Foe laser light source incorporate with flat top protective lens and laser film or grating film to enlarge or created plurality of image, lighted patterns. For LED light source can has project assembly which is a built-in or add-on or assembled inside of said light device. Further can incorporated flexible bendable arms to change position, direction, orientation of (LED or-and Laser) light beam. The said Light device also can offer near-by and far-away illumination, or-and lighted image, pattern projection with desired light effects by rotating optic-lens or LED(s). It also can get desired effects while LED(s) controlled by IC or circuitry making LED(s) for color changing or on-off on desired time, duration, cycles. The light device further can have more than one function selected from USB charger, power failure, RF remote control, Infra-red controller, blue-tooth, wifi, internet, App software, motion sensor and wireless with multiple-way communication. Also, light device may have rechargeable circuit, batteries or rechargeable battery, USB ports for the (LED or-and Laser)-bulb be charged or supply other device current.

A humidifier apparatus may have at least one reservoir configured for holding a liquid. At least one device is for creating vapour from the liquid. At least one ventilator may cause a movement of the vapour exiting the reservoir. One or more light sources project lights on the movement of vapour. A method for operating a humidifier apparatus and creating flame-like vapor.

An LED or laser projection light has more than one function, which may include functions of a conventional all-purpose light device and additional projection light functions using different light sources to project a light beam, image, or digital data from a digital data storage means, as well as functions of a desk top light, floor light, garden light, emergency light, safety light, anti-burglar light, underwater light, street light, reading light, night light, light fixture, motion sensor light, power fail light, photo sensing light, dimmable light, spotlight, seasonal light, Christmas light and/or ornament, licensee products, cartoon character related products, promotion light, commercial light, sign, motion sensor light, blue tooth light, moving device light, car light, vehicle light, boat light, aircraft light, and or multi-function LED light or Laser, with rechargeable or non-rechargeable energy storage kits having preferred circuit means, switch means, sensor means, timer means, IC means, electric parts, and accessories.

An underwater directional light is provided. The directional light includes a lamp assembly, a tube assembly, and a printed circuit board assembly. The lamp assembly includes a housing and a lamp having a plurality of lighting elements. The tube assembly is coupled to the lamp and has a hollow interior. The printed circuit board assembly is mechanically coupled to the tube assembly and electrically coupled to the lamp.

A method for appreciating water balls using a water balls appreciation device, including a water balls discharge device and a light irradiation device, the method including: discharging the water balls, using the water balls discharge device, from tips of a plurality of nozzles, disposed at predetermined intervals in the lateral direction, by applying vibration to flowing water, the discharged water balls falling downwardly and in substantially a vertical plane; irradiating the water balls, using a light irradiation device, with light, the light irradiation device comprising a high-speed projector having a refresh rate of 300 Hz or more; and projecting a continuous screen of the projector in the water balls in the vertical plane regarded as a virtual screen by properly using a frame displaying a screen or an image and a frame not displaying a screen, so that a blinking duty is 20% or less, whereby the water balls are visually appreciated in the projected area. Then, by changing the timing of light emission for passing light through the image, it is possible to appreciate the movement of the water balls that changes in various manners.

A hanging liquid lamp system is provided that enables a vessel containing two or more liquids to be suspended securely from a support structure while providing power to components of the liquid lamp.
