An optoelectronic lighting device includes a black housing including a cavity, wherein the cavity includes a base, a semiconductor component is arranged on the base of the cavity with an underside of a main body facing the base, and the cavity is filled with a reflective material from the base up to a predetermined height, which is smaller than a height of a top side of the main body relative to the base of the cavity such that electromagnetic radiation emerging from the main body through side faces may be reflected by the reflective material back in the direction of the side faces to couple reflected electromagnetic radiation into the main body such that at least part of the electromagnetic radiation coupled in may emerge again from the main body through the top side of the main body.

An optoelectronic assembly includes at least one first component that emits first electromagnetic radiation and at least one first photosensitive component that controls the first component. The first photosensitive component connects in parallel to the first component and has a first radiation-sensitive region in a beam path of the first electromagnetic radiation.

An optoelectronic component includes a carrier on which at least one first light-emitting semiconductor chip and one first light-absorbing semiconductor chip connected antiparallel to the at least one first light-emitting semiconductor chip, at least one second light-emitting semiconductor chip and one second light-absorbing semiconductor chip connected antiparallel to the at least one second light-emitting semiconductor chip, wherein the semiconductor chips are arranged on the carrier such that light from each light-emitting semiconductor chip falls on at least one of the light-absorbing semiconductor chips not connected to the respective light-emitting semiconductor chip, and the light-absorbing semiconductor chips are formed as protection diodes.

Method for defining the color group of an LED which emits mixed-color, in particular white, light. The CIE color space is divided by means of a network with two sets of intersecting network lines, one set being provided by a set of Judd straight lines and the other set by the line for the color loci of a Planckian radiator and also the associated lines of constant threshold value deviation, so that the network has a plurality of network cells bounded by network lines. The color locus of the LED is determined, and the network cell is determined in which the color locus of the LED is located. The LED is assigned to the color group of the network cell.

An optical bidirectional transceiver module includes a module body having an opening, an inner hollow space and a fiber pin pushed through the opening into the inner hollow space. The fiber pin has a centric bored hole in which a light-conducting fiber is guided. A wavelength-selective filter or a beam splitter is located at a beveled end surface of the fiber pin. Radiation from an externally coupled light waveguide is emitted through the light-conducting fiber and reflected at the filter to a first optoelectronic component (transmitter). Received light radiation passes through the filter and impinges on a second optoelectronic component (receiver).

An optical device includes a surface-mountable optical component with a base member having a recess filled with a transparent filler and a VCSEL element arranged in the recess. A receptacle is attached to the surface-mountable optical component. The receptacle is for receiving an optical fiber to optically connect the VCSEL element to the optical fiber. Accordingly, an inexpensive way of coupling a VCSEL element with an optical fiber is provided. In particular, the surface-mountable component can be produced using a high volume production so that the overall costs of the optical device are reduced, even if the receptacle is produced in lower numbers due to varying requirements in the way that the VCSEL will be coupled to an optical fiber.

Optical device

An optoelectronic module is disclosed, which can be connected optically and electrically in a simply way. The optoeletronic module consists of a SMD-housing ( ) for the electrical connection and a connector ( ), on which a MT-plug is fitted, for the optical connection. The SMD-housing is assigned to the MT-plug. It includes a plug connector ( ), which contains the optical/electrical interface and is positively fixed in the housing.

A configuration for triggering a restraining device has firing elements that are optically fired by an associated triggering device. In addition, an optical check signal can be transmitted to the firing element by the triggering device. An evaluation circuit evaluates light signals that have been transmitted to the triggering device. As a function of an evaluated, received light signal, a disable signal, by which emission of a firing signal is prevented, is generated by the evaluation circuit.

A laser component with a laser array and an optical device for shaping the laser beams emitted by the laser array. The optical device comprises a deflection mirror element following the laser array in the beam direction that simultaneously deflects the individual laser beams of the emitted laser array beam from the radiation direction with respectively the same rotational sense parallel to the common plane and perpendicular thereto. The deflection mirror element is composed of a step-shaped light waveguide stack.
