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

[0040] Embodiment 1: as attached figure 1 As shown, this embodiment provides a natural light homogenization lighting device based on the positive and positive combination of double lenses, including two front and rear positive lenses in the form of arrays, which are respectively the first positive lens array and the second positive lens array, and the first positive lens array The lens array is used to collect outdoor natural light, and conduct it to the second positive lens array through the intermediate air layer; the second positive lens array is used to deflect the incident natural light to the indoor space after refraction; the first positive lens array and the second positive lens array Each includes n unit structures, and one-to-one correspondence, n is a natural number greater than or equal to 1.

[0041] Wherein, the distance between the centers of the first positive lens array and the second positive lens array is greater than the sum of the focal lengths of the two ...

Embodiment 2

[0050] Embodiment 2: On the basis of the device in Embodiment 1, a natural light homogenization lighting method based on the positive and positive combination of double lenses is designed, including:

[0051] Outdoor natural light is collected by the first positive lens array, and transmitted to the second positive lens array through the intermediate air layer;

[0052] The second positive lens array deflects the incident natural light to the indoor space after refraction.

Embodiment 3

[0053] Embodiment 3: as attached image 3 As shown, this embodiment provides a natural light homogenization lighting device based on the positive and positive combination of double lenses, including two front and rear positive lenses in the form of arrays, which are respectively the first positive lens array and the second positive lens array, and the first positive lens array The lens array is used to collect outdoor natural light and conduct it to the second positive lens array through the intermediate air layer; the second positive lens array is used to deflect the incident natural light to the indoor space after refraction. Both the first positive lens array and the second positive lens array include n unit structures, and there is a one-to-one correspondence, and n is a natural number greater than or equal to 1.

[0054] Wherein, the focal point of a single unit of the first positive lens array falls on the center of a single complete positive lens unit of the second posi...

Abstract

The invention discloses a natural light homogenization lighting device and method based on positive and positive combination of double lenses. The natural light homogenization lighting device and method can be used as lighting curtains, indoor shutters, window glass and the like. Comprising a first positive lens array and a second positive lens array, the first positive lens array is used for collecting outdoor natural light, and the outdoor natural light is transmitted to the second positive lens array through an intermediate medium; the second positive lens array is used for refracting the 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 invention belongs to the field of lighting system design and light beam shaping, and relates to a device and method for natural light shaping. Through the designed natural light homogenization lighting device, the natural light incident from the window during the day can be evenly diffused to all corners of the house, making full use of natural light for indoor lighting, saving energy and reducing emissions, and improving energy utilization; and effectively protecting indoor privacy, the device is environmentally friendly Non-polluting, it can be used as lighting curtains, interior blinds and window glass, etc. Background technique [0002] my country's research and development of natural light lighting technology started in the 1960s and 1970s. Since the promotion of the "green lighting" project in 1996, the green energy concept of natural light lighting has gradually entered the public's field of vision. With the research on solar lighting techno...
