Definitions

  • the invention relates to a lamp, in particular a lamp for lighting purposes.
  • the light can be designed in particular as an interior or exterior light.
  • WO 03/036159 A1 is a clean room light known, which has a frame and a reflector therein. Above the reflector solid-state light sources are arranged in the frame, which are mounted on a heat sink. The heat sink is adjacent to a cable channel with its upper side and is provided on its underside with a rib structure.
  • US 2012/0051058 A1 discloses a lamp in which a plurality of LEDs are arranged on a circuit board. Further, a transparent optical membrane is provided, which extends horizontally through the pear-shaped lamp. Electromechanical transducers drive the optical membrane to cause pulsatile up / down movement of the membrane. This creates an airflow that passes through slots in the board.
  • US 2006/0098440 A1 discloses a lamp with light-emitting diodes which are arranged on a circuit board. Furthermore, a system of replaceable lenses is provided which can be screwed onto a heat sink.
  • the post-published EP 2 525 145 A1 discloses a luminaire with active cooling.
  • the luminaire comprises a light module with a surface section which is in thermal contact with the luminous means, as well as a channel through which a cooling medium can flow.
  • An inner wall of the channel comprises the surface portion of the light module.
  • an active circulation device is provided for circulating the cooling medium.
  • nachveröttingte WO 2012/100022 A2 discloses a pear shaped lamp with a circuit board and one or more LEDs.
  • a heat sink is provided within the pear shaped housing which draws thermal energy from the LED using graphite based materials.
  • the DE 20 2010 004 868 U1 discloses LED bulbs on a tube-like cooling element.
  • the cooling element with the LED lighting means is arranged in a lantern-shaped or cylindrical housing and is cooled by means of a fluid flowing through and around the cooling element.
  • the DE 10 2009 031 613 A1 discloses a fluid convection heat dissipation device.
  • An LED carrier is integrated in a housing wall of a cavity in which a fluid circulates by convection and gives off heat to a housing wall having cooling fins.
  • the WO 2010/030063 A1 discloses a lighting device having a housing in which a fluid circulates by convection.
  • the housing is cylindrical and closed with a flat cover parallel to a lamp carrier inside the housing.
  • the object of the present invention is to provide a luminaire which allows a simple, efficient cooling of the luminous means.
  • the invention provides a luminaire, in particular an interior or exterior luminaire with a luminaire housing and a transparent cover, which define a cavity filled with fluid, in particular air, wherein an inner side of the luminaire housing which partially bounds the cavity is arched.
  • a support for at least one light source is accommodated, which has a first side for the arrangement of the at least one luminous means and an opposite second side.
  • the carrier is arranged inside the cavity such that heat generated by the at least one light source and conducted through the carrier to the second side can be dissipated by convection of the fluid at least partially to the inside of the light housing.
  • the cavity includes any fluid that may be used for convection, for purposes of simplicity of description, it will be assumed hereinafter that the cavity is filled with air. However, those skilled in the art will recognize that the cavity may alternatively or additionally also be filled with another fluid, in particular with another gas.
  • the lighting means is in good thermal contact with the carrier.
  • the heat generated by the light source is delivered to the carrier via the first side.
  • the heat reaches its second side, where it is released to the surrounding air.
  • the carrier is arranged inside the cavity of the luminaire in such a way that the air located above the second side of the carrier can transport the heat away from the carrier by means of a convection process. In this way, the heat generated is at least partially dissipated to the lamp housing. This allows efficient cooling of the lamp, without the need for other, in particular active components, such as a fan or a circulation pump. Further, according to the invention, no further coolant, such as e.g.
  • the first and / or the second side of the carrier may be at least partially smooth and / or flat, so that the fluid can flow unhindered over the first or second side.
  • the first and / or the second side of the carrier is unstructured and in particular does not have cooling structures, such as e.g. Cooling fins on.
  • the support, in particular on the second side may be provided with cooling fins.
  • the inside Due to the curvature of the inside, this has a larger surface area, so that the heat can be efficiently delivered to the luminaire housing and the cooling effect is improved.
  • the inside can in particular be curved inward or outward and / or bell-shaped.
  • the luminaire can be designed, in particular, as a trough luminaire, recessed or surface-mounted luminaire, pendant luminaire, floor lamp, ceiling or wall luminaire.
  • the luminaire can be designed as an outdoor luminaire, preferably as a decorative outdoor luminaire. It is preferred that the lamp is arranged so that in the mounted state of the lamp, an air flow over at least a portion of an outer side of the lamp housing, in particular in the region of the cavity is made possible. In this way, the heat generated by the lamp can be effectively delivered through the lamp housing to the environment.
  • the light-emitting means may in particular be a group of LEDs (light-emitting diodes) or OLEDs (organic light-emitting devices).
  • the transparent cover has means for directing light, for example a prism structure and / or a lens structure.
  • the means for directing the light can be formed on the cover or arranged as separate components on the cover.
  • the means for directing the light can be arranged on an outer and / or an inner side of the cover.
  • the luminaire housing does not necessarily have to be made of a material with particularly high thermal conductivity, in particular when using bulbs with low heat generation. This allows the designer to select the material in other ways, especially in terms of space requirements, weight or design.
  • the lamp housing can be made of plastic.
  • the light housing may be made of metal, for example, aluminum. In this way, the heat can be better dissipated from the inside of the lamp housing to the outside and the lamps are cooled more efficiently. This is particularly advantageous for bulbs with high heat generation and / or small volume lights.
  • the housing is made of sheet metal, so that the heat can be dissipated easily to an outside of the lamp housing.
  • the transparent cover may be made of a transparent plastic, in particular of polymethyl methacrylate (PMMA) or of glass.
  • PMMA polymethyl methacrylate
  • the cover and the luminaire housing may be attached to each other, e.g. by means of a screw, latch or bayonet connection.
  • the luminaire has further components, for example light-directing means such as a reflector or lenses, and / or a power supply.
  • light-directing means such as a reflector or lenses
  • / or a power supply One or more of the ingredients may be incorporated into the cavity. It should be noted, however, that the cooling of the carrier by means of convection is still possible.
  • the luminaire housing has a greater distance to the carrier over a central region of the carrier than over a peripheral region of the carrier. In this way, a greater distance to the lamp housing is achieved over a central region of the carrier. This improves the convection. This is particularly advantageous when the lighting means is arranged at the central region of the carrier. Furthermore, it can be provided that the luminaire housing is arched over the carrier like a fireplace to the outside. This further improves the cooling.
  • the transparent cover has a greater distance to the carrier over a central region of the carrier than over a peripheral region of the carrier. Similar to the luminaire housing, this embodiment of the cover improves the convection within the cavity below the carrier and thus provides improved cooling.
  • an inner side of the transparent cover which partially delimits the hollow space is arched over a central region of the support and can in particular have a shape of a tub or a shape of a hollow sphere cutout, preferably a hemisphere.
  • This causes a larger surface area of the inside of the cover, so that heat can be efficiently delivered to the cover.
  • This is especially preferred when the convection also detects a portion of the cavity defined by the cover, e.g. in that the carrier has through-holes or defines a gap with a border of the cavity.
  • the carrier is designed as a carrier plate.
  • the carrier is flat. This allows the fluid to flow freely over the carrier plate, whereby the convection is further improved.
  • the second side of the carrier is in particular not convexly curved.
  • the luminaire housing and the cover abut each other along a plane, the carrier preferably being arranged along the plane.
  • the luminaire housing and the cover can be connected to each other in particular along the plane.
  • the concern and in particular the connection of the luminaire housing and the cover along a plane facilitates the mounting of the cover to the luminaire housing.
  • the arrangement of the carrier along the plane makes it easy for a fitter to reach after the transparent cover has been removed. In this way he can easily replace the bulb. Furthermore, this causes a central arrangement of the carrier in the cavity, so that in particular to the lamp housing is sufficient distance to allow efficient convection.
  • the lamp further comprises one or more arranged on a board or on a module lamp, in particular a group of LED and / or OLED, wherein the board or the module on the first side of the carrier and in thermal contact with the Carrier, in particular by means of a thermal paste, a thermally conductive adhesive or a planteleitfolie is attached.
  • the arrangement on a board or a module allows easier mounting of the light source to the carrier.
  • the carrier may be made of a metallic material without fear of short circuits of the lighting means. A good thermal connection of the board or the module to the carrier is preferred, since the heat generated by the lamp is dissipated from the board or the module to the carrier.
  • the module may further comprise a cover, by which the lighting means is at least partially covered.
  • the lighting means may e.g. be arranged laterally on the module and / or in the module.
  • the carrier may in particular be made of plastic or of metal, in particular of aluminum, steel or copper. These materials are preferred because they have high thermal conductivity so that the heat is efficiently conducted from the first to the second side of the carrier.
  • the optimum thickness of the carrier depends on various factors, such as the shape and material of the lamp housing, the carrier and the board. Too small a thickness limits the dispersion of heat within the carrier, so that the heat is insufficiently distributed over the second side of the carrier. However, if the thickness is too high, the air is heated over the entire second side of the carrier so that there is a large buoyancy force of the air molecules everywhere, making it difficult to circulate the air in the cavity.
  • the support may have a thickness between 1 mm and 20 mm, in particular between 1 mm and 12 mm, preferably between 2 mm and 10 mm and particularly preferably between 4 mm and 8 mm ,
  • the carrier fills a cross section through a cavity.
  • the carrier extends through the entire Cavity, so that a particularly large surface area on the second side of the carrier for the delivery of heat and for generating the Konventionstromes available.
  • At least one gap sized to allow passage of fluid in the cavity between an area above the second side and an area above the first side of the carrier is defined between the carrier and a rim of the cavity.
  • the convection senses the entire cavity on both sides of the carrier. This allows a better distribution of the heat generated by the bulb in the cavity. Furthermore, in this way, the heat can also be delivered to the transparent cover, so that its outer side also contributes to the release of heat to the surrounding air.
  • the gap is a gap circulating around the carrier. This embodiment allows the fluid to pass from one side of the carrier to the other over the entire circumference of the carrier. Convection within the cavity is thus improved.
  • the carrier may have one or more through-openings to allow passage of fluid from one side of the carrier to another side of the carrier. This improves the heat distribution within the cavity.
  • Through openings in the carrier are particularly advantageous in connection with a gap, since the fluid flowing down through the gap can flow back up through the through openings.
  • the passage openings and / or the at least one gap may be round and / or angularly shaped.
  • the carrier is arranged within a subregion of the cavity defined by the luminaire housing.
  • the carrier is protected by the lamp housing. This is preferred over other embodiments in which the carrier is arranged within a subregion defined by the transparent cover.
  • the carrier does not protrude during assembly when the cover is removed, so that accidental damage can be avoided.
  • the luminaire housing and the cover seal the cavity to the outside.
  • the luminaire housing and the cover can insulate the cavity from the outside so that dust or moisture can not penetrate therein.
  • the carrier, the lighting means and possibly located in the cavity electronic components is protected.
  • FIG. 1 shows a lamp with a bell-shaped lamp housing 2 and an attached hemispherical transparent cover 3.
  • the lamp housing 2 and the cover 3 include a cavity and surround it completely.
  • the luminaire housing 2 and the transparent cover 3 are connected to one another along an annular line which defines a plane in which a carrier 5 is arranged.
  • the carrier 5 is in the in FIG. 1 illustrated embodiment as a separating plate between a defined by the lamp housing 2 portion of the cavity and a defined by the transparent cover 3 portion.
  • the carrier 5 separates these two sections completely from each other.
  • the carrier 5 is connected at its edge to the lamp housing 2.
  • a board 4 with a plurality of LED as the light source On a first side of the carrier 5 (bottom in FIG. 1 ) is arranged a board 4 with a plurality of LED as the light source. During operation, the LEDs generate heat, which is delivered via the board 4 to the carrier 5. The heat is within the carrier 5 from the first side to an opposite, the lamp housing 2 facing the second Page directed. As a result, the air located above the second side of the carrier 5 is heated, so that convection begins and an air flow is generated, as illustrated in FIG. 1 by means of the arrows provided with reference number 6.
  • the bulbs in particular heat a region of the carrier 5 in an environment of the circuit board 4.
  • the air heated there over the second side rises and reaches the luminaire housing 2. There, the air releases some of its heat to the luminaire housing 2 and flows to the Sides of the luminaire housing 2 back downwards in the direction of the carrier 5.
  • FIG. 1 A partition 7 in the luminaire housing 2 is shown above the carrier 5.
  • the partition 7 is arranged parallel to the carrier 5.
  • the partition 7 prevents too much rising of the heated air during the convection process. In this way, the convection movement of the air can be adjusted in order to achieve optimum release of heat to the luminaire housing 2.
  • FIG. 2 a further embodiment of a lamp with a bell-shaped lamp housing 2 and a hemispherical transparent cover 3 is shown.
  • the carrier used 5 This fills in FIG. 2 not the complete cross section through the cavity. Rather, a circumferential gap 8 is formed between the carrier 5 and the border of the cavity defined by the luminaire housing 2.
  • the carrier 5 has a plurality of angular through openings 9. Through the gap 8 and through the passage openings 9, air can circulate between a portion above the support 5 and a portion below the support 5 within the cavity. In particular, the air cooled on the luminaire housing 2 flows through the gap 9 into the subregion of the cavity defined by the cover 3.
  • the cover 3 There she reaches the cover 3 and gives another part of the heat to this. Subsequently, the air flows through the through holes 9 back into the upper portion of the cavity, which is defined by the lamp housing. Through the gap 8 and the openings 9, the heat can be better distributed in the cavity and be delivered except to the lamp housing 2 and the transparent cover 3. In this way, a larger area of the outer surface of the lamp is available for heat dissipation.
  • the light can be used in particular with a 50 W light source.
  • the luminaire housing made of plastic be made. Due to the bell shape of the luminaire housing 2, the heat is emitted over a large area to this, so that no particularly good heat conducting material such as aluminum is required. In this way, the production cost of the lamp can be lowered and the lamp is easier to manufacture.
  • a thickness of the carrier 5 in the region of the board between 4 mm and 8 mm is sufficient, wherein the carrier 5 is made of aluminum.
  • the luminaire housing and / or the cover can be trough-shaped.
