Abstract

A multiple function LED night light has at least one LED device and added function(s) such as an air-freshener adaptor device, sonic device, frequency device, sensor device, bug repeller device, second light device, timepiece, electric message device, timer device, temperature device, surge protection device, electric short circuit protection device, base device for installation on an existing lamp socket, emergency light device, or any other electric device(s) suitable for home use to keep people comfortable or safe. The LED device has a first optic means to change the narrow-viewing angle of an LED'"'"'s spot-light beams into a wider-viewing angle and second optic means to help make the LED night light exhibit a smooth lighting effect. The device may be arranged to fit into an existing night light bulb socket to turn any existing bulb night light into a power saving LED night light.
