AC LED Lighting Technology
AC LED Lighting Technology, which some one calls IC constant current , linear current regulator,
No matter what calls, it is the same way which let the LED working at a direct AC power .
it is a integrated circuit by using several smart chip( usually 10-12W/pcs) to provide a precise constant current starting from a varying input voltage source. They are ideal for replacing discrete-component LED driving solutions, providing benefits in terms of precision, integration and reliability.
An external resistor is used to set the output current up to suitable current for LED chip,
a dedicated pin can be used for PWM dimming. An open-drain pin output provides information on load disconnection conditions.
