Description

Technical Field

[0001] The present invention relates to the technical field of building lighting, and in particular to an intelligent light-control building energy-saving lighting structure and method. Background Art

[0002] A skylight roof is a building structure design that uses transparent or translucent materials to cover the roof to bring in natural light and reduce dependence on artificial lighting. This design not only saves energy but also creates a bright and comfortable indoor environment. Skylight roofs are usually combined with the exterior design of the building to ensure its structural stability and aesthetics, while also taking into account functional requirements such as insulation and waterproofing. When designing, the inclination angle of the roof must also be considered to maximize the use of natural light.

[0003] Traditional building lighting systems mostly use fixed light-transmitting structures or manually adjustable shading facilities, which cannot dynamically adjust the transmittance according to the real-time light intensity. For example, conventional skylights can easily cause glare or overheating in the room under strong light conditions, and need to rely on artificial lighting to supplement, resulting in energy waste. Statistics show that the air-conditioning energy consumption of such systems in the summer increases by about 25% to 40% due to direct sunlight. In addition, existing shading devices (such as fixed blinds or simple mechanical roller blinds) can only achieve limited angle adjustment, cannot accurately match the needs of light changes, and the adjustment response speed generally exceeds 2 seconds, which makes it difficult to meet the dynamic needs of real-time environmental changes.

[0004] In existing technologies, lighting, shading, and air-conditioning systems are mostly independently operated units, lacking a coordinated control mechanism. For example, shading facilities cannot adjust the light transmittance according to the temperature difference between indoor and outdoor, resulting in the air-conditioning system requiring additional load to compensate for temperature fluctuations. Studies have shown that this type of independent operation mode reduces the overall energy efficiency of the building by 15% to 20%. In addition, traditional control algorithms (such as linear PID) have difficulty coping with complex weather conditions (such as sudden cloudy and sunny periods, seasonal changes), and often experience adjustment lag or overshoot problems. The indoor illumination fluctuation range exceeds ±100 Lux, affecting visual comfort. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides an energy-saving building lighting structure and method with intelligent light control, which solves the problems of being unable to dynamically adjust the transmittance according to the real-time light intensity, and the lighting, shading and air-conditioning systems being mostly independently operated units and lacking a coordinated control mechanism.
