Judging Conditions

 

After reliability testing, the characteristics of testing lamps must be met the following requirements:

1. Startup voltage: No over 10% of initial value.
2. Luminance: At least 50% of initial value.
3. No mechanical or physical damage (e.g. nickel guide pin broken)
4. No visible distortion, colorchanging etc.
5. No lamp can't light up.
6. The luminance should be up to 95% of it stability, after power on 3 minutes.
7. No darken, color changing in appearance, or unnormal lighting (flicking smacking etc)
   

Testing Conditions:

• Impact testing:

Pulse wave of 30G, llm/sec2 should be applied three times each in X,Y,Z directions.The lamp should be held on the testing fixture.

• Vibration test:

Acceleration 19.6m/sec2,frequency 20-500-20Hz be applied in 3 minutes each time, and each In X,Y,Z directions for lhr. Be careful to prevent resonant point.

• Terminal wire intensity test:

Tube axial load: lkg
Time:5 sec.

• Heat-cycle test:

  Operating 10 cycles as following condition

  
• High-temperature & humidity storage test:

  Temperature:70±2°C
  Humidity: 90±5%R.H
  Time: 500hrs
  The lamps should be preserved at room temperature for 2 hrs before doing function testing.

• High temperature storage test:

  Temperature: 70±2O°C (Dry)
  Time: 1000hrs
  The lamps should be preserved at room temperature for 2 hrs before doing function testing.

• Low-temperature storage test:

  Temperature: -30°C ±2O°C
  Time: 1000hrs
  The lamps should be preserved at room temperature for 2 hrs before doing function testing.
  

• High-temperature & humidity operating test

Temperature: 40±°C

Humidity: 90%R.H

Time: 5mA

Current: 5mA


• Sealed test:
  

Sampling 40pcs dipped in the boiling water(>95°C) for 10 sec, then dipped in 4°C water for 10 sec. Doing cycle 3 times. All samples should be passed, if there is one fail, do the Next test again.


• Snaking test:
  

  Temperature: 50±2°C
  Time: 24hrs
  Current:5mA
  The lamps should be preserved at >0°C ±2 temperature for 2 hrs before doing function
  testing.
  

• Low-temperature operation test:

Temperature:0±1°C Time: 5mA The lamps should be preserved at room temperature for 2 hrs before doing function testing. testing.

Lamp Quality Control

In order to control the lamp's quality, according to CNS 2779 Z4006 table II -A ~single sampling plans of normal inspection to do the quality control.

1. Bad quality: Snaking, flicker, crack (No external force)
2. Light bad quality: Fluorescent coating cracked & peeled off
   

Remark:

1. Hg sticked on inner wall of tube is normal.
   
2. Light black color of two end-sides of glass tube is normal.
   
3. Fluorescent coating peeled off in 15mm from two end-sides is not counted.
