Based on the special application of electronic ballast in movie and television industry, a novel electronic igniter for HID lamps has been investigated in this paper. Compared with the traditional magnetic igniter, the circuit has many good performances such as substantially less volume and weight. The main contributions are as the followings: (1) A model of the igniter has been put forward to analyze...
In order to research the characteristic of HID with Medium-High Frequency, it is necessary to make a model for HID to describe the behaviors. Our works focus on the followings: 1) a few of external electrical properties of HID lamps have been measured to represent the V-I characteristic and output power vs. equivalent resistance as well as external voltage vs. equivalent resistance; 2) based on the...
The electric properties of igniter for HID Lamps have been investigated in this paper. The main contributions are as the followings: (1) A few of models of igniter have been put forward to analyize the electric properties; (2) Based on the proposed models, an useful method has been developed; (3) Through the theoretic analyzing, some valuable conclusions for designing this Igniter have been given...
Based on the electric characteristics of HID (high-intensity-discharge) lamps, novel control strategy and implement method for electronic ballasts of HID lamps have been investigated in this paper. The main contributions are as the followings: (1) to ensure to ignite the HID lamps safely, the auto-tracking technique, which can offer proper igniting voltage, has been put forward, (2) to make sure to...
