Definitions

  • the present invention relates to a control device functioning as part of a lighting system, which is capable of working the lighting system regarding its operational, control, and programming functions, either automatically on the basis of measuring the level of lighting or by means of Control commands issued by a system operator.
  • control systems which include one or more centralized control devices or controllers for lighting, and these, on the other hand, control the operation of dimmers or controllable electronic ballasts attached thereto.
  • the dimmers are arranged in separate clusters or channels, wherein the dimmers of each channel perform the same control function, for example by adjusting to each desirable level of lighting.
  • the centralized controllers have also been provided with operating devices or actuators, whereby the system can be subjected to human commands. These may include switching the lights on or off, bringing the lighting continuously in a desired direction, or switching onto a desired, pre- programmed level of lighting.
  • actuators may comprise for example sets of push-buttons or rotary potentiometers installed in a space to be illuminated. Some of the actuators can be used for feeding desired function parameters (e.g. information about illuminance) into the system.
  • desired function parameters e.g. information about illuminance
  • One control system operating this way has been described in the Applicant's patent FI 74828, wherein a common analogic control bus can be fitted with a plurality of control potentiometers for a so-called multipoint control.
  • the Applicant's Patent FI 94204 discloses a control device for lighting, which is intended for performing lighting control on the basis of the illuminance of an ambient space
  • a control unit can be included in each individual lighting fixture in the system for providing, for example, a variable, daylight-compliant lighting in spaces where the reduction of energy consumption by lighting is desirable
  • the exploitation of natural light coming in through windows has proved to be quite a demanding task in terms of preferably maintaining a sufficiently constant illuminance on various surfaces of a space to be illuminated. This is due to the fact that changes occurring in natural light may be major phenomena simultaneously both in terms of the dynamics and speed thereof, such as the sun being blocked by a cloud.
  • this type of systems include a plurality of sensors intended for the measurement of lighting, some measuring e.g. natural light and some the aggregate light consisting of natural light and artificial light.
  • the sensors have traditionally been mounted on wall surfaces in rooms.
  • the system control unit houses a logic circuit for determining the necessary control measures proportional to the relationship of artificial light and natural light.
  • the control unit delivers control commands for dimmers and electronic ballasts or strives to limit the share of natural light, e.g. by controlling shutters. Said control measures are based on quite a complicated control algorithm.
  • Such transmitters are useful, particularly when the system operator is physically moving in a space to be illuminated and has no desire to be compelled to use actuators permanently cabled to the system. It is highly typical for small infrared transmitters and similar units in office use that, when set e.g. on top of office desks, such units are often covered by other articles (e.g. papers). Consequently, the system operator is usually forced to manually pick up said actuator and to point it toward the system receiver for giving desired control and encoding commands to the system.
  • This invention introduces a simple control device for a lighting system for the transmission of control or encoding measures, as well as illuminance data.
  • the invention enables also a sensor intended for the measurement of lighting intensity to be positioned as optimally as possible in terms of the system operation.
  • this eliminates the above-described problem about usually needing a plurality of said control devices and about impeding the operation of a control device by other articles on top of the device, for example by sheets of paper common in an office environment.
  • Another problem that is resolved is the fact that the feed of operating voltage to a portable or movable control device merely by means of batteries or rechargeable accumulators is quite unreliable and often quite expensive with regard to its operating costs.
  • the invention is characterized by what is set forth in the annexed claim 1.
  • control devices unavoidable in a compliant lighting system and a light sensor for a single unit, the connection of which to a lighting control system is effected by means of an infrared or radio link.
  • the optimal location or site for the lighting-compliant light sensor of the system is on a surface whose level of lighting is to be maintained constant, i.e. generally e.g. on top of an office desk.
  • the unit is constructed in such a way that it houses the above-mentioned service elements and is intended for use particularly on a desk, which makes it easy for the operator to perform desired control measures and, on the other hand, the light sensor is conveniently in the vicinity of the desk top and is thereby capable of measuring as optimally as possible the lighting intensity of a target to be illuminated.
  • the unit has its power supply arranged by means of batteries, rechargeable accumulators or a photocell-based power source or a combination thereof. Of course, it is also possible to plug the unit to the power supply mains.
  • the service unit can be designed conveniently in such a way that it cannot be normally covered by foreign objects, whereby the light measuring function or communication with the rest of the system over the infrared link is not jeopardized.
  • the use of an infrared or radio link is preferred, as this makes it simple to provide a desired directional effect for the radio signal.
  • Fig. 1 shows a fundamental design for a lighting control system, comprising a variety of intelligent control devices, actuators therefor, light sources, and electronic ballasts therefor
  • Fig. 2 shows logical nodal points for a lighting control system, and a basic design for a transmitter used for the control or encoding thereof
  • Fig. 3 shows one configuration for a service unit provided with a control transmitter
  • Fig. 4 shows another preferred mechanical design for a service unit provided with a control transmitter
  • the control system shown in fig. 1 is provided with an infrared receiver 1 for receiving control commands from a control transmitter 25, included in a portable service unit 2 and fitted with a constant light sensor 23 which supplies the system with a status signal proportional to the illuminance of a space to be illuminated.

  • a switch 5 can be used for controlling the lighting in an on/off mode, and a unit 6 can be provided with a so-called presence sensor for detecting the presence of a person in a space to be illuminated.

  • the system may also include electronic dimmers or electronic transformers 10 for halogen lamps, along with lamps 11.
  • the duty of a smart control unit 7 is to control or govern the ballasts and dimmers 8, 10 in compliance with information received from the actuators 1...6 and preprogramming of the unit.
  • Fig. 2 takes a closer look at a transmitter 12, the control element of which is a unit 13.
  • a modulator 14 uses a unit 15 for providing the transmission signal with encoding or control information set by a unit 16.

  • the service unit shown in fig. 3 comprises a pyramidal housing element 3, the bottom portion of which constitutes a solid footing 21 which maintains the service unit and its integral control transmitter 25 in a proper operating position, e.g. on a desktop, and which, by virtue of its design, precludes any blanketing effect by other articles.
