METHODS TO MEASURE POWER INTENSITY IN LIGHT SOURCES POWER SUPPLY DEVICES

摘要

FIELD: electricity. ^ SUBSTANCE: devices are intended for setting supply voltage intervals within the limits of the monitored ranges of voltage deviations. They also define probability of the given voltage value falling into the proper voltage interval at power supply device intput and output. Deflection coefficients for consumed by light sources energy are calculated for each voltage interval. Energy deflection coefficients are calculated for power supply unit input and output; power intensity of power supply unit is defined as a ratio between energy deflection coefficient at input and energy deflection coefficient at power supply unit output. ^ EFFECT: consideration of light sources characteristics dependency on supply voltage. ^ 2 dwg
