Abstract
The invention relates to an infrared device comprising a resistive element suspended in a cavity formed in a main element, and capable of transmitting infrared radiation when it is fed with an electric current. In particular, the main element is at least partly covered on the outer surface thereof and/or the inner surface thereof with a reflective coating. The use of the reflective coating makes it possible to at least partly contain infrared radiation transmitted by the resistive element in the cavity.
Claims20
An infrared device for generating an infrared radiation, comprising:
- a main element comprising an external surface and an internal surface, the internal surface defining a cavity;
- at least one resistive element for emitting an infrared radiation when a current flows therethrough, said at least one resistive element being held in suspension, by at least two suspension arms, in the cavity, said suspension arms being arranged to make an electrical connection between the resistive element and two connection terminals disposed outside the cavity and said suspension arms being anchored to the main element,
- wherein at least one of the external surface and the internal surface are, at least partly, coated with a reflective coating, said reflective coating having a reflectivity coefficient of at least 90% in a range of infrared wavelengths likely to be emitted by the at least one resistive element, the reflective coating being also arranged such that the infrared radiation emitted by the resistive element and reflected by said coating is, at least partly, absorbed by the resistive element.
