LED Operates Directly From AC

Acriche is the world’s first semiconductor light source that operates directly from AC power without a converter. This makes it suitable for many residential and commercial lighting applications where the main source of available power is AC.

Operates on AC power without additional conversion circuitry

Operating Voltage: 100V, 110V, 220V, 230V

Long Life: over 35,000 hours

No converter loss = higher fixture efficacy

Operating frequency: 50/60 Hz

Available in warm white and pure white

Multiple package options

PIC Microcontroller - Basic Circuit

PIC 18F to RS232C using max232

Using max232 we can interface 18F454,18f4550 and 16f877 to PC serial port. Here you can see a very good example
