Document Type and Number:
Japanese Patent JP6903498
Kind Code:
B2
Abstract:
To provide a daylighting device which maintains a light guide amount indoors at equal to or greater than a certain amount without depending on solar altitude, and which can prevent glare caused by reflection light.SOLUTION: A daylighting device reflects sunlight S and radiates reflection light R to a ceiling surface indoors, and includes a plurality of long thin plate-like slats 2 having opposing concave surfaces and convex surfaces and reflecting the sunlight S with the concave surfaces. Each slat 2 has a first curved part 21, a second curved part 22 and a third curved part 23. The first curved part 21 radiates the reflection light R of the sunlight S from first solar altitude to the ceiling surface. The third curved part 23 radiates the reflection light R of the sunlight S from second solar altitude which is lower than the first solar altitude to the ceiling surface. The second curved part 22 radiates the reflection light of the sunlight from the second solar altitude to the ceiling surface, and also, reflects the reflection light R radiated from the first curved part 21 or the third curved part 23 and suppresses glare caused by the reflection light R.SELECTED DRAWING: Figure 9
