A lamp cap with a spring cup for retaining a lamp burner, for which it is proposed that the spring cup has at least three spring legs which each have substantially only one degree of freedom. The spring legs are arranged such that the three degrees of freedom enable a displacement possibility of the spring cup in a displacement plane and are linearly independently aligned in this displacement plane.

Lamp cap, assembly of lamp burner and lamp cap, and method of fastening a lamp

In a process for mounting a single-capped electric lamp (1) in a lampholder (20) of a luminaire (22), use is made of a cap (3) having an end zone (9) in its shell (4) which in a mounted lamp is outside the lampholder. The end zone (9) is provided with relief (15) enabling a mounting tool (30) to seize the cap (3) with little force and nevertheless to have a firm grip onto the lamp. The position of the relief (15) may be related to the position of coupling device (10) present at the cap (3) for cooperation with the lampholder, enabling the tool (30) to approach the holder (20) with the cap (3) in a predetermined position. By the process it is counteracted that a lamp (1) having a cap (3) which is suited to be used in the process and a luminaire (22) having the holder (20), becomes damaged during assembling.

Method of placing a single-capped electric lamp in a lampholder,

A method for maintaining a sealed beam lamp unit comprising a quartz iodine lamp accommodated in an outer envelope. A sleeve-shaped cap which is made of a metal strip material surrounds the lamp pinch which is substantially rectangular in cross-section and to which a wire is secured which serves as the sole support for the lamp.
