Description

Technical Field

[0001] The utility model belongs to the technical field of lamp tubes, and in particular relates to a heat dissipation lamp tube capable of concealing wires. Background Art

[0002] Existing LED tube lamps suffer from three common drawbacks: First, the traditional single-sided light-emitting structure results in insufficient lighting uniformity, making it difficult to meet the high-demand requirements of commercial lighting applications. Second, the light panels are often fixed with glue or screws, which is inefficient to install and prone to falling off. Third, the connecting wires between the tubes are exposed, which not only affects the appearance but also poses a safety hazard. Furthermore, the conventional lamp housing has a weak heat dissipation design, which can lead to accelerated light decay and shortened lifespan due to heat accumulation over long-term operation. Therefore, a tube structure that conceals cables, provides multi-directional uniform light, is easy to install, and provides efficient heat dissipation is urgently needed. Utility Model Content

[0003] (1) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the present invention is to provide a heat dissipation lamp tube with hidden wires, so as to solve the technical problems of existing LED lamp tubes such as poor single-sided luminous uniformity, low lamp board installation efficiency, unsightly exposed wires, and insufficient heat dissipation leading to accelerated light decay.

[0005] (2) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A heat dissipation lamp tube with concealed wires comprises: a lamp housing, an inner side wall of which is symmetrically provided with two clamping parts along the length direction; a lamp holder, arranged inside the lamp housing and corresponding to the light-emitting surface of the lamp housing, with first clamping grooves on both sides of the lamp holder engaged with the clamping parts, and bent to form multiple mounting surfaces facing the front and both sides of the light-emitting surface of the lamp housing, and second clamping grooves on both sides of each mounting surface; a lamp board, arranged on the corresponding mounting surface and with both sides snapped into the second clamping grooves; and a plug, which is fitted on both ends of the lamp housing and electrically connected to the lamp board through the wiring terminals arranged thereon; wherein the back side of the lamp housing is concave inward to form a hidden wire groove for the wires of adjacent lamp tubes to pass through, and a wire passing hole is provided on the plug at a position corresponding to the hidden wire groove.

[0008] The lamp holder and the lamp housing are connected by a clip-on structure - the first clip-on slot. This allows the lamp holder to be quickly positioned and installed inside the lamp housing. The multiple mounting surfaces formed by the bending of the lamp holder and the second clip-on slots on both sides allow the lamp panel to be fixed at multiple angles without the need for auxiliary tools, significantly improving assembly efficiency and ensuring mechanical stability. This comprehensively addresses the integrated needs of multi-directional, uniform lighting and efficient installation. Furthermore, the hidden wire trough and wire hole form a closed wiring channel, completely concealing the connecting wires between adjacent lamp tubes inside the tubes, eliminating the visual clutter and electric shock hazards caused by exposed wires, and enhancing product aesthetics and safety.

[0009] In some embodiments, a first heat dissipation fin is formed on the back side of the lamp holder along its length.

[0010] The first heat dissipation fin significantly increases the contact area between the lamp holder and the air, accelerating the diffusion of heat generated by the lamp panel during operation into the air, suppressing heat accumulation in the core area of ​​the light source, effectively delaying light decay and extending the life of the lamp panel.

[0011] In some embodiments, second heat dissipation fins are formed on the back and / or side surfaces of the lamp housing along the length thereof.

[0012] The second heat dissipation fin further expands the heat dissipation path on the outer surface of the lamp housing, forming a coordinated heat dissipation system with the lamp holder heat dissipation structure, enhancing the overall thermal management capability, and avoiding excessive local temperature rise of the lamp housing, which may lead to material aging or optical performance degradation.

[0013] In some embodiments, the inner surface of the light emitting surface of the lamp housing is provided with a diffuse reflection surface.

[0014] The diffuse reflective surface softly scatters direct light, eliminating the granularity and glare of the lamp beads, improving light uniformity and visual comfort. It is especially suitable for commercial and home environments that require soft lighting. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0024] The utility model provides a heat dissipation lamp tube with concealed wires, which is mainly composed of a lamp housing 1, a lamp holder 2, a lamp board and a plug 3. The lamp housing 1 is made of extruded aluminum alloy, and its inner side wall is integrally formed with two symmetrically distributed clamping parts 11 along the length direction. The clamping parts 11 can be cylindrical or dovetail groove structures. The lamp holder 2 is arranged inside the lamp housing 1, and is formed by bending an aluminum plate with a thickness of about 1.2 mm to form three mounting surfaces 21 facing the front and left and right sides of the light-emitting surface 15 of the lamp housing 1 (the bending angle of each surface is 120°); a first clamping groove 24 that engages with the clamping part 11 is provided on both sides of the lamp holder 2, and a second clamping groove 23 with a depth of about 2 mm is stamped on both sides of each mounting surface 21. The lamp board is a PCB substrate, and its two side edges are directly embedded in the second clamping groove 23 of the corresponding mounting surface 21 to achieve tool-free fixation. The plug 3 is made of flame-retardant PC plastic injection molding and is fitted over both ends of the lamp housing 1. The plug 3 is provided with a wiring terminal, one end of which is electrically connected to the wires of each lamp board and the other end is connected to the external power wire, thereby constructing a closed electrical cavity.

[0025] Furthermore, the back of the lamp housing 1 is recessed inward to form a full-length hidden wire groove 12. This groove has a U-shaped cross-section, is approximately 3mm deep and 5mm wide, and is formed integrally through an extrusion process. A wire hole 31 with a diameter of approximately 6mm is provided on the plug 3, corresponding to the location of the hidden wire groove 12. A rubber sealing ring (or silicone material) is embedded in the hole. This allows the wires between adjacent lamps to pass through the hole 31 and be completely hidden within the hidden wire groove 12, forming a closed wiring channel.

[0026] Specifically, when multiple lamps are used in series, a main conductor (including multiple branch wires) is used to connect the multiple lamps in series. The specific wiring is as follows:

[0027] The main conductor is led out from the power supply, with one branch electrically connected to the terminal block on the first lamp plug 3. The main conductor then extends through the first lamp's wire hole 31 and hidden wire slot 12 to the next lamp. Another branch is electrically connected to the terminal block on the next lamp plug 3, and so on until it reaches the terminal block on the last lamp. This ensures a seamless, fully exposed main conductor layout and electrical connectivity.

[0028] It's worth noting that the back of the lamp holder 2 is milled to form first heat dissipation fins 22 approximately 8 mm high, with a 3 mm spacing between the fins and parallel to the length of the lamp holder 2. Preferably, the fins and the lamp holder 2 are integrally formed from an aluminum alloy (thermal conductivity > 200 W / m·K), allowing heat from the lamp panel to be transferred to the fins through the mounting surface 21 for dissipation.

[0029] On this basis, second heat dissipation fins 13, approximately 5 mm in height, are formed on the back and / or sides of the lamp housing 1 through a cold forging process. Specifically, the fins are approximately 1.5 mm thick at the base and taper to 0.8 mm at the top to optimize heat conduction. Specifically, the fins are arranged in a parallel array. This increases the heat dissipation area while maintaining the lamp's bending strength.

[0030] Finally, a diffuse reflection surface 14 with a concave-convex structure is formed on the inner surface of the light emitting surface 15 of the lamp housing 1. This design causes multiple scattering of direct light, eliminating LED particle spots while maintaining a light transmittance of more than 85%.

[0031] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
