LED lighting lamps provide optimum heat dissipation efficiency, wide illumination beam angles, and substantially uniform illumination intensity. Generally, the disclosed LED lamps comprise at least one LED lighting element and a substrate with a plurality of inclined planes.

An LED light source assembly for signage illumination includes one or more planar LED arrays located with respect to a light spreading system for uniformly distributing light onto a viewing surface. The light spreading system includes a plurality of reflectors in combination with a transverse deflector disposed directly above and in the light emanating path of a planar LED array. The transverse deflector is oriented angularly and projects at least a portion of light onto a lateral reflector of the light spreading system. In one embodiment, a heat dissipation fixture is supported external to a housing assembly for improved heat management. The LED arrays and the plurality of reflectors and transverse deflectors are affixed directly to the heat dissipation fixture.

A luminaire comprising a housing, plurality of reflectors, lamps and electrically connected lamp sockets. The luminaire has at least two asymmetrical reflectors that are symmetrically opposed to each other and ideally has at least one symmetrical reflector located between the asymmetrical reflectors.

A high efficiency refraction body includes a light source chamber and a main refraction surface opposite to the light source chamber. A first refraction surface and a second refraction surface for refracting the lights are formed to a peripheral of the high efficiency refraction body. A light source is received to the light source chamber. Lights from the light source will be total reflected because the incident angles of the lights exceed a critical angle of the main refraction surface. The reflected lights will be refracted through the first refraction surface and the second refraction surface so as to pass a lateral of the refraction body. A uniform lateral illumination of the refraction body will correct the poor lateral illumination of LED light devices.

A first lamp unit includes a plurality of first light-emitting elements arranged in a vehicle width direction. A second lamp unit includes a plurality of second light-emitting elements arranged in the vehicle width direction. A wiring channel of a first type lights at least one of the first light-emitting elements by supplying power thereto, thereby forming a light distribution pattern of a first type. A wiring channel of a second type connects at least one of the first light-emitting elements in series with at least one of the second light-emitting elements, and lights these by supplying power thereto, thereby forming a light distribution pattern of a second type. The position of a light-dark boundary that extends vertically in the light distribution pattern of the first type is different from the position of a light-dark boundary that extends vertically in the light distribution pattern of the second type.

A vehicle light can form a synthetic light distribution pattern with an area where a surrounding vehicle exists being made darker than an area(s) surrounding that area. The synthetic light distribution pattern can allow a sufficient illumination range and a center light intensity required for a running beam to be compatible. The vehicle light can also form a light distribution pattern with only an area where a farther surrounding vehicle exists is made dark. The vehicle light can form the light distribution pattern by overlaying a plurality of first nearby illumination areas, a plurality of first farther illumination areas, a plurality of second nearby illumination areas, and a plurality of second farther illumination areas with the respective illumination areas being divided in a horizontal direction and individually controlled in terms of light intensity so that respective vertical division lines of the illumination areas appear in predetermined order in the horizontal direction.

An image capture device, which illuminates a subject and receives light reflected from the subject to capture an image of the subject, is provided to achieve a small-size configuration and easy assembly. A plurality of light-emitting elements are mounted in positions on the periphery of an image sensor, and a light-guiding member guides light from the plurality of light-emitting elements to the image capture range for illumination. And protrusions of the light-guiding member are pressed by the lower end of a hood which blocks light from outside the image capture range, and the hood upper end is pressed by a filter. Slits are provided in the hood lower end. Even in assembly where a visible light filter is installed on the hood and fixed to an outer case, the occurrence of gaps between the hood and the visible light filter can be prevented through the spring action of the slits.

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.

An imaging device includes: an illumination portion which includes a light-transmitting transmission region and a light-shielding non-transmission region, has a plurality of simultaneous light-emitting elements that have a light-transmitting property, include a plurality of first light-emitting elements in which turning-on and turning-off are simultaneously controlled and a plurality of second light-emitting elements in which turning-on and turning-off are simultaneously controlled, and are provided in the transmission region, and has a plurality of individual light-emitting elements in which turning-on and turning-off are individually controlled and which are provided in the non-transmission region; an imaging portion which receives light that is reflected from a subject illuminated by the illumination portion and is transmitted through the transmission region; and a switching portion which selectively turns on the plurality of first light-emitting elements and the plurality of second light-emitting elements in a first period in which the plurality of individual light-emitting elements are turned off, and turns off the plurality of simultaneous light-emitting elements in a second period in which the plurality of individual light-emitting elements are turned on.

A laser transmitter projects a beam of laser light outward while raising and lowering the beam. The beam may define a conical surface of varying inclination. The transmitter includes a laser source that directs a beam generally vertically, and a beam diverting element. The beam diverting element is positioned in the path of the beam, intercepting the beam and redirecting it. The beam emerges from the transmitter as a non-vertical beam that is raised and lowered. The diverting element may include a pair of mirrors configured as a pentaprism, with one of the mirrors pivotable. Alternatively, the diverting element may include a plurality of micro mirrors. Also, the diverting element may include a conical reflector and an annular lens which is cyclically raised and lowered. The beam may be raised and lowered cyclically according to a predetermined schedule, or it may be raised and lowered non-cyclically.
