specific Embodiment approach 1

[0025] Specific implementation mode one: combine figure 1 Describe this embodiment, the linear laser light source described in this embodiment includes a laser 1, a collimator lens 2 and a conical reflector 3, and the laser 1, collimator lens 2 and conical reflector 3 are arranged at intervals in sequence, and the laser 1 The emitted laser light is collimated by the collimating lens 2 and converted into parallel light, which is then reflected by the conical mirror 3 and converted into 360° laser light;

[0026] In this specific embodiment, when in use, the light source is mainly composed of a fiber-coupled laser light source, a collimating lens 2 and a conical reflector 3. The light is emitted by the light source and becomes parallel light after being collimated by the collimating lens 2, and the parallel light The reflection of the mirror becomes a 360-degree line laser. By changing the shape of the conical mirror 3, the laser angle can be adjusted from 0 to 360 degrees. Thi...

specific Embodiment approach 2

[0027] Specific implementation mode two: combination figure 1 Describe this embodiment. This embodiment is a further limitation on the linear laser light source described in Embodiment 1. In the linear laser light source described in this embodiment, the conical reflector 3 is a conical reflector, and the The apex of the conical reflector 3 is arranged near the side of the collimator lens 2, the axis of the laser 1, the axis of the collimator lens 2 and the axis of the conical reflector are on the same straight line, the conical reflector The cross-section is an isosceles right triangle, and the apex angle of the conical reflector close to the collimating lens 2 is 90°.

specific Embodiment approach 3

[0028] Specific implementation mode three: combination figure 2 Describe this embodiment. This embodiment is a further limitation on the linear laser light source described in the second specific embodiment. The linear laser light source described in this embodiment also includes a plane reflector 4, along the light Propagation direction, the plane reflector 4 is arranged between the collimator lens 2 and the conical reflector 3, the parallel light is first reflected by the plane reflector 4, and then passes through the cone after changing direction Shaped mirror 3 reflection, converted into 360 ° of laser light.

[0029] In this embodiment, the arrangement position and structure of the linear laser light source are more flexible by arranging the plane reflector 4 to adjust the direction of the laser light.

Abstract

The invention provides a linear laser light source and shooting equipment, and relate to the technical field of light source compensation. The objective of the invention is to solve the problems of poor illumination uniformity, poor and unclear shooting effect, large equipment size and difficult maintenance caused by the splicing mode of multiple large-angle cameras and multiple light sources in the prior art. The laser device, the collimating lens and the conical reflector are sequentially arranged at intervals, laser emitted by the laser device is collimated by the collimating lens and converted into parallel light, and the parallel light is reflected by the conical reflector and converted into 360-degree laser. The invention is applicable to the technical field of light source compensation.

Description

technical field [0001] The invention relates to the technical field of light source compensation, in particular to a linear laser light source and a photographing device. Background technique [0002] A wide-angle camera is a camera with a lens with a wider angle of view. In the same location, the viewfinder range of the wide-angle lens camera is larger than that of the standard lens camera, and the viewfinder range can be wider than our naked eyes. In this way, when facing a large subject and there are not enough points behind, the wide-angle camera can obtain a relatively complete shot, thereby obtaining relatively complete image information of the subject. [0003] At present, when shooting with a wide-angle camera, the matching compensation light source mostly adopts the method of splicing multiple light sources. However, the method of splicing multiple light sources will lead to problems such as poor uniformity of illumination, poor shooting effect, and unclearness. M...
