Definitions

  • the present invention relates to a light module for an exterior light and an exterior light comprising at least one light module.
  • Outdoor and outdoor lighting modules are commonly used to illuminate an outdoor area, for example in street lamps.
  • Known light modules often have board receptacles and boards arranged therein, which have at least one light source.
  • the light bulb is for example a classic light bulb or a modern LED.
  • elaborate devices are made for the sealing of the interior.
  • it must be avoided that in outdoor lights that are exposed to strong weather, an impairment of the arranged on the board electronics.
  • LEDs as lighting means such a seal is of great importance.
  • a corresponding watertight housing is provided for this purpose, which brings with it the corresponding necessary shielding.
  • a disadvantage of such embodiments is that the tightness of the housing often also produces airtightness.
  • US 2011/0051423 describes an LED module with an SMD LED, which is arranged as usual on a circuit board. Above the LED is a dome-like translucent cover, which is supported on the board and the side of a protective layer connects, which protects the board from moisture and hermetically seals the gap between the cover and the board.
  • a protective layer connects, which protects the board from moisture and hermetically seals the gap between the cover and the board.
  • the dome In the dome is an opening through which neither water nor air in the space formed by the cover from the environment can penetrate. About the opening only dangerous gases can escape from the interior to the environment.
  • the opening is designed as a narrow channel, which is filled with a plastic.
  • DE 10 2009 019 226 A1 shows an LED lamp with a housing having a cooling channel, which is thermally connected to an LED unit disposed in the housing.
  • a cooling air flowing through the cooling channel is generated by a fan so as to cool the LED unit.
  • the cooling air duct is protected by a semi-permeable membrane against the ingress of moisture or dust.
  • JP2006080095A discloses a lamp having a housing which is closed forward of a translucent cover. In the housing sits in a step a board with a plurality of LEDs. The housing has ventilation holes that are closed with a porous waterproof material.
  • JP2010009959A shows a lamp with a housing having an airtight space.
  • a ventilation part has ventilation openings in front of which a filter is arranged, which allows an exchange of air between the ventilation part and the environment, but not the ingress of water into the ventilation part.
  • Between the airtight space and the ventilation part is a porous film which yields when a pressure difference is exceeded and then allows an exchange of air between the environment and the otherwise airtight space through the ventilation openings.
  • CN201396638Y describes an LED lamp with a lamp body having in its side walls ventilation openings which are closed by a waterproof air-permeable membrane.
  • CN201787544A describes an LED lamp with a tubular housing.
  • the housing In order to allow pressure equalization between the interior of the housing and the environment, the housing has ventilation openings which are covered by air-permeable and at the same time waterproof membranes.
  • KR20090100922 discloses an LED lamp in which LEDs are mounted as usual on a circuit board. To dissipate the heat, the LEDs are thermally connected to a heat sink, which is vented through the housing openings.
  • US 3,337,480 discloses a gas discharge lamp with a housing.
  • the housing accommodates the lamp between a housing bottom and a housing cover.
  • In the housing base and in the housing cover are openings, so that air can enter through the housing bottom, there to heat and escape upwards. This results in a convection cooling.
  • the opening in the housing cover is bounded by an annular inwardly facing flange. In this opening sits a cup-shaped receptacle for a sensor, wherein the edge of the receptacle protrudes to cover the upper vent opening so that it does not rain into the housing.
  • US 3,092,336 discloses a street lamp with a housing of a metallic shell and a translucent base.
  • the upper part can be attached to a lamppost or a building.
  • the lower part is clamped by means of clamping closures against the upper part, wherein between the upper part and the lower part of a circumferential seal is arranged, which prevents ingress of moisture into the closed housing.
  • the upper housing part engages over the circumferential seal, probably to protect against driving rain and sun rays, which can lead to accelerated aging of the seal.
  • the lower housing part can be easily opened.
  • DE 200 13 212 discloses a neon sign with a liquid-tight housing.
  • the housing has an opening in a side wall which is covered by a vapor permeable membrane.
  • a light module and an outdoor lamp are provided, which are at low cost and simple design in a position to allow pressure equalization between the interior and the environment and at the same time bring the necessary electrical safety.
  • a light module according to the invention for an exterior light has a board receptacle and at least one circuit board arranged in the circuit board receptacle.
  • the circuit board in turn is equipped with at least one light source, in particular in the form of an LED (Light Emitting Diode).
  • a cover is provided, which covers the board receptacle and the board arranged therein liquid-tight. This liquid-tight cover is often also airtight at the same time, so that a pressure equalization over this tight barrier is not possible.
  • the cover itself has a lens that is translucent to allow the light generated by the bulb through.
  • the cover is preferably aligned in a manner that the path of the light is released in a direction that allows the necessary illumination of the environment of the outdoor lamp.
  • Inventive light modules are preferably to be used so that they can be reversibly positioned in an outdoor lamp. This serves to ensure that the light module is replaceable in an existing outdoor light in a simple and cost-effective manner.
  • An inventive light module is characterized in that in the cover at least one ventilation opening is arranged, which with an air-permeable and liquid-blocking balancing membrane is covered.
  • the ventilation opening can be provided at least in the cover, but in particular in the cover plate itself.
  • the ventilation opening and, accordingly, the compensation membrane are arranged at other locations, for example in and on an opaque frame portion of the cover.
  • An air-permeable and liquid-blocking compensating membrane in the context of the present invention is, in particular, a component which has a substantially thin or flat extension.
  • the compensation membrane is preferably at least partially elastic or flexible.
  • Fluid-barrier and permeable to air, the compensating membrane may for example be designed in that it is provided with pore sizes, the drop sizes of conventional liquids, such as water, salt water or similar liquids, not through, while air can pass through this balancing membrane unhindered.
  • Such membranes may also be referred to as breathable waterproof materials and are preferably to be used for a balancing membrane according to the invention.
  • the compensation membrane covers the at least one ventilation opening.
  • the compensation membrane with respect to the cover cross-section projects beyond the ventilation opening on one or more sides or even completely. This improves on the one hand the liquid-blocking seal and on the other hand it facilitates the attachment of the compensation membrane at the desired position.
  • Using an LED in a light module according to the invention has the advantage that the temperature fluctuations are reduced. Accordingly, at temperature differences between the off state (20 ° C) and the on state (70 ° C) only a smaller Temperature difference and, accordingly, a lower pressure difference between the inner region and the outer region of the light module effectively.
  • the ventilation opening itself is in particular a simple bore, which has been produced for example by the machining in the cover. If the cover is produced by a casting method, in particular by an injection molding method, the ventilation opening or the multiplicity of the ventilation openings can already be taken into account during the casting process by the correspondingly formed casting mold.
  • the board receptacle and the board in the context of the present invention may be integrally formed, in particular in one piece or monolithic.
  • a circuit board is to be understood as meaning a component on which a multiplicity of interconnects are arranged, which interconnect the individual illuminants or connect them to a connection for the illuminants.
  • the board is used in particular for the supply of lighting with electricity.
  • the board may also have a control device to regulate the brightness of the lamps or, for example, their color.
  • the board receptacle is preferably made of a stiff, mechanically stable material.
  • a stiff, mechanically stable material is for example aluminum die casting. This has the advantage that the mechanical stability is achieved by a cost-effective method and at the same time with very light weight.
  • a light module according to the invention can be further developed such that the compensation membrane has a lifting protection against the removal of the position covering the at least one ventilation opening.
  • This lifting protection serves to prevent unintentional removal of the compensation membrane. It serves, for example, in the form of a hold-down, in particular that the edge region of the compensation membrane can not be raised. It is particularly important to turn off the necessary cleaning of such a light module or an outdoor light. If such an outdoor light is cleaned, for example, with a high-pressure radiator or a steam jet, the lifting protection, in particular at the edges of the compensating membrane, serves to prevent ingress of high-pressure liquid at the edge of the compensating membrane. Thus, a lifting and thus a tearing of the compensation membrane are avoided by the desired position.
  • the compensation membrane is at least positively connected to the cover.
  • a frictional connection can be designed in particular as a material connection.
  • the compensation membrane is connected to the cover, for example by means of adhesive or other cohesive methods.
  • non-positive connection options such as by screws or by clamping are conceivable within the scope of the present.
  • non-positive connection for example by screws or clamping, easy disassembly of the compensation membrane possible.
  • a single compensating diaphragm is easily interchangeable, even if the remainder of the light module is still functional.
  • the provision of an adhesive or other irreversible means for a cohesive connection between compensating membrane and cover has the advantage that even wanton removal is difficult or impossible at all. The functionality security of the light module is increased in this way.
  • the life of the compensation membrane is greater than or equal to the life of the at least one board and / or the at least one light source.
  • the service life of the compensation membrane, the life of the board or the at least one illuminant is functional.
  • the compensation membrane has a longer service life than is the case with the circuit board and / or with the luminous means. It can thus be ensured that the essential function, namely the illumination, can become shorter than the secondary function, namely, the compensation function of the compensation membrane.
  • a compensation membrane is available, which has a corresponding resistance in particular with regard to the weather resistance.
  • the lifetime of a component is to be understood as the reduction in functionality. In particular, the reduction in functionality as the end of the service life is less than 50%, or less than 60% or less than 70% of the original, new functionality.
  • the cover has a drip edge, which surrounds the compensation membrane at least in sections and prevents water, which runs along the cover, from the compensation membrane.
  • a drip edge which surrounds the compensation membrane at least in sections and prevents water, which runs along the cover, from the compensation membrane.
  • the drip edge is in the context of the present invention, a component which brings a dripping and / or complete redirecting the oncoming liquid with it. This water accumulation on the membrane are avoided or reduced to a minimum.
  • the compensation membrane is arranged on the inside of the cover which faces the circuit board. In other words, an interior is formed between the cover and the board receptacle, in which the compensation membrane is arranged. This leads to an even better protection of the membrane against the effects of weather as well as against additional mechanical interventions as they occur, for example, in cleaning situations of the outdoor lamp.
  • the assembly is somewhat more complex than an external compensation membrane, but in this way the compensation membrane itself can be made even more cost-effective and, for example, thinner.
  • compensation membrane is arranged on the outside of the cover, which is averted from the board.
  • This is the opposite embodiment to the embodiment described above.
  • these two variants can be combined at different points even when using different balancing membranes.
  • the provision of an external compensation membrane brings with it easier assembly and moreover increases the visibility of defects on the compensation membrane. If this is injured, this is visible from the outside.
  • an exchange of the same is possible from the outside for such a compensation membrane arranged.
  • the at least one ventilation opening is arranged in such a way that the compensation membrane in the direction of the installation of the light module in an outdoor lamp or essentially pointing in the direction of gravity. In a usually radiated from top to bottom outdoor light, this also means that the compensation membrane is directed downward. In such an outdoor lamp, it is possible to design the compensation membrane again cheaper and easier, because it is partially removed from the direct weather. In particular, rain, which falls from top to bottom, is held by the outdoor light itself or by other components of the light module. Direct exposure of raindrops or even hailstones to the balancing membrane is thus minimized.
  • the compensation membrane is arranged at a position which is outside or substantially outside of a light cone, which is generated by the at least one LED.
  • the compensation membrane is provided in the cover plate in the cover, such an arrangement is useful. As a result, shading by the membrane is avoided or reduced.
  • the compensation membrane is located in an edge region of the cover disk or in an edge region of the cover, which may be formed, for example, as a mechanically stabilizing frame.
  • connection means are, for example, snap-latch connection means. Alternatively, screws or clamps or riveted joints are possible.
  • connecting means are designed as reversible connecting means, so that the light module can be reversibly placed in an outdoor light and removed from it again.
  • the light module can be seen as a replacement or wearing part, so that in case of failure of one or more bulbs, the entire light module is interchangeable.
  • an outdoor luminaire comprising at least one light module according to the invention. It is particularly important to pay attention to the orientation of the compensation membrane, which is preferably in the direction of gravity, that is, for example, in an outdoor light down, arranged. Accordingly, an outdoor luminaire according to the invention brings with it the same advantages as have been explained in detail with reference to a light module according to the invention.
