Abstract
A lamp heater and a drying apparatus including the same, the lamp heater including a plurality of three-phase power source lamps, a dummy load, the dummy load being configured to maintain a phase balance of the three-phase power source lamps, and a controller, the controller controlling the three-phase power source lamps and the dummy load depending on a lighting condition of the three-phase power source lamps.
Claims17
A lamp heater, comprising:
- a three-phase power source lamp, the three-phase power source lamp including a first lamp between a first power source line and a second power source line, a second lamp between the second power source line and a third power source line, and a third lamp between the first power source line and the third power source line;
- a dummy load configured to maintain a phase balance of the three-phase power source lamp, the dummy load including a first load between the first power source line and the second power source line, a second load between the second power source line and the third power source line, and a third load between the first power source line and the third power source line;
- and
- a controller controlling the three-phase power source lamp and the dummy load depending on a lighting condition of the three-phase power source lamp, wherein the first load includes the same load as the first lamp, the second load includes the same load as the second lamp, and the third load includes the same load as the third lamp.
