Abstract
A fluorescent lamp, particularly of annular shape, with a tube-shaped disrge vessel has a base with contact pins, in which the two ends of the vessel face each other. The contact pins are essentially arranged in the annular plane of the lamp on both sides of the base. The mount belonging thereto has a U-shaped profile. The arms of the mount are provided with recesses for taking up and making contact with the contact pins of the base. This makes possible a linear motion when inserting the base into the mount. Retaining springs on the mount and recesses on the base belonging thereto make possible a locking of the base with the mount. Another advantage is the small structural height of the lamp including the mount.
Claims9
A low-pressure discharge lamp comprising:
- a tube-shaped discharge vessel defining a lamp plane and having two ends facing each other, an electrode sealed at each of the ends of the discharge vessel,
- a base for receiving the two end of the discharge vessel, said base having base contacts arranged substantially in the lamp plane and comprising an elongated, square-shaped central piece with two side walls lying opposite one another and oriented essentially vertically to the lamp plane and two cylinder-shaped extensions disposed on two front sides of the central piece for taking up the two ends of the discharge vessel, two pins project as base contacts from each of the two side walls of the central piece.
A mount for a low-pressure discharge lamp with a base having pin contacts, said mount comprising a U-shaped housing having a groove for receiving a lamp base, said housing including two arms having opposing side walls, each of the arms having two slot-type recesses, and spring-type contacts arranged within said recesses for making contact with the corresponding pin contacts of the base.
