Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a spotlight module. Background Technology

[0002] The lighting environment is an important indicator for evaluating the architectural design level of museums and art galleries, and it also has a significant impact on visual aesthetics. As an artificial light source, artificial light complements natural light and becomes a major component of the lighting environment in places such as art galleries and museums, playing an important connecting role between people and objects in art galleries and museums.

[0003] Currently, natural light, halogen lamps, fluorescent lamps, and incandescent lamps are the commonly used traditional light sources in museums and art galleries. Natural light is energy-saving and environmentally friendly, but it often emits ultraviolet and infrared radiation, causing photochemical hazards, and has significant drawbacks such as heat generation and unstable light source. Like natural light, fluorescent lamps, incandescent lamps, and halogen lamps also emit ultraviolet or infrared radiation, and are prone to heat generation and high energy consumption. Ultraviolet radiation has a short wavelength and high photon energy, making it easily absorbed by objects and converted into internal energy. This will further trigger photochemical reactions, causing the organic carbon chains of exhibit materials to break, resulting in embrittlement and fading of the exhibit surface, ultimately causing serious damage to the exhibit. The blue light hazard produced by ordinary LED products on the market has also raised controversy. Blue light not only easily damages exhibits, but its harm to human eyes should not be ignored.

[0004] With the introduction of the concept of low-carbon museums and art galleries, modern society has put forward a series of new requirements for the lighting systems of museums and art galleries, such as energy conservation, environmental protection and sustainability, zero ultraviolet and infrared radiation, no photochemical hazards, and green, healthy and eye-protecting features.

[0005] Proper lighting helps maintain the necessary environmental conditions in the exhibition area. To prevent inconvenience or light damage caused by excessive darkness or improper lighting, museums and art galleries need to keep the lights on for extended periods during the designated viewing time, even when the exhibits are unoccupied. However, improper selection or use of the lighting fixtures used for such extended periods can easily cause light damage to the exhibits. To meet the different lighting needs of museums and art galleries when the exhibition area is unoccupied or occupied, and to satisfy the different requirements for the illumination range of the exhibits, using existing lighting fixtures would require installing multiple fixtures, which would be relatively costly.

[0006] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0040] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and drawings of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0041] like Figures 1-4 As shown, this embodiment provides a spotlight module, including a mounting plate 10 and a controller fixedly mounted on the mounting plate 10. The controller is a conventional PLC controller, which has the conventional function of analyzing and comparing input signals to output corresponding control signals.

[0042] Mounting plate 10 is detachably connected to rotating disk 20 via a first fixing component. Mounting plate 10 is also detachably connected to infrared detector 21 via a second fixing component. Infrared detector 21 is electrically connected to controller. Rotating disk 20 is fixed to docking ring 22 via a first fixing shaft. Drilling ring 22 is spirally connected to spotlight assembly. Spotlight assembly includes outer cylinder 23, lens 24, heat sink 25, lamp plate 26, and control main board 27. Specifically, the inner side wall of docking ring 22 is provided with an internal thread section, and the outer peripheral wall of outer cylinder 23 is provided with an external thread section that mates with the internal thread. The internal thread section and the external thread section are threadedly connected, and the threaded connection between docking ring 22 and spotlight assembly is achieved through the mating of the internal thread section and the external thread section.

[0043] The outer cylinder 23 has an internal cavity. The lens 24, lamp board 26, control main board 27, and heat sink 25 are sequentially installed in the cavity along the axial direction of the outer cylinder 23. It should be noted that the installation method of the lens 24, lamp board 26, control main board 27, and heat sink 25 with the outer cylinder 23 is not the content to be protected by this utility model, and this installation method and specific structure are existing technologies, which will not be described in detail here. The control main board 27 is electrically connected to the controller. The lens 24 is away from the mounting plate 10 relative to the lamp board 26. The side of the lamp board 26 away from the control main board 27 is provided with a first LED and a silicon-based yellow LED. The first LED is non-silicon-based. A yellow LED light bead is slidably fitted outside the outer cylinder 23 with a second reflector 47 arranged coaxially with and in a cylindrical shape. One end of the outer cylinder 23, away from the mounting plate 10, is located inside the second reflector 47, and the other end of the outer cylinder 23 is also located inside the second reflector. A first reflector 28, coaxially arranged with the second reflector 47, is slidably fitted outside the second reflector 47. The first reflector 28 includes a cylindrical section 29 and a conical diffuser section 30. The small end of the conical diffuser section 30 is connected to and communicates with the cylindrical section 29. The conical diffuser section 30 is away from the mounting plate 10 relative to the cylindrical section 29. The end of the second reflector 47 closest to the mounting plate 10 is located inside the cylindrical section 29. The other end of 47 is located outside the cylindrical section 29. An adjustment component for adjusting the relative positions of the second reflector 47 and the first reflector 28 is also provided inside the cylindrical section 29. Before use, the spotlight module provided in this embodiment is installed in a museum or art gallery. Preferably, the color temperature of the silicon-based yellow LED beads is in the range of 1800K-2200K, and the color rendering index of the silicon-based yellow LED beads is in the range of 70-100. During use, an infrared detector 21 detects whether there are people in the exhibition area. When someone is detected in the exhibition area, the controller controls the main board 27, which in turn controls the first LED bead to light up and the silicon-based yellow LED bead to turn off. Simultaneously, the controller retracts the first reflector 28 relative to the second reflector 47, allowing the light emitted by the first LED to illuminate the exhibition area through the second reflector 47. When no one is detected in the exhibition area, the control board 27 turns off the first LED and turns on the silicon-based yellow LED. At the same time, the controller retracts the second reflector 47 relative to the first reflector 28, allowing the light emitted by the silicon-based yellow LED to diffuse into the surrounding space through the conical diffuser section 30. This allows the spotlight assembly to switch between ordinary lighting LED mode and silicon-based yellow LED mode, meeting the needs of different scenarios. It eliminates the need for multiple light fixtures and has a relatively low cost.

The outer peripheral wall of the outer cylinder 23 has a third through hole for the belt 38 to pass through. In this embodiment, there are two adjustment components. The two adjustment components are symmetrically distributed with the axis of the outer cylinder 23 as the center. When it is necessary to adjust the relative position of the second reflector 47 and the first reflector 28, the controller controls the motor 32 to start. The start of the motor 32 drives the drive wheel to rotate. The rotation of the drive wheel drives the driven wheel to rotate. The rotation of the driven wheel drives the rotating gear 37, which is integrally connected to the driven wheel, to rotate, thereby realizing the adjustment of the relative position of the second reflector 47 and the first reflector 28.

[0045] A limiting groove is provided on the outer peripheral wall of the outer cylinder 23. The limiting groove is arranged along the axial direction of the outer cylinder 23.
