Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to a portable lighting fixture capable of rapidly switching laser beams. Background Technology

[0002] Traditional portable lighting fixtures rely on LED spotlights and floodlights, but the light beams they emit are severely scattered in smoke, making them unable to provide effective illumination in environments with low visibility, such as smoke.

[0003] To enable lighting fixtures to provide effective illumination in low-visibility environments such as those with smoke, designers have experimented with incorporating lasers into the fixtures. Furthermore, to allow the lighting fixtures to flexibly adapt to various complex working environments, different types of lenses need to be replaced, allowing the laser to emit different types of laser beams after passing through the lenses (e.g., linear laser beams, cross laser beams, point laser beams).

[0004] Designing a laser dial assembly that incorporates different types of lenses and allows for rapid switching of laser beams through rotation is a key technical challenge for designers. Furthermore, lighting fixtures are used in various unpredictable environments (extreme cold or heat), where temperature changes cause thermal expansion and contraction of the fixture housing. Since the laser dial assembly and the fixture housing are in sliding frictional contact, the frictional force of the laser dial assembly can become unstable (loose or tight). Adapting the laser dial assembly to improve its smooth rotation is another technical issue that designers need to consider in depth. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a portable lighting fixture that can quickly switch laser beams.

[0006] The objective of this invention is achieved through the following technical solution: A portable lighting fixture capable of quickly switching laser beams includes: a housing, a laser source, a focusing source, a laser dial assembly, a laser protective cover, and a focusing protective cover; The laser source and the focusing source are disposed inside the housing. The surface of the housing has laser through holes and focusing through holes corresponding to the laser source and the focusing source, respectively. The surface of the housing has a receiving groove around the laser through hole and an annular groove around the focusing through hole. The laser dial assembly includes an actuating part and a lens mounting part connected to each other; the actuating part is a ring structure, the actuating part is rotatably sleeved on the outer ring of the annular groove, the inner ring of the actuating part is provided with a plurality of roller needles, the plurality of roller needles abut against the outer ring of the annular groove, the lens mounting part is received in the receiving groove, and a plurality of laser lenses are mounted on the lens mounting part. The laser protective cover is fitted into the opening of the receiving groove, and the focusing protective cover is spirally wound around the inner ring of the annular groove.

[0007] In one embodiment, The inner ring of the annular groove is provided with an inner extrusion ring, and the outer ring of the light-concentrating protective cover is provided with an outer extrusion ring. The transverse surfaces of the inner extrusion ring and the outer extrusion ring are wedge-shaped structures. The inner extrusion ring has an inner extrusion inclined surface, and the outer extrusion ring has an outer extrusion inclined surface. The inner ring of the annular groove has an internal thread, and the outer ring of the focusing protective cover has an external thread; the external thread and the internal thread are screwed together so that the inner extrusion ring and the outer extrusion ring are squeezed against each other, thereby causing the annular groove to undergo elastic deformation in the circumferential direction, and then causing the outer ring of the annular groove to abut against a plurality of the needle rollers.

[0008] In one embodiment, the bottom of the receiving groove is provided with a plurality of positioning grooves, which are arranged in an arc shape at intervals. The lens mounting part is provided with positioning balls that cooperate with the plurality of positioning grooves.

[0009] In one embodiment, the laser protective cover is provided with a sliding guide groove, which is a continuous arc-shaped groove structure, and the lens mounting part is provided with a sliding ball that cooperates with the sliding guide groove.

[0010] In one embodiment, the lens mounting part has a plurality of lens mounting holes, which are arranged in an arc shape at intervals, and each laser lens is installed in each lens mounting hole in a corresponding manner; the laser protective cover has a laser output hole corresponding to the laser through hole, and the laser through hole and the laser output hole form a laser channel, and one of the plurality of lens mounting holes is located in the laser channel.

[0011] In one embodiment, the laser lenses are respectively: a line laser lens, a plane lens, and a cross laser lens.

[0012] In one embodiment, the outer ring of the actuating part has an anti-slip tooth structure.

[0013] In one embodiment, the portable lighting fixture capable of rapidly switching laser beams also includes a chest clip assembly disposed on the housing.

[0014] In one embodiment, the housing is provided with a heat sink at the laser light source.

[0015] In one embodiment, the portable lighting fixture capable of rapidly switching laser beams further includes a power supply component electrically connected to the laser source and the focusing source.

[0016] This invention relates to a portable lighting fixture capable of rapidly switching laser beams. It features a laser dial assembly with several laser lenses mounted on a lens mounting section. By rotating the dial assembly according to actual conditions, the laser lenses can be selectively aligned with the laser source, thereby emitting different laser beams and achieving rapid switching of the laser beam.

[0017] Furthermore, during the process of the focusing protective cover being screwed into the inner ring of the annular groove, the inner and outer extrusion rings with their special structure will press against each other, thereby causing the annular groove to undergo elastic deformation along the circumference. This, in turn, causes the outer ring of the annular groove to abut against several needle rollers. By loosening or tightening the focusing protective cover, the friction force can be adjusted to adapt to the thermal expansion and contraction caused by temperature changes, ultimately allowing the actuating part to rotate stably and smoothly.

[0023] This invention discloses a portable lighting fixture 10 capable of rapidly switching laser beams, comprising: a housing 100 (e.g., ... Figure 1 As shown), laser source 200 (e.g.) Figure 2 As shown), a focused light source 300 (such as...) Figure 2 As shown), laser dial assembly 400 (as shown) Figure 3 , 4 As shown), laser protective cover 500 (as shown) Figure 3 , 4 As shown), light-concentrating protective cover 600 (as shown) Figure 3 , 4 (As shown).

[0024] like Figure 2 As shown, the laser light source 200 and the focusing light source 300 are disposed inside the housing 100, as... Figure 3 As shown, the surface of the housing 100 has laser passage holes 210 and focusing passage holes 310 corresponding to the laser light source 200 and focusing light source 300, respectively. Figure 3 As shown, a receiving groove 110 is formed on the surface of the housing 100 around the laser through hole 210, and an annular groove 120 is formed on the surface of the housing 100 around the focusing through hole 310.

[0025] like Figure 5As shown, the laser dial assembly 400 includes an actuating part 410 and a lens mounting part 420 connected to each other. The actuating part 410 has a ring structure and is rotatably fitted onto the outer ring of the annular groove 120 (see [reference]). Figure 2 The inner ring of the actuating part 410 is provided with a plurality of needle rollers 430, which abut against the outer ring of the annular groove 120. The lens mounting part 420 is received in the receiving groove 110 (see [reference]). Figure 2 Several laser lenses 440 (such as) are mounted on the lens mounting section 420. Figure 5 (As shown).

[0026] like Figure 1 and Figure 2 As shown, the laser protection cover 500 is snapped into the slot of the receiving groove 110, and the focusing protection cover 600 is spirally attached to the inner ring of the annular groove 120.

[0027] The assembly process and working principle of the portable lighting fixture 10 with rapidly switchable laser beams described above will be explained below: Several laser lenses 440 are mounted on the lens mounting part 420. For example, the several laser lenses 440 are: a line laser lens, a plane lens, and a cross laser lens. When the laser emitted by the laser source 200 passes through the line laser lens, it will emit a line-shaped laser beam. When the laser emitted by the laser source 200 passes through the plane lens, it will emit a dot laser beam. When the laser emitted by the laser source 200 passes through the cross laser lens, it will emit a cross-shaped laser beam. The actuating part 410 is sleeved on the outer ring of the annular groove 120, while the lens mounting part 420 is received in the receiving groove 110. Since the inner ring of the actuating part 410 is provided with a number of rollers 430, the actuating part 410 can rotate around the outer ring of the annular groove 120 through the number of rollers 430. The laser protective cover 500 is snapped into the groove of the receiving groove 110, so that the lens mounting part 420 is sealed in the receiving groove 110. The concentrator cover 600 is screwed into the inner ring of the annular groove 120. On the one hand, the concentrator cover 600 can isolate and protect the concentrator light source 300. On the other hand, the concentrator cover 600 limits the movement of the actuating part 410 from falling off the outer ring of the annular groove 120. By rotating the actuating part 410, one of the laser lenses 440 on the lens mounting part 420 is selectively positioned to correspond to the laser source 200. Each laser lens 440 has a different structure; therefore, the laser emitted from the laser source 200 will emit different laser beams after passing through lenses with different structures. Figure 5As shown, in this embodiment, the laser lenses 440 are respectively: a line laser lens 441, a plane lens 442, and a cross laser lens 443. When the laser emitted by the laser source 200 passes through the line laser lens, it will emit a line-shaped laser beam. When the laser emitted by the laser source 200 passes through the plane lens, it will emit a dot laser beam. When the laser emitted by the laser source 200 passes through the cross laser lens, it will emit a cross-shaped laser beam. like Figure 5 As shown, specifically, the lens mounting part 420 has a plurality of lens mounting holes 421, which are arranged in an arc shape at intervals. Each laser lens 440 is installed in each lens mounting hole 421 in a corresponding manner. The laser protective cover 500 has a laser light emitting hole 501 corresponding to the laser passing hole 210 (e.g., ...). Figure 3 As shown), the laser passes through hole 210 and laser output hole 501 to form a laser channel, and several lens mounting holes 421 are selectively located in the laser channel; The Concentrated Light Source 300 also features a red and blue flashing warning mode, which can flexibly cope with various complex working environments; It should be noted that the portable lighting fixture 10, which can quickly switch laser beams, also includes a power supply assembly 700 electrically connected to the laser light source 200 and the focusing light source 300 (e.g., Figure 2 As shown), the power supply assembly 700 is used to provide power to the laser light source 200 and the focusing light source 300; Because the laser source 200 generates a large amount of heat during operation, a heat sink 800 is provided in the housing 100 at the location of the laser source 200 to improve heat dissipation (e.g., ...). Figure 1 (as shown) In this invention, the portable lighting fixture 10 capable of rapidly switching laser beams also includes a chest clip assembly 900 disposed on the housing 100 (e.g., Figure 1 As shown in the figure, in addition to holding the lighting fixture in your hand, you can also clamp the lighting fixture onto an object using the chest clamp assembly 900.

[0028] This invention relates to a portable lighting fixture 10 capable of quickly switching laser beams. It primarily features a laser dial assembly 400, on which several laser lenses 440 are mounted on a lens mounting section 420. By rotating the dial section 410 according to actual needs, one of the laser lenses 440 is selectively positioned to correspond with the laser source 200, thereby emitting different laser beams and achieving rapid switching of the laser beam. Traditionally, laser lenses of different structures are placed outside the lighting fixture. When a specific type of laser lens is needed, the current lens is removed, and then another lens is installed. This method is not only cumbersome but also prone to the loss of laser lenses.

[0029] As can be seen from the above structure, the actuating part 410 is sleeved on the outer ring of the annular groove 120 by a plurality of rollers 430. The arrangement of the plurality of rollers 430 reduces the contact area between the actuating part 410 and the outer ring of the annular groove 120, thereby reducing the friction and allowing the actuating part 410 to rotate more smoothly around the outer ring of the annular groove 120.

[0030] The lighting fixture of the present invention will be used in various uncertain environments (severe cold or extreme heat). Temperature changes will cause thermal expansion and contraction of the fixture housing. The sliding friction between the needle rollers 430 on the actuating part 410 and the outer ring of the annular groove 120 will cause the friction between the needle rollers 430 and the outer ring of the annular groove 120 to be unstable. This will cause the actuating part 410 to be loosely fitted onto the outer ring of the annular groove 120, or to be too tightly fitted onto the outer ring of the annular groove 120, both of which will affect the stability of use.

[0031] To solve this technical problem, in this invention, as follows: Figure 2 As shown, the inner ring of the annular groove 120 is provided with an inner extrusion ring 121, and the outer ring of the focusing protective cover 600 is provided with an outer extrusion ring 601. The transverse surfaces of the inner extrusion ring 121 and the outer extrusion ring 601 are wedge-shaped structures, and the inner extrusion ring 121 has an inner extrusion inclined surface 1211 (as shown). Figure 3 As shown), the outer extrusion ring 601 has an outer extrusion inclined surface 6011 (as shown). Figure 4 (As shown).

[0032] like Figure 2 As shown, the inner ring of the annular groove 120 has an internal thread 122, and the outer ring of the focusing protective cover 600 has an external thread 602. The external thread 602 and the internal thread 122 are screwed together so that the inner compression ring 121 and the outer compression ring 601 are squeezed together, thereby causing the annular groove 120 to undergo elastic deformation in the circumferential direction, and then causing the outer ring of the annular groove 120 to abut against a number of needle rollers 430.

[0033] The external thread 602 and the internal thread 122 are screwed together, allowing the focusing protective cover 600 to be screwed onto the inner ring of the annular groove 120, thus achieving the installation of the focusing protective cover 600. When the actuating part 410 is felt to be loosely fitted onto the outer ring of the annular groove 120, it is necessary to appropriately increase the friction between the needle rollers 430 and the outer ring of the annular groove 120. This allows the focusing protective cover 600 to be tightened appropriately in the forward direction, causing the inner compression ring 121 and the outer compression ring 601 to press against each other. During the process of the inner compression ring 121 and the outer compression ring 601 pressing against each other, the annular groove 120 will undergo elastic deformation in the circumferential direction. This circumferential elastic deformation will make the outer ring of the annular groove 120 more tightly abut against the needle rollers 430, increasing the friction between the needle rollers 430 and the outer ring of the annular groove 120. When it is felt that the actuating part 410 is too tightly fitted onto the outer ring of the annular groove 120, it is necessary to appropriately reduce the friction between the needle roller 430 and the outer ring of the annular groove 120. The focusing protective cover 600 can be loosened appropriately in the opposite direction to reduce the squeezing force between the inner squeezing ring 121 and the outer squeezing ring 601. The elastic deformation of the annular groove 120 along the circumference will also be reduced accordingly, thereby reducing the friction between the needle roller 430 and the outer ring of the annular groove 120.

[0034] The annular groove 120 in this invention has the following functions and effects: 1. The focusing protective cover 600 is screwed into the inner ring of the annular groove 120, thus realizing the installation of the protective cover; 2. The actuating part 410 is rotatably sleeved in the outer ring of the annular groove 120, realizing the rotation adjustment and installation of the actuating part 410; 3. During the process of the focusing protective cover 600 being screwed into the inner ring of the annular groove 120, the inner extrusion ring 121 and the outer extrusion ring 601 with their special structure will press against each other, thereby causing the annular groove 120 to undergo elastic deformation in the circumferential direction. Then, the outer ring of the annular groove 120 abuts against several needle rollers 430. By loosening or tightening the focusing protective cover 600, the friction force can be adjusted to adapt to the thermal expansion and contraction caused by temperature changes, so that the actuating part 410 can rotate stably and smoothly.

[0035] In this invention, the bottom of the receiving groove 110 is provided with a plurality of positioning grooves 111 (e.g., Figure 3 As shown), a plurality of positioning grooves 111 are arranged in an arc shape at intervals, and the lens mounting part 420 is provided with positioning balls 422 that mate with the plurality of positioning grooves 111 (as shown). Figure 4 (As shown). In this embodiment, three positioning grooves 111 are provided. When the toggle part 410 is rotated and adjusted, the lens mounting part 420 will also rotate accordingly. When it reaches a certain position, a "click" sound will be heard, that is, the positioning ball 422 is just stuck in a certain positioning groove 111, which proves that the lens mounting part 420 has rotated into place and a certain lens has been accurately positioned in the laser channel.

[0036] In this invention, the laser protective cover 500 is provided with a sliding guide groove 502 (e.g., Figure 4 As shown), the sliding guide groove 502 is a continuous arc-shaped groove structure, and the lens mounting part 420 is provided with sliding balls 423 that cooperate with the sliding guide groove 502 (as shown). Figure 3 (As shown). By setting the mutually cooperating sliding guide groove 502 and sliding ball 423, the lens mounting part 420 can travel along a predetermined route, improving stability.

[0037] In this invention, the outer ring of the actuating part 410 has an anti-slip tooth structure 411 (e.g., Figure 5 As shown, by setting the anti-slip serrated structure 411, the actuating part 410 can be actuated more effectively, preventing slippage.

[0038] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
