摘要： A lighting apparatus includes a light source module, a light passing cover, a prism plate and a surface rim. The light source module includes a light source plate and multiple LED modules mounted on the light source plate. The light passing cover has a first side facing to the multiple LED modules for receiving a light from the multiple LED modules. The prism plate is disposed with more than 50 prism units for diffusing the light passing through the light passing cover from a second side of the light passing cover. The surface rim has a light opening for the light diffused by the prism units to escape from the lighting apparatus.

摘要： An irradiation unit is disclosed that includes a pump radiation source for emitting pump radiation in the form of a beam, a conversion element for at least partially converting the pump radiation into conversion radiation, and a support on which the conversion element is situated. The support accommodates a through-hole through which the beam including the pump radiation is incident on an incident surface of the conversion element, the though-hole being laterally delimited by an inner wall face of the support, at least one portion of the face tapering in the direction of the incident surface. During operation, the pump radiation conducted in the beam is at least intermittently at least in part, incident on the inner wall face of the support and is reflected thereby onto the incident surface.

摘要： A laser-excited-phosphor light-source system in which a phosphor plate remains stationary while a laser beam is made to scan across the phosphor plate. In some embodiments, the phosphor-plate assembly includes a plurality of areas each having a different phosphor substance that emits wavelength-converted light in response to excitation from the scanned laser beam and/or a diffusive material. In some embodiments, one or more rotating prisms and/or one or more rotating or oscillating or angularly displaced mirrors are used to deflect the input laser light on the way toward the phosphor plate and to deflect the wavelength-converted and/or diffused light in the opposite direction such that the output beam of wavelength-converted and/or diffused light remains stationary with respect to the phosphor plate as the input laser beam is moved across the surface of the phosphor-plate assembly.

摘要： There are provided a backlight assembly (1) and a display device, the backlight assembly (1) includes a light source substrate (10), a microstructure film layer (30) and a backlight film material layer (20); the backlight film material layer (20) is located on a light outgoing side of the light source substrate (10), the microstructure film layer (30) is provided between the light source substrate (10) and the backlight film material layer (20), the microstructure film layer (30) includes a light transmission layer (301) and a microstructure region (302); the microstructure region (302) is provided at an edge position of the microstructure film layer (30). The combination of the microstructure region (302) and the light transmission layer (301) can change, at the edge position, an outgoing angle of all or part of backlight passing through the microstructure region (302), so that all or part of the backlight passing through the microstructure region (302) is deflected from a direction perpendicular to the edge where the microstructure region (302) is located and is refracted away from a center of the microstructure film layer (30), thereby an optical path of the backlight with the changed outgoing angle when passing through the backlight film material layer (20) is increased, more red light and green light are excited, and thus a problem of uneven chromaticity of a bluish edge of the backlight during full screen displaying is solved.
