Abstract A plurality of fluorescent lamps (30, 30 and so on) are disposed so as to be unevenly distributed in the periphery of an upper space above and opposing a sample placing surface (21) in an environmental test room (11). The irradiance distribution of the light from the fluorescent lamps (30, 30 and so on) on the sample placing surface (21) is set to be within the range of ± 25% with respect to the irradiance at the center of the sample placing surface (21). L'invention concerne une pluralité de lampes fluorescentes (30, 30 etc.) qui sont disposées de façon à être distribuées de façon non régulière dans la périphérie d'un espace supérieur au-dessus et opposé à une surface de placement d'échantillons (21) dans une pièce de test environnemental (11). La distribution de rayonnement de la lumière provenant des lampes fluorescentes (30, 30 etc.) sur la surface de placement (21) est fixée pour être dans la plage de ± 25 % par rapport au rayonnement au centre de la surface de placement d'échantillon (21).
