Abstract

L'invention concerne une source lumineuse utilisant des diodes électroluminescentes qui émettent une lumière blanche. Ces diodes sont montées sur un élément allongé comportant au moins deux surfaces sur lesquelles les diodes électroluminescentes sont montées. Cet élément allongé est thermo-conducteur et est utilisé pour refroidir les diodes électroluminescentes. Dans le mode de réalisation illustré, l'élément allongé est un élément tubulaire par lequel circule un agent caloporteur. Un dispositif de refroidissement ou de mise en mouvement du fluide, couplé à l'élément thermo-conducteur allongé, augmente le refroidissement des diodes électroluminescentes.
