What brand of ballast is good?
1, ABB ballast
ABB group (Asi Braun Bofari) was founded by Sweden in 1988. ASEA？ Company and Swiss BBC? Brown? Boveri Company is an electrical engineering group with business all over the world. ABB is a global leading company in the field of power and automation technology, and is committed to providing solutions for customers in the industrial and power industries, helping customers improve their performance and reduce adverse environmental impacts. ABB Group's business covers more than 65,438+000 countries and has 65,438+007,000 employees. Serving customers in more than 100 countries around the world.
ABB ballast is characterized by energy saving. The electronic ballast of fluorescent EEFL ballast lamp mostly uses the frequency of 20 ~ 60 kHz to supply power to the lamp tube, which improves the luminous efficiency of the lamp tube by about 10% compared with the power frequency (calculated by the 4-foot-long lamp tube), and its own power consumption is low, which reduces the total input power of the lamp by about 20% and has better energy-saving effect.
More than half of ABB Group's turnover comes from the European market; Nearly a quarter come from Asia, the Middle East and Africa; More than one-fifth come from North and South American markets.
2.IR international ballast
Is IR international? Short for Rectifier (International Rectifier Company). Founded in 1947, IR Company is a semiconductor company with a long history in the world. The company was named after the production of rectifiers, and gradually became famous in the world. At present, it is the most important power semiconductor device company in the world. The company's current annual sales are $600-700 million.
The characteristics of IR international ballast: it can eliminate stroboscopic and make the light more stable. Is beneficial to improving visual resolution and efficacy; Reduce the visual fatigue of continuous operation, which is beneficial to protect eyesight.
3. Half-meter control ballast
Miquelao? International? GmbH, founded by Dr. FritzMartin on 195 1, is a leading international semiconductor device manufacturer. Headquartered in Nuremberg, Germany, Semicon has more than 3,000 employees worldwide and is a financially independent family business. Semicon has 37 subsidiaries around the world, production bases in Germany, Brazil, China, France, India, Italy, South Korea, Slovakia, South Africa and the United States, and eight solution centers around the world (located in China, the United States, France, South Korea, Brazil, South Africa, India and Australia), which can provide customers with fast and comprehensive services.
The characteristics of the half-meter controllable ballast are:? The starting point is more reliable. After the lamp tube is preheated, it is successfully started at one time, avoiding multiple starts. You can dim the lights. For places that need dimming, such as places that used incandescent lamps or tungsten halogen lamps, replacing them with high-efficiency fluorescent lamps with dimmable electronic ballasts can achieve a wide range of dimming of 2%~ 100%.
4. Xiquan ballast
Xi 'an Institute of Power Electronics Technology? Originally under the Ministry of Machinery Industry, it was established in 1999. It is a technical research institution in the field of power electronics industry in China, a national society and association, an important national core periodical and an international IEC? T42 Special Committee and Secretariat of National Power Electronics Standardization Technical Committee are located, and they are subordinate units of National Power Electronics Product Quality Supervision and Inspection Center. It is the only professional research institute engaged in the research of power semiconductor device technology and converter technology in China.
Characteristics of ballast in Xiquan Institute: stable input power and output luminous flux: high-quality products have good voltage stabilization performance, which can keep the power of light source constant and stabilize the illumination under the condition of large difference between power supply and voltage, which is conducive to energy saving.
Working principle of inductive ballast
When 220 volts is applied to the closed circuit of the switch? When a 50HZ AC power supply is used, current flows through the ballast, and the filament upconverter heats the filament (the upconverter is turned off at first, because an AC voltage above 190V is applied, the gas in the beating bubbles in the upconverter is discharged by arc, so that the bimetal is heated and deformed, and the two electrodes are close together to form a channel to heat the filament). When the two electrodes of the starter are close together, the bimetal is cooled because there is no arc discharge. The poles are separated. Because the inductive ballast is inductive, when the circuit is suddenly interrupted, a pulse voltage of 600V- 1500V with a duration of about 1ms will be generated at both ends of the lamp. The exact voltage value depends on the type of lamp. In the case of discharge, the voltage across the lamp will drop immediately. At this time, on the one hand, the ballast will limit the lamp current, on the other hand, it will produce 55 between the power supply voltage and the working current of the lamp. -65。 Phase difference, so as to maintain the secondary starting voltage of the lamp and make the lamp work more stably.
Because of its simple structure, inductive ballast, as the first ballast of fluorescent lamps, has a relatively large market share. Because of its low power factor, poor low-voltage starting performance, high energy consumption, stroboscopic and many other shortcomings, its market has gradually been replaced by electronic ballasts. Energy loss of the inductive ballast: 40W (lamp power)+10W (heating loss of the inductive ballast itself) is equal to the total power consumption of the whole set of lamps.
The most important thing for us to buy a ballast is the experience of this ballast. The reason why so many people don't choose online shopping is because we can't really experience this kind of ballast when shopping online, but buying on the spot will make people feel much more practical. Tuba Rabbit wrote this article today, hoping to help you experience this ballast brand and its quality, and let you know more about your own needs and what you really need. I hope the article will be useful to you.
The above is about what brand of ballast is good, I hope it will help everyone!
