FIELD: physics, optics.SUBSTANCE: invention relates to a method and a device for transmitting radiation to a dental object from pulsed light-emitting diodes (LEDs) through at least one light guide. Each LED (12, 14) is associated with a first light guide (16, 18) having a first and a second interface plane (20, 22, 24, 26). The light guides are directed by their first interface planes towards the corresponding stationary LED. The second interface planes are located on a closed path. The second interface planes (24, 26) are associated with the interface plane (44) of the second light guide (42). The second light guide (42) in accordance with the timing of the on LEDs (12, 14) can be directed towards the second interface plane (24, 26) of the first light guide (16, 18) of at least one on LED.EFFECT: achieving high luminous efficiency, minimising delay periods and simple design.15 cl, 6 dwg |
