Problems solved by technology

With the passive natural lighting method, the lighting quality will be limited by the location, area, size, orientation, etc. of the lighting opening
For buildings with large plane depth and high height, and the area of ​​the daylight opening should not be too large, passive daylighting methods often cannot meet their daylighting needs

Embodiment Construction

[0041] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0042] This embodiment is an exhibition building 8 in Shanghai, which has a large depth, small side windows, and high floors. The leisure area and green vegetation located in the middle of the building cannot get enough lighting through the atrium skylight, and the active natural light guide device of the present invention can enhance lighting. The roof 7 of the building 8 is provided with a rear row of heliostats 1 and a front row of heliostats 2, and a reflector 3 is arranged above the north side of the rear row of heliostats 1 and the front row of heliostats 2. Directly below the 2 is provided with a skylight 4 and a diffuser 5. The diffuser plate 5 is combined with the skylight 4 through a bracket 9 . The height of the heliostats 1 and 2 is between the reflector 3 and the skylight 4 . The rear row of heliostats 1 and the front row of...

Abstract

The invention belongs to a construction technology, in particular to an active type natural light guide method and a device. The traditional building adopts a passive type natural lighting method, and the lighting quality is restricted by the position, the area, the size, the orientation and the like of a daylight opening. The active type natural light guide method guides sunlight into a building by the modes of collection, reflection, transmission and scattering. Two heliostats (1) and (2) which are arranged at the front and the back of a roof (7) of a building and can track the illumination angle of the sun collect the sunlight actively, and the sunlight is focused and irradiated to a reflecting mirror (3); and light rays are irradiated to a skylight (4) by the reflecting mirror (3), pass through a diffusing panel (5), are scattered and enter an atrium (6) of the building. The invention has the advantages of prolonging the sunshine time in the building, enhancing the lighting illumination in the building, enhancing the comfort level of a luminous environment in the building and providing conditions for the growth of green plants in the areas of the atrium and a patio in the building.

Description

technical field [0001] The invention belongs to building technology, in particular to an active natural light guiding method and device suitable for building atriums or patios. Background technique [0002] Building natural lighting is an important part of sustainable design of buildings. The introduction of natural lighting into buildings can not only reduce the energy consumption of architectural lighting, but also has advantages that are difficult to achieve with artificial lighting: it can make people feel the subtle changes formed by the sun and the sky, reduce seasonal affective disorder and chronic fatigue; The building is rich in light and shadow changes, making the space more interesting and humanized. [0003] At present, passive natural lighting methods are usually used in buildings, that is, lighting is carried out by using lighting openings, such as side window lighting, skylight lighting, and lighting cover lighting. With the passive natural lighting method, ...
