With the improvement of LED lumen efficiency and the decline of photovoltaic cell prices, solar LED lighting has gradually entered people's field of vision. In some cases, its advantages of energy saving and no need for a grid make it the best solution. Recently, Gaogong LED reporters visited the well-known solar LED lighting products manufacturer 泓昱 Lighting (泓亚光电å). The general manager of the company, Chang Baoyan, discussed with reporters their achievements in this regard and their views on the industry.

The two brands “泓昱†and “泓亚†are simultaneously
   The predecessor of 泓昱 Lighting is a division of 泓亚光电å, which mainly develops LED lighting applications. After a period of operation, Shenzhen 泓昱 Lighting Technology Co., Ltd. was established according to the plan to promote and build 泓昱 brand lamps.
   “Yuya focuses on packaging and squatting applications. Now both brands are external. Our external application products are mainly based on 泓昱. Some of the ads we play are branded. We think that the package and application should be separated. But now the rules are messy, and it doesn't matter if the package and the application are done together." Chang always tells reporters funnyly.
Rooted in the field of solar LED lighting for many years
   泓昱 Lighting has been rooted in solar LED lighting for many years. The related product lines mainly include J-type 20W solar street light, J-type 40W solar street light, J-type 60W solar street light, 60W wind-solar complementary street light, and 90W wind-solar complementary street light. "We started the research and development of this system in the past few years. At present, we have sold products at home and abroad. We provide wind-solar complementary LED street lamps to partners in some regions, and have ordered samples in many foreign countries." Chang told LED engineers. However, the company did not ship in bulk, "mainly because of the high cost of the system, the regional meteorological conditions and complex configuration, etc. There are many in the market because the lower price configuration is not in place to give users a bad impression. , affecting the overall reputation of solar LED lighting products, but they insist on providing stable and reliable products to the market.

   In order to ensure the quality, the company has a dedicated technical staff engaged in the development and application of photovoltaic street lamps. "Our competitiveness lies in LED lamps, control systems, etc., which are all developed by ourselves. This is the core of the system. Only by knowing the quality of our products can we ensure that the entire system is configured to operate reasonably and can quickly give questions to customers. Answer." Chang said.
   Optimistic about the solar LED lighting market
   Although solar LED lighting has gradually gained popularity, there are still some different sounds, such as the life and stability of fans, batteries, and circuit systems, especially in some harsh environments. In some remote places, batteries, fans, etc. may also lead to thieves.
   Chang Zong believes that many areas in China have good lighting and wind resources, such as the northwestern region, Yunnan Dali, etc., where the wind is relatively large, it is suitable for the application of wind-solar complementary LED lighting, wind-solar complementary LED street lighting system does not require grid lines and distribution The investment is unrestricted and the maintenance cost is low, which is very advantageous in the long run.

   It is understood that the company's batteries are mainly used in the products of a company in Yunnan and Shenzhen. For the domestic well-known photovoltaic battery manufacturer Suntech's products, he said that the price is relatively expensive, and it is useless now. He believes that the current effective lighting time can be up to four hours, and the solar energy problem is not big.
   Have already explored some application experience
   Mr. Chang always told reporters that after several years of exploration experiments, they have accumulated some experience in this aspect. "It is not easy to do this system well. For example, the wind turbines are also divided into the middle and lower reaches, some are generated by fishing boats, and some are street lamps. Power generation; there is a big difference between doing high power and low power." At present, the wind turbine used by the company can generate electricity at a low wind speed, and power generation starts at two meters per second. Generally, it is only four meters per second to start generating electricity according to national regulations.
   "There is also the problem of intelligent control. The street lamp adopts the complementary power supply mode. You must not let it run at full load. The street lamp control mode has light control and time control. We use the light control at most, so that the street light switch is based on The degree of light is automatically operated. The one-watt street lamp we are doing now is light-controlled. Whether it is light control or time control, or both, the intelligent management of the power-saving mode is the development direction." Your own opinion.
   Pay attention to technology research and development to ensure product quality
It is understood that so far, Yu (Yuya) has obtained two national invention patents and six utility model national patents. Among them, the multi-core flat-type high-power LED light source is an important one and their important feature. They have developed a variety of different types of high-power lighting fixtures using this invention patent, and have attracted wide attention. Now they are applying for a new invention patent combining semiconductor refrigeration and LED light sources.
   At present, the light source of the LED lighting products are all packaged by themselves, and the power supply and controller are also designed by themselves. Mr. Chang said: "For wind and solar complementary products, photovoltaic panels, fans, etc. are supplied by our partners according to our requirements. We choose suppliers to screen according to certain standards to ensure that the overall quality meets the requirements."
   泓Asian Optoelectronics is mainly engaged in packaging products, and the yield control of the products is very important. "Now our production yield can reach 98%, and the future target is 99%." Chang said. The company operates in strict accordance with ISO9001 international standards and implements all-round quality management.
