The Secret of Choosing LED Driver Power Supply

- Aug 29, 2018-

The LED driver power supply can be converted into specific voltage and current, which drives LED glowing. Input LED driver power supply usually includes alternating current, low voltage direct current, high voltage direct current, etc. However, Output LED driver power supply can change the voltage of constant current supply with the change of LED forward voltage drop.
The LED driver power supply can be converted into specific voltage and current, which drives LED glowing. The power supply transform into the special voltage current. In generally speaking, input LED driver power supply usually includes electronic supply, low voltage direct current, high voltage direct current, etc. However, Output LED driver power supply can change the voltage of constant current supply with the change of LED forward voltage drop.
Two important points to buy LED driver power supply
Firstly, to recognize the electronic capacity brand
Japanese Rubycom is very famous and we often see domestic Heng Ying in the market, but the price is higher than other brands’.
Secondly, IC control chip
IC control chips have the protection of short circuit, over voltage, over drive, over temperature and so on.
If we notice the above points, the quality will be very well.
The general principle
Firstly, according to the feature of LED current and voltage, it is very ideal to use constant current driver, which avoids the changes of LED voltage and current. Meanwhile, the constant voltage stabilized LED brightness.
Secondly, when using the LED power supply, we should reduce emitting heat and design good heat dissipation system.
Thirdly, to ensure the lifespan of LED products, we should control the working temperature of LED products.
Firstly, High Reliability
LED products are mainly made of LED chips, power supply, heat dissipation shell, control circuits. LED power supply determines the quality of LED products. LED driver power supply installs at high altitude, which is not convenient to repair and the cost of restoration is too high.
Secondly, High Efficiency
LED is the energy saving products. The efficiency of driver power supply is high. It is very important for power supply to install in lamps. The efficiency of power supply is higher, the consuming power is lower, the heat value is lower and meanwhile the temperature of lighting is lower.
Thirdly, Constant Current Driving
In order to cater to LED’s volt feature, LED power supply should use the constant current driving mode.
Fourthly, Surge Protection
The ability of LED surge protection is low, especially the ability of resisting backward voltage. It is important to enhance the protection. A lot of LED lighting is installed out of doors, and the power system sometimes meets all kinds of surge which leads to the breakdown of LED.
Fifthly, Temperature Protect Function
We should increase the negative feedback of LED temperature for output constant current, which avoids high temperature of LED.
Sixthly, LED power supply lifespan
In order to increase the lifespan of LED driver power supply, the products should be improved from many points. To improve LED efficiency, Shenzhen OTTIMA uses superior lifespan of electronic capacitor, strengthen power supply heat dissipation, optimize lights’ thermal design. LED power supply belongs to switching power supply. The stability of the quality of switching power supply depends on circuit designs, manufacturing techniques and the quality of devices.
Seventhly, Working Environment

To ensure the products’ safety,Shenzhen OTTIMA considered fully of LED lights in different working environment, temperature, humidity, installation location of LED power supply.
