There are two main types of ballasts for fluorescent lamp ballast gas discharge lamps:
(1) Inductive ballasts, including common type and energy-saving type; also divided into ordinary magnetic ballasts and HID magnetic ballasts.
(2) Electronic ballasts entered the market in the late 1970s, and China began to develop and produce in the mid-1980s. This type of ballast product also has different harmonic content and energy consumption.
There are no clear boundaries between ordinary and energy-efficient ballasts, and it is not convenient to promote applications. The EU's energy efficiency rating standards for straight tube fluorescent lamps have specific data regulations, and different levels of products specify power limits for reference. Table 1 lists the division of energy efficiency ratings for T8 fluorescent lamp ballasts by the CELMA organization in the European Union.
The energy efficiency levels specified in Table 1 shall be tested in accordance with the European standard EN 50294 and may be given a corresponding rating.
The C-class and D-class magnetic ballasts that the EU has banned are the inductive ballasts that should not be used in the newly issued national standard "Architectural Lighting Design Standards" (GB50034-2004). The standard also stipulates that straight tube fluorescent lamps should use electronic ballasts or energy-saving magnetic ballasts. The former is equivalent to the European standard A2 and A3 products; the latter is equivalent to the B1 and B2 products. From the data of the “Standard Training Lecture†prepared by the standard compilation group, it can be seen that in the development of the “Lighting Power Density (LPD)†standard, the system power of the electronic ballast is equivalent to the A2 level, and the energy-saving magnetic ballast The system power is slightly higher than B1, but lower than B2.
