LASER DECORATIVE LIGHTING FOR PROJECTING LASER
The present invention is applicable in the technical field of laser lights, and provides a laser light for projecting laser which comprises a color adjustable laser light source and a dimmer, the dimmer comprises a rotator having a convex surface and a micro lens array arranged on the convex surface, and the micro lens array is formed by a plurality of closely arranged micro lens; each of the micro lens reflects the laser irradiating on a surface thereof so as to form a light spot on a light receiving surface, the rotator can rotate axially, such that the micro lens array can reflect an incident laser dynamically and scatteringly so as to form a light spot pattern having the same color with that of the incident laser on the light receiving surface.
LIGHT EMITTING DEVICE
A light emitting device includes one or more light emitting elements, a light transmissive member, a first light reflective member and a second light reflective member. The light transmissive member is disposed on the one or more light emitting elements and having a first upper surface, a lower surface, first lateral surfaces, and second lateral surfaces each positioned on an outer side of a corresponding one of the first lateral surfaces. The first light reflective member covers the first lateral surfaces. The second light reflective member is disposed on lateral surfaces of the first light reflective member, the second lateral surfaces of the light transmissive member, and lateral surfaces of the one or more light emitting elements.
Light-source optical system, fiber light source, microscope, and automotive headlight
A light-source optical system according to the present invention includes a laser light source that radiates excitation light; a wavelength conversion unit that is irradiated with the excitation light to generate light having a wavelength different from that of the excitation light; and a light deflection and convergence unit that causes an odd number of light beams greater than or equal to three, radiated from the wavelength conversion unit in mutually different directions, to converge at and re-enter the wavelength conversion unit from the backward direction of another light beam, radiated in a direction different from the directions of the odd number of light beams greater than or equal to three, thereby making the odd number of light beams greater than or equal to three overlap the other light beam.
DECORATIVE LIGHTING DEVICE AND GAME MACHINE
It is an object of the present invention to provide a decorative lighting device and a game machine, with which the brightness of a light presentation can be increased and a light presentation with a more dramatic effect can be given even if the number of light sources is limited. A decorative lighting device (1), which has an elongated shape in the vertical direction and is installed on both sides of a game machine, comprises a case (2) in which at least the front and side surfaces of the device are open; a transparent cover (3) that covers the open portion of the case (2); a plurality of light guide plates (4S, 4M, 4L) that are housed inside the case (2) and are disposed spaced apart in the front-rear direction of the device, with each light emitting surface (4a) facing the front surface of the device; and a plurality of light sources provided corresponding to the plurality of light guide plates (4S, 4M, 4L).
Luminaires having a wireless antenna
A luminaire includes a housing defining an interior volume. The luminaire also includes a lamp within the interior volume and configured to emit light. Additionally, the luminaire includes a wireless antenna positioned within the interior volume, configured to transmit or receive a wireless signal along a first direction, and configured to be operatively coupled to an access point. The wireless antenna can be entirely within the interior volume. The luminaire can include a first reflective surface within the interior volume and configured to redirect the wireless signal. The lamp can be configured to be electrically coupled to a power inserter that powers the access point.
Illuminating device and projector
An illuminating device may include a light source, an optical unit configured to adjust direction of light from the light source, a reflector, a light pipe, and an exciter. The light pipe may receive light having a first wavelength from the optical unit and direct the light having the first wavelength onto the exciter. The exciter may convert the light having the first wavelength into light having the second wavelength and reflects the light having the second wavelength to the reflector. A circumferential wall of the light pipe is configured to reflect the light having the first wavelength and to transmit the light having the second wavelength.
ILLUMINATING DEVICE
An illuminating device includes a light source having a light-source optical axis, a lens that is located substantially parallel to the light-source optical axis such that a surface of the lens faces the light-source optical axis, the lens extending to a position rearward of the light source in a direction of the light-source optical axis, and a light reflecting portion located so as to be opposed to a front side of the light source, the light reflecting portion being adapted to reflect emitted light of the light source obliquely rearward of the light source, and reflect the emitted light toward the lens.
Planar lighting device
A display device including a lower cover; a circuit substrate on the lower cover; a plurality of light sources disposed on the circuit substrate; a reflection layer disposed on the lower cover; a light regulating pattern disposed close to an edge of the reflection layer; and an optical sheet disposed on the light sources. Further, the light regulating pattern changes in size as a distance from the light source changes.
Lighting device having a light source heat sink arranged separate from a driver
A lighting device (1) comprising a driver (7) arranged at a base (2) of the lighting device (1), a heat sink (14) arranged at a portion (3) of the lighting device (1), separate from the driver (7), a light source (13) mounted to the heat sink (14), and a wire (10) arranged to electrically connect the light source (13) to the driver (7), wherein a portion of the wire (10) extending from the base (2) to the portion of the lighting device (1) is arranged to be exposed to light from the light source (13). The present embodiment is advantageous in that the thermal performance is improved and the lifetime of the lighting device (1) is increased. Further, the exposed wire (10) may be illuminated by the light source (13) and visible from outside the lighting device (1), thereby having the appearance of a filament.
