Embodiment Construction

[0041] Such as figure 2 As shown, a discharge lamp 1 of the present invention includes: a lamp tube 10, electrodes 11 and 12 are respectively arranged at both ends of the lamp tube 10, and filled with fillers (not shown); One side of at least one end electrode 11 or 12 inside 10 is provided with an electric heating member 13 . Wherein, the lamp tube 10 is a glass tube with both ends welded and sealed, and the filling inside it can be at least one gas or mixed gas for lighting. The electrodes 11 , 12 and the wires 14 , 15 of the electrical component 13 are respectively led out from the end of the lamp tube 10 to form circuit contacts 16 , 17 . In the discharge lamp 1 thus constituted, the electrodes 11 and 12 at both ends are used for triggering and starting and normal lighting during 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 lamps. electrode...

Abstract

An indirect preheating start discharge lamp and a device thereof, wherein the discharge lamp comprises a lamp tube with electrodes respectively arranged at the two ends therein and filling material sealed therein; one side of the electrode of at least one end inside the lamp tube is provided with an electric heating component, wherein the electrode and the lead of the electric heating component are respectively led out of the end part of the lamp tube to form a circuit joint, and is also provided with a lighting device with the discharge lamp. At the initial lighting stage of the discharge lamp, the electric heating component in the lamp tube emits electrons to heat adjacent electrode and fills initial electrons in the lamp tube, thereby reducing the trigger starting voltage of the lamp, protecting the electrode, and prolonging service life of the lamp.

Description

technical field [0001] The invention relates to an indirect preheating starting discharge lamp and its device. Background technique [0002] Such as figure 1 Shown is a schematic diagram of the structure of a conventional discharge lamp. The working principle of this kind of discharge lamp 3 is that the light-emitting gas filled in the lamp tube 31 is excited or ionized to emit light by applying a voltage between the electrodes 31 and 32 at both ends of the glass lamp tube 31 . Various fluorescent lamps, cold cathode tubes, and energy-saving lamps currently on the market, also known as energy-saving bulbs or various high-pressure discharge lamps such as mercury lamps, sodium lamps, metal halide lamps, xenon lamps, etc., all belong to discharge lamps with the same working principle. [0003] The main factor at the end of the service life of the existing discharge lamp is the electrode failure, and the main failure form of the electrode is the excessive loss of the cathode m...
