Description

The invention is applied to the spectro-technical industry and can be widely used in the manufacture of high-pressure gas discharge lamps, in particular lamps with radiating additives. The purpose of the invention is to increase its reliability.

The drawings show the discharge of the lamp, the general view

The main electrodes 2 and 3 and the tube 4, in which the ignition egement is installed, are installed in the flask 1 of the pump, the states of two auxiliary electrodes 5 and 6; The ends of the auxiliary electrodes 5 and b protruding from the tube 4 are located near the main electrodes 2 and 3. Other ends electrodes 5 and 6 are located inside the tube 4 at a distance ensuring the appearance of a glowing discharge at the moment of ignition of the lamgs,

When supplying the power supply, the glowing emitters are lit by the main electrodes and the solid electrodes.

The discharges of the main ones: electrons nt linearize the arc, and the discharge in the discharge gap between the electrodes 5 and 6 O draws current through them. The resistance of the mastic electrodes is sufficiently PI-, rn - axially at the stage of abnormal discharge, so that the current limiting the pg ne the use of high-resistance

After ignition of the arc-like discharge between the main electrodes, the auxiliary bits are shunted

The lamp reliably ignites an external limiting current with a resistance, and, most importantly, under HI, the electrodes do not have a sealant or a yu xi foil, which increases reliability:

lamp and simultaneously eliminate the problem of electrolysis.

If the wire electrodes are coiled, convection currents will circulate through the tube, which eliminates discharge separation when the lamp is lit in a horizontal position.

Claims (1)

Claims of Invention A high-pressure lamp, containing a flask with electrodes installed at opposite ends, 0 filled with inert gas and metal halides and / or mercury, and a tube of refractory glass installed inside the flask along its wall with a burning element located inside it, one ends of which protrude from the tube and are installed near the corresponding electrodes, which means that , in order to increase its reliability, the other ends of the specified element are placed at a distance between themselves, which ensures the occurrence of a glow discharge at the time of ignition.
