20090091269 | High Frequency Pulsed Supply For Discharge Lamps - The HIGH FREQUENCY PULSED SUPPLY FOR DISCHARGE LAMPS describes electronic converters for discharge lamps with high frequency pulsed current stabilization. A voltage inverter is employed either in a Full-Bridge configuration using peak current control or in a Half-Bridge configuration with a capacitive element. These converters allow the luminous intensity of the lamp to vary (dimming), as well as the frequency of the pulses over a wide frequency range, avoiding acoustic resonance to appear; they also allow a low frequency power variation, aiming to improve the color rendering index and correlated color temperature properties of the light emitted by certain types of discharge lamps, such as the high pressure sodium lamps. The converters present a significant reduction in the volume of the power circuit due to the removal of the magnetic element, being even more attractive as the power of the lamp increases. | 04-09-2009 |
