Devices, systems, and methods for generating illumination-invariant images are disclosed. A method may include activating, by a device, a camera to capture first image data; while the camera is capturing the first image data, activating of a first, light source; receiving the first image data, the first image data having pixels having first color values; identifying first light generated by the first light source while the camera is capturing the first image data; identifying, based on the first image data, second light generated by a second light source; generating, based on the first light and the second light, second image data that are illumination-invariant; and presenting the second image data.

The present invention relates to an underwater photographic lighting device which comprises: a flashlight body fully sealed by a seal, the interior of the flashlight body is provided with waterproof through holes, the flashlight body is respectively connected to a lamp head and a flashlight via conductive connecting cables, the lamp head is sealed by a seal, and connecting parts can be respectively dismounted from the flashlight body; and a power supply component sealed by a seal and connected to the flashlight body. Every part of the underwater photographic lighting device of the present invention is sealed, so the waterproof function is better; and each part is independent, and therefore can be optionally replaced and maintained. The battery module can be replaced and upgraded according to future need, and can be independently charged, so that the life cycle of the whole device is extended. When a beam head is used for photographing, a reflection cup and a condensing lens that are added on the beam head can increase light efficiency, so that a better photographing and recording effect can be achieved. In addition, since the device can be connected to a camera or a camcorder without a grip, a clamp or other parts, the device is convenient, light in weight and practical.

A cable light includes a battery receptacle that is electrically coupled to a first light module and a second light module. The battery receptacle includes a battery port that receives and retains a battery, such as a power tool battery pack. The first light module and the second light module each include a housing supporting a lens, a light emitter such as an LED, a reflector, and a hanger to hang the light modules on a workpiece. The first light module is electrically coupled to the battery receptacle, and the second light module is electrically coupled to the battery receptacle via a connection with the first light module. The battery receptacle communicates electrical power from the battery pack to the light modules to power the light emitters.

The hand held flat flash light about the size of a cell phone with a 1 degree lens collimator, a rechargeable battery contained in the body, an on/off switch and one or more LED's that emit a high energy beam of light or spot light.

Disclosed is a luminous necklace structure. The present invention adopts the following technical solution: a luminous necklace structure, comprising a battery case; a chain rope with both ends connected with the battery case; pendant(s), at least one of which is connected with the chain rope, so that the battery case can supply power to the chain rope and make the pendant(s) luminous. The beneficial effects of the present invention are as follows: the chain rope and the light shade adopt diversified connecting methods which are more flexible and convenient for use, the movable connection between the light holder and the light shade makes the luminophor changeable, thus prolonging the service life of the luminous necklace and meanwhile saving the costs, and the same luminous necklace is allowed to be provided with either luminous or non-luminous light shade, thus enhancing the luminous effect of the necklace.

A portable light may comprise: a light body; a light source, an electrical switch for selectively energizing the light source, the light body having an opening through which the electrical switch can be actuated. A pivot pin pivotably mounts an actuator having an actuation feature that extends towards the opening for actuating the electrical switch when pivoted towards the light body. The light body has a receptacle in which the pivot pin is removably disposed. A retainer of a resilient material resiliently retains the pivot pin in the receptacle and resiliently deforms for removal of the pivot pin therefrom; whereby the actuator is removable and replaceable on the light body by removing the pivot pin. The light body may have a seal of resilient material in the opening of the light body. A user formable actuator of a curable material may be provided.

A wearable electronic device including: a first portion and a second portion. The first portion includes a first conductive area on a first inner surface of the first portion and a third conductive area on a first outer surface of the first portion. The second portion includes one or more second conductive areas on a second outer surface of the second portion and a fourth conductive area on a second inner surface of the second portion, wherein the first portion is connected to the second portion. A circuit unit is disposed in a second space of the second portion, wherein the circuit unit is configured to enable an input/output unit of the circuit unit in response to the first conductive area and the second conductive areas are triggered.

A high-efficiency lamp, emitting light from a front surface, and having a high-efficiency light source, producing a first light beam. An iris assembly has an annular body that defines a first annulus and has iris blades which can be extended into the annulus to form a second, smaller, annulus. This iris assembly is positioned relative to the light source so that the iris blades are in front of the high-efficiency light source. The annular body and therefore the first annulus have finite depth from back to front. A light guide is placed immediately behind the iris blades and defines a channel that is open at its back and its front and has a reflective interior surface, with the open back being transversely coincident to the light source so that light from the light source can travel through the channel to and out from the open front.

To provide an air passage for torch combustion in the torch main body to ensure the freedom of design. A decorative elongated object according to the present invention includes an elongated material (100) with a cross section having a plurality of radial lines (L2) and being uniform from one end (1a) to another end (1b), a cavity being formed at the center of the elongated material, in which the elongated material has a side surface at least partially tapered to be thinner toward the other end (1b) from the one end (1a), with the radial lines (L2) partially cut and removed along a side surface cutting plane intersecting with the side surface.
