ABSTRACT:
An electronic ballast for one or more F32T8 or F25T8 or F1718 fluorescent lamps has a new design tool for efficient transfer of power to the lamp or the lamps. The design tool is constructed from the ballast DC voltage and the commercially available lamp specifications by the manufacturers or from the American National Standards (ANSI). This design tool is shown below.F×C=K2⁢W2V12-V02R022⁢ ⁢π⁢ ⁢V1where W=Lamp rating in watts,V0=Lamp voltage.V1=Electronic Ballast DC voltage,R0=Lamp Impedance in ohms, (ANSI C78.1-1991).k=Empirical constant=1.5 to 10.0.
