Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a plastic plug-in tube lamp. Background Technology

[0002] Plastic pluggable LED lights generally have poorer heat dissipation performance than metal ones, which can lead to overheating issues during prolonged operation. While LEDs, as solid-state lighting fixtures, offer advantages such as high efficiency and long lifespan, their performance and lifespan are significantly affected by operating temperature. When the temperature of an LED light exceeds its designed maximum operating temperature, the following problems may occur:

[0003] 1. As the temperature rises, the internal quantum efficiency of LED chips decreases, leading to reduced light output. In addition, high temperatures can cause thermal expansion of LED chips and packaging materials, resulting in internal stress and further affecting luminous efficiency.

[0004] 2. The lifespan of LEDs is closely related to temperature. High temperatures accelerate their aging process, causing the internal semiconductor materials to degrade, thereby reducing their lifespan.

[0005] 3. Increased temperature not only affects the brightness of light, but also its color, reducing color stability. Specifically, LEDs may experience color shift at high temperatures, meaning the color of the light deviates from its initial design value, affecting lighting quality.

[0006] 4. Plastic materials have poor thermal conductivity, which is not conducive to the rapid conduction and dissipation of heat. This can easily lead to heat accumulation inside the LED light, forming a heat island effect and further exacerbating the above problems.

[0007] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0029] Please see Figures 1 to 4 This utility model provides a plastic pluggable tube lamp, including a lampshade 1, a lamp holder 2, an end cap 3, a lamp plate 4, a driver plate 5, and a heat sink 6; the lamp holder 2 and the end cap 3 are respectively disposed at both ends of the lampshade 1; the heat sink 6 is disposed inside the lampshade 1, and both ends of the heat sink 6 are fixedly connected to the lamp holder 2 and the end cap respectively; a first limiting block 62 is respectively disposed on both sides of the heat sink 6, and a limiting groove is formed between the lower surface of the first limiting block 62 and the upper surface of the heat sink 6, and the lamp plate 4 is located in the limiting groove; the driver plate 5 is disposed inside the lamp holder 2, and the driver plate 5 is electrically connected to the lamp plate 4.

[0030] This application discloses a plastic pluggable tube lamp. By setting a heat sink 6, the heat generated by the lamp plate 4 can be quickly conducted to the lamp head 2 and the external mounting position of the end cover 3, effectively breaking the heat island effect of the plastic material. While maintaining the advantage of lightweight material, it greatly improves the heat dissipation efficiency of the plastic pluggable tube lamp and effectively extends the service life of the plastic pluggable tube lamp. Furthermore, the limiting groove structure makes the lamp plate 4 and the heat sink 6 fit tightly, greatly increasing the contact area and contact stability between the lamp plate 4 and the heat sink 6, ensuring that the working temperature of the lamp plate 4 can be effectively reduced, fundamentally suppressing light decay and color shift phenomena.

[0031] In this embodiment, the heat sink 6 is made of aluminum alloy.

[0032] Further, please refer to Figures 1 to 4 The heat sink 6 is provided with connecting posts 61 on both sides, and the two ends of the connecting posts 61 are fixedly connected to the lamp head 2 and the end cover respectively; two first limiting blocks 62 are respectively provided on the inner side of the two connecting posts 61, and the two first limiting blocks 62 are arranged opposite to each other.

[0033] In this embodiment, the connecting post 61 is integrally formed with the heat sink 6, and the first limiting block 62 is integrally formed with the connecting post 61. By setting the connecting post 61 on both sides of the heat sink 6 and fixing the two ends of the connecting post 61 to the lamp holder 2 and the end cover respectively, the connection stability between the heat sink 6 and the lamp holder 2 and the end cover is enhanced, preventing the lamp components from loosening or being damaged due to external forces during use, thereby extending the service life of the lamp. In addition, the two connecting posts 61 can form a dual-channel heat conduction structure, which helps to improve the heat dissipation efficiency of the heat sink 6 and ensure that the lamp can work stably and efficiently.

[0034] Further, please refer to Figure 4 The inner walls on both sides of the lampshade 1 are respectively provided with second limiting blocks 11, which are used to limit the movement position of the heat sink 6.

[0035] In this embodiment, the second limiting block 11 is integrally formed with the lampshade 1; by setting the second limiting block 11 on the inner walls of both sides of the lampshade 1, the movement range of the heat sink 6 can be effectively limited, preventing unnecessary displacement during operation, thereby ensuring the stability and reliability of the heat sink 6, and confirming the contact stability between the heat sink 6 and the lamp plate 4.

[0036] Further, please refer to Figure 4 The end cap 3 includes a base 31 and a cover plate 32. The base 31 has two first connecting holes 311. One end of each of the two connecting posts 61 is bolted to the two first connecting holes 311. The end cap 3 is located on the outside of the base 31 and is snapped into the base 31.

[0037] In this embodiment, the first connecting holes 311 are located on both sides of the bottom of the base 31. The two first connecting holes 311 on the base 31 are bolted to the connecting post 61, achieving a stable connection between the end cover 3 and the radiator 6, thus improving the stability and reliability of the entire structure. The bolt connection method is not only simple and convenient but also capable of withstanding significant force and torque, ensuring that the radiator 6 will not loosen or fall off during operation. Furthermore, the cover plate 32 is located on the outside of the base 31 and is connected to the base 31 via a snap-fit ​​method. This simplifies the installation and disassembly process and improves the sealing performance of the end cover 3. The snap-fit ​​method ensures a tight fit between the cover plate 32 and the base 31, preventing dust, moisture, and other impurities from entering the pluggable tube lamp, thereby extending the service life of the driver board 5 and the lamp board 4. In addition, the cover plate 32 can also be used to cover the bolt connection points of the base 31, improving the overall aesthetics of the pluggable tube lamp.

[0038] Further, please refer to Figure 3 and Figure 4The cover plate 32 has two first locking blocks 321 on each side and a positioning post 322 on the top. The base 31 has two first locking slots 312 on each side and a positioning groove 313 on the top. The two first locking blocks 321 are respectively connected to the two first locking slots 312, and the positioning post 322 is connected to the positioning groove 313.

[0039] In this embodiment, the first locking block 321 is integrally formed with the cover plate 32, and the positioning post 322 is integrally formed with the cover plate 32. By setting two first locking blocks 321 on both sides of the cover plate 32 and two first locking slots 312 on both sides of the base 31, a quick and stable locking connection between the cover plate 32 and the base 31 is achieved, which can greatly improve the assembly efficiency. The positioning post 322 on the top of the cover plate 32 and the positioning slot 313 on the top of the base 31 cooperate to connect, further enhancing the connection stability between the cover plate 32 and the base 31, ensuring the accurate positioning of the cover plate 32 on the base 31, avoiding assembly problems caused by positional offset, thereby improving the reliability and durability of the entire end cover 3.

The drive plate 5 is disposed inside the power supply compartment 22, and a connecting plate 221 is provided at the end of the power supply compartment 22. The connecting plate 221 has two second connecting holes 222, and the other ends of the two connecting posts 61 are respectively bolted to the two second connecting holes 222.

[0041] In this embodiment, the connecting plate 221 is integrally formed with the power compartment 22. The connecting plate 221 is bolted to the connecting column 61 through two second connecting holes 222 on the connecting plate 221, which realizes a stable connection between the lamp head 2 and the heat sink 6, improves the stability and reliability of the entire structure, and further ensures that the heat sink 6 will not loosen or fall off during operation.

[0042] Further, please refer to Figure 2 and Figure 4 The power supply compartment 22 has guide blocks 223 on both sides, and guide grooves are provided in the middle of the guide blocks 223. The two sides of the drive plate 5 are slidably engaged with the two guide grooves respectively.

[0043] In this embodiment, the guide block 223 is integrally formed with the power supply compartment 22, and the drive plate 5 is slidably inserted and removed through the guide groove, which can improve the installation and positioning accuracy of the drive plate 5, reduce installation errors caused by manual operation, and ensure reliable and stable electrical connection between the drive plate 5 and the lamp board 4. When maintenance of the drive plate 5 is required, the guide groove can shorten the disassembly and assembly time, which not only improves maintenance efficiency but also reduces downtime for inserting and removing lamps. In addition, after assembly, the guide groove can limit the movement position of the drive plate 5, preventing displacement caused by vibration, impact or other external forces, which helps to maintain good electrical contact between the drive plate 5 and the lamp board 4, while avoiding mechanical stress or damage that may be caused by positional deviation, thus reducing the failure rate.

[0044] Further, please refer to Figure 2 and Figure 4 The drive board 5 has a first connecting pin 51 and a second connecting pin 52 at both ends, the lamp board 4 has an electrical connector 41 at the other end, and the lamp head 2 has a copper pin 23. The first connecting pin 51 is electrically connected to the electrical connector 41, and the second connecting pin 52 is electrically connected to the copper pin 23. The copper pin 23 is used to connect to an external power supply device.

[0045] In this embodiment, the first connecting pin 51 and the second connecting pin 52 are made of copper, and the external power supply device can be an electrical socket at the installation position. The separate plug-in structure of the connecting pin, the electrical connector 41, and the copper pin 23 ensures that the second connecting pin 52 can make close contact with the electrical connector 41 during the plugging process, thereby ensuring the transmission of current without attenuation. It is suitable for occasions with frequent plugging and unplugging, such as the replacement or maintenance of tube lights. It can reduce power loss and heat effects caused by poor contact and extend the service life of tube lights. Furthermore, with the separate plug-in structure, the drive board 5 can be quickly installed or removed through simple plugging and unplugging actions, which greatly shortens the replacement time and improves maintenance efficiency.

[0046] Furthermore, the inner walls on both sides of the lamp holder 21 are respectively provided with second slots, and the inner walls on both sides of the power compartment 22 are respectively provided with second blocks, which are connected to the second slots.

[0047] In this embodiment, the second locking block is integrally formed with the power compartment 22. By setting two second locking blocks on both sides of the power compartment 22 and two second locking slots on both sides of the lamp holder 21, a fast and stable locking connection between the lamp holder 21 and the power compartment 22 is achieved, which can greatly improve the assembly efficiency.

[0048] Further, please refer to Figures 1 to 3The lamp head 2 is provided with a third locking block 24 on each side, and the third locking block 24 is used to fix the plastic plug-in tube lamp to the mounting position.

[0049] In this embodiment, the third locking block 24 is integrally formed with the lamp head 2. By setting the third locking block 24 on both sides of the lamp head 2, a quick and stable fixed connection between the plastic plug-in tube lamp and the mounting position is achieved. This not only simplifies the installation process and reduces the installation difficulty, but also improves the installation efficiency, making the deployment and maintenance of plug-in tube lamps more convenient.
