[0021] Figure 3 This is the second structural schematic diagram of a welcome lamp with a heat dissipation structure of the utility model. DETAILED DESCRIPTION

[0022] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 3 A welcome lamp with a heat dissipation structure shown in the figure comprises an outer shell 1, a heat dissipation shell 2 located on the back of the outer shell 1 and connected to the outer shell 1, the outer shell 1 is provided with a mounting cavity on one side close to the heat dissipation shell 2, the heat dissipation shell 2 is provided with a heat dissipation component 3 for absorbing heat on one side close to the mounting cavity, a heat dissipation channel 4 is provided in the space enclosed by the inner cavity of the heat dissipation shell 2 and the mounting cavity, and a heat dissipation port 5 is provided on the side of the heat dissipation channel 4 facing away from the outer shell 1, so that the heat on the heat dissipation component 3 is discharged to the outside through the heat dissipation port 5;

[0024] The utility model is provided with a heat dissipation channel in the space enclosed by the inner cavity of the heat dissipation shell and the installation cavity, the heat dissipation shell is provided with a heat dissipation component, the LED lamp in the device is connected to the heat dissipation component, the heat generated by the LED lamp during normal operation is diffused to the heat dissipation component behind it, the heat dissipation component is made of metal material, the metal material has good thermal conductivity and can transfer part of the heat to the outside, the heat dissipation port is provided on the side of the heat dissipation channel facing away from the outer shell, so that the remaining heat can be discharged to the outside through the heat dissipation port, and the setting of the heat dissipation port is conducive to air circulation, which effectively solves the problem that the internal temperature of the existing welcome lamp continues to rise when it is used for a long time or in a high temperature environment, and the device adopts a closed structure, thereby restricting air circulation, resulting in poor heat dissipation effect inside the device, affecting the performance and service life of the device.

[0025] like Figures 1 to 3 The heat dissipation assembly 3 shown includes a plurality of first metal heat dissipation blocks 31 located near the heat dissipation port 5 and arranged at intervals, and a first heat dissipation channel 311 facing the heat dissipation port 5 is provided between each adjacent first metal heat dissipation block 31;

[0026] Furthermore, the first metal heat dissipation block 31 has good thermal conductivity and can quickly absorb and conduct the heat generated by the welcome lamp.

[0027] Furthermore, the spacing of the first metal heat dissipation blocks 31 is beneficial to increasing the heat dissipation area, accelerating the heat dissipation speed, and allowing the heat to be conducted and dissipated to the external environment more quickly, which is beneficial to improving the heat dissipation efficiency, avoiding damage to the internal components of the device due to high temperature, and effectively improving the overall performance and stability of the device.

[0028] Furthermore, a first heat dissipation channel 311 facing the heat dissipation port 5 is provided between each adjacent first metal heat dissipation block 31, so that air can form convection between the heat dissipation port 5 and the first heat dissipation channel 311, further enhancing the heat dissipation effect. By utilizing the effect of convection, it helps to quickly discharge the heat inside the device to the external environment.

[0029] Specifically, each first metal heat dissipation block 31 is in the shape of an elongated strip and is evenly spaced, so that the structure of the heat dissipation assembly 3 is more compact, occupies less space, and is conducive to improving the practicability of the device.

[0030] like Figures 1 to 3 The heat dissipation assembly 3 shown also includes an auxiliary heat dissipation seat 32 located on one side of the first metal heat dissipation block 31, and the auxiliary heat dissipation seat 32 and the inner wall of the outer shell 1 are enclosed to form an auxiliary heat dissipation channel, and the auxiliary heat dissipation channel is provided with an auxiliary heat dissipation port 30 for discharging the heat on the auxiliary heat dissipation seat 32 to the outside on the side facing the outside;

[0031] Furthermore, by providing the auxiliary heat sink 32 and enclosing the inner wall of the outer shell 1 to form an auxiliary heat dissipation channel, the heat dissipation area is significantly increased, which helps to more quickly absorb and disperse the heat from the inside of the device.

[0032] Furthermore, the combination of the auxiliary heat dissipation channel and the auxiliary heat dissipation port 30 provides another heat dissipation path, and heat can be directly discharged from the auxiliary heat dissipation seat 32 to the external environment through the auxiliary heat dissipation channel, reducing heat accumulation on the heat dissipation component 3, thereby improving the overall heat dissipation efficiency.

[0033] Furthermore, through the combined effect of the heat dissipation channel 4 and the auxiliary heat dissipation channel, a more uniform heat dissipation effect can be achieved, which helps to prevent local overheating and is beneficial to improving the service life and performance stability of the device.

[0034] Specifically, the heat dissipation port 5 and the heat dissipation channel 4 are located in the middle of the device, which can more effectively absorb and conduct the core heat source from the inside of the device, ensuring that the heat can quickly diffuse outward from the central area, while the auxiliary heat dissipation channel and the auxiliary heat dissipation port 30 are located on one side, which can cooperate with the heat dissipation channel 4 to dissipate heat, further dissipate heat to a wider area, and improve the overall heat dissipation efficiency.

[0035] like Figures 1 to 3 The auxiliary heat sink 32 shown includes a plurality of heat dissipation grooves 321 arranged at intervals;

[0036] Furthermore, the setting of the heat dissipation grooves 321 can effectively increase the surface area of ​​the heat dissipation area, improve heat transfer and heat dissipation efficiency, and each heat dissipation groove 321 can increase the surface area for heat dissipation, thereby accelerating the heat dissipation speed and ensuring that the heat dissipation effect of the auxiliary heat dissipation seat 32 is more effective.

[0037] Furthermore, the heat dissipation groove 321 can greatly reduce the thermal resistance between the surface of the auxiliary heat sink 32 and the air, which is beneficial to improving the heat transfer efficiency, so that heat can be transferred from the surface of the auxiliary heat sink 32 to the air more quickly, accelerating the dissipation of heat, ensuring that the internal temperature of the device remains within a normal range, and effectively extending the service life of the device.

[0038] Furthermore, by setting the heat dissipation grooves 321 at intervals, the heat can be more evenly distributed on the surface of the auxiliary heat dissipation seat 32, thereby improving the heat dissipation balance. Each heat dissipation groove 321 can evenly absorb and release heat, avoiding the generation of local high temperature areas, and ensuring a more stable heat dissipation effect.

[0039] like Figures 1 to 3 An optical projector 6 located on the mounting cavity and a decoder board assembly 7 connected to the optical projector 6 are provided between the outer shell 1 and the heat dissipation shell 2. A signal transmission assembly 8 for transmitting electrical signals and data to the optical projector 6 and the decoder board assembly 7 is provided on a side of the optical projector 6 away from the auxiliary heat dissipation seat 32;

[0040] Furthermore, the signal transmission component 8 is located on a side away from the auxiliary heat sink 32, which is beneficial to avoid direct heat exchange between the signal transmission component 8 and the auxiliary heat sink 32, thereby effectively protecting the signal transmission component 8 and extending the service life of the device.

[0041] Furthermore, the optical projector 6, the heat dissipation channel 4 and the heat dissipation port 5 are located in the same straight line, so that heat can be directly generated from the optical projector 6, quickly conducted to the heat dissipation port 5 through the heat dissipation channel 4, and then directly discharged into the environment. The setting of the same straight line is conducive to reducing the path and resistance of heat transfer, thereby improving the heat dissipation efficiency.

[0042] Furthermore, by rationally arranging the optical projector 6, the decoder board assembly 7 and the signal transmission assembly 8 on the installation cavity, the internal structure of the entire device is made more compact and orderly, thereby effectively improving the space utilization.

[0043] Specifically, the signal transmission component 8 transmits the signal to the optical projector 6 and the decoder board component 7. After receiving the signal, the optical projector 6 converts it into a visual image and projects it through the light. The decoder board component 7 is responsible for parsing the input signal and controlling the behavior of the light, such as color, brightness, etc., according to the preset logic.

[0044] like Figures 1 to 3 The signal transmission component 8 shown includes an adapter plate 81 connected to the optical projector 6 and the decoder board component 7 respectively, a straight pin 82 connected to the adapter plate 81 and arranged in the vertical direction, and a curved pin 83 connected to the adapter plate 81 and arranged in the horizontal direction;

[0045] Furthermore, arranging the straight pin header 82 and the curved pin header 83 in different directions can more effectively utilize space, avoid cross interference between components, and help make the overall structure more compact; secondly, the straight pin header 82 and the curved pin header 83 are respectively connected in the vertical and horizontal directions, which can increase the stability of the connection, reduce the looseness problem during plugging and unplugging, and improve the reliability of signal transmission.

[0046] Furthermore, since the adapter plate 81 and the straight pin headers 82 and the curved pin headers 83 are all modularly configured, when repair or replacement of components is required, the specified components can be individually removed and replaced without disassembling the entire system, which helps to improve the maintainability and maintenance efficiency of the system.

[0047] Optionally, the straight pin header 82 and the curved pin header 83 may be connected to the adapter board 81 by welding, plugging, or other connection methods.

[0048] like Figures 1 to 3 The heat dissipation housing 2 shown is provided with a connection groove 21 connected to the optical mechanical projector 6 and having a shape corresponding to the outer side wall of the optical mechanical projector 6 on one side thereof;

[0049] Furthermore, by providing a tight fit between the connecting groove 21 of corresponding shape and the outer wall of the optical mechanical projector 6, the stability of the optical mechanical projector 6 in the heat dissipation housing 2 can be ensured, which is beneficial to reducing the possibility of movement or position change of the optical mechanical projector 6 due to vibration or other external factors, thereby ensuring the stable operation of the system.

[0050] like Figures 1 to 3 The heat dissipation housing 2 shown is made of metal;

[0051] Furthermore, the metal material has good thermal conductivity, can quickly absorb and conduct the heat generated inside the device, and effectively improve the heat dissipation effect. The metal heat dissipation shell 2 can effectively dissipate heat from the inside of the device to the external environment, which helps to keep the operating temperature of the device within a safe range.

[0052] Furthermore, metal material has high strength and durability, and can provide stable external protection for the device. The heat dissipation housing 2 is made of metal material, which can effectively resist external impact or extrusion force, thereby protecting the internal components of the device from damage.

[0053] Furthermore, metal materials can effectively shield external electromagnetic interference, reduce the impact of external interference on the internal electronic components of the device, and help improve the stability and reliability of the device.

[0054] like Figures 1 to 3 A connecting component 9 is provided between the outer shell 1 and the heat dissipation shell 2, and the outer shell 1 is detachably connected to the heat dissipation shell 2 via the connecting component 9;

[0055] Furthermore, through the setting of the detachable connection, the assembly and disassembly between the outer shell 1 and the heat dissipation shell 2 become easier. When the device needs to be repaired or upgraded, the user can easily remove the connection between the outer shell 1 and the heat dissipation shell 2 to access the internal components of the device, and then reinstall it after completing the necessary repairs or upgrades, which helps to simplify the repair and upgrade process and effectively improve work efficiency.

[0056] Furthermore, over time, dust or other dirt may accumulate between the outer shell 1 and the heat dissipation shell 2, affecting the heat dissipation performance. The user can use the detachable connection setting to easily disassemble the outer shell 1 for cleaning, thereby maintaining the cleanliness and heat dissipation performance of the device.

[0057] Optionally, in some embodiments, the connection between the outer shell 1 and the heat dissipation shell 2 can be achieved by a snap connection, an elastic clamp connection, a buckle connection, a plug-in connection or the like.

[0058] like Figures 1 to 3 The connecting assembly 9 shown includes a first connecting hole 91 located on the outer shell 1, and a second connecting hole 92 located on the heat dissipation shell 2 and threadedly connected to the first connecting hole 91;

[0059] Furthermore, as a preferred embodiment of the present invention but not a limitation, the outer shell 1 and the heat dissipation shell 2 are connected by threads.

[0060] Furthermore, through the threaded connection, a very stable connection can be formed between the outer shell 1 and the heat dissipation shell 2. This connection method can resist vibration and impact, and effectively ensure that the device can operate stably in various environments.

[0061] Furthermore, the outer shell 1 and the heat dissipation shell 2 can be easily disassembled and installed through the threaded connection, and the user can conveniently perform maintenance, cleaning or replacement of components, which is conducive to improving the maintainability of the equipment.
