Title
(EN) LED TUBE LAMP
(FR) LAMPE À TUBE À DEL
Abstract
(EN)
An LED tube lamp comprises a lamp tube (1); a first circuit board (2), disposed in the lamp tube (1) and having a plurality of light sources (21) mounted thereon; and two lamp caps (3), respectively disposed at both ends of the lamp tube (1) and having a power supply (5) disposed therein. The power supply (5) has a second circuit board (51) with a first surface (511) and a second surface (512) opposite and parallel to each other. The lamp cap (3) comprises a side wall (31), an end wall (32), and a slot (35) with a first rib (33). There is a coupling structure (331) protruded on the first rib (33) with respect to the first surface (511) of the second circuit board (51).

La présente invention concerne une lampe à tube à DEL comprenant un tube de lampe (1) ; une première carte de circuit imprimé (2), disposée dans le tube de lampe (1) et sur laquelle sont montées une pluralité de sources de lumière (21) ; et deux calottes de lampe (3), respectivement disposées aux deux extrémités du tube de lampe (1) et dans lesquelles une alimentation électrique (5) est disposée. L'alimentation électrique (5) présente une seconde carte de circuit imprimé (51) ayant une première surface (511) et une seconde surface (512) opposées et parallèles l'une à l'autre. La calotte de lampe (3) comprend une paroi latérale (31), une paroi d'extrémité (32), ainsi qu'une fente (35) ayant une première nervure (33). Une structure d'accouplement (331) fait saillie sur la première nervure (33) par rapport à la première surface (511) de la seconde carte de circuit imprimé (51).
