Description

[0001] This utility model application was submitted to the China Patent Office on November 10, 2022, with application number 202222997142.2, and the utility model name is a divisional application of "A LED lamp". Technical Field

[0002] The present application belongs to the technical field of LED lighting devices, and specifically relates to an LED lamp. Background Art

[0003] LED lighting has many advantages such as long service life, small size, energy saving and power saving, etc., so it is widely used in the market, gradually replacing the existing incandescent lamps and fluorescent lamps.

[0004] LED lamps in the prior art generally have different lengths according to different powers. The higher the power, the longer the LED lamp. Too long a length may cause the LED lamp to have the following disadvantages:

[0005] 1. Compared with short LED lights, long LED lights have a larger bending moment when bent and broken. They may break when subjected to a smaller external force. Therefore, they are more likely to be damaged by external forces during transportation.

[0006] 2. Assuming that the light-emitting body of the LED lamp is divided into a first light-emitting body and a second light-emitting body of shorter length, since no LED is arranged at the connection between the first light-emitting body and the second light-emitting body, a dark area will be formed at the connection, affecting the light-emitting effect.

[0007] 3. Assuming there is an LED lamp, electrical connection and structural connection must be achieved when the first light-emitting body and the second light-emitting body are connected. If the electrical connection is completed before the structural connection, the electrical connection may become loose during the structural connection, resulting in failure of the electrical connection. If the structural connection is performed before the electrical connection, in order to avoid electric shock to the user, the electrical connection is generally located inside the LED lamp. After the structural connection is completed, it is generally not easy to perform connection operations on the inside of the LED lamp.

[0008] 4. When the first light-emitting body is connected to the second light-emitting body, if the two light-emitting bodies are detachably connected, electric shock may easily occur when the splicing state of the first light-emitting body and the second light-emitting body is accidentally released when the power is on.

[0009] In summary, in view of the shortcomings and defects of LED lamps in the prior art, how to design LED lamps to reduce damage during transportation, improve light output effect, and improve assembly efficiency is a technical problem that urgently needs to be solved by technical personnel in this field.

[0069] In order to facilitate the understanding of the present application, the present application will be described more comprehensively with reference to the relevant drawings below. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described below. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thoroughly and comprehensively understood. The directions such as "first", "second", "third", "axial direction", "above", "below", etc. in the following text are all for the purpose of more clearly indicating the structural position relationship and are not limitations on the present application. In the present application, the "vertical", "horizontal" and "parallel" are defined as: including the situation of ±30% based on the standard definition. For example, vertical usually refers to an angle of 90 degrees relative to the reference line, but in the present application, vertical refers to a situation within 60 to 120 degrees.

[0070] The present application provides an LED lamp, which includes a light-emitting area and a dark area. The light-emitting area is an area where light is transmitted, and the dark area is an area where no light is transmitted. The light-emitting area is located between two adjacent dark areas. Specifically, the light-emitting area includes a first light-emitting area and a second light-emitting area, and the dark area includes a first dark area, a second dark area, and a third dark area. The first light-emitting area is located between the first dark area and the third dark area, and the second light-emitting area is located between the second dark area and the third dark area. In this embodiment, the length of the light-emitting area accounts for at least 70%, 75%, 80%, 85%, 90% or 91% of the total length of the LED lamp to ensure that the LED lamp has a sufficient light-emitting area.

[0071] See also Figures 1 to 17 The LED lamp comprises a first luminous body 1 (also referred to as a first component) and a second luminous body 2 (also referred to as a second component) connected to the first luminous body 1. The first luminous body is non-detachably spliced ​​with the second luminous body. Since the splicing state of the first luminous body and the second luminous body will not be released, the charged components in the LED lamp will not be exposed, and thus electric shock will not occur. The first luminous body 1 and the second luminous body 2 extend in the length direction of the LED lamp, and the two are coaxially or substantially coaxially arranged. Since the length of the LED lamp is long, when the two ends of the LED lamp are subjected to force, the LED lamp is easy to break due to its long length and large bending moment, so it is more likely to be damaged by external force during transportation. The LED lamp is split into two independent first luminous bodies 1 and second luminous bodies 2. The first luminous body 1 and the second luminous body 2 can be packaged independently. When the two ends of each LED luminous body are subjected to force, the bending moment is relatively small, and it is not easy to be damaged during transportation. After receiving the LED lamp, the user can dock the first luminous body 1 and the second luminous body 2 before installing and using them. The installation process is simple. When the first luminous body 1 and the second luminous body 2 are docked, they are in an unpowered state, and there is no risk of electric shock. The first luminous body 1 and the second luminous body 2 are both made of light-transmitting materials, such as glass, plastic, etc., and are in a straight tube structure. In order to further improve the light-emitting effect, the surfaces of the first luminous body 1 and the second luminous body 2 can be selectively coated with a diffusion layer (not shown) to reduce the visual graininess, for example, a diffusion coating is coated on the inner surface of the first luminous body 1 or the second luminous body 2, or a diffusion sleeve film is coated on the outer surface of the first luminous body 1 or the second luminous body 2.

[0072] The LED lamp includes a connecting unit, a main body area and two lamp heads, the two lamp heads are respectively connected to the main body area, and the connecting unit covers a part of the main body area. A part of the main body area forms the above-mentioned light-emitting area, the two lamp heads and the connecting unit form the above-mentioned dark area, the two lamp heads respectively form the first dark area and the second dark area, and the connecting unit forms the third dark area. In the length direction of the LED lamp, the length of the connecting unit is not greater than 0.05, 0.04, 0.03, 0.02 or 0.015 times the total length of the LED lamp. In one embodiment, the length of the connecting unit is not less than 20 mm. In some embodiments, the length of the connecting unit is not greater than 35, 40, 45 or 50 mm. On the one hand, since there is no light source at the connecting unit and the connecting unit is in the middle of the main body area, the connecting unit will form a dark area. The longer the length of the connecting unit, the larger the range of the dark area, which affects the aesthetics of the LED lamp; on the other hand, since the connecting unit needs to be designed for structural connection, a certain length must be guaranteed for structural connection.

[0073] Figures 1 to 3 , FIG. 4A to FIG. 4D and Figure 5A and Figure 5D This is a schematic diagram of the structure of the first embodiment of this application, see Figures 1 to 3 , FIG. 4A to FIG. 4D and Figure 5A and Figure 5D The main body area includes a first main body area 14 (also referred to as a first light-emitting portion) of the first light-emitting body 1 and a second main body area 24 (also referred to as a second light-emitting portion) of the second light-emitting body 2. A portion of the first main body area 14 forms the first light-emitting area described above, and a portion of the second main body area 24 forms the second light-emitting area described above. The first main body area 14 includes a first light board 141 and a first light-emitting unit 142 located on the first light board 141. The second main body area 24 includes a second light board 241 and a second light-emitting unit 242 located on the second light board 241. The first light-emitting unit 142 and the second light-emitting unit 242 respectively include a plurality of LED chips 11 (as can be seen in FIG. Figure 3), the distance between any LED chip 11 in the first main body area 14 and any LED chip 11 in the second main body area 24 is greater than the length of the connecting unit. Among them, the first light-emitting unit 142 and the first light board 141 can be summarized as the first light source, and the second light-emitting unit 242 and the second light board 241 can be summarized as the second light source. Since the LED chip 11 has a certain light-emitting angle, and there are LED chips 11 adjacent to the connecting unit in both the first main body area 141 and the second main body area 241, the light emitted by the LED chip 11 adjacent to the connecting unit in the first light-emitting unit 142 is partially refracted toward the connecting unit (when the connecting unit is transparent), and similarly, the light emitted by the LED chip 11 adjacent to the connecting unit in the second light-emitting unit 242 is partially refracted toward the connecting unit after passing through the second light-emitting body 2, thereby avoiding the formation of a third dark area in the connecting unit. The beam angles of the LED chip S1 and the LED chip S2 adjacent to the connecting unit are α and β respectively. α and β can be the same or different angles. The maximum distance between the light-emitting surface of LED chip S1 and LED chip S2 and the first light-emitting body 1 and the second light-emitting body 2 is H. In practice, the height of LED chip S1 and LED chip S2 can be ignored, and H can be the height of the first light-emitting body or the second light-emitting body. In one embodiment, the area between LED chip S1 and LED chip S2 emits light, that is, the connecting unit does not form a third dark area, and the length of the connecting unit is less than (H*tan(0.5α)+H*tan(0.5β)).

[0074] The lamp holder includes a first lamp holder 12 of a first light-emitting body 1 and a second lamp holder 22 of a second light-emitting body 2. The first lamp holder 12 forms the first dark area described above, and the second lamp holder 22 forms the second dark area described above. The connecting unit includes a first connecting portion 13 and a second connecting portion 23. The first connecting portion 13 is connected to the second connecting portion 23. The first lamp holder 12 is connected to the first main body area 14, and the second lamp holder 22 is connected to the second main body area 24. The LED lamp realizes structural connection and electrical connection at the same time through the first connecting portion 13 and the second connecting portion 23, and the installation process is simple and the assembly efficiency is high.

[0075] The first connection part 13 and the second connection part 23 are structurally connected and electrically connected respectively through the mounting unit and the electrical connection unit. The mounting unit is arranged around the electrical connection unit. On the one hand, it is not easy to directly contact the electrical connection unit, thereby reducing the risk of electric shock to the user due to contact with the electrical connection unit; on the other hand, the mounting unit protects the electrical connection unit to prevent the electrical connection unit from being damaged by external force. The mounting unit can achieve structural connection between the first connection part 13 and the second connection part 23 by means of snap, bonding, magnetic attraction, etc. The electrical connection unit can achieve electrical connection between the first connection part 13 and the second connection part 23 by means of male plug and female plug, so that the first light board 141 and the second light board 241 are electrically connected.

[0076] The first connection portion 13 covers a portion of the first main body area 14, and the first connection portion 13 includes a first side wall 131, and the first side wall 131 faces the second connection portion 23. The second connection portion 23 covers a portion of the second main body area 24, and the second connection portion 23 includes a second side wall 231, and the second side wall 231 faces the first connection portion 13. When the first connection portion 13 is connected to the second connection portion 23, the first side wall 131 is in contact with the second side wall 231 (the contact here includes the case where the distance between the first side wall 131 and the second side wall 231 is less than 1 mm).

[0077] The mounting unit includes at least one connecting hole 132 (also called a first combining unit) on the first side wall 131 and at least one fixing portion 232 (also called a second combining unit) on the second side wall 231. The fixing portion 232 is opposite to the connecting hole 132. The fixing portion 232 passes through the connecting hole 132 to achieve the structural connection between the first light-emitting body 1 and the second light-emitting body 2. Specifically, the connecting hole 132 has a first accommodation space R1 (see Figure 4D ) and the second accommodating space R2 connected to the first accommodating space R1, the protrusion 233 on the fixing portion 232 first enters the first accommodating space R1 and then stays in the second accommodating space R2. Since the maximum radial distance (also called the aperture) of the first accommodating space R1 is smaller than the minimum radial distance (also called the aperture) of the second accommodating space, the fixing portion 232 is not easy to escape from the connecting hole 132, thereby realizing a stable connection between the first light-emitting body 1 and the second light-emitting body 2.

[0078] In one embodiment, there is a first distance H1 between the protrusion 233 of the fixing portion 232 and the second side wall 231 (eg, Figure 5D As shown), the first connection hole 132 has a second distance H2 (also called buckle depth, as shown in FIG. Figure 4D As shown in FIG. 1 , the first distance H1 is substantially equal to or slightly greater than the second distance H2. Thus, when the first connection portion 13 and the second connection portion 23 are engaged with each other via the connection hole 132 and the fixing portion 232, the first side wall 131 and the second side wall 231 can substantially fit together or there is only a small gap between them. In one embodiment, the second distance H2 can be the wall thickness of the first side wall 131, and the first distance H1 of the fixing portion 232 is designed accordingly, so that the first distance H1 is substantially equal to or slightly greater than the second distance H2.

[0079] In addition, from Figure 5B It can be seen that the length of the fixing portion 232 (the length along the axial direction from the second side wall 231 to the first side wall 131) is longer than the length of the second conductive needle 235. Therefore, the fixing portion can protect the second conductive needle 235 in the length direction (the axial direction of the second light emitting body 2). Figure 5BIn the embodiment, the second connection portion 23 has four fixing portions 232 and is located at the periphery of the second conductive needle 235 and the second hole 234. Therefore, the fixing portions 232 protect the second conductive needle 235 and the second hole 234 in the lateral direction (radial direction of the second light-emitting body). In addition, the spacing between two adjacent fixing portions 232 can be appropriately designed considering the bonding strength and the protection effect (please refer to other embodiments of the present application).

[0080] The electrical connection unit includes a first hole 133 and a first conductive needle 134 (also called a first electrical connection portion) on the first side wall 131, and a second hole 234 (also called a second electrical connection portion) and a second conductive needle 235 on the second side wall 231. The second conductive needle 235 is inserted into one of the first holes 133, and the first conductive needle 134 is inserted into one of the second holes 234, so as to realize the electrical connection between the first light-emitting body 1 and the second light-emitting body 2. The other of the first holes 133 is arranged corresponding to the first conductive needle 134, and the other of the second holes 234 is arranged corresponding to the second conductive needle 235, that is, in the height direction of the first light-emitting body 1 (i.e. Figure 4D In the vertical direction of the viewing angle), the other first hole 133 and the first conductive needle 134 are at the same horizontal height; in the height direction of the second light-emitting body 2, the other second hole 234 and the second conductive needle 235 are at the same horizontal height. After the first light-emitting body 1 and the second light-emitting body 2 are electrically connected, the electrical connection path between the first conductive needle 134 and the second conductive needle 235 is a straight line (corresponding to the first conductive member 135 and the second conductive member 236, which will be explained later), the wiring distance is short, and the electrical connection is stable. If only the first conductive needle 134 is set on the first side wall 131, in order to realize the electrical connection between the first light-emitting body 1 and the second light-emitting body 2, the wire in the second light-emitting body 2 needs to be welded in the first connecting part 13, which is prone to cold welding, affecting the stability of the electrical connection between the first light-emitting body 1 and the second light-emitting body 2; secondly, if manual welding is used, production efficiency is affected. The present application respectively arranges a first conductive needle 134 and a second conductive needle 235 on the first side wall 131 and the second side wall 231, and the wires in the first light-emitting body 1 and the wires in the second light-emitting body 2 are riveted into the first conductive needle 134 and the second conductive needle 235, respectively, so that the electrical connection is stable and the process is simple. In one embodiment, the first hole 133 is a conductive hole, and the first hole 133 and the first conductive needle 134 are electrically connected. The second hole 234 is a conductive hole and the second hole 234 and the second conductive needle 235 are electrically connected, so that the second conductive needle 235 is inserted into one of the first holes 133, and the first conductive needle 134 is inserted into one of the second holes 234, thereby realizing the electrical connection between the first light-emitting body 1 and the second light-emitting body 2. In this embodiment, the first hole 133 and the second hole 234 can be made of conductive materials to make them have conductive functions.

[0081] The electrical connection unit also includes a conductive member, which mainly plays an electrical connection role, and any conductive material can be used as the material of the conductive member. The conductive member includes a first conductive member 135 located on the first connection portion 13 and a second conductive member 236 located on the second connection portion 23. The first conductive member 135 and the second conductive member 236 are connected to the first conductive needle 134 and the second conductive needle 235 respectively. The first conductive member 135 extends along the long axis of the first hole 133, and the second conductive member 236 extends along the long axis of the second hole 234. When the first light-emitting body 1 is connected to the second light-emitting body 2, the first conductive member 135 contacts the second conductive needle 235, and the second conductive member 236 contacts the first conductive needle 134, thereby realizing the electrical connection between the first conductive needle 134 and the second conductive needle 235. Since the first conductive member 135 and the second conductive member 236 are used to doubly guarantee the electrical connection between the first conductive needle 134 and the second conductive needle 235, even if the first conductive member 135 or the second conductive member 236 has poor contact, it will not affect the normal lighting of the LED lamp.

[0082] FIG. 6A to FIG. 6C For a structural diagram of the second embodiment of the LED lamp of this application, please refer to FIG. 6A to FIG. 6C , FIG. 7A to FIG. 7B , FIG. 8A to FIG. 8B and Fig.9A and Fig. 9B The LED lamp includes a connecting unit, a main body area and two lamp holders. The two lamp holders are respectively connected to the main body area. The connecting unit covers a part of the main body area. A part of the main body area forms the above-mentioned light-emitting area. The two lamp holders and the connecting unit form the above-mentioned dark area. The two lamp holders can form the first dark area and the second dark area respectively. The connecting unit and a part of the main body area together form the third dark area. The main body area includes a first main body area 14 and a second main body area 24. Even if there is a gap between the first main body area 14 and the second main body area 24, since the locking unit 3 of the connecting unit covers a part of the first main body area 14 and a part of the second main body area 24, it will not affect the aesthetics of the LED lamp.

[0083] The connection unit realizes structural connection and electrical connection respectively through the installation unit and the electrical connection unit. The installation unit is arranged around the electrical connection unit. On the one hand, it is not easy to directly contact the electrical connection unit, thereby reducing the risk of electric shock to the user due to contact with the electrical connection unit; on the other hand, the installation unit protects the electrical connection unit to prevent the electrical connection unit from being damaged by external force during transportation or installation. The installation unit can realize the structural connection between the first main body area 14 and the locking unit 3, and the locking unit 3 and the second main body area 24 by means of snap, bonding, magnetic attraction, etc. The electrical connection unit can realize the electrical connection between the first main body area 14 and the second main body area 24 by means of male plug and female plug, that is, the first light board 141 and the second light board 241 are electrically connected.

[0084] The first connecting portion 13 includes a first side wall 131 and a first fixing portion 151 connected to the first side wall 131 (see FIG. Figure 7B , also called the first combining unit), the first fixing portion 151 extends from the first side wall 131 toward the length direction of the first main body area 14 (or the length direction of the LED lamp), and the first fixing portion 151 can be arranged around the first side wall 131. The second connecting portion 23 includes a second side wall 231 and a second fixing portion 251 connected to the second side wall 231 (see Figure 8B , also called a second combining unit), the second fixing portion 251 extends from the second side wall 231 toward the length direction of the second main body area 24 (or the length direction of the LED lamp), and the second fixing portion 251 can be arranged around the second side wall 231.

[0085] The mounting unit includes a third fixing buckle 301 and a fourth fixing buckle 302 (the third and fourth fixing buckles 301, 302 may be collectively referred to as third combining units) disposed on the locking unit 3. The third fixing buckle 301 and the fourth fixing buckle 302 are respectively located at two ends of the locking unit 3. When the first light-emitting body 1 and the second light-emitting body 2 are connected through the locking unit 3, the first side wall 131 and the second side wall 231 are close to each other, and the first fixing portion 151 and the second fixing portion 251 are respectively snapped into the third fixing buckle 301 and the fourth fixing buckle 302 (i.e., the two third combining units are respectively snapped into the first combining unit and the second combining unit), thereby realizing the structural connection between the first light-emitting body 1 and the second light-emitting body 2. In some embodiments, the spacing between the first side wall 131 and the second side wall 231 is not greater than 5 mm. If the spacing between the first side wall 131 and the second side wall 231 is too large, the length of the locking unit 3 becomes longer accordingly, the dark area increases, and the lighting effect of the LED lamp is affected. In addition, the production cost is also increased accordingly.

[0086] Figure 7B and 8B In the embodiment, the first fixing portion 151 is adjacent to the first side wall 131, the second fixing portion 251 is adjacent to the second side wall, and the third fixing buckle 301 and the fourth fixing buckle 302 are arranged corresponding to the first fixing portion 151 and the second fixing portion 251. Therefore, during installation, the first light-emitting body 1 can be first inserted into one end of the locking unit 3 so that the first fixing portion 151 and the third fixing buckle 301 are buckled, and then the second light-emitting body 2 can be inserted into the other end of the locking unit 3 so that the second fixing portion 251 and the fourth fixing buckle 302 are buckled. In this way, the first connecting portion 13 and the second connecting portion 23 can be connected. In one embodiment, the first fixing portion 151 is located at the other end of the outer surface of the first connecting portion 13 away from the first side wall 131 (such as Figure 7B The second fixing portion 251 is located at the other end of the outer surface of the second connecting portion 23 away from the second side wall 231 (eg Figure 8BThe third fixing buckle 301 and the fourth fixing buckle 302 are arranged corresponding to the first fixing portion 151 and the second fixing portion 251. In this way, when the locking unit 3 is buckled with the first connecting portion 13 and the second connecting portion 23, the locking unit 3 covers the first connecting portion 13 and the second connecting portion 23 to play a protective role. Figure 7B and 8B In the embodiment, the number of the first fixing portion 151, the second fixing portion 251, the third fixing buckle 301 and the fourth fixing buckle 302 are two respectively, but the present invention is not limited thereto. The number can also be four and they are respectively distributed on the circumference, and the distribution method can be equidistant or unequally distributed.

[0087] The electrical connection unit includes a first conductive pin 134 disposed on the first side wall 131, a second conductive pin 235 disposed on the second side wall 231, and a third hole 303 (also referred to as a third electrical connection portion) disposed on the locking unit 3. The third hole 303 is located between the third fixing buckle 301 and the fourth fixing buckle 302. The number of the first conductive pins 134 is the same as the number of the second conductive pins 235. Each first conductive pin 134 has a corresponding second conductive pin 235, that is, the first conductive pin 134 and the second conductive pin 235 are arranged in the same manner. The first conductive pin 134 and the second conductive pin 235 are first inserted into the third hole 303 respectively, and then the first conductive pin 134 and the second conductive pin 235 are in contact (directly or indirectly). For indirect contact, for example, a conductive member (to be described later) is disposed in the third hole 303, and the first conductive pin 134 and the second conductive pin 235 are in contact with the conductive member respectively, thereby realizing the electrical connection between the first light-emitting body 1 and the second light-emitting body 2. In the length direction of the first light-emitting body 1, the length direction of the second light-emitting body 2 or the length direction of the LED lamp, the corresponding first conductive needle 134 and the second conductive needle 235 are on the same straight line (coaxially arranged), and the electrical connection route between the first conductive needle 134 and the second conductive needle 235 is a straight line, the wiring distance is short, and the electrical connection is more stable.

[0088] FIG. 10A to FIG. 10C For a structural diagram of the third embodiment of the LED lamp of this application, please refer to FIG. 10A to FIG. 10C , FIG. 11A to FIG. 11B , FIG. 12A to FIG. 12B and Fig.13 , which is different from the second embodiment in that the locking unit 3 is connected to the first main body area 14 and the second main body area 24 in different ways.

[0089] The first connecting portion 13 includes a first side wall 131 and a first fixing portion 151 connected to the first side wall 131 (see FIG. Fig. 11B), the first fixing portion 151 extends from the first side wall 131 toward the length direction of the first main body area 14 (or the length direction of the LED lamp), and the first fixing portion 151 can be arranged around the first side wall 131. The second connecting portion 23 includes a second side wall 231, and a second fixing buckle 252 (see Fig. 12B ), relative to the first conductive pin 231, the second fixing buckle 252 is away from the central axis of the LED lamp. In the length direction of the second main body area 24 (or the length direction of the LED lamp), the second main body area 24 is further provided with a bearing portion 253, which connects the second side wall 231 and the second fixing portion 251.

[0090] The locking unit 3 includes an inner surface and an outer surface opposite to each other, and the mounting unit includes a third fixing buckle 301 and a third fixing portion 304 (see FIG. Fig. 10C and Fig.13 ), when the first luminous body 1 is connected to the second luminous body 2, the first main body area 14 enters the inner surface of the locking unit 3 from the first direction, the first fixing portion 151 is inserted into the third fixing buckle 301, and the second main body area 24 enters the interior of the locking unit 3 from the second direction, the second fixing portion 251 moves to a position opposite to the third fixing portion 304, and the second fixing buckle 252 is inserted into the second hole 152 located on the first side wall 131. A portion of the bearing portion 253 contacts the first fixing portion 151. The second fixing portion 251 is connected to the third fixing portion 304, and the connection method can be, for example, threaded connection, and the first direction is opposite to the second direction. Another portion of the bearing portion 253 forms an accommodating space with the third fixing buckle 301, and a portion of the first fixing portion 151 is located in the accommodating space. Since the moving position of the first fixing portion 151 is limited by the accommodating space, the connection strength between the locking unit 3 and the first main body area 14, and the locking unit 3 and the second main body area 24 can be guaranteed. In addition, when the first fixing portion 151 is connected to the third fixing buckle 301, since there is a gap between two adjacent first fixing portions 151, when the first fixing portion 151 is subjected to radial force, a portion of the first fixing portion 151 can be offset toward the central axis of the LED lamp, thereby being more easily inserted into the third fixing buckle 301.

[0091] Please refer to Fig.13 and FIG. 18A to FIG. 18B A plurality of recess groups are provided on the outer surface of the locking unit 3, each recess group includes a plurality of recesses 305, and the recesses 305 extend along the length direction of the locking unit 3. The recesses 305 can increase the friction between the installer's hand and the locking unit 3, and when the locking unit 3 is rotated, it is convenient for the operation of connecting the locking unit 3 with the second main body area.

[0092] Please refer to FIG. 10A to FIG. 10C , FIG. 11A to FIG. 11B and FIG. 12A to FIG. 12BThe electrical connection unit includes a first conductive part 101 connected to the first lamp board 141, a first hole 133 on the first side wall 131, and a second conductive part 102. The first conductive part 101 is connected to the second conductive part 102, and the second conductive part 102 extends from the first conductive part 101 along the first hole 133 to the first side wall 131. The electrical connection unit also includes a second conductive needle 235 located on the second side wall 231. When the first light-emitting body 1 is electrically connected to the second light-emitting body 2, the second conductive needle 235 is inserted into the first hole 133 and contacts the first conductive part 101 and the second conductive part 102. By setting the first conductive part 101 and the second conductive part 102, the second conductive needle 235 can ensure the electrical connection between the first light-emitting body 1 and the second light-emitting body 2 as long as it contacts the first conductive part 101 or the second conductive part 102, and the electrical connection of the LED lamp is stable.

[0093] Please refer to Fig. 10C , 11B , 12B, the second fixing buckle 252 of the second side wall 231 has a first distance H1, and the second hole 152 of the first side wall 131 has a second distance H2 (shown in the figure). In this embodiment, the first distance H1 is greater than the second distance H2. Therefore, when assembling the first light-emitting body 1 and the second light-emitting body 2, the second hole 152 of the first connecting portion 13 and the second fixing buckle 252 of the second connecting portion 23 are first buckled to obtain a substantial combination. At this time, there may be a slight gap between the first side wall 131 and the second side wall 231. Then, the third fixing portion 304 of the locking unit 3 is locked to the second fixing portion 251 of the second connecting portion 23, and the third fixing buckle 301 of the locking unit 3 is pressed against the first fixing portion 151 of the first connecting portion 13, so that the first connecting portion 13 and the second connecting portion 23 are locked (i.e., the gap between the first side wall 131 and the second side wall 231 is eliminated).

[0094] FIG. 14A to FIG. 14C This is a schematic diagram of the structure of the fourth embodiment of the LED lamp of the present application. The LED lamp includes a connecting unit, a main body area and two lamp holders. The two lamp holders are respectively connected to the main body area. The locking unit covers a part of the main body area. A part of the main body area forms the above-mentioned luminous area. The two lamp holders and the locking unit form the above-mentioned dark area. The two lamp holders can form the first dark area and the second dark area respectively. The locking unit and a part of the main body area together form the third dark area. The main body area includes a first main body area 14 and a second main body area 24. Even if there is a gap between the first main body area 14 and the second main body area 24, since the locking unit 3 of the connecting unit covers a part of the first main body area 14 and a part of the second main body area 24, it will not affect the aesthetics of the LED lamp.

[0095] The lamp holder includes a first lamp holder 12 matched with the first light-emitting body 1 and a second lamp holder 22 matched with the second light-emitting body 2. The first lamp holder 12 forms the first dark area described above, and the second lamp holder 22 forms the second dark area described above. The first main body area 14 is connected to the first lamp holder 12, and the second main body area 24 is connected to the second lamp holder 22. The weight per unit length of the first dark area or the second dark area is greater than the weight per unit length of the third dark area. Since the power module of the LED lamp is installed on the lamp holder (the first lamp holder 12 and / or the second lamp holder 22), the two ends of the LED lamp are heavier. In addition, the middle part of the LED lamp is the connection position of the first light-emitting body 1 and the second light-emitting body 2. When the middle part is lighter, the first light-emitting body 1 is not easy to fall due to weight after being connected to the second light-emitting body 2. In some embodiments, the weight of the third dark area is not greater than 0.5 times the weight of the entire LED lamp (the total weight of the connecting part + the main body area + the two lamp holders). In some embodiments, the weight per unit length of the first dark area or the second dark area is greater than the weight per unit length of the first main body area 14 or the second main body area 24. The weight per unit length here refers to the weight of a certain area of ​​the LED lamp divided by the length of that area.

[0096] The connection unit realizes structural connection and electrical connection respectively through the mounting unit and the electrical connection unit, and the electrical connection unit is arranged around the mounting unit. The electronic components (such as conductive pins) in the electrical connection unit can be arranged in a larger area, and the creepage distance (described later) between the two electronic components is larger, and high-voltage electric shock is not likely to occur. In this embodiment, the creepage distance between adjacent conductive pins can reach 1.2 mm.

[0097] Please refer to FIG. 15A to FIG. 15B , FIG. 16A to FIG. 16B and Fig.17, the first connection part 13 includes a first side wall 131, and the second connection part 23 includes a second side wall 231. The electrical connection unit includes a first hole 133 and a first conductive needle 134 on the first side wall 131, and a second hole 234 and a second conductive needle 235 on the second side wall 231. The second conductive needle 235 is inserted into the first hole 133, and the first conductive needle 134 is inserted into the second hole 234, so as to realize the electrical connection between the first light-emitting body 1 and the second light-emitting body 2. The first hole 133 is arranged corresponding to the first conductive needle 134, and the second hole 234 is arranged corresponding to the second conductive needle 235, that is, on a circumference of the first side wall 131, the first hole 133 and the first conductive needle 134 are both located on or approximately on the same arc; on a circumference of the second side wall 231, the second hole 234 and the second conductive needle 235 are both located on or approximately on the same arc. After the first light-emitting body 1 and the second light-emitting body 2 are electrically connected, the electrical connection path between the first conductive needle 134 and the second conductive needle 235 is a straight line (corresponding to the first conductive member 135 and the second conductive member 236, which will be explained later), the wiring distance is short, and the electrical connection is stable. If only the first conductive needle 134 is set on the first side wall 131, in order to realize the electrical connection between the first light-emitting body 1 and the second light-emitting body 2, the wire in the second light-emitting body 2 needs to be welded in the second hole 234, which is prone to cold welding, affecting the stability of the electrical connection between the first light-emitting body 1 and the second light-emitting body 2; secondly, if manual welding is used, it affects the production efficiency. The present application respectively sets the first conductive needle 134 and the second conductive needle 235 on the first side wall 131 and the second side wall 231, and the wire in the first light-emitting body 1 and the wire in the second light-emitting body 2 are riveted in the first conductive needle 134 and the second conductive needle 235, respectively, so that the electrical connection is stable and the process is simple.

[0098] The electrical connection unit also includes a conductive member, which mainly plays an electrical connection role, and any conductive material can be used as the material of the conductive member. The conductive member includes a first conductive member 135 and a second conductive member 236, and the first conductive member 135 and the second conductive member 236 are connected to the first conductive needle 134 and the second conductive needle 235 respectively. The first conductive member 135 extends along the circumference of the first side wall 131 to the first hole 133, and the second conductive member 236 extends along the circumference of the second side wall 231 to the second hole 234. When the first light-emitting body 1 is connected to the second light-emitting body 2, the first conductive member 135 contacts the second conductive needle 235, and the second conductive member 236 contacts the first conductive needle 134, thereby realizing the electrical connection between the first conductive needle 134 and the second conductive needle 235. Since the first conductive member 135 and the second conductive member 236 are used to doubly guarantee the electrical connection between the first conductive needle 134 and the second conductive needle 235, even if the first conductive member 135 or the second conductive member 236 has poor contact, it will not affect the normal lighting of the LED lamp.

[0099] Please refer to Fig.17 , the first conductive needle 134 includes a first conductive needle a1, a first conductive needle a2, a first conductive needle a3, ..., a first conductive needle an (n is an integer), and the second conductive needle 235 includes a second conductive needle b1, a second conductive needle b2, a second conductive needle b3, ..., a second conductive needle bm (m is an integer), the first conductive needle a1, the first conductive needle a2, the first conductive needle a3, ..., the first conductive needle an are arranged on (or approximately located at) the same circumference, the second conductive needle b1, the second conductive needle b2, the second conductive needle b3, ..., the second conductive needle bm are arranged on (or approximately located at) the same circumference, and the connecting line of the first conductive needle a1 and the second conductive needle b1 is connected to the first conductive needle an (n≠1) and The connecting lines of the second conductive pins bm (m≠1) are not parallel. In this embodiment, the first conductive pins 134 include the first conductive pins a1, a first conductive pin a2, a first conductive pin a3, a first conductive pin a4 and a first conductive pin a5. The second conductive pins 235 include the second conductive pins b1, b2, b3, b4 and b5. The first conductive pins a1, a2, a3, a4 and a5 are arranged on (or approximately located at) the same circumference. The second conductive pins b1, b2, b3, b4 and b5 are arranged on (or approximately located at) the same circumference. After the first light-emitting body 1 is connected to the second light-emitting body 2, the connection line between the first conductive needle a1 and the second conductive needle b1 is not parallel to the connection line between the first conductive needle an (n≠1) and the second conductive needle bm (m≠1). When the LED lamp has more functions such as color temperature adjustment, the number of the first conductive needle 134 and the second conductive needle 235 will increase accordingly, and the distance between the first conductive needle an and the second conductive needle bm-1 (n=m) will be shortened accordingly.

[0100] In one embodiment, the number of the first conductive needles is equal to the number of the second conductive needles, and both are provided in 5 groups.

[0101] The mounting unit includes a first fixing hole 136 located on the first side wall 131 and a second fixing buckle 252 located on the second side wall 231. The first conductive needle 134 is arranged around the first fixing hole 136, and the second conductive needle 235 is arranged around the second fixing buckle 252. When the first light-emitting body 1 is connected to the second light-emitting body 2, the second fixing buckle 252 is inserted into the first fixing hole 136, thereby realizing the structural connection between the first light-emitting body 1 and the second light-emitting body 2. Fig. 15B and Fig. 16BIt can be seen that the cross-sections of the second fixing buckle 252 and the first fixing hole 136 are directional (the first fixing hole 136 has a protrusion at the bottom center, and the second fixing buckle 252 has a depression corresponding to the protrusion). The protrusion and the depression play a fool-proof role when the first connecting portion 13 and the second connecting portion 23 are combined, so that the first conductive needle, the second conductive needle, the first hole 133 and the second hole 234 can be correctly electrically connected.

[0102] Please refer to FIG. 14A to FIG. 14C and FIG. 18A to FIG. 18B The locking unit 3 includes an inner surface and an outer surface that are opposite to each other, and the mounting unit also includes a third fixing portion 304 located on the inner surface of the locking unit 3. When the first light-emitting body 1 is connected to the second light-emitting body 2, the first main body area 14 enters the inner surface of the locking unit 3 from the first direction (the first lamp holder 12 first enters the inner surface of the locking unit 3 and then passes through the locking unit 3), the second main body area 24 enters the inner surface of the locking unit 3 from the first direction, and the second fixing portion 251 moves to a position opposite to the third fixing portion 304. The second fixing portion 251 is connected to the third fixing portion 304. Part 304, the connection method can be, for example, threaded connection, the first connection part 13 and the second connection part 23 are respectively provided with a first limiting part 137 and a second limiting part 237, when the locking unit 3 is connected to the first light-emitting body 1 and the second light-emitting body 2, one end of the locking unit 3 is in contact with the first limiting part 137 (partial contact or full contact), and the other end of the locking unit 3 is in contact with the second limiting part 237 (partial contact or full contact), thereby limiting the position of the locking unit 3 to ensure the connection strength between the first light-emitting body 1 and the second light-emitting body 2. In other words, when the locking unit 3 is threadedly connected to the second fixing part 251, the first main body area 14 and the second main body area 24 can be locked by the cooperation of the first limiting part 137 and the locking unit 3 to prevent the first main body area 14 and the second main body area 24 from angular deflection at the connection.

In this way, both ends of the LED straight tube lamp can be connected to the corresponding lamp holders. In some embodiments, only one of the first electrical connector 414 and the second electrical connector 434 is connected to external power to power the LED straight tube lamp.

[0117] The first connecting portion 442 may be provided with a first combining unit 452, and the second connecting portion 462 may be provided with a second combining unit 472. The first combining unit 452 is connected to the second combining unit 472 to further complete the connection between the first connecting portion 442 and the second connecting portion 462, thereby improving the stability of the connection between the two. The first combining unit 452 is provided at the end surface of the first connecting portion 442, and the second combining unit 472 is provided at the end surface of the second connecting portion 462.

[0118] The first combination unit 452 may be a buckle, which is disposed on the end surface of the first connection portion 442, and the second combination unit 472 is a corresponding buckle hole, and the buckle is buckled into the buckle hole to match. When the buckle and the buckle hole are matched, the first component 400 and the second component 420 cannot be easily or non-destructively disassembled.

[0119] Furthermore, the second connection portion 462 may be provided with a third combination unit 474 (also referred to as a fixing portion), and the first connection portion 442 may be provided with a corresponding fourth combination unit 454 (also referred to as a connection hole), and the third combination unit 474 is connected to the fourth combination unit 454 to further complete the connection between the first connection portion 442 and the second connection portion 462, thereby improving the stability of the connection between the two. The third combination unit 474 is provided at the end surface of the second connection portion 462, and the fourth combination unit 454 is provided at the end surface of the first connection portion 442.

[0120] The first combination unit 452 and the third combination unit 474 have substantially the same structure. That is, the third combination unit 474 may be a buckle, which is disposed on the end surface of the second connection portion 462, and the fourth combination unit 454 is a corresponding buckle hole, and the buckle is buckled into the buckle hole for matching.

[0121] The connection unit 440 in this embodiment may further include a locking unit 480, which is sleeved on the outside of the first connection part 442 and the second connection part 462, and the inner wall of the locking unit 480 radially limits the movable space of the first connection part 442 and the second connection part 462 to prevent the first connection part 442 and the second connection part 462 from forming a certain angle due to the assembly gap after the first connection part 442 and the second connection part 462 are matched, and finally the LED straight tube lamp is bent at the connection unit 440.

[0122] The locking unit 480 includes a limiting portion 482. When the locking unit 480 is sleeved outside the first connecting portion 442, the limiting portion 482 corresponds to the end of the first connecting portion 442 in the axial direction. A threaded portion 484 (also called a third fixing portion) is provided on the other side of the locking unit 480 relative to the limiting portion 482. The threaded portion 484 cooperates with the thread on the second connecting portion 462. When the thread is locked, the locking unit 480 locks the first connecting portion 442 and the second connecting portion 462 in the axial direction of the LED straight tube lamp to prevent the first connecting portion 442 and the second connecting portion 462 from loosening.

[0123] A stopper 476 may be provided on the second connection portion 462 to limit over-tightening of the locking unit 480. Specifically, the stopper 476 may stop the locking unit 480 in the axial direction of the LED straight tube lamp to prevent over-tightening of the locking unit 480. The outer diameter of the stopper 476 is substantially the same as the outer diameter of the locking unit 480 to maintain consistency in appearance.

[0124] In this embodiment, the total length of the LED straight tube lamp exceeds 2300 mm and does not exceed 2400 mm. When the length of the connecting unit 440 does not exceed 40 mm, 38 mm, 35 mm or 33 mm, it can ensure that the curvature (or deflection) of the LED straight tube lamp does not exceed one thousandth. In other words, when the ratio of the length of the connecting unit 440 to the total length of the LED straight tube lamp does not exceed 1.5% or 1.4%, it can ensure that the curvature (or deflection) of the LED straight tube lamp does not exceed one thousandth. Therefore, when the structural connection is completed, the effect of the setting of the connecting unit 440 on the length reduction of the light-emitting area can be guaranteed as much as possible, and the light-emitting length of the LED straight tube lamp can be guaranteed. In this embodiment, in the state after installation, or when support is provided to the two ends (the first end 412 and the second end 432) of the LED straight tube lamp, and when no support is provided to the position, the distance between any position on the axis of the first component 400 and the axis of the second component 420 does not exceed 2.4 mm.

[0125] In this embodiment, the main bending point of the LED straight tube lamp is at the connection between the first component 400 and the second component 420. Considering that the two ends of the LED straight tube are used as installation and support positions, less weight should be arranged at the main bending point of the LED straight tube lamp to prevent the connection between the first component 400 and the second component 420 from increasing the bending degree due to excessive weight setting. And relatively more weight can be configured in the first end 412 and the second end 432. Since this part of the weight is supported more directly, the influence on the bending degree will be further reduced. In this embodiment, the unit weight of the LED straight tube lamp at the first end 412 and / or the second end 432 in the length direction is greater than the unit weight at the connecting unit 440. The unit weight at the first end 412 and / or the second end 432 here refers to the ratio of the total weight at the first end 412 and / or the second end 432 (including the weight of the first end 412 and / or the second end 432 itself and the components inside it) to the length of the first end 412 and / or the second end 432. The unit weight of the connection unit 440 refers to the ratio of the total weight of the connection unit 440 (including the weight of the connection unit 440 itself and the weight of its internal components) to the length of the connection unit 440 .

Taking the embodiment in which the second electrical connecting portion 23e is a hole as an example, the second electrical connecting piece 23s is located in the hole.
