Day-U Light UV SCC Series
Day-U Light UV SCC Series memiliki cara kerja dengan katoda dingin.
Lampu katoda dingin adalah lampu pelepasan gas pijar bertekanan rendah. Pelepasan cahaya menggunakan ion positif untuk membombardir katoda logam dengan kemurnian tinggi untuk menghasilkan elektron sekunder untuk mempertahankan pelepasan.
Arus katoda terutama disumbangkan oleh ion positif, dan arusnya relatif kecil, maka disebut namanya “katoda dingin”.
WATER QUALITY REQUIREMENT
- Maximum operating pressure 0.8MPa (116psi)
- Ambient water temperature 2-40 ° C (36-104 °F)
- Iron <0.3ppm (0.3mg/L)
- Hardness <7gpg (120mg/L)
- Turbidity <1NTU
- UV transmittance >75%
- UV dose ≥ 30ml/cm²
FEATURES
- Compact size
- Low power consumption
- Frequently turn on/off does not affect the life of the lamp.
- With an avarage life span more than 20,000 hours
- UV chamber with great welding process which enables to pass 1.04MPa 100,000 times water hammer test
WORKING PRINCIPLE
The cold cathode lamp is low-pressure glow gas discharge lamp. The glow discharge uses positive ions to bombard a high-purity metal cathode to generate secondary electrons to sustain the discharge . The cathode current is mainly contributed by the positive ions, and the current is relatively small. Hence the name “cold cathode”.
