Abstract

The present invention provides a lamp fixing piece, a lamp base and a socket for the lamp fixing piece, it is capable of mounting a lamp at an exact position by using the lamp fixing piece and fixing the lamp base in the socket temporarily. The lamp fixing piece (10) is composed of a lamp base (30) embedded on an outer side of an electrode locating on one end side of the lamp (50) and a socket (20) having an insertion part (22) for being inserted by the lamp base. The lamp base (30) is provided with an inclined part (31b) having a narrow front width relative to the insertion direction of the insertion part and a front end part (31a) formed with a constant width, and the front end part is formed with an annular fastening groove (35). In the insertion part of the socket for the lamp base, aninclined part (22b) and a front end insertion part (22a) are formed corresponding to the appearance shape of a bellying part of the lamp base, the inner wall of the front end insertion part is provided with a fastening body (26b) with a turnover mode by an elastic force, wherein the fastening body and the fastening groove are fastened with each other.

Description

technical field [0001] The present invention relates to a lamp fixture, a lamp holder and a socket constituting the lamp fixture, more specifically, to the following lamp fixture, a lamp holder and a socket constituting the lamp fixture: the lamp fixture A member connects a lamp such as a xenon lamp, a mercury lamp, a metal high-light lamp, etc. provided with electrodes at both ends of a luminous tube sealed with high-pressure gas to a power supply unit, and fixes the lamp in a predetermined posture, that is, The outer periphery of the lamp is fixed at a position of a predetermined horizontal plane and a position perpendicular to the horizontal plane. Background technique [0002] Seal the high pressure gas inside the luminous tube. In addition, a xenon lamp will be described as an example of a high-pressure lamp in which electrodes are respectively provided at both ends of the arc tube. Such as Figure 9 As shown, the xenon lamp 50 has a structure in which the front end o...
