Description

[0001] The present application relates to the technical field of LED lamps, in particular to a multifunctional LED lamp. BACKGROUND

[0002] LED lamps have been widely used in various occasions due to their energy-saving, long-life, environmental protection and other advantages. However, most of the existing LED lamps have the following technical defects:

[0003] Fixed illumination range: The illumination angle and range of traditional LED lamps are usually fixed at the factory, and cannot be flexibly adjusted according to the use scene (such as local key lighting or large-area flood lighting), which limits the applicability.

[0004] Fixed number of lamp beads: The brightness of the lamp is bound to the number of lamp beads, and users cannot increase or decrease the number of lamp beads to change the brightness or replace the light color according to their own needs, resulting in poor product flexibility, and damage to a single lamp bead may affect the use of the entire lamp.

[0005] Poor heat dissipation performance: The life and light efficiency of LED lamp beads are directly related to heat dissipation, and the existing integrated lamp dissipation structure is often single, and heat is easy to accumulate, which leads to accelerated light decay and shortens the service life of the lamp.

[0011] As preferred, a vertical limiting frame and two horizontal limiting frames are fixed on the outside of the lamp holder, the vertical limiting frame and the two horizontal limiting frames have an arc, and the filter sheet is embedded in the inside of the vertical limiting frame and the two horizontal limiting frames.

[0012] Preferably, the inner side of the fixing seat is provided with a limiting groove, and a rotatable limiting block is provided in the limiting groove.

[0017] 1. In use, LED beads can be placed into several lamp slots, with two conductive leads embedded in two slots respectively, and the conductive leads in contact with the power socket. When the power socket is energized, the LED beads will be lit, thus achieving the illumination function of the LED lamp. After the LED beads are placed in the lamp slots, the fixing components can be used to fix the LED beads, ensuring stable lighting performance after installation. Conversely, if the LED lamp needs to be repaired, simply separate the fixing components from the LED beads, remove the damaged LED beads from the lamp slot for replacement, and then place the new LED beads into the lamp slot for fixing. This further improves the maintenance and repair efficiency of LED beads. Compared to traditional LED beads that are directly soldered into the lamp holder and require tools such as soldering irons to remove and replace, this invention can quickly repair and replace individual LED beads, solving the problem of inconvenient maintenance and repair, and further improving the practicality of LED lamps.

[0018] 2. By rotating the adjusting screw, the threaded seat can move up and down along the screw, which in turn causes the outer shell to slide up and down along the inner shell. When the threaded seat separates from the adjusting screw, the lamp housing can be disassembled, allowing for the inspection and replacement of the LED beads. Similarly, the position of the threaded seat on the adjusting screw can be used to adjust the vertical position of the outer shell, thereby adjusting the position of the spotlight cover. Therefore, the illumination range emitted by the LED lamp can be flexibly adjusted. Users can achieve seamless switching between spotlight (small area high brightness) and floodlight (large area uniform illumination) without replacing the lamp, meeting the needs of diverse scenarios.

[0019] 3. Several heat dissipation holes ensure airflow between the upper and lower parts of the lamp holder, and the heat dissipation grooves quickly dissipate the heat generated by the LED lamp, ensuring that the LED lamp is always kept within a safe temperature range, greatly extending the life of the lamp and ensuring the stability of the light effect. At the same time, the filter can block dust, which can achieve good heat dissipation and dust prevention. Users only need to clean the filter regularly to ensure the stable heat dissipation effect of the LED lamp. Attached Figure Description

[0029] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of the present invention should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0030] like Figures 1 to 8 As shown, a multifunctional LED lamp includes a base 1, a lamp holder 2, and a lamp housing 3, which are detachably connected from top to bottom. A hollow sleeve 4 passes through the lower end of the lamp holder 2, and two support plates 5 are fixed on the hollow sleeve 4. The two support plates 5 abut against the upper and lower ends of the lamp holder 2, respectively. A junction box 6 is connected to the lower end of the hollow sleeve 4, and several lighting tubes 7 are connected to the outside of the junction box 6. Several lamp slots 8 are provided on each lighting tube 7, and LED beads 9 are placed in each of the lamp slots 8. Two conductive tubes are connected to the outside of the LED beads 9. The LED lamp beads 9 are placed into the several lamp slots 8. At the same time, the two conductive pins 10 are embedded in the two placement slots 11 and are in contact with the two conductive pins 12. When in use, the LED lamp beads 9 can be placed into the several lamp slots 8. The two conductive pins 10 can be embedded into the two placement slots 11 and are in contact with the conductive pins 12. When the conductive pins 12 are energized, the LED lamp beads 9 can be lit, thereby realizing the lighting function of the LED lamp.

[0031] Several sets of fixing components 13 are respectively provided on several lighting tubes 7. The fixing components 13 are respectively engaged with the lamp groove 8 and respectively abut against the LED beads 9 inside the lamp groove 8. When the LED beads 9 are placed into the lamp groove 8, the fixing components 13 can fix the LED beads 9 to ensure the stable lighting performance of the LED beads 9 after installation. Conversely, if the LED lamp needs to be repaired, it is only necessary to separate the fixing components 13 from the LED beads 9, remove the damaged LED beads 9 from the lamp groove 8 and replace them. Then the new LED beads 9 can be placed into the lamp groove 8 and fixed. This further improves the maintenance and repair efficiency of the LED beads 9. Compared with the traditional method of directly soldering the LED beads 9 into the lamp holder 2 and requiring the use of tools such as soldering irons to remove and replace them, this invention can quickly repair and replace individual LED beads 9, solve the problem of inconvenient maintenance and repair, and further improve the practicality of the LED lamp.

[0032] Each fixing component 13 includes a retaining ring 22. Several sliding cylinder seats 23 are fixedly mounted on the lighting tube 7. A slidable pressure rod 24 passes through each sliding cylinder seat 23. A retaining spring 25 is fixedly mounted inside the sliding cylinder seat 23, with the other end of the retaining spring 25 abutting against the bottom of the pressure rod 24. The retaining ring 22 is fixedly connected to the other end of the pressure rod 24. Two retaining blocks 26 are fixedly mounted on the outer side of each retaining ring 22, and the two retaining blocks 26 are respectively adapted to the placement groove 11. By pulling down the pressure rod 24, the pressure rod 24 can slide downwards along the sliding cylinder seat 23. At this time, the retaining spring 25 is stretched and generates elasticity. The force can simultaneously separate the clamping ring 22 from the lamp slot 8, and the clamping spring 25 has a certain torsional shape. While pulling down the pressure rod 24, it can also rotate it to a certain extent. Then, the LED bead 9 can be placed into the lamp slot 8, and the pressure rod 24 will return to its initial position through the reset action of the clamping spring 25. This allows the clamping ring 22 to be pushed into the lamp slot 8 again, thus achieving the contact and fixation of the LED bead 9. At the same time, the clamping blocks 26 at both ends can enter the placement slot 11 to attach and fix the two conductive pins 10. Finally, the LED bead 9 can be quickly removed, replaced, and fixed.

[0033] The lower end of the lamp holder 2 is connected to the inner shell 14. The lamp housing 3 includes a condenser 15 and an outer shell 16, with the outer shell 16 fixed to the upper end of the condenser 15. The outer shell 16 is slidably fitted onto the outside of the inner shell 14. A fixing seat 17 is fixed to one side of the lamp holder 2, and a rotatable adjusting screw 18 passes through the fixing seat 17. A threaded seat 19 is fixed to the outside of the outer shell 16, and the lower end of the adjusting screw 18 passes through the threaded seat 19. By rotating the adjusting screw 18, the threaded seat 19 can move up and down along the adjusting screw 18, thereby driving the outer shell 16 along the inner shell 14. By sliding up and down, when the threaded seat 19 separates from the adjusting screw 18, the lamp housing 3 can be disassembled, thereby enabling the inspection and replacement of the LED beads 9. Similarly, the position of the threaded seat 19 on the adjusting screw 18 can be used to adjust the up and down position of the housing 16, thereby adjusting the position of the spotlight cover 15. Therefore, the illumination range emitted by the LED lamp can be flexibly adjusted. Users can achieve seamless switching between spotlight (small area high brightness) and floodlight (large area uniform illumination) without replacing the lamp, meeting the needs of diverse scenarios.

[0034] The inner side of the fixed base 17 is provided with a limiting groove 33, and a rotatable limiting block 34 is provided in the limiting groove 33. The limiting block 34 is fixedly connected to the adjusting screw 18. A protrusion 35 is fixedly provided on the other side of the lamp holder 2. A guide rod 36 is connected to the lower end of the protrusion 35. A guide seat 37 is fixedly provided on the outer side of the outer shell 16, and the guide rod 36 passes through the guide seat 37. When the adjusting screw 18 is rotated, the limiting block 34 can rotate in the limiting groove 33. Therefore, the limiting block 34 can provide a limiting support for the adjusting screw 18 to ensure that the adjusting screw 18 can rotate in place. When the outer shell 16 moves up and down along the inner shell 14, the guide seat 37 can also slide up and down along the guide rod 36. Therefore, the movement trajectory of the lampshade can be more horizontal and straight, thereby achieving precise adjustment of the illumination range and ensuring more accurate installation position of the lampshade.

[0035] The lamp holder 2 is also provided with a heat dissipation groove on the outside, and the heat dissipation groove is connected to the inside of the lamp holder 2. A detachable filter 20 is connected to the outside of the heat dissipation groove. The lamp holder 2 is provided with several heat dissipation holes 21, which are connected to the upper and lower ends of the lamp holder 2. The heat dissipation holes 21 can ensure the airflow between the upper and lower parts of the lamp holder 2, and the heat dissipation groove can quickly dissipate the heat generated by the LED lamp to ensure that the LED lamp is always kept within a safe temperature range, which greatly extends the service life of the lamp and ensures the stability of the light effect. At the same time, the filter 20 can block dust, which can achieve good heat dissipation and dust prevention performance at the same time. Users only need to clean the filter 20 regularly to ensure the stable heat dissipation effect of the LED lamp. A vertical limiting frame 31 and two horizontal limiting frames 32 are fixedly provided on the outer side of the lamp holder 2. The vertical limiting frame 31 and the two horizontal limiting frames 32 are all curved, and the outer side of the filter 20 is respectively embedded in the inner side of the vertical limiting frame 31 and the two horizontal limiting frames 32. The vertical limiting frame 31 and the two horizontal limiting frames 32 can fix the filter 20. Similarly, the filter 20 can be pulled out from the vertical limiting frame 31 and the two horizontal limiting frames 32 for disassembly.

[0036] Several hollow sleeves 41 are fixedly provided at the upper end of the base 1, and several fixing screws 42 are passed through the lower end of the base 1. The fixing screws 42 are respectively passed through the inner side of the hollow sleeves 41. When installing the LED light, simply drill holes at the marked positions on the wall, then insert expansion tubes into the holes, and pass the fixing screws 42 through the hollow sleeves 41. Then, the top of the fixing screws 42 can be screwed into the expansion tubes to achieve contact between the hollow sleeves 41 and the wall, thereby achieving the fixed installation of the base 1.

[0037] The top of the lamp holder 2 is connected to several rotating blocks 27, each of which has a fixed arc. The lower end of the base 1 is provided with several rotating slots 28, which are respectively adapted to the rotating blocks 27. A fixing screw 29 is provided on the outside of the base 1. Each of the rotating blocks 27 is provided with a threaded hole 30, and the top of the fixing screw 29 passes through the threaded hole 30. After the base 1 is fixed to the wall, the lamp holder 2 can be connected to the base 1, and the rotating blocks 27 on the lamp holder 2 can be inserted upwards into the rotating slots 28. In step 8, when the lower end of the base 1 is in contact with the upper end of the lamp holder 2, the lamp holder 2 can be rotated, so that the protruding part of the rotating block 27 can be inserted into the deepest part of the rotating groove 28, thus fixing the base 1 and the lamp holder 2. Then, the fixing screw 29 can be screwed into the outside of the base 1, and the top of the fixing screw 29 can be screwed into the threaded hole 30, thereby firmly fixing the rotating block 27 and the rotating groove 28, preventing the rotating block 27 from accidentally coming out of the rotating groove 28, and further improving the installation stability of the LED light.

[0038] A driver module 38 is installed on the upper end of the lamp holder 2. The inner sides of several lighting tubes 7 are respectively connected to wire harness cavities 39. Several wire harness cavities 39 are respectively connected to the junction box 6 and the hollow sleeve 4. Several power sockets 12 are respectively connected to the wire harness cavities 39 through wires. A wire harness through groove 40 is opened on the base 1. The wire harness through groove 40 facilitates the insertion of the main power line, so as to connect the driver module 38 to the main power line. Through the central control sleeve, junction box 6 and several wire harness cavities 39, the wires can be easily inserted, and the wires can be connected to several power sockets 12 respectively. The several power sockets 12 are connected in parallel, that is, when a single LED bead 9 is damaged, it will not affect the normal use of the overall LED lamp. The model of the driver module 38 and the driving connection method between it and the several power sockets 12 are existing technologies, so they will not be described in detail.

[0039] Both the clamping ring 22 and the clamping block 26 are made of silicone rubber, which can ensure the insulation between them and the LED beads 9 and the power socket 12. The inner side of the focusing cover 15 is coated with polycarbonate, which can make the LED light focusing effect better.

[0040] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
