Abstract: A loudspeaker box that is particularly suitable for a hearing aid, includes a cup-like box bottom shell, which delimits a box interior for at least partially receiving a loudspeaker, and a cup-like box cover shell, which, in the intended assembly state of the loudspeaker box, is placed on the box bottom shell overlapping it for a part of its cup height to enclose the box interior and to house the loudspeaker. In the intended assembly state, the box bottom shell and the box top shell form a fluid-tight seal of the box interior in the region of their overlap by the use of a material with increased elasticity relative to the box bottom shell and/or the box cover shell. The box bottom shell and cover shell are reversibly connected to one another in a nondestructively releasable manner.

Abstract: An automotive solid-state headlamp includes a lamp body extending in a longitudinal direction, the lamp body having a rear base portion and a front portion and including a support member and a light-transmissive housing, a plurality of solid-state light sources arranged on the support member at the rear base portion of the lamp body, a drive circuitry electrically coupled to the light sources and arranged at the rear base portion of the lamp body and configured to operate the plurality of light sources when energized and reflector optics arranged at the front portion, wherein the solid-state light sources are configured to emit light towards the reflector optics, the reflector optics including a first reflector optic portion and a second reflector optic portion and wherein each of a plurality of first reflective surfaces disposed on the first reflector optic portion extend in an annular region around the longitudinal direction from the plurality of solid-state light sources towards the first reflector optic p

Abstract: A hearing device has a housing, which is formed with an opening that is acoustically connected to a microphone inside the housing. The hearing device has a lighting unit situated inside the housing, which is optically coupled to a light guide, by way of which the opening is closed. The light guide has a further opening formed inside the opening in the housing.

Abstract: In an embodiment an automotive solid-state headlamp includes a lamp body extending in a longitudinal direction, the lamp body having a rear base portion and a front portion and including a support member disposed in a light-transmissive housing, a plurality of solid-state light sources arranged on the support member at the rear base portion of the lamp body, and a drive circuitry electrically coupled to the light sources and arranged at the rear base portion of the lamp body and configured to operate the plurality of light sources when energized, wherein the plurality of light sources, when energized, are configured to cause the solid-state lamp to emit, through the light-transmissive housing (a) a luminous flux of at least 1500 lumens +/?10% when energized with a 13.2 Volt test voltage, or of at least 1750 lumens +/?10% when energized with a 28 Volt test voltage, or (b) a luminous flux of at least 1350 lumens +/?10% when energized with a 13.

Abstract: In an embodiment a reflector optical system includes a reflector body having a rotational symmetry about a longitudinal axis and including a first reflector optic portion having a substantially concave shape and a second reflector optic portion extending along the longitudinal axis, the first reflector optic portion facing the second reflector optic portion, wherein the first reflector optic portion includes a plurality of first reflective surfaces and the second reflector optic portion includes a plurality of second reflective surfaces in spaced light-receiving relation to the plurality of first reflective surfaces.
