[0027] This utility model proposes an LED lamp 100.

[0028] Please see Figure 1In one embodiment of this utility model, the LED lamp 100 includes: a housing 1, a first circuit board 2, a second circuit board 3, and a cover 4. A mounting groove 1a is formed inside the housing 1. The first circuit board 2 is provided with a first light-emitting element 21, and is connected to the housing 1. The first circuit board 2 is located within the mounting groove 1a, and the first light-emitting element 21 is located on the side of the first circuit board 2 facing away from the bottom of the mounting groove 1a. The second circuit board 3 is provided with a second light-emitting element 31, and is connected to the housing 1. The second circuit board 3 is located within the mounting groove 1a, and the second light-emitting element 31 is located on the side of the second circuit board 3 facing away from the first circuit board 2. The second circuit board 3 is electrically connected to the first circuit board 2. The second circuit board 3 has a light opening 3a, and the second light-emitting element 31 is located around the periphery of the light opening 3a. The orthogonal projection of the first light-emitting element 21 onto the second light-emitting element 31 is located within the light opening 3a. The cover 4 is detachably connected to the housing 1, and is located at the opening of the mounting groove 1a. The cover 4 has a light outlet 4a, which is used to emit light from the first light-emitting element 21 and the second light-emitting element 31.

[0029] In this embodiment, the housing 1 is designed as a container with a specific shape, and a mounting groove 1a is formed inside it for fixing and supporting the circuit board. The first circuit board 2 is fixed inside the housing 1 and located within the mounting groove 1a. One or more LEDs are mounted on the first circuit board 2 as first light-emitting elements 21. These LEDs are arranged on one side of the first circuit board 2, i.e., the side facing away from the bottom of the mounting groove 1a. This design allows the first light-emitting elements 21 to effectively guide the light in the desired direction. The main advantages of this design are its compact structure and ease of installation. By integrating the first circuit board 2 and the first light-emitting elements 21 within the mounting groove 1a of the housing 1, space can be saved and the assembly process of the lamp can be simplified. In addition, this layout allows the light from the first light-emitting elements 21 to be emitted directly from the front of the lamp, improving the light utilization efficiency and the lighting effect of the lamp. At the same time, since the first light-emitting elements 21 are located on one side of the circuit board, this design also helps with heat dissipation and extends the lifespan of the LEDs.

[0030] It should be noted that the second circuit board 3 is also placed in the mounting slot 1a of the housing 1 and connected to the housing 1. Unlike the first circuit board 2, one side of the second circuit board 3 faces away from the first circuit board 2, and second light-emitting elements 31 are arranged on it. These light-emitting elements are evenly arranged along the edge of the specially designed light opening 3a on the second circuit board 3. This layout allows the light from the first light-emitting element 21 to have its orthographic projection completely fall within the light opening 3a on the second circuit board 3 when it passes through the second light-emitting element 31, thereby achieving the composite and directional output of the light from the first light-emitting element 21 and the second light-emitting element 31. The main advantage of this design is that it can achieve the composite and directional output of light, improving the uniformity and directionality of the lighting effect. By arranging the second light-emitting element 31 around the periphery of the light opening 3a, a soft diffusion effect can be formed when the light passes through the opening, reducing direct glare and improving visual comfort. At the same time, the light from the first light-emitting element 21 falling into the light opening 3a through the orthographic projection of the second light-emitting element 31 can achieve more complex lighting effects, such as halos and gradients, enhancing the aesthetics and functionality of the lamp. Furthermore, the electrical connection design allows the two circuit boards to work together, enabling more flexible light control and adjustment to meet lighting needs in different scenarios. This structural design also helps improve the overall stability and durability of the luminaire, as the circuit boards are fixed within the mounting slot 1a, reducing the impact of vibration and shock on the circuit boards.

[0031] In one embodiment, the cover 4 and the housing 1 are detachably connected by snaps or bolts, facilitating installation and maintenance. The cover 4 is located at the opening of the mounting groove 1a, and has a light outlet 4a, which is a key part for light emission. This design allows the light from the first light-emitting element 21 and the second light-emitting element 31 to be combined and emitted through the light outlet 4a on the cover 4, thereby realizing the lighting function of the lamp. Due to the detachable connection between the cover 4 and the housing 1, the maintenance and replacement of the lamp becomes more convenient and quick, reducing maintenance costs and time. The light outlet 4a on the cover 4 effectively controls the direction of light emission, improving lighting efficiency and reducing light pollution. The cover 4 being located at the opening of the mounting groove 1a makes the entire lamp structure more compact, saving space and adapting to more installation environments.

[0032] The technical solution of this utility model involves designing an LED lamp 100, which includes a housing 1 with a mounting groove 1a inside. A first circuit board 2 and a second circuit board 3 are mounted inside the housing 1. A first light-emitting element 21 is mounted on the first circuit board 2, located within the mounting groove 1a and facing away from the bottom of the groove; a second light-emitting element 31 is mounted on the second circuit board 3, also located within the mounting groove 1a but facing away from the first circuit board 2. The two circuit boards are electrically connected. The second circuit board 3 has a light opening 3a around which the second light-emitting element 31 is arranged, and the orthographic projection of the first light-emitting element 21 is located within this opening. The lamp also includes a removable cover 4 located at the opening of the mounting groove 1a, with a light outlet 4a, allowing light from the first and second light-emitting elements 31 to be emitted. The main advantages of this design are its compact structure and flexible light control. By arranging the two light-emitting elements on two separate circuit boards and having their light emitted through a common outlet, more complex light distributions and effects can be achieved while maintaining the lamp's compact size. The light from the first light-emitting element 21 can serve as primary illumination, while the light from the second light-emitting element 31 can be used for auxiliary lighting or to create specific lighting effects, such as edge lighting or background lighting. The background light provided by the second light-emitting element 31 can be customized according to customer needs, offering options such as monochrome, dual-color, or RGB lighting, with effects including flashing, flowing water, and marquee effects. This design not only enhances the aesthetics of the luminaire but also strengthens its functionality, enabling it to adapt to different lighting needs and vehicle exterior designs. Furthermore, the removable cover 4 facilitates maintenance and replacement, further improving the practicality and economy of the luminaire.

[0033] In one embodiment of this utility model, please refer to Figure 1 The LED lamp 100 includes a light cup 5, one end of which is connected to the second circuit board 3, and the other end of which is connected to the housing 1. A light channel 5a is formed inside the light cup 5, and the first light-emitting element 21 is located at the end of the light channel 5a near the first circuit board 2.

[0034] In one embodiment, one end of the light cup 5 is connected to the second circuit board 3 via bolts or clips, while the other end is connected to the housing 1 via bolts or clips. The light cup 5 has an internal light channel 5a, which is the path for light to travel from the first light-emitting element 21 to the outside of the luminaire. The first light-emitting element 21 is positioned near the end of the light channel 5a close to the first circuit board 2, ensuring that light can be effectively transmitted from the light source to the light cup 5 and finally emitted through the opening of the light cup 5. By placing the first light-emitting element 21 near the end of the light cup 5 and forming the light channel 5a inside the light cup 5, light can be effectively transmitted from the light source to the outside of the luminaire, reducing light loss during propagation. The two ends of the light cup 5 are connected to the second circuit board 3 and the housing 1 respectively, providing a stable structure that helps protect the internal light-emitting elements and ensures the overall stability of the luminaire. The design of the light cup 5 optimizes the heat dissipation path, helping to conduct the heat generated by the first light-emitting element 21 to the housing 1 through the light cup 5, thereby improving the heat dissipation efficiency of the luminaire and extending the lifespan of the LED. The internal light channel 5a of the light reflector 5 can focus and distribute light rationally, resulting in more concentrated light output and improved lighting effect. The tilt angle of the light reflector 5 can also be specifically designed according to LED lights to better optimize light output and adapt to different lighting needs and aesthetic requirements.

[0035] In one embodiment of this utility model, please refer to Figure 1 The cross-sectional area of ​​the light channel 5a gradually increases along the direction from the first circuit board 2 to the second circuit board 3.

[0036] In this embodiment, the cross-sectional area of ​​the light channel 5a inside the light cup 5 gradually increases along the direction from the first circuit board 2 to the second circuit board 3. This open design utilizes the gradually widening structure of the light cup 5 to optimize the propagation and distribution of light, achieving uniform light distribution and enhanced luminous efficiency. It effectively reduces light loss during propagation and ensures that the light is more evenly distributed after reflection inside the light cup 5. This design not only improves the lighting efficiency of the luminaire but also helps reduce light spots and shadows, resulting in a softer and more uniform lighting effect. Furthermore, this structure also contributes to improving the aesthetics of the luminaire, as the uniform light distribution reduces glare and provides a more comfortable visual experience.

[0037] In one embodiment of this utility model, please refer to Figure 1 and Figure 4 The LED lamp 100 also includes a lampshade 6, a connecting groove 1b is provided in the mounting groove 1a, one end of the lampshade 6 is connected to the connecting groove 1b, and the other end of the lampshade 6 abuts against the groove opening of the mounting groove 1a. The lampshade 6 is provided with a receiving cavity 6a, and the first circuit board 2, the second circuit board 3 and the light cup 5 are all located in the receiving cavity 6a.

[0038] In one embodiment, the LED lamp 100 further includes a lampshade 6. One end of the lampshade 6 is designed with a structure that matches the connecting groove 1b in the mounting groove 1a, allowing it to be connected to the connecting groove 1b using adhesive or other materials. The other end of the lampshade 6 is tightly abutted against the opening of the mounting groove 1a, forming a closed structure. Inside the lampshade 6, a receiving cavity 6a is designed. This receiving cavity 6a is large enough to simultaneously accommodate the first circuit board 2, the second circuit board 3, and the light reflector 5, ensuring that these components are stably fixed inside the lampshade 6. The lampshade 6 provides additional physical protection for the internal components of the first circuit board 2, the second circuit board 3, and the light reflector 5, preventing dust, moisture, and other external factors from damaging the internal components of the lamp, thereby extending the lifespan of the lamp. The design of one end of the lampshade 6 connecting to the connecting groove 1b and the other end abutting against the opening of the mounting groove 1a enhances the structural stability of the entire lamp and reduces the risk of displacement or damage to internal components due to vibration or impact. The design of the housing cavity 6a of the lampshade 6 helps to better control the direction and intensity of light propagation, improve lighting efficiency, and at the same time reduce unnecessary light scattering and enhance the lighting effect.

[0039] In one embodiment of this utility model, please refer to Figure 2 The lampshade 6 is provided with a light guide 61 at one end near the cover 4. The light guide 61 is located around the light cup 5. The light guide 61 can refract the light from the second light-emitting element 31 to make the light more uniform.

[0040] In this embodiment, one end of the lampshade 6 is connected to the connecting groove 1b within the mounting groove 1a, while the other end is tightly abutted against the opening of the mounting groove 1a. A light guide 61 is specially designed at the end of the lampshade 6 near the cover 4. This light guide 61 is located around the periphery of the light cup 5, and its function is to refract the light emitted by the second light-emitting element 31 as it passes through, thereby making the light distribution more uniform. The main materials of the light guide include PMMA (polymethyl methacrylate), PC (polycarbonate), PS (polystyrene), or other new materials. The main advantage of this design is that it can achieve uniform light distribution and enhance luminous efficiency. By setting the light guide 61 inside the lampshade 6, the light from the second light-emitting element 31 can be refracted before being emitted, thereby reducing direct light exposure, reducing glare, and improving lighting comfort. At the same time, this design also helps to improve the overall aesthetics and design flexibility of the lamp, because the light guide 61 can be designed into different shapes and structures as needed to adapt to different lighting effects and design requirements. Furthermore, the design of the lampshade 6 provides additional protection for internal components, preventing dust and moisture intrusion and extending the lifespan of the lamp. The light guide 61 refracts light through its surface microstructure. When light enters the light guide 61 from a medium (such as air), it refracts at the interface due to the difference in refractive indices. The microstructures designed inside the light guide 61 cause multiple refractions of light as it passes through, thus dispersing the original light direction. Scattering principle: The light guide 61 contains scattering particles or has special uneven structures on its surface, which scatter light. When light enters these structures, it is reflected and refracted in different directions, causing the light originally concentrated at one point to disperse. Reflection principle: The surface or interior of the light guide 61 may also have reflective layers that can reflect light back to the source or propagate along a specific path, thus achieving uniform light distribution. Specifically, the light guide 61, through its special design, guides light to propagate in a predetermined direction, reducing direct light and increasing lateral and diffused light. By dispersing the intense light from LED point light sources, direct glare is reduced or eliminated, making lighting more comfortable. The illuminance of LED lamps is evenly distributed, avoiding areas of uneven brightness. Through scattering, the specific positions of LED beads are concealed, making the light source appear more continuous and natural. Different shapes and functions of light guides can be manufactured using various processing techniques, such as injection molding, extrusion, or coating.

[0041] In one embodiment of this utility model, please refer to Figure 1 and Figure 4 The bottom wall of the mounting groove 1a is provided with a vent hole 1c, which connects the receiving cavity 6a to the outside. The housing 1 includes a sealing element 11 that cooperates with the vent hole 1c.

[0042] In one embodiment, the bottom wall of the mounting groove 1a is specially designed with a vent 1c, which allows the receiving cavity 6a to communicate with the external environment. The presence of the vent 1c allows air circulation, which helps regulate the internal pressure and temperature of the lamp, while also preventing the accumulation of moisture and dust. The housing 1 includes a seal 11 that mates with the vent 1c. The seal 11 is designed to ensure the waterproof and dustproof performance of the lamp while maintaining the function of the vent 1c. The seal 11 can be a circular or square rubber material or silicone, which is installed around the vent 1c to ensure that the lamp's sealing performance is not affected while allowing air to pass through. The main advantage of this design is that it allows users to install the lampshade 6 more easily, preventing air pressure from making the installation of the lampshade 6 inconvenient. The vent 1c also helps to dissipate the heat generated when the LED lamp 100 is working, preventing the internal temperature of the lamp from becoming too high, thereby extending the lifespan of the LED. Meanwhile, the accompanying seal 11 ensures that the luminaire is breathable while preventing the intrusion of external moisture and dust, keeping the luminaire clean and dry, and improving its reliability and durability. Furthermore, this design simplifies maintenance and cleaning, as the vent 1c prevents dust accumulation, reducing the need for internal cleaning.

[0043] In one embodiment of this utility model, please refer to Figure 1 The second circuit board 3 is provided with a plurality of second light-emitting elements 31, and each second light-emitting element 31 is spaced apart on the second circuit board 3.

[0044] In this embodiment, the second circuit board 3 is designed to carry multiple second light-emitting elements 31, i.e., LED beads. These second light-emitting elements 31 are evenly distributed on the second circuit board 3, with a certain interval between each second light-emitting element 31. This layout allows light to be emitted from multiple point sources, and through the cooperation of the light cup 5 and the light guide 61, uniform light distribution and optimized lighting effect are achieved. The main advantage of this design is that it can provide a more uniform lighting effect. By arranging multiple light-emitting elements at intervals on the second circuit board 3, the shadows and light spots that may be produced by a single light source can be reduced, making the light softer and more evenly distributed. In addition, this design also helps to improve the luminous efficacy and energy efficiency of the lamp, because multiple light-emitting elements can work together to provide the required brightness while reducing energy consumption. The interval arrangement of the light-emitting elements also helps with heat dissipation, because there is enough space between each LED for heat dissipation, thereby reducing the risk of overheating and extending the life of the LED.

[0045] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 The housing 1 has a positioning hole 1d, and the end of the optical cup 5 near the bottom wall of the mounting groove 1a is provided with a positioning element 51 that cooperates with the positioning hole 1d.

[0046] In one embodiment, a positioning hole 1d is provided on the housing 1 for precise engagement between the housing 1 and the positioning element 51 of the light cup 5. The end of the light cup 5 near the bottom wall of the mounting groove 1a has a positioning element 51 that matches the positioning hole 1d on the housing 1. This design allows the light cup 5 to be accurately fixed in a predetermined position on the housing 1, ensuring the alignment accuracy of the light cup 5 with the second circuit board 3 and other components, thereby guaranteeing the assembly accuracy and lighting effect of the lamp. The main advantage of this design is improved assembly accuracy and reliability of the lamp components. The engagement of the positioning hole 1d on the housing 1 with the positioning element 51 of the light cup 5 ensures that the light cup 5 will not shift during installation, thus guaranteeing the optical performance and structural stability of the LED lamp 100. Furthermore, this precise positioning design helps simplify the assembly process, reduce assembly errors, and improve production efficiency. Simultaneously, the use of the positioning element 51 also helps improve the durability and lifespan of the lamp, as it reduces the risk of component damage due to improper installation.

[0047] In one embodiment of this utility model, please refer to Figure 1 and Figure 4 The housing 1 has a heat dissipation groove 1e, which is located at the end of the housing 1 away from the cover 4.

[0048] In this embodiment, heat dissipation grooves 1e are specifically provided in the housing 1, and these grooves 1e are located at the end of the housing 1 away from the cover 4. This design allows the heat dissipation grooves 1e to directly contact the external environment, facilitating heat dissipation. For example, a series of longitudinal or transverse grooves can be designed on the bottom or side of the housing 1. These grooves can increase the contact area between the housing 1 and the air, thereby improving heat dissipation efficiency. The main advantage of providing heat dissipation grooves 1e is that it can effectively enhance the heat dissipation performance of the LED lamp 100. By designing heat dissipation grooves 1e on the housing 1, the surface area of ​​the housing 1 can be increased, thereby improving the heat exchange efficiency with the surrounding air, accelerating heat dissipation, and reducing the operating temperature of the LED chip. This not only helps to extend the lifespan of the LED, but also maintains the luminous efficacy and performance stability of the lamp. In addition, a good heat dissipation design can reduce the risk of lamp damage due to overheating and improve the reliability and safety of the entire lamp system.

[0049] This utility model also proposes a means of transportation, which includes an LED lamp 100. The specific structure of the LED lamp 100 is as described in the above embodiments. Since this means of transportation adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0050] In this embodiment, the vehicle is typically a car or ship. Since cars have limited space, smaller lights offer more installation options. They can be installed in front, behind, above, below, or on the sides of an off-road vehicle; or on a ship, around the hull. Because of their small size, the lights won't damage the hull. They can serve as both main lights for illumination and background lighting for aesthetic purposes. Furthermore, each LED light fixture 100 can be arrayed in parallel or series to create ambiance. After arraying and connecting the LED lights 100, controlling simultaneous lighting, switching on / off, and dimming allows for the creation of personalized lighting environments and atmospheres.
