LAMP CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2004281171
Kind Code:
A
Abstract:
To realize miniaturization of a lamp control system including a lamp drive circuit consisting of semiconductor elements, and improve reliability of the lamp drive circuit.
This lamp control system is constituted by incorporating a constant current circuit including elements composed of the lamp 3 such as an incandescent lamp and a discharge lamp or the like, and a wide gap semiconductor (with a band gap kinetic energy of 3.0 eV or more, for example, a GaN series semiconductor or the like), or the lamp drive circuit 2 such as an inverter circuit or the like, and the power supply part 1.
