Definitions

  • the present invention relates to a linear luminaire, in particular a moisture-proof luminaire, the extent of which in the longitudinal direction is significantly greater than in another spatial direction.
  • the lamp comprises a lamp base body and an at least partially translucent lamp housing in which a lamp is arranged.
  • the lamp housing is pivotably connected to the lamp base body, in particular by means of at least one flange, the lamp base body and lamp housing each being tubular and elongated.
  • a damp-proof luminaire which leads connection cable for a discharge lamp sealed out of a luminaire body by means of a pierced plate.
  • the CN 204 437 792 U teaches a light with a motion detector, which comprises two pivoting headlights.
  • the DE 20 2015 009 424 U1 discloses a linear luminaire according to the preamble of claim 1.
  • the FR 2 603 091 A1 also discloses a linear luminaire.
  • the challenge is to permanently seal the damp-proof luminaire against moisture in the environment or even against spray and pressurized water.
  • seals must be attached at the transition points between the various parts of the luminaire.
  • annular seal is usually provided which allows pivotability.
  • this annular seal is inserted into a semicircular recess in conventional luminaires, for example, with a closure cap then is attached with a semicircular recess on the lamp base body in order to attach the lamp housing to the lamp base body. The seal is then held between the two semicircular recesses.
  • an additional seal is provided in the closure cap, which is not circumferential but instead rests against the annular seal at two points in order to seal the connection between the closure cap and the main body of the lamp.
  • the object on which the invention is based is therefore to provide a lamp and, in particular, a damp-proof lamp, the lamp housing of which can be pivoted, but with a high and permanent security against the ingress of moisture.
  • connection between the lamp housing and the lamp base body is made by means of a pressure cover, the pressure cover having a circumferentially sealed first connection to the lamp housing and additionally a circumferentially sealed second connection separate from the first connection Has connection with the lamp body.
  • two connections sealed all around are used.
  • Such all-round sealed connections can be made with high process reliability. This means that there is no need to use a non-circumferential seal, as is the case with conventional damp-proof luminaires. A position where "seal on seal" meets can therefore be avoided.
  • the two connections that are circumferentially sealed according to the invention create a permanently reliable seal against penetrating moisture. The reliability of the lamp according to the invention can therefore be significantly increased.
  • the lamp according to the invention allows very simple assembly.
  • the pressure cover can create a rotatable and at the same time tight connection with the lamp housing and also a permanently tight connection with the lamp base body. This makes it possible to attach the pressure cover to the lamp housing prior to final assembly, so that only the second connection with the lamp base body then has to be established during final assembly.
  • the flange which connects the lamp base body and the pressure cover, is preferably circular in cross section in order to ensure the pivotability of the lamp housing (relative to the pressure cover).
  • the flange can in particular be designed as a hollow cylinder and also as a pin.
  • the lamp is preferably a moisture-proof lamp.
  • the luminaire can, for example, meet protection class IP65, IP67, IP68 or higher.
  • the lamp is a linear lamp, i.e. the length of the lamp in the longitudinal direction is significantly greater than in another spatial direction.
  • the lamp base body and the lamp housing are each tubular and elongated. Both can be made from plastics, in particular from a thermoplastic or a thermosetting plastic.
  • An operating device can be arranged within the lamp base body.
  • the operating device is, for example, a switching converter that converts a line voltage into an operating voltage or an operating current for the lighting means.
  • the lighting means can preferably be formed by one or more LEDs (light-emitting diodes).
  • the LEDs can for example be arranged on a circuit board or other suitable carrier.
  • the first connection comprises an annular first seal, the first seal preferably being arranged between the flange and the illuminant housing or between the flange and the pressure cover.
  • the flange can either be part of the pressure cover or the lamp housing.
  • the first seal can be located between the flange and the lamp housing.
  • the ring-shaped first seal makes it possible to pivot the lamp housing, in particular about the flange.
  • the second connection comprises a, preferably essentially rectangular, second seal, which is arranged between the pressure cover and the lamp base body.
  • the second seal can also comprise other shapes that do not allow rotatability or pivotability, since such a pivotability between the pressure cover and the lamp base body is not desired.
  • the first and the second seal are each designed separately and at a distance from one another.
  • the second seal is preferably attached at a point that is less spaced from the lamp base body than that first seal.
  • the first seal on the other hand, can be arranged at a position that is closer to the lamp housing than the position of the second seal.
  • the first seal is arranged at least in some areas within the lamp housing.
  • the first and the second seal are preferably designed to be circumferential, that is to say closed in on themselves or without interruptions.
  • the first and the second seal can be made, for example, of silicone, rubber, EPDM (ethylene-propylene-diene-rubber) and / or NBR (acrylonitrile-butadiene-rubber).
  • the first connection and / or the second connection is a plug connection, which is preferably secured by a securing means.
  • the first connection can be created by inserting the flange into the lamp housing.
  • the second connection can then be made by inserting the pressure cover onto the lamp base body.
  • the plug connections allow the first and second connection to be established in a simple and therefore inexpensive manner.
  • a locking ring can be used, for example, which is applied to the end of the flange.
  • a fastening clip can be attached to the outside of the pressure cover and to the lamp base body, for example.
  • the basic lamp body has at least one end piece, the second connection being between the pressure cover and the end piece.
  • the end piece is therefore part of the lamp base body and can, for example, form an end of the lamp base body.
  • the pressure cover is thus also connected to the luminaire body in the area of the front end.
  • the lamp can be constructed at least essentially symmetrically and e.g. include two end pieces at the front ends of the lamp body.
  • two pressure covers can be provided which are slipped onto the two end pieces and are secured to the end pieces by means of clamps.
  • a circumferentially sealed third connection with a third seal can be provided between the end pieces and a main section of the lamp base body.
  • the end piece can also comprise a sealed opening for a mains connection cable of the lamp.
  • the lamp housing is only open on one side.
  • the illuminant housing can be coupled with two flanges in order to create a bearing of the illuminant housing on both sides and nevertheless to enable it to be rotatable about the flanges.
  • the two flanges can jointly define an axis of rotation for the lamp housing.
  • only one of the flanges can be open or continuous.
  • the end of the lamp housing can be closed, for example by sealing or closing the flange itself. Since no moisture can penetrate in the area of the closed end of the lamp housing, the first seal can be saved there. Despite the material savings for the first seal, better protection against moisture or pressurized water can be achieved through the closed end, since there are fewer seals in the luminaire overall.
  • the lamp housing of the lamp can be connected to two pressure covers by means of two flanges, although only one flange is sealed by means of a first seal.
  • an electrical power supply is only passed through a pressure cover.
  • the electrical power supply is in particular passed through that pressure cover which is connected to the lamp housing by means of the first seal.
  • the electrical connections or electrical cables for the lighting means can then be passed through the open flange. This is possible in particular when using LEDs as lighting means, since a one-sided electrical connection of the lighting means is possible without problems.
  • electrical connectors are arranged in the pressure cover and in the lamp base body, which automatically establish an electrical connection when the second connection is made between the pressure cover and the lamp base body.
  • Matched (i.e. complementary) plug connectors can therefore be provided in the pressure cover and the lamp base body.
  • the connector of the lamp base body is arranged in its end piece.
  • the plug connectors can be installed in the pressure cover and the lamp base body at fixed, predetermined positions and in particular immovably. The positions are preferably chosen so that the plug connectors automatically connect to one another when the pressure cover is inserted into the main body of the lamp.
  • an opening in the pressure cover points in a direction which is perpendicular to the direction of extent of the lamp housing.
  • the vertical alignment of the opening ensures that the pressure cover can be easily inserted into the end piece.
  • a direction that is defined by the opening of the second seal can also run perpendicular to the direction of extent of the lamp housing.
  • a direction that is defined by the opening of the first seal can run parallel to the direction of extent of the lamp housing.
  • a specific embodiment of the luminaire can be characterized, for example, in that the luminaire base body comprises two end pieces which form opposite front ends of the lamp base body, each end piece being connected to a pressure cover, the pressure cover each comprising a flange, the lamp housing on both flanges is pivotably mounted and extends between the pressure covers, the lamp housing is designed to be sealed in the area of a first pressure cover and no first seal is present in the region of the first pressure cover, the lamp housing having an opening in the region of a second pressure cover through which an electrical connection of the illuminant is guided, with a first seal being present in the region of the second pressure cover and with electrical connectors angeord only in the second pressure cover and in the lamp base body (in particular in the end piece) net, which when making the second connection between the second pressure cover and the luminaire base body (or the end piece) automatically establish an electrical connection in order to supply the light source with electrical energy.
  • a connection between the lamp base body and the lamp housing can be established exclusively by means of one or two pressure covers.
  • a latching device which allows the lamp housing to pivot in discrete angular steps causes.
  • the latching device can for example be arranged on the flange.
  • fastening clips are attached to the lamp base, by means of which the lamp base can be held on a wall or a ceiling.
  • the luminaire base body can have at least one bulge on its outside, wherein the lamp can be held on the bulge by means of a fastening clip.
  • the invention also relates to a method for assembling a lamp of the type explained above.
  • the method is characterized in that the lamp base body is attached to a wall or a ceiling.
  • a first pressure cover is connected to the main body of the luminaire by plugging.
  • a second pressure cover is connected to the lamp base body by means of plugging, with an electrical connection, in particular by means of an electrical connector, being automatically established between the lamp base body and the lamp housing when the second pressure cover is inserted.
  • the luminaire according to the invention can therefore be easily installed at its destination in just a few work steps.
  • Fig. 1 shows a light 10 in the form of a linear light for damp rooms.
  • the lamp 10 comprises a lamp base body 12 which is formed from a non-translucent material.
  • the luminaire 10 comprises a lamp housing 14 which is formed from a light-permeable material.
  • the illuminant housing 14 several LEDs are arranged as illuminants (not shown) on an elongated circuit board. The LEDs are distributed essentially over the entire length of the lamp housing 14.
  • Fig. 2 shows a front end of the lamp from Fig. 1 in a more detailed view. It can be seen that the lamp housing 14 comprises an attachment 16 at its front end. The attachment 16 of the lamp housing 14 is in Connection to a pressure cover 18. The pressure cover 18 in turn is connected to an end piece 20, which is part of the lamp base body 12.
  • a circumferentially sealed first connection I is present between the attachment 16 and the pressure cover 18.
  • a circumferentially sealed second connection II is present between the pressure cover 18 and the end piece 20. Both connections are explained in more detail below.
  • FIG. 3 the second connection II is shown separately, so that the pressure cover 18 and the end piece 20 do not touch or are not inserted into one another.
  • the Figures 4A and 4B show the pressure cover 18 in a detailed representation.
  • the pressure cover 18 comprises a flange 24, which establishes the first connection I with the attachment 16 of the lamp housing 14.
  • a first seal 26 is pushed onto the flange 24, which seal is annular.
  • a locking ring 28 can be attached to the flange 24.
  • Securing recesses 30 are provided on an outside of the pressure cover 18, into which securing clips 32 ( Fig. 2 ) can intervene to prevent inadvertent loosening of the second connection II.
  • the lamp base body 12 has to be attached to the desired position at the final assembly location.
  • the first connection I between the pressure cover 18 and the lamp housing 14 can already have been established before delivery to the final assembly location.
  • the second connection II must then be made by pushing the two pressure covers 18 onto the two end pieces 20.
  • An electrical connection can be established automatically by means of plug connectors (not shown in the figures). The final assembly of the lamp 10 can thus be done with little effort.
