US 2019/0319470 A1 · Area Illumination for LED Night Light

Abstract

The area illumination for a LED night light to apply multiple reflection and refraction theory to eliminate narrow angle spot-light(s) and create even brightness shown on optic-lens surface with simple one or two optic-lens for LED light which is one of sealed or non-sealed unit wherein the LED light beams to travel within or between at least two of the (1) 1st or 2nd optics-lens, (2) inner surface of the housing or lens, (3) housing wall to make multiple reflection and refraction to create even brightness and emit light from front of non-movable treated or whiten or opaque light-emitting out optics-lens. The LED light optionally add (A) the flat piece with frosted sheet or piece on the visible lens desired position or surface of the sealed-unit, and/or (B) multiple color(s) LEDs in chip or dice or COB (Chip on board) LEDs to make color changing, color selection, fade-in and fade-out or preferred light effects, and/or (C) switch to make one of function-selection for hi-low brightness, motion or dusk-to-dawn functions, steady or dynamite or moving light effects, and/or (D) more parts for additional functions select from (d-1) has 2nd or more LED(s) for power-failure light, (d-2) has more LEDs as indicator light to show charging status or surge protection, (d-3) has built-on USB charging functions, (d-4) has USB power bank while has rechargeable battery, (d-5) built-in at least one of camera, audio device to get image, talking, audio digital data and optional has wireless or wi-fi with download APP software to make wireless controller. (d-6) has built-in at lest one of wireless controller or trigger system select from IR, RF, motion sensor, photos sensor, radar sensor to operate the LED light for desired functions(s), light-effect(s), color changing/selection, brightness by market available electric parts and accessories.

Dependent claims

A LED night light, comprising:

at least one LED:
at least one 1st optic-element is a flat or cone or tube or dome or preferred shape;
arranged to receive incident light from the at least one of LED(s) fit inside lower sealed-base where has preferred one of circuitry, trigger system, prongs, electric parts and accessories for plug into outlet;
and
LED light beam go through 1st optics-lens to make at least one function or purpose select from (1) light passing though, (2) spread light-beam to variety angles (3) prevent people to touch the LED light-source(s) directly;
and
The LED light has 2nd optic-lens which is light-passable piece with preferred texture, treated, whiten treatments and assembled or fitted or push-tighten with lower sealed-base to make multiple times reflection and refraction of the said LED light-beam emit out from 1st optic-lens between the at least two of inner surface of (a) 1st optic-lens, (b) 2nd optic-lens, (c) housing wall, (d) LED light inner walls to create even brightness to emit out from 2nd optic-lens.
Wherein, the 2nd optic-lens has open rear-housing or without rear-housing so light-beam emit to the housing-wall or outlet-location wall without item existing for light-beam emitting direction or path to housing-wall.
