Lighting devices that comprise a light source and a reflector, the reflector comprising first, second and third reflector regions. In some devices, a first portion of light is reflected by the first region and then by the third reflector region, a second portion of light is reflected by the second region and forms a primary beam, and at least 5% of the first portion of light that is reflected by the third region is within the primary beam of light. In some devices, at least 5% of all light reflected by the first reflector region travels from the first reflector region directly to the third reflector region. In some devices, at least 5% of all light reflected by the third reflector region traveled directly from the first reflector region to the third reflector region. In some devices, the reflector comprises means for providing the features described above.

An illuminating device according to the present disclosure is of a reflective type and uses a laser beam. The illuminating device includes: a laser element that emits a laser beam; an optical fiber that transmits the laser beam emitted by the laser element; a phosphor layer that converts a wavelength of light incident on one of surfaces and emits the light through the one of the surfaces; and an optical component that causes reflected light of the laser beam transmitted through the optical fiber to be incident on the one of the surfaces of the phosphor layer. With the illuminating device, an intensity distribution of the light incident on the one of the surfaces of the phosphor layer is sparse at a central region.

A modular light emitting diode (LED) mounting configuration is provided including a light source module having a plurality of pre-packaged LEDs arranged in a serial array. The module includes a heat conductive body portion adapted to conduct heat generated by the LEDs to an adjacent heat sink. As a result, the LEDs are able to be operated with a higher current than normally allowed. Thus, brightness and performance of the LEDs is increased without decreasing the life expectancy of the LEDs. The LED modules can be used in a variety of illumination applications employing one or more modules.

A lighting assembly comprising a light source operable to emit light, a first primary optic, and a second primary optic. Each of the first primary optic and the second primary optic are configured so as to reflect light incident thereupon to be emitted by the lighting assembly. Additionally, each of the first primary optic and the second primary optic are positioned such that a first portion of light emitted by the light source is incident upon the first primary optic and a second portion of light emitted by the light source is incident upon the second primary optic. At least one of the first primary optic and the second primary optic is operable to me rotated to change the relative position thereof with respect to the light source.

An exterior aircraft light unit includes a mounting structure, an LED arranged on the mounting structure, and an optical system, arranged on the mounting structure for creating an output light emission distribution of the exterior aircraft light unit. The optical system has, in a first cross-sectional plane extending through the LED, a first concave reflector and a second concave reflector, each of the first and second concave reflectors having a proximate end positioned adjacent to the mounting structure and a distal end positioned removed from the mounting structure, with the first and second concave reflectors being arranged on opposite sides of the LED in the first cross-sectional plane, and a refractive optical element arranged between the first and second concave reflectors in the first cross-sectional plane. The distal ends of both the first and second concave reflectors that curve towards each other and have back-tapered shapes.

The present invention is directed to an apparatus for providing a light reflector, light fixture, light fixture retrofit apparatus, lamp reflector, lamp retrofit apparatus or luminaire reflector retrofit. According to an example embodiment of the disclosed invention, a light reflector is provided that includes annular segments nested as cone-shaped layers configured for reflecting light from a light source placed in proximity to the inner cone portion. The two or more nested cone-shaped annular segments include a reflective surface. The cone-shaped annular segments are configured such that the segment layer having the smallest aperture is located farthest from the light source.

A lighting device contains light-emitting elements and has an elongated shape. The lighting device has a housing that has reflective side walls extending in a longitudinal direction of the housing; a cavity formed between the reflective side walls; and light-emitting elements arranged at least partially along the longitudinal direction relative to each other in the cavity. An opening of the cavity forms a light-emitting area, A width of the cavity expands from the light-emitting elements towards the opening at least in sections. A reflective element covers at least a section of the opening and reflects a part of light emitted from the light-emitting elements towards the cavity and reduces a width of the light-emitting area compared to a width of the opening.

A headlamp for vehicles having a light source, a lens unit and a liquid crystal shutter arranged between the light source and the lens unit. The liquid crystal shutter includes a multitude of surface areas that can each be controlled to switch the respective surface areas to a transparent or a non-transparent state so that a given light distribution pattern is generated. A polarizing reflector is assigned to the light source, so that a linearly polarized light beam is reflected in the direction of the liquid crystal shutter.
