Description

Technical Field

[0001] The utility model relates to the technical field of BRDF light sources, in particular to a BRDF light source position adjustment mechanism. Background Art

[0002] BRDF is the abbreviation of bidirectional reflectance distribution function, which describes the distribution of light when it is emitted from or reflected by a surface. In optics, BRDF is used to describe the reflection properties of light on the surface of an object. The BRDF light source can facilitate the propagation and reflection of light between different object surfaces. When testing the lighting effect of the material surface, it is necessary to use the BRDF light source position adjustment mechanism, which affects the surface lighting effect of the object.

[0003] When testing the lighting effect on the surface of a material, a BRDF light source position adjustment mechanism is required. The "light source position adjustment mechanism" disclosed in the announcement number "CN207842177U" has solved the various disadvantages of irradiating in one direction, which will affect the image forming effect when the surface paper is in a position where the light source component cannot illuminate or the brightness is too low.

[0004] However, there are still many defects in the actual use of BRDF light source equipment with similar structure. For example, in the existing technology, the operator is required to manually adjust the irradiation position of the light source, which increases the workload of the operator. The irradiation range of the light is easily limited by the operator's experience, which reduces the accuracy of the mobile device's irradiation light source. It is not convenient to adjust the device's irradiation position according to the operator's usage needs, and it is not convenient to promote the use of the device. Therefore, a BRDF light source position adjustment mechanism is proposed. Utility Model Content

[0026] The BRDF light source adjustment mechanism 2 includes a mounting base 201, a servo motor 202 is fixedly mounted on one side of the mounting base 201, a winding roller 203 is fixedly mounted on the output end of the servo motor 202, and an encoder 204 fixedly mounted on one side of the mounting base 201 and fixedly connected to one end of the winding roller 203, a transmission chain 205 is wound around the outer side of the winding roller 203, a movable base 206 is sleeved on the outer side of the transmission chain 205, and the top of the movable base 206 is fixedly connected to the bottom of the telescopic rod 3;

[0027] The light adjustment mechanism 5 includes a housing 501, a light board 502 is fixedly mounted on one side of the housing 501, a lampshade 503 is embedded in the front side of the housing 501, and a spring winding roller 207 is fixedly mounted on one side of the box 1, and the spring winding roller 207 is fixedly connected to one side of the movable seat 206 via a steel cable;

[0028] A constant speed motor 401 is fixedly mounted on one side of the fixing base 4, and the output end of the constant speed motor 401 is fixedly connected to one side of the housing 501. A connecting plate 6 is fixedly mounted on the outside of the telescopic rod 3, and a light sensing circuit board 601 is embedded in the connecting plate 6.

[0029] The servo motor 202 is powered on to drive the winding roller 203 to rotate, and the rotating winding roller 203 can reel the transmission chain 205, so that the transmission chain 205 moves, and the moving transmission chain 205 can drive the movable seat 206 to move its position. Then, the encoder 204 is powered on to monitor and calculate the number of rotations of the winding roller 203 in real time to obtain the retracted length of the transmission chain 205. Then, the moving position of the movable seat 206 can be obtained by calculating the retracted length of the transmission chain 205. The encoder 204 is used in conjunction with the servo motor 202 to improve the movement accuracy of the movable seat 206.

[0030] The high elastic force of the spring winding roller 207 can apply tension to the movable seat 206 through the steel cable, so that the movable seat 206 is limited, ensuring the stability of the installation position of the movable seat 206. The housing 501 can be driven to rotate by the constant speed motor 401, and the rotating housing 501 can drive the light board 502 to adjust the use angle, thereby increasing the flexibility of the device.
