An illuminator and a display capable of achieving miniaturization are provided with use of a plurality of light sources emitting light with two or more kinds of wavelengths. In the light source unit 11, a red-color laser 11R, a green-color laser 11G, a blue-color laser 11B, a microlens section 116, and a microprism 117 are integrated on a base material. Each laser beam emitted from each of the laser light sources is transmitted through the microlens section 116, and then, comes into the microprism 117. In the microprism 117, optical path conversion is performed to shorten the distance between the optical paths of the incident light beams (to allow the optical axes of the incident light beams to be closer to each other). Due to the above-described integration, the optical paths of the laser beams are allowed to be synthesized using the microscopic-scaled microlens section and microprisms.

The lighting device (11) has at least one light generation device (12) for generating a primary light (P), a first luminophore (16) for converting the wavelength of the primary light (P) to a first secondary light (S1), and a second luminophore (20) for converting the wavelength of the primary light (P) to a second secondary light (S2), the first luminophore (16) being located on a movable support (15), which is provided in order to alternatively move the first luminophore into and out of a beam path of the primary light (P), and the second luminophore being located on a stationary support (21). The invention also relates to a method for generating wavelength-converted secondary light from primary light with alternating irradiation of a first luminophore located on a movable support and of a second luminophore located on a stationary support by the primary light. The invention can be used, for example, as a projection device for film and video projection, in endoscopy, for lighting effects in the entertainment industry, for medical irradiations as well as in the automobile industry, in particular as a head light for motor vehicles.

Materials and objects tagged with wavelength selective particles such as SERS nanotags modified for wavelength selectivity. As used herein, a wavelength selective particle is one which cannot be effectively excited or interrogated at one or more wavelengths where a reporter molecule associated with the particle would normally produce a spectrum. Also disclosed are methods of manufacturing wavelength selective particles and methods of tagging materials or objects with wavelength selective particles.

A vehicle light installed in a vehicle includes: a main case having a front opening; a first light guide disposed in the main case; a first light source that emits light into the first light guide; and a headlamp disposed in the main case. The first light guide (i) is rod-shaped, (ii) includes a first extended section extending from the inboard side of the first light guide relative to the vehicle widthwise direction toward the outboard side and a second extended section that continues from the first extended section, curves back inwardly, and extends to the inboard side, and (iii) opens toward a longitudinal center line of the vehicle. The headlamp is disposed between the first extended section and the second extended section. The first extended section and the second extended section extend toward the longitudinal center line of the vehicle to a point beyond the headlamp.

A lighting device includes a light source emitting light having a first bandwidth. A single optic device is coupled to the light source. The single optic device filters light having a preselected subrange of wavelengths within the first bandwidth to generate a first filtered light. The single optic device controls a shape of a beam of the filtered light. The filtered light creates a high-intensity narrow-spectrum light output. A second light source emits a high-intensity narrow-spectrum light output.

A headlamp for vehicles having a projection module containing a first light source for generating a first light bundle, a reflector assigned to the first light source, a lens, and an edge disposed in a focal plane for generating a low beam light distribution. The headlamp also includes a second light source for generating a second light bundle and an optics unit disposed between the lens and the second light source for generating a supplementary light distribution, such that by superimposing the supplementary light distribution and the low beam light distribution, a high beam light distribution is formed. The optics unit is formed by a flat waveguide having a light entry surface for receiving the second light bundle emitted from the second light source. The second light source is disposed in the proximity of the light entry surface, having a light exit surface, and flat sides extending between the light entry surface and the light exit surface, on which entering light can be conducted through total reflection. A light/dark border of the low beam light distribution is formed by the edge of the flat waveguide formed as the front outer edge, which connects the light exit surface and an upper flat side of the waveguide. The upper flat side of the flat waveguide is provided with a light blocking coating, such that an entry of light beams from the first light bundle striking the upper flat side is prevented.

An apparatus for providing a light output to an optical guide for illumination of an imaged object including a plurality of solid state light-emitting sources each of which are independently powered and independently controlled, each light-emitting source emitting light at a wavelength which is different from the wavelength emitted by the other light-emitting sources. The apparatus also includes a heat sink configured to thermally couple the plurality of solid state light-emitting sources and provide conduction of heat generated by the plurality of solid state light-emitting sources. The apparatus further includes an optical elements to collect, collimate, and combine the emissions from the plurality of solid state light-emitting sources into a combined beam of light to be optically coupled to the light guide.

A projection device including a light source system having an excitation light source for generating a excitation light, a wavelength conversion device, a supplemental light source for generating a supplemental light, a light introducing device for directing the supplemental light to the wavelength conversion device, a light collection device for collecting the supplemental light that scattered and reflected by the wavelength conversion device. By setting the relative sizes of the light introducing device and the light collection device, the luminous flux of the supplemental light that is lost due to the light introducing device is less than or equal to a quarter of that the luminous flux of the supplemental light collected by the light collection device. The converted light is supplemented by the supplemental light.
