Abstract: Infrared filler of a light source for healing an object The invention relates to an optical interface for transmitting at least some infrared rays emitted from at least one light source so as to heat an object above a threshold temperature, wherein the object stops to transmit and absorbs from an infrared wavelength threshold, the optical interface comprising: a substrate; an interference filter on the substrate having an infrared spectral transmission T exhibiting: a first portion in the near infrared with high T, a second portion in the far infrared with low T, and an intermediary portion between first and second portions, comprising a spectral transition between high T and low T, having T=50% at a wavelength ?0 lower than the wavelength threshold; wherein, in a range of wavelengths, the mean value of low T is adjusted so that the light source can provide in this range a complementary heating energy necessary for the total healing temperature of the object exceeds the threshold temperature.

Abstract: A lamp includes a lamp vessel, an incandescent body arranged in the lamp vessel, and current supply conductors connected to the incandescent body. The incandescent body is configured to emit a radiation spectrum including a visible portion and an infrared portion. An outer envelope around the lamp vessel has a reflective film adapted to transmit a first part of the visible portion and a second part of the infrared portion, the second part being greater than the first part.

Abstract: A heating system includes a reflector having a concave section symmetrical with respect to an axis of symmetry. In addition, a first radiation system having at least a first radiation member is capable of emitting a first type of radiation and a second radiation system having at least a second radiation member is capable of emitting a second type of radiation. The second radiation system is positioned in a direction parallel to the axis of symmetry with respect to the first radiation system.

Abstract: The invention relates to a lamp comprising a lamp vessel (101), an incandescent body (102) arranged in the lamp vessel and current supply conductors (103) connected to the incandescent body. The incandescent body is intended to emit a radiation spectrum comprising a visible portion and an infrared portion. The lamp further comprises an outer envelope (104) around the lamp vessel. The outer envelope comprises a reflective film (111) adapted to transmit a first part of the visible portion and a second part of the infrared portion, the second part being greater than the first part.

Abstract: The invention relates to a heating system used, for example, in applications such as the drying of paint. This heating system comprises a reflector (201, 505) having a concave section symmetrical with respect to an axis of symmetry (208, 508). It comprises in addition a first radiation system having at least a first radiation member (202, 501) capable of emitting a first type of radiation and a second radiation system having at least a second radiation member (203, 502) capable of emitting a second type of radiation. The second radiation system is positioned in a direction parallel to said axis of symmetry with respect to the first radiation system.
