Description

Technical Field

[0001] The utility model relates to the technical field of light sources, in particular to a light source and a detection device. Background Art

[0002] The current light source includes a circuit board and lamp beads installed on the circuit board. The light emitted by the lamp beads is parallelly emitted after passing through a condenser lens group, so as to illuminate the workpiece. When it is necessary to change the lighting effect of the light source, generally, the specifications of the lamp beads installed on the circuit board are adjusted, such as replacing lamp beads of different colors. However, this requires completely disassembling the lamp beads, and the circuit board is easily damaged during the process of replacing the lamp beads.

[0003] In view of this, it is necessary to design a light source and a detection device that can more simply adjust the light output effect.

[0004] The above information is given as background information only to assist in understanding the present disclosure, and it is not determined or admitted whether any of the above content can be used as the prior art relative to the present disclosure. Summary of the Utility Model
