Socket for fluorescent lamps with limited light exit angle

The innovation relates to sockets for fluorescent lamps with a limited light emission angle. Fluorescent lamps ¹ , which are provided with a reflective layer on part of their circumference, have the advantage "that the collected dust is given a certain direction of radiation and in this way the luminous power of the lamp is better used, in order to avoid the failure of the lamp To direct lamps in a certain direction, i.e. to mount the lamps usually attached to bars or walls in an inclined position, sockets are used which can be rotated around their axis and adjusted at the desired angle to adjust the angle of incidence.

The previously known versions that this axial Verstellunf of the tubes are more or less complicated and the adjustment is more difficult because the adjustable

prevented and still an easy setting of the desired Direction of light failure allows. Above all, "the construction of the innovation consists of simple, and therefore inexpensive manufacturable ropes.

G-em according to firing are on part of the socket plate bores or depressions in the vicinity and a locking pin on the bracket for engaging in one of the bores or depressions resiliently attached. The fitting plate, which is pivotably mounted on the bracket or on the bracket, is located purposefully only with its middle part against the Ealtewinkel while the outer rope is arranged at a certain distance from it. In this outer part are the Holes or recesses provided for the engagement " of the locking pin are determined.

f> he Bastatift is expedient on one on the outside attached to the bracket's attached leaf spring and protrudes through an opening of the bracket. The leaf spring is advantageously on the axle bolt of the mounting plate attached, preferably by riveting. As a result of this arrangement, the fluorescent tube can be easily pivoted after the spring-loaded locking pin has been withdrawn and is after. : Letting go of the pin held by these in the set position. The dtift is useful on the one against the socket plate adjacent end conically shaped or rounded, so that it automatically moves into the bores or recesses the fitting plate impresses. Instead of a leaf spring, a spiral spring can naturally also be installed on the inside of the Bracket can be arranged, or some other spring

be used. The spiral or leaf spring can be connected to any ■ point on the bracket.
