Modeling and analysis of a novel igniter for HID lamps

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 the electronic properties; (2) Based on the proposed model, theoretical analysis and design consideration are also given; (3) A prototype for 575 W HID lamp has been built. The proposed theory and approaches have been verified by the results of the experiments and computer simulation given in this paper. The experimental results show that the volume and weight of the prototype has reduced by at least 80% than of the magnetic igniter.
