Method for making construction material two-side surface light extraction and LED surface light source for lighting

Abstract

The invention provides a method for making both sides of architectural decoration material lighting and lighting-used LED surface light source thereof, belonging to building construction filed. The invention is characterized in that an upper transparent substrate and a lower transparent substrate are equipped, an LED point light source is positioned between the upper and the lower transparent substrates, and an optical membrane is coated on or an optical reflecting and / or diffusing structure is etched on part of the upper and / or lower transparent substrates. By changing the optical structure of part of the transparent substrates, the light emitted from the LED light source is partially emerged from the upper transparent substrate, while the other part of light is emerged from the lower transparent substrate. The invention changes the optical structure of the transparent substrates, so that observer can observe light simultaneously emerged from the upper and the lower sides of the light source. Meanwhile, the invention adopts transparent conductive coating and direct illumination of LED, so as to improve the transparency of the building to be decorated and meet the large-size lighting requirements. The invention can be widely used in various types of glass curtain walls of buildings or architectural decoration materials.

Description

technical field [0001] The invention belongs to the field of general building construction, and in particular relates to a glass curtain wall which adopts LED as a light source and can be applied to buildings to realize photoelectric lighting decoration. Background technique [0002] LED (Light Emitting Diode) is a light-emitting diode, which is composed of a PN layer and a light-emitting layer in it. With different materials of the light-emitting layer, its light-emitting color is different. [0003] Since the emergence of nitride LEDs in the early 1990s, the luminous efficiency of LEDs has made a qualitative leap. Then the successful development of blue LED made white LED possible. The successful development of the physical and chemical process and process technology of white light LED provides a reliable guarantee for the realization of various color LED light source products. [0004] In recent years, the high-power LED manufacturing process and the successful resoluti...

AI Technical Summary

Problems solved by technology

[0009] The structure is simple and easy to operate, but the decorative effect is not good, especially during the day when the wires hang outside the building, which has a great impact on the overall appearance of the building

[0010] 2. Gradient wall panels or wall strips with LEDs as backlights have large thickness, low transparency, complicated drive control, and relatively high cost;

[0013] This has the following disadvantages: the decorative pattern cannot be displayed, only a single light source; the optical cooperation between LED and glass is difficult, and every time it is used, it is necessary to make corresponding optical design for glass and LED to meet the optical requirements , which brings trouble to the application; in addition, due to the attenuation of the LED light source, the size of the surface light source is subject to certain restrictions, and the light uniformity is also subject to certain restrictions

[0018] 1. The electrode pins are metal or alloy wires. As the number of LED components used increases, a dense and complex metal wire network will inevitably be formed on the glass curtain wall, which will affect the transparency and external aesthetics of the glass curtain wall to be decorated;

[0019] 2. For occasions that require different luminous characteristics, the wiring structure is too complicated and the process is quite difficult, resulting in relatively high costs. For large-area glass curtain walls, it is difficult to connect wires between modules, so in actual engineering There are bound to be many constraints in the application

[0020] In addition, due to the unidirectionality of light emitted by LED light source devices, the light sources of the above-mentioned technical solutions can only emit light from one side. If it is used as lighting for large buildings such as curtain walls, observers cannot see the effect of the light source on both sides of the light source at the same time.
