Definitions
- the invention relates to a lamp housing according to the preamble of claim 1 and an associated lamp.
- the invention has for its object a simple constructive Possibility to find the pressure equalization channel a lamp housing according to the preamble of the claim so to design that dust entering the channel from the outside and / or water are retained at least to a limited extent.
- a luminaire housing which is essentially airtight, with at least one pressure equalization channel, which the inside of the luminaire housing with the outside of the luminaire housing connects, and which is characterized in that the channel is sealed with an air-permeable membrane, which at least limits the passage of dust and water prevented.
- the membrane can be at one end of the Channel, but also in the channel itself, for example on attached to a shoulder or between two housing parts his.
- the Membrane a pore size of at most 5 microns, preferably at most 1 ⁇ m; in the particularly preferred embodiment of the Invention, the membrane has a pore size of less than 0.5 ⁇ m, e.g. 0.45 ⁇ m.
- the membrane on a wall section of the lamp housing glued.
- the membrane is preferably on one of the inside of the housing remote point attached to the thermal Reduce stress.
- the membrane preferably consists of a plastic film.
- a film with a polyester carrier fleece is particularly preferred and a polyether sulfone coating.
- the membrane is preferably at least below temperatures temperature resistant from 50 ° C and / or above - 10 ° C.
- the one used according to the invention was particularly preferred Membrane has a temperature resistance in a range of - 40 ° C to 120 ° C.
- a luminaire housing which, in the closed state at least the requirements for a dustproof luminaire in the sense of Standard EN 60598-1 (class IP5x) and / or at least the requirements to a water-protected luminaire in the sense of the EN standard 60598-1 (classes IPx1 to IPx6).
- the membrane on an outer, ie from the Opening of a bore facing away from the inside of the housing which forms part of the pressure equalization channel, and the section of the pressure equalization channel between the closed by the membrane and the mouth of the Pressure equalization channel to the outside of the luminaire housing and / or said bore is essentially straight.
- a lamp is also made available, which is a lamp housing as described above having.
- Luminaires are particularly affected by this Operation inside the case has a medium air temperature from 35 ° C to 110 ° C, especially high-performance lights with high pressure lamps, in the interior of the housing there is an average air temperature of more than 80 ° C, but also preferably used for indoor areas
- Luminaires for example with fluorescent lamps or low pressure lamps can be operated and typically an average air temperature of 50 ° C to 60 ° C during operation exhibit.
- the advantages of the invention are particularly evident with luminaires, the relatively high temperature fluctuations, either by switching the lamps on and off, be it due to environmental influences (e.g. cooling due to rain) and where typically a temperature difference between the mean air temperature inside and outside of the housing occurs in a range from 20 ° C to 100 ° C.
- Luminaires according to the invention can be used in the sense of the aforementioned Standard EN 60598-1 in the classes “dustproof” and fall “dustproof”. With the construction according to the invention luminaire housings can also be realized which are integrated into the Class of water-protected lights, especially the water-proof lights or the highly water-proof Luminaires in the sense of the standards mentioned above fall.
- the invention is a floodlight with a housing 1, the transparent front plate 3 over hinges 5 can be opened to the Access lamp 7.
- the housing is in the closed state essentially sealed airtight. That shows on the side Housing 1 has a mounting bracket 9, which is pivotable on the side walls the housing 1 is attached.
- FIG. 3 and 4 show the side of the Luminaire housing with front 3 folded away. Detected in Fig. 3 one a sealing groove 11 near the front edge 13th to accommodate an all-round seal (not shown). When the housing 1 is closed, a protruding one engages Edge of the movable front panel 3 (not shown) in the Groove 11 and causes together with the one located therein Seal a substantially airtight seal of the interior of the housing in which the lamp 7 is located.
- a blind bore 15 can also be seen, which extends to the outside slightly tapered and for attaching the mounting bracket 9 serves.
- a further rectangular recess 17 is provided which a straight connecting bore 19 in its bottom 20 with the Inside the housing 1 is connected.
- the outside of the housing facing mouth of the bore 19 is through a membrane 21 closed, which on the bottom 20 of the recess 17 is glued and the mouth of the bore 19 completely covered.
- This membrane has pores of one size on, which is a passage of air and water vapor into both Allow directions, but dust and / or water in liquid Hold back shape.
- the membrane 21 preferably consists of a polyester carrier fleece with a polyethersulfone coating and is double-sided breathable and waterproof. It has a pore size of approx. 0.45 ⁇ m and a thickness of approx. 125 ⁇ m. Typically it has a temperature resistance of - 10 ° C to 50 ° C, more preferably from - 40 ° C to 120 ° C.
- Such Membranes are known per se, but have so far been described in the lighting technology not used.
- a membrane that this Meets requirements, for example, is the self-adhesive Membrane 20-88 or 40-09 the carpenter's label and diklebetechnik GmbH & Co. KG, Oberschleissheim, Germany.
- Due to the small pore size of the membrane according to the invention is also the penetration of insects or their eggs and larvae prevented.
- the membrane according to the invention can be used without additional auxiliary construction especially in connection with a straight bore through the housing wall used to equalize the pressure serves. Pressure compensation devices according to the invention can therefore be realized with an extremely small footprint.
- the filter membrane can in any case existing information or guidance sign can be integrated.
- the lamp of the invention or the invention Luminaire housings are possible.
- 3 shows for example an embodiment in which the outer mouth the recess 17 closed by a protective cover 23 is which can be dust and water permeable and in essential the penetration of solid objects in the Recess 17, which lead to damage to the membrane 21 could prevent.
- This protective function can be used can also be achieved in that the mounting bracket 9 in the assembled Condition covers the recess 17.
- the location of the membrane can, depending on the type of lamp and its purpose another point of the pressure equalization channel between the inside and be attached to the outside of the housing. Instead of one single pressure equalization channel can be several by the invention Diaphragm-sealed bores or others Flow paths can be provided for pressure equalization.
- the invention can also be used in other areas.
- the invention can be used for dust-protected and / or water-protected housings for electrical components or equipment used in the operation of heating are exposed, e.g. for housings for ballasts, which then one with a membrane used according to the invention have closed pressure equalization channel.
- Another Possible applications of the invention are facets as reflectors for lights, especially reflectors for secondary lights. Such facets are for reasons of material savings often hollow and temperature fluctuations during operation exposed. The associated with these temperature fluctuations Pressure changes in the cavity may crack over time and to impair the function of the reflector facets to lead. This can be achieved through a pressure equalization channel between remedied the cavity of the facet and the outside become. This solution is in rooms without major dust and Water pollution already sufficient. However, if a dust and / or If there is water pollution, the pressure compensation channel, as described above, by an inventive used membrane are closed.
