Comparison between LED human body induction lamp and traditional human body induction lamp
Infrared human body induction lamp uses the thermal infrared emitted by the human body to detect and generate electrical signals by thermal induction elements. Through the induction device, the lamp can be controlled to turn on and off. It has the characteristics of light on when people come and ...Read more -
Heat dissipation design extends the service life of LED. How to choose and use heat dissipation materials?
Developers can improve the efficiency and service life of led through effective heat dissipation management. Careful selection of heat dissipation materials and application methods is very important. We need to consider an important factor in product selection – the application of heat diss...Read more -
Parallel design in LED drive design
Because of the VF value characteristics of LEDs, some VF values will change with the temperature and current, which is generally not suitable for parallel design. However, in some cases, we have to solve the problem of driving cost of multiple LEDs in parallel. These designs can be used for refer...Read more -
