Abstract: A laser target pointer comprises a case, a lighting module, a laser module, an operating module, an adjustment mechanism and a magnetic switch. The adjustment mechanism is equipped with a biaxial pivoting mechanism to adjust the position of the laser aiming point of the laser module. The magnetic switch can be magnetically attracted and detachably connected with a contact block and electrically connected to the laser target pointer. The power of the laser target pointer can be conveniently turned on or off by operating the magnetic switch. The lighting module comprises a plurality of invisible light emitting diodes having different divergence angles in order to provide different irradiation distances. The operating module comprises a plurality of luminous patterns each corresponding to an operation function, such that the user can clearly and quickly identify which one of the operation functions is currently enabled.

Abstract: A laser target pointer for engaging a gun includes a body, a locating plate, a positioning block, a first fitting element and an adjustable positioning assembly. By providing the adjustable positioning assembly, the laser target pointer can be clamped to a gun with an arbitrary body width. By adjusting a position of the positioning block with respect to the locating plate, the laser target pointer can be positioned to a gun with an arbitrary transverse positioning groove. Thus, the laser target pointer can be properly assembled to any gun body having specifications within a predetermined range, and the position of the laser target pointer can be adjusted on the gun body in the extension direction, such that a single laser target pointer can be applicable to various guns with different brands, types, series or specifications.

Abstract: The present invention provides an improved structure of laser sight, which comprises a sight body, a block, a displacement adjusting device, and a switch. The block can be disposed flexibly to locations on one side of the sight body for fitting different type of firearms. The displacement adjusting device can control the location of a laser module inside the laser sight for changing the location of light emission of the laser module and modifying the location of the laser module. The switch is used for controlling the laser module and improving the convenience in control. By using the structure described above, the laser sight will have better practicability and sighting performance.

Abstract: A twin-beam laser module has a housing having a first cylindrical space and a second cylindrical space, which are adjacent and parallel in axial direction to each other. A first laser assembly is directly secured inside the first cylindrical space to output a first laser beam, and an outer cylindrical casing is positioned inside the second cylindrical space. A second laser assembly is provided inside the outer cylindrical casing to output a second laser beam, and an adjustment apparatus adjusts the orientation of the outer cylindrical casing so as to align the first laser beam and the second laser beam to be parallel to each other.

Abstract: A focused lighting device has a plurality of light sources, each of which emits a light beam, and a focusing cup. The cup has a cup body with an opening at its top, a reflective hood positioned in the cup body and defining a plurality of reflective mirrors, with each mirror corresponding to a separate one of the light beams emitted from the light sources to reflect the corresponding light beam emitted from the light sources, so as to simulate a central light source focused in the focused cup. The focused lighting device can also include a plurality of partitions, with each partition positioned between adjacent reflective mirrors to separate the light beams emitted from the light sources so as to prevent the light beams from projecting onto non-corresponding reflective mirrors. The focused lighting device can further include a hood body disposed at the top opening of the focusing cup and having a plurality of parallel light guides.

Abstract: A gun accessory includes a main body having an upper surface having two sides, a first side wall and a second side wall extending upwardly from each of the two sides, first and second slide members provided on the first and second side walls, respectively, and a first locating hole provided adjacent the first side wall. The accessory also includes a first locating bar pivotably coupled to the first locating hole and having a first baffle and a first press plate, and a first elastic element provided between the first press plate and the main body to pivot the first press plate with respect to the main body, and in turn drive the first baffle to protrude above the upper surface of the main body.

Abstract: A semiconductor chip package has a pillar body including at least three conductors insulated from each other by an insulating layer. The pillar body has a periphery that includes a plurality of mounting faces, with each mounting face defined by two adjacent conductors separated by a portion of the insulating layer. A plurality of semiconductor chips are attached on the mounting faces and selectively and electrically connected to the conductors. The semiconductor package of the present invention can be used in a semiconductor illuminator which has a housing having a reflecting cup, with the pillar body positioned inside the reflecting cup.

Abstract: A non-contact electronic level has a light source, a vial having a bubble and positioned to be irradiated by light from the light source, and a photo sensor located at a position corresponding to the bubble at a fixed distance from the vial. The photo sensor captures an image of the bubble after the vial is irradiated by the light source. An image processing unit is electrically coupled to the photo sensor and converts the image of the bubble into an electronic level signal by comparing the centroid of the image of the bubble with a predetermined point.

Abstract: A polygonal prism receives at least one incident light and generates at least one outward light. The prism includes a plurality of planes, with the prism made from one piece of material.

Abstract: A lens is provided for converting a laser beam into laser lines of uniform brightness. The lens has an emission plane through which the laser beam passes, the emission plane having a continuous incline. There is also provided a method for designing the lens.
