Description

Technical Field

[0001] The utility model relates to the field of beam angle adjustment of lamps, and particularly relates to a beam angle structure applied to lamps. Background Art

[0002] The beam angle of a lamp refers to the included angle between the 1 / 10 maximum light intensities of the lamp, which is used to describe the category of floodlights. The larger the beam angle, the larger the illumination range projected by the lamp on the ground, and the smaller the beam angle, the smaller the illumination range projected by the lamp on the ground.

[0003] Conventionally, the beam angle adjustment of lamps is usually achieved by replacing lenses or reflectors with different angles. Although this method is feasible, it is cumbersome to operate and costly. At the same time, the installation of lenses is mostly fixed by fasteners such as screws. Although it is firm, it is extremely inconvenient to disassemble and replace. It is impossible to achieve fast and simple beam angle adjustment and lens installation and disassembly, and the maintenance cost is high, which is not conducive to users to flexibly adjust the lighting effect of lamps according to actual needs. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a beam angle structure applied to lamps that can not only achieve automatic adjustment of the beam angle but also achieve rapid disassembly and replacement of the light-transmitting lens in view of the current situation of the prior art.

[0005] The utility model is realized by the following technical solutions: The utility model provides a beam angle structure applied to lamps, including a lamp body. A reflector is installed on the outer periphery of the bottom end of the lamp body. A beam angle adjustment mechanism is installed between the top end of the reflector and the outer wall of the lamp body. A light-transmitting lens is also installed at the middle part of the bottom end of the lamp body through a quick-release assembly. The beam angle adjustment mechanism includes a mounting ring installed in the middle of the outer wall of the lamp body, a toothed ring rotatably installed at the bottom end of the mounting ring, driving motors symmetrically installed on both sides of the upper end of the mounting ring, gear shafts installed on the power output shafts of each driving motor, guiding telescopic rods symmetrically installed on both sides of the bottom end of the toothed ring, a connecting ring platform installed on the telescopic part of the guiding telescopic rod, and a threaded part opened at the lower outer part of the lamp body to cooperate with the upper part of the reflector. The quick-release assembly includes three limiting grooves annularly opened on the outer periphery of the light-transmitting lens, a dial plate installed at the bottom end of the lamp body opposite to the limiting grooves, and a snap spring shaft installed in the middle of the dial plate.

[0006] By adopting the above technical solution, when the lamp body is actually in use, the driving motor can be used to drive the gear shaft to rotate, so as to drive the rotation of the toothed ring, the guiding telescopic rod and the connecting ring platform through the gear shaft. While the connecting ring platform rotates, the reflecting cover will move upward along the threaded part. At this time, the guiding telescopic rod shrinks. While the reflecting cover moves upward along the threaded part, the beam angle of the lamp body will change, so as to realize the automatic and efficient adjustment of the beam angle of the lamp. At the same time, by pulling out the dial plate from the limiting groove in the light-transmitting mirror, the light-transmitting mirror can be quickly detached and replaced under the action of its own weight.

[0007] Further, a scale groove for indicating the size of the beam angle is also formed on the outer wall of the lamp body at the position of the threaded part.

[0008] By adopting the above technical solution, the angle value of the beam angle is marked in the scale groove. As the top end of the reflecting cover aligns with the corresponding beam angle scale line in the scale groove, the staff can conveniently know the size of the beam angle of the lamp body.

[0009] Further, the outer side of the gear shaft meshes with the toothed ring, the gear shaft is key-connected to the power output shaft of the driving motor, and the gear shaft is rotatably connected to the mounting ring.

[0010] By adopting the above technical solution, it is ensured that the toothed ring can be conveniently rotated under the action of the gear shaft after the driving motor is started.

[0011] Further, the fixed part of the guiding telescopic rod is welded to the mounting ring, and the telescopic part of the guiding telescopic rod is bolted to the connecting ring platform.

[0012] By adopting the above technical solution, after the toothed ring rotates, it will drive the connecting ring platform and the reflecting cover to rotate by means of the guiding telescopic rod. When the reflecting cover rotates along the threaded part, it will move upward. At this time, the telescopic part of the guiding telescopic rod retracts into the fixed part to ensure the normal screwing and upward movement of the reflecting cover.

[0013] Further, the connecting ring platform is bolted to the reflecting cover, and the reflecting cover is composed of a straight barrel part and a conical reflecting part.

[0014] By adopting the above technical solution, the reflecting cover is mainly used for concentrating light to ensure the lighting range of the lamp body.

[0015] Further, the straight barrel part of the reflecting cover is screwed with the threaded part, and the threaded part is formed on the lamp body.

[0016] By adopting the above technical solution, it can ensure the reliable screwing of the reflecting cover and the lamp body.

[0017] Further, the limiting groove is formed on the light-transmitting mirror. Both ends of the snap spring shaft are rotatably connected to the lamp body, and the snap spring provided in the middle of the snap spring shaft is fixedly connected to the dial plate.

[0018] By adopting the above technical solution, the snap spring shaft can realize the automatic reset of the dial plate after being toggled.

[0019] Further, the positions of the lamp body where the dial plate and the snap spring shaft are located are both hollow structures.

[0020] By adopting the above technical solution, the reliable installation and fixation of the dial plate on the lamp body can be ensured.

[0021] The utility model has the following beneficial effects compared with the prior art:

[0022] In the utility model, by installing a beam angle adjusting mechanism on the lamp body, when the lamp body is actually used, the driving motor can be used to drive the gear shaft to rotate, so as to drive the rotation of the toothed ring, the guiding telescopic rod and the connecting ring platform through the gear shaft. While the connecting ring platform rotates, the reflecting cover will move upward along the threaded part. At this time, the guiding telescopic rod contracts. While the reflecting cover moves upward along the threaded part, the beam angle of the lamp body will change, so as to realize the automatic and efficient adjustment of the beam angle of the lamp. At the same time, by pulling out the dial plate from the limiting groove in the light-transmitting mirror, the light-transmitting mirror can be quickly detached under the action of its own weight, eliminating the cumbersome operation of disassembling and assembling by removing screws, and making the replacement efficiency of the light-transmitting mirror higher.

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a beam angle structure applied to a lamp comprises a lamp body 1, a reflector 3 is installed on the periphery of the bottom end of the lamp body 1, a beam angle adjustment mechanism 2 is installed between the top of the reflector 3 and the outer wall of the lamp body 1, and a light-transmitting mirror 5 is installed at the middle of the bottom end of the lamp body 1 through a quick-release component 6, wherein the beam angle adjustment mechanism 2 comprises a mounting ring 202 installed at the middle of the outer wall of the lamp body 1, a gear ring 207 rotatably installed at the bottom end of the mounting ring 202, drive motors 201 symmetrically installed on both sides of the upper end of the mounting ring 202, and a power gear 207 installed at each drive motor 201. The gear shaft 206 on the output shaft, the guide telescopic rod 203 symmetrically installed on both sides of the bottom end of the gear ring 207, the connecting ring 204 installed on the telescopic part of the guide telescopic rod 203, and the threaded part 205 opened on the lower part of the outer part of the lamp body 1 and matched with the upper part of the reflector 3, the quick-release assembly 6 includes three limit grooves 603 opened in a ring shape on the periphery of the light-transmitting mirror, a dial plate 602 installed at the bottom end of the lamp body 1 facing the limit grooves 603, and a spring shaft 601 installed in the middle of the dial plate 602. The spring shaft 601 can realize the automatic reset of the dial plate 602 after being dialed.

[0033] Among them, when the lamp body 1 is actually used, the driving motor 201 can be used to drive the gear shaft 206 to rotate, so as to drive the rotation of the toothed ring 207, the guiding telescopic rod 203 and the connecting ring platform 204 through the gear shaft 206. While the connecting ring platform 204 rotates, it will cause the reflecting cover 3 to move upward along the threaded part 205. At this time, the guiding telescopic rod 203 contracts. While the reflecting cover 3 moves upward along the threaded part 205, it will change the beam angle of the lamp body 1, so as to realize the automatic and efficient adjustment of the beam angle of the lamp. At the same time, by pulling out the dial plate 602 from the limiting groove 603 in the light-transmitting mirror 5, the light-transmitting mirror 5 can be quickly detached and replaced under its own weight.

[0034] As Figure 1 shown, in this embodiment, a scale groove 4 for indicating the size of the beam angle is also provided on the outer wall of the lamp body 1 at the threaded part 205. The scale groove 4 indicates the angle value of the beam angle. As the top of the reflecting cover 3 aligns with the corresponding beam angle scale line in the scale groove 4, the staff can conveniently know the size of the beam angle of the lamp body 1.

[0035] As Figures 1-3 shown, in this embodiment, the gear shaft 206 meshes with the outer side of the toothed ring 207. The gear shaft 206 is key-connected to the power output shaft of the driving motor 201, and the gear shaft 206 is rotatably connected to the mounting ring 202, ensuring that the toothed ring 207 can be conveniently rotated under the action of the gear shaft 206 after the driving motor 201 is started.

[0036] As Figure 1 、 Figure 2 and Figure 6 shown, in this embodiment, the fixed part of the guiding telescopic rod 203 is welded to the mounting ring 202, and the telescopic part of the guiding telescopic rod 203 is bolted to the connecting ring platform 204. After the toothed ring 207 rotates, it will drive the connecting ring platform 204 and the reflecting cover 3 to rotate with the help of the guiding telescopic rod 203. When the reflecting cover 3 rotates along the threaded part 205, it will move upward. At this time, the telescopic part of the guiding telescopic rod 203 retracts into the fixed part to ensure the normal screwing and upward movement of the reflecting cover 3. The connecting ring platform 204 is bolted to the reflecting cover 3. The reflecting cover 3 is composed of a straight cylinder part and a conical reflecting part. The reflecting cover 3 is mainly used for condensing light to ensure the lighting range of the lamp body 1.

[0037] As Figure 2 、 Figure 4 and Figure 5As shown, in this embodiment, the straight tube portion of the reflector 3 is screwed with the threaded portion 205, and the threaded portion 205 is formed on the lamp body 1, which can ensure the reliable screwing of the reflector 3 and the lamp body 1. The limiting groove 603 is formed on the light-transmitting lens 5. Both ends of the snap spring shaft 601 are rotatably connected to the lamp body 1. The snap spring provided in the middle of the snap spring shaft 601 is fixedly connected to the dial plate 602. The positions of the lamp body 1 where the dial plate 602 and the snap spring shaft 601 are located are both hollow structures, which can ensure the reliable installation and fixation of the dial plate 602 on the lamp body 1.

[0038] The specific implementation process of this embodiment is as follows: During use, first install the beam angle adjustment mechanism 2 and the quick-release assembly 6 on the lamp body 1 respectively, and then the lamp can be put into use. When adjusting the beam angle during use, the driving motor 201 drives the gear shaft 206 to rotate. After the gear shaft 206 rotates, it drives the rotation of the gear ring 207, the guiding telescopic rod 203, and the connecting ring platform 204. While the connecting ring platform 204 rotates, it moves the reflector 3 upward along the threaded portion 205. At this time, the guiding telescopic rod 203 contracts. When the reflector 3 moves upward along the threaded portion 205, it changes the beam angle of the lamp body 1, so as to realize the automatic and efficient adjustment of the beam angle of the lamp. When it is necessary to disassemble and replace the light-transmitting lens 5, just pull out the dial plate 602 from the limiting groove 603 in the light-transmitting lens 5, and the light-transmitting lens 5 can be quickly detached and replaced under its own weight, saving the cumbersome operation of disassembling and assembling screws, and making the replacement efficiency of the light-transmitting lens 5 higher.
