Photo luminescent

Photoluminescence is a particular characteristic of a material class named “smart materials”. These materials transform the input energy into a new form of output energy (photovoltaic, piezoelectric, photoluminescence, electrostriction).

According to the definition of “encyclopedia of chemistry technology” smart materials are: “those objects and structures which perceive the ambient effects, examine information and then react to the ambient” (M. Addington, D. Schodek, Smart Materials and New Technologies, Architectural Press Elsevier”)

The fundamental characteristics of a “smart” material are:

- Immediacy, they respond in real time;
- Transitoriness, they respond to more than one state of the ambient;
- Auto-activation, intelligence acts inside the material and not outside)
- Selectivity, their response is different and predictable;
- Uniqueness, they strictly respond to the activator event.

Quantum NRJ developed for Niamè of HEKA group a particular application based on Light-inside® proprietary technology.
This technology allows the transfer of luminescent proprieties to crystal, giving active characteristics to the object “door”.
The door becomes then an interactive and multifunctional module with the ambient of the home.

During the phase of releasing the energy absorbed, the light emission is calibrated in function of the adapting curve of human eye.
The result is a moderate presence during the night, or a truly lighting signal in case of a sudden black-out.

In spite of the large number of difficulties encountered, Light-Inside® technology has been developed paying maximum attention to safety and to environmental preservation.
This technology differs from the other systems because of its constituent characteristics:

The absence of radioactivity


The absence of heavy metals


The absence of toxic compounds
