Abstract
An LED night-light includes a housing with a threaded, cylindrical opening having an interior surface adapted to receive a threaded end of a light bulb. First and second prongs are supported in parallel by the housing. The prongs have interior ends extending into an interior of the housing and exterior ends extending out of the housing such that the exterior ends are configured to engage an electrical outlet. A disk is received in and supported by a groove in the interior surface. A light-emitting diode (LED) is mounted on the disk. The night-light further includes a circuit board including an LED driver circuit electrically connected to the LED. The driver circuit energizes the LED when the first and second prongs are plugged into an electrical outlet connected to a power source.
