Sunlight conduction device for underlying houses

Abstract

The invention discloses a sunlight conduction device for underlying houses. The sunlight conduction device for the underlying houses comprises a parabolic cylinder curved condenser lens and a light adjusting structure which are fixedly installed and share the same optical shaft, and the center shafts of the parabolic cylinder curved condenser lens and the light adjusting structure are parallel and located in the same vertical plane and have the same focus. The parabolic cylinder curved condenser lens is installed facing the sun, and the reflective hook surface directions of the light adjusting structure and the parabolic cylinder curved condenser lens are opposite; the included angle between a plane formed by a first reflective sideline of the light adjusting structure and a third reflective sideline of the parabolic cylinder curved condenser lens and the horizontal plane is 55-60 degrees, the included angel between a plane formed by a second reflective sideline of the light adjusting structure and a fourth reflective sideline of the parabolic cylinder curved condenser lens and the horizontal plane is 112-118 degrees, and the plane where the first reflective sideline and the second reflective sideline of the light adjusting structure are located and the plane where the third reflective sideline and the fourth reflective sideline of the parabolic cylinder curved condenser lens are parallel; and the light adjusting structure is fixedly installed on the window brow, and the parabolic cylinder curved condenser lens is installed below the light adjusting structure.

Description

technical field [0001] The present application relates to a sunlight conduction device, in particular to a sunlight conduction device for a ground floor building. Background technique [0002] In places such as Zhejiang in the south, the angle of sunlight in winter is about 30°. Factors such as the small distance between old-style residential buildings and the good greening and shading effect in the community lead to poor lighting effects in the ground floor of old-style residential buildings, and the indoor effective lighting area is small. It is a one-story or one-and-a-half-story house, and the effective sunshine time is only 1 to 2 hours. There are many sunlight conducting devices in the prior art, for example, an energy-saving and environment-friendly architectural lighting decorative panel disclosed in patent 200710052425.7 and a solar indoor lighting optical fiber conducting device and its working method disclosed in patent 201210458926.6; the above two patents both d...

Problems solved by technology

However, the technical solutions of these two patents are not very applicable to old-fashioned houses: firstly, the renovation costs of the above-mentioned patents are high, and the old-fashioned houses themselves are suitable for living for a short period of time, so the average cost of use per year of residence after renovation is high ; Secondly, the old-fashioned residential area is small, and the lighting facilities take up too much space, which will reduce the living comfort of the house.
