Electric lighting column with motorized light bulb changing, use mobile bulb support running on column rack and pinion system transporting bulb from low level into high energized position

摘要

A support (6) for the bulb base (7) is tronconic and cooperates with a complementary tronconic location of a fixed bulb housing (2). The support (6) and the location (5) have complementary parts in electrical contact. The support (6) has clip fixings on an end of a rod fixed to a mobile block (3). An electric motor (17) fed from a battery is controlled via a telecontrol sensor (19).. Electric lighting column with motorized bulb replacement, is of the type having a support (6) for a bulb base (7) mounted on a mobile block (3) arranged to be displaced by a motorized drive between a high operational position, with applied voltage, and a low de-energised bulb change position. The mobile block (3) has an electric motor (17) driving a toothed wheel (25) along a rack (26) mounted on the body (1) of the lighting column. The block (3) has a guide system (30) cooperating with complementary parts (31) on the column body (1). The motors output shaft drives via pinions a conic pinion (23) in contact with a toothed wheel (24) carried on a face of a toothed wheel (25) linked to a rack (26) fixed to the light column.
