  • Publication number: 20140246690
    Abstract: An optoelectronic semiconductor component includes one or more light-emitting diode chips. The light-emitting diode chip has a main radiation side. A diaphragm is arranged downstream of the main radiation side along a main radiation direction of the light-emitting diode chip. The diaphragm is mounted on or in a component housing. The main radiation side has a mean edge length of at least 50 ?m. The diaphragm can be switched from light-impervious to light-pervious. The diaphragm comprises precisely one opening region for radiation transmission. The semiconductor component can be used as a flashlight for a mobile image recording device.

  • Publication number: 20140070246
    Abstract: The invention relates to a light-emitting semiconductor component, comprising—a first semiconductor body (1), which comprises an active zone (11) in which during the operation of the light-emitting semiconductor component electromagnetic radiation is generated, at least some of which leaves the first semiconductor body (1) through a radiation exit surface (1a), and—a second semiconductor body (2), which is suitable for converting the electromagnetic radiation into converted electromagnetic radiation having a shorter wavelength, wherein—the first semiconductor body (1) and the second semiconductor body (2) are produced separately from each other,—the second semiconductor body (2) is electrically inactive, and—the second semiconductor body (2) is in direct contact with the radiation exit surface (1a) and is attached there to the first semiconductor body (1) without connecting means.

  • Publication number: 20140061667
    Abstract: An optoelectronic semiconductor chip including a semiconductor body of semiconductor material, an outcoupling face arranged downstream of the semiconductor body in an emission direction and a mirror layer, wherein the semiconductor body includes an active layer that generates radiation, the mirror layer is arranged on the side of the semiconductor body remote from the outcoupling face, and a gap between the active layer and the mirror layer is set such that radiation emitted by the active layer towards the outcoupling face interferes with radiation reflected at the mirror layer such that the semiconductor chip features an emitted radiation pattern with a selected direction in the forward direction.

  • Publication number: 20130039617
    Abstract: An optoelectronic component (1) comprises a carrier (2) and at least one semiconductor chip (3). The semiconductor chip (3) is arranged on the carrier (2) and designed for emitting a primary radiation (6). The semiconductor chip (3) is at least partly enclosed by an at least partly transparent medium (7) having a height (8) above the carrier (2) and a width (9) along the carrier (2). Particles (10, 11) are introduced into the medium (7) and interact with the primary radiation (6). The medium (7) has a ratio of the height (8) to the width (9) of greater than 1.

  • Publication number: 20070091444
    Abstract: The invention relates to a total internal reflection micro lens array for a wide-angle lighting system. The micro lens array includes a plurality of Fresnel lens structures formed on a same optical incidence surface. Each of the Fresnel lens structure comprises a plurality of grooves, each having a reflecting surface and a refractive surface. Incoming radiation incident through the incidence surface of the lens structure is internally totally reflected by the reflecting surface, refracted by the refractive surface and exits the lens structure.
