They offer advantages such as superior light quality, low energy consumption, long lifespan, and versatility in various applications, making them widely used in homes, businesses, and offices. Existing LED ceiling lights typically consist of a single, integrated structure, with the LED chips and control circuit board sealed within the housing. When the LED chips or control circuit board fail due to prolonged use, the entire LED ceiling light usually needs to be replaced. Therefore, developing an LED ceiling light that only requires partial replacement when the LED chips or control circuit board fail, thus saving on replacement costs, is of significant practical importance.

[0030] See Figures 1 to 13The LED ceiling light shown includes a ceiling light body 11, a face ring assembly 12, and a splicing assembly 13. The splicing assembly 13 is disposed on the lower side of the face ring assembly 12. The ceiling light body 11 and the splicing assembly 13 are detachably connected. Mounting seats 14 are provided on both sides of the face ring assembly 12, and bracket assemblies 15 are provided on both mounting seats 14. The ceiling light body 11 includes a light box 17. A lens 22 is provided on the top of the light box 17. The lens 22 can be directly purchased from the market. An aluminum substrate 18 and a control circuit board 20 are provided inside the light box 17. The control circuit board 20 is disposed on the lower side of the aluminum substrate 18. A pin header assembly 21 is provided between the aluminum substrate 18 and the control circuit board 20. LED beads 19 are provided on the aluminum substrate 18, and wires 16 are provided on the control circuit board 20. Two splicing strips 27 are provided on the outer wall of the lamp box 17, and each splicing strip 27 has a snap-fit protrusion 28. The two splicing strips 27 are centrally symmetrically arranged and are fixed to the lamp box 17 at an angle. The splicing assembly 13 is rotatably mounted between two mounting bases 14. A retaining ring 37 is provided on the splicing assembly 13, and arc-shaped limiting strips 38 are provided on both sides of the retaining ring 37. Two... The splicing protrusion 39 has a groove 40 corresponding to the snap-fit protrusion 28. When the ceiling light body 11 is assembled with the splicing component 13, the top of the light box 17 extends into the inside of the splicing component 13. The splicing strip 27 is located between the splicing protrusion 39 and the retaining ring 37. The snap-fit protrusion 28 on the splicing strip 27 is engaged in the groove 40 on the splicing protrusion 39, so that the light box 17 and the splicing component 13 are connected together, realizing the assembly of the ceiling light body 11 and the splicing component 13. At this time, two arc-shaped limiting strips 38 are respectively blocked on both sides of the light box 17, thereby preventing the light box 17 from shifting to the sides, and thus strengthening the ceiling light. The stability of the assembly of the main body 11 and the splicing component 13; by turning the light box 17, the splicing strip 27 on the side wall of the light box 17 rotates, thereby separating the snap-fit protrusion 28 from the groove 40, and the splicing strip 27 disengages from the splicing protrusion 39 and the retaining ring 37. Then the ceiling light main body 11 and the splicing component 13 can be disassembled. When the LED beads 19 or the control circuit board 20 in the ceiling light main body 11 are damaged, only the ceiling light main body 11 needs to be removed for replacement. The face ring component 12, splicing component 13, mounting base 14 and bracket component 15 do not need to be replaced, thereby saving the replacement cost of the LED ceiling light.
[0031] The control circuit board 20 is equipped with electronic components such as a rectifier bridge, diodes, capacitors, inductors, resistors, multi-position switches, PWM dimming chips, MOSFETs, RF receivers, and fuses. Four sets of LED beads 19 are set on the aluminum substrate 18. The LED beads 19 are connected to the circuit on the aluminum substrate 18. The pin header assembly 21 connects the circuit on the aluminum substrate 18 with the circuit on the control circuit board 20. The electronic components on the control circuit board 20, together with the aluminum substrate 18, LED beads 19, and pin header assembly 21, constitute a circuit structure with AC input, rectification and filtering, constant current drive, dimming control, and LED light emission as the core architecture. The specific circuit structure is a technical means commonly used by those skilled in the art and is existing technology, so it will not be described in detail here.
[0032] Of the four sets of LED beads on the aluminum substrate 18, two sets of LED beads are 3000K warm yellow temperature, and the other two sets are 6500K cool white temperature. The PWM dimming chip on the control circuit board 20 controls the brightness ratio of the 3000K LED beads and the 6500K LED beads, thereby realizing the color temperature adjustment of the LED ceiling light.
[0033] By transmitting an RF signal to the RF receiver on the control circuit board 20 using an RF remote control, the PWM dimming chip can be remotely controlled, thereby controlling the color temperature adjustment of the LED ceiling light.
[0034] The bottom of the light box 17 has a strip-shaped groove, in which a switch cap slides. The switch cap is connected to a multi-position switch on the control circuit board 20. By tossing the switch cap, the position of the multi-position switch can be adjusted. The multi-position switch can control the PWM dimming chip, thereby controlling the color temperature of the LED ceiling light. Each position of the multi-position switch corresponds to a color temperature. Users can toss the multi-position switch to the corresponding position according to their color temperature preference or scene requirements, so that the default color temperature when the LED is lit matches the user's preference or scene requirements. This solves the problem that if the default color temperature of the LED ceiling light does not match the user's preference or scene requirements, the color temperature needs to be adjusted with an RF remote control every time the light is turned on, which is inconvenient.
[0035] One end of the wire 16 is connected to the circuit on the control circuit board 20. The bottom of the light box 17 has a through hole corresponding to the wire 16. The other end of the wire 16 passes through the through hole. The wire 16 is connected to the power supply through an external power cord to power the LED ceiling light. A certain length of power cord is reserved to avoid damaging the power cord when disassembling the LED ceiling light.
[0036] Furthermore, the splicing protrusion 39 includes a splicing part 42 and a blocking part 43. The splicing assembly 13, the retaining ring 37, the splicing part 42 and the blocking part 43 are an integrated structure. The splicing part 42 is disposed on the inner wall of the splicing assembly 13, and the blocking part 43 is disposed at one end of the splicing part 42. One end of the blocking part 43 is connected to the splicing part 42, and the other end of the blocking part 43 is connected to the retaining ring 37. One side of the splicing part 42 is inclined, and the groove 40 is disposed on the inclined side of the splicing part 42.
[0037] The inclined edge of the splicing part 42 corresponds to the inclined angle of the splicing strip 27 on the side wall of the light box 17. When splicing the ceiling light body 11 and the splicing component 13, the splicing strip 27 extends into the gap between the splicing part 42 and the retaining ring 37. The side of the splicing strip 27 with the snap-fit protrusion 28 slides against the inclined edge of the splicing part 42 until the snap-fit protrusion 28 is engaged in the groove 40, thus completing the splicing of the ceiling light body 11 and the splicing component 13. The blocking part 43 blocks one side of the splicing strip 27 to prevent the splicing strip 27 from passing directly through the gap between the splicing part 42 and the retaining ring 37 due to excessive twisting of the light box 17. When disassembling the ceiling light body 11, twist the light box 17 in the opposite direction to separate the snap-fit protrusion 28 from the groove 40, and the splicing strip 27 will come out from the gap between the splicing part 42 and the retaining ring 37. The ceiling light body 11 can then be removed from the splicing assembly 13. The operation is simple and convenient.
[0038] Furthermore, the pin header assembly 21 includes a fixing block 44, which is fixed to the aluminum substrate 18. Multiple pin headers 45 are fixedly disposed on the fixing block 44. One end of each pin header 45 extends upward and abuts against the lens 22, while the other end extends downward and is bent into an L-shape. The L-shaped end of the pin header 45 is connected to the control circuit board 20. Each pin header 45 has a conductive strip 46 on one side, with one end connected to the pin header 45 and the other end connected to the aluminum substrate 18. The lower end of the pin header 45 is connected to the circuitry on the control circuit board 20. The conductive strip 46 connects the pin header 45 and the circuitry on the aluminum substrate 18, thus enabling communication between the circuitry on the aluminum substrate 18 and the control circuit board 20. Simultaneously, the aluminum substrate 18 is separated from the control circuit board 20, preventing direct contact and thus isolating the heat generated by both during prolonged use, preventing mutual interference and accelerated aging, and extending service life.
[0039] Furthermore, the face ring assembly 12 includes a face ring 29 and a barrier 30. The face ring 29 has a circular window, and the barrier 30 is located at the edge of the circular window on the face ring 29. Two mounting seats 14 are symmetrically arranged on the barrier 30. The face ring 29, the barrier 30, and the two mounting seats 14 are an integrated structure. The mounting seat 14 has a slot 31, and a snap-fit piece 33 is provided on one side wall of the slot 31. The snap-fit piece 33 has two triangular snap-fit blocks 32. A U-shaped groove is opened on the side wall of the slot 31 to form the snap-fit piece 33 on the side wall of the slot 31. The triangular snap-fit blocks 32 are fixed on the snap-fit piece 33.
[0040] Furthermore, the bracket assembly 15 includes a spring frame 24, one end of which is inserted into the slot 31, and the other end of the spring frame 24 is provided with a rubber sleeve 25. The middle part of the spring frame 24 is a spring, and the two ends of the spring frame 24 are U-shaped brackets. The U-shaped bracket at one end of the spring frame 24 is inserted into the slot 31, and the triangular locking block 32 locks the U-shaped bracket at this end of the spring frame 24, so that the spring frame 24 is stably installed on the mounting base 14.
[0041] Furthermore, one end of the rubber sleeve 25 is provided with an end head 35, and the other end of the rubber sleeve 25 is provided with a slot 36. One end of the spring frame 24 is inserted into the slot 36, and the rubber sleeve 25 is fitted onto one end of the spring frame 24. The cross-section of the end head 35 is trapezoidal, and the inclined part of the end head 35 is provided with anti-slip texture. When the rubber sleeve 25 is moved, the operator's fingers fit against the anti-slip texture on the inclined surface of the end head 35, thereby avoiding slippage when moving the rubber sleeve 25.
[0042] Furthermore, a shaft head 34 is fixed on one side of the mounting base 14, and a shaft cylinder 41 corresponding to the shaft head 34 is provided on the side wall of the splicing assembly 13. The shaft head 34 is rotatably connected to the corresponding shaft cylinder 41. The two shaft cylinders 41 on the side wall of the splicing assembly 13 are rotatably connected to the shaft heads 34 on the two mounting bases 14 respectively. When the ceiling light body 11 is spliced with the splicing assembly 13, the splicing assembly 13 is turned so that the ceiling light body 11 is deflected accordingly, thereby adjusting the illumination angle of the LED beads 19 in the ceiling light body 11, and thus adjusting the lighting angle according to actual needs.
[0043] Furthermore, a boss 26 is provided on the inner wall of the lamp box 17, and the aluminum substrate 18 abuts against the boss 26. The inner diameter of the opening of the lamp box 17 gradually decreases from top to bottom. The lens 22 is sandwiched between the splicing assembly 13 and the inner wall of the lamp box 17. The aluminum substrate 18 is placed on the boss 26, and the top of the pin 45 abuts against the bottom of the lens 22. Correspondingly, the aluminum substrate 18 is tightly pressed against the boss 26, thereby making the aluminum substrate 18 stably set inside the lamp box 17.
[0044] Furthermore, two limiting seats 23 are fixedly installed on the bottom wall inside the lamp box 17. The limiting seats 23 have a U-shaped structure. The two sides of the control circuit board 20 are respectively inserted into the two limiting seats 23. The pin header assembly 21 will have a certain abutting effect on the control circuit board 20. The limiting seats 23 restrict the position of the control circuit board 20, so that the control circuit board 20 is stably installed in the lamp box 17 and prevents the control circuit board 20 from shifting position.
[0045] The working principle of this utility model is as follows: Holes for installing LED ceiling lights are pre-set in the ceiling. The diameter of the holes is smaller than the outer diameter of the face ring assembly 12 and larger than the distance between the two mounting bases 14. When installing the LED ceiling light on the ceiling, first, the wire 16 is inserted into the pre-set hole in the ceiling, connecting the wire 16 to the power line arranged in the pre-set hole. Then, the LED ceiling light is inverted, and the rubber sleeve 25 is rotated around the spring part of the spring frame 24. The spring part of the spring frame 24 accumulates elastic potential energy until the rubber sleeve 25 is in the state shown in the face ring assembly 12. At this time, the distance between the ends of the two rubber sleeves 25 is... After the diameter of the pre-set hole on the ceiling is smaller than the diameter of the hole, the LED ceiling light can be placed in the pre-set hole on the ceiling. At this time, the face ring 29 is in the pre-set hole on the ceiling and the face ring 29 is close to the ceiling. The ceiling light body 11, splicing component 13, mounting base 14, bracket component 15 and enclosure 30 are all in the pre-set hole on the ceiling. The rubber sleeve 25 of the bracket component 15 is released, and the spring part of the spring frame 24 releases elastic potential energy to make the rubber sleeve 25 rotate, so that the ends of the two rubber sleeves 25 abut against the inner side of the ceiling, thereby making the LED ceiling light stuck in the pre-set hole, so that the LED ceiling light is stably installed on the ceiling.
[0046] When the LED bulb 19 or control circuit board 20 of the LED ceiling light is damaged, pull the edge of the face ring 29 to create a gap between the edge of the face ring 29 and the ceiling. Then, insert your finger into this gap, hook the face ring 29 and pull it downwards. As the LED ceiling light moves downwards, the rubber sleeve 25 is pushed by the inner wall of the ceiling until the spring bracket 24 and the rubber sleeve 25 are in the state shown in the face ring assembly 12. After that, remove the LED ceiling light from the preset hole in the ceiling, and then disconnect the wire 16 from the power cord to remove the LED ceiling light from the ceiling. Then, twist... The light box 17 rotates, and the splicing strip 27 on the light box 17 disengages from the gap between the splicing part 42 and the retaining ring 37 during the rotation. The snap-fit protrusion 28 on the splicing strip 27 separates from the groove 40, thereby separating the light box 17 from the splicing assembly 13. The ceiling light body 11, including the damaged LED beads 19 or control circuit board 20, can then be removed from the splicing assembly 13. Afterwards, the face ring assembly 12, splicing assembly 13, mounting base 14 and bracket assembly 15 can be retained, and only the ceiling light body 11 needs to be replaced, thereby saving the replacement cost of the LED ceiling light.
[0047] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
