[0030] The role is: sunlight transmits through the heat insulation lighting window 3 and is refracted into the room through the reflecting plate 6, can uniformly diffuse the natural light to every corner of the room, effectively introduces the natural light, improves the indoor lighting quality, also reduces the eye fatigue, improves the visual comfort; the photovoltaic panel 2 converts solar energy into electric energy, provides clean energy for the building, reduces the dependence on the traditional power grid, at the same time, the adjusting plate 4 adjusts the ventilation channel according to the indoor and outdoor temperature, realizes the natural ventilation by using the thermal pressure difference, enhances the indoor and outdoor air exchange efficiency, improves the air quality, further reduces the indoor refrigeration and heating energy consumption;
[0031] As Figure 1 When the indoor temperature is higher than the outdoor temperature in summer, the adjusting plate 4 is rotated to close between the reflecting plate 6, the indoor hot air is cooled outward through the channel between the supporting inclined plate 1 and the reflecting plate 6 and the opening between the supporting inclined plate 1 and the heat insulation lighting window 3 in turn; as Figure 2 When the indoor temperature is lower in winter, the adjusting plate 4 is rotated to close between the supporting inclined plate 1, at the same time, on the basis of the waste heat utilization of the photovoltaic panel 2, the indoor hot air is circulated, the heat loss is reduced.
[0032] The rectangular openings disclosed in the embodiment are arranged in an array on the roof 0, so that the indoor light and temperature ventilation are more uniform.
[0033] The heat insulation lighting window 3 disclosed in the embodiment is a double-layer glass heat insulation lighting window and the interlayer is filled with a heat insulation material, which not only effectively introduces the natural light and reduces the indoor lighting energy consumption, but also reduces the heat transfer through the heat insulation layer and optimizes the indoor thermal environment.
[0034] The service life of the photovoltaic panel 2 and the heat insulation lighting window 3 of the embodiment is long, the maintenance and replacement frequency of the traditional lighting system and air conditioning equipment are reduced, and the maintenance cost is reduced.

By reducing the dependence on traditional energy, the carbon emissions of the building are reduced, and the impact on the environment is reduced. And unlike the direct lighting way of the traditional skylight, the skylight of the embodiment can diffuse the light through its unique diffuse lighting design, so that the indoor light is more uniform, avoiding the problem of local over-brightness or over-darkness, not only improving the indoor lighting efficiency, but also reducing the demand for artificial lighting through natural lighting, reducing energy consumption, uniformly illuminating the indoor environment, so that the museum and exhibition hall can better display the art and exhibits, and at the same time, create a comfortable and bright environment for visitors; in appearance, the modern and technological sense of the zigzag skylight is in harmony with the architectural style of the museum and exhibition hall, improving the overall aesthetics of the building.
[0035] In this embodiment, the adjustment plate 4 and the heat-insulating light-transmitting window 3 are hinged together by a power mechanism 5. The power mechanism 5 includes a hinge shaft that hinges the adjustment plate 4 and the heat-insulating light-transmitting window 3, and a rotary motor located at the end of the hinge shaft. The rotary motor rotates to drive the hinge shaft to rotate, and in turn, the adjustment plate 4 rotates.
[0036] In this embodiment, an extension plate 1-1 is horizontally connected to the upper edge of the supporting inclined plate 1 towards the south. The extension plate 1-1 covers the heat-insulating and light-transmitting window 3 in the vertical direction to provide rain protection during the rainy season. A first limiting groove 1-10 is provided at the connection between the extension plate 1-1 and the upper edge of the supporting inclined plate 1 to limit the free edge of the adjusting plate 4 and limit the rotation of the adjusting plate 4.
[0037] In this embodiment, the lower edge of the reflector 6 is flush with the upper surface of the roof 0. The lower edge of the reflector 6 is vertically connected to the guide plate 6-1, and the lower edge of the guide plate 6-1 is not lower than the lower surface of the roof 0, which serves to guide the airflow. The upper edge of the reflector 6 is provided with a second limiting groove 6-2 to limit the free edge of the adjustment plate 4, so as to limit the rotation of the adjustment plate 4.
[0038] The electrical diagram of the accessories in this embodiment is as follows: Figure 5 As shown, a temperature sensor determines whether ventilation is needed. Meanwhile, the solar energy received by the photovoltaic panels is converted into electrical energy by an inverter. This electrical energy can be used for power supply, heating, and charging of electric vehicles inside the building through a distribution box. It can also be equipped with anti-backflow facilities to supply power to the low-voltage power grid and deliver electricity to thousands of households.
[0039] In this embodiment, indoor and outdoor temperature and light intensity can be collected by temperature and light sensors. A control system connected to the temperature and light sensors via a rotary motor can also be configured to achieve automated control. During the hot summer months, the indoor and outdoor temperature difference is large, and the light intensity is strong. When a certain threshold is reached, the microprocessor controls the opening of the regulating plate 4. This action causes the waste heat generated by the original photovoltaic panel and the warmer indoor air to rise and be exhausted through the vents, while the cool air sinks, utilizing the thermal pressure difference to achieve natural ventilation, thereby effectively reducing the indoor temperature. In winter, when the temperature sensor detects that the indoor temperature is higher than the outdoor temperature, the microprocessor controls the electric actuator to adjust the regulating plate 4. The warm indoor air passes through the inner vents. At this time, the main function of the ventilation system is to utilize indoor heat to achieve thermal pressure ventilation while reducing heat loss. The power mechanism 5 starts operating.
