However, the development of combining LED lamps and thermoelectric power generation technology involves materials, electronics, machinery and other fields. “At least three million yuan of pre-research and investment is needed. One company may not be able to afford it. We hope to create an innovation alliance. Relevant technology companies can jointly establish projects and strive for government support," said Wu Yulin, general manager of Foshan Kaixiou Lighting Design Co., Ltd.
LED lamps with significant energy efficiency have shown great potential in the lighting market, but their heat dissipation is one of the challenges that the LED industry has been trying to solve. Only 30% of the power to turn on the LED light is used for illuminating, and 70% is turned into heat. If the heat dissipation effect is not good, the life of the electrolytic capacitor in the circuit will be greatly reduced, which will seriously affect the life of the LED product.
Wu Yulin said that under the promotion of the Chancheng District Science and Technology Bureau, the thermoelectric ceramic material thermoelectric power generation technology and heat dissipation technology of Foshan Huaxia Building Ceramic Research and Development Center were introduced into the laboratory of Kaixiou.
According to the data of our research and development, the efficiency of converting thermal energy into electrical energy is 5% to 10%, but the most important thing is that after heat conversion, the heat dissipation problem of LED is also obtained. Very good solution, life is extended."
Storm Circuit has been producing Multilayer PCBs for over 10years. Over the years, we have seen all types of multilayer constructions from various industries, answered all types of multilayer questions, and solved all types of problems with multilayer PCBs.
Multilayer PCB is a circuit board with two or more layers. The material unlike Double-Sided PCBs with only two conductive layers all multilayer PCBs is that it must have at least three layers of conductive material, and the PCB boards are buried in the center of the material.
Benefits of Multilayer PCBs (compared to single or double-sided PCBs)
Higher assembly density
Smaller size (considerable savings on space)
Increased flexibility
Easier incorporation controlled impedance features.
EMI shielding through careful placement of power and ground layers.
Reduces the need for interconnection wiring harnesses (reduces overall weight
