Abstract

La présente invention concerne une lampe à DEL comprenant un corps de lampe (1), une carte de lampe PCB (2) et une plaque de diffusion (3). Le corps de lampe (1) comprend un corps principal de panneau de lampe (11) et des plaques de couverture (12) ; les plaques de couverture (12) sont fixement agencées au niveau des deux extrémités du corps principal de panneau de lampe (11) respectivement ; le corps principal de panneau de lampe (11) est doté d'une cavité de montage (4) et une surface étagée (5) est disposée entre deux côtés de la cavité de montage (4) et du corps principal de panneau de lampe (11) ; la plaque de couverture (12) est dotée d'un bloc de limitation en forme d'arc (6). La carte de lampe PCB (2) est agencée dans la cavité de montage (4) et la plaque de diffusion (3) est recouverte sur la cavité de montage (4) par le biais de la surface étagée (5) et d'un bloc de limitation en forme d'arc (6). La lampe à DEL nécessite peu de pièces et présente une structure simple. Des plaques de couverture (12) sont disposées au niveau des deux extrémités du corps principal de panneau de lampe (11) respectivement pour former un corps de lampe complet (1) ; une cavité de montage (4) est agencée sur le corps principal de panneau de lampe (11). Une carte de lampe PCB (2) est agencée dans la cavité de montage (4) ; une surface étagée (5) est agencée entre les deux côtés de la cavité de montage (4) et du corps principal de panneau de lampe (11) ; un bloc de limitation en forme d'arc (6) est agencé sur la plaque de couverture (12) ; une plaque de diffusion (3) et le bloc de limitation en forme d'arc (6) peuvent être recouverts sur la cavité de montage (4) par le biais de la surface étagée (5). De cette manière, une lampe à DEL est formée ; et la connexion entre la plaque de diffusion (3) et le corps de lampe (1) est simple et une connexion par vis ou d'autres connexions ne sont pas nécessaires et la plaque de diffusion peut être directement installée ou démontée sur le corps de lampe (1) de sorte que la lampe à DEL peut être démontée et assemblée de façon pratique.
