Outline of Final Research Achievements |
For large-scale illumination that is necessary for emergencies, brightness and light color are extremely important. However, the heat loss increases with increasing the current in order to obtain a high intensity. Therefore, it is required that the radiation power increases at the low input power. It is necessary to control the temperature distribution with controlling the current and radius. In this study, the water-cooled vortex type of wall-stabilized high intensity arc lump for improvement of lamp efficiency and color rendering was developed with experiment and using electromagnetic thermal fluid simulation. As a result, the radiation power increased when the wall diameter decreased or as the input power increased.
