For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.
[0032] The present utility model provides a tunnel lamp with a safety protection device.
[0033] In the embodiments of the present utility model, as Figures 1 to 4 shown, a tunnel lamp 10 with a safety protection device is provided, which includes a heat dissipation component 100, a lamp board component 200, a heat-conducting insulating member 300, an insulating positioning component 400, and a light-transmitting cover 500. The lamp board is installed on one side of the heat dissipation component 100, and at least one positioning connection portion is provided on the outer peripheral edge of the lamp board; the heat-conducting insulating member 300 is installed between the heat dissipation component 100 and the lamp board component 200; the insulating positioning component 400 cooperates with the positioning connection portion to position and connect the lamp board component 200 to the heat dissipation component 100; the light-transmitting cover 500 is fixedly connected to the heat dissipation component 100, and the light-transmitting cover 500 covers the upper part of the lamp board component 200 to press and connect the lamp board component 200 and the heat-conducting insulating member 300 to the heat dissipation component 100.
[0034] The heat dissipation component 100 is mainly used to dissipate heat for the tunnel light. Since the LED light source generates heat during operation, if the heat cannot be dissipated in time, it will cause the temperature of the LED light source to rise, thereby affecting its luminous efficiency and lifespan. The heat dissipation component 100 effectively conducts the heat to the air through its large-area heat dissipation surface and optimized heat dissipation structure, ensuring that the internal temperature of the tunnel light remains within an appropriate range, thus guaranteeing the stable operation and long lifespan of the LED light source.
[0035] The lamp board component 200 is the part of the tunnel light that realizes the lighting function. The lamp board component 200 integrates the LED light source and related circuits, converting electrical energy into light energy. In some embodiments, the lamp board component 200 consists of an aluminum substrate with a printed circuit, LED light sources mounted by SMT (Surface Mounted Technology), and DOB (Driver-On-Board) components for driving the light sources. When the tunnel light is operating normally, the 380V voltage line introduced from the outside is connected to the lamp board component 200.
[0036] The heat-conducting and insulating component 300, as a medium for heat conduction, efficiently transfers the heat generated by the lamp board component 200 to the heat dissipation component 100 to ensure that the heat is dissipated in time. This helps to reduce the temperature of the LED light source and improve its operating stability and lifespan. Secondly, the heat-conducting and insulating component 300 also serves as an electrical isolation layer, preventing current leakage caused by the damage of the circuit insulation layer of the lamp board component 200. It prevents the current from directly conducting from the lamp board component 200 to the heat dissipation component 100 or other metal parts, thereby improving the electrical safety of the tunnel light.
[0037] The insulating positioning component 400, firstly, cooperates with the positioning connection part on the lamp board component 200 to accurately position the lamp board component 200 on the heat dissipation component 100, ensuring a tight fit and stable connection between the lamp board component 200 and the heat dissipation component 100. This helps to improve the heat dissipation performance and the reliability of the electrical connection of the tunnel light. Secondly, the insulating positioning component 400 itself has insulating properties, which can further prevent short circuits and current leakage between electrical components, increasing the electrical safety of the tunnel light.
[0038] The light-transmitting cover 500 is a component in the tunnel light that is used to protect the lamp board component 200 and provide light output. The light-transmitting cover 500, as a protective cover, prevents dust, moisture, foreign objects, etc. in the external environment from damaging the lamp board component 200 and protects the integrity of the internal structure of the tunnel light. Secondly, the light-transmitting cover 500 presses the lamp board component 200 and the heat-conducting and insulating component 300 tightly on the heat dissipation component 100 through its fixed connection method, ensuring a tight fit and stable connection between them. This helps to improve the heat dissipation performance and the reliability of the electrical connection of the tunnel light.
[0039] The lamp board assembly 200 of the present application realizes the installation positioning and insulation on the heat dissipation assembly 100 through the positioning connection part, and a heat-conducting and insulating part 300 is also arranged between the lamp board assembly 200 and the heat dissipation assembly 100 to realize the insulation between the lamp board assembly 200 and the heat dissipation assembly 100. The fixation between the lamp board assembly 200 and the heat dissipation assembly 100 is achieved by the transparent cover 500 applying a positive pressure towards the heat dissipation assembly 100 to press and connect the lamp board assembly 200, thereby realizing multi-layer electrical protection for the tunnel lamp, preventing the circuit insulation layer of the lamp board assembly 200 from being directly introduced into the heat dissipation assembly 100 due to accidental damage, causing potential safety hazards, effectively improving the electrical safety of the tunnel lamp during use, and preventing accidental electric leakage of the tunnel lamp during use. At the same time, the pressing force of the transparent cover 500 makes the lamp board assembly 200 and the heat-conducting and insulating part 300 closely fit on the surface of the heat dissipation assembly 100, ensuring that the heat on the lamp board assembly 200 is transferred to the heat dissipation assembly 100 for heat dissipation.
[0040] Referring to Figure 2 and Figure 4 According to a tunnel lamp 10 with a safety protection device provided by the present utility model, a cavity 510 is formed by the depression on the side of the transparent cover 500 facing the heat dissipation assembly 100, and the lamp board assembly 200 and the heat-conducting and insulating part 300 are arranged in the cavity 510.
[0041] It can be understood that the cavity 510 formed by the depression of the transparent cover 500 provides a compact installation space for the lamp board assembly 200 and the heat-conducting and insulating part 300. It helps to reduce the overall volume of the tunnel lamp and makes it more suitable for installation in a limited space. The cavity 510 design of the transparent cover 500 provides a relatively enclosed space for accommodating the lamp board assembly 200 and the heat-conducting and insulating part 300. It can prevent dust, moisture, foreign objects, etc. in the external environment from directly contacting the lamp board assembly 200 and the heat-conducting and insulating part 300, thereby improving the electrical safety of the tunnel lamp and reducing the safety risks caused by short circuits or overheating.
[0042] By arranging the lamp board assembly 200 and the heat-conducting and insulating part 300 in the cavity 510 of the transparent cover 500 and using the fixed connection method of the transparent cover 500 to press them on the heat dissipation assembly 100, it can ensure the close fit and stable connection between these components. It increases the effective contact area between the lamp board assembly 200 and the heat-conducting and insulating part 300 and improves the heat dissipation efficiency.
[0043] Furthermore, the total thickness of the lamp board assembly 200 and the heat-conducting and insulating part 300 coincides with the height of the cavity 510.
[0044] It is understandable that the total thickness of the lamp board assembly 200 and the heat-conducting insulating member 300 matches the height of the inner cavity 510, ensuring the stable position of the lamp board assembly 200 and the heat-conducting insulating member 300 inside the tunnel lamp. And it can prevent the lamp board assembly 200 from being crushed, improving the assembly reliability of the tunnel lamp. At the same time, since the lamp board assembly 200 and the heat-conducting insulating member 300 match the height of the inner cavity 510, the contact area between them is maximized. This helps the heat to be more effectively transferred from the lamp board assembly 200 to the heat dissipation assembly 100 through the heat-conducting insulating member 300, thereby improving the heat dissipation performance. It avoids the problems of heat accumulation and poor heat dissipation caused by poor contact or excessive gaps.
[0045] Referring to Figure 2 and Figure 4 According to a tunnel lamp 10 with a safety protection device provided by the present utility model, the light-transmitting cover 500 includes a plurality of lenses 520 and a pressing strip 530. The lenses 520 are correspondingly arranged with the light sources on the lamp board assembly 200. A pressing strip 530 is provided between adjacent lenses 520. The pressing strip 530 abuts against the outer peripheral side of the light source to press the lamp board assembly 200 tightly against the heat dissipation assembly 100.
[0046] It is understandable that each lens 520 corresponds to each light source on the lamp board assembly 200 to ensure that the light emitted by each light source can be focused or scattered through the lens 520 to achieve the desired lighting effect. The pressing strip 530 is arranged between adjacent lenses 520 and abuts against the outer peripheral side of the light source. To ensure the close contact between the lens 520 and the lamp board assembly 200 and prevent them from shifting due to vibration or external force. At the same time, the pressing strip 530 also presses the lamp board assembly 200 tightly against the heat dissipation assembly 100. It helps to enhance the heat conduction efficiency between the lamp board assembly 200 and the heat dissipation assembly 100, ensuring that the heat generated by the light source can be transferred in a timely and effective manner.
[0047] Referring to Figure 2 and Figure 3 According to a tunnel lamp 10 with a safety protection device provided by the present utility model, a positioning groove 210 is provided on the positioning and connecting part. The insulating positioning assembly 400 includes an insulating gasket 410 and a fastener 420. The insulating gasket 410 is fixedly connected to the heat dissipation assembly 100 through fastening. The insulating gasket 410 cooperates with the positioning groove 210 to position the lamp board assembly 200.
[0048] It can be understood that the number of positioning and connecting parts on the lamp board assembly 200 can be adjusted according to the size of the lamp board tunnel lamp or other design requirements. In this embodiment, one positioning and connecting part is provided on each of the opposite sides of the lamp board assembly 200 for illustration, and other embodiments can be implemented with reference to this embodiment. Since the lamp board assembly 200 cannot be positioned and fixed by screws or the like, during assembly, it is necessary to rely on the cooperation of the insulating gasket 410, the fastener 420, and the holes on the radiator for fixation. Positioning grooves 210 are reserved on both sides of the lamp board assembly 200, and effective positioning is achieved by the insulating gasket 410 being tangentially attached to the grooves.
[0049] Optionally, the shape of the positioning groove 210 can be set as required, and can be circular, semi-circular, irregular, etc., and no special limitation is made here.
[0050] Referring to Figure 2 and Figure 3 , for a tunnel lamp 10 with a safety protection device provided according to the present utility model, the outer radius of the insulating gasket 410 is at least 2 mm larger than the maximum radius of the fastener 420.
[0051] It can be understood that the main function of the insulating gasket 410 is to provide electrical isolation and prevent current from passing through an unexpected path. In this embodiment, by designing the outer radius of the insulating gasket 410 to be at least 2 mm larger than the maximum radius of the fastener 420, a wider insulating area can be ensured around the fastener 420. Effectively ensuring the creepage distance between the fastener 420 and the lamp board assembly 200, thereby avoiding potential safety hazards such as electrical short circuits or electric shocks.
[0052] Referring to Figure 2 and Figure 3 , for a tunnel lamp 10 with a safety protection device provided according to the present utility model, the outer edge of the heat-conducting and insulating member 300 is at least 2 mm larger than the outer edge of the lamp board assembly 200. And the thickness of the heat-conducting and insulating member 300 is greater than or equal to 1 mm.
[0053] It can be understood that the outer edge of the heat-conducting and insulating member 300 is at least 2 mm larger than the outer edge of the lamp board assembly 200, ensuring that the heat-conducting and insulating member 300 can completely cover the edge of the lamp board assembly 200, thereby effectively preventing leakage current from being transmitted from the lamp board cut surface to the radiator or other metal components. The thickness of the heat-conducting and insulating member 300 is greater than or equal to 1 mm. The sufficient thickness ensures that the heat-conducting and insulating member 300 has sufficient insulating performance to effectively block the transmission of current and improve the safety of the tunnel lamp.
[0054] Referring to Figure 2 , for a tunnel lamp 10 with a safety protection device provided according to the present utility model, it further includes a sealing ring 600, and the sealing ring 600 is disposed around between the light-transmitting cover 500 and the heat dissipation assembly 100.
[0055] It can be understood that the sealing ring 600 is disposed around the light-transmitting cover 500 and the heat dissipation component 100 to improve the sealing performance of the inner cavity 510 of the light-transmitting cover 500, preventing moisture or dust in the external environment from entering the inner cavity 510 and causing short circuits, etc. Thus, it protects the internal electrical components, mechanical parts, etc. from being damaged by liquids, avoiding potential safety hazards such as equipment damage or electrical short circuits that may be caused thereby.
[0056] Referring to Figure 2 and Figure 3 , according to a tunnel lamp 10 with a safety protection device provided by the present utility model, the tunnel lamp 10 with a safety protection device further includes an installation component 700. The installation component 700 includes an installation bracket 710 and a connection plate 720. The installation bracket 710 is fixedly connected to the heat dissipation component 100 through the connection plate 720.
[0057] It can be understood that the installation bracket 710 is suitable for connecting to the inner wall of the tunnel or other fixed positions. The connection plate 720 is suitable for connecting and fixing the components installed on the heat dissipation component 100 to the installation bracket 710, ensuring a tight fit and a firm connection between the two. Finally, by adjusting the angle and position of the installation bracket 710, the lamp is adjusted to a suitable lighting angle and position.
