Description

Technical Field

[0001] This disclosure relates to the field of lighting equipment technology, and more specifically, to a multifunctional lighting device. Background Technology

[0002] Handheld or wearable lighting devices are widely used in daily life, such as flashlights and clip-on lights. Common portable lighting devices are generally only equipped with white light function, providing an effective beam of light for long-distance vision or floodlight for close-range operation. For special scenarios such as maintenance, patrol, investigation, field operations, police execution, or rescue and search, existing portable lighting devices are clearly unable to meet the needs. For example, during nighttime police execution, special lighting is required to assist in evidence collection and on-site photography. In addition to lighting equipment, police officers also need to carry additional investigation lights and supplementary lights, which are not convenient to operate and are not conducive to the rapid and convenient execution of nighttime tasks. In addition, since special occasions such as patrol and police work require high waterproof performance of lighting devices, they must not only be able to perform tasks in the rain, but also not be affected by underwater immersion.

[0003] Therefore, this design proposes a multifunctional lighting device that supports illumination, detection light surveying, laser locking, and supplementary lighting functions. It has a high waterproof rating and is easy to carry and operate.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0024] This example embodiment provides a convenient, multi-functional lighting device that supports both handheld and wearable operation, such as... Figures 1-5 As shown, it includes a housing 100, a lighting panel 800, a headlight module 500, a laser 700, a colored light panel 110, a control module 300, a control circuit board 900, and a rechargeable battery. The housing 100 is a high-strength, one-piece molded housing. The interior of the housing 100 is hollow and has a battery compartment for the removable installation or replacement of rechargeable batteries. The laser 700, the lighting board 800, and the colored light board 110 are all electrically connected to the control circuit board 900 and powered by rechargeable batteries. The housing 100 has a front port and a side port for mounting the lighting board 800 and the control circuit board 900, respectively, and is sealed together by the modularly assembled front light module 500 and control module 300. The lighting panel 800 integrates the headlight drive circuit, high beam, and detection light, which is fixed to the bottom of the front port of the housing 100. A laser positioning hole is also provided at the bottom of the front port. The laser 700 is inserted into the laser positioning hole and is press-fitted and fixed by the headlight module 500. The high beam provides a high beam, the detection light provides UV light for special operations such as auxiliary surveying, counterfeit detection, and authentication, and the laser 700 can lock onto or indicate targets from a distance. In addition, by setting up a large area color light panel 110, full-color supplementary lighting is provided for night photography, which is convenient for capturing high-definition images at night; a transparent color light window is set on the front of the front of the housing 100, and the color light window is sealed by a transparent cover plate. The color light panel 110 is set in the light panel groove on the front of the housing 100 and is directly opposite the color light window. Several three-primary-color LED beads are integrated on it, and the three-primary-color LED beads are distributed in a dot matrix pattern. The control circuit board 900 is fixed to the bottom of one side port of the housing 100. It is equipped with a charging circuit and a control circuit. The control circuit generates corresponding control signals based on the input from the control module 300. A knob assembly 310, a dial assembly 320, and a charging port 330 are sequentially arranged along the length of the outer plane of the control module 300. The charging port 330 is electrically connected to the rechargeable battery and is waterproofed by a soft rubber sealing cover 331. The dial assembly 320 is used to rotate and trigger the control circuit board 900 to generate control signals to switch lighting modes. Its rotation stroke has at least four lighting levels. Based on the above light source settings, the lighting modes include at least a high beam mode, a UV light mode, a laser mode, and a fill light mode, corresponding to the on / off control of the high beam, detection light, laser 700, and colored light panel 110, respectively. Depending on common scenarios, a floodlight mode can also be considered, with the floodlight LEDs integrated with the high beam LEDs in a single light-emitting port. The knob assembly 310 is used to rotate and adjust the brightness of the light in the current lighting mode.

[0025] Specifically, the module sealing and covering involved in this embodiment includes the module sealing and installation of the headlight module 500, the control module 300, and the battery sealing cover 200. For example, the sealing of the control module 300 is achieved by setting a first mounting step 130 at the side port and opening a first sealing groove 140 for placing a sealing gasket in the first mounting step 130; a second mounting step 150 is set at the front port to limit the installation of the headlight module 500, and a sealing ring is set in the third sealing groove 530 on the headlight module 500 to achieve the sealing of the front port; a second sealing groove 230 for placing a sealing gasket is set on the battery sealing cover 200, and the sealing gasket is pressed onto the end face of the battery compartment opening when the battery sealing cover 200 is locked to achieve sealing; in addition, in order to reliably close and remove the battery sealing cover 200 at the rear compartment opening of the housing 100, a sliding safety lock 210 for the battery sealing cover 200 is set on the other side of the housing 100. The safety lock 210 locks the lock key of the battery sealing cover 200 to prevent accidental unlocking by hand.

[0026] As a further technical solution of the exemplary embodiment, in order to obtain a higher waterproof rating and improve assembly efficiency, the control module 300 is a module unit, on which a knob assembly 310 and a dial assembly 320 are assembled; specifically, the side seal is provided with a knob mounting hole and a dial mounting hole.

The sealing head on the back of the knob body 311 is connected to the knob mounting hole and is provided with a sealing ring for sealing the knob mounting hole. The sealing head is connected to the control lever 312 by a thread. The knob assembly 310 of this embodiment can realize two functions: rotating to adjust the brightness and pressing to turn the light on and off. Therefore, a return spring is provided between the sealing body and the knob body 311. Under the action of the return spring, the control lever 312 is elastically locked in the knob mounting hole. Accordingly, the control lever 312 is mechanically triggered. The control circuit board 900 is equipped with switch contacts and multiple brightness contacts in a ring array. The end of the control lever 312 is directly opposite the switch contacts. When pressed, the switch contacts are triggered to turn all lighting modes on and off. The end of the control lever 312 is square and connected to a trigger arm. The trigger arm can rotate synchronously with the control lever 312. The end contacts and triggers each brightness contact to achieve dimming at different levels. like Figure 5 As shown, the dial assembly 320 includes a dial 321 with a handle, a dial 322, and a locking ball 323. The dial 321 with a handle is easy to operate with one finger. Similarly, to improve sealing, the connector on the back of the dial 321 is connected to the pin mounting hole and is provided with a sealing ring for sealing the pin mounting hole. The connector is connected to the dial 322 by screws. To achieve more precise gear selection, the inner side of the side seal is provided with a countersunk hole for the dial 322. The dial 322 is located in the countersunk hole. At least four gear slots 360 are provided at the bottom of the countersunk hole for the dial 322, corresponding to the four light gears mentioned above. A ball hole is provided on one side of the dial 322. The locking ball 323 is elastically pressed into the ball hole and elastically extends out of the ball hole, cooperating with the gear slot 360 to precisely lock each gear. In this example embodiment, a Hall switch 910 is used for gear triggering. A magnet is provided on the other side of the dial 322 to sense the Hall switch 910. For each gear position, a Hall switch 910 is provided on the control circuit board 900 facing the magnet. Depending on the number of gears, there are at least four Hall switches 910.

[0027] In one exemplary embodiment of this disclosure, in order to improve the convenience of single-finger multi-directional operation when the lighting device is held in hand, such as Figure 1 and Figure 2As shown, a knob body recess 350 is provided on the side plane of the side seal body. The knob body 311 is located in the knob body recess 350 to prevent the knob body 311 from colliding. The front and back sides of the knob body recess 350 are open structures, forming operation ports 351 facing the front and back. The knob body 311 is provided with multiple sets of radial anti-slip stripes extending from the knob surface to the circumferential surface. Its outer knob surface protrudes out of the knob body recess 350 for upper contact adjustment. Its circumferential surface is exposed through the operation port 351 for front and side contact to operate. like Figure 1 In the handheld use state shown, the control module 300 is located on the upper plane of the housing 100. To facilitate handheld use, the other side plane of the housing 100 has a handheld groove, and an anti-slip structure 120 is provided in the handheld groove to increase handheld friction.

[0028] In an exemplary embodiment of this disclosure, similarly considering the issues of convenient operation and insufficient visibility at night, a dial groove 340 is also provided on the side plane of the side seal. A dial wheel 321 with a handle is rotatably disposed in the dial groove 340. The handle of the dial wheel 321 protrudes from the outside of the dial groove 340 for finger pushing. The two side groove surfaces of the dial groove 340 are used as stop groove surfaces 341. The two stop groove surfaces 341 are arranged radially along the dial wheel 321 and correspond to two of the light positions respectively. In this embodiment, it is set as the commonly used high beam position and the laser position with higher urgency. When the dial wheel is moved to both ends of the rotation stroke, it is blocked by the stop groove surface 341 and locked by the locking steel ball 323, which can quickly identify and reliably stop at the two positions.

[0029] In one exemplary embodiment of this disclosure, the headlight module 500 includes a front cover 510, a light-transmitting plate 520, and a reflector assembly plate 600. A white light reflector 610 and a detection light reflector 620 are arranged side-by-side on the reflector assembly plate 600 to reflect and converge the high beam and the detection light to form a beam. The reflector assembly plate 600 and the lighting plate 800 have recessed grooves on their sides. A stepped laser 700 press-fit hole is formed on the front cover 510, and the end of the laser 700 is aligned with the platform. A sealing gasket is installed between the stepped holes and is press-fitted and fixed by the front cover 510; the front cover 510 is also provided with two light cup positioning holes, the front ends of the white light cup 610 and the detection light cup 620 are inserted into the light cup positioning holes for positioning, to prevent the light cup assembly plate 600 from moving; the light-transmitting plate 520 is sealed and blocked at the bottom of the light cup positioning hole, and one end of the front cover 510 is provided with a snap-fit ​​structure, which is snapped and installed with the second mounting step 150, and then further screwed and threaded to the bottom of the front port.
