Embodiment 1

[0048] see figure 2 , in (a), when the two films are attached together, the first film 102 is inlaid with a columnar array, and its bottom surface is a convex lens 110 bent from the first edge of the first film surface 130, and the transparent second film 104 is also inlaid There is a cylindrical array, but its top surface is a convex microlens 112 curved from the second edge of the second film surface 136, the first film 102 and the second film 104 are made of a first material with a refractive index N1, and all mosaic The cylindrical convex lens array is made of a second material with a refractive index N2, and the side surface 106 of the cylindrical mosaic part is opaque, and the opaque wall prevents the light entering the current cylindrical mosaic part 108 from entering its adjacent cylindrical mosaic part 108. Among all the rays entering this part, only the rays almost perpendicular to the lens plane can pass through the convex lens 110 and converge to the focal point 1...

Embodiment 2

[0052] see image 3 , the device consists of a trachea 304 connected to a transparent bag 320 spanning the entire surface of the first film 102 and the second film 104 at the opening 302, the bag functions like a rectangular prism positioned between the two films, Covering the entire surface area of ​​the film, the other side of the gas pipe 304 is connected to an air pump 306 with a control switch 316 which can be freely designed but has at least two states: state closed 314, the valve closes the end of the main pipe 308 Air cannot be released, so that the air tube 304 and transparent bag 320 can be filled with air using the air pump 306;

[0053] When the air pump 306 turns the control switch 316 to the state closed 314, the manual can press the air pump 306 with the hand 310 to inflate the transparent bag 320 through the air pipe 304. Because the gap 138 of the transparent bag 320 is usually very small, even if the area of ​​the transparent bag 320 may Large, the total vol...

Embodiment 3

[0056] see Figure 4 , all the microlenses are arranged as a lenticular lens 400, the lenticular lens 400 is an array of magnifying lenses or convex lenses, from the first film surface 130, the convex lens 110 looks rectangular, and the cross-sectional view is a plane on or below the rectangular plane The convex lens, convex lens 110 extends straight down into the first film 102 before being bent into a lens shape, the sides of the rectangular prism being the lens portion directly down into the first film 102 are also opaque to prevent light from passing through the multiple lenses , the convex lenses 110 are inlaid into the first film 102 in rows, and the distance between each row is different. If the film is viewed in a different direction, the rows of these lenses become columns. Because the microlenses only converge light in one dimension, the biconvex lens Converge the incident light into a parallel beam, so the focal area of ​​each lens is a line rather than a point, acc...

Abstract

The invention discloses a device and method for controlling optical transmission by using a micro-lens array. The device comprises a transparent first thin film and a second thin film having an inlaidcylindrical array; the bottom surface of the first thin film forms a first thin film surface; a convex lens with a bent first edge of the first thin film surface is located in the first thin film; the top surface of the second thin film forms a second thin film surface; a convex micro-lens with a bent second edge of the second thin film surface is located in the second thin film, and the convex micro-lens comprises two layers of thin films separated by air, wherein each thin film is inlaid in a convex micro-lens array; the first layer of thin film focuses incident light through a the micro-lens; the second layer of thin film includes a grid of an opaque region; when the light is not blocked, a micro-lens array in the second layer of thin film spreads the light to the other side of the thin film, so that the thin film looks transparent or semitransparent, and the thickness of an air layer can be controlled by a manual pump connected with the thin film, so that the light-operated effects of being fully transparent, or adjusting the brightness or completely shielding the light source are achieved.

Description

technical field [0001] The invention relates to a device and method for light transmission control, in particular to a device and method for light transmission control using a microlens array. Background technique [0002] Interactive and adaptive technologies are being implemented into buildings. Adaptive buildings are capable of controlling their own operations, such as heating, ventilation, air conditioning, lighting, and even security. The rise of new technologies allows users to control buildings through interactive interfaces. One focal point of home interaction technology is windows. Homeowners and businesses alike are eager for new technologies to help them achieve privacy upgrades, and be environmentally friendly and energy efficient. People want a convenient solution that will help them save energy and give them the privacy they need. For environmentalists, large windows are a target of criticism because they are one of the largest sources of energy loss in bui...
