Abstract

La présente invention concerne un dispositif d'éclairage à diode électroluminescente (LED) électrique qui utilise des composites d'aluminium carbonique. En particulier, dans les dispositifs d'éclairage à LED électriques connus auparavant, un trou d'installation pour une tige à rayonnement thermique est défini dans la position dans laquelle une LED est disposée sur un corps. Une tige à rayonnement thermique formée de composites d'aluminium carbonique est insérée dans le, et fixée au, trou d'installation du corps. Une surface sectionnelle de la tige à rayonnement thermique passe à travers le trou d'installation pour entrer en contact avec le substrat d'un module à LED. Ainsi, un rendement thermique du dispositif d'éclairage peut être sensiblement optimisé, et non seulement le volume total du dispositif d'éclairage peut être sensiblement réduit afin d'être léger, mais les coûts de fabrication de produits peuvent être sensiblement réduits également. De même, lorsqu'un rayonnement thermique est réalisé en utilisant la tige à rayonnement thermique qui est constituée des composites d'aluminium carbonique, l'effet de rayonnement thermique peut être environ deux à trois fois plus important que celui de l'aluminium pour le même volume. Ainsi, le dispositif d'éclairage à LED peut être produit en utilisant le corps principal d'un dispositif d'éclairage à lampe à décharge classique tel qu'il est. Donc, le gaspillage inutile de matériaux bruts peut être empêché. De même, bien que le corps soit formé en utilisant une résine synthétique par moulage par injection, le rayonnement thermique généré dans la LED peut être suffisant à travers une pluralité de tiges à rayonnement thermique formées de composites d'aluminium carbonique, produisant ainsi un éclairage à LED léger et peu coûteux et obtenant une diversité de conception.
