The driving frequency of inverter is 45KHz～55KHz, and drive current is 20mA～40mA.
Cold cathode arc grille lamp provided by the invention, beneficial effect is as follows: 1, existing conventional fluorescent fluorescent tube is replaced with cathode fluorescent tube, adopt inverter to drive under high frequency, no stroboscopic, scintillation have effectively been protected eyesight; Can start at normal temperatures, need not carry out preheating, toggle speed is fast, anti-frequent switch, the number of starts is greater than 1,000,000 times, and nearly 100% UV transfers visible light to, and light decay is little, no ultraviolet radiation, do not hinder eye, almost uniform illumination is provided, be fit to long-time illumination and use; Reach service life more than 50,000 hours.
The present invention is as shown in table 1 with the performance indications that T82 * the 20W arc grille lamp is compared with existing civil area: table 1 the present invention and existing civil area are with the every performance indications of T82 * 20W arc grille lamp relatively
From last table, find out; of the present inventionly improve more than 40% than T82 * 20W arc grille lamp light efficiency; colour rendering index is excellent, and start-up time is short, long service life; mercury content is very low in the fluorescent tube; meet international environmental protection RoHS standard, be convenient to recycling, can significantly reduce problem of environmental pollution; protected earth ecology, its every index all is better than T82 * 20W arc grille lamp.
| Power consumption (W) | Luminous flux (lm) | Colour rendering index (Ra) | Service life (Hs) | Start-up time | Mercury content (mg) | |
| | ??39～??41 | ??890～1000 | ??75～80 | ??8000 | 1 second | ??20mg |
| The present invention | ??24～??25 | ??1400～??1500 | ??80～85 | ??≥50000 | 100 milliseconds | ??＜3.5mg |
2, the control chip of inverter adopts intelligent IC half-bridge driven control chip; the parameter that self adaptation ZVT (ZVS) mechanism that adopts the control circuit of this IC chip detects in the lamp works process changes; can turn-off output circuit according to detected abnormal condition of lamp tube situation, defencive function is strong, safe and reliable.
3, owing to adopt the cathode fluorescent tube of external diameter greater than 4.0mm, arc grille lamp with the cathode fluorescent tube of the existing employing external diameter same length that is 4.0mm is compared, can be higher bear causes damaged external force, and tube voltage reduces by 20% on year-on-year basis, and is safer; Power of lamp tube promotes more than 100%, and luminous flux promotes more than 100%, is suitable for the occasion of various illumination requirement, is particularly useful for public place illuminations such as office, market, bank.
