Title
(DE) LAMPE MIT MINDESTENS EINER LEUCHTDIODE
(EN) LAMP WITH AT LEAST ONE LIGHT-EMITTING DIODE
(FR) LAMPE COMPORTANT AU MOINS UNE DIODE ÉLECTROLUMINESCENTE
Abstract
(DE) Unter dem Gesichtspunkt der Energieeinsparung werden herkömmliche Leuchtkörper in steigendem Maße durch LEDs ersetzt. Je höher die Lichtausbeute gesteigert wird, umso höher steigt allerdings auch der Verlust durch abgestrahlte Wärme. Zur optimalen Abführung der entstehenden Wärme wird vorgeschlagen, dass bei einer Lampe (1, 30) mit mindestens einer LED (Light Emitting Diode) (4, 34) als Leuchtmittel, bestehend aus einem Lampenkörper mit einem die LED umgebenden Schirm (2, 32, 32a) und einem die LED tragenden Sockel (3, 33, 61), der Lampenkörper der Lampe (1, 30) vollständig aus einem keramischen Werkstoff besteht.
(EN) With consideration to energy savings, conventional illumination elements are being replaced by LEDs to an increasing degree. However, the higher the increase in light output, the higher the increase in losses due to radiated heat. To optimally dissipate the incident heat, it is proposed that in a lamp (1, 30) comprising at least one LED (Light Emitting Diode) (4, 34) as a illumination means, comprising a lamp body with a shield (2, 32, 32a) surrounding the LED and a socket (3, 33, 61) holding the LED, the lamp body of the lamp (1, 30) should be made entirely of a ceramic material.
(FR) Du point de vue des économies d'énergie, on remplace de plus en plus les luminaires traditionnels par des DEL. A vrai dire, la perte de chaleur perdue par rayonnement augmente d'autant plus qu'est plus élevée l'augmentation du rendement lumineux. Pour évacuer d'une manière optimale la chaleur produite, il est proposé selon l'invention que, dans une lampe (1, 30) comportant en tant que moyen d'éclairage au moins une DEL (diode électroluminescente) (4, 34), et constituée d'un corps de lampe ayant un écran (2, 32, 32a) entourant la DEL et un culot (3, 33, 61) portant la DEL, le corps de la lampe (1, 30) soit entièrement constitué d'un matériau céramique.
