Description

Technical Field

[0001] The utility model relates to the technical field of laser intensity regulation, and more specifically to a laser irradiation intensity regulation device and a laser dazzler. Background Art

[0002] The output power of existing laser lighting or dazzling devices is constant. When adjusting the beam divergence angle or changing the distance between the light source and the irradiated target, the laser power cannot be automatically adjusted. When the target is far away or the beam divergence angle is too large, the brightness is easily too low and the lighting or dazzling function cannot be achieved; when the target is close or the beam divergence angle is too small, the brightness is too high, causing irreversible damage to the human eye. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem that the existing laser device cannot adjust the laser irradiation intensity according to the distance of the target, and to provide a laser irradiation intensity adjustment device, which can adjust the laser irradiation intensity, so as to ensure sufficient irradiation intensity within the effective working range of the laser device without causing unexpected damage to the target and personnel.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A laser irradiation intensity adjustment device, comprising

[0006] A fixing mechanism, used for installing and fixing various components;

[0007] A laser emission module, used for emitting laser, wherein the laser emission module is fixedly mounted on the fixing mechanism;

[0008] A beam divergence angle adjustment mechanism is used to adjust the size of the beam divergence angle of the laser emission, and the beam divergence angle adjustment mechanism is movably mounted on the fixing mechanism and is located at the front end of the laser emission module;

[0009] A first detection mechanism, used to detect the change of the beam divergence angle, the first detection mechanism comprising a fixed part and a movable part, the fixed part is installed on the fixed mechanism, the movable part is connected to the beam divergence angle adjustment mechanism, and the fixed part and the movable part are inductively connected;

[0010] A second detection mechanism, used for detecting a change in the distance between the laser emission module and the irradiation target, wherein the second detection mechanism is installed on the fixing mechanism (1);

[0011] The controller is used to control the laser irradiation intensity; the laser emission module, the fixed part of the first detection mechanism (4), the movable part of the first detection mechanism (4), and the second detection mechanism are all connected to the controller for communication.

[0012] The laser emission module of the utility model is used to emit laser, and the beam divergence angle adjustment mechanism can be used to adjust the size of the beam divergence angle of the laser emission, thereby changing the size of the light spot and realizing the precision adjustment of the laser focus. When the beam divergence angle is large, if the laser irradiation intensity is constant, it is easy to cause the brightness to be too low, and the lighting or dazzling function cannot be realized; when the beam divergence angle is too small, it is easy to cause the brightness to be too high, causing irreversible damage to the human eye. The first detection mechanism is used to sense the position change through the movable part and the fixed part, and then detect the change of the beam divergence angle, so that the laser irradiation intensity is adaptively changed through the controller to overcome the influence of the beam divergence angle on the brightness, so that the laser device always maintains a more appropriate brightness. The second detection mechanism is used to detect the change in the distance between the laser emission module and the irradiation target. Similar to the influence of the beam divergence angle on the laser brightness, when the target distance is far, it is also easy to cause the brightness to be too low; when the target distance is close, it will also cause the brightness to be too high. Therefore, the utility model simultaneously detects changes in beam divergence angle and target distance. When one of them changes, the controller can be used to regulate the laser emission module, control the power of the laser emission, and thus change the laser irradiation intensity, so that it is always in a better state.

[0013] Furthermore, the beam divergence angle adjustment mechanism includes a lens assembly, a transmission assembly, and a drive assembly. The lens assembly is located at the front end of the laser emission module and is connected to the transmission assembly. The transmission assembly is connected to the output end of the drive assembly. The first detection mechanism is connected to the transmission assembly. The lens assembly, the transmission assembly, and the drive assembly are all movably connected to the fixing mechanism. The lens assembly is used to adjust the size of the beam divergence angle, specifically by changing the position of the lens assembly relative to the fixing mechanism, thereby changing the size of the beam divergence angle. The drive assembly is used to drive the transmission assembly to move, thereby causing the lens assembly to follow the movement, thereby achieving a change in the position of the lens assembly relative to the fixing mechanism.

[0014] Furthermore, the transmission assembly includes a gear and a rack that mesh with each other, the rack is fixedly connected to the lens assembly, the gear is connected to the driving assembly, and the gear and the rack are both movably connected to the fixing mechanism. The gear and the rack are commonly used transmission mechanisms, which can achieve high-precision position adjustment, and the rotation of the gear drives the rack to move so that the lens assembly moves accordingly.

[0015] Furthermore, the driving component is a knob, and the output shaft end of the gear is engaged with the knob. Turning the knob drives the output shaft of the gear to rotate, and the gear rotates accordingly, the rack meshes with the gear, and the rack moves, thereby driving the lens component to move relatively, so that the beam divergence angle of the laser changes. Within the scope of knowledge of those skilled in the art, the driving component can also be other structures, such as a motor, which can be used to achieve the driving function.

[0016] Furthermore, the lens assembly includes a lens and a lens seat, wherein the lens is mounted on the lens seat, and the lens seat is mounted on the rack and movably connected to the fixing mechanism. By utilizing the position change of the lens relative to the fixing mechanism, the position change of the lens and the laser emission module is achieved, thereby changing the beam divergence angle of the laser, and the lens seat is used to be mounted on the fixed lens, and the lens seat is fixedly connected to the rack, so that when the rack moves, the lens seat can drive the lens to move relative to the fixing mechanism.

[0017] Furthermore, it also includes a follower pin, through which the lens seat is connected to the rack. One end of the follower pin is plugged into the lens seat, and the other end is plugged into the rack, so that the rack can move and the lens seat can move at the same time.

[0018] Furthermore, the transmission assembly includes a lead screw and a nut, the lens assembly is mounted on the nut, the lead screw is connected to the drive assembly, and the lead screw and the nut form a lead screw nut transmission pair. The drive assembly drives the lead screw to rotate, which is converted into a linear motion of the nut through the lead screw nut transmission pair, thereby driving the lens assembly to move relative to the laser emission module, thereby changing the laser beam divergence angle. Within the scope of cognition of those skilled in the art, the transmission assembly can also be other structures.

[0019] Furthermore, the movable part of the first detection mechanism is a follow-up sensor, and the fixed part of the first detection mechanism is a fixed sensor. Specifically, when the transmission assembly is a gear rack structure, the follow-up sensor is installed at the end of the rack; when the transmission assembly is a screw nut structure, the follow-up sensor is installed on the nut; the follow-up sensor can move with the rack or nut, and the fixed sensor is fixedly installed at a certain position of the fixed mechanism, and the position change between the fixed sensor and the follow-up sensor is used to sense the distance change of the lens assembly position, so that the displacement of the rack or nut relative to the initial position can be calculated, and the change of the beam divergence angle can be further clarified, and then the data is fed back to the controller to adjust the power of the laser emission module so that the irradiation intensity of the laser emitted by it is adaptively changed, and finally the laser device always has the optimal irradiation intensity, which can not only meet the functional needs, but also avoid damage to the eyes.

[0020] Furthermore, the second detection mechanism is a distance measuring module. The distance measuring module can detect the distance between the fixing mechanism and the irradiation target, and then measure the distance between the adjusting device and the irradiation target; when the distance measuring module detects that the distance between the adjusting device and the irradiation target becomes larger, the system increases the power of the laser emission in the laser emission module through the controller according to the distance parameter, so that the laser irradiation intensity reaches the optimal value; when the rangefinder detects that the distance between the adjusting device and the irradiation target becomes smaller, the system reduces the power of the laser emission in the laser emission module through the controller according to the distance parameter, so that the laser irradiation intensity reaches the optimal value.

[0021] Furthermore, the laser emission module includes a laser diode and a diode fixing member, wherein the laser diode is fixedly mounted on the diode fixing member, and the diode fixing member is mounted on a fixing mechanism. The diode fixing member is used to fix the laser diode, and the laser diode is used to emit laser light; the controller adjusts the power of the laser diode to achieve the purpose of controlling the laser irradiation intensity.

[0022] Furthermore, the fixing mechanism is a sleeve, the laser emission module is installed in the sleeve, and the beam divergence angle adjustment mechanism is partially installed in the sleeve and partially installed outside the sleeve. Specifically, the lens assembly in the beam divergence angle adjustment mechanism is partially installed in the sleeve, and the transmission assembly and the drive assembly are partially installed outside the sleeve; the mechanism emitted by the laser emission module passes through the lens module and is emitted from the end of the sleeve, and the end of the sleeve away from the laser emission module is the light-emitting port, and the distance measurement module can obtain the detection parameters by detecting the distance between the light-emitting port and the irradiated target.

[0023] The utility model also provides a laser dazzler, comprising the laser irradiation intensity adjustment device as described above. The laser dazzler is the laser device as described above, which is used to emit laser and can realize clear lighting or dazzling function.

[0024] The beneficial effects of the utility model are:

[0025] (1) By turning the knob, the gear is driven to rotate and then the rack is driven to move, and the lens is moved accordingly to change the size of the light spot. At the same time, the follow-up sensor is also moved accordingly. The fixed sensor can sense the change in the position of the knob, and the power of the laser diode in the laser emission module is controlled by the controller so that the laser irradiation intensity is consistent before and after adjustment, and the laser irradiation intensity will not decrease or increase due to the change in the laser beam divergence angle, so that the laser irradiation intensity is always kept at the optimal level. Compared with the laser lighting or dazzling device with constant output power in the prior art, the utility model can automatically adjust the laser power when adjusting the beam divergence angle.

[0026] (2) When the target distance changes, the distance measurement module is used to sense the change in distance, and the controller is used to control the laser irradiation intensity to be consistent before and after the target distance changes, so that the laser irradiation intensity will not decrease or increase due to the change in the target distance, and the laser irradiation intensity is always kept optimal. Compared with the laser lighting or dazzling device with constant output power in the prior art, the utility model can automatically adjust the laser power when the distance between the light source and the irradiated target changes.

[0038] The laser emission module 2 of the utility model is used to emit laser, and the beam divergence angle adjustment mechanism 3 can be used to adjust the size of the beam divergence angle of the laser emission, thereby changing the size of the light spot and realizing the precision adjustment of the laser focus. When the beam divergence angle is large, if the laser irradiation intensity is constant, it is easy to cause the brightness to be too low, and the lighting or dazzling function cannot be realized; when the beam divergence angle is too small, it is easy to cause the brightness to be too high, causing irreversible damage to the human eye. The first detection mechanism 4 is used to sense the position change through the movable part and the fixed part, and then detect the change of the beam divergence angle, so that the laser irradiation intensity is adaptively changed through the controller to overcome the influence of the beam divergence angle on the brightness, so that the laser device always maintains a more appropriate brightness. The second detection mechanism is used to detect the change in the distance between the laser emission module 2 and the irradiation target. Similar to the influence of the beam divergence angle on the laser brightness, when the target distance is far, it is also easy to cause the brightness to be too low; when the target distance is close, it will also cause the brightness to be too high. Therefore, the utility model simultaneously detects changes in beam divergence angle and target distance. When one of them changes, the controller can be used to regulate the laser emission module 2 to control the power of the laser emission and thus change the laser irradiation intensity, so that it is always in a better state.

The driving assembly is used to drive the transmission assembly to move, and then the lens assembly follows the movement, so that the position of the lens assembly relative to the fixing mechanism 1 changes.

The gear 33 and the rack 34 are commonly used transmission mechanisms, which can achieve high-precision position adjustment, and the rotation of the gear 33 drives the rack 34 to move so that the lens assembly moves accordingly.

[0042] As an improved solution of this embodiment, the driving component is a knob 35, and the output shaft end of the gear 33 is engaged with the knob 35. The knob 35 is turned to drive the output shaft of the gear 33 to rotate, and the gear 33 rotates accordingly, and the rack 34 meshes with the gear 33, and the rack 34 moves, thereby driving the lens component to move relatively, so that the beam divergence angle of the laser changes.

The position of the lens 31 relative to the fixing mechanism 1 is changed to achieve the position change of the lens 31 and the laser emission module 2, so that the beam divergence angle of the laser can be changed. The lens seat 32 is used to be installed on the fixed lens 31. The lens seat 32 is fixedly connected to the rack 34, so that when the rack 34 moves, the lens seat 32 can drive the lens 31 to move relative to the fixing mechanism 1.

[0044] Furthermore, a follower pin 36 is included, and the lens seat 32 is connected to the rack 34 through the follower pin 36. One end of the follower pin 36 is plugged into the lens seat 32, and the other end is plugged into the rack 34, so that the rack 34 can move while the lens seat 32 can move.
