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.

An LED lighting system is provided for connection to a variable power source providing input power, the LED lighting system having at least one power analyzing and processing circuitry connecting to the variable power source, and being configured to identify one or more characteristics of the input power, where the characteristics are selected from amplitude, frequency and pulse width of the input power, compare one or more of the characteristics of the input power to preset control criteria either in hardware or software or both to yield a comparison result, and then control the current control circuitry according to the comparison result.

The AC power source LED light device has moving image has the moving projected image or-and lighted patterns by (1) circuitry control LEDs on-off time for desired time or period, or (2) magnetic field force to making moving, or (3) motor or movement to make move or changing of (A) the image-carrier which has preferred film/piece has opening/printed piece/textures lens/treated lens/prism-lens/variable thickness lens/marked lens/sild/film/window/craving treated lens/laser craving/or marked piece of different material/or printed piece with arts, or (B) at least one of plurality of project refractive-lens in disc or holder, or (C) LED(s); to move or change position, or location. All big images or lighted patterns or lighted arts created from LED(s) emit light beam through image-carrier as 1.sup.st optics-lens then through the 2.sup.nd optics-lens as (i) project-cover or (ii) refractive-lens; those at least has refractive or-and protective function to make the tiny lighted image or patterns created by image-carrier or texture-lens to passing though refraction properties project-cover or refractive-lens or protective-lens to get the bigger size or colorful or steady or moving bigger size image or-and patterns with predetermined view angle and size to shown on (a) building, house, fence, wall for outdoor, or (b) ceiling, walls, floor for indoors application. The said moving image effect created by having at least one of the said 3 basic-parts project-assembly fit into or built-into or install to all kind of different light's housing construction of LED projection light for outdoor or-and indoor application(s) said LED light image or lighted patterns has moving, shaking, spin, rotating, vibration to get the desired moving or-and changing effect(s) and other unique features.

An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal. The signal can be provided intermittently and a carrier wave also provided and modulated at the same time as the signal. When the signal is not being produced, the power on the power line may be power that is allowed to flow without manipulation from an external portion of the power line.

A microwave-sensor application for a light or electric device has a built-in microwave-sensor which can penetrate a wall, glass, building, garage door, or cement to detect over a 360 degree angle and predetermined vertical range. The microwave sensor can be used to activate a microwave-sensor application device or light device having an LED and/or laser for illumination or to provide an anti-theft alarm or warning.

A multiple function LED night light has at least one LED device with or without at least one additional function, 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, or base device for installation on an existing lamp socket, emergency light device, or any other electric device suitable for home use to keep people comfortable or safe. The LED device has a first optic element to change the narrow-viewing angle of an LED's spot-light beams into a wider-viewing angle, and a second optic element to help eliminate super bright lighted spots.

A light source is combined with an optic and a reflector. Light incident onto to the reflector is reflected with a single reflection. The reflector occupies a portion of a solid angle around the light source to the exclusion of the optic at least with respect to any optical function. The reflector directly receives a second portion of light. The optic occupies substantially all of the remaining portion of the predetermined solid angle to directly receive a first portion of light from the light source. A reflected beam from the reflector is reflected into a predetermined reflection pattern. The inner and/or outer surface of the optic is shaped to refract or direct light which is directly transmitted into the optic from the light source from a first portion of light and/or reflected into the optic from the reflector from the reflected beam into a predetermined beam.

The LED or-and Laser light string has more than one light performance functions has LED or-and Laser light bulb which has built-in LED or Laser or both to offer one or more LED or-and Laser light performance or functions select from (I) illumination, (2) projection, (3) party light, (4) lighted patterns, (5) light beams, (6) lighted image, (7) flood light, (8) color changing light (9) garden torch light, (10) garden landscape light string or other light string and all these functions has circuitry and controller built-in only light string or each of light-unit to make LED or-and laser light source(s) to turn on and turn-off or fade-in and fade-in or sequential or flashing or market available light performance which controller is one or more of the following parts including all parts & accessories selected from (i) sensor or photo sensor, motion sensor, (ii) detector or moving detectors, (iii) wireless or remote or IR or RF controller, (iv) switch, manual switch, automatically or timer switch (v) each light source or only light-string has built-in wireless receiver to match the wireless transmitter electric signals; those circuitry and controller is one of (a) built-in the light strings, or (b) built-in one master-control light-unit or each of light-unit, or (c) outside of the light string, or (d) outside the LED or-and laser light-unit housing, or (d) built-in power source, or (e) built-in the said light string or light-unit or LED or-and laser bulb circuity or controller.
