An internal-reflective telecentric lens system includes a first lens assembly, a reflector, and a second lens assembly. The first lens assembly includes a first lens. The second lens assembly includes a second lens, a third lens, and a fourth lens, that are disposed in sequence along a light path. The first lens assembly is configured to receive and output one or more light beams towards the reflector. The reflector is configured to reflect the light beams towards the second lens assembly. The second lens assembly is configured to receive and converge the light beams reflected by the reflector at a diaphragm between the second lens and the third lens, and transmit the light beams past the diaphragm through the third and the fourth lenses for imaging.

Internal-reflective telecentric lens system

A luminaire and an illumination system are disclosed. In an embodiment a luminaire includes at least one light-emitting semiconductor chip having a main emission side and a reflector having a reflection side facing the main emission side, the reflection side being a freeform different from a circle, an ellipse, a parabola or a hyperbola when seen in cross-section, wherein a base line of the reflector runs through the main emission side and a local height of the reflection side is measured against the base line, wherein a local focal length of the reflection side is increased along the local height, concerning ray bundles coming in parallel with the base line from an exterior of the luminaire during operation, and wherein local heights do not have a common focal point.
