Definitions

  • Sensors play a key role in modern lighting control systems and assist in providing maximum energy efficiency, safety and comfort for the end users.
  • These sensors are most often installed in the ceilings of rooms or corridors.
  • these electronic sensors are self contained within a housing the front side of which has different sensing elements incorporated for the detection of movement in a room or corridor, a light sensor for measuring the amount if light, a visual indicator for user feedback and a receiver for use with a separate wireless remote control.
  • Electronics associated with these sensors provides control over the local lighting on the basis of the detected movements and the measured amount of light.
  • the control algorithms employed and their parameters change substantially based on the application and user's environment. In the state of the art this is typically done by using a switch on the back side of the electronic sensor housing that has been installed in the ceiling. The switch is located on the back side for example because of the need to keep the size of the electronic sensor housing as small as possible.
  • a change in operation demands access to the ceiling, removal of the electronic sensor housing from it's mounting and then adjustment of a switch setting on the back side of the electronic sensor housing to change the operation mode and reinstallation of the electronic sensor housing into the ceiling.
  • a drawback in the state of the art has been that not enough attention has been made to make the electronic sensor housing take ground into lighting environment, but the housing has been well visible in the ceiling, for example thus arising irrelevant unconsciousness and questions of its use purpose in the ceiling.
  • the object of the invention is to accomplish an electronic sensor housing for making the switching of lighting modes easy. This is important as it allows the initial mode of operation to be set without disturbing the installation and changes to be made throughout the installation's lifetime without a need to employ skilled personnel e.g. electrician.
  • the object of the invention is also to make the electronic sensor housing as invisible as possible in lighting environment, where the housing is in use. This is achieved by an electronic sensor housing comprising on the front side of the housing a movement detector for detecting movements in a detection space and a light sensor for measuring the amount of light and inside of the housing a control unit for controlling lighting on the basis of the detected movements and the measured amount of light.
  • the electronic sensor housing comprises on the front side of the housing a switch ring at least partly surrounding the movement detector for switching a convenient operation mode for lighting, the electronic sensor housing comprises different contact areas for different operation modes for lighting, the switch ring comprises a contact part for contacting from one contact area to another during the switching of the convenient operation mode for lighting by using the switch ring on the front side of the electronic sensor housing, and the electronic sensor housing comprises a changeable fascia, which is attachable onto the front side of the electronic sensor housing and detachable from the front side of the electronic sensor housing.
  • the invention is based on that the electronic sensor housing comprises on the front side of the housing a switch ring at least partly surrounding the movement detector for switching a convenient operation mode for lighting.
  • the different contact areas in the electronics sensor housing arranged for different operation modes for lighting and a contact part for creating a connection between said contact part and a selected contact area make possible the switching of the convenient operation mode for lighting by using the switch ring on the front side of the electronic sensor housing.
  • the invention is further based on utilization of a changeable fascia, which makes the electronic sensor housing to take ground into a luminaire.
  • the fascia is attachable onto the front side of the electronic sensor housing and detachable from the front side of the electronic sensor housing.
  • the benefit of the invention is that switching between lighting modes of operation has been made safe, and easy to use, by providing access from front of unit, without a need to remove the electronic sensor housing from the installation and also without a need to increase the physical size of the electronic sensor housing.
  • the benefit of the invention is also that the electronic sensor housing has taken well ground into lighting environment.
  • Figure 1 presents a front side of the electronic sensor housing according to the preferred embodiment of the present invention.
  • This electronic sensor housing comprises on the front side of the housing a movement detector 100 for detecting movements in a detection space and a light sensor 102 for measuring the amount of light.
  • the electronic sensor housing comprises on the front side of the housing a switch ring 104 surrounding the movement detector 100.
  • Both the movement detector 100 and the light sensor 102 can be shielded to reduce their field of view. For example for the movement detector this shielding function is performed by a shield 101.
  • FIG 2A is presented a perspective view of electronic sensor housing parts according to a preferred embodiment of the present invention.
  • a control unit 103 for controlling the lighting on the basis of the detected movements and measured light intensity. Movement in the detection space is sensed by the combination of the movement detector and the control unit, which process raw signal data from the movement detector.
  • Electronic sensor housing elements 105 are used in the construction of the electronic sensor housing.
  • Figure 2B presents a side view of electronic sensor housing parts according to the preferred embodiment of the present invention.
  • the function of the switch ring is the switching of a convenient operation mode for lighting.
  • the switch ring 104 combines a hand actuated multi-position switch, operated from the front of the housing, with an incorporated light pipe to provide visual feedback.
  • the switch ring 104 is essentially protruding from the electronic sensor housing to make the hand actuation easy.
  • the electronic sensor housing comprises of sets of contacts 108 ( Fig. 2A ) each associated with a lighting mode, a wiper contact part 110 ( Fig. 3 ) to make connection between the contact part 110 and the contact sets 108 as the ring is rotated, a visual marker to show the switch ring orientation and positive tactile feedback at each switch position.
  • the wiper contact part 110 ( Fig. 3 ) slides from one contact area 108 ( Fig 2A ) to make a contact to another contact area 108 during the switching of the convenient operation mode for lighting by turning the switch ring 104 on the front side of the electronic sensor housing ( Fig. 1 ).
  • the first preferable operation mode can be switched on already before the electronic sensor housing leaves the factory. Then the electronic sensor housing is installed for example on the ceiling of a room or corridor for controlling the lighting.
  • the electronic sensor housing can also be installed inside the light source. When for example use of a room changes from class room to negotiation room, a need arises to change the operation mode. Then without removing the electronic sensor housing from the installation, the switch ring 104 is turned and a connection to a new operation mode is made.
  • the electronic sensor housing can comprise for example a simple selection of 6 pre-set operation modes, e.g. office, class room, corridor, etc. For example, delays and sensitivities of lighting are programmed individually for different operation modes.
  • FIG. 3 presents the switch ring according to the preferred embodiment of the invention.
  • the wiper contact part 110 is constructed for example by utilizing a wiper contact made by chemical etching process. In this construction a plastic part 112 retains wiper and provides spring tension. Also, a tactile feedback can be utilized.
  • the control unit 103 is preferably a processor unit. It can comprise a set up memory for different modes of lighting and/or a programmable processor unit for programming mode settings during the use of the electronic sensor housing.
  • the control unit can also provide feedback to the user according to the present invention by means of an integrated light pipe in the switch ring plastic part 112. Also in an embodiment according to the invention the control unit 103, or part of it, can locate also in another location than in the electronic sensor housing.
  • FIG 4 is presented a perspective view of a changeable fascia 115 according to the second preferred embodiment of the present invention, which is attachable to and detachable from the front side of the electronic sensor housing.
  • Figure 5 presents a perspective view showing an example of a fascia 115, which has taken ground into the luminaire 117 according to the second preferred embodiment of the present invention.
  • the changeable fascia 115 can be supplied to match as closely as possible the colour of the luminaire 117 to which it is fitted.
  • the product is designed for example to snap fit into a rectangular aperture in the luminaire. From the outside only the fascia and sensors 102, 106 are visible. By changing the colour of the fascia 115 we can ensure the electronic sensor housing remains as unobtrusive as possible.
  • FIG 5 is illustrated that by changing the grey coloured fascia 115 to pure white fascia, it is possible to make the fascia 115 more unobtrusive.
