LED optoelectronic glass is a high-tech composite material. Its specific material composition and characteristics are as follows:
1. Core Material Composition
Conductive Glass Base
Tempered glass is used as the base layer, with a translucent mesh circuit formed on the surface through an etching process. This design not only ensures the glass's strength but also provides a conductive path for the LED beads. For example, the LED glass developed by the German company LIF uses this technology, ensuring the concealment and conductivity of the circuit.
LED Chipset
High-density LED chips are directly encapsulated within the glass interlayer, with laser-etched circuits achieving precise connections. The chipset supports full-color dynamic display and boasts a light transmittance exceeding 80%, ensuring unimpeded daylighting in the building. For example, the optoelectronic glass curtain wall used in the Wuxi Jiangnan Joy City project consists of nine large sections of optoelectronic glass, each housing an LED chipset, creating a visually appealing experience for over 100,000 visitors.
Interlayer and Encapsulation Materials
PVB Film: Serving as an interlayer, PVB film securely bonds the conductive glass, LED chipset, and panel glass, while also providing explosion-proof, waterproof, and UV resistance. Its light transmittance reaches 99%, ensuring a clear display.
Aluminum alloy frame: Concealing integrated circuits, it protects the internal structure from environmental influences while enhancing the overall aesthetics. For example, in the Dubai Mall guardrail application, aluminum alloy frames are combined with photovoltaic glass to achieve a balance between safety and design.
Coated Conductive Layer
Through offline coating technology, a transparent conductive film is formed on the glass surface, enabling power control of LED light beads. This technology eliminates the problem of exposed wiring in traditional applications, making the glass surface completely transparent. For example, in the curtain wall application of Xintiandi Nanli in Huangpu District, Shanghai, the coated conductive layer ensures that the glass looks identical to a regular curtain wall when unlit, while displaying dynamic video effects when illuminated.
2. Technical Features and Advantages
High Transparency and Display Performance
LED photovoltaic glass boasts a light transmittance of over 80% and a penetration rate exceeding 99%, ensuring optimal lighting and visual quality for the building. Furthermore, it supports full-color dynamic display and high pixel density, producing detailed images. For example, in the FootLocker window display on the Champs-Élysées in Paris, photovoltaic glass has transformed advertising from static to dynamic, increasing consumer attention.
Protective Performance
Explosion-proof, waterproof, and UV-resistant: PVB interlayer and tempered glass structure give photovoltaic glass IP65-rated protection, making it suitable for use in complex environments.
Impact Resistance: The tempered glass substrate can withstand strong impacts, ensuring safety. For example, in the atrium installation of the Vincom Center in Vietnam, photovoltaic glass has withstood the test of heavy foot traffic and daily use.
Energy Saving and Environmental Protection
LED lamps have low power consumption, require no additional heat dissipation equipment, and have a lifespan of over 10 years, significantly reducing maintenance costs. For example, the Wuxi Jiangnan Joy City project reduced the energy consumption and cleaning costs of traditional curtain walls by using photovoltaic glass.
Design Flexibility
Customization: Supports customization of any shape, size, and color, up to 3 meters x 2 meters, to meet individual needs.
Special-Shaped Joints: Through parametric analysis and precise control, complex geometric shapes such as triangles and diamonds can be joined. For example, the diamond curtain wall of Wuxi Jiangnan Joy City, composed of 33 geometric shapes and 410 panels, demonstrates the advantages of photovoltaic glass in special-shaped designs.
3. Application Scenarios
LED optoelectronic glass is widely used in architectural curtain walls, interior decoration, and advertising displays:
Architectural curtain walls, such as the Shanghai World Expo's Automotive General Pavilion and the diamond curtain wall at Wuxi Jiangnan Joy City, achieve dual functions of lighting and advertising.
Interior decoration, such as the atrium installation at Vietnam's Vincom Center, enhances the artistic feel of the space.
Advertising displays, such as the FootLocker window display on the Champs-Élysées in Paris, attract customers with dynamic advertising.
Guardrails and signage, such as the Dubai Mall's guardrails, balance safety and aesthetics.
LED optoelectronic glass utilizes a composite structure of conductive glass, LED chipsets, a PVB interlayer, and a coated conductive layer to achieve a balance of high transparency, protective performance, and energy efficiency and environmental protection.
Its technological advantages make it an ideal choice for modern architectural design and are widely used in high-end commercial complexes, cultural venues, and public facilities.
