Abstract

A curling iron provided with an infrared radiation source within a hollow barrel for radiating infrared radiation within a predetermined band. The barrel is substantially transparent to radiation within the band emitted by the source. The curling iron is provided with a hair clip for retaining hair wound about the barrel, the clip also being substantially transparent to this infrared band. A fan is provided for blowing cooling air past the infrared source and through the barrel, the tip of the barrel being sufficiently perforated to pass this cooling air. The curling iron is further provided with a circuit for energizing the infrared source in a predetermined cyclical manner in order to maintain the temperature of the barrel within a predetermined range. A temperature sensor is further provided to sense the temperature of the barrel in order to activate the control circuit accordingly.
