Abstract: A package structure includes a carrier, a housing, an edge-emitting laser, first and second reflective members and a diffractive optical element. The housing disposed on a mounting surface of the carrier has a receiving space and a top surface, which has an opening and a center line perpendicular to the top surface and the mounting surface. The edge-emitting laser disposed in the receiving space and on the mounting surface has a light-emitting surface emitting a laser beam. The first reflective member is disposed in the receiving space and spaced apart from the light-emitting surface. The second reflective member is disposed in the receiving space and located on the center line above the edge-emitting laser. The diffractive optical element is disposed on the top surface. The laser beam reflected by the first and second reflective members passes through the diffractive optical element to emit out of the housing.

Abstract: The invention relates to an encapsulated optoelectronic component having a housing and at least one optoelectronic component, which is arranged in a cavity which is formed by a main element and is covered on an upper side by a cover element, and therefore the optoelectronic component is arranged between the cover element and the main elements and the main element forms side walls which laterally enclose the cavity. A one-part plate element with at least one tongue-shaped deflecting element is arranged between the cover element and the main element in such a way that, in the cavity, the deflecting element is arranged with at least one optical surface by which electromagnetic radiation emitted or received by the optoelectronic component can be deflected. The invention also relates to at least one wafer with deflecting elements, to a composite assembly of encapsulated optoelectronic components and to a method for the production thereof.

The laser device includes parts involved in the following: A bottom plate of a housing covers a bottom end of a housing body, and the bottom plate includes a first conductive region and a second conductive region apart from each other. An inner cavity of the housing body and the bottom plate form a mounting cavity with a light outlet opposite the bottom plate, and the mounting cavity is provided in a light source assembly. A side surface of the light source chip facing the light outlet is a light-emitting surface, and light is projected from the front of the light outlet. The technical solution provided by this application is to attach an edge emitting source chip onto the mounting side surface of the support member, so as to achieve frontward projecting.

Abstract: The laser device includes a substrate, a laser element disposed on the substrate for emitting a laser light ray, a light guide member disposed on the substrate, and a wavelength conversion layer. The light guide member is light-transmissible and thermally conductive, and has at least one reflection surface for reflecting the laser light ray from the laser element so as to change travelling direction of the laser light ray. The wavelength conversion layer converts wavelength of the laser light ray from the light guide member to result in a laser beam, and contacts the light guide member so that heat from the wavelength conversion layer is transferred to the substrate through the light guide member.
