Abstract

Disclosed is a low-pressure discharge lamp, particularly a compact fluorescent lamp comprising at least one discharge vessel that is inserted in a base. The base and the discharge vessel are connected via a joining material. According to the invention, the base is provided with at least one recess via which the joining material can be introduced after the discharge vessel has been inserted.

Claims (12)

1 . A low-pressure discharge lamp, in particular a compact fluorescent lamp ( 1 ) having at least one discharge vessel ( 2 ), which is inserted into a base ( 6 ), the base ( 6 ) and the discharge vessel ( 2 ) being connected via a joining compound ( 34 ), characterized in that the base ( 6 ) has at least one cutout ( 36 , 148 ), via which the joining compound ( 34 ) can be introduced when the discharge vessel ( 2 ) has been inserted.

2 . The low-pressure discharge lamp as claimed in claim 1 , the cutout ( 148 ) being formed in a bottom wall ( 150 ) of the base ( 6 ).

3 . The low-pressure discharge lamp as claimed in claim 2 , the cutout ( 148 ) being arranged centrally in the bottom wall ( 150 ) and being matched with a constriction ( 155 ) to the outer contour of the discharge vessel ( 2 ).

4 . The low-pressure discharge lamp as claimed in claim 1 , the cutout ( 36 ) being arranged between connecting webs ( 74 , 76 , 82 , 84 , 104 , 106 , 112 , 114 ) holding a base box ( 52 ).

5 . The low-pressure discharge lamp as claimed in claim 4 , the base box ( 52 ) accommodating electrical components, in particular an interference suppression capacitor and a glow starter.

6 . The low-pressure discharge lamp as claimed in claim 4 , at least two contact pins ( 28 ) and/or at least two connecting sleeves ( 30 ), in particular crimping sleeves for connecting a capacitor wire to a glow starter wire and an electrode wire, are fixed to the connecting webs ( 74 , 76 , 82 , 84 ; 104 , 106 , 112 , 114 ).

7 . The low-pressure discharge lamp as claimed in claim 6 , four contact pins ( 28 ) being fixed to the connecting webs ( 104 , 106 , 112 , 114 ).

8 . The low-pressure discharge lamp as claimed in claim 1 , the joining compound ( 34 ) being introduced into an area, at least sections of which are delimited by the discharge vessel ( 2 ) and the base ( 6 ).

9 . The low-pressure discharge lamp as claimed in claim 1 , the joining compound ( 34 ) being an adhesive or cement.

10 . The low-pressure discharge lamp as claimed in claim 1 , the base ( 6 ) being in one part.

11 . The low-pressure discharge lamp as claimed in claim 1 , the base ( 6 ) being matched circumferentially substantially to the contour of the discharge vessel ( 2 ).

12 . The low-pressure discharge lamp as claimed in claim 1 having a cover for covering the cutouts ( 74 , 76 , 82 , 84 , 104 , 106 , 112 , 114 ).
