Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically a portable integrated communication and lighting device. Background Technology

[0002] In outdoor rescue, field inspection, emergency rescue, and security duty scenarios, staff usually need to carry both portable lighting equipment and independent walkie-talkie communication equipment. Carrying the two sets of equipment separately not only increases the weight and makes it cumbersome to use and switch between them, but also makes them prone to loss or being left behind. Integrated communication and lighting equipment has become the mainstream direction of industry development.

[0003] Existing integrated lighting communication products often employ a rotating lamp head, external telescopic lens, or single reflector cup segmented adjustment method for dimming. This only allows for fixed-level switching between focused and floodlight, and cannot continuously and smoothly adjust the beam's illumination range and distance. During adjustment, the light spot may exhibit discontinuities and abrupt changes in brightness, making it difficult to adapt to diverse scenario requirements such as close-range large-area environmental inspection, mid-range mixed lighting, and long-range target search. Traditional sliding focusing components lack an adaptive damping locking structure. Under running, bumpy, or vibrating conditions, the sliding parts are prone to self-displacement, causing the beam to suddenly diverge or become over-focused, severely interfering with the field of vision. At the same time, conventional internal and external reflector optical path structures are simple, resulting in poor light uniformity in floodlight mode and low light focusing efficiency and significant light loss in focused mode.

[0004] Furthermore, the existing equipment's lighting optical path and communication module are controlled independently, requiring separate operation of the lighting level and communication channel switch, which is cumbersome. It cannot automatically match the communication power and intercom mode according to the lighting distance. There is a lack of effective isolation between the communication radio frequency signal and the lighting drive circuit, which can easily generate electromagnetic interference, causing intercom noise and light flickering. In addition, the communication module is often in a standby state with constant power, continuously consuming power when idle, which significantly shortens the overall battery life of the equipment. The waterproof performance of the tail sealing structure is insufficient, and it is prone to water ingress, short circuits, and poor contact of communication contacts in outdoor rain and water wading scenarios. Overall, there are obvious shortcomings in environmental adaptability and ease of operation. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a portable integrated communication and lighting device.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A portable integrated communication and lighting device, comprising:

[0008] lighting tube;

[0009] The tube head is fixedly installed at the lighting end of the lighting tube;

[0010] A lighting fixture is installed inside the lighting cylinder near the head of the cylinder.

[0011] An outer conical cylinder is fixed inside the cylinder head, and its opening gradually increases in size along the lighting direction of the lamp;

[0012] The inner conical cylinder can slide along the length of the lighting cylinder, and the opening of the inner conical cylinder gradually decreases along the lighting direction of the lighting lamp;

[0013] in:

[0014] When the inner conical cylinder slides to the back of the lighting direction of the lamp, the light emitted by the lamp spreads outward along the inner wall of the outer conical cylinder to form diffused light; when the inner conical cylinder slides to the front of the lighting direction of the lamp, the light emitted by the lamp converges along the inner wall of the inner conical cylinder to form focused light; by adjusting the sliding position of the inner conical cylinder in front of the lamp, the illumination range and distance of the focused beam can be continuously adjusted.

[0015] Preferably, it also includes a slider fixed on the inner conical cylinder. The slider is an elastic damping slider. A closed-loop guide groove is opened axially on the inner wall of the lighting cylinder. Multiple levels of gradually changing damping grooves are arrayed along the length direction of the guide groove. The elastic damping slider and the gradually changing damping grooves are interference-fitted to form stepless damping locking of the inner conical cylinder. The damping force increases synchronously as the inner conical cylinder approaches the lighting lamp. Under strong light focusing conditions, the locking force is automatically increased to prevent the inner conical cylinder from shifting on its own under running or bumpy conditions.

[0016] Preferably, the inner wall of the outer conical cylinder is coated with a soft light diffuse reflection layer, and the inner wall of the inner conical cylinder is provided with a high light-concentrating nano-reflective film; the outer conical cylinder and the inner conical cylinder slide relative to each other to form a variable composite optical path, and the sliding stroke of the slider corresponds to the division of three optical path modes: diffuse light zone, mixed soft light zone, and strong light-concentrating zone. A single linear sliding action can simultaneously switch between the three illumination light patterns without the need for additional adjustment of the lens assembly.

[0017] Preferably, it also includes a communication module, which is integrated and embedded in the sealed cavity at the tail of the lighting tube. An electromagnetic shielding layer is set inside the sealed cavity to isolate the communication radio frequency signal from the lighting lamp driving circuit. The rear cover at the tail of the lighting tube adopts a spin-pressed double waterproof structure. The inner side of the rear cover integrates elastic conductive contacts. When the rear cover is screwed in, it automatically connects the communication module and the built-in power supply battery. When the rear cover is unscrewed, it simultaneously cuts off the communication power supply to avoid continuous power consumption of radio frequency when idle.

[0018] Preferably, it also includes a control switch, which is a multi-position linkage composite button. The control switch has a built-in linkage logic circuit, which synchronously collects the sliding position signal of the inner conical cylinder and the button trigger signal. When switching to the focusing optical path, the circuit automatically increases the output power of the lighting lamp and simultaneously opens the long-distance intercom channel of the communication module. When switching to the diffused optical path, it automatically reduces the lighting power and switches to the short-range silent communication mode, realizing adaptive linkage control of lighting pattern, communication power, and communication distance.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This device uses a sliding inner conical cylinder in conjunction with a fixed outer conical cylinder to form a composite adjustable optical path. It achieves stepless continuous switching between three optical path modes—diffuse light, mixed soft light, and focused strong light—simply by linearly sliding the inner conical cylinder along the axial direction of the illumination tube. When sliding behind the illumination lamp, it outputs uniform diffused light through the soft light layer on the inner wall of the outer conical cylinder; when sliding in front of the illumination lamp, it uses the high-concentration nano-reflective film on the inner conical cylinder to focus the light. During the sliding process, it can stop at any intermediate position to continuously adjust the beam's illumination range and distance without the need for additional lenses, focusing rings, or other components. The optical path structure is simple and compact, with low light loss and smooth light spot transitions without abrupt changes in brightness, seamlessly adapting to various scenarios such as close-range environmental inspection, mid-range work lighting, and long-range target search. Combined with an elastic damping slider and multi-level gradually changing damping grooves to form a stepless damping locking structure, it automatically increases the locking force under focused conditions when the device moves or vibrates, effectively preventing the inner conical cylinder from shifting and significantly improving beam stability. A communication module with an electromagnetic shielding layer is integrated at the rear. The RF communication circuit and lighting drive circuit are physically isolated, completely eliminating problems such as light flicker and intercom noise caused by electromagnetic interference. The spun-type double waterproof back cover has both sealing and waterproof functions as well as on / off control functions. Tightening it automatically conducts communication power supply, and unscrewing it synchronously cuts off the RF circuit, eliminating idle power consumption and extending the overall battery life. The multi-level linkage composite button has a built-in linkage logic circuit that can synchronously collect the position signal of the inner cone and the button signal to realize adaptive linkage control of lighting pattern, lighting output power and communication intercom distance. When switching the focusing light path, the lighting power is automatically increased and the long-distance intercom channel is opened. When switching the diffused light path, the lighting power is reduced and the short-distance silent communication mode is switched. A single step operation synchronously completes the matching of lighting and communication parameters, which greatly simplifies the on-site operation process. The whole device integrates continuous stepless dimming, anti-bump lock, electromagnetic compatibility waterproof communication, and optical linkage control functions into one unit. Its portability, reliability and scene adaptability are significantly better than traditional products, and it is highly suitable for complex outdoor use environments such as emergency rescue, field operations, and security patrols.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figures 1-4 As shown, a portable integrated communication and lighting device includes:

[0031] lighting tube 1;

[0032] The tube head 11 is fixedly installed at the lighting end of the lighting tube 1;

[0033] The lighting lamp 12 is installed inside the end of the lighting cylinder 1 near the head 11;

[0034] The outer conical cylinder 2 is fixed inside the cylinder head 11, and its opening gradually increases along the lighting direction of the lighting lamp 12;

[0035] The inner conical cylinder 3 can slide along the length of the lighting cylinder 1, and the opening of the inner conical cylinder 3 gradually decreases along the lighting direction of the lighting lamp 12;

[0036] It also includes a slider 31 fixed on the inner conical cylinder 3. The slider 31 is an elastic damping slider. A closed-loop guide groove is opened axially on the inner wall of the lighting cylinder 1. Multiple levels of gradually changing damping grooves are arrayed along the length direction in the guide groove. The elastic damping slider 31 is interference-fitted with the gradually changing damping grooves to form a stepless damping lock for the inner conical cylinder 3. The damping force increases synchronously as the inner conical cylinder 3 approaches the lighting lamp 12. Under strong light focusing conditions, the locking force is automatically increased to prevent the inner conical cylinder 3 from shifting on its own under running or bumpy conditions.

[0037] The inner wall of the outer conical cylinder 2 is coated with a soft light diffuse reflection layer, and the inner wall of the inner conical cylinder 3 is provided with a high light-concentrating nano reflective film. The outer conical cylinder 2 and the inner conical cylinder 3 slide relative to each other to form a variable composite optical path. The sliding stroke of the slider 31 corresponds to the division of three optical path modes: diffuse light zone, mixed soft light zone, and strong light-concentrating zone. A single linear sliding action can simultaneously switch between the three illumination light patterns without the need for additional adjustment of the lens assembly.

[0038] in:

[0039] When the inner conical cylinder 3 slides to the back of the illumination direction of the lamp 12, the light emitted by the lamp 12 expands outward along the inner wall of the outer conical cylinder 2 to form diffused light; when the inner conical cylinder 3 slides to the front of the illumination direction of the lamp 12, the light emitted by the lamp 12 converges along the inner wall of the inner conical cylinder 3 to form focused light; by adjusting the sliding position of the inner conical cylinder 3 in front of the lamp 12, the illumination range and distance of the focused beam can be continuously adjusted.

[0040] Specifically, this device uses the lighting cylinder 1 as the supporting base, and relies on the fixedly assembled outer conical cylinder 2 and the axially sliding inner conical cylinder 3 to form a double-conical composite reflective light path. By driving the elastic damping slider 31 on the inner conical cylinder 3 to move along the guide groove on the inner wall of the lighting cylinder 1, the front and rear positions of the inner conical cylinder 3 relative to the lighting lamp 12 are changed, switching between three light paths: diffuse light zone, mixed soft light zone, and strong light focusing zone, realizing stepless continuous adjustment of the beam. The multi-level gradual damping groove and the elastic damping slider 31 are interference fit to form a damping locking structure, which automatically increases the locking damping as the inner conical cylinder 3 approaches the lighting lamp 12 to prevent the light path structure from shifting due to bumps or running. The soft light diffuse reflection layer on the inner wall of the outer conical cylinder 2 and the high light focusing nano reflective film on the inner wall of the inner conical cylinder 3 work together to achieve uniform floodlight and efficient light focusing, respectively. The switching of the full light pattern can be completed with only a single linear slide, without the need for additional lens adjustment components.

[0041] In diffused light mode, manually push the inner conical cylinder 3 to move the slider 31 backward along the closed-loop guide groove inside the lighting cylinder 1, so that the inner conical cylinder 3 is completely back behind the lighting lamp 12; the slider 31 stops at the gradually damped groove corresponding to the diffused light area of ​​the groove, and the damping is locked by interference fit to keep the inner conical cylinder 3 in a fixed position; the lighting lamp 12 is powered on and emits light, and the light is directly projected into the outer conical cylinder 2 fixed inside the cylinder head 11 without obstruction; the light undergoes uniform diffuse reflection in the soft light diffuse reflection layer on the inner wall of the outer conical cylinder 2, and diffuses outward along the gradually expanding opening of the outer conical cylinder 2, outputting a wide range of soft diffused light, which is suitable for close-range inspection operations.

[0042] In the mixed soft light mode, slide the inner cone 3 forward, and the slider 31 moves to the damping slot corresponding to the mixed soft light area of ​​the slide groove. The inner cone 3 partially blocks the light path of the lighting lamp 12. The slider 31 and the slot cooperate to form a medium damping lock, stabilizing the current middle position. The light emitted by the lighting lamp 12 is divided into two parts: one part diffuses outward through the soft light diffuse reflection layer of the outer cone 2, and the other part is gathered inward through the high light focusing nano reflective film of the inner cone 3. The diffused light and the gathered light are superimposed and merged to form a mixed soft light with a smooth transition between light and dark, which is suitable for medium-distance comprehensive lighting scenes.

[0043] In the focused high-intensity light mode, the inner conical cylinder 3 is continuously pushed forward, and the slider 31 slides to the gradually damped groove corresponding to the high-intensity light focusing area of ​​the slide groove. The inner conical cylinder 3 completely covers the front of the lighting lamp 12. Because the inner conical cylinder 3 is close to the lighting lamp 12, the damping force of the slide groove increases synchronously, and the interference locking force of the slider 31 is increased, so it will not move backward on its own in running or bumpy environments. All the light from the lighting lamp 12 is projected onto the high-intensity light-concentrating nano-reflective film on the inner wall of the inner conical cylinder 3. The light converges and gathers inward along the gradually narrowing inner wall of the inner conical cylinder 3, forming a high-brightness, long-distance focused high-intensity light. By finely adjusting the position of the inner conical cylinder 3 in front of the lighting lamp 12, the degree of beam focusing can be continuously changed, and the beam illumination range and illumination distance can be steplessly adjusted.

[0044] Furthermore, it also includes a communication module 4, which is integrated and embedded in the sealed cavity at the tail of the lighting tube 1. An electromagnetic shielding layer is set inside the sealed cavity to isolate the communication radio frequency signal from the driving circuit of the lighting lamp 12. The rear cover at the tail of the lighting tube 1 adopts a spin-pressed double waterproof structure. The inner side of the rear cover integrates elastic conductive contacts. When the rear cover is screwed in, it automatically connects the communication module 4 and the built-in power supply battery. When the rear cover is unscrewed, it simultaneously cuts off the communication power supply to avoid continuous power consumption of radio frequency when idle. It also includes a control switch 13, which is a multi-position linkage composite button. The control switch 13 has a built-in linkage logic circuit. The linkage logic circuit synchronously collects the sliding position signal of the inner conical tube 3 and the button trigger signal. When switching to the focusing light path, the circuit automatically increases the output power of the lighting lamp 12 and simultaneously opens the long-distance intercom channel of the communication module 4. When switching to the diffused light path, it automatically reduces the lighting power and switches to a short-range silent communication mode to realize adaptive linkage control of lighting pattern, communication power, and communication distance.

[0045] Specifically, the communication module 4 is integrated inside the sealed cavity at the tail of the lighting tube 1. The electromagnetic shielding layer inside the cavity physically isolates the radio frequency communication circuit from the driving circuit of the lighting lamp 12, eliminating electromagnetic interference. The double waterproof rear cover at the tail of the lighting tube 1 uses the inner elastic conductive contacts to control the power supply circuit of the communication module 4. Tightening it turns on the circuit and untightening it turns off the power, preventing idle radio frequency power consumption. The device is equipped with a multi-position linkage composite button control switch 13. Its internal linkage logic circuit can synchronously collect the sliding position signal of the inner conical tube 3 and the button trigger signal. According to the optical path mode, it adaptively matches the output power of the lighting lamp 12, the intercom channel and communication power of the communication module 4, realizing integrated linkage control of lighting and communication.
