Description

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 12, 2023, with application number 202311695657.X and invention name “A Multifunctional Dimming Lamp and Dimming Method”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the field of dimming technology, and in particular to a multifunctional dimming lamp and a dimming method. Background Art

[0003] Existing lamps refer to devices that can transmit, distribute and change the light distribution of light sources, including all parts required to fix and protect the light source in addition to the light source, as well as the wiring accessories necessary for connecting to the power supply. Most lamps are light-emitting devices such as flashlights;

[0004] A multi-purpose LED lamp disclosed in patent number CN208457596U is retrieved, comprising a bottom box, mounting tubes being installed at both ends of the bottom box, a mounting post being installed at the middle position of the bottom of the bottom box, and a mounting plate being installed at the bottom of the mounting post, a lamp holder being installed at the middle position inside the bottom box, an LED lighting lamp being installed on the top of the lamp holder, a first motor being installed at one end of the bottom end inside the bottom box, and a first rotating shaft being installed at the output end of the first motor, this utility model drives a concave mirror and different convex mirrors to rotate by a motor, thereby controlling the refraction of light, making the light converge and disperse, thereby adjusting the intensity of the light, and at the same time driving light-transmitting covers of different colors to rotate by a motor, thereby adjusting the color of the light, and not only the intensity and color of the light can be adjusted according to the needs of different atmospheres, but also the application range of the light is wider;

[0005] According to the above patent, when the LED lamp is in use, the convex mirror and the concave mirror are replaced to control the light diffusion and focusing. The conversion of the convex mirror and the concave mirror is controlled by the motor output, thereby changing the illumination condition of the LED lamp.

[0006] However, it is driven by a motor and cannot be applied to real flashlights. When replacing the focusing and astigmatism, the convex mirror and concave mirror need to be replaced by the motor and its electrical control components, and servo devices such as the adaptor motor need to be adapted. Not only does it require an electric power source for control, but it also increases the overall mass and has a high cost of use. In reality, a flashlight can change the lighting conditions by changing the distance between the convex mirror and the light source, but the convex mirror of this setting is mostly fixed, and it is difficult to switch between the convex mirror and the concave mirror.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] The present invention provides two technical solutions:

[0044] Example 1

[0045] See also Figure 1-16 A multifunctional dimming lamp includes a flashlight 1, a convex lens 6, and a concave lens 7. The front end of the flashlight 1 is provided with a lens switching component 2 for quickly changing the light. The lens switching component 2 is used to synchronously switch the convex lens 6 and the concave lens 7;

[0046] The mirror switching assembly 2 includes a clamping tube 201 sleeved on the outer surface of the flashlight 1, and a concave mirror shell 202 and a convex mirror shell 203 are provided on the outer surface of the clamping tube 201. The inner surfaces of the concave mirror shell 202 and the convex mirror shell 203 are both slidably provided with a push plate 204, and a center rod 205 is fixed in the middle of the push plate 204. An arc rod 206 is rotatably provided on the outer surface of one of the center rods 205, and an arc guide groove 207 is opened at one end of the arc rod 206. The outer surface of the other center rod 205 slides on the arc On the inner surface of the arc-shaped guide groove 207, two push rods 208 are fixed at one end of the arc-shaped rod 206, and the arc-shaped rod 206 better fits the surface of the clamping cylinder 201 to prevent the arc-shaped rod 206 from causing motion interference, and the push plate 204 can only slide parallel to the inside of the concave mirror shell 202 and the convex mirror shell 203, which is convenient for pushing the convex lens 6 and the concave lens 7. The extended moving range of the arc-shaped guide groove 207 prevents one of the center rods 205 from moving to the final position and causing motion interference.

[0047] In the embodiment of the present invention, a fixing block 209 is fixed on one end of the concave mirror shell 202 and the convex mirror shell 203 away from the clamping tube 201, and a fixing clamp spring 210 is fixed on one end of the two push plates 204 away from the clamping tube 201. The angle between the concave mirror shell 202 and the convex mirror shell 203 in the same vertical plane is 90°. By making the angle between the concave mirror shell 202 and the convex mirror shell 203 90°, when pushing the arc rod 206, the driving point of the arc rod 206 can be directly changed, so that both ends of the arc rod 206 are pressing points. When replacing the convex lens 6 and the concave lens 7, there is no need to perform lifting actions, and only a pressing action is required to replace the convex lens 6 and the concave lens 7. A protective ring is provided on the outside of the convex lens 6 and the concave lens 7 to prevent scratches on the mirror surface when replacing the convex lens 6 and the concave lens 7.

[0048] In the embodiment of the present invention, a reflective assembly 3 for automatic fill light is provided at the front end of the mirror body switching assembly 2. During the switching process between the convex lens 6 and the concave lens 7, the arc rod 206 is driven to drive the reflective assembly 3 to change its angle accordingly. The reflective assembly 3 includes multiple groups of fixed plates 306 fixedly arranged at one end of the clamping cylinder 201. A connecting plate 307 is rotatably provided between each group of fixed plates 306. A tapered rod 308 is fixedly provided at one end of the connecting plate 307 close to the concave mirror shell 202. A reflector 309 is fixed at one end of the connecting plate 307. The multiple reflectors 309 are arranged in a ring shape. When the convex lens 6 is used, the reflective mirror 309 is tilted inward. When there is astigmatism, the reflective mirror 309 is tilted to concentrate part of the light source and enhance the light source at the center of the astigmatism. When the concave lens 7 is used, the reflective mirror 309 is tilted outward to increase the area where the light is emitted during irradiation, thereby preventing a large contrast between the inside and outside of the light beam from causing a blind spot in the line of sight.

[0049] In the embodiment of the present invention, an annular groove 301 is provided on the outer surface of the clamping cylinder 201, and a rotating ring 302 is provided on the outer surface of the annular groove 301 through a threaded connection. A forward rotating conical block 304 is fixedly provided on the end of the rotating ring 302 close to the concave mirror shell 202, and a reverse rotating conical block 305 is fixedly provided on the end of the rotating ring 302 close to the convex mirror shell 203. A plurality of arc-shaped adjustment grooves 303 are provided on the inner surface of the rotating ring 302, and the number of conical rods 308 and the arc-shaped adjustment grooves 303 are equal. The conical rods 308 slide on the corresponding inner surfaces of the arc-shaped adjustment grooves 303 respectively. A secondary adjustment rod 311 is provided on the outer surface of the rotating ring 302. When the convex lens 6 and the concave lens 7 are replaced, the push rod 208 can be moved The rotating ring 302 is automatically rotated during the movement, and it has a high degree of automation and is easy to use. It can also be finely adjusted through the auxiliary adjustment rod 311. The rotating ring 302 can prevent itself from being self-locked when it does not need to rotate through the characteristics of the thread. When the push rod is pressed, the rotating ring is rotated by the forward rotating conical block and the reverse rotating conical block in the reflective assembly. The inclination angles of the forward rotating conical block and the reverse rotating conical block are set to be opposite, so that the reflector can be adaptively tilted when using different lenses. It has a high degree of automation, simplifies the use method, realizes multiple adjustments, and can also make more subtle adjustments to the inclination angle of the reflector through the auxiliary adjustment rod to achieve the best lighting effect.

[0050] In the embodiment of the present invention, the front end of the flashlight 1 is provided with a mirror cleaning assembly 4 for automatically cleaning the mirror surfaces of the convex lens 6 and the concave lens 7. The mirror cleaning assembly 4 includes a plurality of cleaning shells 401 fixedly arranged on the outer surfaces of the concave mirror shell 202 and the convex mirror shell 203. Two connecting blocks 402 are slidably provided on the inner surface of the cleaning shell 401. An inner groove 403 is provided at one end of the connecting block 402. A protruding block 404 is fixed at one end of the cleaning shell 401, and an inner concave block 405 is fixed at one end of the other connecting block 402. A cleaning shell 401 is provided at both ends of the concave mirror shell 202 and the convex mirror shell 203, and the cleaning shells 401 are arranged opposite to each other, which can fully clean the lens surface. The protruding block 404 and the concave block 405 close to the concave mirror shell 202 are inclined at opposite angles to the protruding block 404 and the concave block 405 close to the convex mirror shell 203, which is convenient for clamping the cleaning block 407 to fit the mirror surface of the convex lens 6 and the concave lens 7, and a reset spring is provided between the protruding block 404 and the concave block 405, which can be reset when the clamping cleaning block 407 is not working.

[0051] In the embodiment of the present invention, a plurality of snap-fit cleaning blocks 407 are slidingly provided on the inner surface of the cleaning shell 401, and an elastic plate 406 is fixedly provided on the inner surface of the cleaning shell 401. Two driving inserts 408 are fixedly provided at one end of the push plate 204 close to the clamping cylinder 201, and a conical opening 409 is opened at one end of the driving insert 408. The front end of the snap-fit cleaning block 407 close to the mirror surface is made of sponge, which cleans the mirror surface more thoroughly. The elastic plate 406 is made of a highly elastic silicone plate, which replaces the multiple springs on the rear side of the snap-fit cleaning block 407. Under the drive of the push plate, the mirror surface can be automatically cleaned when the lens moves when the push plate drives the mirror surface, effectively preventing the mirror surface from fogging. In addition, through the different inclination angles of the protruding blocks and the concave blocks, the snap-fit cleaning block can be better fitted to the mirror surface, thereby preventing the snap-fit cleaning block from being damaged due to the large force on its cleaning surface due to the characteristics of the mirror surface at different parts of the snap-fit cleaning block due to the overall setting.

[0052] Figure 1 and Figure 3 、 Figure 6 、 Figure 15-16 A second embodiment is shown, which mainly differs from the first embodiment in that a quick-release assembly 5 for quickly disassembling and assembling the lens switching assembly 2 is provided at the front end of the flashlight 1, and the quick-release assembly 5 includes a plurality of fixing plates 508 fixedly arranged on the outer surface of the clamping cylinder 201, and an unlocking plate 509 is rotatably arranged between the two fixing plates 508. A plurality of locking cavities 502 are provided on the inner surface of the clamping cylinder 201, and a baffle 501 is provided on the outer surface of the clamping cylinder 201. A sliding plate 503 is slidingly provided on the inner surface of the locking cavity 502, and a rectangular block 504 is fixed at one end of the sliding plate 503. The unlocking method is changed by the unlocking plate 509, so that the pull-to-unlock is changed to the push-to-unlock, which is convenient for operation.

[0053] In the embodiment of the present invention, a sliding column 505 and a compression spring 506 are fixedly provided at the other end of the sliding plate 503. The compression spring 506 is sleeved on the outside of the sliding column 505. The other end of the compression spring 506 is fixedly connected to one end of the locking cavity 502. The other ends of the multiple sliding columns 505 are fixedly connected to a connecting rod 507. The locking cavity 502 is locked by multiple rectangular blocks 504, and one end of the rectangular block 504 is conical, which is convenient for assembly. When the flashlight is not needed or dimmed, the clamping tube and other parts can be removed and stored separately through the quick-release assembly. When dimming is not needed, the operator can also reduce the force required to pick up the flashlight, making it convenient for use.

[0054] The embodiment of the present invention further discloses a dimming method using a multifunctional dimming lamp, which specifically includes the following steps:

[0055] Step 1: The flashlight 1 uses the lens switching assembly 2 to quickly replace the convex lens 6 and the concave lens 7, thereby changing the light emitted by the flashlight 1 during operation;

[0056] Step 2: The reflective component 3 enhances the light emitted by the flashlight 1 and adaptively changes the reflective effect of the light according to the different usage of the convex lens 6 and the concave lens 7;

[0057] Step 3: When replacing the convex lens 6 or the concave lens 7, the mirror cleaning assembly 4 cleans and demists the mirror surfaces at both ends of the convex lens 6 and the concave lens 7. During cleaning, the mirror cleaning assembly 4 can better fit the mirror surface of the convex lens 6 or the concave lens 7 by snapping on the cleaning block 407.

[0058] In the embodiment of the present invention, step 3: when the flashlight 1 is not in use, the mirror switching assembly 2, the reflective assembly 3, and the mirror cleaning assembly 4 are separated from the flashlight 1 through the quick-release assembly 5 and stored separately.

[0059] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0060] When in use, the operator turns on the flashlight 1, adjusts the lighting conditions according to the usage scenario, and presses the push rod 208 in the lens body switching assembly 2, thereby moving the arc rod 206, which in turn drives the center rod 205 to move toward the clamping cylinder 201, thereby causing the center rod 205 to drive the push plate 204 to move, and then the push plate 204 pushes the concave lens 7 to move downward. When the concave lens 7 moves downward, the arc rod 206 also drives the other end of the center rod 205 to move through the arc guide groove 207, thereby changing the convex lens 6 and the concave lens. When the convex lens 6 is moved to the convex mirror housing 203, the push plate 204 drives the fixing clamp spring 210 to move, so that the fixing clamp spring 210 is clamped between the fixing blocks 209, and the arc rod 206 is limited to prevent it from moving. When the concave lens 7 needs to be replaced, the convex lens 6 and the concave lens 7 can be replaced by pressing the other end of the arc rod 206 again.

[0061] When the arc rod 206 is pressed, the push rod 208 drives the forward rotating conical block 304 in the reflective assembly 3, thereby rotating the rotating ring 302. When the rotating ring 302 rotates, the reverse rotating conical block 305 rotates to the same plane as the other push rod 208. When the rotating ring 302 is driven, the multiple arc-shaped adjustment slots 303 are driven to rotate, thereby rotating the conical rod 308. Under the limitation of the connecting plate 307 and the fixed plate 306, the conical rod 308 can only swing around the center of the connecting plate 307. When the conical rod 308 swings, the reflector 309 is driven to swing outward through the connecting plate 307, and the concave lens 7 is rotated. When the convex lens 6 is in operation, the reflector 309 disperses the emitted light to increase the brightness of the outer side of the concentrated light beam and prevent a large blind spot. When the convex lens 6 is in operation, the arc rod 206 drives the push rod 208 to squeeze and rotate the reversing conical block 305, thereby reversing the rotating ring 302, so that the rotating ring 302 drives the reflector 309 to tilt in the opposite direction, thereby concentrating the light beam at the center of the illumination when the convex lens 6 is in operation, and increasing the central brightness when the light is astigmatized. When the reflector 309 needs to be adjusted twice, the auxiliary adjustment rod 311 is manually rotated to rotate the rotating ring 302 twice, thereby making more detailed adjustments to the illumination.

[0062] When the push plate 204 moves, the two driving inserts 408 in the mirror cleaning assembly 4 are driven to move, and the driving inserts 408 drive the tapered opening 409 to move, and the tapered opening 409 squeezes the inner groove 403, and the two connecting blocks 402 in the same cleaning shell 401 are moved closer to each other, and the two connecting blocks 402 respectively drive the protruding block 404 and the inner concave block 405 to move closer to each other, and then the multiple clamping cleaning blocks 407 are moved in different directions by the taper of the protruding block 404 and the inner concave block 405. The extending range is extended, thereby making the extending length of the clamping cleaning block 407 different, so that the multiple clamping cleaning blocks 407 can better fit the mirror surface of the convex lens 6 and the concave lens 7. The tapers of the protruding blocks 404 and the concave blocks 405 are at different positions and the tapers inside the cleaning shell 401 are opposite, thereby being able to better fit the surfaces of the convex lens 6 and the concave lens 7 according to the inclination angles of the protruding blocks 404 and the concave blocks 405. The elasticity of the elastic plate 406 allows the clamping cleaning blocks 407 to be reset when they are not needed.

[0063] When the clamping cylinder 201 needs to be separated from the flashlight 1, it is only necessary to press the unlocking plate 509 so that the unlocking plate 509 lifts the connecting rod 507, and then the connecting rod 507 drives the sliding column 505 to move, and then the sliding plate 503 moves, and then drives the rectangular block 504 to move, so that the rectangular block 504 is disengaged from the locking groove, and then the clamping cylinder 201 can be taken out. When installing the clamping cylinder 201, the clamping cylinder 201 can be directly installed through the inclination angle of one end of the rectangular block 504, and the clamping cylinder 201 is limited by the baffle 501 and the locking cavity 502, and the sliding plate 503 is fixed by the compression spring 506, so that the rectangular block 504 is clamped in the locking cavity 502.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
