Disclosed herewith is a night lamp having a flexible upper cover, a base ring, a bottom cover, and a light-emitting assembly. The base ring is configured to be in engagement with the upper cover and the bottom cover at the same time, forming a complete sphere.

An illuminated walking assistance apparatus is disclosed. In at least one embodiment, the apparatus provides an elongated staff having a ground-engaging tip portion at a first end and a handle at an opposing second end. The staff provides a light pipe positioned proximal the tip portion and having a light-emitting member disposed therein to selectively illuminate the ground proximal the tip portion. The staff further provides a red nightlight which is always on so as to facilitate locating the apparatus in a dark environment.

A lighting unit, configured and adapted for illuminating subjects for photography and filming, has a connecting element that comprises, on the one hand, plug-in locations configured and adapted to receive at least two light sources, and, on the other hand, contacts configured and adapted to be connected to a generator, the contacts being electrically connected to the plug-in locations. At least two light sources are inserted into the plug-in locations. A substantially transparent protective cover is connected to the connecting element and at least partially encloses each of the light sources connected to the connecting element. One light source is designed as an HMI (Hydrargyrum Medium-Arc Iodide) light and the at least one other light source is designed as a flash tube. A lighting device including a lighting unit, and a reflector assembly with a lighting device, are also disclosed.

A lighting device equipped at all times in a vehicle, which can be used for camping and leisure and has a function of a safety warning light of the vehicle, according to the present invention, comprises: a rectangular-shaped fixing plate having a pair of first magnet members which are disposed horizontally; a “C”-shaped front insertion groove which is formed on the front surface of the fixing plate and is formed to be adjacent to the edges of the fixing plate excluding the upper or lower edge of the fixing plate; a “C”-shaped first support member which is selectively fixed to the front insertion groove and is installed rotatably toward the front surface with respect to the fixing plate by the medium of a hinge; a pair of side surface insertion grooves which are longitudinally formed on the respective sides of the fixing plate; a pair of second support members which are respectively coupled to the inside of the side surface insertion grooves by the medium of a hinge, and are unfolded in a direction opposite to the first support member; a light unit which has, on the rear surface thereof, a second magnet member coupled to the first magnet members, has a battery embedded therein, and has a lighting device on the front surface thereof; and a cover which is rotatably coupled to the light unit by the medium of a hinge so as to selectively cover the lighting device, wherein the lighting device may flicker when the lighting device is covered by the cover.

A Light device having built-in digital data means is powered by an unlimited power source for a lamp-holder, LED bulb, or light device connected to unlimited power source by prongs or a base that or conductive wires can be inserted into a socket that would otherwise receiving a bulb. The device may take the form of a web cam having auto tracking added one of plurality functions to make different products and functions and retractable prongs that plug directly into a wall outlet or insert into existing lamp base or incorporate conductive wire to make electric connection at least one of built-in camera, storage unit, wireless kits, Bluetooth kits, motion sensor, light device.

Chemically and thermally stable covalent organic framework (COF) materials are configured and operative as solid adsorbents for capturing gases and water.

An illuminator enables the selection of different color temperatures for different medical, dental or surgical procedures. A first circuit board is moveable with respect to the housing and a second circuit board is fixed within the housing. A plurality of LEDs are mounted on the first circuit board, which receives power from electrical contacts between the two boards. A user control enables a user to move the first circuit board between different positions, wherein, in each position, different LEDs or combinations of the LEDs emit light through the light-transmission window. Movement of the user control may cause the first circuit board to rotate or slide relative the second circuit board. The source of electrical power may be remote or integrated batteries. The rear portion of the housing may include a mount for attaching the illuminator to eyeglass frames, a headband, or other head-mounting apparatus.

An underwater diving light includes efficient cooling of LEDs and other internal electronics by heat transfer to ambient water. The water is in contact with a metallic face plate or puck that conducts heat via contiguous metal from an LED circuit board or LED face plate. Ambient water can enter the assembly to spaces between the face plate and an intermediary plate at the front of a housing to efficiently cool the LEDs and associated electronics. In a high-output form the light can emit 8000 lumens, and in this embodiment the battery is cooled by ambient water. The face plate or puck is interchangeable, for different lighting characteristics.

An aeronautical light aid for a vertical takeoff and landing (VTOL) flying object is provided. The aeronautical light aid includes a plurality of first lighting portions buried in a takeoff and landing port and configured to radiate light in a vertically upward direction, a plurality of second lighting portions provided on an outer side of the takeoff and lighting port and configured to radiate light in an externally upward direction, and a landing guide provided at the center of the takeoff and landing port.

A luminant safety eyewear device with improved lighting may feature a central light source with color changing lenses. The lenses may be manually or electromagnetically manipulated into position. Three lenses may be provided to change color emitted from white, to red, to green and/or blue. Alternately, multiple light sources or a color-changing light source may be utilized either with or without multiple lenses.
