Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and in particular to a light output adjustment structure, control method, and lighting fixture. Background Technology

[0002] Lighting fixtures are core optical devices for everyday lighting, outdoor work, equipment maintenance, and other scenarios. The light output mode, spot size, and adjustable illumination range of a lighting fixture directly determine its suitability for different scenarios and its performance. The light output adjustment structure, as the core component for controlling the distribution of light in a lighting fixture, is also a key factor in determining the multi-functional lighting capabilities of the fixture.

[0003] Currently, most conventional lighting fixtures on the market adopt a fixed integrated design for their light-emitting optical structure, with the installation positions of light-emitting components such as LEDs and optical light-distributing components such as lenses and reflectors relatively fixed. Existing luminaires can only achieve a single light distribution effect, either possessing only the function of long-distance illumination with concentrated light in front, or only the function of short-distance illumination with uniform floodlight around the perimeter, unable to achieve long-distance directional illumination, and difficult to meet diverse lighting needs.

[0004] For complex applications such as outdoor adventure and cycling lighting, users often need lighting fixtures that can simultaneously provide precise, long-range focused illumination in front and wide-range, short-range floodlighting around the perimeter. However, existing lighting fixtures, limited by their fixed component assembly structures, cannot achieve relative position adjustment between the light-emitting components and optical lenses, lacking the structural basis for dynamic control. Furthermore, most do not have independent peripheral light-emitting distribution structures, making it impossible to achieve a combined light output effect that integrates both long-range and short-range illumination.

[0005] Therefore, there is a need for a lighting fixture light output adjustment structure, control method, and lighting fixture that can solve the above-mentioned defects. Summary of the Invention

[0016] This invention provides a light emission adjustment structure, control method, and lighting fixture, which have at least the following beneficial effects: 1. This invention effectively adjusts the illumination range by setting up a lens, a light-emitting component, and a focusing component. In use, the rotating sleeve is rotated, and the position of the moving rod is adjusted in conjunction with the support tube and the fixing screw, thereby changing the distance between the lamp bead and the lens, adjusting the size of the light spot in the front illumination area, and by lighting the auxiliary lamp bead at the corresponding position, the illumination range of the front illumination area is made larger, effectively increasing the front illumination area without affecting the size of the light spot produced by the lighting lamp bead.

[0017] 2. This invention adds near-field peripheral lighting by setting up a light-emitting component and a beam-splitting component. The beam-splitting component divides the light generated by the light-emitting component into two segments through physical division. The front focusing area illuminates the front of the lamp, and the rear diffused area illuminates the periphery of the lamp. Furthermore, the peripheral light is divided by a diffused ring. When in use, ensure that the shielding section corresponds to the user to avoid glare caused by the upper light.

[0018] 3. This invention reduces light energy loss by setting up a detection unit and multiple auxiliary LEDs. During use, the detection unit detects the position of the moving rod in real time. When the moving rod is detected to be close to the detection unit, the main board controls the auxiliary LEDs that have moved out of the diffused light area to turn off, realizing the intelligent switching of the LEDs, avoiding unnecessary energy loss and extending the working time.

[0019] 4. This invention adds a warning function by setting up a beam splitter and a light-emitting component. By controlling the main board to adjust the lighting state and color of the light-emitting component, and combining the beam splitter to divide the light from the front end and the side wall, the light fixture can flash or change color in different positions, so that people at a distance can observe the position of the light fixture in time.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1 This invention provides, for example Figures 1 to 7 The light emission adjustment structure of the lighting fixture shown includes a housing 1 and a lens 2 installed at one end of the housing 1. The lens 2 is a convex lens or a Fresnel lens, which can focus light to form a light spot and enhance the brightness of the light spot. Connectors can be installed on the side wall of the housing 1 as needed for installing the lighting fixture in the usage scene. It also includes: a light-emitting component 3, which is slidably installed inside the housing 1 and can slide relative to the lens 2 along the extension direction of the housing 1; a beam splitting component 4, which is fixedly installed at the end of the housing 1. The lens 2 is fixedly connected to the housing 1 through the beam splitting component 4, and one end of the light-emitting component 3 is placed inside the beam splitting component 4; and a focusing component 5, which is fixedly installed inside the housing 1. The light-emitting component 3 is installed on the side of the focusing component 5 close to the beam splitting component 4. The focusing component 5 is used to adjust the position of the light-emitting component 3 relative to the beam splitting component 4.

[0030] Specifically, the beam splitter 4 includes: a single-sided reflector 41, which is fixedly installed at one end of the housing 1; a double-sided reflector 42, which is located on the side of the single-sided reflector 41 away from the light-emitting component 3 and at a certain distance from the single-sided reflector 41; a diffusing ring 43, which is fixedly connected to the outer wall of the single-sided reflector 41; a lens 2, which is fixedly installed on the side of the double-sided reflector 42 away from the single-sided reflector 41; a focusing area 44 between the lens 2 and the double-sided reflector 42, used for forward illumination; a diffusing area 45 between the double-sided reflector 42 and the single-sided reflector 41, the diffusing area 45 corresponding to the diffusing ring 43, the diffusing ring 43 being located on the outer side of the housing 1, used for circumferential illumination of the housing 1.

[0031] It should be noted that the inner reflective surfaces of both the single-sided reflector 41 and the double-sided reflector 42 are coated with a high-reflectivity aluminum or silver film. The double-sided reflector 42 is a ring-shaped optical component with reflective surfaces on both sides.

[0032] The light-emitting adjustment structure divides the front-end optical space into two independent chambers: a focusing zone 44 and a diffused zone 45, through the physical partitioning of the beam-splitting component 4. The light-emitting component 3, as a movable light source module, allows its LEDs to switch positions between the focusing zone 44 and the diffused zone 45, thus changing which optical chamber the light enters. When the light source is located in the focusing zone 44, the light is directly reflected or reflected by the double-sided reflector 42 and then converged by the lens 2, forming a long-range focused beam. When part of the light source is located in the diffused zone 45, the light is reflected in the channel between the outer walls of the single-sided reflector 41 and the double-sided reflector 42, and finally emitted from the peripheral diffused ring 43, forming floodlight illumination. The focusing component 5, by driving the light-emitting component 3 to move back and forth, changes the distance between the light source and the focusing optical elements (lens 2 and double-sided reflector 42), thereby adjusting the size of the focused beam. It also determines whether the light source is in the focusing zone 44 or the diffused zone 45, thus switching the light-emitting mode. This structure enables a single luminaire to simultaneously possess the functions of high beam focusing, low beam flooding, and beam adjustment, solving the technical problem of limited functionality in existing luminaires with fixed optical path designs.

[0033] More specifically, the beam splitter assembly 4 also includes: a light-blocking ring 46, which is fixedly connected between the single-sided reflector 41 and the double-sided reflector 42, used to block the light from the focusing area 44 and the diffused area 45, preventing crosstalk between the two areas and ensuring the purity of the light emitted from the focusing area 44 and the diffused area 45; and a connecting ring 47, which is fixedly connected to the side of the single-sided reflector 41 away from the double-sided reflector 42. The connecting ring 47 is placed inside the housing 1 and fixedly connected to the housing 1. The connecting ring 47 acts as a connector, and its side... The wall can be provided with screw holes, which are made in the corresponding screw hole positions of the outer shell 1. The connector is fixed to the outer shell 1 by screws, or the connector can be fixed relative to the outer shell 1 by snap-fit ​​or threaded connection, so that the entire beam splitter 4 is stably installed at the end of the outer shell 1. The astigmatism ring 43 includes an astigmatism section 431 and a shielding section 432. The shielding section 432 is placed on one side of the astigmatism ring 43 to block scattered light, preferably on the side corresponding to the face. The astigmatism section 431 is used to transmit light through the astigmatism area 45.

[0034] When the lamp is placed horizontally, the upper part is usually the sky or the direction where no lighting is needed. The shielding section 432 can block the ineffective light rays shining upward, avoid wasting light energy, and reflect this part of the light back to the diffused light area 45, and finally emit it from the diffused light section 431 below, which improves the lighting brightness of the lower and sides, making the use of light energy more efficient, and also avoiding glare to the user when the upper part is lit.

[0035] Specifically, the light-emitting component 3 includes: a movable rod 31, on which multiple auxiliary LED beads 32 are fixedly mounted on its peripheral sidewalls, and an illumination LED bead 33 is fixedly mounted on the side close to the lens 2. The light emitted by the illumination LED bead 33 corresponds to the lens 2. The movable rod 31 is formed by combining multiple PCB boards, for example, by vertically soldering a main PCB board and several sub-PCB boards through pin headers or FPC flexible flat cables to form a polyhedral structure to meet the need to set LED beads with different orientations in different positions. The auxiliary LED beads 32 can switch positions within the focusing area 44 and the diffused area 45.

[0036] It should be noted that the movable rod 31 can be not only spliced ​​from PCB boards, but also a multi-faceted aluminum base with a flexible PCB light board attached to its surface. The diffuser section 431 of the diffuser ring 43 can be made of transparent PC or acrylic material, and its inner or outer surface can be frosted to make the emitted floodlight more uniform and soft.

[0037] In practical applications, the overall operation and working process of the light-emitting adjustment structure of this lighting fixture is as follows: The user operates the focusing component 5, causing the light-emitting component 3 to move back and forth along the outer shell 1. When the lighting beads 33 and some auxiliary beads 32 move into the focusing area 44, the light from these beads is reflected by the double-sided reflector 42 and converged by the lens 2, and then emitted forward to achieve long-distance illumination. When some auxiliary beads 32 move into the diffuser area 45, the light from these beads is reflected repeatedly between the outer surface of the double-sided reflector 42 and the inner surface of the single-sided reflector 41, and finally passes through the diffuser ring 43 to scatter out to the periphery and downwards of the luminaire, achieving floodlight illumination. The two modes can be used individually or combined by lighting beads in different areas.

[0038] More specifically, the focusing assembly 5 includes: a support frame 51, which is fixedly installed inside the housing 1, for example, by means of clips or screws; a support tube 52, which is fixedly connected to the middle of the support frame 51, and has a straight groove 521 extending through the side wall in the middle, the extension direction of which is parallel to the axial direction of the lamp, for providing linear motion guidance; a moving part 53 is slidably connected inside the support tube 52, the moving part 53 is fixedly connected to the side of the moving rod 31 near the support frame 51, the moving part 53 can be a cylindrical slider, the outer wall of which is precisely slidably engaged with the inner wall of the support tube 52 to prevent the moving rod 31 from tilting relative to the support tube 52 and causing jamming during the movement of the moving rod 31; and a detection part 54, which corresponds to the moving part 53 and is fixedly connected to the middle of the support frame 51. The detection unit 54 is used to detect the distance between the moving part 53 and the support frame 51. The detection unit 54 can be an infrared distance sensor or a Hall sensor. If a Hall sensor is used, a magnet needs to be set on the side of the moving frame 53 corresponding to the detection unit 54. If an infrared distance sensor is used, a reflector needs to be installed at the end of the moving frame 53. When the position of the moving part 53 changes, the resistance value or voltage signal of the detection unit 54 changes, thereby sensing the absolute position of the moving rod 31. The rotating sleeve 55 is rotatably sleeved on the outside of the support tube 52, and has an arc-shaped groove 551 that penetrates the side wall in the middle. The arc-shaped groove 551 extends spirally relative to the axis of the rotating sleeve 55. The fixing screw 56 passes through the straight groove 521, the arc-shaped groove 551 and the moving rod 31, and is threadedly connected to the moving rod 31.

[0039] The focusing assembly 5 drives the moving rod 31 to move linearly by rotating the rotating sleeve 55. When the rotating sleeve 55 rotates, the side wall of the arc-shaped groove 551 on it will actuate the fixed screw 56 passing through it. Since the fixed screw 56 also passes through the straight groove 521 on the support tube 52, its rotational freedom is restricted, and it can only move back and forth within the straight groove 521. Therefore, under the actuation of the arc-shaped groove 551, the fixed screw 56, the moving rod 31, and the moving part 53 will slide precisely in a straight line along the axis of the lamp as a whole. By adjusting the rotation angle of the rotating sleeve 55, the distance between the lighting bulb 33 at the front end of the moving rod 31 and the lens 2 can be adjusted steplessly, thereby changing the size of the emitted light spot.

[0040] Specifically, a flip sleeve 57 is fixedly connected to the outer side of the rotating sleeve 55, and an extension rod 58 is slidably connected inside the flip sleeve 57. A support spring 59 is provided inside the flip sleeve 57. One end of the support spring 59 abuts against the bottom of the flip sleeve 57, and the other end abuts against the rear end of the extension rod 58, so that the end of the extension rod 58 always has a tendency to extend outward, so that the end of the extension rod 58 abuts against the inner wall of the outer shell 1. A friction groove 6 is provided on the outer side of the outer shell 1, and a guide groove 7 is provided on the side of the outer shell 1 corresponding to the extension rod 58. An elastic band 510 is provided inside the friction groove 6. The elastic band 510 is, for example, a rubber band, which is tightly fitted in the area of ​​the friction groove 6 of the outer shell 1. The friction band completely covers the guide groove 7 to ensure that the inside of the outer shell 1 is sealed. A pusher 511 is fixedly connected to the inner side of the elastic band 510 and is engaged with the end of the extension rod 58. The pusher 511 can slide along the guide groove 7.

[0041] When focusing is required, simply slide the elastic band 510 on the outer side of the housing 1 circumferentially with your finger. The elastic band 510 causes the pusher 511 on its inner side to slide within the guide groove 7. The pusher 511 then pushes the extension rod 58 and the flip sleeve 57, ultimately causing the rotating sleeve 55 to rotate. The friction between the elastic band 510 and the friction groove 6 ensures that the position of the light-emitting component 3 does not shift when subjected to vibration, thus ensuring the stability and reliability of focusing.

[0042] In summary, during use, by changing the state of the light-emitting component 3, such as lighting up the illumination lamp 33 and some / all of the auxiliary lamp 32, and adjusting the color of the auxiliary lamp 32, the pusher 511 can be slid along the guide groove 7 by manually moving the elastic band 510, which in turn drives the rotating sleeve 55 to rotate relative to the support tube 52. The arc groove 551, in conjunction with the straight groove 521, drives the moving rod 31 to slide relative to the lens 2, thereby changing the size of the light spot emitted from the front section.

[0043] When the moving rod 31 is driven to move backward by the focusing assembly 5, the auxiliary lamp beads 32 welded to the periphery of the moving rod 31 slide from the focusing area 44 through the light-blocking ring 46 into the diffused area 45. At the same time, the detection unit 54 monitors the distance between the moving part 53 and the lens 2 in real time, and controls the main board 12 to turn off the auxiliary lamp beads 32 that have slid out of the diffused area 45 and turn on the auxiliary lamp beads 32 that have slid into the diffused area 45 to avoid wasting light energy.

[0044] When a wide area of ​​front lighting is needed, all the LEDs (including the lighting LEDs 33 and some of the auxiliary LEDs 32) placed in the spotlight area 44 can be lit to increase the luminous flux; when near-peripheral lighting is needed, the auxiliary LEDs 32 located in the diffused light area 45 are lit.

[0045] Example 2 This embodiment also provides a lighting fixture, including: a battery cell 8, which serves as an energy storage component, with a buffer 9 fixedly mounted on its outer side and fixedly installed inside the middle section of the outer casing 1. The buffer 9 can effectively absorb the impact force from drops or collisions, protecting the battery cell 8; a protective plate 10, which is fixedly connected to the end of the buffer 9 near the support frame 51 and snapped into the support frame 51. The protective plate 10 is an insulating plate that physically separates the battery cell 8 from the focusing assembly 5, improving electrical safety; and a sealing member 11, which is fixedly connected to the end of the outer casing 1 away from the beam splitting assembly 4, for... The tail end of the encapsulated shell 1; the control motherboard 12, which is fixedly connected to one side of the enclosure 11 corresponding to the shell 1, the control motherboard 12 is electrically connected to the battery cell 8 and the light-emitting component 3, and is used to control the charging and discharging of the battery cell 8 and the lighting / extinguishing state of the light-emitting component 3. The control motherboard 12 integrates a microcontroller (MCU) and a drive circuit, and is connected to the detection unit 54 and the light-emitting component 3 through the buffer 9 via a flexible flat cable; the charging interface 13 and the switch 14 are both fixedly connected to one side of the control motherboard 12 and are exposed through the enclosure 11 for easy user operation and charging.

[0046] In summary, this lighting fixture can steplessly adjust the size of the forward illumination spot and can combine and switch between two modes: high beam focusing and peripheral floodlighting, to meet a variety of lighting needs.

[0047] Example 3 This embodiment also provides a lighting fixture control method, including the following steps: S1, front lighting, the control board 12 turns on the lighting beads 33, the light is reflected by the double-sided reflector cup 42 to make the focusing area 44 emit light, and the light is focused by the lens 2 to make the light shine forward; S2, peripheral lighting, the main board 12 controls the auxiliary lamp 32 in the diffused section 431 to light up, the light is reflected multiple times by the outer side of the double-sided reflector 42 and the inner side of the single-sided reflector 41 to make the diffused area 45 emit light, the light shines downward and to both sides through the diffused section 431. S3, Spot adjustment: Rotate the elastic band 510 to make the rotating sleeve 55 rotate relative to the support tube 52, adjust the distance of the moving rod 31 relative to the lens 2, and control the spot of the front illumination area. S4, the LED bead is turned off. The detection unit 54 monitors the position of the moving rod 31 relative to the lens 2. Based on this position information, the control board 12 controls the auxiliary LED bead 32 that slides out / into the diffuser zone 45 to turn off / on, realizing the intelligent switching of the LED bead and avoiding unnecessary waste of light energy and power consumption.

[0048] Specifically, it also includes: S31, range control, which controls the main board 12 to light up the corresponding auxiliary lamps 32 in the spotlight area 44, thereby increasing the light intensity in the spotlight area 44 and increasing the illumination range of the front light spot; S32, Warning, the control motherboard 12 adjusts the lighting or flashing state of the auxiliary lamp 32 and the lighting lamp 33 through the program to achieve the warning effect.

[0049] More specifically, it also includes: S321, a color-changing warning light, which controls the motherboard 12 to adjust the color of the auxiliary LED 32 in the diffused light area 45 and change the light color of the diffused light section 431. For example, the auxiliary LED 32 is an RGB three-color LED. By controlling the motherboard 12 to adjust its color, the light color of the diffused light section 431 is changed as an indication or warning of different states. S322, flashing warning, controls the auxiliary LED 32 and the lighting LED 33 to flash alternately at different frequencies and rhythms, to achieve richer and more recognizable flashing warning modes.
