SU636715A1 - Composition for filling incandescent lamps - Google Patents

Description

I

The invention relates to light sources, in part, to the filling of a Gaussian-type incandescent lamps.

Known pampas with a krypton deposition for a voltage above 36 V are known, in which the following nitrogen-krypton mixture is used for filling.

N2 1O - 16%

Kg 90 - 84% O.

Of the known mixtures used for filling krypton filament lamps, the one closest to the invention is a mixture

M 10%

Kt "90%,

as it allows to obtain the maximum light output at an acceptable voltage of the breakdown.

This mixture has a high cost, which makes it difficult to use it widely for glow plugs, since the light output decreases with an increase in the percentage of nitrogen, and the intensity of the sample decreases with decreasing reduction.

The aim of the invention is to increase the effectiveness of the composition.

To achieve this goal, argon is additionally added to the lime mixture, which contains nitrogen and krypton, and the content of all the above ingredients should be in the following ratios (% by volume):

N28-9

Ati 15 - 20

CG 77 - 71.

FIG. Figure 1 shows the dependence of the decrease in luminous flux (luminous efficiency) on the percentage of argon in krypton, with N 10%; in fig. 2 - change in luminous flux (luminous efficiency) from the percentage of nitrogen in krypton — for one 1OO watt lamp; FIG. 3 shows the dependence of the breakdown voltage on the nitrogen content of krypton; in fig. 4 The dependence of the breakdown voltage on the addition of argon krypton for batches of 1 VW lamps.

The choice of the mixture was made, and the mixture itself was tested for 100 W of pampas, 20 lamps each

in each batch. The results are presented in the b table.

As can be seen from FIGS. 1-4 and table, the addition to argon krypton is associated with light and voltage. The rational addition of argrina is in the range from 15 to 20%, and with its further increase the light output decreases. The composition has a higher cost per unit due to a decrease in the percentage of the cryton. The technology of making lamps with the proposed composition does not change as compared with the previously known composition used. Lamp life meets the requirements of GOST, Claims of the invention. The composition for filling of lamps with an incandescent light of no more than 36 V, containing -IIIIIII-IiOO% Ar ioo% Ki la to g 10/90% Ar wide nitrogen and krypton, is excellent and so that, in order to increase its efficiency, argon was additionally introduced into it with the following ratio of ingredients in% by volume: My 8-9, A g - 15-20, K p 77-71.
