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 lighting source structure has a base having at least one electrode coupled to a power source and a plurality of light sources, with each light source electrically coupled to the electrode to produce light when stimulated. The plurality of light sources are arranged on the base in a manner such that the light produced from the plurality of light sources is projected to form a lighted area that has a central focus point which is separate from the locations of each of the plurality of light sources.

Abstract: A connecting device for a weapon accessory has a seat having a sliding rack that removably connects the longitudinal groove of a weapon, and one or more gripping blocks disposed adjacent corresponding side walls of the seat. The gripping block assumes a first position where the gripping block extends inwardly towards the sliding rack to engage a selected transverse groove of the weapon, and a second position where the gripping block extends outwardly away from the respective side wall of the seat to release the longitudinal groove of the weapon. The connecting device also includes a control mechanism operatively coupled to the gripping block. The control mechanism assumes a normal position with the control mechanism controlling the gripping block to maintain the gripping block in the first position, and actuation of the control mechanism causes the gripping block to assume the second position.

Abstract: A method of correcting an optical axis of a laser projecting device is provided. According to this method, a cylindrical tubular member is provided, the tubular member made of a deformable material and having a base section, and a laser generation unit mounted inside the base section and adapted to project a laser beam along an optical axis. The tubular member is also provided with an extension section and a reduced-diameter circumferential groove between the base section and the extension section. Thereafter, the tubular member is rotated while projecting a laser beam from the tubular member towards a reference point in front of the tubular member that corresponds to a rotational axis of the tubular member.

Abstract: Laser systems are provided that include a turntable having a plurality of circumferential mirrors that are rotatably controlled by one motor. One or more laser modules are oriented to direct laser beams at the mirrors, as the mirrors are rotated. Each beam that is reflected by a mirror forms a dot of the desired image. The vertical level of the formed dots is controlled either by providing the mirrors at different angles, or by providing a plurality of laser modules at differently angled orientations or at different vertical positions. The positioning of dots along a horizontal line is controlled by synchronizing the rate of rotation of the turntable with the on-off times of the laser module(s).
