US Patent 9141101 Wireless battery-powered remote control with glow-in-the-dark feature

A glow-in-the-dark night light for a control device allows the control device to be easily found when the control device is located in a dark space. The night light may be provided on an actuator of the control device and may comprises a glow-in-the-dark material that has a luminance spectrum that decays with time after initial excitation. The night light is illuminated by an electromagnetic-energy-generating element to periodically recharge the glow-in-the-dark material with adequate energy to keep the glow-in-the-dark material visible in low ambient light conditions. The electromagnetic-energy-generating element draws relatively little current, such that the night light may be provided in a battery-powered remote control that has an acceptable battery lifetime.
