Description

Technical Field

[0001] The invention relates to the technical field of optical elements, in particular to a lighting device, a lighting system and a lighting roof building structure. Background Art

[0002] In modern architectural design and urban planning, effective use of natural lighting is crucial to improving indoor comfort and reducing energy consumption. With the continuous development of urban construction, the density of buildings is increasing, and parts of many buildings are in the shadow for a long time due to the obstruction of surrounding buildings, which seriously affects the natural lighting effect of these areas.

[0003] In order to solve the lighting problem in the shadow area of ​​the building, a lot of research has been conducted in the relevant technical field and a variety of lighting devices have been developed. For example, patent CN116413897A discloses a natural lighting device, which is mainly arranged near the building where the shadow area appears. It is intended to irradiate sunlight to the residents' side located in the shadow area of ​​the building. Its working principle is to receive the incident sunlight through the first reflecting part and reflect it, and the reflected light is then incident on the second reflecting part. The second reflecting part includes a second reflector, which forms a curvature with an axis intersecting the ground or an axis parallel to the ground as the center. The purpose is to allow the reflected sunlight to diffuse horizontally or avoid natural longitudinal diffusion, thereby illuminating the shaded area of ​​the building.

[0004] However, there are some problems in the actual application of such lighting devices. As the position of the sun changes throughout the day, the angle of sunlight continues to change, which causes the area of ​​sunlight reflected from the reflector below to the reflector above to change accordingly. When the area of ​​sunlight changes, part of the sunlight cannot be fully projected onto the reflector above, but is directly reflected into the air. This sunlight reflected into the air will cause serious interference to the normal flight movement of birds. Birds rely on natural light and visual cues to navigate during flight. The messy reflected sunlight will make birds lose their way and may even cause dangerous situations such as collisions during flight. In view of this, if such lighting devices are promoted and used on a large scale, it will have an immeasurable negative impact on the survival and migration of birds in the ecological environment, which greatly limits its wide application in actual scenarios.

[0005] There is an urgent need to innovate and improve the structure and reflection principle of daylighting devices to solve the above problems and ensure that the daylighting devices can not only efficiently utilize solar energy to meet the lighting needs of buildings, but also minimize the adverse impact on the ecological environment.
