Description

Method and system of remote lighting control
The present invention relates to a method and system of remote lighting control, especially of lighting commercial and conference facilities and objects of historical value.
It is known from the Japanese patent description, JP7312296, the system for remote lighting control. The objective of this solution is to facilitate spot light control. This system comprises a device for altering direction of light and a control device. In order to change direction of light, the control device transmits signal of changing direction wireless to the device for altering direction of light. The device used for altering direction of light includes an element receiving the wireless-sent signal for altering direction and an element assessing direction from which this signal comes. At the time of sending the signal by the control device from the place where light should be directed, the receiving element receives this signal and the assessing element assesses the direction from which the signal comes, and then the device for changing direction of light changes direction of light to where the received signal comes from. Thus, a wireless control device is sufficient to change direction of light. The disadvantage of the described solution is mostly the fact that light may be directed only to the site of the control device, thus this device must be each time located in the place to be lit.
From the international publication No. WO02/16824, it is known the method and system of controlling direction, preferably also intensity of lighting. This system comprises the indicating device, which assigns the place and direction of changes in the location of light, the receiving device which receives the signal transmitted by the indicating device and the control device which directs the source of light to the place indicated by the control device. This solution requires preparing the appropriate room provided with a properly located, fixed permanently, cameras or other detectors tracking the indicating device. The solution requires exact adjustment of the method of controlling sources of light to specific rooms, as it comprises separate units detecting the indicating device, the sources of light and the main control unit, and light is directed directly to the indicator, and not to the place indicated by it.
There are known lighting fittings of an ability to move, such as systems of disco or stage lighting wherein the movement is controlled by the operator or with a pre- programmed computer, or their movement is dependent on sound intensity or volume. These solutions allow only simple movement of the fittings.
The disadvantage of the known solutions is lack of the possibility of remote determination of a site where light is to be directed. The solution according to the invention allows remote direction of light to a site remote from the indicator operator, which allows making easy and fast changes in lighting. The known solutions cannot acquire visual information from cameras integrated with the lighting fitting with simultaneous direction of light to the sites indicated remotely.
The technical issue which needs solution is development of a new method of remote lighting control, which would allow remote directing of light from a moving lighting fitting to a facility selected with a laser indicator.
The technical issue which needs solution is development of a new system of remote lighting control, which would allow remote directing of light from a moving lighting fitting to a facility selected with a laser indicator.
The solution embodied in the method of remote lighting control, according to the invention, consists in the fact that first, after connecting the power supply to the lighting fitting, the camera and step motor controllers configuration stage starts. Then, the remote lighting control system enters the state of waiting for activation, which occurs by lighting the sensor activating the fitting with a laser indicator. When the laser spot is within the camera's field of vision, the lighting fitting changes its position so that the laser spot emitted by the laser indicator is in the centre of the area lit by the lighting fitting. By the meaning of 'laser spot' it should understood any light mark on the objects, emitted by a laser indicator. Movement of the laser spot causes movement of the light beam emitted by the lighting fitting so that the laser spot is always in the centre of the area lit by the lighting fitting. When the laser spot fades or when the laser spot is not in field of vision of the camera, the lighting fitting, after a defined time, moves into the condition of waiting for activation. Additionally, after the lighting fitting is activated, it can move for a defined time within the range of movement defined by the α and β angles in order to find the laser spot and then be positioned so that the found laser spot emitted by the laser indicator is in the centre of the area lit by the lighting fitting. Movement of the laser spot causes movement of the light beam emitted by the lighting fitting so that the laser spot is always in the centre of the area lit by the lighting fitting. When the laser spot fades or when it is not in field of vision of the camera, the lighting fitting, after a defined time, enters the state of waiting for another activation. When the laser spot is not detected on searching, the lighting fitting automatically returns to the position preceding the activation and enters the state of waiting for another activation.
The remote lighting control system according to the invention features is characterized in that the system is equipped with known remote laser indicator of any wavelength of the emitted light in the visual range, and the lighting fitting is fitted with a source of light connected with a light source power supply and an electronic control system connected with a camera, a sensor activating the fitting and a drive assembly. The electronic control system is additionally connected with a sound signalling device, preferably a piezoelectric speaker, as well as with any known communication module. The lighting fitting has a fixing element installed on a rotating output shaft from the gear, preferably worm and cone gear, allowing to reach rotation of the fitting with the rotation range β = 360 degrees, and is provided with a source of light and a camera, which are set on a common output shaft from the gear, preferably worm gear, allowing to reach movement of a deflecting source of light with the range of α = 90 degrees, while the theoretical optical axis of the light source is parallel to the theoretical optical axis of the camera. The sensor activating the fitting is made of a photo-resistor covered with an optical filter. The electronic control system comprises input buffers to which the camera is connected, connected with the main microcontroller, which is additionally connected with the camera through the microcontroller controlling the camera. The main microcontroller is connected with the sensor activating the fitting and two independent step motor controllers, and each of the listed elements of the system is powered from a power supply unit (not shown) for the control system and step motors. The lens of the camera on the external side is provided with a selective filter used for observation of the laser spot, adjusted to the wavelength of the light emitted by the laser indicator. The drive assembly has two step motors connected through the gear with output shafts, perpendicular to each other, which in turn are connected with the electronic control system. The step motor controllers support the motors in steps, preferably in the micro-step procedure. One of the step motors is connected by means of the worm gear and the cone gear with the output shaft with the β = 360 degrees range of movement, and the other step motor is connected by means of the worm gear with the output shaft with the α = 90 degrees range of movement, in which the source of light and the camera are set. The stages of accelerating and braking the step motors run smooth in accordance with the trapezoid curve. The communication module allows connection of an electronic control system to a external control unit (not shown), preferably to a computer, which allows making changes of parameters of the main microcontroller, the camera and the controllers of step motors, and for connection of the lighting fitting with other lighting fittings and execution of movement programs of an individual lighting fitting or of sets of fittings connected with each other.
The advantage of the method and system according to the invention is the possibility of touchless changing of position of the lighting fitting, which is especially important due to the possibility of occurrence of high temperature of the light source and lack of the possibility of frequent switching the light source off to cool it down. The solution according to the invention allows the remote control of the lighting fitting without necessity of adjustment of the room in which it is located, and without the necessity of prior determination of fitting position in the space in reference to the camera. The lighting fitting according to the invention is a fully autonomous unit, which, after hanging up at any location in the room, is ready for independent functioning.

Activation of the lighting fitting 1 is done by lighting the sensor activating the fitting 6 with the laser indicator. When the laser spot is within the camera's 5 field of vision, the lighting fitting 1 changes its position so that the laser spot emitted by the laser indicator is in the centre of the area lit by the lighting fitting 1.
