Definitions

  • the present invention relates to a light fixture comprising a head, which head is rotatable in relation to a U-shaped yoke by at least a first motor, the head being disposed between two legs of the yoke, which yoke is rotatable in relation to a base by at least a second motor, which head comprises at least one light source for generation of a light beam, which base comprises at least a power supply and a controller for control of the light fixture, which yoke comprises handles for carrying the light fixture.
  • Carrying a light fixture is an increasing problem when the physical size of light fixtures is increasing. Therefore, handles are placed at the base or at the yoke which is well-known from a number of light fixtures such as light fixtures from Martin Professional A/S.
  • Light fixtures comprising handles formed as recesses in the yoke are well-known. These handles are placed below the rotational centre of the head and are efficient for small light fixtures that can be carried by an individual. In a situation where a head is not locked or motion damped the head might move during carrying which can lead to movement of the gravitational centre of the light fixture which can result in the light fixture being dropped.
  • a further object of the invention is to place handles for carrying a light fixture at the upper part of the yoke over the gravitational centre of the light fixture.
  • the object of the invention can be fulfilled by a light fixture as described in the preamble to claim 1 and modified by letting at least one handle extend from the upper part of the yoke such that the handle extends from a free end of one of the legs of the yoke.
  • the handle can be placed above the rotating centre for the head. Hereby, it is achieved that if the head starts rotating, this will take place in a position below the handle. In most cases, rotation of the head will not take place as the head is locked when the light fixture is carried. But even in situations where the head has not been locked, carrying the light fixture is possible if the handle is placed above the rotating centre.
  • the handle can be placed above the centre of gravity of the light fixture.
  • the positioning of the handle above the centre of gravity leads to a situation where the light fixture is very stable when it is carried by the handles.
  • the handle can be placed at the top of the yoke and the handle is extending upwards in relation to the head.
  • the handles By letting the handles extend upwardly, it is possible to reach a point of carrying that is somewhat over the top of the yoke. This is positive in achieving a larger distance in relation to the rotating centre for the head and also in relation to the centre of gravity.
  • the higher the handles are placed above the yoke the more efficient the handles will be in use.
  • the handle can be placed at the top of the yoke extending outwards in relation to the head. Letting the handles extend outwards will provide easy access for a hand into the handle. Increasing the distance between the handles will also increase stability when carrying the light fixture.
  • the base can comprise at least one handle. Placing additional handles on the base could be very useful if the light fixture is to be carried or placed in operation.
  • FIG 1 shows a schematic side view of a light fixture cable of producing a light beam (3).
  • the light fixture 2 comprises a base 4 and a yoke 6.
  • a head 8 is placed in the yoke.
  • the yoke 6 comprises handles 10 and 12.
  • the base 4 comprises handles 14 and 16.
  • this line indicates the line of gravity 18 for the base.
  • centre of the head 8 is indicated as centre of gravity 20 and rotation centre (22) around which the head can rotate.
  • the head is often constructed such that the centre of gravity (20) of the head is positioned near or at the rotation centre (22)
  • Figure 2 is a schematic side view of a light fixture 2.
  • Figure 2 shows the base 4, the yoke 6 and the head 8. Only one of the handles 10 is seen.
