Title
(EN) OPTOELECTRONIC DEVICE OF THE LED (LIGHT EMITTING DIODE) TYPE OR THE LIKE
(FR) DISPOSITIF OPTOÉLECTRONIQUE DE TYPE DEL (DIODE ÉLECTROLUMINESCENTE) OU SIMILAIRE
Abstract
(EN)
Optoelectronic device of the LED (light emitting diode) type or the like, comprising at least two emitters (20,21,22), the at least two emitters are contained within an outer transparent envelope (12), so as to allow the passage of the light generated by said at least two emitters. Each emitter is configured in such a way as to emit a source of white light, each at a different colour temperature.
(FR)
Le dispositif optoélectronique de type DEL (diode électroluminescente) ou analogue comprend au moins deux émetteurs (20,21,22), lesdits au moins deux émetteurs étant contenus dans une enveloppe externe transparente (12), de manière à permettre le passage de la lumière générée par lesdits au moins deux émetteurs. Chaque émetteur est configuré de manière à émettre une source de lumière blanche, chacune à une température de couleur différente.
