[0028] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0029] In broadcasting, video production, live performances, and various multimedia content production fields, Tally lights play a crucial role as an important signaling device. They are primarily used to visually indicate the operational status of equipment, such as whether a camera is recording or broadcasting live, ensuring efficient collaboration among staff and preventing operational errors or content production accidents. A Tally light system consists of three parts: the Tally light head, the control interface and drive circuit, and the signal transmission system. These three parts are installed in a housing and work together. Existing Tally light housings typically consist of two separate parts, connected and fixed together with screws. However, this method is not only cumbersome to install, but the exposed screws also affect the aesthetics of the overall structure. More importantly, the exposed screws are prone to rust and corrosion, affecting the lifespan of the Tally light.

[0030] Based on this, this application provides a small signal light.

[0031] Example

[0032] See Figures 1-5 This embodiment provides a small signal light, including a main body 1. The main body 1 includes an integrally formed first shell 11 and a second shell 12. The top of the first shell 11 is provided with an opening, and the bottom and side walls are designed as an integral piece.

[0033] The edge of the opening is provided with a snap-fit ​​element 115, and the second housing 12 is snapped into the snap-fit ​​element 115.

[0034] Specifically, in practical applications, the first housing 11 is integrally molded using injection molding, ensuring that its bottom and sidewalls form a single structure with good structural strength. A ring-shaped locking block 115 is formed by injection molding at the opening edge of the top of the first housing 11. Similarly, the second housing 12 is produced using injection molding, with a matching slot formed at its edge corresponding to the ring-shaped locking block of the first housing 11. Simultaneously, the outer surfaces of both the first and second housings 12 are spray-coated with a uniform polyurethane wear-resistant coating. During assembly, the circuit board, light source, and other components of the signal light are installed inside the first housing 11. The signal light's indicating function is achieved through a pre-reserved light-transmitting area on the second housing 12 (which can be designed in different shapes, such as circular or square, to transmit the light signal).

[0035] In the aforementioned small traffic light assembly, the second housing 12 is aligned with the snap-fit ​​member 115 of the first housing 11, and appropriate pressure is applied to complete the snap-fit ​​assembly of the second housing 12 and the first housing 11, forming a complete traffic light body 1. At this time, the integrated bottom and sidewalls of the first housing 11 provide stable housing space for internal components, and the snap-fit ​​structure ensures a tight connection between the housings without obvious gaps. This small traffic light reduces the number of parts through the one-piece molded first housing 11, and the snap-fit ​​member 115 allows the second housing 12 to be quickly and accurately assembled with the first housing 11 without the need for complex tools and tedious alignment operations. Compared to traditional multi-part assembled traffic lights, this effectively shortens installation time. Furthermore, there are no exposed screws on the first housing 11 or its outer wall, which not only gives the entire light a high degree of visual neatness and aesthetics but also reduces the risk of screw rust and corrosion, thereby improving the overall lifespan of the light.

[0036] More specifically, a mounting base plate 4 is provided at the opening, the mounting base plate 4 is fixedly connected to the first housing 11, and the mounting base plate 4 is adapted to the inner wall of the first housing 11 at the opening.

[0037] Furthermore, the mounting base plate 4 is provided with mounting screw holes, and a lamp plate 3 is provided on one side of the mounting base plate 4. The lamp plate 3 is fixedly connected to the mounting screw holes by screws.

[0038] The second housing 12 completely covers the lamp panel 3, and the second housing 12 is made of transparent material.

[0039] Furthermore, a gap is provided between the edge of the lamp plate 3 and the inner wall of the first housing 11, and the lamp plate 3 protrudes outward from one side of the mounting base plate 4, so that a groove 114 is formed between the edge of the lamp plate 3 and the inner wall of the first housing 11.

[0040] One end of the second housing 12 is inserted into the clamping groove 114.

[0041] Specifically, after the first housing 11 is injection molded, a mounting base plate 4 (the base plate material can be aluminum alloy, which combines heat dissipation and structural strength) that is adapted to the inner wall of the first housing 11 is installed at the opening using screws or pre-embedded nuts. The base plate has pre-machined mounting screw holes. The lamp plate 3 is then fixed to the mounting base plate 4 using screws. At this point, the edge of the lamp plate 3 forms a groove 114 with the inner wall of the first housing 11, and the lamp plate 3 protrudes outward from the base plate, ensuring space for the subsequent insertion of the second housing 12. The power supply and control circuits of the lamp plate 3 are connected, and the LED lighting status is tested to verify the light transmission effect and housing sealing performance of the second housing 12, ensuring that the signal light can stably perform its status indication function. For example, when used as a Tall y light, it can clearly respond to camera working status switching, accurately turning on / off or changing color. Then, one end of the second housing 12 is precisely inserted into the slot, utilizing the moderate elasticity of the PC material to fit the slot and achieve a tight connection, completing the assembly of the signal light body 1.

[0042] The first housing 11 is integrally molded to eliminate gaps in the side wall splicing, and the second housing 12 is tightly inserted into the slot. Combined with the covering of the openings on the mounting base plate 4, a "fully enclosed" sealed structure is formed. This improves the dust and water resistance of the signal light, effectively resisting dust and moisture corrosion in studios and industrial sites, and reducing the risk of internal circuit short circuits and damage.

[0043] In a specific embodiment, multiple snap-fit ​​members 115 are evenly arranged on the inner wall of the first housing 11 along the circumference of the first housing 11.

[0044] The snap-fit ​​member 115 protrudes from the inner wall of the first housing 11 toward the center, and the protrusion height of the snap-fit ​​member 115 gradually increases along the direction from the top to the bottom of the first housing 11.

[0045] The circumferentially distributed snap-fit ​​components 115 disperse the connection force between the second housing 12 and the first housing 11 to multiple contact points. Compared to a single snap-fit ​​structure, this avoids housing deformation and breakage caused by localized stress concentration. When the signal light is subjected to vibration, the multi-point force can disperse the impact, maintain the stability of the connection structure, and reduce the risk of loosening or detachment. The "smaller at the top and larger at the bottom" design of the protrusion, after assembly, allows the snap-fit ​​components 115 to form a "barbed" restraint on the second housing 12, improving connection reliability.

[0046] Furthermore, a control motherboard is provided in the first housing 11, and a rotary switch is provided on the control motherboard;

[0047] The first housing 11 is provided with a mounting groove 111, and a control knob 112 is provided in the mounting groove 111. The control knob 112 is fixedly connected to the rotary switch.

[0048] The integrated design of the control knob 112 and rotary switch eliminates the need for additional equipment compared to traditional "external controller adjustment" or "button switching." Multiple modes can be quickly switched directly by rotating the knob (e.g., temporarily switching between "record / standby" states for the studio Tall y lights). The multi-position rotary switch can preset various working modes (e.g., 3-5 positions), and in conjunction with the signal processing of the control motherboard, it can accurately correspond to the brightness, flashing frequency, and color switching functions of the indicator lights, making it convenient to use.

[0049] Furthermore, a storage battery is also provided in the first housing 11, and a charging interface 113 is provided in the first housing 11. The storage battery is electrically connected to the control motherboard, and the charging interface 113 is electrically connected to the storage battery.

[0050] The combination of the battery and the charging interface 113 enables a dual-mode system of "wired power supply (working simultaneously while charging) + wireless power supply (working independently after power failure)," overcoming the limitation of traditional traffic lights relying on a fixed power source.

[0051] Furthermore, a clamping member 2 is provided on the outer wall of the first housing 11. The clamping member 2 is hinged to the outer wall of the first housing 11 via a connecting shaft 21. A torsion spring 22 is provided on the connecting shaft 21.

[0052] Furthermore, a pressure post 23 is provided on the side of the clamping member 2 near the outer wall of the first housing 11, and a pressure groove 24 corresponding to the pressure post 23 is provided on the outer wall of the first housing 11.

[0053] The clamping member 2 is hinged to the first housing 11 via the connecting shaft 21. Combined with the elastic restoring force of the torsion spring 22, it enables an "opening and closing" clamping mechanism, making the installation of the signal light more convenient. The pressure post 23 on the inner side of the clamping member 2 forms a "concave-convex fit" with the pressure groove 24 on the outer wall of the first housing 11. When the clamping member 2 is closed, the pressure post 23 is embedded in the pressure groove 24. This restricts the lateral displacement of the clamping member 2, preventing it from shifting due to slight shaking of the carrier. Furthermore, the contact point between the pressure post 23 and the pressure groove 24 increases friction, which, combined with the clamping force of the torsion spring 22, forms a double fixation. Even in tilted installation scenarios, the signal light remains stable and will not slide down due to gravity.
