Under the support of the National 863 Program, Nanjing Henderson Technology Co., Ltd. undertakes the topic of low color temperature high color rendering semiconductor interior lighting application technology and product industrialization, and in the classroom, hospitals and other indoor general lighting high power white LED industrialization Significant progress has been made in technical research.
Based on the use of domestic chips and phosphor materials, the subject has improved the heat dissipation and light uniformity of non-directional LED light sources in a limited volume through the integration of LED devices, driving circuits, secondary optics, and efficient heat dissipation systems. The optical design model of LED indoor lighting fixtures was established through optical simulation software, and the best effective luminous efficacy of the lamps was obtained. By solving the problems of electromagnetic compatibility and low power factor of the small-sized power supply, a highly reliable and high-efficiency LED was developed. Drive power supply and intelligent dimming power supply, integrated lamps using this power supply have passed the EU CE safety certification; in the COB packaged LED lighting light source technology, the direct packaging of high-power LED chips on metal-based circuit boards is realized. , Integrated power LED chip, connecting circuit and heat sink in one, to solve the traditional package of high power LED structure is complex, high cost, difficult to automate the manufacturing process.
