Embodiment Construction
[0041] Such as figure 2 As shown, a discharge lamp 1 of the present invention includes: a lamp tube 10, electrodes 11, 12 are respectively provided at the inner ends of the lamp tube 10, and filled with fillers (not shown); and At least one side of the electrode 11 or 12 inside 10 is provided with an electric heating member 13. Wherein, the lamp tube 10 is a glass tube whose two ends are fusion-sealed, and the filler inside can be at least one light-emitting gas or mixed gas. The electrodes 11 and 12 and the wires 14 and 15 of the electrical component 13 respectively lead out the ends of the lamp tube 10 to form circuit contacts 16 and 17. In the discharge lamp 1 constructed in this way, the electrodes 11 and 12 at both ends are used for triggering and normal lighting when lighting, and the electric heating member 13 is used for preheating and emitting electrons in the initial stage of lighting, so as to use the emitted electrons to heat adjacent Electrodes 11, 12, and the la...
