Abstract

PURPOSE: To decide the impure gas mixture defect of a discharge lamp objectively by causing glow discharge in a discharge lamp and measuring the infrared-ray intensity of luminescence dependent upon this discharge and deciding a discharge lamp, which has a high infrared-ray intensity, as impure gas mixture defective.
CONSTITUTION: Glow discharge is caused in a discharge lamp, and luminescence dependent upon this discharge is inputted to infrared-ray detection element 4 through condenser lens 2 and infrared-ray transmission filter 3. After amplified by amplifier 5, the electric output of detection element 4 has the level indicated on indicator 6. In case that impure gas such as nitrogen, oxygen, carbon monoxide and aqueous vapour is mixed in the discharge lamp, indicator 6 indicates a high value due to a high infrared-ray intensity, so that the impure gas mixture defect of the discharge lamp can be decided.
