Abstract:
A starting apparatus for a high-pressure discharge lamp provided with an auxiliary starting electrode, has a series resonant circuit for the purpose of generating the starting voltage for the high-pressure discharge lamp. The resonant inductance of the series resonant circuit includes the primary winding of a transformer, whose secondary winding is provided for the purpose of applying the starting voltage to the auxiliary starting electrode (Z) of the high-pressure discharge lamp. The invention also relates to a high-pressure discharge lamp, in particular to a vehicle headlight lamp, having such a starting apparatus arranged in the lamp base.
Abstract:
In order to improve the starting of a dielectric barrier discharge lamp it is proposed to provide elements for igniting an auxiliary discharge inside the exhaust tube (5) of the lamp.
Abstract:
A high PAR maintenance rate type high pressure sodium lamp with an auxiliary starting switch is provided with an external glass tube and a discharge tube which is arranged at the center in the external glass tube and coaxial with the external glass tube. The surface of the discharge tube is provided with a metal lead. The left and right ends of an external glass shell are provided with pressure sealing plates which are fused and sealed through high temperature. The pressure sealing plates are internally provided with conductive sheets. One end of the discharge tube is connected with the conductive sheet of the left end through a left internal conductive support, and the other end is connected with the conductive sheet of the right end through an auxiliary starting switch component. According to the high pressure sodium lamp, the high pressure sodium lamp can be quickly lit up through a temperature controlled switch so that the high pressure sodium lamp has the advantages of being great in starting performance, great in lighting effect, high in stability, long in the service life, great in high temperature resistance and high pressure resistance and safe and reliable and is not liable to crack.
