[0002] As living standards continue to improve, people are no longer satisfied with a single lighting method; the richness and dynamism of lighting colors are increasingly sought after. Different color temperatures can create different lighting environments and colors, thus giving people different psychological feelings. Through extensive comparative studies, low color temperatures evoke a warm, comfortable, and classic feeling, making them more suitable for emotional activities such as chatting; medium color temperatures evoke a refreshing, passionate, and fashionable feeling, suitable for reading and dining; and high color temperatures evoke a pure, fresh, bright, and serious feeling, more suitable for rational activities such as working and housework.

[0003] Traditional incandescent or energy-saving lamps have fixed color temperatures. Incandescent lamps typically have a fixed color temperature of around 2700K, while energy-saving lamps offer a wider range of color temperatures, such as 3000K, 4000K, and 6400K. However, these traditional light sources have fixed color temperatures that cannot be adjusted once manufactured. They can generally only be dimmed by adjusting brightness, and cannot flexibly adjust the color temperature and color as needed.

[0004] Existing dimming devices are not convenient for adjusting color temperature; they can generally only dim by adjusting brightness, and cannot flexibly adjust color temperature and color changes as needed. Utility Model Content

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this application. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0029] The dimming device of the intelligent lighting control system provided in this embodiment, such as Figures 1-6 As shown, it includes: a housing 1, with dimming film assemblies 5 connected to the upper and lower parts of the housing 1 respectively, a first outer end cover 2 and a second outer end cover 6 connected to the two ends of the housing 1 respectively, a first stepper motor 4 fixedly connected to the first outer end cover 2, a first inner end cover 10 fixedly connected to the output shaft of the first stepper motor 4, a rotating lampshade 9 fixedly connected to one end of the first inner end cover 10, three sets of lamp panels 12 with different color temperatures fixedly connected inside the rotating lampshade 9, the three sets of lamp panels 12 fixedly connected to form a triangular cylinder, lamp beads 13 installed on the lamp panels 12, three sets of metal contact pieces 14 fixedly connected to the first inner end cover 10, and a set of power supply contact pieces 15 provided on the inner side of the first outer end cover 2.

[0030] The semi-cylindrical reflector 8 on the outer side of the rotating lampshade 9 is made of high-reflectivity metal and can be rotated and adjusted by a second stepper motor 7. When the reflector rotates to different angles, its arc-shaped inner surface will directionally reflect the light emitted by the lamp panel 12, achieving precise control of the beam angle. The opening angle design of the reflector ensures smooth switching between diffused and focused light modes, and the second inner end cap 11 serves as a rotational support structure to ensure the stability of the reflector during rotation.

[0031] The second stepper motor 7 is linked to the second inner end cover 11 via a precision gear set and receives PWM control signals to achieve micro-step adjustment. The motor shaft coincides with the central axis of the reflector, ensuring no eccentricity or jitter during rotation. The built-in photoelectric encoder provides real-time feedback of position information, improving the angle positioning accuracy of the reflector, and works in conjunction with limit switches to prevent mechanical overload.

[0032] The power socket 3 uses a three-pin waterproof interface to transmit the safe 12V voltage after AC / DC conversion to the ring-shaped power supply contacts 15. The contacts are made of silver alloy to reduce contact resistance and maintain dynamic contact with the rotating metal contacts 14 through a spring-loaded pin structure.

[0033] The transparent waterproof shell is made of PC+PET composite material and formed into a fully sealed cavity through ultrasonic welding, achieving an IP67 protection rating. The shell is coated with an anti-glare AR coating on both sides, with a light transmittance of >92%, and is equipped with a silicone cushioning pad to prevent the dimming film assembly 5 from deforming under pressure.

[0034] The ITO conductive layer 51 serves as the main control electrode, changing the alignment of liquid crystal molecules through voltage regulation; the FZO conductive layer 55 serves as the auxiliary electrode, and its honeycomb conductive mesh can eliminate the voltage gradient difference of the ITO layer. Nanowire bridging technology is used between the two layers to ensure resistance stability even under bending conditions.

[0035] The columnar crystalline structure of the IZO conductive layer 52 improves lateral conductivity uniformity, while the zinc oxide doping of the GZO conductive layer 54 enhances longitudinal electron mobility. Both are combined using magnetron sputtering to form a nanoscale interpenetrating network, thereby improving the dimming response speed.

[0036] The AZO option of the additional conductive layer 53 is suitable for high-humidity environments, and its alumina-doped structure can suppress electrochemical corrosion; the PEDOT option achieves flexible stretching through conjugated polymer chains. This layer is deposited using a gradient deposition process to form an ohmic contact with the GZO layer, ensuring current stability under all operating conditions.

[0037] In summary, the dimming device of the intelligent lighting control system provided in this embodiment has the following advantages: the first step motor 4 drives the rotating lamp cover 9 to rotate, so that the three sets of lamp panels 12 with different color temperatures selectively face the lighting direction. The contact combination of the metal contact piece 14 and the power supply contact piece 15 realizes the power supply selection of different lamp panels 12. The three sets of lamp panels 12 are arranged in a triangular cylindrical shape, and the light emission ratio of each lamp panel 12 is controlled by the rotation angle.

[0038] The semi-cylindrical reflector 8 is driven to rotate by the second stepper motor 7, which can adjust the light reflection angle. The dimming film assembly 5 changes the light transmittance by adjusting the voltage of multiple conductive layers. The transparent waterproof shell protects the dimming film assembly 5 while maintaining light transmittance.

[0039] The power socket 3 transmits external power to the power supply contact 15. The metal contact 14 rotates with the lampshade and contacts different power supply contacts 15 to achieve circuit switching.

[0040] The ITO conductive layer 51 and the FZO conductive layer 55 form a basic conductive network. The IZO conductive layer 52 and the GZO conductive layer 54 enhance the conductivity uniformity. The additional conductive layer 53 provides supplementary conductivity. Different materials can be selected as needed.

[0041] Two stepper motors work together to control the lamp panel angle and reflector position respectively, while the dimming film assembly 5 independently controls the light transmittance. Through the combination of these three components, precise control of color temperature, brightness, and light angle is achieved.

[0042] In use, the first stepper motor 4 drives the rotating lamp cover 9 to rotate, so that the lamp panels 12 with different color temperatures face the lighting direction. At the same time, the metal contact piece 14 contacts the power supply contact piece 15 to switch the power supply, thereby realizing the color temperature adjustment. The second stepper motor 7 can adjust the angle of the semi-cylindrical reflector 8 to change the direction of light projection. The dimming film assembly 5 controls the light transmittance by adjusting the voltage of the conductive layer, thereby comprehensively realizing the intelligent adjustment of brightness, color temperature and light angle.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
