Multiple functions LED night light
DCFirst Claim
1. A multiple function LED night light, comprising:
- at least one LED;
at least one first optical element;
a built-in fixed and non-pivotal outer front lens or second optical element,wherein the at least one first optical element includes at least one of;
(i) an elongate member or tube;
(ii) a cone;
(iii) an annular piece having multiple levels, diameters, rings, reflective pieces or refractive pieces;
or(iv) an at least partially cylindrical shape,wherein the first optical element causes a spotlight beam from the at least one LED to spread out into a plurality of light beams incident on (a) an inner surface of the front lens or second optical element, or (b) an inner wall of the night light to provide uniform brightness illumination through the front lens or second optical element;
wherein the night light further includes at least one electrical circuit connected to at least one prong to deliver electricity from a home wall power source to the at least one LED and to at least one added function device, andwherein the at least one added function device includes a color LED or a second light device to provide light functions that are in addition to the uniform brightness illumination provided by the light beams incident on the front lens or second optical element.

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.
