Title: Discharge lamp lighting device
Inventor: TODOROKI TSUYOSHI
IPC: H05B41/36
Filed: 1989-02-16
Abstract: PURPOSE:To accelerate the rising of the generated light quantity and obtain the desired quantity of light at the stable discharge state by gradually reducing the discharging current in sequence, and making the change width from the lighting start time to the preset time a different value from that thereafter. CONSTITUTION:A control means 6 judges whether dielectric breakdown occurs in a discharge lamp 5 or not based on the voltage value VR at the connection point between capacitors C1 and C2 or the voltage value V of a resistor R, and it sets the frequency of the signal S1 to a low initial value, e.g. 4kHz, if dielectric breakdown occurs. When the voltage applied to an LC serial circuit 4 is kept constant and its frequency is changed, the discharging current flowing through the discharge light 5 is changed, when the frequency is increased, the current flowing through the discharge lamp 5 is decreased. The AC voltage with the frequency 4kHz is applied to feed a large current immediately after dielectric breakdown, then the frequency is gradually increased until 6kHz is attained, and the frequency is sharply increased thereafter. The generated light quantity quickly rises, and the desired quantity of light can be obtained at the stable discharge state.
