Description

A multi-light street lamp structure of an image measuring instrument

technical field

The utility model relates to the field of image measuring instruments, in particular to a bottom light spotlight structure of an image measuring instrument.

Background technique

The traditional image measuring instrument needs to add incident light to achieve the auxiliary purpose when measuring. However, due to factors such as the brightness and light wave frequency of optical image measurement, the structure used in the measurement is generally very complicated. , The adjustment of the incident light, especially the replacement of the color of the background light and the superposition of the two are also relatively complicated and troublesome, so it is difficult to meet the measurement requirements, or it needs to be realized with expensive measurement equipment.

Utility model content

The utility model aims at the shortcomings in the above background, and provides a light gathering structure of an image measuring instrument, which can conveniently obtain different color lights by changing the color of the bottom light.

Its realized technical scheme is as follows:

A multi-light street lamp structure for an image measuring instrument, comprising a bottom light source, a light source fixture, a semi-transparent and semi-reflective lens, and a side incident light source. Perpendicular to the direction of incidence of side incident light sources.

Further, the semi-transparent mirror and the side incident light source form an included angle of 45°, and the reflected light of the side incident light source is in the same direction as the incident light of the bottom surface light source.

Further, the bottom surface light source is an astigmatism light source, and is a switchable monochromatic light source. The side incident light source is diffuse light or parallel light source, and is a convertible monochromatic light source.

The beneficial effects of the utility model are: a semi-reflective and semi-transmissive mirror is provided with an angle of 45° with the bottom surface of the fixture. Due to its semi-reflective and semi-transmissive properties, the incident light source on the side is reflected and the light source on the bottom surface is transmitted. One incident light source has a 90-degree incident angle, and the two light sources can be gathered in the same direction to achieve the effect of concentrating light. In addition, different color lights can be obtained by changing the color of the bottom light and side incident light to meet the needs of measurement.
