Title: Lighting device for discharge lamp
Inventor: TSUJI KOJI
IPC: H05B41/24
Filed: 1990-03-09
Abstract: PURPOSE:To improve switching control without enlarging a transformer by providing a first lighting means for lighting a discharge lamp through first frequency during the initial period of lighting, and a second lighting means which when a predetermined lighting voltage is reached changes the first frequency to second frequency higher than the first frequency and lights the lamp. CONSTITUTION:The lighting voltage of a lamp 1 is detected from a voltage detecting circuit 9. This detection signal is input to an operation amplifier OP1 via a resistance R1. A reference value is set at the operation amplifier OP1. The output of the operation amplifier OP1 is connected to a photocoupler PC. The photocoupler PC is electrically connected to an IC. While the voltage of the lamp 1 is low after lighting of the lamp 1 is started, the output of the operation amplifier OP1 is L and the photocoupler PC does not work and first frequency is transmitted as a signal from the IC1 to a drive circuit 11. When the lighting voltage is raised and the output of the operation amplifier OP1 is converted to H, a signal is transmitted to the IC1 via the photocoupler PC and second frequency is transmitted as a signal to the drive circuit 11.

An evaluated value calculation part 322 finds two-dimensional dispersion of the fragmentized rectangular blank areas as an evaluated value of the layout. A decision part 330 compares the evaluated value with a predetermined specific threshold value and when the evaluated value is not larger than the threshold value, the layout is displayed as a proper layout at a display part 340. When the evaluated value is less than the threshold value, it is indicated that the blocks should be re-laid out.
