Description

Technical Field

[0001] This invention relates to the field of lighting devices, specifically an LED lighting device. Background Technology

[0002] LED, short for Light Emitting Diode, is a semiconductor solid-state light-emitting device. It features low energy consumption, small size, no pollution, fast response, and low driving voltage, and is mainly used in automotive lighting, street lighting, and workshop lighting. The light-emitting principle of LED chips is based on the properties of semiconductor materials. When current passes through an LED chip, electrons and holes recombine at the PN junction, releasing energy as photons, thus achieving light emission. Specifically, the core of an LED chip is a PN junction composed of P-type and N-type semiconductors. In the P-type semiconductor, holes are the majority carriers, while in the N-type semiconductor, electrons are the majority carriers. When these two semiconductor materials are combined, a potential barrier is formed between them, preventing the free flow of electrons and holes.

[0003] After prolonged use, LED lights may experience performance degradation or malfunction due to aging, driver performance decline, or poor circuit contact. In such cases, the LEDs need to be inspected or replaced.

[0004] When repairing or replacing LED chips in existing LED light fixtures, the damaged chips are usually removed and the normal chips are installed on the base using solder paste. However, during use and observation, it has been found that the solder paste takes a long time to solidify, during which time the chips are unstable and difficult to fix stably on the base surface.

[0005] Therefore, an LED lighting device is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: An LED lighting device of the present invention includes a lamp body; a base is provided inside the lamp body; a connecting component is provided on the surface of the base; the lamp body and the base are connected by the connecting component; multiple top plates are fixedly connected to the surface of the base; multiple sets of elastic sheets are fixedly connected to the surface of the top plates; adjacent elastic sheets have an arc-shaped structure and are symmetrically arranged; multiple elastic wires are fixedly connected between adjacent elastic sheets; an LED bead is provided in the middle of the base; an auxiliary plate is fixedly connected to the middle of the LED bead; the auxiliary plate is insulated; connecting plates are symmetrically fixed to the middle of the auxiliary plate; the ends of the connecting plates and the elastic sheets are correspondingly arranged; during maintenance, after removing the damaged LED bead from the surface of the base, a normal LED bead needs to be installed on the surface of the base. After the worker applies solder paste to the surface of the base, the LED bead can be installed on the surface of the base by moving the auxiliary plate. When the auxiliary board moves, the connecting plate also moves accordingly. Before the LED beads are installed, the connecting plate will contact the elastic sheet and squeeze between the elastic sheet. The elastic sheet will deform under the pressure and apply elastic force to the surface of the connecting plate. At the same time, the elastic wire will also provide tension to the elastic sheet, reducing the deformation range of the elastic sheet. When the LED beads are installed on the base surface, the connecting plate will be in full contact with the elastic sheet. At this time, the LED beads and the auxiliary board will be fixed by the friction between the connecting plate and the elastic sheet, which facilitates the bonding of solder paste between the LED beads and the base. Repeat the above operation until all LED beads are installed. Finally, after fixing the base inside the lamp body through the connecting assembly, the lamp body is connected to the power supply, and the LED beads will emit light and provide external illumination. When the LED beads are installed on the base surface, they will be fixed by the elastic force of the elastic sheet and elastic wire on the connecting plate, reducing the shaking caused by the LED beads during installation and improving the stability of the device for LED bead installation.

[0008] Preferably, a positioning block is fixed to the end of the connecting plate; a positioning groove is formed on the surface of the top plate; the positioning groove and the positioning block are correspondingly arranged; the inner wall of the positioning groove is inclined; when the connecting plate and the elastic sheet come into contact, the positioning block will also pass through the elastic sheet and move closer to the positioning groove until contact occurs. If the installation position of the LED bead is deviated, the end of the positioning block will come into contact with the inclined surface of the positioning groove, and then the positioning block will slide along the inclined surface of the positioning groove. The LED bead and the auxiliary plate will also move under the squeezing action of the positioning block and the positioning groove, so that the LED bead can be accurately installed on the base surface; through the cooperation of the positioning block and the positioning groove, the LED bead and the auxiliary plate will move under the friction action of the positioning block and the positioning groove, thereby realizing the positioning and correction of the LED bead installation position and improving the accuracy of the LED bead installation position.

[0009] Preferably, multiple support frames are symmetrically fixed to the bottom of the auxiliary plate; protective pads are fixed to the ends of the support frames; the protective pads are located between the support frames and the base; the LED beads are stacked before installation, and workers can place the light-emitting ends of the LED beads on top using the support frames, improving the stability of the stacked LED beads. Simultaneously, after the LED beads are installed on the base surface, the protective pads will contact the base before the support frames, reducing direct contact between the base and the support frames and minimizing damage to the base surface caused by friction. Through the combined action of the support frames and the protective pads, the contact area between the auxiliary plate and the base is increased, further improving the stability of the LED beads during installation. The protective pads also reduce direct contact between the auxiliary plate and the base, minimizing damage to the base surface during installation. By setting reflectors, the light emitted by the LED beads during illumination is reflected by the reflectors, expanding the propagation range of the light emitted by the LED beads and enhancing the lighting effect of the device.

[0010] Preferably, the base and auxiliary plate have multiple threaded holes on their surfaces; the surface of the threaded holes has a frustum structure; when the solder paste on the base surface is low, the operator can add solder paste to the connection between the base and the LED through the threaded holes, and can also fix adjacent threaded holes with bolts. Because the surface of the threaded holes has a frustum structure, bolt installation is more convenient, increasing the contact area between the auxiliary plate and the base, and improving the stability of the LED during operation; by setting the threaded holes, the operator can apply solder paste to the mounting area on the base through the threaded holes, improving the convenience of LED installation, and can also connect the LED, auxiliary plate and base through the threaded holes, further improving the stability of the LED during operation.

[0011] Preferably, a fixing ring is fixed to the surface of the auxiliary plate; the lamp bead is located inside the fixing ring; multiple reflectors are fixed to the inner wall of the fixing ring; the reflectors are arranged in a circumferential array; when the lamp bead emits light, the light will reach the inner wall of the fixing ring and be reflected by the reflectors. The reflectors will change the propagation path of the light, making the propagation path of the light emitted by the lamp bead wider, optimizing the diffusion range of the light emitted by the lamp bead, and improving the lighting effect of the device.

[0012] Preferably, the connecting assembly includes multiple locking plates; the locking plates and the base are hinged; the locking plates and the base are connected by a torsion spring; multiple fixing plates are fixed to the inner wall of the lamp body; the locking plates and fixing plates are correspondingly arranged; the fixing plates are located between the locking plates and the base; when the base needs to be installed on the inner wall of the lamp body, the locking plates can be pulled away from the base, and then the base can be moved to the fixing plate. At this time, the locking plates are released so that they rotate to the surface of the fixing plate under the action of the torsion spring. The above operation is repeated until all the locking plates are on the surface of the fixing plate. At this time, the base will be fixed by the friction between the locking plates and the fixing plates, realizing the quick fixing of the base by the device, simplifying the operation required for fixing the base, and shortening the time required for base installation; through the cooperation of the locking plates and fixing plates, the base can be quickly installed by the engagement of the locking plates and fixing plates, improving the convenience of the device for docking the base and the lamp body.

[0013] Preferably, a buffer pad is fixed to the surface of the card plate; the surface of the buffer pad has an arc-shaped structure; when the card plate and the fixed plate come into contact, the buffer pad will contact the fixed plate before the card plate. Because the surface of the buffer pad has a flexible structure, the buffer pad will absorb the impact generated when the card plate and the fixed plate come into contact, reducing the damage to the surfaces of the card plate and the fixed plate caused by the impact; by setting the buffer pad, the buffer pad will contact the fixed plate before the card plate, reducing the direct contact between the card plate and the fixed plate, and reducing the damage to the card plate and the fixed plate caused by the impact when the base is installed.

[0014] Preferably, the surface of the lamp body is bolted with multiple reinforcing plates; the reinforcing plates are equidistantly arranged; during transportation, the reinforcing plates can be fixed to the corners of the lamp body with bolts, improving the structural strength of the lamp body surface during handling. When the corners of the lamp body collide with the outside during handling, the reinforcing plates will contact the outside first, reducing direct contact between the lamp body and the outside world, and also reducing damage to the lamp body caused by collisions during transportation; by setting the reinforcing plates, the lamp body will contact the outside world first during transportation, which protects the lamp body and improves the convenience of transporting the lamp body.

[0015] Preferably, the threaded holes are symmetrically arranged; the threaded holes are circular in structure; because the threaded holes are symmetrically arranged, the operator can install bolts or apply solder paste to the threaded holes from any direction, improving the convenience of using the threaded holes. At the same time, because the threaded holes are circular in structure, the solder paste can be quickly sprayed through a nozzle or other tools, which also improves the convenience of the device for applying solder paste.

[0016] Preferably, the reflector is arranged in a circular array; the reflector is located on the top of the auxiliary plate; because the reflector is arranged in a circular array, it can uniformly reflect the light emitted by the lamp beads, thereby enhancing the auxiliary effect of the reflector on the lighting of the lamp beads.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The light-emitting principle of LED chips is based on the properties of semiconductor materials. When current flows through an LED chip, electrons and holes recombine at the PN junction, releasing energy as photons, thus emitting light. Specifically, the core of an LED chip is a PN junction composed of P-type and N-type semiconductors. In the P-type semiconductor, holes are the majority carriers, while in the N-type semiconductor, electrons are the majority carriers. When these two semiconductor materials are combined, a potential barrier is formed between them, preventing the free flow of electrons and holes. When a forward voltage is applied across the PN junction, the barrier decreases, and electrons and holes begin to diffuse towards each other. Electrons diffuse from the N-type semiconductor to the P-type semiconductor, recombine with holes, and release energy as photons, thus emitting light. Different semiconductor materials have different band structures and band gaps, therefore, they emit light of different wavelengths, resulting in different colors.

[0030] Specific implementation examples are given below.

[0031] Please see Figures 1 to 6As shown in the figure, an LED lighting device according to an embodiment of the present invention includes a lamp body 1; a base 12 is provided inside the lamp body 1; a connecting component 13 is provided on the surface of the base 12; the lamp body 1 and the base 12 are connected by the connecting component 13; a plurality of top plates 17 are fixedly connected to the surface of the base 12; a plurality of elastic sheets 18 are fixedly connected to the surface of the top plates 17; adjacent elastic sheets 18 have an arc-shaped structure and are symmetrically arranged; a plurality of elastic wires 19 are fixedly connected between adjacent elastic sheets 18; the base... A lamp bead 14 is provided in the middle of the base 12; an auxiliary plate 15 is fixedly connected to the middle of the lamp bead 14; the auxiliary plate 15 is insulated; a connecting plate 16 is symmetrically fixedly connected to the middle of the auxiliary plate 15; the ends of the connecting plate 16 and the elastic sheet 18 are correspondingly arranged; during maintenance, after removing the damaged lamp bead 14 from the surface of the base 12, the normal lamp bead 14 needs to be installed on the surface of the base 12. After the worker applies solder paste to the surface of the base 12, the lamp bead 14 can be installed on the surface of the base 12 by moving the auxiliary plate 15. When the auxiliary plate 15 is moved, the connection... The connecting plate 16 will also move accordingly. Before the LED bead 14 is installed, the connecting plate 16 will contact the elastic sheet 18 and be squeezed between the elastic sheets 18. The elastic sheet 18 will deform under the pressure and apply elastic force to the surface of the connecting plate 16. At the same time, the elastic wire 19 will also provide tension to the elastic sheet 18, reducing the deformation range of the elastic sheet 18. After the LED bead 14 is installed on the surface of the base 12, the connecting plate 16 will be in complete contact with the elastic sheet 18. At this time, the LED bead 14 and the auxiliary plate 15 will rub against each other between the connecting plate 16 and the elastic sheet 18. The base 12 is fixed in place, which facilitates the bonding of solder paste between the LED beads 14 and the base 12. The above operation is repeated until all LED beads 14 are installed. Finally, the base 12 is fixed inside the lamp body 1 by the connecting component 13. After the lamp body 1 is connected to the power supply, the LED beads 14 can emit light and provide external illumination. When the LED beads 14 are installed on the surface of the base 12, they are fixed by the elastic force of the elastic sheet 18 and elastic wire 19 on the connecting plate 16, which reduces the shaking caused by the installation of the LED beads 14 and improves the stability of the device for the installation of the LED beads 14.

[0032] Please see Figures 3 to 5As shown, a positioning block 2 is fixedly connected to the end of the connecting plate 16; a positioning groove 22 is provided on the surface of the top plate 17; the positioning groove 22 and the positioning block 2 are correspondingly arranged; the inner wall of the positioning groove 22 is inclined; when the connecting plate 16 and the elastic sheet 18 come into contact, the positioning block 2 will also pass through the elastic sheet 18 and move closer to the positioning groove 22 until it comes into contact. If the installation position of the lamp bead 14 is deviated, the end of the positioning block 2 will come into contact with the inclined surface of the positioning groove 22, and then the positioning block 2 will slide along the inclined surface of the positioning groove 22. The lamp bead 14 and the auxiliary plate 15 will also move under the squeezing action of the positioning block 2 and the positioning groove 22, so that the lamp bead 14 can be accurately installed on the surface of the base 12; through the cooperation of the positioning block 2 and the positioning groove 22, the lamp bead 14 and the auxiliary plate 15 will move under the friction action of the positioning block 2 and the positioning groove 22, so as to realize the positioning correction of the installation position of the lamp bead 14 and improve the accuracy of the lamp bead 14 during installation.

[0033] Please see Figure 4 As shown, multiple support frames 3 are symmetrically fixed to the bottom of the auxiliary plate 15; protective pads 32 are fixed to the ends of the support frames 3; the protective pads 32 are located between the support frames 3 and the base 12; the LED beads 14 are stacked before installation, and the workers can place the light-emitting ends of the LED beads 14 on top through the support frames 3 to improve the stability of the LED beads 14 when stacked. At the same time, after the LED beads 14 are installed on the surface of the base 12, the protective pads 32 will contact the base 12 before the support frames 3, and the protective pads 32 will reduce the direct contact between the base 12 and the support frames 3, reducing the damage to the surface of the base 12 caused by friction; through the cooperation of the support frames 3 and the protective pads 32, the contact area between the auxiliary plate 15 and the base 12 is increased, further improving the stability of the LED beads 14 during installation. At the same time, the protective pads 32 can also reduce the direct contact between the auxiliary plate 15 and the base 12, reducing the damage to the surface of the base 12 during installation.

[0034] Please see Figure 4 As shown, the base 12 and auxiliary plate 15 have multiple threaded holes 4 on their surfaces; the surface of the threaded holes 4 is a frustum structure; when the solder paste on the surface of the base 12 is low, the operator can add solder paste to the connection between the base 12 and the LED bead 14 through the threaded holes 4, and can also fix adjacent threaded holes 4 with bolts. Because the surface of the threaded holes 4 is a frustum structure, it makes bolt installation more convenient, increases the contact area between the auxiliary plate 15 and the base 12, and also improves the stability of the LED bead 14 during operation; by setting the threaded holes 4, the operator can apply solder paste to the mounting area on the base 12 through the threaded holes 4, improving the convenience of installing the LED bead 14, and can also connect the LED bead 14, auxiliary plate 15 and base 12 through the threaded holes 4, further improving the stability of the LED bead 14 during operation.

[0035] Please see Figure 4 As shown, a fixing ring 5 is fixedly attached to the surface of the auxiliary plate 15; the lamp bead 14 is located inside the fixing ring 5; multiple reflectors 52 are fixedly attached to the inner wall of the fixing ring 5; the reflectors 52 are arranged in a circumferential array; when the lamp bead 14 emits light, the light will reach the inner wall of the fixing ring 5 and be reflected by the reflectors 52. The reflectors 52 will change the propagation path of the light, making the propagation path of the light emitted by the lamp bead 14 wider, optimizing the diffusion range of the light emitted by the lamp bead 14, and improving the lighting effect of the device; by setting the reflectors 52, the light emitted by the lamp bead 14 when illuminating will be reflected by the reflectors 52, expanding the propagation range of the light emitted by the lamp bead 14 and enhancing the lighting effect of the device.

[0036] Please see Figure 2 and Figure 6 As shown, the connecting assembly 13 includes multiple retaining plates 6; the retaining plates 6 and the base 12 are hinged; the retaining plates 6 and the base 12 are connected by a torsion spring; multiple fixing plates 62 are fixedly connected to the inner wall of the lamp body 1; the retaining plates 6 and the fixing plates 62 are correspondingly arranged; the fixing plates 62 are located between the retaining plates 6 and the base 12; when the base 12 needs to be installed on the inner wall of the lamp body 1, the retaining plates 6 can be pulled away from the base 12, and then the base 12 can be moved to the fixing plate 62. At this time, the retaining plates 6 are released so that the retaining plates 6 are connected by a torsion spring. Under the action of the device, the base 12 rotates to the surface of the fixing plate 62. The above operation is repeated until all the clamping plates 6 are on the surface of the fixing plate 62. At this time, the base 12 will be fixed by the friction between the clamping plates 6 and the fixing plate 62, realizing the device to quickly fix the base 12, simplifying the operation required to fix the base 12, and shortening the installation time required for the base 12. Through the cooperation of the clamping plates 6 and the fixing plate 62, the base 12 can be quickly installed by the engagement of the clamping plates 6 and the fixing plate 62, improving the convenience of the device to connect the base 12 and the lamp body 1.

[0037] Please see Figure 6 As shown, a buffer pad 7 is fixedly attached to the surface of the card plate 6; the surface of the buffer pad 7 has an arc-shaped structure; when the card plate 6 and the fixing plate 62 come into contact, the buffer pad 7 will come into contact with the fixing plate 62 before the card plate 6. Because the surface of the buffer pad 7 has a flexible structure, the buffer pad 7 will absorb the impact generated when the card plate 6 and the fixing plate 62 come into contact, reducing the damage to the surfaces of the card plate 6 and the fixing plate 62 caused by the impact; by setting the buffer pad 7, the buffer pad 7 will come into contact with the fixing plate 62 before the card plate 6, reducing the direct contact between the card plate 6 and the fixing plate 62, and reducing the damage to the card plate 6 and the fixing plate 62 caused by the impact when the base 12 is installed.

[0038] Please see Figure 1As shown, multiple reinforcing plates 8 are bolted to the surface of the lamp body 1; the reinforcing plates 8 are equidistantly arranged; during transportation, the reinforcing plates 8 can be fixed to the corners of the lamp body 1 with bolts, improving the structural strength of the surface of the lamp body 1 during handling. When the corners of the lamp body 1 collide with the outside during handling, the reinforcing plates 8 will contact the outside first, reducing the direct contact between the lamp body 1 and the outside world, and also reducing the damage to the lamp body 1 caused by collision during transportation; by setting the reinforcing plates 8, the lamp body 1 will contact the outside world first during transportation, which will protect the lamp body 1 and improve the convenience of transporting the lamp body 1.

[0039] Please see Figures 1 to 6 As shown, the threaded holes 4 are symmetrically arranged; the threaded holes 4 have a circular structure; because the threaded holes 4 are symmetrically arranged, the operator can install bolts or apply solder paste to the threaded holes 4 from any direction, improving the convenience of using the threaded holes 4. At the same time, because the threaded holes 4 have a circular structure, the solder paste can be quickly sprayed through a nozzle or other tools, which also improves the convenience of the device for applying solder paste.

[0040] Please see Figures 1 to 6 As shown, the reflector 52 is arranged in a circular array; the reflector 52 is located on the top of the auxiliary plate 15; because the reflector 52 is arranged in a circular array, the reflector 52 can uniformly reflect the light emitted by the lamp bead 14, thereby enhancing the auxiliary effect of the reflector 52 on the illumination of the lamp bead 14.

[0041] Working principle: During maintenance, after removing the damaged LED 14 from the surface of the base 12, a normal LED 14 needs to be installed on the surface of the base 12. After applying solder paste to the surface of the base 12, the auxiliary plate 15 is moved to allow the LED 14 to be installed on the surface of the base 12. When the auxiliary plate 15 moves, the connecting plate 16 also moves accordingly. Before the LED 14 is fully installed, the connecting plate 16 will contact the elastic sheet 18 and squeeze between the elastic sheets 18. The elastic sheet 18 will deform under the compression and apply elastic force to the surface of the connecting plate 16. At the same time, the elastic wire 19 will also provide tension to the elastic sheet 18, reducing the deformation range of the elastic sheet 18. When the LED 14 is installed on the surface of the base 12, the connecting plate 16 will be in complete contact with the elastic sheet 18. At this time, the LED 14 and... The auxiliary plate 15 is fixed by the friction between the connecting plate 16 and the elastic sheet 18, which facilitates the bonding of solder paste between the LED bead 14 and the base 12. The above operation is repeated until all LED beads 14 are installed. Finally, after the base 12 is fixed inside the lamp body 1 by the connecting assembly 13, the lamp body 1 is connected to the power supply, and the LED beads 14 can emit light and provide external illumination. When the connecting plate 16 and the elastic sheet 18 come into contact, the positioning block 2 will also pass through the elastic sheet 18 and move closer to the positioning groove 22 until it makes contact. If the installation position of the LED bead 14 is deviated, the end of the positioning block 2 will come into contact with the inclined surface of the positioning groove 22. Then the positioning block 2 will slide along the inclined surface of the positioning groove 22, and the LED bead 14 and the auxiliary plate 15 will also be in contact with the positioning block 2 and the positioning groove. The LED 14 moves under the squeezing action of 22, allowing it to be accurately installed on the surface of the base 12. Before installation, the LEDs 14 are stacked, and workers can use the support frame 3 to position the light-emitting end of the LED 14 on top, improving the stability of the stacked LEDs 14. After the LEDs 14 are installed on the surface of the base 12, the protective pad 32 will contact the base 12 before the support frame 3, reducing direct contact between the base 12 and the support frame 3. When the solder paste on the surface of the base 12 is low, workers can add solder paste to the connection between the base 12 and the LED 14 through the threaded hole 4. Simultaneously, bolts can be used to fix adjacent threaded holes 4. Because the surface of the threaded hole 4 has a frustum structure, bolt installation is more convenient. The addition of the auxiliary plate 15 and... The contact area between the bases 12; when the lamp bead 14 emits light, the light will reach the inner wall of the fixing ring 5 and be reflected by the reflector 52. The reflector 52 will change the propagation path of the light, making the light emitted by the lamp bead 14 propagate more widely; when the base 12 needs to be installed on the inner wall of the lamp body 1, the clamping plate 6 can be pulled to move the clamping plate 6 away from the base 12, and then the base 12 can be moved to the fixing plate 62. At this time, the clamping plate 6 is released so that the clamping plate 6 rotates to the surface of the fixing plate 62 under the action of the torsion spring. The above operation is repeated until all the clamping plates 6 are on the surface of the fixing plate 62. At this time, the base 12 will be fixed by the friction between the clamping plate 6 and the fixing plate 62, realizing the quick fixation of the base 12 by the device and simplifying the operation required to fix the base 12;When the clamping plate 6 and the fixing plate 62 come into contact, the buffer pad 7 will contact the fixing plate 62 before the clamping plate 6. Because the surface of the buffer pad 7 is a flexible structure, it absorbs the impact generated when the clamping plate 6 and the fixing plate 62 come into contact. During transportation, the reinforcing plate 8 can be fixed to the corner of the lamp body 1 with bolts, improving the structural strength of the lamp body 1 surface during handling.
