Multiple functions LED night light
DCFirst Claim
1. A LED night light including:
- a first optical element and a second optical element; and
at least one LED arranged to provide a uniform brightness over a light transmitting area of the second optical element which is separate from and assembled to a base of the LED night light,wherein the first optical element is configured to prevent people from touching electric parts, andwherein light beams exiting from the first optical element are emitted to at least one of an inner surface of the second optical element and an inner wall of the night light, and are reflected or refracted multiple times between at least two the first optical element, the second optical element, the inner wall of the night light, and a home wall to eliminate an LED spot-light effect and create the uniform brightness and a pre-determined illumination function; and
wherein at least one electrical circuit that includes electric components is arranged to drive the at least one LED according to predetermined functions, timing, effects, and brightness.

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.

5. A multiple function LED night light, comprising:
-
at least one LED arranged inside the LED night light to provide a uniform brightness over a light transmittable area of an outer front-lens or second optical element while light beams are emitted to a first optical element, wherein the first optical element is one of a tube, a cone, a ring, a multiple reflective or refractive surface piece with different diameters, and a cylinder shape having reflective and refractive optical properties;
the first optical element being configured to change a narrow-emission-angle LED spotlight into wider-emission-angle light beam that spreads out from the first optical element, andwherein the wider-emission-angle light beam from the first optical element is emitted to at least one of an inner surface of the second optical element and an inner wall of the LED night light and refracted or reflected multiple times therebetween, or is reflected or refracted multiple times between or within at least two of the first optical element, the second optical element, the inner wall of the night light, and a home wall, to create the uniform brightness performance and pre-determined illumination function on one of the outer front-lens, the first optical element, or the second optical element; wherein the LED night light further includes at least one electrical circuit to connect with prongs to deliver electricity from a home power source to the at least one LED and an added function device; and wherein the added-function device is selected from the group consisting of; (a) a sensor device including at least one of a motion, photo, or radar sensor for turning the at least one LED on or off, (b) a surge, over-heat, over-charge, electric-shock, over-voltage, or over-current protector, (c) a camera and data storage device, (d) a power fail light or emergency light or flashlight device having a backup battery for power fail use and configured to emit a light beam from a location in the LED night light that is not the same as a location of the outer front-lens, (e) at least one second LED light source for a multiple color system which emits colored light for display on the outer front-lens by an IC and a select-switch to select, set, or adjust a color related function selected from at least one of color changing, color freezing, and brightness level in response to a motion-sensor and/or photo sensor, or a timer setting for a wakeup light or sleep light; and (f) at least one second LED light source for providing an indicator light function to show a charging status, power on/off, protection on/off, surge on/off, timer on/off, and/or power consumption status, and wherein the at least one electric circuit includes electric components selected from the group consisting of a resistor, capacitor, switch, sensor, diode, inductor, transformer, and integrated circuit, said components being arranged to drive the at least one LED and to drive the added-function device to provide predetermined functions. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. A multiple function LED night light including:
-
at least one LED arranged to serve as a light source for at least one of; (1) an even brightness display on a light transmitting area of an outer front lens, even brightness resulting from multiple times reflection and refraction of light beams between at least two of; (a) a first optical lens included in a (i) tube, or (ii) cone, or (iii) reflective or refractive surface piece, or (iv) ring with different diameters (b) the outer front lens or a second optical lens having reflective and refractive optic-properties, and (c) a light reflecting, non-transparent inner wall of a housing, or (2) a location or status indicator-light display directly behind one and only one of a front cover or lens; and at least one electric circuit to connect with at least one prong to deliver electricity from a home AC wall power source to the at least one LED and turn on the at least one LED for illumination according to predetermined functions, time, duration, color, and brightness, and also to deliver the electric power to at least one non-wireless additional function or device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
