Shandong Liaocheng Gaotang wind-solar complementary solar LED combination lamps passed the provincial scientific and technological achievement appraisal

On July 2, commissioned by the Shandong Provincial Department of Science and Technology, Liaocheng Science and Technology Bureau held a scientific and technological achievement appraisal meeting for the "Wind-Solar Complementary Solar LED Combination Lamps" of Shandong Gaotang Rongbo New Energy Development Co., Ltd. Han Daoying, deputy director of the Municipal Science and Technology Bureau, and Hou Linjiang, deputy county magistrate, attended the meeting.

The meeting invited 7 experts from Shandong University, Shandong Institute of Light Industry, Shandong Normal University, Shandong Second Light Industry Design Institute and Shandong Haisheng Solar Energy Research Institute to form an appraisal committee. The experts listened to the project summary report made by the project team, reviewed the relevant materials, and after careful questioning and discussion, they unanimously agreed that the product has reached the domestic leading level.

Shandong Gaotang Rongbo New Energy Development Co., Ltd. is committed to the research and development of new energy products, continuously increasing investment in science and technology, strengthening independent innovation, and has successfully developed a series of new energy product technologies with independent intellectual property rights, such as new high-pole solar combination lighting and new wind turbines, and has obtained 3 authorized patents.

The wind-solar complementary solar LED combination lamp adopts a controller with multiple constant current outputs based on frequency as the reference point, making the power supply system more stable and reliable. It adopts a self-developed solar heat dissipation device, uses the principle of natural ventilation to cool the light source, and the LED light source board adopts a novel arched structure design with good heat dissipation effect. At the same time, it adopts a self-developed new breeze wind turbine and a movable blade high-efficiency wind turbine to reduce the cost of LED lamps. At present, the product has been successfully promoted and applied in many places and units such as Shandong Haisheng Solar Energy Research Institute, Gaotang County People's Hospital, Gaotang No. 1 Middle School, Gaotang County Sunwuli Community, etc. The product has the characteristics of reliable operation, stable performance, energy saving and high efficiency, low cost, and long life. The use of this lamp can greatly save electricity and reduce CO2 and SO2 emissions, with good economic and social ecological benefits.
