(Dichroic LED Glasses laminated by Righetti

Dichroic LEDGlass is a new composite material

Composite material

Composite materials, often shortened to composites or called composition materials, are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct at the macroscopic or...

 which is based on the technology of transparent LED embedded glass

Transparent LED embedded Glass

Transparent LED-embedded glass is a new composite material containing light-emitting diodes . It is used as building material and as glass type for many different products. This new technology enables materials, new applications in electronics and architecture...

. Dichroic LED glasses differ from transparent Ledglass

Ledglass

Ledglass is a building material which contains some functional electronics, light-emitting diodes. The LEDGlass and its technology is described in different articles, It allows for example glass facades to be used as marketing area or windshield glasses to be used as display...

: The reflected colour of the LED Glass is a function of the angle of light

Light

Light or visible light is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light has wavelength in a range from about 380 nanometres to about 740 nm, with a frequency range of about 405 THz to 790 THz...

 reflection

Reflection (physics)

Reflection is the change in direction of a wavefront at an interface between two differentmedia so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves...

. This is caused by a dichroic

Dichroism

Dichroism has two related but distinct meanings in optics. A dichroic material is either one which causes visible light to be split up into distinct beams of different wavelengths , or one in which light rays having different polarizations are absorbed by different amounts.The original meaning of...

 interlayer material which causes visible light to be split up into distinct beams of different wavelengths.

Dichroic LED glass is produced by laminating

Laminated glass

Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral , between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high...

Light-emitting diode

A light-emitting diode is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting...

 interlayers between glass by means of vacuum bagging

Composite material

Composite materials, often shortened to composites or called composition materials, are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct at the macroscopic or...

. The history of vacuum lamination of sputtered

Sputter deposition

Sputter deposition is a physical vapor deposition method of depositing thin films by sputtering, that is ejecting, material from a "target," that is source, which then deposits onto a "substrate," such as a silicon wafer...
