regenerative trigger circuits (class / ) ring or reversible counter (class / ) using bistable semiconductors having at least three electrodes or analogous complementary transistor circuits (e.g., avalanche transistor, scr's) (class / ) using bistable semiconductors having only two electrodes (e.g., tunnel diode...
diodes (leds) as a light source. moving head types can either be a bank of leds mounted on a yoke or more conventional moving head lights with the bulb replaced with an led bank. like other led instruments, they have high light output with lower power consumption. most led fixtures utilize three or...
