Low-Pressure Discharge Lamp
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.
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 ).
