[0002] A searchlight is a lighting fixture designed for specific area illumination. With its powerful beam and wide illumination range, it plays an irreplaceable role in various scenarios such as night patrols, construction, stage performances, outdoor exploration, and military operations. To achieve more flexible applications, modern searchlights are often equipped with lumen adjustment functions, allowing users to adjust the brightness of the light according to actual needs. Adjusting the lumen using a knob is an intuitive and easy-to-operate design. Rotating the knob controls the internal circuitry of the fixture, thereby adjusting the power output of the light source and changing the emitted luminous flux, i.e., the lumen value.
[0003] The existing searchlights do not have a locking mechanism for adjusting the lumen intensity knob. This makes the searchlight easy to rotate due to external impacts or other factors, causing unexpected changes in the set lumen intensity, affecting its use, resulting in poor stability and low practicality.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0024] As attached Figure 1 To be continued Figure 5 As shown:
[0025] Example 1: This utility model provides a searchlight with controllable lumens, including a lamp assembly 1 and a control assembly. The lamp assembly 1 includes a counterweight 101, a support rod 102 and a searchlight 103. The bottom end of the support rod 102 is fixed to the top of the counterweight 101, and the searchlight 103 is fixedly installed on the top of the support rod 102. The control assembly includes an adjustment mechanism 2 and a control mechanism 3.
[0026] The adjustment mechanism 2 includes a mounting base 201 and an adjustment lever 202. The mounting base 201 is fixedly installed inside the counterweight base 101, and the adjustment lever 202 is rotatably connected inside the mounting base 201. When the adjustment lever 202 is rotated, it can adjust the illumination lumen of the searchlight 103. The control mechanism 3 includes an operating knob 301, a synchronization seat 302, and a positioning worm gear 303. The operating knob 301 is inserted into the top of the mounting base 201, and the synchronization seat 302 is rotatably connected inside the operating knob 301. The synchronization seat 302 is inserted into the top of the adjustment lever 202, and the positioning worm gear 303 is rotatably connected inside the operating knob 301. The bottom of the positioning worm gear 303 is fixedly connected to the top of the synchronization seat 302.
[0027] In this embodiment, a locking spring 3021 is provided at the bottom of the synchronization base 302, and the two ends of the locking spring 3021 are respectively fixedly connected to the inside of the synchronization base 302 and the top of the adjusting rod 202. The mounting base 201 is provided with a locking tooth groove 2011 inside, and a locking gear 3011 is provided at the bottom of the operating knob 301. When the operating knob 301 is not pulled by an external force, the locking gear 3011 is inserted into the inside of the locking tooth groove 2011 under the action of the locking spring 3021. In use, the control mechanism 3 can adjust the illumination lumen of the searchlight 103 by rotating the adjusting rod 202, thereby adapting to different usage environments. The specific structure, circuit configuration and working principle of adjusting the illumination lumen of the searchlight 103 by rotating the adjusting rod 202 are existing. The technology is well-established and will not be elaborated upon here. The control mechanism 3 has a self-locking structure. When the operating knob 301 is not pulled by external force, the locking gear 3011 is inserted into the locking tooth groove 2011 under the action of the locking spring 3021, so that the operating knob 301 cannot be rotated. Since the worm gear has the characteristic of unidirectional transmission, when the adjusting worm 304 does not rotate, the operating knob 301, adjusting worm 304, positioning worm wheel 303 and synchronizing seat 302 can be used as a whole. That is, the synchronizing seat 302 will not rotate inside the operating knob 301. The synchronizing block 3022 of the synchronizing seat 302 can lock the adjusting rod 202 through the synchronizing groove 2021, so that the adjusting rod 202 cannot be rotated, thereby locking the current operating lumen value of the searchlight 103 and ensuring stable operation.
[0028] In this embodiment, the synchronization base 302 has a synchronization block 3022 inside, and the side of the adjusting knob 202 has a synchronization groove 2021. The synchronization block 3022 is inserted into the synchronization groove 2021. In use, when it is necessary to adjust the illumination lumen of the searchlight 103, simply lift and rotate the operating knob 301. When the operating knob 301 is lifted, the locking spring 3021 will be stretched, and the locking gear 3011 will disengage from the locking tooth groove 2011. Thus, the operating knob 301 can then be adjusted on the mounting base 2. The internal rotation of the control knob 301 is free. When the control knob 301 rotates, it can drive the synchronous seat 302 to rotate through the worm gear. When the synchronous seat 302 rotates, it can drive the adjusting knob 202 to rotate through the synchronous block 3022 and the synchronous groove 2021, thereby changing the illumination lumen of the searchlight 103. After the adjustment is completed, the control knob 301 is released. Under the action of the locking spring 3021, the control knob 301 will automatically move down to reset and restore the self-locking state of the control mechanism 3. The adjustment is convenient and fast, and the use is stable.
[0029] In this embodiment, the control mechanism 3 further includes an adjusting worm gear 304, which is rotatably connected inside the operating knob 301. The adjusting worm gear 304 and the positioning worm wheel 303 are connected by transmission. In use, the control mechanism 3 has a fine-tuning function, and the lumen adjustment of the searchlight 103 is delicate. When the control mechanism 3 is in the reset state (i.e., the operating knob 301 is not pulled by external force), the operating knob 301 cannot be rotated. Therefore, when the adjusting worm gear 304 is rotated alone, the adjusting worm gear 304 can drive the positioning worm wheel 303 to rotate independently of the operating knob 301. Thus, when the positioning worm wheel 303 rotates alone, it can drive the synchronous seat 302 to rotate. When the synchronous seat 302 rotates, it can drive the adjusting rod 202 to rotate, thereby controlling the illumination lumen of the searchlight 103. Moreover, the worm gear is a reduction mechanism, which makes the adjusting rod 202 rotate delicately, making it easy to accurately control the illumination lumen of the searchlight 103.
[0030] The specific usage and function of this embodiment are as follows:
[0031] In this invention, the control mechanism 3 can adjust the illumination lumens of the searchlight 103 by rotating the adjusting lever 202, thus adapting to different usage environments. The control mechanism 3 also has a self-locking structure. When the operating knob 301 is not pulled by external force, the locking gear 3011 is inserted into the locking groove 2011 under the action of the locking spring 3021, preventing the operating knob 301 from rotating. Because the worm gear has a unidirectional transmission characteristic, when the adjusting worm 304 does not rotate, the operating knob 301, adjusting worm 304, positioning worm gear 303, and synchronous seat 302 are all in a state of equilibrium. The system can be used as a whole; that is, the synchronizing base 302 will not rotate inside the operating knob 301. The synchronizing block 3022 of the synchronizing base 302 can lock the adjusting rod 202 through the synchronizing groove 2021, preventing the adjusting rod 202 from rotating and thus locking the current operating lumen value of the searchlight 103. When it is necessary to adjust the illumination lumen of the searchlight 103, simply lift and turn the operating knob 301. When the operating knob 301 is lifted, the locking spring 3021 will be stretched, and the locking gear 3011 will disengage from the locking tooth groove 2011, thus allowing the operating knob 301 to continue to rotate. The control knob 301 can rotate freely inside the mounting base 201. When the control knob 301 rotates, it drives the synchronous seat 302 to rotate through the worm gear. When the synchronous seat 302 rotates, it drives the adjusting knob 202 to rotate through the synchronous block 3022 and the synchronous groove 2021, thereby changing the illumination lumen of the searchlight 103. After the adjustment is completed, the control knob 301 is released. Under the action of the locking spring 3021, the control knob 301 will automatically move down to reset and restore the self-locking state of the control mechanism 3. The control mechanism 3 has a fine-tuning function, and the lumen adjustment of the searchlight 103 is delicate. When mechanism 3 is in the reset state (i.e., the operating knob 301 is not pulled by external force), the operating knob 301 cannot be rotated. Therefore, when the adjusting worm gear 304 is rotated alone, the adjusting worm gear 304 can drive the positioning worm wheel 303 to rotate independently of the operating knob 301. Thus, when the positioning worm wheel 303 rotates alone, it can drive the synchronous seat 302 to rotate. When the synchronous seat 302 rotates, it can drive the adjusting rod 202 to rotate, thereby controlling the illumination lumen of the searchlight 103. Moreover, the worm gear is a reduction mechanism, which makes the adjusting rod 202 rotate smoothly and facilitates precise control of the illumination lumen of the searchlight 103.
