Application Field

The AA3022SRC-4.5SF series LED indicators are ideal for automotive dashboard lighting applications and other industrial signal market applications. With its highly reliable performance, long life, and wide temperature range it can be used in any directional application.

Working Principle

AA3022SRC-4.5SF LEDs employs a variable voltage current-controlled driver circuit which is connected to the output of a transistor amplifier. When the signal voltage is received by the amplifier, the transistor amplifies the voltage, which is then sent to the driver circuit. The driver varies the voltage across the LED indicator to adjust the brightness of the LED. This ensures that the maximum light output is obtained from the LED, maximized its efficiency.

The AA3022SRC-4.5SF LED indicator is constructed from a single-piece molding housing that encloses the LED die. The housing includes a lens for the LED die, an epoxy around the LED, a rear-contact sheet with a power-pole connector and a printed circuit board (PCB). The rear-contact sheet connects the LED die to the power-pole connector which then connects to the printed circuit board.
