Problems solved by technology

However, due to the complex structure and high process requirements of this type of glass, and the integrated structure of liquid crystal film and glass, once damaged, it is not easy to repair, so its promotion in architectural applications is also limited.
It is worth noting that the above luminous or dimmable glass can only be designed for regular-shaped rectangular, square and other glass doors and windows, and with the diversification of building shapes and functions, there are more and more irregular shapes. Doors and windows appear, and doors and windows with curved edges are one of them. However, existing luminous and dimmable glass products are rarely designed for the shape of architectural doors and windows with curved edges.

specific Embodiment 1

[0099] Such as image 3 As shown, the black thin solid line represents a drop-shaped building door and window quartz light-transmitting plate composed of semicircles and triangles. Through screen printing, micron-level dimming microstructure dots are attached to the surface of the light-transmitting plate, and the dots are laid on the The entire surface of the light-transmitting sheet. After the arc edge of the drop-shaped light-transmitting plate is polished, an LED light source light bar is placed on the arc edge. The light bar substrate is a flexible substrate. The pitch is 0.3mm. The central wavelength of the LED light source light bar is 450nm, 525nm, and 620nm. The thickness of the transparent plate and the luminous size of the LED light source in the thickness direction of the plate are much smaller than the length of each side of the transparent plate. In addition, the light intensity distribution of the LED light source satisfies the characteristics of a Lambertian ...

specific Embodiment 2

[0142] Such as Figure 4 As shown, the black thin solid line represents a drop-shaped building door and window light-transmitting plate composed of semicircle and triangle. Optical microstructure dots, and the dots are laid on the entire surface of the light-transmitting sheet. After the two straight sides of the drop-shaped light-transmitting plate are polished, LED light-emitting light strips (light sources 1 and 2) are placed respectively. The substrate of the light strip is a flexible substrate, and the shape of the light strip fits the outer contour of the arc edge of the light-transmitting plate. The distance between the light bar and the arc edge is 0.2mm. The central wavelength range of the LED light source light bar is 450nm, 525nm, and 620nm. The thickness of the transparent plate and the luminous size of the LED light source in the thickness direction of the plate are much smaller than the length of each side of the transparent plate. In addition, the light intens...

Abstract

The invention relates to a dimmable light-emitting plate suitable for building doors and windows with arc edges. The body of the dimmable light-emitting plate is a light-transmitting plate, wherein the light-transmitting plate comprises at least one arc edge and any straight edge so as to define any closed shape; one or more groups of strip-shaped light sources are arranged on any one side or multiple sides of the light-transmitting plate to form single-side light incidence or multi-side light incidence; each group of strip-shaped light sources mainly comprises a flexible light bar substrate and a plurality of LED point light sources; micron-sized dimming microstructure lattice points are attached to the surface of one side or two sides of the light-transmitting plate. When the light source emits light, light enters the light-transmitting plate from the edge where the strip-shaped light source is arranged to be totally reflected and spread, and the light is scattered when encountering the dimming microstructure lattice points, and therefore doors and windows embedded into the light-transmitting plate are made to emit light evenly to achieve illumination. When the light source is adjusted, the luminous intensity of the light-transmitting plate is changed, so that the indoor illumination intensity is adjusted. The light-transmitting plate is favorable for realizing uniform light emitting and dimming of building doors and windows with arc edges.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a light-adjustable light-emitting plate suitable for building doors and windows with arc edges. Background technique [0002] With the continuous improvement of people's demand for building intelligence, architectural glass with multi-functional integration features is gradually favored by the market. In recent years, architectural luminous glass that can realize indoor lighting or adjust indoor light intensity has become a research hotspot because it can significantly improve the comfort of people's home and office environments. The function of this kind of architectural light-emitting glass to realize lighting or adjust indoor light intensity mainly depends on the integration of photoelectric technology. At present, the common light-emitting glass using photoelectric technology in the market mainly includes LED dot matrix photoelectric glass, LED flat lighting glas...
