Definitions
- the invention relates to laminated glazing, especially to laminated glazing incorporating electronic components.
- the invention relates more particularly to a method for powering an electronic component of such a laminated glazing, and a laminated glazing specially adapted to the implementation of this method.
- the invention therefore also aims to provide a method for the electrical supply of electronic components of laminated glazing, which slows down, or even annihilates, the aging of these glazings.
- a further object of the invention is to provide an installation comprising, on the one hand, a laminated glazing unit incorporating an electronic component and, on the other hand, a source of electric current connected to said electronic component, said installation being designed to slow down, even annihilate, the aging defined above the glazing.
- the subject of the invention is a method for the electric power supply of an electronic component of a laminated glazing unit, said laminated glazing unit comprising at least two superimposed glass sheets with the interposition of at least one thermoplastic interlayer and the component electronics being housed between the two glass sheets, the method according to which the electronic component is connected to a source of electric current via an electroconductive circuit, which is housed between the glass sheets; according to the invention, the method is characterized in that the source of electric current is controlled in time by a microcontroller.
- the laminated glazings used in the process according to the invention are of the type commonly used in the art, defined above. They generally comprise at least one pair of glass sheets between which a thermoplastic interlayer is sandwiched. The dimensions and shape of the glazing are not critical for the definition of the invention.
- the glazing can be indifferently planar or curved or have any form compatible with its destination.
- the thermoplastic interlayer serves to secure the two sheets of glass. It generally comprises a polyester film, which may advantageously be selected from polyvinyl butyral (PVB), copolymers of ethylene and vinyl acetate (EVA) and polyethylene terephthalate (PET).
- the interlayer may comprise a single polyester film. Alternatively, the interlayer may comprise a stack of several polyester films of the type described above.
- the thickness of the thermoplastic interlayer is not critical for the definition of the invention. The optimum thickness must be determined in each particular case by the skilled person according to various parameters, including the dimensions of the glazing, the destination thereof and the composition of said interlayer.
- the thickness of the thermoplastic interlayer is generally less than 3.5 mm, this dimension being however given purely by way of example and not limiting as to the scope of the invention.
- the glazing may comprise more than two superimposed glass sheets, alternating with thermoplastic interleaves.
- the selection of the electronic component will depend on the desired functionality.
- Optoelectronic components such as in particular light-emitting diodes (LEDs), photoresistors, photodiodes and vision sensors, for example of the CCD type (abbreviation well known in the English technique “Charge Coupled Device”) and CMOS (abbreviation well known in the art of the English expression “Complementary Metal Oxide Semiconductor”) are particularly useful because directly related to the optical appearance of the glazing.
- CCD abbreviation well known in the English technique "Charge Coupled Device”
- CMOS abbreviation well known in the art of the English expression "Complementary Metal Oxide Semiconductor”
- other electronic components can also be inserted to make complete electronic circuits. Depending on the type of components and the electrical conductors used, these circuits may or may not be visible.
- the glazing used in the invention may comprise a single electronic component. However, it may also include several electronic components, which is the most common case.
- the glazing contains several electronic components, these can all be identical.
- the glazing may comprise a plurality of different electronic components, exerting different functionalities.
- electronic component designates an individual electronic component or, globally, a set of several electronic components.
- Typical conductive layers have a thickness generally between 0.02 and 1 ⁇ , preferably between 0.02 and 0.5 ⁇ , more preferably between 0.2 and 0.4 ⁇ , and a surface resistance between 0 and 80 ⁇ / square, preferably between 4 and 50 ⁇ / square, more preferably between 4 and 20 ⁇ / square.
- the electroconductive circuit can or must be visible, invisible, transparent, translucent or opaque.
