Une lampe fluorescente à DEL comprend un abat-jour (1), des diodes électroluminescentes (DEL) (2), un film réfléchissant (3), une carte de circuit imprimé (5), et un support de lampe (6). Plusieurs diodes électroluminescentes (DEL) (2) sont fixées sur la carte de circuit imprimé (5). Une surface d'émission de lumière des DEL (2) est revêtue par le film hautement réfléchissant (3) sauf pour les points d'émission de lumière, ou une surface des diodes électroluminescentes (2) est revêtue et imprimée par une matière hautement réfléchissante. Une couche isolante et une couche de circuit dans un substrat d'aluminium sont directement fixées sur le support de lampe (6) de dissipation de chaleur en aluminium, formant ainsi une structure intégrée de la carte de circuit imprimé (5) et du support de lampe (6). La présente invention résout les problèmes de faible transmittance de lumière, de luminosité irrégulière, et de faible dissipation de la chaleur existant dans un abat-jour en PC d'un tube de lampe à Del.
