Abstract (en)
[origin: WO2021176302A1] The invention relates to a light-emitting-diode lighting system that is at once powerful, robust, durable and has a protection index of up to IP69, while still keeping a low production cost. It consists of an insulated metal substrate, on which at least one light-emitting diode is deposited, and supplied with power via a cable or a connector. The circuit obtained is then enclosed within a heat-shrinkable sheath, which will remove the air and will dissipate the heat from the substrate and the diodes in an optimal manner, its heat-dissipation capability being of the order of ten times that of air. Each of the ends will then be overmolded, in order to make the system sealtight and robust. It is possible to take advantage of the overmolding to add a sealing lip around the connector, and specific voids allowing various modes of attachment, individually or per group. The device according to the invention is intended for domestic, industrial or horticultural lighting, depending on whether a translucent or transparent substrate is used.
