[0002] LED lights are lighting devices that use light-emitting diodes as the light source. They have advantages such as high efficiency, energy saving, long life and environmental protection. They are a replacement for traditional incandescent lamps and fluorescent lamps. Traditional dual-color temperature LED lights usually use a single LED light source module. The color of light is changed by switching different colored LED beads or adjusting the working current of the LED. Therefore, a dual-color temperature LED light that can adjust the light and color temperature is needed.

[0003] A dimmable and color-temperature-adjustable dual-color-temperature LED luminaire is an intelligent LED luminaire. It integrates LED chips with both cool white and warm white light color temperatures. Through an intelligent control system, users can independently and continuously adjust the brightness and color temperature of the luminaire, creating an ideal lighting environment suitable for different scenarios and moods. In terms of heat dissipation, traditional LED luminaire designs often rely on natural heat dissipation from the luminaire casing or simple heat sinks. In high-power applications, this may be insufficient to quickly dissipate heat, easily leading to overheating and affecting the lifespan and performance of the LED light source.

[0011] As a further description of the above technical solution: A spring is fixedly connected to the lower surface of the lamp body rear cover, and the lower surface of the spring abuts against the lower surface of the positioning strip.

[0012] Through the above technical solution: the back cover of the lamp body supports the spring sheet, and the heat dissipation holes opened inside the spring sheet abut against the channel of the positioning strip, which can play a role in assisting heat dissipation.

[0013] As a further description of the above technical solution: The lamp body rear cover is fixedly connected to a fixing component inside, and a lifting arm is engaged inside the lamp body rear cover. A rotating shaft is rotatably connected inside the lifting arm. The outer wall of the rotating shaft is rotatably connected to the fixing component and the lamp body rear cover. A track head is threadedly connected to the outer wall of the lifting arm.

[0014] The above technical solution involves placing the boom inside the rear cover of the lamp body, but slightly off-center. The lamp body can be connected to the track head by rotating the boom and the shaft. The angle of the lamp body can be adjusted by rotating the shaft.

By maintaining a constant LED drive current and only adjusting the on / off time ratio, the luminaire is ensured to always work at the optimal luminous efficacy point, avoiding spectral drift and efficiency reduction caused by current changes in analog dimming. This ensures high stability of the output light color. At the same time, because the LED beads always work at the rated current and the heat generation is effectively controlled, their light decay rate is significantly slowed down, and the lifespan of the luminaire is significantly extended. Ultimately, while providing a rich and smooth light color experience, it achieves a comprehensive set of excellent characteristics including high efficiency, stability, and long lifespan.

[0025] 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.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An embodiment of this utility model provides: a dual-color temperature LED lamp with adjustable light and color temperature, including a lamp body 1, a fixing ring 2 internally threaded to the lamp body 1, a heat sink 8 snapped onto the inner wall of the lamp body 1, an abutment groove 12 formed on the outer wall of the heat sink 8, a lens body 3 abutting the lower surface of the fixing ring 2, a lens fixing sleeve 4 sleeved on the outer wall of the lens body 3, a fixing plate 5 fixedly connected to the lower surface of the lens fixing sleeve 4, a dual-color temperature LED light source board 6 disposed inside the fixing plate 5, the lower surface of the fixing plate 5 abutting the inner bottom wall of the heat sink 8, a screw 7 internally threaded to the fixing plate 5, a screw 7 externally threaded to the inside of the heat sink 8, a power supply box 9 slidably connected inside the heat sink 8, a driver 10 fixedly connected inside the power supply box 9, a power supply box cover 11 fixedly connected inside the power supply box 9, and a limit component disposed inside the lamp body 1; Specifically, the lamp body 1 and the fixing ring 2 are connected by threads. The fixing ring 2 is fixed above the lamp body 1 and can limit the position of the lens body 3. The lens fixing sleeve 4 supports the lens body 3, keeps the lens in the correct position, and protects the lens body 3. The lens body 3 is used to focus or diffuse light and improve light distribution. The upper surface of the lens fixing sleeve 4 is provided with protrusions, and the upper surface of the fixing plate 5 is provided with grooves. By engaging the protrusions with the grooves, the fixing plate 5 can be fixed to the lower surface of the lens fixing sleeve 4. The lower side of the lens fixing sleeve 4 has a square groove, which prevents the fixing plate 5 from being squeezed and damaged when placed inside the heat sink 8. The power supply box 9 has elongated cylindrical slots inside, and the heat sink 8 has holes inside to accommodate these elongated cylindrical slots. After the power supply box 9 is placed inside the heat sink 8, the screw 7 is passed through the fixing plate 5 through the heat sink 8 and rotated. The driver 10 is fixed inside the power supply box 9, thereby fixing the fixing plate 5 and the power supply box 9 inside the heat sink 8. The driver 10 has holes inside, and the upper side of the power supply box cover 11 is provided with a locking block. The locking block can fix the power supply box cover 11 to the power supply box 9. At the same time, the power supply box cover 11 supports the driver 10. The driver 10 is a 24V input dimming and color temperature adjustment driver, which can realize color temperature control in LED application scenarios with constant voltage input power supply. After the power supply box cover 11 is placed on the inner bottom wall of the driver 10, after the driver 10 is fixed to the power supply box cover 11, the elongated cylindrical slot of the power supply box 9 can limit the offset of the driver 10, ensuring the stability of the driver 10. By integrating the driver 10 inside the lamp body 1, the convenience can be improved and the complexity of the system can be reduced. The heat sink 8 installed inside the lamp body 1 can quickly dissipate heat and improve the service life and performance of the LED light source.

[0027] Reference Figure 1 , Figure 2 and Figure 6 The limiting component includes a positioning strip 13, the outer wall of which is fixedly connected to the inner wall of the lamp body 1, the outer wall of which abuts against the inside of the abutment groove 12, and a fixing block 14 is fixedly connected to the inner wall of the lamp body 1. Specifically, the lamp body 1 can support and limit the displacement of the heat sink 8 through the internally fixed positioning strip 13. When the heat sink 8 is inserted into the lamp body 1 from top to bottom, the positioning strip 13 will abut against the inner wall of the abutment groove 12 of the heat sink 8, thereby supporting the heat sink 8. By supporting the heat sink 8, the heat sink 8 can support the components installed inside the lamp body 1. The lamp body 1 has a fixing function on the fixing block 14, which is also used for support and limiting displacement. Through the contact between the heat sink 8 and the positioning strip 13, the heat dissipation path can be expanded, allowing heat to be transferred from the heat sink 8 to the outside of the lamp body 1 through the positioning strip 13, effectively improving the heat dissipation effect of the lamp body 1.

[0028] Reference Figure 2 , Figure 6 and Figure 7 The outer wall of the fixing block 14 is snapped with the lamp body rear cover 15, and the outer wall of the lamp body rear cover 15 is attached to the inner wall of the lamp body body 1; the lower surface of the lamp body rear cover 15 is fixedly connected with a spring piece 16, and the lower surface of the spring piece 16 abuts against the lower surface of the positioning strip 13. Specifically, the outer wall of the lamp body rear cover 15 has a sliding groove. The entrance to the sliding groove has a recess on the outer wall of the lamp body rear cover 15 to facilitate the insertion of the fixing block 14. The other end of the sliding groove matches the shape of the fixing block 14, facilitating engagement. After the fixing block 14 is inserted into the lamp body rear cover 15, rotating the lamp body rear cover 15 causes the fixing block 14 to engage with the other end of the sliding groove, thus fixing the lamp body rear cover 15 inside the lamp body 1. This rotation method also makes the installation and removal of the lamp body rear cover 15 more convenient. The spring clip 16 is fixed to the lamp body. After the lamp body rear cover 15 is installed inside the lamp body body 1, the spring piece 16 will abut against the lower surface of the positioning strip 13. When the spring piece 16 contacts the positioning strip 13, it will be squeezed downward, which will generate a rebound force. The spring piece 16 achieves elastic limiting, reducing the possibility of the fixing block 14 disengaging from the slide groove, thereby making the lamp body rear cover 15 more stably fixed inside the lamp body body 1. The spring piece 16 has heat dissipation holes inside, and the positioning strip 13 has channels inside. The connection between the heat dissipation holes and the channels can play a role in assisting heat dissipation.

[0029] Reference Figure 7 The lamp body rear cover 15 is fixedly connected to a fastener 17, the lamp body rear cover 15 is engaged with a hanger 18, the hanger 18 is rotatably connected to a rotating shaft 19, the outer wall of the rotating shaft 19 is rotatably connected to the fastener 17 and the lamp body rear cover 15, and the outer wall of the hanger 18 is threadedly connected to a track head 20. Specifically, the boom 18 has an L-shaped design. The lamp body rear cover 15 supports and fixes the fixing member 17. The fixing member 17 is fixed inside the lamp body rear cover 15 by bolts. The fixing member 17 has a limit offset function for the rotating shaft 19 to prevent the rotating shaft 19 from shifting. The lamp body rear cover 15 supports the rotating shaft 19, and the rotating shaft 19 supports the boom 18. The lamp body rear cover 15 also has a protective function for the boom 18. At the same time, the lamp body rear cover 15 can prevent the boom 18 from colliding with the lamp body 1. The internal components are connected by an L-shaped boom 18, with one end rotatably connected to the shaft 19 inside the lamp body rear cover 15. This allows the lamp body 1 to be rotatably connected to the boom 18, enabling angle adjustment. The boom 18 also contains a pin and a starting gear. When the lamp needs to be connected to a power source, the gear can be rotated to expose the pin on the track head 20, making it easy to insert into the power supply socket. Both the track head 20 and the boom 18 contain wires, which can supply power to the lamp body through the pin.

[0030] Reference Figure 1 and Figure 8 The lamp body 1 is equipped with a user interaction control module. The output signal of the user interaction control module is connected to the input of the communication interface module and the instruction parsing module. The output signal of the communication interface module is connected to the input of the instruction parsing module. The output signal of the instruction parsing module is connected to the input of the core control module. Specifically, the user interaction control module, as the main input interface of the system, consists of the microcontroller's general-purpose input / output pins, analog-to-digital converter pins, and corresponding local input hardware such as buttons, knobs, and touch sensors. It is used to collect the user's physical operations and convert them into raw electrical signals, which are then transmitted in parallel to subsequent modules for processing. The output signal of the user interaction control module is connected to the input of the communication interface module and the instruction parsing module, which transmits raw electrical signals representing intentions such as switching and dimming in parallel to subsequent modules for processing. The communication interface module connects to an external independent Wi-Fi or Bluetooth chip via a serial bus by driving a serial communication peripheral. It is responsible for receiving and initially verifying wireless data frames from mobile apps, cloud platforms, or voice assistants, and restoring them to raw data frames. The output signal of the instruction parsing module is connected to the input of the core control module, which can uniformly parse and convert raw instructions from different channels and formats into standardized control commands that can be recognized and executed within the system, and send them to the core control module as the basis for its decision-making and execution.

[0031] Reference Figure 3 and Figure 8The output signal of the core control module is connected to the input of the lighting mixing module. The bidirectional signal of the core control module is connected to the storage management module. The output signal of the lighting mixing module is connected to the input of the PWM drive module. The output of the PWM drive module is connected to the input of the driver 10. The output of the driver 10 is electrically connected to the input of the dual-color temperature LED light source board 6. Specifically, after receiving standardized instructions, the core control module connects its output signal to the input of the lighting mixing module, converting the user-defined abstract light and color intentions into specific execution strategies. The core control module and the storage management module are bidirectionally connected; on one hand, the core control module writes current system status data such as brightness, color temperature, and on / off status to storage; on the other hand, it reads historical states from power-on initialization, enabling power-off memory functionality for the lighting fixtures. The output signal of the lighting mixing module is connected to the input of the PWM driver module. The lighting mixing module contains a full color gamut mapping table that calculates the precise brightness percentage required for both cool and warm LEDs, converting the light and color strategy into hardware execution parameters. The PWM driver module generates two independent signals by configuring the timer's compare register. The PWM control signal is connected to the input of the driver 10. The PWM control signal transmits dimming information. The PWM driver module can generate a PWM signal with a duty cycle that changes steplessly from 0% to 100%, thereby achieving infinitely precise control over the brightness of the two LEDs. This allows the color temperature to be adjusted steplessly and smoothly across the entire spectrum without any level limitations. The output of the driver 10 is electrically connected to the input of the dual-color temperature LED light source board 6. After receiving the PWM signal, the driver 10 can always provide a stable and precise rated current to the LEDs. By adjusting the duty cycle of the output current, the luminous intensity of each string of LEDs can be directly controlled, thereby achieving a light mixing effect. This allows the LED beads to continuously work at their optimal efficiency and reduces heat generation.

[0032] Working principle: When the lamp is needed, the driver 10 is placed inside the power supply box cover 11. The driver 10 allows for color temperature control in LED applications with constant voltage input. The power supply box cover 11 is then fixed to the power supply box body 9 via a snap-fit ​​connection. The fixed assembly is placed inside the lower side of the heat sink 8. The fixing plate 5 is then placed inside the upper side of the heat sink 8. The screw 7 is then passed through the fixing plate 5 and rotated, securing the fixing plate 5 and the power supply box body 9 through the threaded action, thus installing them inside the heat sink 8. The lens fixing sleeve 4 is then fixed to the fixing plate 5 via a snap-fit ​​connection. Finally, the lens body 3 is placed inside the lens fixing sleeve 4. Then, the heat sink 8 is placed inside the lamp body 1 from top to bottom. The positioning strip 13 on the inner wall of the lamp body 1 abuts against the abutment groove 12 on the outer wall of the heat sink 8, which provides a fixed support for the heat sink 8. The contact between the heat sink 8 and the positioning strip 13 can expand the heat dissipation path, allowing heat to be transferred from the heat sink 8 to the outside of the lamp body 1 through the positioning strip 13, effectively improving the heat dissipation effect of the lamp body 1. Then, the fixing ring 2 is fixed to the top of the lamp body 1 by the thread, which serves as a limit offset. The boom 18 and the track head 20 are fixed by the threaded connection. The boom 18 can be rotated by the rotating shaft 19, which in turn can drive the track head 20 to rotate, thereby realizing angle adjustment. The user interaction control module and communication interface module, acting as the system perception layer, collect two heterogeneous inputs in parallel: local physical operations and remote wireless commands. The command parsing module, as the central hub, translates, verifies, and converts these raw inputs into standardized internal commands. The core control module receives the commands, makes decisions, updates the system target state, and uses the storage management module to store key data in non-volatile memory for power-off memory. The decision results are sent to the lighting mixing module, which queries a preset algorithm curve to calculate the abstract brightness and color temperature targets into specific cool and warm light brightness ratios. The PWM drive module then generates two PWM signals with corresponding duty cycles, which are output to driver 10, which converts them into... The pulsed current precisely drives the dual-color temperature LED light source board 6, thereby avoiding the defects of traditional dimming while mixing any light color effect specified by the user. This device not only improves installation flexibility and makes it more convenient to use, but also expands the heat dissipation area by setting a heat sink 8 inside the lamp body 1, improving the heat dissipation effect and effectively extending the life and performance of the LED light source. The integrated driver 10 inside the lamp body 1 reduces the complexity of the system. At the same time, through the precise algorithm of the light mixing module and the high-frequency pulse control of the PWM drive module, stepless smooth transition can be achieved in the full color temperature range, effectively eliminating color temperature jumps and adjustment range limitations, and keeping the LED driving current constant and only adjusting the on and off time ratio, thus extending the life of the lamp.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
