Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an embedded lighting module based on variable color temperature LED crafts. Background Technology

[0002] LED lighting has the advantages of high energy efficiency and long lifespan, thus rapidly replacing existing lighting equipment with fluorescent lamps, incandescent lamps, and other light sources. Compared with traditional incandescent and fluorescent lamps, LEDs have many advantages, mainly in terms of energy consumption, multifunctionality, and control flexibility. This allows for the achievement of a wide variety of effects, and therefore LEDs are increasingly widely used as light sources.

[0003] Patent CN103052844A discloses an LED lighting module and a lighting lamp using the LED lighting module. The module includes an LED module with multiple LED elements arranged on a circuit board having a connector plug for connecting to a power source on one side, and the module being formed by a surface light emitter. A light diffusion cover covers the upper part of the LED module in a semi-cylindrical shape and has one or more flanges formed on the left and right sides respectively. A heat sink made of metal material is attached to the bottom of the LED module and has a lower edge inserted into the light diffusion cover and fixed to the outer periphery of the lower end of the light diffusion cover. The LED module, the light diffusion cover and the heat sink are integrally combined.

[0004] The aforementioned lighting fixture has multiple LED lighting modules installed in a housing cover containing a built-in power module, and is secured with a lower cover to form a lighting fixture that is not restricted by the direction of use, promotes smooth heat dissipation, and can distribute the light source 180 degrees. However, the lighting brightness of each area is the same, and the position of the emitting LED lighting modules is fixed. It is not convenient to concentrate the light source to a certain area according to the user's needs to increase the brightness of the concentrated lighting. It cannot be flexibly adjusted during use, which increases energy consumption. Utility Model Content

[0005] The purpose of this invention is to provide an embedded lighting module based on variable color temperature LED crafts, in order to solve the problem mentioned in the background art that the position of the LED lighting module is not adjustable, and it is impossible to concentrate the light source in one area to increase the brightness according to the usage requirements, resulting in excessive energy consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an embedded lighting module based on variable color temperature LED crafts, comprising a transparent outer cover, a first bracket fixed to the top of the transparent outer cover, a rotating shaft rotatably connected to the middle position of the first bracket, a central column provided inside the transparent outer cover, and the central column being fixedly connected to the inner bottom surface of the transparent outer cover, a horizontal plate rotatably connected to the central column, an annular groove being formed on the outer surface of the central column, and the annular groove matching the horizontal plate, an LED light board being fixed at the end of the horizontal plate, and two LED light boards symmetrically arranged about the center line of the horizontal plate, with LED beads evenly installed on the outer side of the LED light board.

[0007] Furthermore, a connecting plate is fixed on the horizontal plate, a rotating plate is fixed on the outside of the connecting plate, a rotating base is fixed on the other end of the rotating plate, and the rotating base is rotatably connected to the central column. The rotating shaft is slidably connected to the rotating base, and an arc-shaped telescopic rod is fixed on each of the connecting plates.

[0008] Furthermore, a fixing rod is fixed to another connecting plate, and the other end of the fixing rod is fixedly connected to the central column.

[0009] Furthermore, a knob is coaxially fixed to the top of the rotating shaft, a limiting ring is fixed to the middle position of the first bracket, the rotating shaft and the limiting ring are slidably connected, a limiting block is fixed on the rotating shaft, and two limiting grooves are opened on the inner wall of the limiting ring, and the limiting grooves match the limiting blocks.

[0010] Furthermore, a lifting plate is provided above the first bracket, the rotating shaft is rotatably connected to the lifting plate, a support ring is fixed on the rotating shaft, and the support ring matches the lifting plate.

[0011] Furthermore, guide rods are provided at both ends of the lifting plate, and the lifting plate and the guide rods are slidably connected. The bottom end of the guide rod is fixedly connected to the first bracket, and the top end of the guide rod is fixedly connected to the second bracket.

[0012] Furthermore, a spring is nested on the outside of the guide rod, one end of the spring is fixedly connected to the lifting plate, and the other end is fixedly connected to the second bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This embedded lighting module based on variable color temperature LED craftsmanship works by rotating a knob. The rotating shaft fixed on the knob rotates the base, and the rotating plate fixed on the base acts on the connecting plate. The connecting plate rotates around the axis of the central column and pushes the arc-shaped telescopic rod until the arc-shaped telescopic rod is retracted to its shortest length. The force of the connecting plate on the arc-shaped telescopic rod is transmitted to the second connecting plate, which in turn rotates the LED light panels on each connecting plate together, making it easier to concentrate the light source, improve brightness, and meet the needs of users. Furthermore, when the LED panels are evenly distributed, the limiting block is locked in the first limiting groove, which restricts the rotation of the shaft. When the knob is lifted upwards, the shaft and knob rise to a specified height, and the limiting block disengages from the first limiting groove, releasing the rotation restriction of the shaft. Then, the knob is rotated, and when it reaches a specified angle, it is released. Under the rebound of the spring, the lifting plate lowers the shaft, and the limiting block on the shaft is locked into the second limiting groove, thus re-restricting the rotation of the shaft and facilitating control of the shaft's rotation, thereby completing the adjustment of the LED panel position.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figures 1-4 This utility model provides the following technical solution: an embedded lighting module based on variable color temperature LED crafts, including a transparent outer cover 1, a first bracket 2 fixed to the top of the transparent outer cover 1, a rotating shaft 3 rotatably connected to the middle position of the first bracket 2, a central column 4 disposed inside the transparent outer cover 1, and the central column 4 fixedly connected to the inner bottom surface of the transparent outer cover 1, a horizontal plate 5 rotatably connected to the central column 4, an annular groove 6 opened on the outer surface of the central column 4, and the annular groove 6 matching the horizontal plate 5, and an LED light board fixed at the end of the horizontal plate 5. 7. Two horizontal plates 5 are symmetrically arranged about the center line of the LED light panel 7. LED beads 8 are evenly installed on the outer side of the LED light panel 7. A connecting plate 9 is fixed on the horizontal plate 5. A rotating plate 10 is fixed on the outer side of the connecting plate 9. A rotating base 22 is fixed on the other end of the rotating plate 10. The rotating base 22 is rotatably connected to the central column 4. The rotating shaft 3 is slidably connected to the rotating base 22. An arc-shaped telescopic rod 11 is fixed on each pair of connecting plates 9. A fixing rod 12 is fixed on the other connecting plate 9. The other end of the fixing rod 12 is fixedly connected to the central column 4.

[0018] LED light panels 7 are evenly distributed within the transparent outer cover 1. Multiple LED beads 8 are evenly embedded in each LED light panel 7, ensuring uniform light distribution and providing illumination for the user. When the user needs to concentrate the LED light panels 7 together to increase brightness, they can rotate knob 13. A rotating shaft 3 is fixed to knob 13, causing a rotating base 22 to rotate synchronously. A rotating plate 10 is fixed to the rotating base 22, and the other end of the rotating plate 10 is fixedly connected to a connecting plate 9. Under the action of the rotating plate 10, the connecting plate 9 rotates around the axis of the rotating shaft 3. Since the connecting plate 9 is fixed to the horizontal plate 5, and the LED light panels 7 are fixed to the end of the horizontal plate 5, the horizontal plate 5 rotates with the LED light panels 7. The central column 4... An annular groove 6 is provided on the outer surface. Using the annular groove 6, the central column 4 can provide support for the horizontal plate 5 and the LED light panel 7, and at the same time assist the rotation of the horizontal plate 5. An arc-shaped telescopic rod 11 is fixed between the two connecting plates 9. When the connecting plate 9 rotates, the arc-shaped telescopic rod 11 extends and retracts. When the overall length of the arc-shaped telescopic rod 11 reaches its shortest, the first connecting plate 9 will push the second connecting plate 9 and the horizontal plate 5 and LED light panel 7 on the second connecting plate 9 through the arc-shaped telescopic rod 11. Since the last connecting plate 9 is fixedly connected to the central column 4 through the fixing rod 12, multiple LED light panels 7 can be concentrated together in this way to increase the brightness of the light source and thus meet the needs of the user.

[0019] Example 2: Please refer to Figure 1 and Figures 5-8 Based on Embodiment 1, a locking structure is also disclosed, the specific structure of which is as follows: a knob 13 is coaxially fixed at the top of the rotating shaft 3, a limiting ring 14 is fixed at the middle position of the first bracket 2, the rotating shaft 3 and the limiting ring 14 are slidably connected, a limiting block 15 is fixed on the rotating shaft 3, and two limiting grooves 16 are opened on the inner wall of the limiting ring 14, and the limiting grooves 16 match the limiting blocks 15; a lifting plate 17 is provided above the first bracket 2, the rotating shaft 3 and the lifting plate 17 are rotatably connected, a support ring 18 is fixed on the rotating shaft 3, and the support ring 18 matches the lifting plate 17; guide rods 19 are passed through both ends of the lifting plate 17, and the lifting plate 17 and the guide rods 19 are slidably connected, the bottom end of the guide rod 19 is fixedly connected to the first bracket 2, and the top end of the guide rod 19 is fixedly connected to the second bracket 20; a spring 21 is nested on the outside of the guide rod 19, one end of the spring 21 is fixedly connected to the lifting plate 17, and the other end is fixedly connected to the second bracket 20.

[0020] When it is necessary to rotate the shaft 3 via knob 13, first lift knob 13 upwards. Since the limiting groove 16 is opened on the inner wall of the limiting ring 14, and the limiting ring 14 is fixedly connected to the first bracket 2, the limiting block 15 is stuck in the limiting groove 16, which can restrict the rotation of the limiting block 15 and the shaft 3. After the limiting block 15 is disengaged from the limiting groove 16, the rotation restriction of the shaft 3 is released. At the same time, during the upward movement of the shaft 3 and knob 13, since the supporting ring 18 is fixed on the shaft 3, the supporting ring 18 cooperates with the lifting plate 17, and the lifting plate 17 rises synchronously with the shaft 3. Spring 21 is squeezed by lifting plate 17 and guided by guide rod 19. Lifting plate 17 can only move vertically. When rotating shaft 3 and knob 13 rise to the specified height, the bottom of rotating shaft 3 has not disengaged from rotating base 22 and can still rotate rotating base 22. Then rotate knob 13. When knob 13 is rotated to the specified angle, release knob 13. Under the rebound of spring 21, lifting plate 17 lowers with rotating shaft 3. Limiting block 15 on rotating shaft 3 is just locked into second limiting groove 16, thus re-limiting the rotation of rotating shaft 3. At this time, all LED light panels 7 are gathered together.

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.
