Dual-functional louver blade

Abstract

The invention relates to a dual-functional louver blade which comprises a blade and an overturning mechanism thereof. The dual-functional louver blade is characterized in that one surface of the blade is a sun shielding surface which reflects solar ray irritated thereon back to the outdoor; the other surface of the blade is a light guiding surface which leads all or some solar ray irritated thereon to the indoor; the overturning mechanism drives the blade to rotate and leads the positions of the sun shielding surface and the light guiding surface to be mutually changed; the sun shielding surface of the blade is provided with micro-teeth; and all or some light guiding surface of the blade is provided with the micro-teeth. The dual-functional louver blade has the benefit effects that a louver sun shielding and light guiding system which is formed by the dual-functional louver blade with random cross section shapes can control the optimization of the reflex reflection and the deflexion leading quantity of the direct sunlight according to the change of seasons and the specific requirement of users, overcome the requirement contradiction of the sunshine in summer and in winter, keep high perspective ratio whatever the solar altitude angle is high or low, and meet the requirement of the visual communication between users and scenery outside the window.

Description

technical field [0001] The invention relates to a louver structure of a louver sunshade and light guide system, and more specifically relates to a double-function louver. Background technique [0002] Chinese utility model patent "A Multifunctional Venetian Blade" (Patent No.: CN2844378) discloses a louver blade, one side of the blade is set as a black heat-absorbing surface, and the other side is set as a silvery white or white reflective surface. Reflect the heat of solar radiation back to achieve a cooling effect. When the room temperature is low, the heat-absorbing surface of the blades faces the window to absorb the heat of solar radiation and warm the room. Chinese utility model patent "A Hollow Blind that is Warm in Winter and Cool in Summer" (Patent No.: CN201196008) discloses a curved louver blade, the convex surface of the blade is coated with sunlight reflective coating such as pure aluminum or tin metal; the concave surface of the blade is coated with solar selec...

AI Technical Summary

Problems solved by technology

However, the louver sunshade and light guide system composed of these louver blades cannot solve the problems of seasonal changes and specific needs. When the sun is at a low altitude angle, the louver sunshade light guide system needs to maintain a high perspective and introduce more sunlight. For indoor lighting, the louvers need to be closed because glare cannot be prevented. In addition, there is no easy and fast method for determining the micro-teeth on the surface of the louvers with arbitrary cross-sections.
