| titleOfInvention | Rare gas fluorescent lamp lighting device |
| abstract | In the case of burst dimming, the uniformity of the rare gas fluorescent lamp axial luminance distribution is maintained, and the flicker is suppressed.n n n When the brightness control signal is turned on, the AC conversion circuit 2a converts the DC voltage from the DC power supply 2b into a high frequency voltage and applies the rare gas fluorescent lamp 1 to light it. Stop the output of voltage. The lamp 1 is controlled by controlling the time ratio between the on period and the off period. When the lamp 1 is turned on, an inversion current flows from the AC conversion circuit section 2a to the DC power supply 2b. The interruption circuit 4 blocks the inversion current when the inversion current control signal output from the control circuit 3 is off. By preventing the inversion current, the electric charge accumulated in the lamp by the discharge can be maintained, and the delay of light emission can be shortened. For this reason, deterioration of the uniformity of luminance distribution, flicker of brightness, etc. can be improved. |
