摘要： A light-emitting module includes a light-emitting plate including a light-irradiating surface including a plurality of striped-pattern light-emitting units, and a reflecting member including a reflecting surface to reflect light emitted from the light-irradiating surface of the light-emitting plate toward a target surface of an object. Light at a peak luminous intensity in a light distribution in a first region of the light-irradiating surface is sent to a first region of the target surface via a first region of the reflecting surface. Light at a peak luminous intensity in a light distribution in a second region of the light-irradiating surface is sent to a second region of the target surface via a second region of the reflecting surface.

摘要： A light emission device includes a light source that emits an excitation light beam, a light deflector, a wavelength converter that receives and converts the excitation light beam deflected by the light deflector to wavelength-converted light, and a light concentration section that focuses the excitation light beam on the wavelength converter. The light concentration section includes a first optical system disposed between the light source and the light deflector, and a second optical system disposed between the light deflector and the wavelength converter. In the second optical system, a focal length of an Ay-axis is shorter than a focal length of an Ax-axis, where the Ax-axis is defined as an axis that has a lowest beam parameter product of the excitation light beam, and the Ay-axis is defined as an axis orthogonal to the Ax-axis in a cross section perpendicular to a propagation direction of the excitation light beam.

摘要： A light-emitting device and a projection system, comprising: a laser array light source which comprises a non-light-emitting region and a light-emitting region consisting of a plurality of laser elements; a reflective light-condensing system which comprises a light-condensing region and a non-light-condensing region, wherein the light-condensing region is used for focusing and reflecting emergent light of the laser array light source; and a light-collecting system used for collecting and emitting the emergent light from the reflective light-condensing system. The light-collecting system, the non-light-emitting region and the non-light-condensing region are located in the same straight line parallel to a light axis of the emergent light of the laser array light source, and the light-collecting system passes through the non-light-emitting region and/or the non-light-condensing region. The light-emitting device and the projection system have small volumes and can emit high-brightness and uniform faculae.

摘要： A lighting device includes at least one excitation radiation source designed to emit excitation radiation; a wavelength conversion arrangement, which is arranged in such a way that excitation radiation can be radiated onto a wavelength conversion element. The wavelength conversion element is designed to convert excitation radiation into conversion light. An unavoidable non-converted part of the excitation radiation is reflected by the wavelength conversion element. The device further includes a unit for collimating the excitation radiation to form at least one collimated excitation beam; a unit for directing the at least one collimated excitation beam onto the at least one wavelength conversion element; a unit, which is arranged between collimation optical unit and converging optical unit and has at least one region for reflecting that part of the at least one excitation beam which is not converted, but rather is reflected by the at least one wavelength conversion element.
