Hand held skin treatment device

摘要

A hand held, home use, device for treatment of skin, comprising: a housing exhibiting an opening therein and forming an air cavity when the opening is placed in contact with the skin; an incandescent type bulb secured within the housing and arranged to irradiate the skin with infra-red radiation and heat air within the formed air cavity, the incandescent type bulb exhibiting a filament; and a control and driving circuitry in electrical communication with the incandescent type bulb and operative to output a train of pulses exhibiting an on time when current is driven through the filament and an off time when current is not driven through the filament, the off time greater than or equal to the on time, the off time being of a duration such that the infra-red radiation irradiating the skin falls, during the off time, to no less than 25% of its maximum value.

1. A hand held device for treatment of skin, the device comprising:
a housing exhibiting an opening therein and forming an air cavity enclosing a volume of air when said opening is placed in contact with the skin; an incandescent type bulb exhibiting a filament, said incandescent bulb secured within said housing and arranged to output heat, visible light and infrared radiation responsive to current flow through said filament, said housing arranged to:
allow said infrared radiation output by said incandescent type bulb to irradiate the skin; andheat air within said formed air cavity responsive to the heat output by said incandescent type bulb, wherein the heated air within said formed air cavity forms a temperature gradient between said incandescent type bulb and the skin via said opening thereby heating the skin; anda control and driving circuitry in electrical communication with said incandescent type bulb and operative to output a train of pulses exhibiting an on time when current is driven through said filament and an off time when current is not driven through said filament, said off time greater than or equal to said on time, said off time of a duration such that said infra-red radiation irradiating the skin falls, during said off time, to no less than 25% of its maximum value, and wherein the visible light output of said incandescent type bulb falls to a near zero value during said off time.
