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

[0038] Embodiment 1: as attached figure 1 As shown, this embodiment provides a monolithic natural light homogenization lighting device based on the combination of a single plane and a convex free-form surface, including two front and rear surfaces in the form of arrays, the first surface is a single plane, such as image 3 As shown in (b), the second surface is a convex freeform surface array, such as image 3 As shown in (a), the single plane is used to collect outdoor natural light, and transmit it to the convex free-form surface array through the intermediate medium of the same material between the two sides; the convex free-form surface array is used to deflect the incident natural light through the inclined surface and then deflect it to the indoor space. Each convex free-form surface array includes n unit structures, where n is a natural number greater than or equal to 1.

[0039] More specifically: the front and rear surfaces in the form of arrays respectively realize...

Embodiment 2

[0046] Embodiment 2: On the basis of the device in Embodiment 1, a single-chip natural light uniform lighting method based on the combination of a single plane and a convex free-form surface is designed, including:

[0047] The outdoor natural light is collected by a single plane, and transmitted to the convex free-form surface array through the intermediate medium of the same material between the two sides;

[0048] The convex free-form surface array deflects the incident natural light to the interior space after refraction.

Embodiment 3

[0049] Embodiment 3: as attached Figure 4 As shown, this embodiment provides a monolithic natural light homogenization lighting device based on the combination of a single plane and a concave free-form surface, including two front and rear surfaces in the form of arrays, the first surface is a single plane, such as Figure 6 As shown in (b), the second surface is a concave freeform surface array, such as Figure 6 As shown in (a), the single plane is used to collect outdoor natural light, and transmit it to the concave free-form surface array through the intermediate medium of the same material between the two sides; the concave free-form surface array is used to deflect the incident natural light to the indoor space after refracting through the inclined surface. The concave free-form surface arrays all include n unit structures, where n is a natural number greater than or equal to 1.

[0050] More specifically: additional phase modulation of the incident light by the second...

Abstract

The invention discloses a natural light homogenization lighting device and method of a single plane and a free-form surface or a sawtooth grating. The natural light homogenization lighting device and method can be used for lighting curtains, indoor shutters, window glass and the like. Comprising a front array surface and a rear array surface, the first surface is a single plane, and the second surface is a free-form surface array or a sawtooth surface array; the single plane is used for collecting outdoor natural light and conducting the natural light to the free-form surface array or the sawtooth surface array through an intermediate medium made of the same material between the two surfaces; the free-form surface array or the sawtooth surface array is used for refracting incident natural light through the inclined surface 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 indoor directions, indoor illumination is homogenized, indoor privacy is effectively protected, and the window is light, thin, easy to produce in quantity, 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 single-chip 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 thin, easy to mass-produce, environmentally friendly and pollution-free, and can be used as lighting curtains, indoor shutters, and window glass. 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. ...
