A FLUORESCENT LAMP SYSTEM FOR CONVERTING T8 TYPE FLUORESCENT LAMP TO T5

摘要

A fluorescent lamp system for converting T8 type fluorescent lamp to T5 includes a ballast (2) of T8 type fluorescent lamp, a bracket (20) of a T8 type fluorescent lamp and a T5 type lamp. The T5 type lamp includes a bracket (31) and a fluorescent lamp tube (32) installed in the bracket (31) by corresponding sockets. The first and the second legs (13,14) of the T5 type lamp are electrically connected with the bracket (20) of the T8 type lamp. Two pins (A and C) of the T5 type lamp are electrically connected with the first leg (13) and the second leg (14) by the first inductance L1 and the second inductance L2, respectively. A switch (12) is connected between the first leg (13) and the first inductance L1. The first resonance capacitance C1 is connected between the pin A and a pin D placed in the other side. The second resonance capacitance C2 and a thermistor are parallel connection, and placed between two pins (B and D) of the T5 type lamp placed in the other side.
