METAL-HALOGEN LAMP Russian patent published in 1995 - IPC

FIELD: lighting engineering. SUBSTANCE: burner of optically transparent material with hermetically sealed electrodes is filled with inert gas, halogenides of alkali metals in the amount of 0.27-1.9 μmole/cm³, additives to provide burner with halogenides of emitting metals in the amount of 0.65-8.48 μmole/cm³. Ratio of pressure in kPa to amount of additives in μmole/cm³ is within 29.0-205.0. Titanium in the amount of 2.0-25.0 μmole/cm³ is additionally injected into burner. Pressure of inert gas is kept 26.6-200.0 kPa. EFFECT: enhanced operational efficiency, improved stability of characteristics. 1 dwg, 1 tbl
