitudinal uniformity ranked sixth. In the laboratory part, the overall lighting efficiency ranked fourth, and the light decay ranked first. Tang is proud to say that Huiye Jinguang’s comprehensive ranking ranks first, and it is not easy to do all the data. In a doubt about LED street lights, Huiye Jinguang is undoubtedly encouraged. The confidence of many manufacturers. Mr. Tang said that I hope that everyone will get better and better. This industry will have the momentum to chase after you to promote the development of the whole market. Shenzhen is a demonstration city of “Ten Cities and Ten Thousand Citiesâ€. Through this test, the city government is requested to provide Some streetlight renovation projects have given LED manufacturers a stage to showcase the development of the entire industry.
It is understood that the Shenzhen Street Light Administration does not approve of the ranking of the test results. “Enterprises should not extract some of the content for ranking because the indicators are related to each other and constitute a whole. After the split, it is meaningless.†“The test sample is limited. The results do not necessarily reflect the true level of each enterprise. At the same time, the application area is large, especially the road surface is wide, and some street lamps do not perform well in the 12m×33m area, which does not mean that they cannot be used, on narrow roads or other occasions. There may be better performance."
The author believes that the ranking has certain reference, but each street lamp company has different considerations when testing. Instead of using the best parts to make the perfect streetlight, consider various factors to produce a cost-effective product that meets market needs.
Tang said that they have been using the industry's most efficient light source for LED street lights. The company currently uses 130 lm/W chips and waits for 150 lm/W products at the end of the year, and they will use them immediately.
It’s not an easy task to do all the various parameters.
According to Dr. Peng, there were not many LED lighting companies at the end of 2006 and early 2007, but in the second half of 2007, many LED lighting companies came up. “Many of them are transferred from electronics and traditional lighting companies. Experience is not enough, but many companies claim that they can do anything." "In fact, it is not difficult to light the LEDs, but it is not an easy task to do all kinds of parameters. It is necessary to solidify the basics," Dr. Peng said.
Dr. Peng believes that the LED lighting market is mixed and the quality of the products is uneven. Others who use poor quality LEDs will not only doubt the company, but also doubt the LED technology, especially high-power outdoor lighting products. More difficult.
International lighting giants are pouring into China, and Chinese private enterprises face enormous challenges.
For more than 1.6 million LED street lights, the "Ten Cities and Ten Thousand Miles" huge cake with a total value of more than 100 billion yuan, the three international giants Philips, GE, and Osram have entered China and launched a short-match battle. Chinese private enterprises are facing huge challenge. Mr. Tang said that at present, LED companies have no leader, no good or bad, and will be shuffled many times in the next two years. Many foundations are not strong, and enterprises with backward technical strength will be cleaned and exported. Huiye Jinguang passes the International Energy Conservation and Emission Reduction Fund. Cooperation, use EMC contract energy management model to strive to become stronger and bigger, and unite Chinese national enterprises to resist the challenges of international giants.
H05RN-F and H03RN-F are both types of flexible rubber cables commonly used for low voltage applications.
H05RN-F is a harmonized cable that is suitable for various indoor and outdoor applications. It is typically used for light to medium duty applications such as connecting portable electrical equipment, power tools, and appliances. The "H05" in the name refers to the harmonized code for rubber insulated cables with a rated voltage of 300/500V.
H03RN-F is also a harmonized cable, but it is designed for lighter duty applications compared to H05RN-F. It is commonly used for connecting small electrical devices and appliances, as well as for temporary installations. The "H03" in the name refers to the harmonized code for rubber insulated cables with a rated voltage of 300/300V.
Both H05RN-F and H03RN-F cables are known for their flexibility, durability, and resistance to moisture, oils, and mechanical stress. They are often used in construction sites, industrial environments, and outdoor events where a flexible and robust cable is required.
