Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to warning lights. Background Technology

[0002] Warning lights are lighting devices used for alerting, indicating, or warning purposes, and are widely used in vehicles, machinery, construction sites, security systems, and other applications. Warning lights use flashing, color changes, or brightness variations to indicate specific states or dangers, attracting the attention of nearby people or other road users, thereby achieving the purpose of early warning and safety protection. For example, vehicle warning lights are installed on the roof or rear of vehicles to indicate the operation or driving status of police cars, fire trucks, construction vehicles, etc.; machinery warning lights are used on industrial equipment to display the operating, malfunction, or standby status of the equipment; construction site warning lights are used on construction sites to indicate dangerous areas or nighttime construction; and so on.

[0003] However, most current warning lights have complex structures and are fixed in a fixed position using a fixed connection method, which cannot flexibly change the position as needed. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, this utility model provides a track beam support, which has a simple structure, is easy to use, and can be flexibly installed in different positions as needed.

[0005] The technical solution adopted in this utility model is to design a warning light, including a lamp body, which is a cylindrical shell. A ring of light-emitting elements is arranged at the top inside the shell. A cylindrical reflector cup is arranged inside the shell below the light-emitting elements. The reflective cross-sectional profile of the reflector cup is semi-parabolic, and the light-emitting elements are located at the focal point of the parabola. The portion of the shell corresponding to the emitted light from the reflector cup is made of a light-transmitting material. A circuit board is arranged at the upper end of the shell. The upper port of the cylindrical reflector cup is connected to the circuit board. A rechargeable battery module that powers the circuit board is arranged between the inner side of the cylindrical reflector cup and the shell. A charging port connecting the rechargeable battery module to an external charging cable is provided on the side wall of the shell. A magnet is arranged at the bottom of the shell, allowing the shell to be magnetically attracted and fixed to a ferromagnetic object.

[0006] In some embodiments, the light-emitting element is a ring of LEDs on the circuit board, and a control switch electrically connected to the circuit board is located at the center of the upper end of the housing.

[0007] In some embodiments, the outer casing includes an upper casing, a lower casing, and a cylindrical light-transmitting cover connected between the upper casing and the lower casing. The lower casing has a groove along its rim, and the lower opening of the light-transmitting cover is axially engaged in the groove. The lower port of the reflector is supported on the rim of the lower casing located inside the light-transmitting cover. The upper casing has a limiting part that axially limits the movement of the circuit board. The limiting part has a positioning hole that connects the circuit board to the outside. One port of the positioning hole is connected to the circuit board, and the other port is sealed with an elastic membrane. The control switch is located in the positioning hole, and the pressing part of the control switch corresponds to the elastic membrane.

[0008] In some embodiments, the bottom of the outer casing is connected to a cylindrical support column, which is divided into two columns by a cut at a 45-degree angle to its axis. The cut sections of the two columns are both elliptical, and the cut sections of the two columns are connected by a rotating assembly that controls the two columns to rotate about an axis perpendicular to the cut sections.

[0009] In some embodiments, the rotating component is a motor, the stator of which is fixedly connected to a column, and the rotor of which is fixedly connected to another column.

[0010] In some embodiments, the two columns are a first column and a second column, the second column is connected to the bottom end of the lamp housing, the motor body is fixed on the first column, the motor shaft is connected to the second column, and a battery is provided on the first column to provide power to the motor.

[0011] In some embodiments, a magnet is provided at the end of the first column, so that the support column can be attracted and fixed to a ferromagnetic material object by the magnetic force of the magnet.

[0012] In some implementations, the cut sections of the two columns are electrically connected by a conductive slip ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model of vehicle warning light significantly improves the overall performance of lighting and use through structural innovation and optical optimization. The light-emitting element is located at the focal point of a semi-parabolic reflector cup. Combined with the top-larger, bottom-smaller conical reflector cup design, it can effectively and evenly reflect LED light to all directions, achieving a high-brightness, wide-angle ring-shaped light emission effect, significantly improving warning visibility and safety. The reflector cup and circuit board are fixed with screws, and a rechargeable battery module is built inside. The structure is compact, the power supply is independent, and it is convenient for charging. The double magnet structure at the bottom allows for quick adsorption installation and can be flexibly fixed to any ferromagnetic surface of the vehicle, improving the flexibility of placement.

[0014] By incorporating a motor drive through a rotatable support column structure, the lamp body can switch between coaxial and vertical directions, enabling intelligent adjustment of the illumination angle to adapt to different working conditions and lighting needs. Attached Figure Description

[0023] The following are specific embodiments of this utility model, and the technical solution of this utility model will be further described with reference to the accompanying drawings. However, this utility model is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of features described in the embodiments are not necessarily necessary for the solution of the utility model.

[0024] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0025] like Figure 1 , 2 As shown in Figures 3 and 4, the warning light includes a lamp body, which is a cylindrical outer shell. A ring of light-emitting elements is disposed at the top of the outer shell. The light-emitting elements are arranged in a ring of LED lights 2 on a circuit board 1. A cylindrical reflector 3, a conical cylinder larger at the top and smaller at the bottom, is disposed inside the outer shell below the light-emitting elements. The reflective cross-section of the reflector 3 is semi-parabolic, with the light-emitting elements located at the focal point of the parabola, thus reflecting the light emitted by the LED lights 2 outwards. The portion of the outer shell corresponding to the emitted light from the reflector 3 is made of a light-transmitting material, such as transparent plastic, to allow light to pass through. A circular circuit board 1 is disposed at the upper end of the outer shell, and the upper port of the cylindrical reflector 3 is connected to the circuit board 1. A rechargeable battery module 16, which supplies power to the circuit board 1, is disposed between the inner side of the cylindrical reflector 3 and the outer shell, and is fixed by screws. That is, the rechargeable battery module 16 is disposed in the cavity between the reflector 3 and the lamp body outer shell below it. The rechargeable battery module 16 is electrically connected to the circuit board 1 to supply power to the LED lamp 2. The side wall of the outer shell is provided with a charging socket 17 for connecting the rechargeable battery module 16 to an external charging cable. Two parallel magnets 13 are provided at the bottom of the outer shell. The magnets 13 enable the outer shell to be attracted and fixed to a ferromagnetic material object by the magnetic force of the magnets 13. For example, the lamp body can be attracted and fixed to any position on the vehicle shell as needed by using the attraction force of the magnets 13.

[0026] A control switch 4, which is electrically connected to the circuit board 1, is provided at the center of the upper part of the outer casing. Pressing the control switch 4 controls the operation of the LED light 2.

[0027] The outer shell includes an upper shell 5, a lower shell 6, and a cylindrical light-transmitting cover 7 connecting the upper shell 5 and the lower shell 6. The three parts can be connected together by snap-fit, threaded connection, or adhesive bonding. The lower shell 6 has a groove 8 around its opening, and the lower opening of the light-transmitting cover 7 is axially engaged in the groove 8. The lower port of the reflector cup 3 is supported on the opening of the lower shell 6 located inside the light-transmitting cover 7. The upper shell 5 has a limiting part that axially limits the movement of the circuit board 1. The limiting part has a positioning hole that connects the circuit board 1 to the outside. One port of the positioning hole is connected to the circuit board 1, and the other port is sealed with an elastic membrane 18. The control switch 4 is located in the positioning hole, and the pressing part of the control switch 4 corresponds to the elastic membrane 18. In this embodiment, the limiting part is a tube 9 extending from the upper housing 5 toward the circuit board 1. The cavity of the tube 9 is the positioning hole. The circuit board 1 is supported between the tube 9 and the reflector 3, thereby making the circuit board 1 and the reflector 3 stably fixed relative to the outer shell. Example 2

[0028] like Figure 5 , 6 As shown in Figure 7, the bottom of the outer casing is connected to a cylindrical support column. The support column is divided into two columns by a cut 10 at a 45-degree angle to its axis, so that the cross-section of the cut 10 of both columns is elliptical. The cross-sections of the cut 10 of the two columns are connected by a rotating assembly, which controls the two columns to rotate about an axis perpendicular to the cross-section of the cut 10. In this embodiment, the rotating assembly is a motor 14. The stator of the motor 14 is fixedly connected to one column, and the rotor of the motor 14 is fixedly connected to the other column.

[0029] The support column is divided into two columns, namely the first column 11 and the second column 12. The second column 12 is connected to the bottom end of the lamp housing. The motor body 14 is fixed on the first column 11, and the rotating shaft of the motor 14 is connected to the second column 12. A magnet 13 is provided at the end of the first column 11, so that the support column can be attracted and fixed to a ferromagnetic material object by the magnetic force of the magnet 13. That is, the magnet 13 on the bottom of the lamp housing can be set on the support column.

[0030] When the motor 14 causes the first column 11 and the second column 12 to rotate 180 degrees relative to each other, the rotation axes of the first column 11 and the second column 12 can switch between being coaxial and perpendicular to each other, thereby making the first column 11 collinear or perpendicular to the second column 12, thus changing the position or orientation of the lamp body to adapt to different lighting or warning needs.

[0031] A battery that provides power to the motor 14 can be installed on the first column 11. The cut sections 10 of the two columns are electrically connected by a conductive slip ring 15, which enables electrical connection between relatively rotating objects. That is, a battery can be omitted from the lamp body; instead, the rechargeable battery module 16, which was originally installed in the lamp body, can be installed inside the first column 11, and the rechargeable battery module 16 inside the first column 11 is electrically connected to the circuit board 1 inside the lamp body via the conductive slip ring 15.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0033] Although this document uses a number of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention. The order of actions, steps, etc., in the apparatus and methods shown in the specification and drawings can be implemented in any order unless a specific order is explicitly specified, and as long as the output of a preceding process is not used in a subsequent process. Similar sequential terms used for descriptive convenience (e.g., "firstly," "next," "secondly," "again," "then," etc.) do not imply that the actions must be performed in such an order.

[0034] Those skilled in the art will understand that all directional references (e.g., above, below, up, up, down, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to aid the reader's understanding and do not imply (e.g., a limitation on the scope of the invention as defined by the appended claims) a limitation on the scope of the invention as defined by the appended claims. They are merely for the purpose of facilitating the description of the application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation. The directional terms "inside" and "outside" refer to inside or outside relative to the outline of the respective components themselves.

[0035] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0036] Additionally, some vague terms (e.g., substantially, certain, generally, etc.) may refer to slight inaccuracies or minor deviations in conditions, quantities, values, or dimensions, some of which are within manufacturing tolerances or limits. It should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components; unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.
