Embodiment Construction
[0091] in figure 1 The optoelectronic device 1 according to the first embodiment shown in has an optical active region 100. The optically active region 100 includes a semiconductor chip 2 and a beam shaping element 3, which is a lens here.
[0092] The semiconductor chip 2 has a layer sequence which contains a semiconductor material. For example, the semiconductor material is a III-V compound semiconductor material, such as AlInGaN. This layer sequence includes an active layer 20 which is provided for generating electromagnetic radiation, which is indicated by arrow 4.
[0093] The layer sequence comprising III-V compound semiconductor material is in the context of this article an active, ie electroluminescent epitaxial layer sequence, wherein at least one layer (for example active layer 20) comprises III / V compound semiconductor material, such as nitrogen Compound-III-compound semiconductor material, such as Al n Ga m In 1-n-m N, where 0≤n≤1, 0≤m≤1 and n+m≤1. Here, the materi...

The invention relates to a lighting device having a luminous surface and a plurality of optoelectronic components each having an optically active area, wherein the optically active area comprises at least one semiconductor chip designed to generate Electromagnetic radiation; a beam-shaping element through which at least a part of the electromagnetic radiation emitted by a semiconductor chip in operation exits, and which has an optical axis; and the optically active region has a direction perpendicular to the optical axis Quadrant symmetry of the coordinate system, the optical axes of the optoelectronic devices are arranged parallel to each other, the light-emitting surface is arranged behind the optoelectronic device in the direction of the optical axis, and the surface illuminated by the adjacent device in a plane perpendicular to the optical axis Intersecting at least partially, the optoelectronic components have the same emission characteristics and are arranged at the same distance from one another, so that the illuminance induced by the components on the luminous area superimposes to a constant illuminance in all directions.
Description
[0001] The present application is a divisional application for an invention patent application with an application date of June 28, 2007, an application number of "200780024220.6", and an invention title of "optoelectronic devices and lighting equipment". [0002] This application claims the priority of German patent applications 102006030253.2 and 102006050880.7, the disclosures of which are incorporated herein by reference. Technical field [0003] The invention relates to an optoelectronic device and a lighting equipment. Background technique [0004] Optoelectronic devices are often used to illuminate rectangular surfaces. For example, backlighting devices for flat screens are disclosed, and these backlighting devices have a plurality of optoelectronic devices. However, optoelectronic devices generally have rotationally symmetric radiation characteristics. With this kind of optoelectronic device, it is impossible to achieve uniform illumination of a rectangular surface, becaus...
