The LED Remote Control is the one which has LED or Light Emitting Diode comprised in it, which works to send an infrared signal for controlling the device. You have undoubtedly observed that some remote controls operate only when you aim them directly at the receiver of the device, while others operate when you aim them in the general region of the receiver. This has to do with the transmitting power of the LED. A LED Remote Control with powerful LEDs sends out a stronger and wider signal.
