Abstract

Device comprising a light bulb positioned inside a reflector made of a transparent material with a selectively reflective surface (4) capable of reflecting the visible radiation generated by the bulb (2) whilst at the same time allowing heat radiation to pass through it, whereas on the outer side of this reflector there is a reflective surface (6, 8) for the heat radiation passing through the reflector (1), the device being characterised in that the reflective surface (8) for the heat radiation is formed on a backing piece positioned on the outside of the reflector. <IMAGE>
