Definitions

  • This invention relates to a light fitting, and in particular to a recessed light fitting.
  • the dimensions of the light fitting to be recessed are to be suitable for the installation place in question.
  • a drawback with the above solution is that a plurality of variations need to be manufactured of the same light fitting.
  • the object of the present invention is to solve the above-described problem and to provide a light fitting which may be installed in a simple and flexible manner in places whose measurements differ from one another. This is achieved with a light fitting in accordance with the attached independent claim 1.
  • connection device box When a connection device box is arranged in connection with the frame of the light fitting, some of the parts belonging to the light fitting may be arranged apart from the actual light fitting frame, whereby the shaping of the light fitting frame becomes more flexible such that it will be utilizable in a variety of installations. Moreover, when the light fitting frame and the connection device box are manufactured such that in connection with installation they may be arranged in alternative positions in relation to one another, it is possible to provide a light fitting that is adaptable to use more flexibly than before. Thus, depending on the installation place, the mutual position of the connection device box and the frame may be arranged such that the light fitting is suitable for installation in that particular installation place.
  • Figures 1 and 2 show a first embodiment of a light fitting 1 seen obliquely from above and obliquely from below.
  • the light fitting 1 comprises a frame 2, which may be made of a suitable plastic or metal material and which is embedded at least partly in a surrounding structure in connection with installation.
  • the frame 2 of the light fitting 1 may accommodate one or more light sources 10.
  • the question may be of high-power light emitting diodes, i.e. so-called high-power leds, whose power may be 1 to 3 W/piece, for instance.
  • the light sources 10 are arranged in the light fitting frame 2 such that the light produced thereby is able to propagate to the space under the light fitting through an open lower part of the frame 2.
  • the example of Figures 1 and 2 employs fasteners 4 arranged on the outer surface of the frame 1.
  • the distance which these fasteners 4 project from the frame 2 is adjustable, so that the light fitting 1 can be secured into place in the surrounding structure by means of the fasteners which are pressed against the surrounding structure.
  • the fasteners may be, for instance, metal wire loops or plastic pins, which press outwardly from the frame due to an intermediary piece 5, which intermediary piece 5 moves along a screw 6, when the screw head is turned from inside the light fitting frame 2 with a screw driver, for instance.
  • a connection device box 7 is secured to the frame 2 through a securing member 8.
  • the securing member 8 may be, for instance, a screw or a rivet, through which the connection device box 7 is pivoted to the frame 2 such that their mutual positions may be changed by pivoting the connection device box about the securing member 8.
  • a plurality of securing members 8 may be employed, for instance, a plurality of screws and holes provided for them, whereby the connection device box 7 is securable to the frame 2 by means of these securing members in any one of the plurality of alternative positions in relation to the frame.
  • the frame 2 and the connection device box 7 are provided with bulges and recesses which enable the securing of the connection device box 7 to the frame 2 by using so-called click-into-place connection, in which the reliefs are pressed in the recesses.
  • the connection device box may be secured in a desired position in relation to the frame.
  • FIGs 3 to 5 illustrate the installation of the light fitting 1 of Figures 1 and 2 in various locations.
  • the light fitting 1 is shown embedded in a ceiling 15.
  • the light fitting frame 2 penetrates partly inside the structure of the ceiling 15 until a collar in its lower part will be against the lower surface of the ceiling 15.
  • connection device box 7 is arranged in such a position in relation to the frame 2 that it projects to the left from the frame 2, in parallel with the ceiling 15. In that case the recess installation depth D1 of the light fitting 1 is at its smallest. In this position the light fitting 1 is utilizable, for instance, for a ceiling structure, where the thickness D2 of the ceiling is relatively small. Thanks to the location of the connection device box 7 a conductor connected to the power supply network may be readily coupled in a space above the ceiling 15 to a connector 9 locating in the connection device box. Thus, it is possible to arrange power supply through the connection device box to the light source 10 or light sources, which are also coupled to the connector 9. In practice, the connector 9 may be designed to receive individual electric conductors. Alternatively, it may be a connector that receives a plug.
  • connection device box 7 between the connector 9 and the light source, when necessary.
  • connection device box 7 is pivoted about the pivot point provided by the securing member 8 to the right in relation to the frame 2.
  • the securing member 8 constituting the pivot point is arranged eccentrically to the connection device box 7, i.e. offset from the centre line 12 of its side part. Consequently, the recess installation depth D1 of the light fitting 1 is larger in the case of Figure 4 in comparison to Figure 3 .
  • the thickness D2 of the ceiling may also be larger in the case of Figure 4 in comparison to Figure 3 . Consequently, thanks to the eccentricity, it is possible to provide three different depths for recess installation, depending on the position ( Figure 3, Figure 4 or Figure 5 ) to which the connection device box is pivoted.
  • connection device box 7 is pivoted about the pivot point provided by the securing element 8 almost to an upright position in relation to the frame 2, to be above said frame.
  • the recess installation depth D1 of the light fitting 1 is at its largest.
  • the thickness D2 of the ceiling may be considerably larger than in the cases of Figures 3 and 4 .
  • Figures 6 to 7 illustrate the installation of the light fitting 1 of Figures 1 and 2 in a fixture housing 14.
  • the fixture housing 14 consists of a hollow, cylindrical part inside which the light fitting is recessed.
  • the connection device box 7 may be arranged in the upright position, as shown in Figures 6 and 7 , or alternatively, it may be turned to a horizontal position, as shown in Figures 3 and 4 .
  • FIG 6 where the light fitting 1 is shown partly cut open, shows in addition to the light sources 10 a movement sensor 13, which is not necessary in all implementations.
  • the movement sensor 13 may control supply of electricity to the light sources 10 such that they are only supplied when the movement sensor 13 has detected a person moving in a dark space beneath the light fitting, for instance.
  • the movement sensor 13 may be a PIR (Passive Infrared) movement sensor, for instance, which allows detection of a person in the space on the basis of thermal radiation, a movement sensor based on radar technology, which includes a microwave transmitter and a microwave receiver, or an ultrasound receiver, which allows detection of motion in a space.
