Purpose - To measure the ability to sustain high frequency vibration
Criteria - Change in glass material, sealing method, or any major modification
Testing Procedures
Step 1 -
Leave the test lamp for 2 hrs at 25±2°C, 35~85% R.H. windless environment and then measure the lamp voltage, starting voltage, brightness and chromaticity.
Step 2 -
Full amplitude: 1.5mm, 10-55-10 Hz/min. in direction X, Y, Z respectively for 2 hours.
Step 3 -
Place the lamp for 2 hrs in 25±2°C windless environment and then measure electrical characteristics, brightness, chromaticity and starting voltage again.
Acceptance Criteria
Lamp is able to discharge.
Lamp is not broken, or damaged.
Xenon
