FIELD: lighting. ^ SUBSTANCE: mechanical scanning device contains a fixed support, brightness modulate point light sources, devices for light sources dislocation, devices for connection between the fixed support and light sources, light sources power supply devices, a mechanisms for point light sources motion. A mechanical vibration system used as mechanisms for point light sources motion and connection between the fixed support and light sources, which linear velocity in its connection to the fixed support points is zero. The vibration system activated with light sources motion mechanisms at frequency, equal to the system own frequency. For brightness modulate point light sources power supply used flexible conductors, changing form the fixed support to the vibration system in dislocation points of devices, which provide connection between the fixed support and the vibration system. ^ EFFECT: decrease in efforts which are necessary for the system starting up and maintaining specified vibration amplitude, vibration frequency increase, the system reaction on the fixed support forces decrease. ^ 14 cl, 29 dwg |
