CONTROL DEVICE HAVING A NIGHT LIGHT

摘要

A battery-powered remote control for radiating wireless signals to control a controlled device has a night light that glows with an intensity such that it is visible in a darkened room and the battery has a life span of at least about three years. The remote control also includes a wireless transmitter, a controller operatively coupled to the transmitter, a battery for powering the transmitter and the controller, and at least one control element coupled to the controller. The control element generates a signal when activated to cause the controller to operate the wireless transmitter to transmit a wireless signal to control the controlled device. The night light comprises a light emitting diode (LED) drawing current from the battery and a light pipe having a textured front surface. The remote control further comprises a power supply circuit for the LED for providing an LED current from the battery to the LED. The LED has a normal operating current range and the LED current supplied to the LED is several orders of magnitude below the normal operating current range.
