Description

Technical Field

[0001] The present invention belongs to the technical field of optics, and particularly relates to a uniform lighting device.

Background Art

[0002] The research and development of natural light lighting technology in China began in the 1960s and 1970s. Since the "Green Lighting" project became popular in 1996 until now, the concept of green energy of natural light lighting has gradually entered the public's vision. As the research on solar lighting technology deepens, people have a deeper understanding of the natural light collection lighting system. The direct sunlight in a day has different lighting intensities and angles depending on the morning and evening times. People can divide the change situation of the direct sunlight throughout the day into three lighting stages according to the included angle between the sun and the ground.

[0003] 1. Morning and evening sunlight: When the sun rises from the eastern horizon and when the sun sets on the western horizon in the evening, the included angle between the sunlight and the ground is 0° to 15°.

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

[0005] 3. Sunlight around 12 noon: Also called top light, it irradiates the ground vertically from top to bottom. The lighting angle of the sunlight at this time is often affected by the season. The sunlight around 12 noon in summer basically irradiates the ground vertically at 90°, and the projection of the ground object is very small. However, around 12 noon in other seasons, the sunlight irradiates from top to bottom at a nearly vertical angle. Around 12 noon in winter, its irradiation angle is even more deviated.

[0006] The angles at which the natural light of the above three lighting stages enters the room are different. The conventional daylighting curtain cannot guarantee that the natural light of each lighting stage can be evenly scattered into the room, and it is difficult to form a uniform irradiation effect throughout the day.

Summary of the Invention
