Description

T5 LED light source

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 15, 2023, with application number 202321526648.3 and invention name “T5 lamp tube with LED light source”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application belongs to the field of lighting technology, and more specifically, relates to a T5 lamp tube with an LED light source. Background Art

[0003] Traditionally used fluorescent tubes are T8 and T5, with diameters of 1 inch (25.4mm) and 5 / 8 inch (16mm), respectively, and lengths of 60cm, 120cm, and 150cm. Structural forms include a single tube with a bracket (including ballast) and a multi-tube lamp panel (including ballast). With the rapid development of LED technology in the lighting industry, traditional fluorescent lamps have been almost completely replaced by LED tubes, and market competition is fierce.

[0004] LED tubes share the same dimensions and diameter as traditional fluorescent lamps. Materials include semi-aluminum with a semi-plastic shade, full-plastic shade, and glass shade, allowing for different options and configurations based on market demand.

[0005] Compared with T8 or larger diameter LED tubes, T5 LED tubes have a thinner diameter. However, the length of the LED tube does not shorten due to the thinner diameter. The thinner diameter will cause the bending rigidity of the entire tube to be seriously reduced. During long-term use, it will heat up, causing the tube to bend and deform, seriously affecting the service life of the tube. Technical issues

[0006] The purpose of the embodiments of the present application is to provide a T5 lamp tube with an LED light source to solve the technical problem in the prior art that after long-term use and heating, the T5 lamp tube itself is not sufficiently rigid, causing the lamp tube to bend and deform, thereby seriously shortening the service life of the lamp tube. Technical Solutions

[0007] To achieve the above-mentioned purpose, the technical solution adopted in this application is: to provide a T5 lamp tube with an LED light source, comprising: a glass lampshade; a base, the base being arranged on the inner wall surface of the glass lampshade, and the length of the base along the extension direction is consistent with the length of the glass lampshade along the extension direction; a lamp head, the lamp head being connected to the end of the glass lampshade; a lamp board, the lamp board being arranged in the glass lampshade and being limitedly connected to the base; a power supply assembly, the power supply assembly being arranged in the lamp head and being conductively connected to the lamp head and the light board respectively.

[0008] The beneficial effect of the T5 lamp tube of the LED light source provided by the present application is that: compared with the existing technology, the T5 lamp tube of the LED light source of the present application sets the base on the inner wall surface of the glass lampshade, and the length of the base along the extension direction is consistent with the length of the glass lampshade along the extension direction, which can provide strength support when the glass lampshade is bent and deformed, thereby avoiding the bending and deformation of the glass lampshade and extending the service life of the lamp tube; at the same time, the glass lampshade is used as the outer cover of the lamp tube. Since the glass itself has good thermosetting properties, the lamp tube is not easy to bend and deform after long-term use, further improving the rigidity of the lamp tube itself and extending the service life of the entire LED lamp tube.

[0009] In one embodiment, a reinforcement rib is provided on a side of the base facing away from the lamp panel, and the reinforcement rib is extended along the length direction of the glass lampshade.

[0010] In one embodiment, there are multiple reinforcing ribs, and the multiple reinforcing ribs are spaced apart along the width direction of the base, and a glue coating groove is formed between two adjacent reinforcing ribs.

[0011] In one embodiment, a glue layer for bonding the glass lampshade and the base is provided in the glue groove.

[0012] In one embodiment, a mounting groove is provided on a side of the base close to the light board, and the mounting groove is used to limit the position of the light board.

[0013] In one embodiment, a limiting portion is provided on the inner wall surface of the mounting groove, and the limiting portion is used to prevent the lamp board from being separated from the mounting groove toward a side away from the base.

[0014] In one embodiment, the base is an aluminum profile.

[0033] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0034] 1 to 3 , the LED light source T5 lamp provided in the embodiment of the present application will now be described. The LED light source T5 lamp includes a glass lampshade 10 , a base 20 , a lamp holder 30 , a lamp board 40 and a power supply assembly 50 .

[0035] The base 20 is arranged on the inner wall surface of the glass lampshade 10, and the length of the base 20 along the extension direction is consistent with the length of the glass lampshade 10 along the extension direction; the lamp head 30 is connected to the end of the glass lampshade 10; the lamp board 40 is arranged in the glass lampshade 10 and is limitedly connected to the base 20; the power supply component 50 is arranged in the lamp head 30 and is respectively conductively connected to the lamp head 30 and the lamp board 40.

[0036] For example, as shown in Figures 1 to 3, the glass lampshade 10 is cylindrical in structure. The glass lampshade 10 and the base 20 are both elongated, and the length of the base 20 is slightly shorter than that of the glass lampshade 10. The base 20 is fixed to the inner wall surface of the glass lampshade 10 by an adhesive material. Since the base 20 is generally made of lightweight metal and has good bending strength, by fixing the base 20 to the inner wall surface of the glass lampshade 10, the rigidity of the glass lampshade 10 can be enhanced, making it more difficult to bend and deform. The glass lampshade 10 is a hollow structure with open ends. By arranging the lamp head 30 at the end of the glass lampshade 10, it can prevent external objects from entering the glass lampshade 10. The lamp panel 40 generates a large amount of heat during operation. By mounting the lamp panel 40 on the base 20, some of the heat in the lamp panel 40 is transferred to the base 20, while also preventing the lamp panel 40 from shaking freely within the glass lampshade 10. The power supply assembly 50 is mainly used to provide power to the light board 40 .

[0037] The T5 lamp tube of the LED light source provided in the present application is compared with the prior art. The T5 lamp tube of the LED light source in the present application sets the base 20 on the inner wall surface of the glass lampshade 10, and the length of the base 20 along the extension direction is consistent with the length of the glass lampshade 10 along the extension direction. It can provide strength support when the glass lampshade 10 is bent and deformed, thereby avoiding the bending and deformation of the glass lampshade 10 and extending the service life of the lamp tube. At the same time, the glass lampshade 10 is used as the outer cover of the lamp tube. Since the glass itself has good thermosetting properties, the lamp tube is not easy to bend and deform after long-term use, further improving the rigidity of the LED lamp tube itself and extending the service life of the entire LED lamp tube.

[0038] In one embodiment of the present application, please refer to FIG. 2 and FIG. 3 , a reinforcement rib 21 is provided on a side of the base 20 facing away from the lamp board 40 , and the reinforcement rib 21 is extended along the length direction of the glass lampshade 10 .

[0039] Specifically, the reinforcing rib 21 is also a long strip structure, and the length of the reinforcing rib 21 along the extension direction is consistent with the length of the glass lampshade 10 along the extension direction. By protruding the reinforcing rib 21 on the outer surface of the base 20, the bending strength of the base 20 itself can be enhanced, thereby indirectly enhancing the bending strength of the glass lampshade 10 and further extending the service life of the lamp.

[0040] In one embodiment of the present application, please refer to Figures 2 and 3 together. There are multiple reinforcing ribs 21, and the multiple reinforcing ribs 21 are spaced apart along the width direction of the base 20, and a glue coating groove 22 is formed between two adjacent reinforcing ribs 21.

[0041] Specifically, there are four reinforcing ribs 21, and the shapes of the four reinforcing ribs 21 are not exactly the same. The two outermost reinforcing ribs 21 are provided with chamfered structures that match the shape of the inner wall of the glass lampshade 10. The four reinforcing ribs 21 are located on the side of the base 20 away from the lamp board 40, and the four reinforcing ribs 21 match the shape of the inner wall of the glass lampshade 10. A total of three glue grooves 22 are formed between the four reinforcing ribs 21. The glue grooves 22 extend along the length of the glass lampshade 10. By forming the glue grooves 22 inwardly on the base 20, the contact area between the base 20 and the glue can be increased, thereby increasing the bonding force between the base 20 and the glass lampshade 10 and preventing the base 20 and the glass lampshade 10 from separating.

[0042] In one embodiment of the present application, a glue layer for bonding the glass lampshade 10 and the base 20 is provided in the glue groove 22 .

[0043] Specifically, the openings at both ends of the T5 model glass lampshade 10 have limited diameters, making it difficult to limit the base 20 in the glass lampshade 10 through structure. By providing a glue layer between the glass lampshade 10 and the base 20, the glue protrusion can be placed on the glue groove 22 of the base 20 before assembly, and then the base 20 can be extended into the glass lampshade 10, and then the base 20 can be directly placed against the inner wall surface of the glass lampshade 10 to complete the installation, thereby improving assembly efficiency.

[0044] Furthermore, the adhesive layer itself has certain thermal conductivity and adhesion properties, which can fix the base 20 in the glass lampshade 10 while also dissipating the heat in the base 20. By providing the adhesive layer between the glass lampshade 10 and the base 20, it can effectively prevent the heat generated by the lamp board 40 during operation from being concentrated on the base 20 for a long time, thereby improving the heat dissipation performance inside the lamp tube.

[0045] In one embodiment of the present application, please refer to FIG. 3 , a mounting groove 23 is provided on one side of the base 20 close to the lamp board 40 , and the mounting groove 23 is used to limit the position of the lamp board 40 .

[0046] Specifically, the entire mounting groove 23 is U-shaped, and its length and width match those of the light board 40. The mounting groove 23 can limit the position of two opposite sides of the light board 40 in the width direction. By providing the mounting groove 23 on the base 20, the light board 40 can be effectively restrained within the glass lampshade 10, thereby preventing the light board 40 from moving freely within the glass lampshade 10.

[0047] In one embodiment of the present application, please refer to FIG. 3 , a limiting portion 24 is provided on the inner wall surface of the mounting groove 23 , and the limiting portion 24 is used to prevent the lamp board 40 from being separated from the mounting groove 23 toward the side away from the base 20 .

[0048] Specifically, the stopper 24 is positioned on the side of the light board 40 facing away from the reinforcing rib 21. The mounting groove 23 cooperates with the stopper 24 to limit the position of the light board 40 on opposite sides in the width direction and opposite sides in the thickness direction. Providing the stopper 24 on the mounting groove 23 further secures the light board 40 within the glass lampshade 10, preventing the light board 40 from separating from the base 20 in either the width direction or the thickness direction.

[0049] In one embodiment of the present application, please refer to FIG. 1 to FIG. 3 , the base 20 is made of aluminum profile.

[0050] Specifically, aluminum profiles have excellent thermal conductivity and are lighter than other commonly used metals for the same volume. Using aluminum profiles as the base 20 can more efficiently dissipate heat generated by the lamp panel 40, while also making the entire lamp tube lighter than other commonly used metals.

[0051] In one embodiment of the present application, please refer to Figure 2. The power supply component 50 includes a circuit board 51 and an electrical component 52. The electrical component 52 is arranged on the circuit board 51 and is conductively connected to the circuit board 51. A heat conductive sheet 53 for heat dissipation is attached to the circuit board 51.

[0052] Specifically, the electrical component 52 is arranged on one side of the circuit board 51, wherein there are multiple electrical components 52, and multiple electrical components 52 are highly concentrated on the circuit board 51, and each electrical component 52 will generate heat during operation. The circuit board 51 will also generate a large amount of heat during operation. The circuit board 51 will accumulate its own heat and the heat of multiple electrical components 52. The thermal conductive sheet 53 is made of a high thermal conductivity material and can efficiently absorb nearby heat and promptly conduct heat to surrounding high-temperature objects. By affixing the thermal conductive sheet 53 on the circuit board 51, the problem of the circuit board 51 overheating after a long period of operation can be avoided, the aging process of the power supply component 50 can be delayed, and the service life of the T5 lamp tube of the LED light source can be further extended.

[0053] In one embodiment of the present application, the outer peripheral side of the glass lampshade 10 is covered with a protective film for preventing breakage.

[0054] Specifically, the protective film's primary function is to prevent fragments from scattering freely in the surrounding area after the glass lampshade 10 shatters. The protective film possesses high adhesion, tensile strength, a high elongation of 160%, strong acid and alkali resistance, and maintains good physical properties even at high temperatures. At the same time, it maintains good light transmittance, ensuring that light can penetrate the interior of the lamp tube while maintaining explosion-proof performance. The explosion-proof performance of glass is achieved primarily through two aspects: First, by fully utilizing the adhesive layer on the protective film to decompose the impact force on the surface. Even if the glass shatters, the adhesive in the adhesive layer of the film works together to pull the glass fragments, preventing them from splashing, effectively protecting people and property. Second, through the unique micro-displacement of the protective film's interlayer sliding, the impact force that passes through the glass and acts on the safety film is mitigated, forming a unique impact resistance that effectively prevents glass shattering and injury caused by external impact. By providing a protective film on the outside of the glass lampshade 10, the safety performance of the entire LED lamp tube can be effectively improved.

[0055] In one embodiment of the present application, please refer to FIG. 2 , a positioning portion 31 is protruded from the lamp holder 30 , and the positioning portion 31 is used to position the end of the glass lampshade 10 .

[0056] Specifically, the lamp holder 30 has a housing cavity, and the power supply assembly 50 is disposed within the housing cavity. During assembly, the power supply assembly 50 is first electrically connected to the lamp panel 40. The lamp panel 40 is then inserted into the glass lampshade 10 and positioned on the base 20. At this point, the power supply assembly 50 is exposed at one end of the glass lampshade 10. Finally, the lamp holder 30 is sleeved onto the outer periphery of the power supply assembly 50, and the lamp holder 30 and the glass lampshade 10 are engaged and positioned together. By providing a positioning portion 31 on the inner wall surface of the lamp holder 30, it is possible to prevent the engagement position between the lamp holder 30 and the glass lampshade 10 from deviating from the preset position, thereby preventing the size of the entire LED lamp tube from deviating.

[0057] The above are merely preferred embodiments of the present application and only specifically describe the technical principles of the present application. These descriptions are intended only to explain the principles of the present application and should not be construed in any way as limiting the scope of protection of the present application.
