Why Use LED Lighting?

• LED lighting provide an excellent source of illumination, long life, safe and energy efficient.
• The LED Low-voltages contribute to extended LED life and increased safety.
• Small fixture sizes and low heat.
• Common applications include residences, display lighting, task lighting, and product highlighting.

Why Use Constant Current driver?

LEDs are current-driven devices whose brightness is proportional to their forward current. Forward current can be controlled in two ways. The first method is to use the LED V-I curve to determine what voltage needs to be applied to the LED to generate the desired forward current. This method has several drawbacks, any small change in LED forward voltage creates a larger change in LED current, it will increase power dissipation and reduce the LED life.

The second preferred method of regulating LED current is to drive the LED with a constant-current source, this method will eliminate changes in current due to variations in forward voltage, which translates into a constant LED brightness.

CHARGERY develop and produce high efficiency Constant Current driver for LED.
