Description

Technical Field

[0001] This application relates to the field of lighting technology, and more particularly to an adapter and a lighting assembly using the adapter. Background Technology

[0002] Fluorescent lamps have long been widely used in the lighting field. The core components of a fluorescent lamp are a glass tube and a filament. The inside of the tube is coated with phosphor, and the filament is coated with a substance that emits electrons. A core is used to fix the filament and ensure a seal with the glass tube. The tube is filled with inert gas and mercury vapor. Traditional fluorescent lamp manufacturing processes include: fabricating the glass tube; uniformly coating the inner cavity of the tube with phosphor; inserting the core to hold the filament; coating the filament with an electron-emitting paste; sealing the core and tube to form a fixed-opening cavity; removing impurities from the tube and filling it with an appropriate amount of inert gas and mercury; separating the excess material from the tube body; and finally assembling the lamp holder to form the final product. In fluorescent lamps, the lamp holder is generally made of metal, and the lamp holder is bonded to the tube using solder putty. The curing temperature of the solder putty used in fluorescent lamps is generally 180-200℃, and the baking time is about 2 minutes. On the production line, welding putty is first placed into the metal lamp holder, then the lamp holder is fitted onto the end of the lamp tube and heated with a flame to the curing temperature of the welding putty, causing it to expand significantly, thus achieving the effect of curing after cooling. The advantage of using welding putty to connect the lamp holder to the lamp tube is its extremely low cost. In fluorescent lamps, the reason why it is possible to use flame heating to 180-200℃ to cure the welding putty is because this temperature will not damage other components in the fluorescent lamp tube. The industrial production line for fluorescent lamps is now relatively mature, but due to intense competition, its profit margin has been significantly squeezed.

[0003] LED, or Light Emitting Diode, is a solid-state semiconductor device that directly converts electricity into light. LED energy-saving lamps use high-brightness white LEDs as the light source, offering high luminous efficiency, low power consumption, long lifespan, easy control, maintenance-free operation, and are safe and environmentally friendly. As a new generation of solid-state cold light source, they provide soft, vibrant, and richly colored light with low loss and energy consumption, making them suitable for long-term lighting in homes, shopping malls, banks, hospitals, hotels, restaurants, and other public places. The flicker-free DC power provides excellent eye protection, making them an ideal choice for desk lamps and flashlights. LED tube lamps generally consist of a tube, a light panel containing the light source within the tube, and lamp holders at both ends of the tube. The lamp holders contain power supply components, and the light source and power supply components are electrically connected through the light panel.

[0004] LED lights are a type of lighting fixture that has developed rapidly in recent years. Their light-emitting element is a semiconductor light-emitting diode. Current technology requires an LED light with a simple structure, few parts, high lighting efficiency, convenient soldering, fast curing speed, adaptability to industrial assembly line production, and high yield.

[0005] However, in the existing technology, the lamp holders at both ends of the lamp tube are connected to adapters. The adapters are used to fix the lamps in place. However, the existing adapters can only be connected to the lamp holders at one end. When different lamp holders are needed, another adapter is required to form the lamp assembly. This is costly and has limited applicability.

[0006] Lighting components are indispensable tools in people's daily lives. Currently, with the increasing complexity and diversity of lighting component applications, higher demands are being placed on their functionality. Specifically, most existing lighting components are only suitable for single-power, single-color-temperature applications, failing to meet the lighting environment requirements of different usage scenarios. Furthermore, the dimensions of the assembly components corresponding to lighting components vary, making it difficult to guarantee the compatibility and reliability of connections between lighting components of the same size and assembly components of different sizes, thus affecting the practicality and reliability of the lighting components.

[0007] Therefore, there is an urgent need for an adapter that can be plugged into lamp holders at both ends, in order to create more functional lighting components while reducing the cost of use. Utility Model Content

[0078] This embodiment provides a lighting assembly, see reference. Figure 1 , 4As shown, the lighting assembly includes a tube 1 (also referred to as a lamp tube 1), a lamp holder (a lamp holder 2 and a lamp holder 3), and an adapter 4. The tube 1 contains a light-emitting element, and the lamp holders are located at the ends of the tube 1, i.e., both ends of the tube 1. Each lamp holder includes a connection structure conforming to a first connection protocol. In one embodiment, the connection structure can be a conductive pin, such as a first conductive pin or a second conductive pin. Each lamp holder includes a receiving space, and at least one lamp holder contains a power supply component, which is at least partially located within the receiving space. The power supply component includes at least one circuit board, and is electrically connected to the light-emitting element inside the tube 1 (e.g., connected to the light-emitting element via the circuit board). A connection structure located at least at one end of the lighting assembly is used to connect / transmit external signals to the power supply component (further connecting / transmitting signals to the light-emitting element). The first lamp head 2 is fixed to one end of the tube body 1. A circuit board 21 is installed inside the first lamp head 2, and the circuit board 21 is electrically connected to the light-emitting element. The first lamp head 2 has a protruding first conductive pin 22 electrically connected to the light-emitting element. An adjustment component is provided on the first lamp head 2, which can move relative to the first lamp head 2 to allow the circuit board 21 (which can also be considered a power supply component) to adjust the output power and output color temperature of the light-emitting element. For example, the color temperature and power output can be achieved by controlling the external signal provided by the lamp holder assembly. The second lamp head 3 is fixed to the other end of the tube body 1. The second lamp head 3 has a protruding second conductive pin 31 electrically connected to the light-emitting element, i.e., a conductive pin structure protrudes from the lamp head. In other words, the lamp heads (first lamp head 2 and / or second lamp head 3) are provided with an adjustment component, which can move relative to the lamp head. The output power and output color temperature of the light-emitting element can be controlled by the adjustment component. In one embodiment, the lamp assembly may further include two adapter devices 4, which are detachably mounted on the first lamp head 2 and the second lamp head 3, respectively. The adapter device 4 includes a housing 41 (see reference...). Figure 7 , Figure 11 As shown, the adapter 4 and the electrical connector are connected. One end of the electrical connector can be electrically connected to a conductive pin (first conductive pin 22 or second conductive pin 31), and the other end can extend to the surface of the housing 41. That is, the adapter 4 is connected and conductive to the connection structure of the lamp holder, and the connection between the two conforms to a second agreement. At least one end of the lamp assembly is provided with the adapter 4, that is, at least one of the lamp holders (the end away from the tube body) is provided with the adapter 4. The adapter 4 is used to connect to the lamp holder assembly for providing external signals. That is, the adapter 4 is connected and conductive to the lamp holder assembly, and transmits the external signal provided by the lamp holder assembly to the lamp holder connected to the adapter 4. That is, the external signal transmitted by the adapter is received through the connection structure (conductive pin) on the lamp holder and then transmitted to the power supply assembly (or the light-emitting assembly). Specifically, the external signal provided by the lamp holder assembly can be transmitted to the connection device of the lamp holder through the adapter, and then transmitted to the power supply assembly through the connection device of the lamp holder, and then transmitted to the light-emitting component through the power supply assembly (circuit board or components set on the circuit board).

[0079] In this embodiment, the adjustment component is movable relative to the first lamp head 2, allowing the circuit board 21 to adjust the output power and / or color temperature of the light-emitting element. This enables the adjustment of the power and / or color temperature of the lamp assembly during illumination, further meeting the lighting environment requirements of different usage scenarios. Furthermore, the adapter 4 is detachably mounted on the first lamp head 2 and the second lamp head 3. When the adapter 4 is mounted on the first lamp head 2, one end of the electrical connector can connect to the first conductive pin 22, and the other end can extend to the surface of the housing 41. The adapter 4 allows the circuit between the first conductive pin 22 and the external conductive assembly component to be connected. When the adapter 4 is mounted on the second lamp head 3, one end of the electrical connector can connect to the second conductive pin 31, and the other end can extend to the surface of the housing 41. The adapter 4 allows the circuit between the second conductive pin 31 and the external conductive assembly component to be connected. Through the conversion function of the adapter 4, the connection compatibility and reliability between the lamp assembly structure of different sizes can be further guaranteed, as well as the connection compatibility and reliability between the lamp assembly and the external lamp holder can be improved, thereby further enhancing the overall functionality of the lamp assembly.

The first adjustment lever 211 can be connected to a power control element, thereby adjusting the output power of the light-emitting element on the circuit board 21 by adjusting the first adjustment block 23. The second adjustment block 24 is connected to the second adjustment lever 212, and the second adjustment block 24 can slide relative to the first lamp head 2, causing the second adjustment lever 212 to slide relative to the circuit board 21. The second adjustment lever 212 can be connected to a color temperature control element, thereby adjusting the output color temperature of the light-emitting element on the circuit board 21 by adjusting the second adjustment block 24.

The first lamp head 2 is provided with a second sliding groove 203, and the bottom end of the second sliding groove 203 is provided with a second sliding hole 204. The second adjusting block 24 includes a second sliding part 241 and a second connecting part 242 fixed to the end of the second sliding part 241.

The provision of the first friction pattern 2311 and the second friction pattern 2411 can increase the friction between the operator's hand and the first sliding part 231 and the second sliding part 241, ensuring that the first sliding part 231 and the second sliding part 241 can be effectively pushed, thereby reliably realizing the adjustment of output power and / or output color temperature.

[0084] Furthermore, continue to refer to Figures 2 to 6 As shown, a first clamping and fixing groove 233 is provided at the end of the first connecting part 232 away from the first sliding part 231. The two side walls of the first clamping and fixing groove 233 can clamp and fix the first adjusting lever 211. The two sides of the first clamping and fixing groove 233 are in close contact with the end face of the corresponding side of the first adjusting lever 211, that is, there is an interference fit between the first clamping and fixing groove 233 and the first adjusting lever 211, thereby ensuring reliable fixation between the first adjusting block 23 and the first adjusting lever 211.

[0085] The second connecting portion 242 has a second clamping and fixing groove 243 at the end away from the second sliding portion 241. The two side walls of the second clamping and fixing groove 243 can clamp and fix the second adjusting lever 212. The two sides of the second clamping and fixing groove 243 are in close contact with the end face of the corresponding side of the second adjusting lever 212, that is, there is an interference fit between the second clamping and fixing groove 243 and the second adjusting lever 212, thereby ensuring reliable fixation between the second adjusting block 24 and the second adjusting lever 212.

[0086] Furthermore, each of the two opposite openings of the first clamping and fixing groove 233 is provided with a first guide slope 2331. The two first guide slopes 2331 are arranged one-to-one and extend inclined from the outside to the inside of the opening of the first clamping and fixing groove 233 towards each other. By providing two first guide slopes 2331, a guiding effect can be provided when the first clamping and fixing groove 233 clamps the first adjusting lever 211, so that the first clamping and fixing groove 233 can clamp the first adjusting lever 211 more quickly and accurately.

[0087] The second clamping and fixing groove 243 has two corresponding second guide slopes 2431 on its two opposite sides. The two second guide slopes 2431 extend from the outside to the inside of the groove of the second clamping and fixing groove 243, moving closer to each other. By providing two second guide slopes 2431, a guiding effect can be provided when the second clamping and fixing groove 243 clamps the second adjusting lever 212, so that the second clamping and fixing groove 243 can clamp the second adjusting lever 212 more quickly and accurately.

[0088] Furthermore, the first sliding portion 231 is provided with first engaging members 2312 on both sides of the first sliding elongated hole 202 in the width direction. The first engaging member 2312 includes a first elastic connecting portion 23121 and a first engaging end 23122. The first elastic connecting portion 23121 is connected to the lower end of the first sliding portion 231, and the first engaging end 23122 is disposed at the end of the first elastic connecting portion 23121. The first elastic connecting portion 23121 passes through the first sliding elongated groove 201 and the first sliding elongated hole 202, so that the first engaging end 23122 can be slidably engaged with the inner wall of the corresponding side of the first sliding elongated hole 202. This arrangement can prevent the first adjusting block 23 from falling out of the first sliding elongated hole 202 during the sliding process relative to the first sliding elongated hole 202, ensuring that the first adjusting block 23 can slide reliably.

[0089] Furthermore, the second sliding portion 241 is provided with second locking connectors 2412 on both sides of the second sliding elongated hole 204 in the width direction. Each second locking connector 2412 includes a second elastic connecting portion 24121 and a second locking end 24122. The second elastic connecting portion 24121 is connected to the lower end of the second sliding portion 241, and the second locking end 24122 is located at the end of the second elastic connecting portion 24121. The second elastic connecting portion 24121 passes through the second sliding elongated groove 203 and the second sliding elongated hole 204, allowing the second locking end 24122 to be slidably locked onto the inner wall of the corresponding side of the second sliding elongated hole 204. This arrangement prevents the second adjusting block 24 from dislodging from the second sliding elongated hole 204 during sliding relative to it, ensuring reliable sliding of the second adjusting block 24.

Optionally, multiple first reinforcing ribs 4061 are provided, and the multiple first reinforcing ribs 4061 are arranged circumferentially along the first protrusion.

[0102] In this embodiment, the number of first reinforcing ribs 4061 is set to two.

[0103] Furthermore, a first through hole 4051 is provided at the bottom of the first sinking trough 405. The first through hole 4051 can provide some heat dissipation to the inside of the housing 41 of the adapter 4, and can also reduce the weight of the overall structure of the housing 41.

[0104] Optionally, the number, distribution position, and shape of the first through holes 4051 can be adaptively adjusted according to factors such as heat dissipation requirements and lightweight requirements. In this embodiment, the number of first through holes 4051 is set to multiple, and the multiple first through holes 4051 are distributed at intervals along the circumference of the housing 41. The shape of the first through holes 4051 can be set to a strip shape, or it can be set to a circle, square, triangle, arc, or other shapes.

[0105] The adapter 4 described in the above embodiment achieves contact and electrical conduction between the light emitter inside the tube 1 and the external conductive assembly component through the first conductive sheet 42 and the conductive end cap 43 at the end away from the tube body 1.

[0106] As another alternative embodiment, refer to Figures 11 to 14 As shown, the housing 41 has two second receiving grooves 403 spaced apart on one end face facing the tube 1.

[0107] Furthermore, when the first conductive pin 22 or the second conductive pin 31 is inserted into the second receiving groove 403, the first side of the third conductive part 441 is tightly pressed against the inner peripheral wall of the second receiving groove 403, and the second side of the third conductive part 441 is tightly pressed against the first conductive pin 22 or the second conductive pin 31. This ensures both reliable fixation of the third conductive part 441 and close contact between the third conductive part 441 and the first conductive pin 22 or the second conductive pin 31, thus ensuring electrical conductivity.

[0108] Furthermore, a second guide rib 4031 is provided on the inner peripheral wall of the second receiving groove 403, and the second guide rib 4031 extends along the depth direction of the receiving groove 403. The second guide rib 4031 is configured to guide the end of the third conductive part 441 in the extension direction within the second receiving groove 403 after bending, and can compress and fix the third conductive part 441.

[0109] The number of second guide limiting ribs 4031 is set to two, and the bent end of the third conductive part 441 is fixed between the two second guide limiting ribs 4031, thereby enabling both sides of the third conductive part 441 to be guided.

[0119] Optionally, the number, distribution position, and shape of the second through holes 4081 can be adaptively adjusted according to factors such as heat dissipation requirements and lightweight requirements. In this embodiment, the number of second through holes 4081 is set to multiple, and the multiple second through holes 4081 are distributed at intervals along the circumference of the housing 41. The shape of the second through holes 4081 can be set to a strip shape, or it can be set to a circle, square, triangle, arc, or other shapes.

[0120] Reference Figures 15 to 17 The diagram below shows a switching device in another embodiment of this application. Figures 15 to 17As shown, the adapter 4 includes a housing 41, which has a first end 4002 and a second end 4003 opposite to each other. The first end 4002 and the second end 4003 are located on different sides of the housing 41, that is, on both sides of the housing 41 respectively. The adapter 4 also includes an electrical connector, which may include a first electrical connector and a second electrical connector. The first electrical connector 45 is disposed at the first end 4002 of the adapter 4, and the first electrical connector 45 is provided with a second receiving groove 403. The number of second receiving grooves is at least one (or more). In one embodiment of this application, two second receiving grooves 403 may be provided and are symmetrically arranged along the central axis of the adapter 4. The housing 41 has a tubular structure, with the first end 4002 and the second end 4003 recessed towards the middle of the housing 41, forming a first receiving cavity 4004 and a second receiving cavity 4005, respectively. A second electrical connector 46 is disposed at the second end 4003 of the adapter 4, meaning at least a portion of the second electrical connector 46 is housed in the second receiving cavity 4005. The second electrical connector 46 is provided with a first receiving groove 401. Two first receiving grooves 401 can be provided and symmetrically arranged along the central axis of the adapter 400. It should be noted that the second receiving groove 403 and the first receiving groove 401 are staggered in the circumferential direction of the adapter 4. In this embodiment, the second receiving groove 403 and the first protrusion 411 are located on the same side, and the first receiving groove 401 is located on the opposite side. The second receiving groove 403 is a through hole, and one end of the first receiving groove 401 is closed, while the other end is open.

[0121] At least a portion of a second conductive sheet 44 is disposed in the second receiving groove 403. The second conductive sheet 44 extends from one side of the first electrical connector 45 through the adapter 4 to the second end 4003 of the adapter 4. At least a portion of the first conductive sheet 42 is disposed in the first receiving groove 401.

[0122] A first conductive piece 42 extends from one side of the second electrical connector 46 through the adapter 4 to the first end 4002 of the adapter 4. In this embodiment, by providing a first electrical connector 45 and a second electrical connector 46 that can mate with different lamp holders at both ends of the adapter 4, diverse needs are met, usage costs are reduced, and production management is facilitated. That is, in this embodiment, the adapter 4 can achieve electrical conduction with the lamp holder 2 through the first electrical connector 45 or the second electrical connector 46, resulting in different shapes for the outermost electrical connector of the lamp. That is, both the first and second electrical connectors can achieve electrical connection with the conductive pins on the lamp body, or in other words, the first conductive pin 22 and / or the second conductive pin 31 can be electrically connected to the first receiving groove 401 and / or the second receiving groove 403, i.e., the conductive pin is inserted into the receiving groove. In other words, both the first electrical connector 45 and the second electrical connector 46 can be connected and conductive to the connecting structure on the lamp holder, or to the lamp base assembly. When the first electrical connector 45 is connected to the connecting structure on the lamp holder (i.e., when the first electrical connector 45 points towards the tube body 1), the corresponding second electrical connector 46 points away from the tube body 1 and can be connected and conductive to the lamp base assembly. Conversely, when the second electrical connector 46 is connected to the connecting structure on the lamp holder (i.e., when the second electrical connector 46 points towards the tube body 1), the corresponding first electrical connector 45 points away from the tube body 1. Alternatively, when the lamp assembly is in use, if one of the first electrical connector 45 or the second electrical connector 46 is connected to the lamp holder, the corresponding other electrical connector is connected to the lamp base assembly; that is, if one of the first electrical connector 45 and the second electrical connector 46 points towards the tube body 1, the corresponding other electrical connector points away from the tube body 1.

[0123] When the lamp holder is connected and energized by the first electrical connector 45 or the second electrical connector 46 on the adapter 4 through the connection structure, the second electrical connector 46 or the first electrical connector 45 on the adapter 4 is connected and energized by the lamp holder assembly, and the external signals provided by the lamp holder assembly are sequentially transmitted to the adapter, the connection structure and the power supply assembly.

[0124] Furthermore, such as Figure 15 and Figure 16 As shown, the adapter 4 has a cylindrical structure. The first end 4002 of the adapter 4 is provided with a first receiving cavity 4005, and the second end 4003 of the adapter 4 is provided with a second receiving cavity 4005. In this embodiment, both the first receiving cavity 4005 and the second receiving cavity 4005 are receiving grooves. At least a portion of the first electrical connector 45 is disposed in the first receiving cavity 4005, and at least a portion of the second electrical connector 46 is disposed in the second receiving cavity 4005.

[0125] Furthermore, such as Figure 16 and Figure 17As shown, the first electrical connector 45 includes a first base 450, a first protrusion 411, and a conductive end cap 43. In this embodiment, the inner diameter of the conductive end cap 43 is, for example, 7.56 mm, and the outer diameter of the first protrusion 411 is, for example, 7.23 mm. The conductive end cap 43 can directly and tightly cover the first protrusion 411 without the need for additional adhesive coating. The first base 450 is cross-shaped, and the edges of the first base 450 have a smooth transition structure. The first base 450 is connected to the inner wall of the first receiving cavity 4005 through several connecting ribs. The first base 450 is connected to... The first end 4002 of the adapter 4 has a first protrusion 411 connected to the end of the first base 450 away from the adapter 4. A conductive end cap 43 is sleeved on the first protrusion 411 and electrically connected to the first conductive sheet 42. Part or all of the first base 450 is located inside the first receiving cavity 4005, and part or all of the first protrusion 411 is located inside the first receiving cavity 4005 or outside the first receiving cavity 4005. In this embodiment, the entire first base 450 is located inside the first receiving cavity 4005, and the entire first protrusion 411 is located outside the first receiving cavity 4005. In some other embodiments of this application, the first conductive sheet 42 has a certain elasticity and protrudes slightly outward along the radial direction of the first protrusion 411, such that the first conductive sheet 42 on the first protrusion 411 slightly exceeds its inner diameter in the radial direction of the conductive end cap 43. During assembly, the conductive end cap 43 and the first conductive sheet 42 on the first protrusion 411 are in an interference fit. The conductive end cap 43 presses the first conductive sheet 42 to cause it to undergo elastic deformation and form a restoring force from the inner wall of the conductive end cap 43 outward, so that the first conductive sheet 42 abuts against and is pressed tightly against the inner wall of the conductive end cap 43, thereby achieving a tight connection between the conductive end cap 43 and the first protrusion 411 without the need for other additional fixing structures or fixing materials.

[0126] Furthermore, such as Figure 15 As shown, the second electrical connector 46 includes a second base 460 and a snap-fit ​​connector 470. The second base 460 is cross-shaped and has a smooth transition structure at its edge. The second base 460 is connected to the inner wall of the second receiving cavity 4005 by several connecting ribs. The second base 460 is connected to the second end 4003 of the adapter 4. The snap-fit ​​connector 470 is connected to the end of the second base 460 away from the adapter 4. Part or all of the second base 460 is located inside the second receiving cavity 4005, and part or all of the snap-fit ​​connector 470 is located inside or outside the second receiving cavity 4005. In this embodiment, all or part of the second base 460 is located inside the second receiving cavity 4005, and all or part of the snap-fit ​​connector 470 is located outside the second receiving cavity 4005.

[0127] Furthermore, such as Figure 15 and Figure 16As shown, the second receiving groove 403 extends from the first base 450 to the second electrical connector 46, and the second conductive sheet 44 extends from one end of the second receiving groove 403 to the other end of the second receiving groove 403. The two ends of the second conductive sheet 44 are respectively snapped onto the first base 450 and the snap-fit ​​connector 470. The second conductive sheet 44 is made of conductive material or metal material, such as copper, silver, gold, aluminum, iron, etc.

[0128] Furthermore, such as Figure 15 and Figure 16 As shown, a through hole 402 is provided in the middle of the first protrusion 411 and the snap-fit ​​connector 470. One end of the first conductive piece 42 is snapped onto the second base 460, and the other end of the first conductive piece 42 is snapped onto the first protrusion 411. A groove 480 is provided on the first protrusion 411. The first conductive piece 42 extends from the groove 480 into the first through hole 402 and the first receiving groove 401 in sequence. The first conductive piece 42 is made of metal, such as copper, which can improve the electrical connection effect.

[0129] The present invention also provides a lamp, including the above-mentioned adapter 4. The lamp may further include a tube body 1, two lamp heads and a power supply assembly. The lamp heads include a first lamp head 2 and a second lamp head 3 (not shown). The number of power supply assemblies is at least one, that is, a power supply assembly is provided in at least one lamp head.

[0130] Furthermore, such as Figures 18 to 21 As shown, one end of the first lamp head 2 (or the second lamp head 3, not shown) has a receiving space. In one embodiment, the receiving space may be a receiving cavity 207. The power supply component is disposed in the receiving cavity 207 corresponding to the first lamp head 2 (or the second lamp head 3, not shown), or at least part of the power supply component is disposed in the receiving cavity 207. The tube body 1 is connected to lamp holders at both ends, namely a first lamp holder 2 and a second lamp holder 3, and is electrically connected to the power supply components inside the first lamp holder 2 and / or the second lamp holder 3. The first lamp holder 2 is provided with a slot 206 that communicates with or is recessed into the accommodating cavity 207 at the end away from the accommodating cavity 207. The slot 206 can be engaged with the first protrusion 411 or the conductive end cap 43 (clamping connector 470). The first lamp holder 2 is also provided with a first conductive needle 22 at the end where the slot 206 is provided. The first conductive needle 22 is electrically connected to the power supply components. The first conductive needle 22 consists of two hollow conductive needles, and the positions of the two hollow conductive needles correspond to the second accommodating groove 403 and the first accommodating groove 401.

[0131] Figure 18 and Figure 19 The diagram shows the structure after using the same adapter to cooperate with the first lamp holder 2, so as to adapt to the R17D model lamp holder and the Fa8 model lamp holder, thereby reducing the cost of use. The lamp holder is not shown in the figure.

[0132] Figure 19 When the slot 206 is engaged with the first electrical connector 45, that is, when the first protrusion 411 is inserted into the slot 206, the first conductive pin 22 is inserted into the second receiving slot 403 and electrically connected to the second conductive piece 44. The connector 470 can be inserted into the R17D model lamp holder, and the part of the second conductive piece 44 located in the connector 470 is electrically connected to the connector of the R17D model lamp holder.

[0133] Figure 18 In the process, when the slot 206 is engaged with the second electrical connector 46, that is, when the connector 470 is inserted into the slot 206, the first conductive pin 22 is inserted into the first receiving groove 401 and electrically connected to the first conductive sheet 42. After the conductive end cap 43 is inserted into the Fa8 model lamp holder, the conductive end cap 43 is electrically connected to the connector in the Fa8 model lamp holder.

[0134] As described above, at least one end of the lamp head includes a connecting structure (i.e., a conductive pin, such as a first conductive pin or a second conductive pin). This connecting structure conforms to a first connection protocol. The at least one connecting structure can be fixed to the adapter device in the manner described above (such as a plug-in connection) to achieve electrical connection and signal transmission. The adapter device can be fixed to different types of lamp holder assemblies via a snap-fit ​​connector 470 or a conductive end cap 43, and fixed to the lamp holder assembly. The two conform to a second connection protocol, enabling electrical conduction and signal transmission. The adapter device connects to the lamp holder assembly and transmits the external signal provided by the lamp holder to the at least one connecting structure. This connecting structure then transmits the external signal to the power supply assembly. The power supply assembly transmits the external signal to the light-emitting element or other electronic components through components such as a circuit board, thereby enabling the external signal to control the lamp assembly.

[0135] In this embodiment, an adhesive film may be covered on the inner or outer circumferential surface of the tube 1, thereby isolating the outside and inside of the tube 1 after it breaks, thus preventing fragments from scattering.

[0136] Furthermore, such as Figure 21 As shown, a number of limiting strips 205 are provided on the inner side wall of the accommodating cavity 207. The limiting strips 205 are distributed at equal intervals or at different intervals on the inner side wall of the accommodating cavity 207. After the tube body 1 is inserted, the end abuts against the limiting strip 205. The tube body 1 and the lamp holder (first lamp holder 2, second lamp holder 3) can be fixedly connected by hot melt adhesive, or by fastening, welding or other methods.

[0137] In this embodiment, the material of the lamp holders (first lamp holder 2, second lamp holder 3) is not limited to plastic, ceramic, etc., as long as it is not a good conductor of electricity under normal conditions. Furthermore, the hot melt adhesive is a composition containing a material that is essentially solder paste, preferably composed of: phenolic resin 2127#, shellac, rosin, calcite powder, zinc oxide, ethanol, etc. In this embodiment, rosin is a tackifier, soluble in ethanol but insoluble in water. This hot melt adhesive can change its physical state and expand significantly under high-temperature heating conditions, achieving a curing effect. Combined with the adhesiveness of the material itself, this allows the first lamp holder 2 to make tight contact with the tube body 1, facilitating automated production of LED straight tube lights. In this embodiment, the hot melt adhesive expands and flows after high-temperature heating, and then cures upon cooling. When the hot melt adhesive is heated from room temperature to a temperature of 200 to 250 degrees Celsius, its volume will expand to 1 to 1.3 times its original size. Of course, the selection of hot melt adhesive components in this invention is not limited to this; components that cure after being heated to a predetermined temperature can also be used. Since the hot melt adhesive of this invention will not experience a decrease in reliability due to the high-temperature environment created by heat-generating components such as power supply components, it can prevent a reduction in the bonding performance between the tube body 1 and the first lamp holder 2 during lamp installation, thereby improving long-term reliability.

[0138] refer to Figure 18 , Figure 19 In some embodiments of this application, the length of the first lamp holder 2 can be set to ensure that the overall length of the lamp fixture meets certain specifications after the adapter is assembled. For example, in some embodiments, the first lamp holder 2 is designed to be recessed to provide installation space for the corresponding adapter length. In other embodiments, the length of the tube body 1 can be adjusted to ensure that the length of the lamp fixture after the adapter is installed is within a certain range. That is, if the length of the adapter, lamp holder, and lamp tube assembly is set as d, then the length range of d needs to be set within the minimum and maximum allowable values ​​for this type of lamp tube. For example, for a certain T8 lamp tube, the minimum allowable length without an adapter is 601.2 mm, and the maximum allowable length is 604.0 mm. Therefore, when setting the adapter, the overall length d still needs to be set within the range of 601.2 mm to 604.0 mm (including the range of the two endpoints) so that the lamp tube (lamp fixture) with the adapter can still be installed in a standard lamp holder. Specific dimensions and specifications should refer to the American ANSI, European IEC, and Japanese 210924-AC lamp size standards. The design should ensure that the overall length of the luminaire with the adapter conforms to their installation standards. In some embodiments of this application, different connecting parts may be located on opposite end faces of the adapter 4. In other embodiments, different connecting parts may be located on one end face of the adapter 4, but at different angles, achieving conductivity through different installation angles between the adapter and the lamp holder.

[0139] In some other embodiments of this application, the electrical conductive element (electrical connector) provided on the adapter has a certain amount of extension and retraction, that is, the electrical conductive element can extend and retract relative to the adapter; for example Figure 19 The first protrusion 411 indicates that the adapter 4 moves a certain distance under pressure control, and returns to its initial position when the pressure disappears. The extension range can be 0mm to 100mm.

[0140] The description of the first lamp holder 2 in this article can also be used for the second lamp holder 3. That is, in some embodiments, the first lamp holder 2 and the second lamp holder 3 can be equivalently replaced.

[0141] Obviously, the above embodiments of this application are merely examples for clear illustration and are not intended to limit the implementation of this application. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the scope of protection of this application. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
