TECHNICAL FIELD

[0001] The present application relates to a kind of homogenization lighting device, belong to optical technology field. BACKGROUND

[0002] The research and development of natural light illumination technology in China started in the 1960s and 1970s, since the "green lighting" project has been popularized since 1996, the concept of natural light illumination as a green energy is gradually entering the public view, with the deepening of the research on solar lighting technology, people have a deeper understanding of natural light collection lighting system. The intensity and angle of direct sunlight in a day are different due to the different time of day, people can divide the change of direct sunlight throughout the day into three illumination stages according to the different angles formed by the sun and the ground:

[0003] 1. Early morning and evening sunlight: when the sun rises from the eastern horizon and the sun sets below the horizon in the evening, the angle between the sun and the ground is 0°-15°;

[0004] 2. Morning and afternoon sunlight: the angle between the morning and afternoon sunlight and the ground is between 15° and 60°, which usually refers to the light at 8am to 11am and 2pm to 5pm, the illumination intensity is relatively stable;

[0005] 3. Midday sunlight: also known as top light, which shines vertically from top to bottom. The illumination angle of midday sunlight is often affected by the season, and in summer, the midday sunlight is basically perpendicular to the ground, and the projection of the ground scene is very small. In other seasons, the sun shines from above at a nearly vertical angle, and in winter, the angle of incidence is more biased.

[0006] The angles of natural light entering the room in the above three illumination stages are different, and the traditional daylighting curtain cannot ensure that the natural light in each illumination stage can be uniformly scattered into the room, and it is difficult to form a full-time homogenization illumination effect. SUMMARY

[0007] To solve the problem that the traditional daylighting curtain cannot ensure that the natural light in each illumination stage can be uniformly scattered into the room, and it is difficult to form a full-time homogenization illumination effect, a lens and sawtooth grating combined single homogenization lighting device is proposed.
