Description

Technical Field

[0001] This application relates to the field of LED lighting fixtures, and more particularly to an energy-saving LED lamp that is easy to adjust. Background Technology

[0002] LED lights, also known as light-emitting diodes, are solid-state light sources that emit light when electricity is applied to a semiconductor chip. They have advantages such as energy saving, long lifespan, and small size, and are widely used in lighting, display, and other fields. Downlights are a type of LED light, a type of lighting fixture that is embedded in the ceiling and emits light evenly downwards, making them particularly suitable for designs without a main light or for basic lighting.

[0003] Existing downlights (such as) Figure 1 As shown, the lamp includes a lamp tube 1, with a mounting hole 2 extending through one end of the lamp tube 1. A lamp body 3 is installed inside the mounting hole 2. A retaining ring 4 is installed at the opening of the mounting hole 2 on the lamp tube 1. Spring clips 5 are installed on both sides of the lamp tube 1. The lamp tube, along with the spring clips, is inserted into a preset socket. The spring clips engage with the side wall of the socket to install the downlight. When the downlight needs to be replaced later, it can be removed from the socket by pulling the lamp tube to drive the spring clips to rotate. However, driving the spring clips to rotate requires a large force, which can easily damage the socket when pulling, thus affecting the subsequent installation of the downlight. Summary of the Invention

[0004] To reduce the probability of damage to the installation area when disassembling downlights, this application provides an energy-saving LED light that is easy to adjust.

[0005] The energy-saving LED lamp that is easy to adjust provided in this application adopts the following technical solution: An easily adjustable energy-saving LED lamp includes a lamp tube with a mounting hole extending through one end. A lamp body is installed in the mounting hole. A retaining ring is installed at the opening of the mounting hole. Spring contacts are installed on both sides of the lamp tube and are rotatably mounted on the side wall of the lamp tube. A driving mechanism is installed on the lamp tube, including a driving rod and a pull rod. The driving rod is slidably mounted on the lamp tube. One end of the pull rod is hinged to the driving rod, and the other end is hinged to the spring contacts. Pulling the driving rod drives the spring contacts to rotate toward the lamp tube and retract into the side wall of the lamp tube.

[0006] By adopting the above technical solution, the drive mechanism can be set up so that when disassembly is required, the pull rod can be pulled to drive the pull rod to slide and rotate, thereby driving the spring to rotate and be stored in the lamp tube. This facilitates the disassembly of the lamp tube without having to pull the lamp tube forcefully, reducing the probability of damage to the lamp tube installation area caused by the force of the spring on the lamp tube installation area when disassembling the lamp tube.

[0007] Optionally, a locking block is hinged to the end of the drive rod away from the pull rod, and a locking groove is opened on the side wall of the lamp tube, and the locking block is locked into the locking groove by rotation.

[0008] Optionally, the blocking ring is detachably mounted on the lamp cylinder, and the blocking ring cover is arranged at the end of the driving rod away from the pull rod.

[0009] Optionally, a limiting block is fixedly arranged on the blocking ring, and the limiting block abuts against the clamping block to limit rotation of the clamping block.

[0010] Optionally, the lamp body comprises a mounting table and an LED lamp plate, the mounting table is rotatably mounted in the lamp cylinder, and the LED lamp plate is mounted on the side of the mounting table facing the opening of the lamp cylinder.

[0011] Optionally, the mounting table comprises a mounting portion and a detachable portion, the mounting portion is mounted on the lamp cylinder, the detachable portion is detachably mounted on the mounting portion, and the LED lamp plate is mounted on the detachable portion.

[0012] Optionally, a rotating assembly is arranged between the mounting table and the lamp cylinder, the rotating assembly comprises a universal ball, a positioning block, a driving block and a return spring, the universal ball is fixedly arranged on the mounting table, more than half of the universal ball is rotatably embedded in the lamp cylinder, the positioning block is slidably arranged on the universal ball, the positioning block abuts against the lamp cylinder through sliding, the driving block is slidably mounted on the mounting portion, the driving block is arranged on the side of the mounting portion facing the opening of the lamp cylinder, the return spring is arranged between the positioning block and the universal ball, the elastic force of the return spring drives the positioning block to be accommodated in the universal ball, when the detachable portion is mounted on the mounting portion, the detachable portion pushes the driving block to slide and insert into the mounting table to drive the positioning block to slide and abut against the lamp cylinder.

[0013] Optionally, an electric wire is arranged in the lamp cylinder, one end of the electric wire penetrates through the end of the lamp cylinder away from the opening of the mounting hole and extends out of the lamp cylinder, and the other end of the electric wire extends into the mounting portion from the side wall of the mounting portion and penetrates through the mounting portion toward the opening of the mounting hole.

[0014] Optionally, a embedding groove is arranged on the mounting portion, a conductive sheet is arranged at the bottom of the embedding groove, the electric wire is electrically connected with the conductive sheet, a plug block is fixedly arranged on the detachable portion, the plug block penetrates through the detachable portion, the plug block is a conductive metal block, and the plug block is matched with the embedding groove.

[0015] Optionally, a plug-in groove is arranged at the end of the lamp cylinder away from the mounting hole, a metal sheet is embedded at the bottom of the plug-in groove, the electric wire penetrates through the end of the lamp cylinder away from the mounting hole to electrically connect with the metal sheet, a connector is detachably mounted in the plug-in groove, the connector is electrically connected with the metal sheet by being inserted into one end of the plug-in groove, and the end of the connector away from the plug-in groove is connected with a power supply circuit.

[0016] In summary, the present application has at least one of the following beneficial technical effects: 1. The drive mechanism is designed so that when disassembly is required, pulling the drive rod will cause the pull rod to slide and rotate, thereby causing the spring to rotate and be stored in the lamp tube. This facilitates the disassembly of the lamp tube without having to pull the lamp tube forcefully, reducing the probability of damage to the lamp tube installation area caused by the force exerted by the spring on the lamp tube during disassembly. 2. When the card block is inserted into the card slot, it can restrict the sliding of the drive rod, thereby reducing the probability that the drive rod will be accidentally touched, causing the spring to rotate and the lamp to fall. While restricting the sliding of the drive rod, it can also support the spring. After the spring loses its elasticity, the drive rod and the pull rod can still make the spring open, thereby reducing the probability of the lamp falling. 3. The retaining ring can cover the drive rod, reducing the probability of the drive rod being accidentally touched. It can also cover the drive rod to improve the aesthetics of the downlight after installation. The detachable retaining ring can also be selected according to the needs. 4. The direction of the downlight beam can be adjusted by rotating the mounting platform on the lamp barrel. The split mounting platform facilitates the replacement of LED panels when they are damaged or need to be replaced with LED panels of different colors or brightness. By removing the disassembly part, the mounting part can be rotated to adjust the mounting platform and thus adjust the beam angle of the LED panel. After the mounting platform is adjusted, the disassembly part is installed to allow the drive block to move all the positioning blocks to slide against the lamp barrel and fix the position of the mounting platform. 5. When the plug is inserted into the slot, it connects with the conductive sheet and connects the circuit of the LED board and the wires. Even though the plug connects the LED board and the wires, it is still a connection structure where the disassembly part is fixed on the installation part. In order to improve the firmness of the plug in the slot, when the plug is inserted into the slot, the elastic protrusion is squeezed and deformed, thereby increasing the friction between the plug and the slot, reducing the probability of the plug coming out of the slot, and improving the stability of the plug insertion. When the elastic protrusion loses its elasticity due to long-term insertion and removal, the elastic card is replaced to ensure the elastic effect of the elastic card. 6. When the insert is inserted into the groove, the elastic protrusion is compressed and deformed, thereby increasing the friction between the insert and the groove, reducing the probability of the insert coming out of the groove, and improving the stability of the insert insertion. When the elastic protrusion loses its elasticity due to long-term insertion and removal, the elastic card is replaced to ensure the elastic effect of the elastic card. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 2-8 The present application will be further described with reference to specific embodiments: First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Example 1

[0027] This application discloses an easily adjustable energy-saving LED lamp, referring to... Figure 2 and Figure 3 The lamp includes a circular lamp tube 1 with a mounting hole 2 extending through one end. A lamp body 3 for lighting is installed inside the mounting hole 2. A retaining ring 4 is installed at the opening of the mounting hole 2 to cover the gap between the lamp tube 1 and the installation area after installation, improving the aesthetics of the lamp tube 1. Spring tabs 5 are installed on both sides of the lamp tube 1. The spring tabs 5 are rotatably mounted on the side wall of the lamp tube 1 and have elasticity. Normally, the spring tabs 5 extend beyond the side wall of the lamp tube 1. When one hinged end of the spring tab 5 is compressed, the spring tab 5 rotates and retracts into the side wall of the lamp tube 1. Each of the two spring tabs 5 on the lamp tube 1 has a corresponding [missing information - likely a device or device]. The drive mechanism 6 includes a drive rod 61 and a pull rod 62. The drive rod 61 is slidably mounted on the lamp tube 1. One end of the pull rod 62 is hinged to the drive rod 61, and the other end is hinged to the spring piece 5. Pulling the drive rod 61 drives the spring piece 5 to rotate toward the lamp tube 1 and be stored in the side wall of the lamp tube 1. The drive mechanism 6 allows for easy disassembly of the lamp tube 1 by pulling the drive rod 61 to drive the pull rod 62 to slide and rotate, thereby causing the spring piece 5 to rotate and be stored in the lamp tube 1. This facilitates the disassembly of the lamp tube 1 without having to pull the lamp tube 1 forcefully, reducing the probability of damage to the lamp tube 1 mounting area caused by the force exerted by the spring piece 5 on the lamp tube 1 mounting area during disassembly.

[0028] Reference Figure 3 and Figure 4A locking block 7 is hinged to the end of the drive rod 61 away from the pull rod 62. A slot 8 is provided on the side wall of the lamp tube 1. The locking block 7 is engaged in the slot 8 by rotation. When the locking block 7 is inserted into the slot 8, it can restrict the sliding of the drive rod 61, thereby reducing the probability that the drive rod 61 will be accidentally touched, causing the spring 5 to rotate and the lamp tube 1 to fall. The restricted sliding of the drive rod 61 can also support the spring 5. After the spring 5 loses its elasticity, the drive rod 61 and the pull rod 62 can still keep the spring 5 open, thereby reducing the probability of the lamp tube 1 falling. The retaining ring 4 is detachably installed on the lamp tube 1. The retaining ring 4 covers the end of the drive rod 61 away from the pull rod 62. The retaining ring 4 can cover the drive rod 61, reducing the probability of the drive rod 61 being accidentally touched, and can also cover the spring 5. The drive rod 61 enhances the aesthetics of the downlight after installation; a limiting block 9 is fixed on the retaining ring 4, which abuts against the locking block 7 to restrict the rotation of the locking block 7. The setting of the limiting block 9 can restrict the rotation of the locking block 7, thereby reducing the probability of the locking block 7 rotating out of the locking slot 8; the retaining ring 4 includes a mounting plate 41, a shielding plate 42 and a receiving plate 43. The mounting plate 41 is an annular plate with a U-shaped cross section. The mounting plate 41 is detachably installed at the opening of the mounting hole 2 of the lamp tube 1 by bolts. The shielding plate 42 is fixed on the side of the mounting plate 41 away from the lamp tube 1. The shielding plate 42 is used to block the gap between the lamp tube 1 and the installation area. The receiving plate 43 is fixed on the side of the mounting plate 41 located inside the mounting hole 2. The receiving plate 43 supports the transparent glass lamp cover 10 on the side facing the bottom of the mounting hole 2.

[0029] Reference Figure 3 and Figure 5 The lamp body 3 includes a mounting platform 31 and an LED light board 32. The mounting platform 31 is rotatably mounted inside the lamp barrel 1, and the LED light board 32 is mounted on the side of the mounting platform 31 facing the opening of the lamp barrel 1. In this embodiment, the LED light board 32 is a circuit board with LED beads installed. The direction of the downlight can be adjusted by rotating the mounting platform 31 on the lamp barrel 1. The mounting platform 31 includes a mounting part 311 and a disassembly part 312. The mounting part 311 is mounted on the lamp barrel 1, and the disassembly part 312 is detachably mounted on the mounting part 311. The LED light board 32 is mounted on the disassembly part 312. With the separate mounting platform 31, it is convenient to replace the LED light board 32 when it is damaged or needs to be replaced with an LED light board 32 of a different color or brightness.

[0030] Reference Figure 1 and Figure 4A rotating assembly 11 is provided between the mounting platform 31 and the lamp tube 1. The rotating assembly 11 includes a universal ball 111, a positioning block 112, a driving block 113, and a return spring 114. The universal ball 111 is fixed to the mounting platform 31, and more than half of the universal ball 111 is rotatably embedded in the lamp tube 1. The positioning block 112 is slidably disposed on the universal ball 111. The positioning block 112 is either slidably housed in the universal ball 111 or extends out of the universal ball 111 and abuts against the lamp tube 1. When the positioning block 112 slides against the lamp tube 1, it can limit the rotation of the universal ball 111 by increasing friction. The driving block 113 is slidably mounted on the mounting part 311. The driving block 113 is disposed on the side of the mounting part 311 facing the opening of the lamp tube 1. The return spring 114 is disposed between the positioning block 112 and the universal ball 111. During this process, the spring force of the return spring 114 drives the positioning block 112 to be housed inside the universal ball 111. In this embodiment, four positioning blocks 112 are provided, and the four positioning blocks 112 are evenly distributed around the universal ball 111. The return spring 114 is provided with four corresponding positioning blocks 112. When the disassembly part 312 is installed on the mounting part 311, the disassembly part 312 pushes the drive block 113 to slide and insert into the mounting platform 31, driving the positioning block 112 to slide and abut against the lamp tube 1. By removing the disassembly part 312, the mounting part 311 can be rotated to adjust the mounting platform 31, thereby adjusting the illumination angle of the LED light panel 32. After the mounting platform 31 is adjusted, the installation of the disassembly part 312 causes the drive block 113 to drive all the positioning blocks 112 to slide and abut against the lamp tube 1 to fix the position of the mounting platform 31.

[0031] Reference Figure 3 , Figure 4 and Figure 5A wire 12 is threaded through the lamp tube 1. One end of the wire 12 passes through the lamp tube 1 away from the opening of the mounting hole 2, and the other end extends out of the lamp tube 1 to connect to the power circuit. The other end of the wire 12 extends into the mounting part 311 from the side wall of the mounting part 311 and passes through the mounting part 311 towards the opening of the mounting hole 2. A groove 13 is provided on the mounting part 311, and a conductive sheet 14 is placed at the bottom of the groove 13. In this embodiment, the conductive sheet 14 is a copper metal sheet 19. The wire 12 is electrically connected to the conductive sheet 14. A plug 15 is fixed on the disassembly part 312. The insertion block 15 is a conductive metal block, specifically a copper block, which penetrates the disassembly part 312. The insertion block 15 is adapted to the recess 13. In this embodiment, the live wire and neutral wire of the wire 12 extend into the mounting part 311 from both sides. A portion of the wire 12 is left outside the mounting part 311 to reduce the probability of the wire 12 being broken when the mounting part 311 rotates. Two recesses 13 are provided on the mounting part 311, and conductive plates 14 are placed in each recess 13. The two conductive plates 14 are respectively connected to the live wire and neutral wire of the wire 12. For fixed connection, two plug blocks 15 are provided corresponding to the recess 13. When the LED light board 32 is installed on the disassembly part 312, the two ends of the circuit of the LED light board 32 are respectively connected to the two plug blocks 15. When the plug block 15 is inserted into the recess 13, the plug block 15 is connected to the conductive sheet 14 and connects the circuit of the LED light board 32 and the wire 12. The plug block 15 is also the connection structure of the LED light board 32 and the wire 12, which is also the connection structure of the disassembly part 312 being fixed on the mounting part 311. In order to improve the firmness of the plug block 15 in the recess 13, The insert 15 has elastic cards 16 installed on both sides. The elastic cards 16 are sheet-shaped metal inserted into the insert 15. The elastic cards 16 are bent into several elastic protrusions 17. When the insert 15 is inserted into the groove 13, the elastic protrusions 17 are squeezed and deformed, thereby increasing the friction between the insert 15 and the groove 13, reducing the probability of the insert 15 dislodging from the groove 13, and improving the stability of the insert 15. When the elastic protrusions 17 are deformed and lose their elasticity due to long-term insertion and removal, the elastic cards 16 are replaced to ensure the elastic effect of the elastic cards 16.

[0032] Reference Figure 3 , Figure 4 and Figure 5The lamp holder 1 has a mounting hole 2 on one side and a plug groove 18 on the other side. A metal sheet 19 is embedded in the bottom of the plug groove 18. The metal sheet 19 is made of conductive metal. In this embodiment, the metal sheet 19 is a copper sheet. The wire 12 passes through the lamp holder 1 and is electrically connected to the metal sheet 19 at the end away from the mounting hole 2. In this embodiment, there are two metal sheets 19, which are respectively connected and fixed to the live wire and the neutral wire of the wire 12. A connector 20 is detachably installed in the plug groove 18. The connector 20 is inserted into the plug groove 18 and connects to the metal sheet 19 at one end. The connector 19 is electrically connected, and the end of the plug facing away from the socket 18 is connected to the power circuit. In this embodiment, after the connector 20 is inserted into the socket 18, the connector 20 is flush with the lamp 1. A connecting wire 21 is provided inside the connector 20. The live wire and neutral wire of the connecting wire 21 are respectively connected to the two metal pieces 19. The connecting wire 21 is connected to the power circuit, which powers the downlight to open or close the circuit. The detachable design of the socket 18 and the connector 20 allows for convenient selection of a suitable connector 20 for connection to the power circuit according to actual needs.

[0033] The implementation principle of this application embodiment is as follows: The connector 20 is inserted into the insertion slot 18. Simultaneously, after adjusting the rotation of the mounting part 311, the disassembly part 312, on which a suitable LED light board 32 is mounted, is installed on the mounting part 311. The insertion block 15 on the disassembly part 312 is inserted into the recess 13, connecting the circuit of the LED light board 32 and the wire 12. Then, the connecting wire 21 on the connector 20 is connected to the power circuit. The lamp holder 1 is then inserted into the reserved socket. During installation, the spring piece 5 is pressed and embedded in the side wall of the lamp holder 1. After the lamp holder 1 is inserted into the socket, the spring piece 5 springs back and engages with the socket. Then, the locking block 7 on the drive rod 61 is rotated to insert the locking block 7 into the locking slot 8, and the retaining ring 4 and glass lampshade 10 are installed on the lamp holder 1, completing the installation of the downlight. The lamp is then switched on via the power circuit. The LED light panel 32 is controlled to open and close. When the downlight needs to be replaced, the retaining ring 4 and the glass lamp cover 10 are removed, the locking block 7 is rotated to disengage from the slot 8, and then the drive rod 61 is pulled to drive the spring piece 5 to rotate and be stored in the side wall of the lamp tube 1. The lamp tube 1 is then removed from the socket and replaced. If the connector 20 is not damaged when replacing the lamp tube 1, the lamp tube 1 can be replaced by separating the connector 20 and the lamp tube 1 without having to reconnect the connector 20 and the power circuit. When the illumination angle of the downlight needs to be adjusted, the retaining ring 4 and the glass lamp cover 10 are removed, and then the disassembly part 312 is removed from the mounting part 311. The mounting part 311 is driven to rotate to the required adjustment angle, and then the mounting part is installed on the mounting part 311. The retaining ring 4 and the glass lamp cover 10 are then reinstalled. Example 2

[0034] Compared with Embodiment 1, the connector 20 and retaining ring 4 in this embodiment are different.

[0035] Reference Figure 6 ,Figure 7 and Figure 8 The retaining ring 4 includes a mounting plate 41 and a receiving plate 43. The mounting plate 41 is an annular plate with a U-shaped cross-section. The mounting plate 41 is detachably installed on the opening of the mounting hole 2 in the lamp tube 1 by bolts. The receiving plate 43 is fixed on the mounting plate 41 and a transparent glass lamp cover 10 is mounted on the receiving plate 43. The glass lamp cover 10 includes an integrally formed spherical part and a placement part. The spherical part is hemispherical in shape, and the placement part is fixed on the edge of the spherical part. The placement part is placed on the side of the receiving plate 43 facing the downlight. The connector 20 includes a plug block 201 and a threaded connecting post 202. The plug block 201 is inserted into the plug groove 18 and is flush with the lamp tube 1. The threaded connecting post 202 is fixed on the side of the plug block 201 away from the lamp tube 1. The threaded connecting post 202 has a connecting thread. The connector 20 has a metal wire embedded in it. There are two metal wires. One end of the two metal wires is connected to the two metal blocks respectively. The other end of one of the two metal wires extends to the threaded connecting post 202 away from the plug block 201. The other end of the other metal wire extends to the side wall of the threaded connecting post 202. By replacing the retaining ring 4 and the connector 20, the downlight can be converted into an LED energy-saving lamp. The power circuit is connected to the lamp holder of the energy-saving lamp through the threaded connecting post 202, so that it can be used as an energy-saving lamp.

[0036] The implementation principle of this application embodiment is as follows: the connector 20 is inserted into the insertion slot 18, and after adjusting the rotation of the mounting part 311, the disassembly part 312 with the appropriate LED light board 32 is installed on the mounting part 311, so that the insertion block 15 on the disassembly part 312 is inserted into the recess 13 to connect the circuit of the LED light board 32 and the wire 12. The locking block 7 is rotated and locked into the locking slot 8, and the retaining ring 4 and the glass lamp cover 10 are installed on the lamp tube 1. Then, the threaded connecting post 202 on the connector 20 is threaded to the lamp holder connected to the circuit power supply, so that the downlight is used as an energy-saving lamp. The opening and closing of the LED light board 32 is controlled by the switch on the power circuit. Subsequently, the stability of the lamp installation can be improved by tying a rope between the spring piece 5 and the lamp holder.
