Description

[Technical field]

[0001] The present invention relates to the technical field of optics, and in particular to a uniform illumination device. [Background technology]

[0002] China's research and development of natural lighting technology began in the 1960s and 1970s, and since the popularization of the "Green Lighting" project in 1996 to the present, the green energy concept of natural lighting has gradually entered the public's view, and as research into solar lighting technology has deepened, people have a deeper understanding of natural light harvesting lighting systems. The intensity and angle of direct sunlight throughout the day varies depending on the time of day, morning or evening, and people can divide the changing conditions of direct sunlight throughout the day into three lighting stages according to the angle between the sun and the ground.

[0003] 1. Morning and evening sunlight: When the sun rises above the eastern horizon, and when it sets below the western horizon in the evening, the angle between the sunlight and the ground is 0°~15°.

[0004] 2. Morning and afternoon sunlight: The angle between the sunlight and the ground in the morning and afternoon is between 15°~60°, which usually refers to the light between 8:00 am and 11:00 am and 2:00 pm and 5:00 pm, and the lighting intensity is relatively stable.

[0005] 3. Sunlight around 12 a.m.: Also known as top light, it shines vertically from top to bottom on the ground. The lighting angle of the sunlight at this time is often affected by the season. Around 12 a.m. in the summer, sunlight basically shines vertically downward at 90° on objects on the ground, and the projection of objects on the ground is very small. However, around 12 a.m. in other seasons, sunlight shines from top to bottom at an almost vertical angle, and around 12 a.m. in the winter, the irradiation angle is even more biased.

[0006] The angles at which the natural light of the above three lighting levels enter the room are different, and traditional daylight curtains cannot guarantee that the natural light of each lighting level can be scattered evenly throughout the room, making it difficult to create a uniform lighting effect in all weather conditions. Summary of the Invention [Problem to be solved by the invention]

[0007] In order to solve the problem that traditional daylight curtains cannot ensure that natural light at each lighting level can be uniformly scattered throughout the room, making it difficult to create a uniform illumination effect in all weather conditions, the present invention further proposes a uniform lighting device consisting of a single unit combining a lens and a sawtooth grid.
