Abstract

L'invention porte sur une lampe à diodes électroluminescentes linéaire (1), laquelle lampe comporte : un module de diodes électroluminescentes (10), qui comprend un substrat long (11) et une pluralité d'éléments de diode électroluminescente (12) qui sont montés sur une première surface (11a) du substrat (11) ; un boîtier long (20) qui contient le module de diodes électroluminescentes (10) ; et une première base (50) qui est contenue dans le boîtier (20) et sur laquelle est disposé le module de diodes électroluminescentes (10). La première base (50) comprend : une première partie paroi (51) et une seconde partie paroi (52), qui prennent en sandwich le substrat (11) à partir de côtés latéraux dans la direction du côté court ; une pluralité de premières saillies (51a) qui font saillie à partir de la première partie paroi (51) vers la seconde partie paroi (52) ; et une pluralité de secondes saillies (52a) qui font saillie à partir de la seconde partie paroi (52) vers la première partie paroi (51). La pluralité de premières saillies (51a) et la pluralité de secondes saillies (52a) sont en contact avec la première surface (11a) du substrat (11), et les deux parties d'extrémité du substrat (11) dans la direction longitudinale comportent les premières saillies (51a) et/ou les secondes saillies (52a).
