  • Lamp for heating having a reflective film for transmitting different radiation portions
    Patent number: 7456556
    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.

  • Heating system comprising at least two different radiations
    Patent number: 7254319
    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.

  • Heating system comprising at least two different radiations
    Publication number: 20060051078
    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.
