[0003] According to announcement number CN209418074U, a side-emitting LED digital tube is used as a display window when in operation, with the upper surface of the vertical part of the L-shaped byte filler serving as the display window. The L-shaped byte filler design is beneficial for the good fixation of the byte filler between the housing and the PCB board, because the horizontal part is located between the housing and the PCB board and plays a role in limiting the specific vertical position of the byte filler inside the housing, making the whole structure more stable.

[0004] The aforementioned byte filler can achieve lateral light emission and make the entire structure more stable. However, during the operation of the LED light source, heat is generated and stored inside the housing, causing the overall internal temperature of the LED digital tube to rise and not easily dissipate, thus affecting the normal use of the LED light source and reducing its lifespan.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, a side-emitting LED digital tube includes a PCB board 1. A mounting bracket 2 is fixedly connected to one side of the top of the PCB board 1. The mounting bracket 2 is L-shaped. Multiple heat dissipation grooves 3 are opened on the top of the mounting bracket 2. Support blocks 4 are correspondingly arranged at the bottom of the heat dissipation grooves 3. An LED digital tube 5 is arranged on the top of the PCB board 1. Multiple mounting ports 6 are opened on one side of the LED digital tube 5. The number of mounting ports 6 corresponds to the number of support blocks 4. Heat dissipation fins 7 are slidably connected inside the mounting ports 6 and the support blocks 4. A sealing gasket 8 is arranged between the heat dissipation fins 7 and the LED digital tube 5.

[0024] The sealing gasket 8 is placed on the surface of the heat dissipation fin 7, and the heat dissipation fin 7 is inserted into the LED digital tube 5 through the mounting port 6. After moving to a certain depth, the heat dissipation fin 7 is moved between the support block 4 and the mounting bracket 2, and corresponds to the position of the heat dissipation groove 3. The heat dissipation fin 7 is fixed in the mounting port 6 with glue, and the sealing gasket 8 is used to ensure the sealing of the connection to prevent foreign objects from entering. When the LED light source 18 is working, the heat dissipation fin 7 can conduct the internal heat to the outside. The heat dissipation fin 7 adopts a T-shaped structure, so that the heat is conducted through the horizontal plate and then dissipated into the air through the vertical plate. The vertical plate is made of thin copper sheet material, and the contact area with the air is increased, thereby improving the heat dissipation effect of the LED digital tube 5.

[0025] A protrusion 9 is fixedly connected to the top of the PCB board 1. A sealing gasket 2 10 is fixedly fitted onto the surface of the protrusion 9. The sealing gasket 2 10 is located between the LED digital tube 5 and the PCB board 1. Multiple soldering points 11 are provided on one side of the top of the PCB board 1.

[0026] The bottom of the LED digital tube 5 has a groove 12, which is matched with the protrusion 9.

[0027] Place the sealing gasket 2 10 on the surface of the protrusion 9, and align the groove 12 at the bottom of the LED digital tube 5 with the protrusion 9 at the top of the PCB board 1. Apply adhesive to the inside of the groove 12, press down on the LED digital tube 5, and make the protrusion 9 engage inside the groove 12. Fix the position of the two with adhesive. At the same time, the LED digital tube 5 and the PCB board 1 squeeze the sealing gasket 2 10 to make the connection sealed, thereby improving the overall sealing effect.

[0028] An installation groove 13 is provided on one side of the bottom of the LED digital tube 5, and a light shield 14 is provided inside the installation groove 13.

[0029] The top of the mounting bracket 2 has multiple insertion holes 15, and the bottom of the insertion holes 15 is welded with guide sleeves 16. The guide sleeves 16 and the welding points 11 are located on the same axis.

[0030] The guide sleeve 16 and the socket 15 are internally slidably connected with pins 17. The bottom of pins 17 is located inside the solder joint 11. The top of pins 17 is fixedly connected with an LED light source 18. The LED light source 18 is in contact with the inner wall of the light shield 14.

[0031] The pin 17 at the bottom of the LED light source 18 is passed through the socket 15 and the guide sleeve 16 and corresponds to the solder point 11. The pin 17 is fixed on the PCB board 1 using a soldering tool, thereby completing the connection between the LED light source 18 and the PCB board 1. The guide sleeve 16 can protect the pin 17.

[0032] The bottom of the mounting bracket 2 is symmetrically provided with connecting blocks 19 on both sides. A semi-circular protrusion is fixedly connected to the bottom of the connecting block 19. The semi-circular protrusion is made of silicone. A support base 20 is provided at the bottom of the connecting plate. A V-shaped groove 21 is opened at the top of the support base 20. The V-shaped groove 21 is in contact with the semi-circular protrusion.

[0033] By setting connecting blocks 19 on both sides of the mounting bracket 2 and contacting the support base 20, the mounting bracket 2 is supported. When the LED digital tube 5 is squeezed, the semi-circular convex strip at the bottom of the connecting plate slides inside the V-groove 21. The semi-circular convex strip is squeezed and deformed, thereby absorbing external force and improving the protection of the LED digital tube 5.

[0034] This utility model provides a side-emitting LED digital tube, the specific working principle of which is as follows:

[0035] In use, the pin 17 at the bottom of the LED light source 18 is passed through the socket 15 and guide sleeve 16 and aligned with the solder point 11. The pin 17 is fixed to the PCB board 1 using a soldering tool. The sealing gasket 2 10 is placed on the surface of the bump 9, and the groove 12 at the bottom of the LED digital tube 5 is aligned with the bump 9 at the top of the PCB board 1. Glue is applied inside the groove 12. The LED digital tube 5 is pressed down to make the bump 9 engage inside the groove 12, and the positions of the two are fixed by the glue. At this time, the light shield 14 is in contact with the LED light source 18. The sealing gasket 1 8 is then placed on the surface of the heat sink fin 7. The heat sink 7 is inserted into the LED digital tube 5 through the mounting port 6. After moving to a certain depth, the heat sink 7 is moved between the support block 4 and the mounting bracket 2, and corresponds to the position of the heat sink 3. The heat sink 7 is fixed in the mounting port 6 with glue. When the LED digital tube 5 is working, the light shield 14 blocks the light from the LED light source 18 on three sides, so that the light can only be emitted from the side of the LED digital tube 5, thereby realizing side light emission. At the same time, the heat generated by the LED light source 18 is conducted to the outside through the heat sink 7, so that the internal temperature of the LED digital tube 5 is at a normal level.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
