Abstract

A multiple function LED night light not only offers LED illumination with predetermined colors, functions, or effects, but also includes additional functions such as providing a power source, sensor(s), power fail functions, and wireless control functions. Lighting effects may also be achieved through the use of multiple optic or protective lenses that cause multiple reflections and/or refraction of light beams emitted by one or more single or multiple color LEDs.

First claim

I claim:

1. An LED night light including:
at least one LED arranged to serve as a light source for providing illumination, the at least one LED including at least one of (1) a white color and (2) a multiple color chip or dice built-in the at least one LED rather than a plurality of separate colored LEDs; and
at least one 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 and off the at least one LED by a photo sensor or manual switch for white color light illumination,
wherein the at least one prong extends from a night light geometric housing or a prong circuit base to accommodate the at least one LED,
wherein the night light has at least one first optics piece and/or at least one second optics piece to eliminate or change a bright spot caused by the at least one LED, and wherein:
(a) the first optics piece is at least one of:
(a-1) at least one of a tube having a top end, a cone having a sharp tip, and a planar or dome piece, fitted within the prong circuit base and located on top or in front of the at least one LED;
(a-2) a partial cylindrical piece fitted with the prong circuit base or geometric housing and located on one side or in front of the at least one LED;
(a-3) at least one curved or flat reflective piece which does not transmit light, an annular piece having multiple levels or diameters, or a dome-shaped optics lens or piece; having at least one of reflective and refractive properties, and fitted within an inner night light housing and located on top or in front of the at least one LED; and
(a-4) inner or outer non-light-transmitting reflective surfaces or walls of the prong circuit base or night light housing;

(b) the second optics piece is included in or fitted to the prong circuit base or the housing of the night light, and is at least one of:
(b-1) a geometrically shaped unit having a treatment, whitening, at least one opening, bubbles, and/or texturing;
(b-2) one of a cartoon mask, unit, or body; having at least one light transmitting area or hole;
(b-3) a unit that lacks at least one of a rear, top, or side wall; and
(b-4) an outer surface of a front cover or a front housing, and

wherein light beams from the at least one LED:
(i) pass through the first optics piece and are shown on at least one area of the second optics piece;
(ii) are emitted to at least one of (ii-1) the inner non-light-transmitting reflective surfaces or walls, (ii-2) inner walls of the night light or prong unit, and (ii-3) under the second optics piece, an inner isolated compartment without any electrical parts; for reflection and refraction multiple times to exhibit light without bright spots on the second optics piece; and/or
(iii) illuminate a home wall.

2. An LED night light as claimed in claim 1 , further having an additional function provided by at least one receiving port including at least one of an adaptor port, a USB port, an outlet, an audio receiving port, or a memory kit receiving slot; to deliver current or electric signals or digital data.

3. An LED night light as claimed in claim 1 , further having an additional function provided by at least one of an air freshener, a fragrance refillable piece, a liquid or wax fragrance, or a deodorizer device.

4. An LED night light as claimed in claim 1 , further having an additional function provided by at least one of a sonic repellant, mouse repellant, mosquito high-voltage shocker or terminator, and bug repellant device.

5. An LED night light as claimed in claim 1 , further having an additional function provided by at least one of a USB charging or recharging circuit or device to deliver power or direct current.

6. An LED night light as claimed in claim 1 , further having an additional function provided by at least one of a (i) wireless transmitting and/or receiving device, (ii) IR or RF remote control, (iii) wi-fi system, (iv) wi-fi extender, (v) router, (vi) APP download software, (vii) internet device, and (viii) 3/4/5G or more advanced network device.

7. An LED night light as claimed in claim 1 , further having an additional function provided by at least one second or more LED light source, each having one of:
(i) a different position or location or orientation relative to said at least one LED, or
(ii) a light-emitting direction that is different than a light-emitting direction of said at least one LED.

8. An LED night light as claimed in claim 1 , further having an additional function provided by at least one second or more LED light source for a power fail light, an emergency light, or a flashlight, when the LED light has lost AC power.

9. An LED night light as claimed in claim 1 , further having an additional function provided by a second or more LED light source including at least one single white color or multiple color chip or dice built inside one LED and incorporated with at least one of an integrated circuit, or select-switch to operate one or more of the following light functions: (i) color changing, (ii) color selection, (iii) chasing, (iv) sequential, (v) fade-in and fade-out, or (vi) other light show functions or effects.

10. An LED night light as claimed in claim 1 , further having an additional function provided by at least one second or more LED light source for providing at least one second LED function or performance other than static or steady-on illumination before turning off the light by at least one of a switch, photo sensor, and motion sensor.

11. An LED night light as claimed in claim 1 , further having an additional function provided by at least one second or more LED light source to emit to a contour or edge of the night light to form a surrounding light shown within an inner space of the night light or an outside wall of the night light.

12. An LED night light as claimed in claim 1 , further having an additional function provided by at least one second or more LED light source to emit light beams to night light inside space or parts which are at least one of a (ii) wall, (ii) inner isolating or divider wall or parts, (ii) first or second optic lens or protective lens, and (ii) a housing; to reflect and refract multiple times to get substantially even brightness.

13. An LED night light as claimed in claim 1 , further having an additional function provided by at least one USB port for (1) input of power to an internal battery or circuit, or (2) output of power for charging another device incorporated with a USB wire.

14. An LED night light as claimed in claim 1 , further having an additional function provided by at least one electric message device including one audio, video, sound, or digital data device; configured to record into memory, or connect via Bluetooth, Wi-Fi, or a wireless system, to play music or sound.

15. An LED night light as claimed in claim 1 , further having an additional function provided by at least one of (i) a timer, (ii) a temperature device, (iii) a timepiece, or (iv) a weather related device.

16. An LED night light as claimed in claim 1 , further having an additional function provided by at least one power-bank having input and output USB ports, and a built-in rechargeable battery.

17. An LED night light as claimed in claim 1 , further having an additional function provided by at least one safety device including at least one of (a) a surge protection device, (b) an electric short circuit protection device, (c) an over-charge protection device, and (d) an over-heat protection device, with or without a restart or reset switch; wherein the surge protection device has circuitry to
