Description

113

This invention relates to lighting technology and relates to pivoting lighting devices, mainly rail vehicles.

The purpose of the invention is to simplify the design and increase reliability.

Figure 1 shows a spotlight with a deflectable luminous flux, general view; figure 2 - the same (without the rear edge), rear view; on fig.Z - bushings, cross section.

The searchlight with a deflectable light flux includes a housing 1, a reflector 2, a light source 3, an actuating mechanism 4 of reciprocating motion and a driving member 5.

A reflector with a fork 6, bushings 7 and a roller 8, having a rigid connection between them, can be rotated around a vertical axis mounted in a bearing assembly 9 fixedly mounted in the housing of the searchlight and equipped with stops 10.

Coaxially with plug bushings sitting on rollers 11, L-shaped levers 12 with free-hanging ends 13 are installed. Distribution beam 14 is installed on the bearing unit, having two diametrically opposite pins 15 and 16, one of which is connected to the actuator mechanism.

In the neutral position of the spotlight, the ends of the 13 L-shaped arms 12 are pressed against the Rods 15 and 16 by a spring 17 mounted between the housing of the spotlight and the reflector. At the ends of the sleeves 7, the forks 6 have grooves 18, and on the L-shaped levers there are cam projections 9 entering into these grooves.

The device works as follows.

Depending on the required right or left deviation of the luminous flux, the actuator 4 of reciprocating movement through the driving member 5 and the pin 1 turns the distribution box 14. When turning the latter, pin 15 or 16 deflects the right or left end of the 13 L-shaped bar 12 and through the sleeves 7, Mr. oh levers 12 and roller 1 rotates the reflector 2 in the vertical plane

until the cam lug 19 of the L-shaped lever 12 selects the entire free stroke in the groove 18 of the sleeve 7.

Further action of the drive unit 5 on the pin 16 of the distribution arm 14 through the end of the 13 L-shaped lever 12 causes the reflector 2 to rotate in a horizontal plane until pin 15 or 16 (depending on the direction of rotation) comes into contact with one of the stops 10.

After switching off the actuator 4, the drive unit 5 returns the reflector 2 of the projector to the neutral position under the influence of the actuator spring.
