The portable flashlight apparatus includes a base housing defining an interior space and which includes structurally defined regions that include a front housing region, a rear housing region, an intermediate housing region extending between the front housing region and the rear housing region and an end cap that closes the interior space at the rear housing region. A light module includes a first light source operable to emit illuminating light, a second light source operable to emit laser light, and a third light source operable to emit illuminating light. A magnet are arranged at the rear face of the end cap, and is operable to magnetically bias the base housing on a working surface or support surface having magnetic properties.

A signaling device is disclosed comprising an electronic circuit positioned within a housing and comprising at least one LED, a light diffuser manufactured from a non-opaque material and a USB Port. Side edges of the housing each comprise a barb engaging slot therein. A cap end covering the USB port and comprising a pair of flexible fingers each comprising a barb-like feature for engaging respective ones of the barb engaging slots comprises an actuating part fabricated from a compressible rubberlike material which is secured towards a second end of each of the flexible fingers. Compressing the actuating part motivates the outer ends of the flexible fingers to move apart, thereby releasing the barb-like features from their respective barb engaging slot and allowing the cap to be removed from the housing.

An elliptical lens comprises a lens body having a proximal section and a distal section. The proximal section has at least one input surface for receiving light from a light source and the distal section has at least one output surface through which light exits the lens body. The proximal section further comprises a substantially elliptical peripheral surface receiving at least a portion of the light entering the lens body via the at least one input surface and directing at least some of the received light via total internal reflection to the distal section such that at least a portion of the light directed to the distal section exits the lens body through said at least one output surface. Optical assemblies having said elliptical lens may be embedded in medical devices such as endoscopes to provide efficient illumination.

The present disclosure discloses a battery box lamp wire installation structure, which relates to the technical field of power supply devices and it comprises a case, provided with an accommodating cavity inside; a printed circuit board, horizontally located in the accommodating cavity and fixedly connected with the case; an end cap, movably mounted on one end of the case, and the end cap is provided with a wire hole A; a lamp wire, of which one end penetrating through the wire hole A and restrained within the end cap; a connector, detachably mounted at the inner side of the end cap and fixing the positive and negative ends of the lamp wire; the positive and negative ends of the lamp wire are in electrical connection with the printed circuit board respectively when the end cap is mounted onto the case.

A remote control for operating a light system having a light source housed in a light housing, a power source, and a manual switch that can selectively activate a light source comprising a tail cap configured to couple to the light source, wherein the tail cap has a housing that houses a microcontroller and a wireless communication module, wherein the microcontroller can be coupled to the wireless communication module and to the light source such that the microcontroller can operate to selectively control the light source when the tail cap is coupled to the light source. A remote having a communication interface wherein the communication interface can communicate with the wireless communication module wherein the communication interface receives user preference information from the remote to allow the user to remotely control the light source.

A night hunting spotlight has a fixed lens, a fixed bezel, and a light-emitting diode (LED) movable in relation to the fixed lens so as to broaden or narrow the beam, respectively. The LED may be movable using telescoping mechanisms, rotating mechanisms, knobs, linear actuators (manually actuated or electronically controlled), or other mechanisms capable of moving the LED along the longitudinal axis of the night hunting light to approximate the lens or move distally therefrom.

In one aspect, a light module is disclosed, which includes a housing providing a hollow chamber extending from a proximal end to a distal end, and a lens positioned in the hollow chamber, where the lens has a lens body comprising an input surface for receiving light from a light source and an output surface through which light exits the lens body, said lens further comprising a collar at least partially encircling said lens body. The light module further includes at least one shoulder on which the lens collar can be seated for positioning the lens within the housing. A light source, e.g., an LED, is coupled to the hollow chamber, e.g., at its proximal end, for providing light to the lens.

An illumination source, comprising: (a) at least one coherent light emitting device (CLED) configured for emitting coherent light having an optical path; (b) at least one optical element in said optical path for converting at least a portion of said coherent light to incoherent light, said optical element being configured to emit said incoherent light in a direction; and (c) a light control mechanism (LCM) for altering said direction of said incoherent light.

A portable lighting device having multiple mounting features providing multiple mounting configurations allowing for hands-free lighting in various situations and locations. The portable lighting device comprises a housing with (i) a front bezel configured to receive a primary optic; (ii) a central support having a securement means and a peripheral segment configured to receive an extent of a cap of a bottle; and, (iii) a rear body having a multi-positional assembly, a coupling means residing within the multi-positional assembly, and a mounting means. The lighting device also includes an illumination assembly having a light source configured to emit light beyond the housing to illuminate a surrounding area, and a power source disposed within the housing and operably coupled to the illumination assembly. The multi-positional assembly is movable between a retracted position and a deployed position that improve the utility of the portable lighting device.
