What is the reason why the LED driver power is currently inadequate

Processing LED lighting and company's technicians are not enough for the switching power supply, and the power supply made is working properly, but some key assessments and electromagnetic compatibility are not enough, still have a hidden danger; most of the LED power supply Processing companies are transformed from a general switching power supply to do LED power. The characteristics and use of LED are not enough; the current standards of LEDs are almost none, most of them are standards for reference switching power supplies and electronic rectifiers; now most of the LEDs The power supply has no uniform, so most of them are small. The purchase quantity is small, the price is high, and the components supplier are not equally fit; the stability of the LED power supply: the problem of wide voltage input, high temperature soft and low temperature work, over temperature, overvoltage protection, etc.

No one; first is The overall cycle of the drive circuit, especially key devices, such as: Capacitor in high temperature cycle, affecting the cycle of power supply; it is the LED driver to challenge higher conversion efficiency, especially when driving high-power LEDs, because all As the power of the light output, it is too low for heat dissipation. The power source conversion efficiency affects the performance of the LED energy saving effect; the current proportion of constant current driving power costs in the use of small power (1-5W) Close to 1/3, it has been close to the cost of the light source, and the market promotion is affected to a certain extent.
