What are the types of fluorescent lamps?
Straight tube fluorescent lamp. This fluorescent lamp belongs to double end fluorescent lamp. The common nominal power is 4W, 6W,8W, 12W, 15W, 20W, 30W, 36W, 40W, 65W, 80W, 85W and 125W. by T5 T8, T10 diameter, G5 G13.T5, T12. lamp, >30 color index, good color, lighting effects, ideal for environmental goods and rich colors of the decline of small, long service life, the average life expectancy of 10000 hours. Suitable for clothing, department stores, supermarkets, food, fruit, and other colorful pictures, display window use.T8 color, brightness, energy saving, life is good, suitable for hotels, offices, shops, hospitals, libraries and family but requires simple color high brightness occasions.In order to facilitate installation, cost reduction and safety, many ballasts for straight fluorescent lamps are mounted in brackets to form self ballasted fluorescent lamps
Straight tube type fluorescent lamp according to the diameter is divided into: T12, T10, T8, T6, T5, T4, T3 and other specifications. The specification "T+" combination, said digital diameter mm value. Its meaning: a T=1/8 inch, one inch is 25.4mm; the number of digital T. Such as T12=25.4mm*1/8*12=38mm.
The single side compact fluorescent lamp. The lamp, fluorescent lamp ballast and the lamp tightly integrated (ballast inside the base), in addition to destruction, to put the demolition, it was known as the "compact" fluorescent lamp. Because no additional ballast, the driving circuit in the ballast. The fluorescent lamp is self ballasted fluorescent lamp and fluorescent lamp. The lamp start by E27 lamp directly with the power supply network connection, can directly replace incandescent lamps.
Color fluorescent lamp. Common nominal power of 20W, 30W, 40W., T5, T4 in diameter, luminous flux G5, G13. color fluorescent lamp with T8. lamp is low, suitable for shop windows, advertisements or similar places decoration and color display. (3) the annular fluorescent lamp. In addition to shape, no more the big difference between the annular fluorescent lamp and tube fluorescent lamp. Common nominal power of 22W, 32W, 40W., G10q.. Lamp mainly for ceiling lamps, chandeliers and other supporting source, for family, shopping malls and other lighting.
Relationship between the diameter of fluorescent lamp tube and its electrical parameters:1, fluorescent tube, the smaller the diameter, the higher the light efficiency, the better power-saving effect2. The smaller the diameter of the fluorescent tube, the higher the ignition voltage of the glow lamp, the higher the technical performance requirements of the ballastThe diameter is larger than T8 (T8) fluorescent lamp starter ignition voltage is low. Compared with 220V, 50Hz AC, with starting ignition voltage less than 1/2 power supply voltage law. Can use inductive ballast, for starting and lighting operation.
