DETAILED DESCRIPTION OF THE INVENTION

[0046] The present invention will now be described hereinafter with reference to the accompanying drawings, in which exemplifying embodiments of the present invention are shown. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments of the present invention set forth herein; rather, these embodiments of the present invention are provided by way of example so that this disclosure will convey the scope of the invention to those skilled in the art. In the drawings, identical or similar reference numerals denote the same or similar components having a same or similar function, unless specifically stated otherwise.

[0047] FIG. 1 shows a device system 1 comprising a suspensible device 2. The suspensible device 2 comprises a housing 3 comprising an active surface 5 and an attachment element 14 provided on an attachment surface 4. The attachment surface 4 is arranged opposite to the active surface 5. The suspensible device 2 depicted in FIG. 1 is a light-emitting device comprising at least one light source 6, as may be seen in FIGS. 4a and 4b. Further, the active surface 5 of the suspensible device 2 is a light-exit window.

[0048] The housing 3 depicted in FIG. 1 is substantially cylindric and comprise a lateral surface 3, a first base surface and a second base surface, and wherein the first base surface constitutes the active surface 5, and the second base surface constitutes the attachment surface 4. As mentioned above, the housing is preferably light-weight.

[0049] The suspensible device 2 further comprises a balancing element 7 arranged adjacent to the inner portion 4 of the attachment surface 4, such that the balancing element 7 is not visible, as may be seen in FIG. 3. As shown, the balancing element 7 is movable between a first position shown in FIG. 1, and a second position shown in FIG. 2 with respect to the suspension element 11 and the rest of the suspended device 2. Yet, the first end portion 9 of the suspension element 11 stays attached to the attachment element 14 (also mentioned cable support point 14) on the attachment surface 4 in a fixed position at/in/on the housing 3 both on the attachment surface 4 and with respect to the rest of the suspensible device 2 (except for the balancing element 7).

[0050] The balancing element 7 according to the present invention further comprises an actuating element 8 arranged for moving the balancing element 7 between the first position and the second position. The actuating element 8 depicted in FIGS. 1 and 2 is in the form of a lever arranged to be manually maneuvered by the user.

[0051] The balancing element 7 is an annular element having an aperture arranged in a peripheral portion of the balancing element 7.

[0052] The suspensible device 2 further comprise a flat optical element 5 arranged adjacent to the light exit window 5, as may be seen in FIGS. 4a and 4b.

[0053] The device system 1 further comprises a suspension element 11 comprising a first end portion 9 being attached to the attachment surface 5 of the housing 3, and a second end portion 10 being attachable to a fastening surface (not shown). When the suspensible device 2 is attached to the suspension element 11, a suspension angle is defined between the attachment surface 4 of the suspensible device 2 and the suspension element 11. The suspension angle has a first value when the balancing element 7 is in the first position, as shown in FIG. 1, and a second value when the balancing element 7 is in the second position depicted in FIG. 2. In other words, the value of the suspension angle changes when the balancing element 7 is moved from a first position to a second position. The device system 1 of the present invention thus offers the advantage of providing a suspended device 2 that may be directed in different directions by moving the balancing element 7 between the first position and at least one second position. The suspended device 2 may be directed in different directions by tilting and/or rotating the suspended device 2.

[0054] The suspended device 2 is mechanically connected to the first end portion 9 of the suspension element 11. Mechanical connection implies a direct contact between the suspended device 2 and the suspension element 11. Further, the suspended device 2 is electrically connected to the suspension element 11.

[0055] As depicted in FIG. 1, the first value of the suspension angle is approximately 30, i.e. the suspended device 2 is arranged such that the suspended device 2 is tilted from the position where the attachment surface 4 is pointing upwards to the position where the attachment surface 4 is pointing in a direction inclined in relation to the upward direction. In other words, the suspended device 2 shown in FIG. 1 functions as a spotlight.

[0056] As shown in FIG. 2, the second value of the suspension angle is 90. In other words, when the balancing element 7 has been moved from the first to the second position, the suspensible device 2 is moved to a position wherein the attachment surface 4 is pointing upwards, i.e. wherein the light emitted by the light source 6 is directed downwards.

[0057] FIG. 3 provides a detailed view of the actuating element 8, which is activated by the user when it is desired to tilt the suspended device 2.

[0058] FIGS. 5a and 5b show a device system 101 comprising a suspensible device 102. The suspensible device 102 comprises a housing 103 comprising an attachment surface 104 and an active surface 105.

[0059] The suspensible device 102 further comprises two balancing element 107, 107 arranged adjacent to the inner portion 104 of the attachment surface 104. The balancing elements 107, 107 are movable between a first position and a plurality of second positions.

[0060] Each of the balancing elements 107, 107 comprises an aperture 112, 112, a solid portion 113, 113, and an actuating element 108, 108 arranged for moving the balancing element 107, 107 between the first position and the second position. The actuating element 108, 108 depicted in FIGS. 5a and 5b is in the form of a ribbed edge portion arranged to be manually maneuvered by the user.

[0061] The suspensible device 102 further comprise a flat optical element 105 arranged adjacent to the light exit window 105.

[0062] In analogy with the above, when the suspensible device 102 is attached to the suspension element 111, a suspension angle is defined between the attachment surface 104 of the suspensible device 102 and the suspension element 111. The suspension angle has a first value when the balancing elements 107, 107 are in the first position, and a second value when the balancing elements 107, 107 are in the second position. In other words, the value of the suspension angle changes when the balancing elements 107, 107 are moved from a first position to a second position. The device system 101 of the present invention thus offers the advantage of providing a suspended device 102 that may be directed in different directions by moving the balancing elements 107, 107 between the first position and at least one second position.

[0063] The first position of the balancing elements 107, 107 may be defined as the position where the aperture 112 of the first balancing element 107 is aligned with the solid portion 113 of the second balancing element, and the solid portion 113 of the first balancing element 107 is aligned with the aperture 112 of the second balancing element 107. In such a position, the weight provided by the balancing elements 107, 107 is evenly distributed, thus causing the suspensible device 102 to point downwards such that the suspension angle is 90. The second position of the balancing elements 107, 107 may be defined as the position where the aperture 112 of the first balancing element 107 is aligned with the aperture 112 of the second balancing element, and the solid portion 113 of the first balancing element 107 is aligned with the solid portion 113 of the second balancing element 107. In such a position, the weight provided by the balancing elements 107, 107 is shifted, thus causing the suspensible device 102 to tilt such that the suspension angle is below 90. When the user wishes to change the suspension angle , he simply activates one or both of the actuating elements 108, 108 and rotates one or both of the balancing elements 107, 107 until a desired suspension angle is obtained.
