Definitions

  • the present disclosure relates to a light fixture, and especially an arrangement for facilitating mounting and maintenance of a light fixture.
  • a light fixture comprising a base frame extending longitudinally along a first axis, a translucent cover arranged to the base frame and at least one gable.
  • the light fixture is characterized in that the at least one gable is rotationally moveable around a second axis relative to the base frame between an open position and a closed position, such that the translucent cover is fixed relative to the base frame by the at least one gable being in the closed position, and that the translucent cover is removable from the base frame when the at least one gable is in the open position.
  • the at least one gable can be rotated from an open position to a closed position and when in the open position allows for the translucent cover to be removed without use of force or tools that may cause damage to the translucent cover. Further, after mounting of the light fixture, maintenance of the light fixture may be performed by simply rotating the gables into the open position and removing the translucent cover.
  • the base frame provides support and rigidity to the light fixture as well as that it provides an area for mounting the light fixture to a ceiling, wall, or other suitable surface.
  • the translucent cover may be translucent or transparent to spread light over an area or direct light in a certain direction.
  • the other gable may in such embodiment be fixedly attached to the base frame, or be provided as an integrated portion of the base frame. Only one rotatable gable may provide a simpler and more cost-efficient fixture, with kept functionality of removability of the translucent cover.
  • the first axis of the base frame may be perpendicular to the second axis of the base frame.
  • the first axis provides the axis of extension of the base frame and the second axis provides the central axis of rotation for the gable.
  • the second axis may further be located on a longitudinal end of the base frame.
  • a hinge may be arranged to the base frame, wherein the gable is suspended to the base frame by the hinge, and wherein the hinge provides the rotatability of the gable around the second axis.
  • the hinge may be arranged at a distance from a side portion of the base frame, where the side portion extends in a direction parallel to the second axis, such as to form a space between the gable and an outer side of the side portion.
  • Arranging the hinge at a distance from the side portion moves the axis of rotation of the gable further along the first axis which provides a space between the side portion and the side of the gable facing the side portion.
  • Such space may be useful for arrangement of fixture components, such as cables received by the fixture.
  • the side portion may further extend in a direction perpendicular to the first axis.
  • the hinge is arranged at a distance from an outer surface of the side portion, which outer surface faces an inner side of the gable.
  • the gable may be rotatable at least 5 degrees, preferably between 5-45 degrees, more preferably between 5-25 degrees, most preferably between 5-15 degrees, around the second axis between the closed position and the open position. The rotation of the gable provides space for the translucent cover to be released from the base frame.
  • the at least on gable may extend in the direction of the first axis such that an end portion of the translucent cover is held fixed relative to the base frame when the at least one gable is in the closed position.
  • the gable may extend from one longitudinal end of the base frame towards the other longitudinal end of the base frame such that a portion of the translucent cover is covered by the gable and held into position such that the translucent cover may be prevented from falling off or being removed by other means from the base frame when the gable is in the closed position.
  • the end portion of the translucent cover may rest on a holding portion of the gable, when the gable is in the closed position.
  • the base frame may comprise a first and a second side portion extending in a direction parallel to the second axis.
  • the first and second side portions may comprise an outer side facing the gable and an inner side facing an interior of the base frame.
  • the translucent cover may be configured to extend between the inner sides of the first and second side portions, and the gable may comprise a holding portion which in the closed position may be configured to extend past the first and second side portions in direction from the outer side to the inner side thereof to hold the end portion of the translucent cover.
  • the first and second side portions may provide a barrier between the space between the gable and the side portion and the space of the interior of the light fixture.
  • the first and second side portions may further provide support and an area of attachment to the base frame for the hinge.
  • the first and second side portions may further extend in a direction perpendicular to the first axis.
  • the base frame may comprise a third and fourth side portion extending along the longitudinal direction of the base frame.
  • Each of the third and fourth side portion may comprise an outer side facing the exterior of the base frame and an inner side facing the interior of the base frame.
  • the translucent cover may be arranged to abut the inner side of the third and fourth side portion respectively.
  • the third and fourth sides together with the first and second sides of the base frame may form a rectangular shape which construct the base frame.
  • the abutment between the translucent cover and the third and fourth sides may serve to suspend the translucent cover to the base frame when the gable is in the open position such as to prevent uncontrolled removal of the translucent cover or that it falls or loosens from the frame in an uncontrolled manner.
  • the light fixture may further comprise a base side arranged between the first through fourth sides and opposite the translucent cover.
  • the base side may be configured to be fastened to a ceiling or wall or other suitable surface to which to arrange the light fixture.
  • the holding portion of the gable may extend past the first and second portions and may extend such that it extends past the first and second side portions and covers part of the third and fourth sides and the end portion of the translucent cover while leaving the base side uncovered such as to allow for rotation of the gable without limitation or disturbance from the back side of the base frame.
  • the at least one gable may be held in the closed position by means of attaching means.
  • the attaching means may serve to keep the gable in the closed position such as to prevent unintentional rotation of the gable into the open position and thus preventing the translucent cover from falling off or getting loose unintentionally.
  • the attaching means may provide that a force above a threshold force level is required in order to move the gable to the open position.
  • the attaching means may comprise at least one first attaching member and at least one second attaching member configured to adhere to each other.
  • the first and second members may adhere to each other when the gable is in the closed position and may be non-adherent when the gable is in the open position.
  • One of the attaching members may be arranged on the gable, and the other one on a side portion of the base frame.
  • one of the attaching members may be arranged on an inner side of the gable, facing the side portion, and the other attaching member may be arranged on an outer side of the side portion, facing the gable.
  • the at least one first and at least one second attaching member may correspond to a at least one first and a at least one second magnetic member respectively.
