Description

Technical Field

[0001] The present invention relates to the field of LED lighting, and specifically to an LED light-emitting module. Background Art

[0002] An LED, i.e., a light-emitting diode, is a semiconductor device that can convert electrical energy into light energy; it has the characteristics of high efficiency and low energy consumption, high light quality, basically no radiation, high plasticity of the lamp group, and diverse shapes; the core part of the LED is a wafer composed of a P-type semiconductor and an N-type semiconductor, with a conductive layer on one side of the wafer and a bracket attached to the other side; when current acts on this wafer through a wire, electrons and holes will be pushed into the quantum well, recombine within the quantum well, and then release energy in the form of photons, which is the principle of LED light emission.

[0003] During the installation of an LED, the installation of the lamp beads is crucial. The LED lamp beads can be installed horizontally, vertically, or obliquely; different installation methods will produce different lighting effects, including brightness, lamp shape, and illuminance, etc.

[0004] Existing LED lamp beads are usually installed on a circuit board by means of soldering paste. In use and observation, it is found that because the installation position will deviate, after the lamp beads are installed on the base of the circuit board, the positions of the lamp beads still need to be finely adjusted, which will make the installation steps of the lamp beads more cumbersome and also reduce the accuracy of the installation position of the lamp beads.

[0005] Therefore, an LED light-emitting module is proposed to solve the above problems. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: An LED lighting module of the present invention includes a lamp housing; a lamp cover is installed on the surface of the lamp housing; a plurality of clamping blocks are fixedly connected to the inner side wall of the lamp housing; the clamping blocks are L-shaped structures; a circuit board is installed inside the lamp housing; a plurality of lamp beads are installed on the surface of the circuit board; a protective shell is fixedly connected to the middle of the lamp bead; a plurality of positioning rings are fixedly connected to the surface of the circuit board; the positioning rings and the protective shell are arranged correspondingly; a plurality of sliding rods are slidably connected to the middle of the positioning ring; the sliding rods and the positioning rings are arranged in a penetrating manner; a positioning block is fixedly connected to the end of the sliding rod; the surface of the positioning block is inclined; the positioning block is located between the positioning ring and the protective shell; a tension spring is fixedly connected to the other end of the sliding rod; the tension spring and the positioning ring are fixedly connected; solder paste is applied to the installation position corresponding to the lamp bead on the surface of the circuit board. Subsequently, the staff can align the protective shell with the positioning ring and then install it. The protective shell will bring the lamp bead closer to the circuit board together. When the protective shell moves, it will enter the inside of the positioning ring and come into contact with the positioning block. Because the surface of the positioning block is inclined, the protective shell will slide along the surface of the positioning block and continue to move closer to the circuit board. The positioning block will drive the sliding rod to slide along the positioning ring under the extrusion of the protective shell, and the tension spring will also be in a stretched state. If there is a deviation in the installation position of the circuit board and the clamping block surface, the stretching lengths of the tension springs will be different. At this time, the staff can slowly move the protective shell, so that the installation positions of the protective shell and the lamp bead will be corrected under the extrusion of the positioning block, so that the lamp bead will be accurately installed on the surface of the circuit board. Repeat the above steps until all the lamp beads are installed on the surface of the circuit board. Subsequently, the circuit board can be clamped into the inside of the lamp housing through the clamping block, and then the lamp housing can be closed through the lamp cover. Finally, the circuit board is externally connected to a power supply to make the protective shell emit light, and the light will illuminate the outside through the lamp cover; the positioning block will extrude the protective shell under the elastic force of the tension spring, realizing the guidance and deviation correction of the moving path of the protective shell and the lamp bead during installation, and improving the accuracy of the installation position of the lamp bead.

[0008] Preferably, a plurality of elastic sheets are fixedly connected to the surface of the positioning ring; each group of the elastic sheets and the positioning ring are correspondingly arranged; the positioning ring is located between the protective shell and the elastic sheets; a plurality of stay cords are fixedly connected between adjacent elastic sheets; when the protective shell comes into contact with the positioning block, the positioning block will drive the sliding rod to slide along the positioning ring. At this time, the sliding rod will approach the elastic sheet and come into contact with the elastic sheet. The elastic sheet will deform under the extrusion of the sliding rod. Subsequently, the elastic sheet will exert an elastic force on the sliding rod. At this time, the positioning block will be subjected to the elastic force jointly exerted by the elastic sheet and the elastic force spring, so that the positioning block in the offset direction of the protective shell will exert a stronger extrusion force on the protective shell. At the same time, the stay cords will tie the elastic sheets into a whole, improving the stability of the overall structure of the elastic sheet; by setting the elastic sheet, the elastic sheet will exert an elastic force on the sliding rod and the positioning block, increasing the extrusion force of the positioning block on the protective shell, enhancing the deviation correction effect of the device on the protective shell and the lamp bead, improving the accuracy of lamp bead installation. At the same time, the stay cords will connect the elastic sheets into an integral structure, reducing the extrusion force on the elastic sheet when the sliding rod moves too large, reducing the damage of the elastic sheet caused by excessive deformation, and prolonging the service life of the elastic sheet.

[0009] Preferably, a plurality of reflective sheets are fixedly connected to the surface of the elastic sheet; the reflective sheet is a multi-faceted structure; when the lamp bead emits bright light, the light will spread around. These lights will come into contact with the reflective sheet. Because the surface of the reflective sheet is a multi-faceted structure, the light will be refracted when passing through the reflective sheet, increasing the distribution range of the light emitted by the lamp bead, optimizing the diffusion direction of the light emitted by the device, and enhancing the lighting effect of the device.

[0010] Preferably, a fluorescent ring is fixedly connected to the middle of the sliding rod; the fluorescent ring is a flexible structure; in the normal state, the fluorescent ring will be located inside the positioning ring. When the lamp bead is installed, the protective shell will squeeze the positioning block and the sliding rod. The sliding rod will drive the fluorescent ring to slide along the positioning ring together. When the lamp bead is accurately installed on the surface of the circuit board, all the fluorescent rings will just slide out of the positioning ring and closely adhere to the outer wall of the positioning ring. The staff can quickly judge whether the installation position of the lamp bead is accurate by observing the position of the fluorescent ring, simplifying the detection or debugging required for the device to determine the installation position of the lamp bead and shortening the working time required for checking the position of the lamp bead.

[0011] Preferably, a top plate is fixedly connected to the bottom of the positioning block; the surface of the top plate is inclined; the top plate and the surface of the positioning block are correspondingly arranged; when the protective shell is installed with the lamp beads, the protective shell will contact the positioning block and the top plate successively, and when the lamp beads are installed on the surface of the card block, the protective shell will contact the inclined surface of the top plate. When the lamp beads need to be removed, the staff can press the elastic sheet so that the elastic sheet squeezes the slide rod and the positioning block. At this time, the top plate will also squeeze the protective shell so that the protective shell will separate from the circuit board with the lamp beads, and the protective shell will slide along the surface of the top plate until it reaches the bottom of the positioning block, and then the protective shell will continue to slide along the surface of the positioning block until the protective shell is separated from the positioning block. At this time, the protective shell and the lamp beads are in an active state, so that the device can quickly disassemble the protective shell and the lamp beads.

[0012] Preferably, a plurality of first fixed grooves are provided in the middle of the block; a plurality of spring telescopic rods are fixedly connected to the inner side walls of the first fixed grooves; the ends of adjacent spring telescopic rods are fixedly connected to a limit plate; the limit plate and the first fixed groove are slidably connected; the limit plate is an arc-shaped structure; when the circuit board is inserted into the interior of the lamp housing along the block, the circuit board will slide along the surface of the block, and the circuit board will come into contact with the limit plate during the movement. After being squeezed, the limit plate will slide along the first fixed groove and put the spring telescopic rod into a compressed state, and then the spring telescopic rod will exert elastic force on the limit plate to make the limit plate approach the circuit board. Because the limit plate is an arc-shaped structure, the circuit board will be close to the inner wall of the lamp housing after passing through the limit plate, and the limit plate will limit the top of the circuit board, so that the circuit board will be squeezed by the block and the limit plate at the same time, thereby improving the stability of the circuit board during operation.

[0013] Preferably, a second fixing groove is provided in the middle of the limiting plate; a pressure block is rotatably connected to the middle of the second fixing groove; a groove is provided on the surface of the pressure block; the groove is a conical structure; when the circuit board comes into contact with the limiting plate, it will also come into contact with the pressure block, and the pressure block will rotate under the extrusion of the circuit board and make the groove face the surface of the circuit board. At this time, the circuit board will come into contact with the inner wall of the groove and the groove will be in an inclined state. Due to the effect of gravity, the circuit board will be squeezed by the pressure block, further improving the stability of the circuit board during installation.

[0014] Preferably, a plurality of buffer pads are fixedly connected to the surface of the groove; the surface of the buffer pad is an arc-shaped structure; when the groove contacts the circuit board, the buffer pad will also contact the circuit board. Because the buffer pad is made of flexible material, when the buffer pad contacts the circuit board, the damage to the circuit board caused by excessive squeezing of the pressure block will be reduced, thereby protecting the circuit board.

[0015] Preferably, the surface of the positioning block is in an arc transition; the positioning blocks and the sliding rods are both arranged in a circumferential array; since the surface of the positioning block is in an arc transition, the resistance between the positioning block and the protective case will be reduced when they come into contact, reducing the wear caused by friction between the positioning block and the protective case. At the same time, since the positioning blocks and the sliding rods are both arranged in a circumferential array, they can better center and correct the position of the protective case and the lamp beads.

[0016] Preferably, the surface of the clamping block is in an arc structure; the clamping block is in an L-shaped structure; since the clamping block is in an L-shaped structure and its surface is in an arc structure, the clamping block will stably limit and clamp the circuit board, and at the same time, it also reduces the scratches caused by friction when the circuit board is installed along the clamping block.

[0017] The advantages of the present invention are as follows:

[0018] 1. For the LED light-emitting module described in the present invention, the positioning block will extrude the protective case under the elastic force of the elastic spring, realizing the guidance and correction of the moving path during the installation of the protective case and the lamp beads, and improving the accuracy of the installation position of the lamp beads.

[0019] 2. For the LED light-emitting module described in the present invention, by setting the elastic sheet, the elastic sheet will apply an elastic force to the sliding rod and the positioning block, increasing the extrusion effect of the positioning block on the protective case, enhancing the correction effect of the device on the protective case and the lamp beads, improving the accuracy of the installation of the lamp beads. At the same time, the pull rope will connect the elastic sheets into an integral structure, reducing the extrusion effect on the elastic sheet when the sliding rod moves too much, reducing the damage to the elastic sheet caused by excessive deformation, and prolonging the service life of the elastic sheet.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] The following gives specific embodiments.

[0032] Please refer to Figures 1 to 8As shown in the figure, an LED lighting module according to an embodiment of the present invention includes a lamp housing 1; a lamp cover 12 is installed on the surface of the lamp housing 1; a plurality of clamping blocks 13 are fixedly connected to the inner side wall of the lamp housing 1; the clamping blocks 13 are L-shaped structures; a circuit board 14 is installed inside the lamp housing 1; a plurality of lamp beads 110 are installed on the surface of the circuit board 14; a protective shell 15 is fixedly connected to the middle of the lamp bead 110; a plurality of positioning rings 16 are fixedly connected to the surface of the circuit board 14; the positioning rings 16 and the protective shell 15 are arranged correspondingly; a plurality of sliding rods 18 are slidably connected to the middle of the positioning ring 16; the sliding rods 18 and the positioning ring 16 are arranged in a penetrating manner; a positioning block 17 is fixedly connected to the end of the sliding rod 18; the surface of the positioning block 17 is inclined; the positioning block 17 is located between the positioning ring 16 and the protective shell 15; the other end of the sliding rod 18 is fixedly connected to an elastic spring 19; the elastic spring 19 and the positioning ring 16 are fixedly connected to each other; during operation, solder paste can be applied to the installation position corresponding to the lamp bead 110 on the surface of the circuit board 14. Subsequently, the staff can align the protective shell 15 with the positioning ring 16 and then install it. The protective shell 15 will bring the lamp bead 110 closer to the circuit board 14 together. When the protective shell 15 moves, it will enter the inside of the positioning ring 16 and come into contact with the positioning block 17. Because the surface of the positioning block 17 is inclined, the protective shell 15 will slide along the surface of the positioning block 17 and continue to move closer to the circuit board 14. The positioning block 17 will drive the sliding rod 18 to slide along the positioning ring 16 under the extrusion of the protective shell 15, and the elastic spring 19 will also be in a stretched state. If there is a deviation in the installation positions of the circuit board 14 and the clamping block 13, the stretching lengths of the elastic springs 19 will be different. At this time, the staff can slowly move the protective shell 15, so that the installation positions of the protective shell 15 and the lamp bead 110 will be corrected under the extrusion of the positioning block 17, so that the lamp bead 110 will be accurately installed on the surface of the circuit board 14. Repeat the above steps until all the lamp beads 110 are installed on the surface of the circuit board 14. Subsequently, the circuit board 14 can be clamped into the inside of the lamp housing 1 through the clamping block 13, and then the lamp housing 1 can be closed through the lamp cover 12. Finally, an external power supply is connected to the circuit board 14 to make the protective shell 15 emit light, and the light will illuminate the outside through the lamp cover 12; the positioning block 17 will extrude the protective shell 15 under the elastic force of the elastic spring 19, realizing the guidance and deviation correction of the moving path of the protective shell 15 and the lamp bead 110 during installation, and improving the accuracy of the installation position of the lamp bead 110.

[0033] Please refer to Figure 2 and Figure 4As shown, multiple groups of elastic pieces 2 are fixedly connected to the surface of the positioning ring 16; each group of the elastic pieces 2 and the positioning ring 16 are correspondingly arranged; the positioning ring 16 is located between the protective shell 15 and the elastic pieces 2; a plurality of stay cords 22 are fixedly connected between adjacent elastic pieces 2; when the protective shell 15 comes into contact with the positioning block 17, the positioning block 17 will drive the sliding rod 18 to slide along the positioning ring 16. At this time, the sliding rod 18 will approach the elastic piece 2 and come into contact with the elastic piece 2. The elastic piece 2 will deform under the extrusion of the sliding rod 18. Subsequently, the elastic piece 2 will exert an elastic force on the sliding rod 18. At this time, the positioning block 17 will be subjected to the elastic forces jointly exerted by the elastic piece 2 and the elastic force spring 19, so that the positioning block 17 that offsets the direction of the protective shell 15 will exert a stronger extrusion force on the protective shell 15. At the same time, the stay cords 22 will tie the elastic pieces 2 into a whole, improving the stability of the overall structure of the elastic pieces 2; by providing the elastic pieces 2, the elastic pieces 2 will exert an elastic force on the sliding rod 18 and the positioning block 17, increasing the extrusion force of the positioning block 17 on the protective shell 15, enhancing the deviation correction effect of the device on the protective shell 15 and the lamp bead 110, improving the installation accuracy of the lamp bead 110. At the same time, the stay cords 22 will connect the elastic pieces 2 into an overall structure, reducing the extrusion force on the elastic pieces 2 when the sliding rod 18 moves too much, reducing the damage to the elastic pieces 2 caused by excessive deformation, and extending the service life of the elastic pieces 2.

[0034] Please refer to Figure 3 and Figure 4 As shown, a plurality of reflecting pieces 3 are fixedly connected to the surface of the elastic piece 2; the reflecting pieces 3 are multi-faceted structures; when the lamp bead 110 emits light, the light will spread around. These lights will come into contact with the reflecting pieces 3. Because the surface of the reflecting pieces 3 is a multi-faceted structure, the light will be refracted when passing through the reflecting pieces 3, increasing the distribution range of the light emitted by the lamp bead 110, optimizing the diffusion direction of the light emitted by the device, and enhancing the lighting effect of the device.

[0035] Please refer to Figure 5 As shown, a fluorescent ring 4 is fixedly connected to the middle of the sliding rod 18; the fluorescent ring 4 is a flexible structure; in the normal state, the fluorescent ring 4 will be located inside the positioning ring 16. When the lamp bead 110 is installed, the protective shell 15 will squeeze the positioning block 17 and the sliding rod 18. The sliding rod 18 will drive the fluorescent ring 4 to slide along the positioning ring 16 together. When the lamp bead 110 is accurately installed on the surface of the circuit board 14, all the fluorescent rings 4 will just slide out of the positioning ring 16 and closely adhere to the outer wall of the positioning ring 16. The staff can quickly judge whether the installation position of the lamp bead 110 is accurate by observing the position of the fluorescent ring 4, simplifying the detection or debugging required for the device to determine the installation position of the lamp bead 110 and shortening the working time required for checking the position of the lamp bead 110.

[0036] Please refer to Figure 5As shown, a top plate 5 is fixedly connected to the bottom of the positioning block 17; the surface of the top plate 5 is inclined; the surface of the top plate 5 and the positioning block 17 are correspondingly arranged; when the protective case 15 with the lamp bead 110 is installed, the protective case 15 will come into contact with the positioning block 17 and the top plate 5 successively. When the lamp bead 110 is installed on the surface of the clamping block 13, the protective case 15 will come into contact with the inclined surface of the top plate 5. When it is necessary to disassemble the lamp bead 110, the staff can press the elastic piece 2 so that the elastic piece 2 squeezes the sliding rod 18 and the positioning block 17. At this time, the top plate 5 will also squeeze the protective case 15 so that the protective case 15 will drive the lamp bead 110 to separate from the circuit board 14. The protective case 15 will slide along the surface of the top plate 5 until it reaches the bottom of the positioning block 17, and then the protective case 15 will continue to slide along the surface of the positioning block 17 until the protective case 15 detaches from the positioning block 17. At this time, the protective case 15 and the lamp bead 110 are in a movable state, realizing the quick disassembly of the protective case 15 and the lamp bead 110 by the device.

[0037] Please refer to Figures 6 to 8 As shown, a plurality of first fixing grooves 6 are formed in the middle of the clamping block 13; a plurality of spring telescopic rods 62 are fixedly connected to the inner side wall of the first fixing groove 6; the ends of adjacent spring telescopic rods 62 are fixedly connected with a limiting plate 63; the limiting plate 63 is slidably connected with the first fixing groove 6; the limiting plate 63 is of an arc-shaped structure; when the circuit board 14 is clamped into the lamp housing 1 along the clamping block 13, the circuit board 14 will slide along the surface of the clamping block 13. During the movement, the circuit board 14 will come into contact with the limiting plate 63. After being squeezed, the limiting plate 63 will slide along the first fixing groove 6 and the spring telescopic rod 62 will be in a compressed state. Subsequently, the spring telescopic rod 62 will exert an elastic force on the limiting plate 63 to make the limiting plate 63 approach the circuit board 14. Because the limiting plate 63 is of an arc-shaped structure, after the circuit board 14 passes through the limiting plate 63, it will closely adhere to the inner wall of the lamp housing 1. The limiting plate 63 will limit the top of the circuit board 14, so that the circuit board 14 will be squeezed by both the clamping block 13 and the limiting plate 63, improving the stability of the circuit board 14 during operation.

[0038] Please refer to Figure 8 As shown, a second fixing groove 7 is formed in the middle of the limiting plate 63; a pressing block 72 is rotatably connected to the middle of the second fixing groove 7; a groove 73 is formed on the surface of the pressing block 72; the groove 73 is of a conical structure; when the circuit board 14 comes into contact with the limiting plate 63, it will also come into contact with the pressing block 72. The pressing block 72 will rotate under the extrusion of the circuit board 14 and make the groove 73 face the surface of the circuit board 14. At this time, the circuit board 14 will come into contact with the inner wall of the groove 73 and the groove 73 is in an inclined state. Due to the gravity, the circuit board 14 will be squeezed by the pressing block 72, further improving the stability of the circuit board 14 during installation.

[0039] Please refer to Figure 8As shown, a plurality of buffer pads 8 are fixedly connected to the surface of the groove 73; the surface of the buffer pad 8 is an arc structure; when the groove 73 comes into contact with the circuit board 14, the buffer pad 8 will also come into contact with the circuit board 14. Since the buffer pad 8 is made of a flexible material, the damage caused by the excessive extrusion of the pressing block 72 on the circuit board 14 can be reduced when the buffer pad 8 comes into contact with the circuit board 14, playing a protective role for the circuit board 14.

[0040] Please refer to Figure 5 As shown, the surface of the positioning block 17 is arc-shaped transition; the positioning block 17 and the sliding rod 18 are both arranged in a circumferential array; because the surface of the positioning block 17 is arc-shaped transition, the resistance between the positioning block 17 and the protective case 15 can be reduced when the positioning block 17 comes into contact with the protective case 15, and the wear caused by friction between the positioning block 17 and the protective case 15 can be reduced. At the same time, because the positioning block 17 and the sliding rod 18 are both arranged in a circumferential array, it can better center and correct the position of the protective case 15 and the lamp bead 110.

[0041] Please refer to Figure 7 As shown, the surface of the clamping block 13 is an arc structure; the clamping block 13 is an L-shaped structure; because the clamping block 13 is an L-shaped structure and the surface is an arc structure, the clamping block 13 can stably limit and clamp the circuit board 14, and at the same time, the scratch caused by friction when the circuit board 14 is installed along the clamping block 13 can also be reduced.

[0042] Working principle: Apply solder paste at the installation position corresponding to the lamp beads 110 on the surface of the circuit board 14. Subsequently, the staff can align the protective case 15 with the positioning ring 16 and then install it. The protective case 15 will bring the lamp beads 110 closer to the circuit board 14 together. When the protective case 15 moves, it will enter the inside of the positioning ring 16 and come into contact with the positioning block 17. Since the surface of the positioning block 17 is inclined, the protective case 15 will slide along the surface of the positioning block 17 and continue to approach the circuit board 14. The positioning block 17 will drive the sliding rod 18 to slide along the positioning ring 16 under the extrusion of the protective case 15, and the elastic spring 19 will also be in a stretched state. If there is a deviation in the installation positions of the circuit board 14 and the surface of the clamping block 13, the stretching lengths between the elastic springs 19 will be different. At this time, the staff can slowly move the protective case 15 so that the installation positions of the protective case 15 and the lamp beads 110 will be corrected under the extrusion of the positioning block 17, so that the lamp beads 110 will be accurately installed on the surface of the circuit board 14. Repeat the above steps until all the lamp beads 110 are installed on the surface of the circuit board 14. Subsequently, the circuit board 14 can be clamped into the interior of the lamp housing 1 through the clamping block 13, and then the lamp housing 1 can be closed by the lamp shade 12. Finally, connecting an external power supply to the circuit board 14 can make the protective case 15 emit bright light, and the bright light will illuminate the outside through the lamp shade 12; when the protective case 15 comes into contact with the positioning block 17, it will cause the positioning block 17 to drive the sliding rod 18 to slide along the positioning ring 16. At this time, the sliding rod 18 will approach the elastic sheet 2 and come into contact with the elastic sheet 2. The elastic sheet 2 will deform under the extrusion of the sliding rod 18, and then the elastic sheet 2 will exert an elastic force on the sliding rod 18. At this time, the positioning block 17 will be subjected to the elastic forces jointly exerted by the elastic sheet 2 and the elastic spring 19, so that the positioning block 17 that deflects the direction of the protective case 15 will exert a stronger extrusion force on the protective case 15. At the same time, the pull rope 22 will tie the elastic sheets 2 into a whole, improving the stability of the overall structure of the elastic sheet 2; by setting the elastic sheet 2, the elastic sheet 2 will exert an elastic force on the sliding rod 18 and the positioning block 17, increasing the extrusion force of the positioning block 17 on the protective case 15, enhancing the deviation correction effect of the device on the protective case 15 and the lamp beads 110, improving the installation accuracy of the lamp beads 110. At the same time, the pull rope 22 will connect the elastic sheets 2 into an overall structure, reducing the extrusion effect on the elastic sheet 2 when the sliding rod 18 moves too much, and reducing the damage to the elastic sheet 2 caused by excessive deformation; when the lamp beads 110 emit bright light, the light will spread around. These lights will come into contact with the reflective sheet 3. Since the surface of the reflective sheet 3 is a multi-faceted structure, the light will be refracted when passing through the reflective sheet 3, increasing the distribution range of the light emitted by the lamp beads 110 and optimizing the diffusion direction of the light emitted by the device;In the normal state, the fluorescent ring 4 is located inside the positioning ring 16. When the lamp bead 110 is installed, the protective shell 15 will squeeze the positioning block 17 and the sliding rod 18. The sliding rod 18 will drive the fluorescent ring 4 to slide along the positioning ring 16 together. When the lamp bead 110 is accurately installed on the surface of the circuit board 14, all the fluorescent rings 4 will just slide out of the positioning ring 16 and closely adhere to the outer wall of the positioning ring 16. The staff can quickly judge whether the installation position of the lamp bead 110 is accurate by observing the position of the fluorescent ring 4, simplifying the detection or debugging required for the device to determine the installation position of the lamp bead 110; when the protective shell 15 installs the lamp bead 110, the protective shell 15 will come into contact with the positioning block 17 and the top plate 5 successively. When the lamp bead 110 is installed on the surface of the clamping block 13, the protective shell 15 will come into contact with the inclined surface of the top plate 5. When the lamp bead 110 needs to be disassembled, the staff can press the elastic piece 2 so that the elastic piece 2 squeezes the sliding rod 18 and the positioning block 17. At this time, the top plate 5 will also squeeze the protective shell 15 so that the protective shell 15 will drive the lamp bead 110 to separate from the circuit board 14. The protective shell 15 will slide along the surface of the top plate 5 until it reaches the bottom of the positioning block 17. Subsequently, the protective shell 15 will continue to slide along the surface of the positioning block 17 until the protective shell 15 separates from the positioning block 17. At this time, the protective shell 15 and the lamp bead 110 are in a movable state; when the circuit board 14 is snapped into the lamp housing 1 along the clamping block 13, the circuit board 14 will slide along the surface of the clamping block 13. During the movement, the circuit board 14 will come into contact with the limiting plate 63. After being squeezed, the limiting plate 63 will slide along the first fixing groove 6 and compress the spring telescopic rod 62. Subsequently, the spring telescopic rod 62 will apply an elastic force to the limiting plate 63 to make the limiting plate 63 approach the circuit board 14. Since the limiting plate 63 is of an arc-shaped structure, after the circuit board 14 passes through the limiting plate 63, it will closely adhere to the inner wall of the lamp housing 1. The limiting plate 63 will limit the top of the circuit board 14, so that the circuit board 14 will be squeezed by both the clamping block 13 and the limiting plate 63; when the circuit board 14 comes into contact with the limiting plate 63, it will also come into contact with the pressing block 72. The pressing block 72 will rotate under the extrusion of the circuit board 14 and make the groove 73 face the surface of the circuit board 14. At this time, the circuit board 14 will come into contact with the inner wall of the groove 73 and the groove 73 is in an inclined state. Due to the gravity, the circuit board 14 will be squeezed by the pressing block 72; when the groove 73 comes into contact with the circuit board 14, the buffer pad 8 will also come into contact with the circuit board 14. Since the buffer pad 8 is made of a flexible material, when the buffer pad 8 comes into contact with the circuit board 14, it will reduce the damage caused by the excessive extrusion of the pressing block 72 to the circuit board 14; since the surface of the positioning block 17 is in an arc-shaped transition, when the positioning block 17 comes into contact with the protective shell 15, the resistance between the positioning block 17 and the protective shell 15 will be reduced, reducing the wear caused by friction between the positioning block 17 and the protective shell 15. At the same time, since both the positioning block 17 and the sliding rod 18 are arranged in a circumferential array;Since the clamping block 13 has an L-shaped structure and an arc-shaped surface, the clamping block 13 can stably limit and clamp the circuit board 14, and at the same time, it also reduces the scratches caused by friction when the circuit board 14 is installed along the clamping block 13.
