It also has the advantages of efficient heat dissipation, thereby solving the related defects of traditional tubes.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] This utility model provides an LED waterproof glass tube, including a tube body and a pair of end cap assemblies. The tube body is composed of a glass tube and a PC tube sleeved inside it.

[0013] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Figure 3 This is a schematic diagram of the exploded structure of the lamp tube. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 and Figure 3 As shown, in this embodiment, the present invention includes a lamp tube body 1 and a pair of plug assemblies 2. The lamp tube body 1 is composed of a glass tube 10 and a PC tube 11 sleeved therein. The pair of plug assemblies 2 are fitted to the two ends of the lamp tube body 1. An aluminum substrate 12 and a light source component 13 are provided inside the PC tube 11. The light source component 13 is mounted on the aluminum substrate 12 and has an input line. The input line is led out through the wire hole of the plug assembly 2 and electrically connected to an external device. Therefore, the glass tube 10, as the outermost protective structure, provides basic support and physical protection for the PC tube 11, preventing internal components from being directly exposed to the external environment. The PC tube 11 has high transparency, impact resistance, and high temperature resistance, and can also protect internal electrical components while also transmitting light. The plug assembly 2 fixes the position of the lamp body and internal components, preventing loosening or sliding. It also prevents dust and moisture from entering the interior, ensuring electrical safety. The aluminum substrate 12 supports the light source component 13, utilizing the high thermal conductivity of aluminum to quickly dissipate the heat generated by the LED lamp during operation, preventing light decay or damage caused by overheating. The light source component 13 is the light-emitting unit of the lamp tube, converting electrical energy into visible light. The input line transmits electrical energy from the external power source to the aluminum substrate circuit through the plug wire hole, and also transmits control signals such as dimming and color temperature adjustment. This design not only balances strength and light transmittance, improving durability, but also has a heat dissipation design to extend the life of the light source.

[0020] Furthermore, in this embodiment, the plug assembly 2 includes a plug retaining ring 20, a waterproof component 21, and a plug element 22. The plug retaining ring 20 is positioned at one end of the lamp tube body 1, and the plug retaining ring 20 is threadedly engaged with the plug element 22. The waterproof component 21 is positioned within the plug element 22. Thus, the plug retaining ring 20, through its threaded connection with the plug element 22, provides a stable and fixed position for the entire plug assembly 2 at both ends of the lamp tube body 1, preventing internal components from shifting due to vibration or external force. The waterproof component 21, through elastic deformation, fills the gap between the plug element 22 and the lamp tube body 1, effectively preventing the intrusion of moisture, humidity, and dust. The plug element 22 is the supporting component of the plug assembly 2, providing support for the waterproof component 21 and the plug retaining ring 20, forming a complete sealed cavity to protect the internal light source and circuitry.

[0021] Furthermore, in this embodiment, the light source on the light source component 13 is an LED light source. Therefore, the light source component is a full-spectrum LED light source, which has lower energy consumption and a longer lifespan, far exceeding that of fluorescent lamps and incandescent lamps.

[0022] Furthermore, in this embodiment, the PC tube 11 is provided with a limiting part that cooperates with the aluminum substrate 12. Thus, the PC tube 11 provides support and fixation for the limiting part. The slots in the internal structure of the PC tube 11 cooperate with the notches on the edge of the aluminum substrate 12, firmly limiting the aluminum substrate 12 within the PC tube 11 and preventing displacement due to vibration, impact, or thermal expansion and contraction.

[0023] Furthermore, in this embodiment, the waterproof component 21 includes a waterproof rubber ring 210 and a waterproof rubber plug 211. The waterproof rubber ring 210 is confined within the plug fixing ring 20, and the waterproof rubber plug 211 is confined within the plug element 22. Thus, the waterproof rubber ring 210, nested within the plug fixing ring 20, fills the gap between the plug fixing ring 20 and the end face of the lamp tube body 1 through elastic deformation, forming the first waterproof barrier. The waterproof rubber plug 211 is nested within the inner wall of the plug element 22, and simultaneously wraps the input wire through the central through-hole, using elastic deformation to seal the cable against the hole wall, further enhancing waterproofing and ensuring long-term stable operation of the LED lamp in humid environments such as outdoors and bathrooms.

[0024] Optionally, in this embodiment, both the plug retaining ring 20 and the plug element 22 are provided with a plurality of anti-slip protrusions on their exteriors. The anti-slip protrusions are striped or granular protrusions. Thus, the plug retaining ring 20 and the plug element 22 provide support and fixation for the anti-slip protrusions, which increase the friction between the hand and the plug surface.

[0025] The working principle of this utility model is as follows:

[0026] The PC tube 11 is inserted into the glass tube 10, and then the edge of the aluminum substrate 12 is snapped into the limiting part of the PC tube 11. The light source component 13 is used to mount the LED chip onto the aluminum substrate 12 through SMT process and solder the input line. The plug fixing ring 20 and the plug element 22 are connected by threads and assembled at both ends of the lamp tube body 1. Then, the power supply is connected through the input line, and the LED is tested to see if it is emitting light normally. The IP67 waterproof performance is verified using an airtightness tester. This process is repeated.

[0027] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
