Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an LED lamp tube. Background Technology

[0002] Currently, most commercially available LED tubes use an aluminum substrate as the carrier for the LED light-emitting chip. The aluminum substrate has excellent thermal conductivity, effectively dissipating the heat generated during LED operation, thus improving the stability and lifespan of the lamp. However, this type of LED tube has the following drawbacks: because the aluminum substrate is opaque and is usually directly attached to one side of the inner wall of the tube, the area where the aluminum substrate is attached cannot transmit light, creating obvious dark areas. This not only affects the overall uniformity of light emission but also limits its lighting effect, especially in applications requiring omnidirectional illumination (such as ring lighting or uniform supplemental lighting).

[0003] Furthermore, the existing LED tube structure design allows the light source to emit light only to one side or in a specific direction, failing to achieve 360° omnidirectional illumination and reducing luminous efficiency. Additionally, the tight fit between the aluminum substrate and the tube wall can lead to heat accumulation; insufficient heat dissipation design can negatively impact the LED's lifespan. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an LED tube with a simple structure, no dark areas, and the ability to emit light from all angles.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An LED tube includes an externally transparent tube having a through cavity extending along the axial direction. An LED light-emitting component is disposed inside the externally transparent tube. The LED light-emitting component includes a chip carrier and an LED light-emitting chip disposed on the chip carrier. The chip carrier is made of a transparent material. The LED light-emitting component is suspended inside the externally transparent tube.

[0007] The two ends of the external light-transmitting tube are respectively detachably fixed with positioning end caps, and the two ends of the chip carrier are positioned and installed through the two positioning end caps.

[0008] The inner end face of the positioning end cap is provided with a positioning groove for the chip carrier end to be embedded and installed, and the two ends of the chip carrier are respectively tightly fitted and embedded in the corresponding positioning groove.

[0009] An inner light-transmitting tube is suspended inside the outer light-transmitting tube, and the LED light-emitting component is disposed inside the inner light-transmitting tube. The maximum outer diameter of the LED light-emitting component matches the inner diameter of the inner light-transmitting tube.

[0010] The two ends of the internal light-transmitting tube are positioned and installed by the two positioning end caps.

[0011] The inner end face of the positioning end cap is provided with a positioning cavity for inserting and installing the end of the inner light-transmitting tube, and the two ends of the inner light-transmitting tube are respectively embedded and installed in the corresponding positioning cavity.

[0012] The inner light-transmitting tube and the outer light-transmitting tube are coaxially arranged.

[0013] The external light-transmitting lamp tube is provided with lamp tube connectors at both ends.

[0014] The LED light-emitting component is centrally suspended inside the external light-transmitting tube.

[0015] The chip carrier is made of glass.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] (1) Eliminate dark areas and improve light emission uniformity: Use transparent materials (such as glass, transparent ceramics or polymer materials) to replace the traditional opaque aluminum substrate as the chip carrier, so that the light source area can also transmit light, completely solving the dark area problem caused by the aluminum substrate in the traditional structure, realizing uniform light emission throughout the tube, suitable for high-requirement scenarios such as ring lighting, and broadening the market applicability of LED tubes.

[0018] (2) Achieve 360° omnidirectional light emission: The LED light-emitting components are suspended inside the light-transmitting tube, avoiding the directional limitation of the light source installed on one side of the wall in the traditional structure. The light can diffuse to all sides through the transparent carrier. Combined with the diffusion effect of the external light-transmitting tube, it achieves an all-round light emission effect and significantly improves the light efficiency.

[0019] (3) Heat dissipation optimization: The suspended design of the LED light-emitting component avoids the tight fit with the inner wall of the lamp tube in the traditional structure, reducing local heat accumulation. At the same time, if a high thermal conductivity material (such as transparent ceramic) is selected for the transparent carrier, it can take into account both light transmission and heat dissipation, thus optimizing the LED operating temperature and extending its service life.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1: As shown in the figure, an LED tube includes an external light-transmitting tube 1 with a through cavity extending along the axial direction. An LED light-emitting component is disposed inside the external light-transmitting tube 1. The LED light-emitting component includes a chip carrier 2 and an LED light-emitting chip (not shown in the figure) disposed on the chip carrier 2. The chip carrier 2 is made of transparent material, and the LED light-emitting component is suspended inside the external light-transmitting tube 1.

[0026] In this specific embodiment, positioning end caps 3 are detachably fixed to the two ends of the external light-transmitting tube 1, and the two ends of the chip carrier 2 are positioned and installed through the two positioning end caps 3. Fixing the chip carrier 2 with the two detachable positioning end caps 3 facilitates the installation, maintenance and replacement of the LED light-emitting components, improves assembly efficiency, and enhances the modularity and maintainability of the structure.

[0027] In this specific embodiment, a positioning groove 31 is provided on the inner end face of the positioning end cover 3 for the chip carrier 2 to be embedded and installed. The two ends of the chip carrier 2 are respectively tightly fitted and embedded in the corresponding positioning groove 31. The positioning groove 31 on the inner side of the positioning end cover 3 and the ends of the chip carrier 2 are tightly fitted and embedded to ensure that the LED light-emitting component is stably suspended, avoiding loosening or displacement, while simplifying the assembly process and improving structural reliability.

[0028] In this specific embodiment, lamp tube connectors 4 are respectively provided at both ends of the external light-transmitting tube 1. The design of the lamp tube connectors 4 facilitates the quick installation, replacement, and circuit connection of the lamp tube, improving the versatility and applicability of the product and making it suitable for the installation needs of different lighting scenarios.

[0029] In this specific embodiment, the LED light-emitting component is centrally suspended inside the external light-transmitting tube 1. This positions the LED light source at the center of the tube, ensuring uniform 360° light radiation and avoiding uneven light distribution caused by proximity to the tube wall, thus optimizing the all-angle light emission effect.

[0030] In this specific embodiment, the chip carrier 2 is made of glass. Glass has high light transmittance, high temperature resistance, and good insulation properties, which can ensure sufficient light transmission, assist in heat dissipation, and avoid the light-blocking problem of traditional aluminum substrates, thereby improving overall light efficiency and reliability.

[0031] Example 2: The rest is the same as in Example 1, except that an inner light-transmitting tube 5 is suspended inside the outer light-transmitting tube 1. The LED light-emitting component is placed inside the inner light-transmitting tube 5, and the maximum outer diameter of the LED light-emitting component matches the inner diameter of the inner light-transmitting tube 5. The inner light-transmitting tube 5 serves as the mounting carrier for the LED light-emitting component, effectively limiting the radial vibration of the LED chip and preventing light source displacement or damage due to shaking during transportation or use, thus improving structural stability. Simultaneously, the inner light-transmitting tube 5 and the outer light-transmitting tube 1 form a double-layer light-transmitting structure, which optimizes the light diffusion effect.

[0032] In this specific embodiment, the two ends of the inner light-transmitting tube 5 are positioned and installed by two positioning end caps 3. By using the existing detachable positioning end caps 3 to fix the inner light-transmitting tube 5, dual positioning of the chip carrier 2 and the inner light-transmitting tube 5 can be achieved without additional structures, simplifying the assembly process and ensuring the relative position of the inner light-transmitting tube 5 and the outer light-transmitting tube 1 is stable, avoiding loosening caused by resonance.

[0033] In this specific embodiment, a positioning cavity 32 is provided on the inner end face of the positioning end cover 3 for inserting and installing the end of the inner light-transmitting tube 5. The two ends of the inner light-transmitting tube 5 are respectively embedded and installed in the corresponding positioning cavity 32. Through the tight embedding design of the positioning cavity 32, the inner light-transmitting tube 5 is firmly fixed, further suppressing the axial displacement and vibration of the LED light-emitting component, while maintaining a suspended state, which does not affect heat dissipation and omnidirectional light emission characteristics.

[0034] In this specific embodiment, the inner light-transmitting tube 5 and the outer light-transmitting tube 1 are coaxially arranged. The coaxial structure ensures that light passes through the double-layer tubes evenly, avoiding light path deviation or uneven brightness.
