| Specially designed lamp house and transformer for operating different types of spectral lamps that ensures almost immediate striking of the Spectral lamps no sooner they are switched ON and provides a steady light output of high intensity. Transformer encased in a two part aluminium extrusion with insulated plastics side supports for safety having overall dimension of about 230 x 165 x 115mm (LxWxH). Plastic side supports have holes for proper inside ventilation. Provision for mounting a support rod, about 50cm in length, from the top of the transformer casing for holding lamp house makes the apparatus a convenient self-contained assembly. Rod projects more than 40cm above the casing, and provides convenient vertical adjustment in the lamp house position. Lamp house comprises a cylindrical sheet metal enclosure closed at one end with a circular aperture for lamp output. ES Cap type porcelain lamp holder located on inner side of the closed end is used for mounting lamps and provides adequate insulation and safety to the user. It is connected to the transformer through a three-core lead. One side open lamp house is located on top while use to permit uninhibited ventilation to the lamp. It has auto leak transformer operating on AC mains input of 230± 10% volts, 50/60Hz, with fused input protection and power rating of 90W. The transformer has an excessively high leakage reactance to achieve highly drooping current-voltage characteristics, making the secondary output automatically drop from about 470V at no load, regulating the current to 0.9A at the desired voltage to obtain full luminous output from the spectral lamps. |
