Title: Method of inspecting fluorescent lamp
Inventor: ARAI YOJI
IPC: H01J9/42
Filed: 1990-02-02
Abstract: PURPOSE:To perform detection with high precision by obtaining the specific wavelength and the specific wavelength range of the mercury spectrum, comparing the obtained light intensity ratio with a preset value, and judging the quality based on the difference. CONSTITUTION:The power of a high-frequency power source 2 is applied to a fluorescent lamp 1 to generate a glow discharge in the lamp 1. If impure gas is mixed, the emission spectrum distribution peculiar to the phosphor is changed. Signals photoelectrically transferred by detectors 3a, 3b are amplified by amplifiers 6a, 6b and inputted to an amplifier 7. The inputted signal is divided by the amplifier 7, and the resultant signal is amplified. Band-pass-filters 4, 8 are fitted on the window side of the detectors 3a, 3b, and the preset wavelength of the mercury spectrum is set at the center. The intensity ratio between mercury spectra with the wavelength 405 or 436nm and 460-520nm is determined by the amplifier 7, it is compared with the reference value of a reference generator 8 by a comparison amplifier 9, if there is a lamp 1 exceeding the reference value, a signal is sent to an extracting device as a defective product. High- precision detection can be performed.
