Abstract:
1. An optoelectronic apparatus, comprising: at least one light-emitting, optoelectronic, first functional element, said first functional element, during operation, activated by an electrical signal, emitting light, at least at times, and said first functional element showing an imaginary principal ray axis representing a direction of maximum intensity of light emitted by said first functional element during operation; at least one light-sensitive, optoelectronic, second functional element, said second functional element, during operation, activated by light falling thereon, delivering, at least at times, an electrical signal, and said second functional element showing an imaginary principal-axis representing a direction of maximum sensitivity of said second functional element to light incoming during operation; as well as at least a third functional element composed, at least partially, of transmissive material, said third functional element, during operation, conveying light coupled thereinto, and said third functional element including at least one, essentially planar, boundary surface, which deflects light conveyed in the apparatus, said at least one, essentially planar, light deflecting, boundary surface of the third functional element showing a surface normal, which is inclined at least with respect to the principal axis at least of one of said first and second optoelectronic, functional elements, wherein: the third functional element includes a first boundary surface facing the first functional element, as well as a second boundary surface facing the second functional element, said first boundary surface coupling light, emitted during operation by the first functional element, into the third functional element, and said second boundary surface coupling light, conveyed within the third functional element during operation, out in the direction of the second functional element; at least one of said first and second light coupling, boundary surfaces of the third functional element is formed essentially planarly and shows a surface normal, which is inclined at least with respect to the principal ray axis at least of one of the two optoelectronic, functional elements; each of said first and second light-coupling, boundary surfaces of the third functional element is formed planarly; each of the two light-coupling, boundary surfaces of the third functional element shows a surface normal, which is inclined relative to the principal ray axis of its corresponding optoelectronic, functional element; the first and second light-coupling, boundary surfaces of the third functional element are so oriented with respect to one another and so arranged at the third functional element that a smallest angle of intersection included between their surface normals extended out over the third functional element amounts to less than 120°; and the first and second light-coupling, boundary surfaces of the third functional element are so oriented with respect to one another and so arranged at the third functional element that a smallest angle of intersection included between their surface normals extended out over the third functional element amounts to more than 10°.
