Claims (1)
【実用新案登録請求の範囲】[Scope of utility model registration request] トランジスタ８のベースにサーミスタ１３を直 列に接続し、放電灯のランプ電流を検知して電流 が流れているときにはトランジスタ８をオンし、 電流が流れていないときにはトランジスタ８をオ フしてなる放電灯用トランジスタ式インバータ。 A thermistor 13 is connected in series to the base of the transistor 8, detects the lamp current of the discharge lamp, and turns on the transistor 8 when the current is flowing. A transistor type inverter for a discharge lamp that turns off the transistor 8 when no current is flowing.
