Disclosed is a laser emitting dart apparatus (LEDA) and method of use. The LEDA provides for a dart apparatus that, by emitting a laser beam from a tip of the dart and projecting a laser dot onto a selected target, facilitates a dart user’s aim by providing an indication of where the dart is likely to strike a selected target if the dart is thrown or projected in a substantially straight line from point of the user’s grasp to the indicated laser dot projected onto the target. The invention further contemplates various charging cases or dart cradles that provide an electrical source to recharge a battery of the LEDA when the LEDA is not in use.

Apparatus for generating a line-beam includes a diode-laser bar, a linear micro-lens array, and a plurality of lenses spaced apart and arranged along an optical axis. The linear micro-lens array and the lenses shape laser-radiation emitted by the diode-laser bar to form a uniform line-beam in an illumination plane. The lenses project a far-field image of the diode-laser bar onto an image plane proximate to the illumination plane. The diode-laser bar is rotated from parallel alignment with the linear micro-lens array for providing uniform line-beam illumination over a range of locations along the optical axis.

A laser pointer accessory having a housing and a laser diode assembly including an actuation button. The housing including a top and bottom surface, and an internal chamber such that the laser diode assembly is disposed within the internal chamber of the housing. The top surface of the housing including an actuator capable of being depressed such that it engages the actuation button in order to activate the laser diode assembly.

A multi-mode remote control unit that has both infrared command and laser pointer capability. In some examples, the multi-mode remote control unit together with one or both of a television receiver and a television may implement simulated touch gestures that typically require a touch sensitive screen. The multi-mode remote control unit in such an implementation advantageously may not include logic to implement simulated multi-touch gestures. Rather, one or both of the television receiver and the television may include logic to implement simulated touch gestures.

A structured light projector for generating a far-field image of light dots in a defined pattern is proposed, where the structured light projector includes a light source providing as an output a non-collimated light beam and a specialized diffractive optical element disposed to intercept the non-collimated light beam. The specialized diffractive optical element is formed to exhibit a non-uniform pattern of grating features configured to compensate for the non-planar wavefront and phase retardation of the non-collimated output beam, providing as an output of the projector an interference pattern of light dots exhibiting the desired configuration.

Disclosed is a dart game system which is capable of providing a laser lighting effect. The dart game system includes a dart game apparatus and a laser lighting apparatus, in which the dart game apparatus includes: a dart target which includes a plurality of segments and which a thrown dart pin hits, the plurality of segments including a plurality of receiving recesses for receiving respective thrown dart pins, each segment being set with a score corresponding to a position of each segment in the dart target; a sensing unit which detects a segment hit by the dart pin among the segments included in the dart target; and a controller which detects a hitting position of the dart pin at least partially based on a signal received from the sensing unit, progresses a dart game based on the hitting position of the dart pin, and controls the laser lighting apparatus, and the laser lighting apparatus is disposed at a position, at which the laser lighting apparatus radiates a laser to each segment of the dart target, and provides the laser lighting effect to the dart pin at least partially based on a determination of the controller.

A laser lighting device configured to provide two levels of image adjustment. An end piece provides first range of motion along the longitudinal axis of the laser, and controls image size projected from the laser. The end piece also allows for a number of masks to be utilized with the laser so that the projected light may be projected in various images shapes. A cap piece is rotatable about the longitudinal axis of the laser and may create various patterns in the light being projected, such as spots sparkles, and other patterns, or fill textures to the projected image of variable size.

One or more excitation energy sources emit light in an excitation spectrum and direct the emitted light as an excitation beam to the emitting surface of a wavelength conversion element directly or via reflection. Distinct areas of the emitting surface are coated with one or more distinct fluorescent phosphors. The phosphor-coated areas receive the excitation beam and generate a sequence of fluoresced light beams at a light output, each fluoresced beam of a narrow spectrum determined by the type of phosphor and the excitation spectrum. The fluoresced beams travel parallel to an emitting axis at a non-zero angle to axes associated with the excitation beams.
