Looking at the construction standards for these light concentrating and mining facilities, it has the function of concentrating sunlight and using it for indoor lighting, and the lower part has the function of blocking sunlight.

Here, the slats of the blind device are thin plates that converge and reflect light, and must be made of aluminum with a mirror-like surface on one side when confirmed with the naked eye or touch. The slat anti-glare surface must have the property of absorbing light to prevent glare.

However, if a thin sheet of aluminum forming the slat is maintained, there is a problem that the slat may be bent and damaged or even broken during use of the blind device. Additionally, a problem arises in that deformation occurs when the blind device is lifted and lowered in a bent state by the bent slat.

Additionally, in the process of adhering a film that increases the reflectivity of the slat, air pockets are created between the slat and the film, which makes the appearance of the slat unattractive, and there is a problem in that partial film peeling occurs due to the air pocket.
