Definitions

  • the present device relates to a cover for a fan having a light source.
  • the ventilation unit which leads to an air duct is often installed on the ceiling or in a wall for providing forced ventilation .
  • the ventilation unit comprises an outer box-like housing, an electrically driven fan disposed within the housing, and a grill or fan cover attached to one side of the fan housing.
  • An air filter is often used to protect the ventilation equipment from dust. It is also common to control the operation of the fan via electronic equipment and to combine the fan with other electrical devices, such as a heater or a light source for room illumination.
  • the application provides a cover for a fan with an outer plate.
  • the outer plate is attachable to an inner plate via a connecting means.
  • the cover further provides a gap for the passage of air between the outer plate and the inner plate.
  • An LED panel is provided in the outer plate such that the LED panel is electrically connected to a power supply via the connecting means.
  • the application also provides a cover assembly comprising the cover for the fan and the inner plate with an air inlet, the outer plate of the cover and the inner plate being interconnected.
  • the LED panel which is used for illumination is thin compared with the overall thickness of the cover. This maintains the natural shape of the cover as an interior decoration and it is also an advantage over designs where the device protrudes downward from a ceiling.
  • the LED panel has low heat emission, therefore it will neither deform the ceiling material nor does it present a fire hazard.
  • the LED panel provides a uniform room illumination, not requiring further components for this purpose. However, if desired, the LED panel can be combined with other illumination sources such as light bulbs or neon tubes.
  • the LED panel usually has a longer life than an ordinary light bulb. Moreover, the LEDs in the LED panel can be connected in such a way that the other LEDs will continue to light if individual LEDs fail. Therefore, replacement of the LED panel is needed rarely or never during the lifetime of the ventilation unit.
  • the LED panel is integrated into the bottom of the cover. This design has a simple structure with only very few components. It is therefore robust and durable , especially when compared to the more complicated arrangement needed for a light bulb. No ad- ditional wires to the outer plate are required, as the LED panel is connected to a power supply via the connecting means.
  • the connecting means may comprise snap fits with a female part which is provided at one of the plates and with a male part which is provided at the other plate, the male part and the female part mating in a mounted state.
  • the inner plate and the outer plate are maintained at a predetermined distance for providing a gap for the air inflow between the inner plate and the outer plate. This can be achieved by the weight of the outer plate against the connecting means, by the form fit of the connecting means or by protrusions on one of the plates which serve as spacers.
  • the snap fits may be formed for maintaining the inner plate and the outer plate at a predetermined distance. They leave a gap for the passage of air between the inner plate and the outer plate.
  • T he female part of the snap fit may comprise two or more resilient arms.
  • the male part of the snap fit may comprise a base portion and a top portion.
  • the width of the top portion is greater than the width of the base portion.
  • the resilient arms of the female part are formed so as to enclose the top portion of the male part in an attached state.
  • the male part of the snap fit can also comprise a plug.
  • the plug has resilient arms with protruding ends.
  • the female part may comprise an opening, such that the resilient arms are locked into the opening by the form fit of the protruding ends.
  • a further type of snap fit has a pin with one or more grooves on its surface as male part and a female part with two or more resilient arms which fit into the grooves of the male part.
  • the connecting means comprises a hinge with an upper arm and a lower arm and an opening in the outer plate which takes up the hinge.
  • the upper arm of the hinge is connected to the inner plate and the lower arm of the hinge is connected to the lower end of the upper arm by a joint, such that the lower arm can be rotated about a horizontal axis.
  • the hinge also has a mechanism to fix the lower arm at a predetermined angle relative to the upper arm.
  • the connecting means may also be made up of a threaded bolt which is attached to the inner plate, an opening in the outer plate for receiving the bolt and a nut on the thread of the bolt.
  • the connecting means comprise a plug with protruding ends which is connected to one of the plates. Rotatable angles are provided on the other plate on the opposite side. The protruding ends of the plug fit into the space between the rotatable angles and the plate on which the angles are provided.
  • One way of assembling the LED panel into the outer plate is to integrate the LED panel into the center of the outer plate.
  • ventilation unit' refers to a fan housing with all parts contained in the housing, together with the aforementioned cover assembly.
  • T he ventilation unit or the cover assembly may be connected with two power supply terminals, one terminal for the LED panel and one terminal for the fan. Then the fan and the LED can be switched on and off independently.
  • a timer may switch off the fan a fixed time after the LED panel has been switched off.
