ABSTRACT:
An electric smoothing iron is provided which has a soleplate (3) which has a low heat capacity and which is heatable by means of light energy produced by lamps (6), reflectors (7) being provided to reflect the light to the soleplate (3), and the temperature of the soleplate (3) being monitored by means of a sensor, which iron comprises a microprocessor (13) which receives the measurement values from the sensor (12) and compares said measurement values with presettable nominal values of a temperature control device (14), which microprocessor is connected to a power control unit (15) which acts as a half-wave control and operates the lamps separately, in series or in parallel.
