Abstract

The invention discloses a relay lens and a lighting system. The relay lens comprises a first part and a second part. The first incident plane of the first part is a plane perpendicular to the light path, and a first emitting face of the first part is a convex ball face. The second part is located at the center position of the first part, a second incident plane of the second part is a plane perpendicular to the light path, and the curvature of a second emitting face of the second part is smaller than the curvature of the first emitting face. Due to the fact that no strict requirements for whether the lighting light rays at the center position are collimated into parallel light rays or not exist, when the curvature of the second emitting face of the second part located at the center position of the first part is smaller than the curvature of the first emitting face of the first part, the rise of the relay lens can be reduced on the premise that the lighting effect is not influenced, andaccordingly, the total length of the relay lens is reduced.

Description

technical field [0001] The invention relates to the lighting field, in particular to a relay lens and a lighting system. Background technique [0002] The miniaturization of optical path structure is the development trend of optical instruments, especially in the field of lighting of wearable devices, the demand for miniaturized optical instruments is even stronger. However, miniaturized optical paths generally require novel optical components, such as aspheric surfaces, Fresnel lenses, and binary optical lenses. Compared with spherical lens elements, the processing technology of these lens elements is very difficult, which is reflected in the fact that the required processing machine tools and testing equipment are very complicated, which will inevitably increase the cost and processing cycle of such elements. [0003] figure 1 is a schematic diagram of a relay lens in a lighting system of a prior art wearable device. The relay lens is a spherical lens, the direction A i...
