The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The present invention will be described in further detail with reference to the following drawings and specific examples, but the present invention is not limited thereto.
As shown in fig. 1 to 3, the annular light source capable of conveniently adjusting the light emitting angle provided by the present invention includes: the device comprises a first shell 1, a second shell 2, a reflecting lens 3, an adjusting mechanism 4 and a light source 5, wherein the reflecting lens 3, the adjusting mechanism 4 and the light source 5 are arranged in a cavity formed by the first shell 1 and the second shell 2, one end of the reflecting lens 2 is abutted against the adjusting mechanism 3, and the other end of the reflecting lens 2 is abutted against the first shell 1; wherein, the first casing 1 is movably connected with the second casing 2, and the adjusting mechanism 4 is used for adjusting the axial distance between the reflecting lens 3 and the light source 5. The problems that the annular light sources 5 are various in types and nonuniform in structure are solved; the problem that the PCB of the lamp panel needs to be redesigned due to different light-emitting angles is effectively solved; the annular light source capable of conveniently adjusting the light emitting angle can conveniently adjust the light emitting angle according to the requirement of actual light efficiency in the test process, when different objects are tested, parts do not need to be taken down and replaced, the adjusted camera lens does not need to be moved, the test can be directly and quickly carried out, the test efficiency is improved, and the requirement of industrial quick detection is met.
Preferably, the reflecting surface of the reflecting lens 3 is an arc surface.

The adjusting process of the annular light source capable of conveniently adjusting the light emitting angle utilizes the light reflection principle and the light reflected by the reflecting lens 3 with different radians to have different angles, the first shell 1 and the second shell 2 are screwed and connected through threads, and the position of the reflecting lens 3 is adjusted to realize the adjusting effect on the light emitting angle; the position of the light source 5 is always kept unchanged, and with the change of the reflecting arc surface of the reflecting lens 3, the reflecting angle of the light beam emitted by the light source 5 at the same position is changed, as shown in fig. 3, the solid line is a reflecting path diagram of the reflecting lens 3 at the first position to the light beam, the dotted line is a reflecting path diagram of the reflecting lens 3 at the second position to the light beam, the more the first shell 1 is screwed, the faster the position of the reflecting lens 3 descends, the larger the change of the light emitting angle is, and once the proper position is adjusted, the first shell 1 stops rotating; at this time, the adjusting mechanism 4 is compressed and deformed, and the axial force generated by the adjusting mechanism enables the thread structure to generate a self-locking effect, so that the shell 1 keeps the current position, and the reflecting lens is attached to the No. 1 shell. When the housing 1 needs to be adjusted upwards, the first housing 1 is released anticlockwise, and the reflection lens 3 can gradually move upwards along with the anticlockwise rotation of the first housing 1 under the action of the force of the adjusting mechanism 4 until the uncompressed initial state of the adjusting mechanism is restored. In the process of continuously adjusting the position of the first shell 1, the aim of continuously adjusting the light-emitting angle can be achieved, and therefore the best test effect of the tested object can be found.
