Problems solved by technology

However, the focal length of the light-gathering device results in a huge volume of the known solar conversion device. The large-volume solar conversion device not only requires higher production and material costs, is difficult to precisely move and control the sun tracking, but also requires a large area of ​​the device. The light pipes currently occupying the mainstream of the market are low in efficiency, poor in lighting uniformity, and may cause damage to the original building structure during installation, which is not conducive to promotion and popularization

Embodiment 1

[0032] Example 1: An attached figure 1 As shown, the present embodiment provides a natural light homogenization lighting device based on a double lens, including the ideal lens in the form of two array before and after, respectively, a negative lens array and a positive lens array, and the negative lens array is used to collect outdoor natural light. And via an intermediate medium air layer to a positive lens array; a positive lens array is used to deflect the incident natural light after refraction to the indoor space. The negative lens array and the positive lens array include N unit structures, and one or one corresponds to Nature than or equal to 1.

[0033] More specifically: the lens surface of the negative lens array faces the natural light incident direction, the lens mirror method and the incident natural light angle are acute angle, and the natural light incident in the outer angle of the house can be divergent into the housing in the house. figure 1 Indicated.

[0034] ...

Embodiment 2

[0040] Example 2: Based on the apparatus of Example 1, a natural light homogenization method based on a double lens negative combination is designed, including:

[0041] Outdoor natural light is collected by the negative lens and is conducted to the positive lens array via an intermediate medium air layer;

[0042] The positive lens array deflects the natural light refraction to the indoor space.

Embodiment 3

[0043] Example 3: An attached image 3 As shown, the present embodiment provides a natural shaded lighting device based on a double lens, including a lens in the form of two array before and after, a negative lens array and a positive lens array, and a negative lens array is used to collect outdoor natural light. The air lens array is conducted via an intermediate medium air layer; the positive lens array is used to deflect the incident natural light after refraction to the indoor space. The negative lens array and the positive lens array include N unit structures, and one or one corresponds to Nature than or equal to 1.

[0044]More specifically: the lens surface of the negative lens array faces the natural light incident direction, the lens mirror method and the incident natural light angle are acute angle, and the natural light incident in the outer angle of the house can be divergent into the housing in the house. image 3 Indicated.

Abstract

The invention discloses a natural light homogenization lighting device and method based on double-lens negative and positive combination. The natural light homogenization lighting device and method can be used as lighting curtains, indoor shutters, window glass and the like. Comprising a front ideal lens and a rear ideal lens in an array form, the front ideal lens and the rear ideal lens are a negative lens array and a positive lens array respectively, and the negative lens array is used for collecting outdoor natural light and conducting the outdoor natural light to the positive lens array through an intermediate medium; the positive lens array is used for refracting incident natural light and then deflecting the incident natural light to the indoor space. Natural light entering the window can be efficiently collected, light rays are evenly diffused to all directions in a room, indoor illumination is homogenized, indoor privacy is effectively protected, and the window is environmentally friendly and free of pollution.

Description

Technical field [0001] The present invention belongs to the design of the lighting system and the field of beam shaping, and the apparatus and method involving a natural light shape. Through the natural light homogenization device designed, natural light incident from the window can be evenly dispersed into various corners in the house, and the natural light is used to make indoor lighting, energy saving and emission reduction, improve energy utilization; and effectively protect indoor privacy, the device environmental protection No pollution, can be used as illumination curtains, interior shutters and windows glass, etc. Background technique [0002] my country's research and development of Natural Light Lighting Technology started in the 1960s and seventies, since the promotion of "green lighting" project in 1996, the natural light lighting this green energy concept is gradually entering the public's field of view, with the research of solar lighting technology Constantly, peop...
