Abstract

Disclosed is a car-used highstrength discharge lamp with lamp base, comprising electrical arc tube full of ionogenic substance, lamp base, the sealed first and second neck body which from an angle of 180deg.C separately on two ends of electrical arc tube, and cover casing enclosing electrical arc tube and neck body. There are two electrodes in electrical arc tube, the two electrodes are connected to wire with one electrode couple on extension line of lamp base axial line and another deviating lamp base axial line. The invention has two groups of electrodes in one electrical arc tube, by replacing electrode couple to replace the position of electrical arc (light source), to adjust shape and distribution of illuminance outgoing beams, realizing the function of switching over function of distance light and passing light. Its function is same to common tow-filament tungsten halogen lamp (9007) and increase illumination function by directly being replaced.

Description

technical field [0001] The invention belongs to a high-intensity discharge lamp for vehicles with a lamp base. Background technique [0002] A single-ended high-intensity discharge lamp with a lamp cap usually consists of a gas-tight spherical or ellipsoidal gas discharge arc tube made of high-purity quartz glass and filled with ionizable substances. The arc tube contains a pair of electrodes. , The two ends of the arc tube are provided with shrinking and sealed neck parts at an angle of 180 degrees to each other. The two necks support an electrode respectively, and the electrode lead wire passes through the center of the neck. The arc tube can be directly used as a light source. In order to ensure the stability of the arc tube, the arc tube and the neck can be provided with a cover made of quartz material that can absorb ultraviolet rays. The cover is usually airtight, and its two ends are connected to the neck of the arc tube Tighten the connection. The lead wire of the...
