Abstract： |
The invention comprises a high-frequency ballast inductor and glow-starting circuit of the high-voltage sodium lamp. When a high-frequency DC square wave is put to the high-frequency ballast inductor, the glow-starting circuit under the action of the DC square wave can make the high-voltage sodium lamp start by controlling the induction coil of the high-frequency ballast inductor. The high-voltage sodium lamp current detection signal forming circuit can control the glow-starting circuit to make it stop working via the current detection signal produced by the current inductor series connected on the high-voltage sodium lamp. |
