Definitions

  • Vertical illuminance determines preferred lighting level.
  • the invention relates to a method of enabling an artificial lighting system to automatically control a lighting level caused by daylight and by artificial lighting means.
  • the method comprises sensing a lighting level and enabling the system to adjust the artificial lighting means in dependence on the sensed lighting level.
  • Lighting can dramatically affect this circadian rhythm. The mood and behaviour of an individual thus turn out to show a dependence on environmental lighting. Lighting optimized with regard to a person's preferences is found to contribute in a positive way to his or her sense of well-being and, hence, to his or her performance or behaviour. See for more background information, for example, U.S. patent 5, 163,426.
  • the above serves to emphasize the importance of regulating the aggregate lighting level stemming from daylight and artificial lighting sources combined, and in particular the control of lighting systems in domestic environments, offices, plants, public buildings and places, hospitals, ocean liners, aircraft, etc.
  • working plane illuminance is considered the dominant parameter.
  • Typical known daylight dimming systems are designed to primarily keep a working plane illuminance, i.e. , the aggregate effect of daylight and artificial lighting typically on a horizontal plane, substantially constant.
  • the invention provides a method as specified in the preamble, characterized in that the artificial lighting means is adjusted substantially in dependence on the sensed lighting level associated with light incident on a substantially vertical plane.
  • the invention is based on the insight gained by experiments conducted to study user behaviour and response in window zone offices lit by a combination of daylight and artificial lighting.
  • the experiments have led to the conclusion that the experimental data do not agree with conventional lighting engineering practice and standards, and with daylighting theories and techniques. This is believed to be at least partly due to the fact that horizontal working plane illuminance is conventionally considered to be the dominant parameter in determining the required lighting levels.
  • artificial lighting standards were primarily developed excluding daylight contributions.
  • the experiments demonstrate that vertical plane illuminance or vertical plane luminance and spatial illuminance ratios or spatial luminance ratios that involve the vertical plane illuminance and luminance, respectively, determine the lighting levels preferred by the tests persons.
  • the sensing may comprise sensing an illuminance (incident light) or a luminance (scattered or reflected light) of the substantially vertical plane.
  • the artificial lighting means may be adjusted substantially in proportion to the sensed lighting level.
  • FIG. 1 schematically shows an office interior lit by daylight and artificial lighting.
  • Fig. 1 schematically pictures an office 100 with a desk 102, a chair 104, a window 106 provided with blinds 108, and lighting units 110, 112, 114 and 116.
  • Lighting units 1 10-116 and blinds 108 form parts of a system to control an aggregate lighting level caused by daylight entering through window 106 and the light from units 1 10- 1 16.
  • Blinds 108 typically reduce daylight levels in the room by 20 - 50% , but may still allow for a "view out”.
  • sensors 118 and 120 are arranged to sense the luminance or illuminance of relevant vertical planes, here the walls.
  • sensors 118 and 120 are located at eye-level, e.g. , with regard to a seated person so as to sense light representative of that perceived by the person.
  • Sensors 118 and 120 are coupled to a control system (not shown) that controls the lighting level contribution of units 1 10-1 16 in accordance with the person's individual preferences determined in advance.
  • the control system also controls daylight entrance.
  • daylight entrance is governed by controllable daylight entrance means such as blinds 108 or, alternatively, window panes whose transparency can be varied (not shown) to allow adjusting the entering daylight in accordance with the person's individual preferences.
  • a daylight sensor may be located inside the office and close to window 106, e.g. , integrated with the glass panel of the window.
  • sensors are provided to sense the horizontal luminance and/or illuminance e.g. , with respect to the top surface of desk 102. This enables the control system to control the spatial luminance or illuminance ratios, e.g., vertical versus horizontal contributions.
  • the control system preferably is to be customized or re-programmed so as to meet any individual's preferences.
  • the control system typically may include a rule-based controller such as a fuzzy controller to allow for a high degree of user-f ⁇ endhness regarding programming and to allow for a high degree of versatility.

Abstract

La présente invention concerne un système d'éclairage artificiel permettant de réguler automatiquement le niveau d'éclairage composite formé par la lumière naturelle et un moyen d'éclairage artificiel, en incidence sur un plan sensiblement horizontal, cette régulation ayant pour objet de créer un environnement d'éclairage ergonomiquement optimal. La détection du niveau d'éclairement permet au système de régler le dispositif d'éclairage artificiel sensiblement en fonction du niveau d'éclairement détecté associé à la lumière incidente sur un plan sensiblement vertical.
