Zusammenfassung:	An infrared radiation deflector (100) for an elongate infrared lamp (110), the radiation deflector (100) comprising opposing first and second elongate side walls (130_1, 130_2); at least one end support (170) connecting the ends of the side walls (130_1, 130_2); an upper opening (140) and a lower opening (150) arranged to pass lamp radiation to an exterior of the radiation deflector (100); and a mounting point (172) provided at the/each end support (170) for mounting the infrared lamp (110) and defining between them a lamp axis location (114); wherein the first and second elongate side walls (130_1, 130_2) comprise a first elongate mirror (130_1) and a second elongate mirror (130_2) extending parallel to the lamp axis location (114) and along at least a lower internal portion of the respective first and second side walls (130_1, 130_2); wherein the lamp axis location (114) extends along and between the first mirror (130_1) and the second mirror (130_2), the first and second mirror (130_1, 130_2) each having a concave surface with respect to the lamp axis location (114); and wherein the first mirror (130_1) is an upward deflecting mirror and further arranged to be concave with respect to the upper opening (140) for redirecting at least a portion of direct lamp radiation through the upper opening (140). Déflecteur de rayonnement infrarouge (100) pour lampe infrarouge allongée (110), le déflecteur de rayonnement (100) comprenant des première et seconde parois latérales (130_1, 130_2) allongées opposées; au moins un support d'extrémité (170) reliant les extrémités des parois latérales (130_1, 130_2); une ouverture supérieure (140) et une ouverture inférieure (150) conçues pour laisser passer un rayonnement de lampe (100) vers l'extérieur du déflecteur de rayonnement; et un point de montage (172) prévu au niveau du/de chaque support d'extrémité (170) pour monter la lampe infrarouge (100), et définissant entre eux un emplacement (114) d'axe de lampe; les première et seconde parois latérales (130_1, 130_2) allongées comprenant un premier miroir allongé (130_1) et un second miroir allongé (130_2) s'étendant parallèlement à l'emplacement (114) d'axe de lampe et le long d'au moins une partie interne inférieure des première et seconde parois latérales (130_1, 130_2) respectives; l'emplacement (114) d'axe de lampe s'étendant le long des premier et second miroirs (130_1, 130_2) et entre ces derniers, les premier et second miroirs (130_1, 130_2) possédant chacun une sur
