Disclosed is an electronic ballast for a fluorescent lamp having a high capacitance capable of turning on lamps of different capacitances (36W, 18W), or selectively two lamps of the same capacitance or one lamp, using one circuit, by replacing a lamp driving unit with an integrated circuit (IC). The electronic ballast comprises a power separator for separating a DC power into a lamp power and a circuit driving power, a constant-voltage unit for making the circuit driving power a constant voltage, a switching signal generator that is driven by the power supplied from the constant-voltage unit, for generating a pulse width modulation (PWM) signal corresponding to a capacitance of a lamp connected thereto to lamps having different capacitance or a plurality of lamps, a first transformer for inducing the signal outputted from the switching signal generator to the secondary side, first and second field effect transistors for performing a switching operation corresponding to the output signal from the secondary side of the first transformer in order to generate a high voltage for turning on a fluorescent lamp, and a plurality of bulb for turning on the lamp (CF lamp) using the high voltage generated by the second and third transformers.

Electronic ballast for fluorescent lamp

A ballast socket for compact fluorescent lamp is disclosed. The ballast socket includes: a case having an upper case, which has a receiving space for receiving a lamp and a connection terminal connected with the lamp at a side of the receiving space, and a lower case, which has a through hole at a lower center of the upper case; a controller mounted inside the case for controlling lighting of the lamp; pins for connecting PCB and the connection terminal; and a printed circuit board on which various circuit components are mounted. The ballast socket looks similar to an incandescent lamp socket in outward form, but the compact fluorescent lamp, which does not have ballast, is used in the ballast socket. Therefore, the ballast socket prevents waste of resources and environmental pollution by saving electricity, and improves productivity of the lamp by manufacturing the lamp not adhering ballast thereon.
