Installation for controlling the lighting level of premises
First Claim
1. An installation for controlling the lighting level of premises provided with at least one opening permitting entry of natural light and fitted with means of masking the said opening and with means of artificial lighting (M(1) to M(N)), means associated with control operators (IP(1) to IP(N)), this installation comprising photosensitive means (CL) for measuring the lighting level, means (P1, P2;
- P) of automatic control of the operators monitored by photosensitive means as a function of a lighting set point, means of adjusting the set point consisting of manually actuatable contacts (PA, PB, PC) and means (PI, P2;
P) of storing this set point, and in which the means of automatic control comprise a logic processing unit (P, CAN, H;
P1, CAN1, H1, P2, H2) electrically connected, by galvanic link or otherwise, to the photosensitive means (CL), to the manually actuatable contacts and to the operators, the logic processing unit being programmed to read the state of the contacts and the values measured by the photosensitive means and to emit signals for more or less lighting directed towards the operators, on the one hand as a function of the state of the said contacts (PA, PB) and on the other hand as a function of the deviation between the set point value and the value measured by the photosensitive means, and to record, at an instant determined by the user, a lighting value measured by the photosensitive means, wherein it comprises means (P1, P2;
P) of effecting successive control, in a predefined order, of the masking means and of the lighting means, these control means being arranged in such a way that they pass from one means (M(K)) to the next means (M(K±
1)) after a specified duration.

Abstract
Device for automatically controlling the lighting level of premises (A) having available one or more openings (B) to the outside. This device acts on means (V, S, E) of masking the openings and on means of artificial lighting with dimmer (L) as a function of a set point value corresponding to a lighting level established by the user and recorded instantaneously. The masking and lighting means are furthermore controlled in a specified order so as to limit the consumption of energy. In certain implementations, this order is determined as a function of the deviation between a measured temperature and a threshold temperature.
