one. The characteristics of high-power energy-saving lamps.
1. The rare earth trichromatic phosphor is used, and the luminous efficiency is ≥60 lm/W.
2. High color rendering, color rendering index ≥ 80Ra.
3. The starting voltage range is wide, and it can be started normally at 150V-265V without stroboscopic glare.
4. Work without noise.
5. Rich in light color, a variety of color temperatures can be selected.
6. Low calorific value, effectively reducing the ambient temperature.
two. Classification of high-power energy-saving lamps. From the structure of the lamp body: integrated high-power energy-saving lamps and split-type high-power energy-saving lamps.
1. Integrated high-power energy-saving lamp: The electronic ballast is installed in the plastic part of the lamp cap and integrated with the lamp tube. After being installed as a lamp, the integrated energy-saving lamp does not pass the professional tools. It is impossible to separate the electronic ballast from the lamp tube by hand.
2. Split-type high-power energy-saving lamps: The electronic ballasts and lamps of the control lamps are separated separately. The input end of the electronic ballast is connected to the power supply, and the output end is connected to the lamp tube through two wires connected to the lamp holder. After the lamp is damaged, the electronic ballast or lamp can be replaced separately.
three. Integrated high-power energy-saving lamps and split-type high-power energy-saving lamps are excellent and disadvantages:
four. Split-type high-power energy-saving lamps greatly extend the life.
1. Keep away from heat. Electronic ballasts contain semiconductor diodes, triodes; electrolytic capacitors, electrodeless capacitors; magnetic rings, magnetic cores and other electronic components. As the ambient temperature increases, the performance of these electronic components may be deviated, such as the amplification factor of the triode increases, the withstand voltage of the capacitor decreases, and the leakage current increases. In particular, electrolytic capacitors, the electrolyte in the body is easy to dry at high temperatures. Some foreign experts have proposed in the paper: electrolytic capacitors of the same quality, under the same conditions, the ambient temperature rises by 10 ° C, and the electrolysis life is half short. It can be seen that the effect of high temperature on electronic ballasts is fatal.
2. Can effectively set the protection circuit. Due to the influence of space and temperature, reliable anti-surge voltage protection circuit can be set in electronic ballast; harmonic and electromagnetic interference suppression circuit; overcurrent and overvoltage protection circuit; no-load protection circuit; over-temperature protection Circuit; broken tube of the lamp; leakage protection circuit. The electronic ballast temperature of the integrated high-power energy-saving lamp is not high when the lamp is turned on. With the lamp point for a period of time, the temperature of the electronic ballast can reach 90-100 degrees, the temperature difference is large, and the volume of the plastic parts of the lamp cap is large. Restriction, it is impossible to effectively set up a perfect protection circuit, usually the ballast is burned together when the lamp is terminated or abnormal.
It can be seen from the above that the integrated high-power energy-saving lamp is simple and convenient to install, and the cost is slightly lower. It is excellent in cost performance when the ambient temperature is not high, but it will be much shorter in high temperature and closed lamps. Split-type high-power energy-saving lamps are slightly more complicated when they are first installed. The cost is slightly higher, but she overcomes the shortcomings of the integrated high-power energy-saving lamp, and greatly reduces the re-purchase cost and installation labor cost in the later use. In the long run, the energy saving effect is absolutely worthwhile.
Fives. The key to greatly extending the life of the split-type high-power energy-saving lamps is the high reliability of the electronic ballast and the perfect protection circuit, otherwise everything is meaningless.
