LED BAR FOR BOARD TO BOARD TYPE

摘要

An LED(Light Emitting Diode) bar is provided to enable a user to easily change a channel selecting scheme by simply changing positions of resistors in the LED bar. An LED bar(10) includes a connector(11), a resistor(12), and an LED(13). An external control signal is received in the connector. The resistor couples the connector with the LED and includes plural channels. The channel is adjusted according to a position of the resistor. The LED is connected to the resistor and turned on according to a control signal, which is received through the connector and the resistor. The connector includes a DC input pin and a control signal pin. A DC voltage is received through the DC input pin. An external control signal is delivered to the LED through the resistor and the control signal pin.
