In this case, only a single type of light ⁇ panel must be kept on site for maintenance purposes; a defective light source 52 or 66 can then be exchanged as a kind of unitary module.
  • at least one first lighting device here in the form of one of the two side lighting devices 44 or 46 or in the form of the ceiling lighting device 48, and a second lighting device, here in the form of the other side lighting device 46 or 44 or the ceiling lighting device 48, if this does not already define the first lighting device. Due to the low-glare lighting effect of the homogeneous luminous surfaces of the luminous panele 52, 66 is a high Ergonomics in the test chamber 18 ge ⁇ ensured because the workers working there tire less quickly than other light sources.

Abstract

L'invention concerne une installation de contrôle optique de zones superficielles (16) d'objets (12), en particulier de carrosseries peintes (14) de véhicules, laquelle installation comprend un dispositif de production de lumière de contrôle (28) au moyen duquel des objets (12) situés dans une zone de contrôle (18a) peuvent être exposés à une lumière de contrôle (30) et un modèle de contrôle (32) peut être créé sur la zone superficielle (16). Un système d'éclairage (42) comprend plusieurs unités d'éclairage (50, 64) pouvant émettre la lumière de contrôle (30). La couleur et/ou l'intensité de la lumière de contrôle (30) peuvent être réglées sélectivement au moyen des unités d'éclairage (50, 64).
