Definitions

  • the present invention relates to a luminaire with a luminaire rear wall for mounting on a wall or ceiling, a printed circuit board which is equipped with several light emitting diodes and which has a connection cable as a light source, and a connection terminal which is connected to the connection cable and to which a supply cable can be clamped.
  • Luminaires are expected to provide uniform illumination. This is not only desirable for the illumination of the respective surfaces, but also desirable for the overall appearance of the lamp.
  • connection wiring which is often routed via the LEDs in the light path, is problematic with regard to any shading. This creates unwanted shadows and artifacts, for example on the lamp cover.
  • connection cables that come from the wall and the cables that come from the light source are placed next to the light source in order to produce as little shadowing as possible.
  • this has a negative impact on the size of the light source and the shape of the lamp.
  • connection lines are shown on the luminaire covers.
  • ballast In practice, a solution is also widespread in which a separate ballast is placed between the wall connection line and the light source. This ballast requires space and either leads to shading on the Luminaire cover or dark spots due to lack of illumination, as the LEDs have to be placed around the ballast. Consequently, there is then a lower luminance in the area of the ballast, which is noticeable, for example, as a dark zone on the luminaire cover.
  • the document WO 2014/079138 A1 discloses an LED ceiling light.
  • the ceiling light includes a housing, a power supply, an LED light source plate, and a lamp cover connected to the housing.
  • the LED ceiling light further comprises a support part, the support part is located between the housing and the LED light source plate, so that a certain distance is formed between the LED light source plate and the housing.
  • the power supply is located between the housing and the LED light source plate.
  • the document CN 201836778 U discloses an LED ceiling light.
  • the back wall of the luminaire and the LED circuit board are spaced apart.
  • a power supply unit and a ventilation fan are arranged between the back wall of the luminaire and the LED circuit board.
  • the document CN 201251064 Y discloses an LED ceiling light.
  • the back wall of the luminaire and the LED circuit board are spaced apart.
  • a power supply unit is arranged between the back of the luminaire and the LED circuit board.
  • the object of the present invention is therefore to provide a lamp whose lighting means has a plurality of LEDs or light-emitting diodes and whose illumination is as homogeneous as possible.
  • a luminaire with a luminaire rear wall for mounting on a wall or ceiling is provided.
  • This back wall of the luminaire is therefore prepared for mechanical fastening to a wall, a ceiling or another carrier and has, for example, corresponding bores.
  • the back wall of the luminaire can have a recess through which supply lines, for example from a 230 V supply network, can be passed.
  • the lamp has a printed circuit board that is equipped with several light-emitting diodes and that has a connection cable. The light-emitting diodes are typically evenly distributed on such a circuit board in order to achieve homogeneous illumination.
  • connection cable which is connected to the supply cable during assembly.
  • connection cable is typically two- or three-core.
  • connection cable can also be connected to the connection cable.
  • the connection of the connection cable to the supply cable or the supply cables can be realized with a connecting terminal of the lamp.
  • a connection terminal from WAGO can be used, for example.
  • the LED luminaire is equipped with a spacer that is permanently mounted on the back wall of the luminaire and on which the circuit board is releasably attached, creating a free space between the circuit board and the back wall of the luminaire.
  • the printed circuit board is therefore not attached directly to the back wall of the luminaire, but one or more spacers ensure that a predetermined distance is created between the printed circuit board and the back wall of the luminaire, by means of which the said free space is defined.
  • This free space can optionally also have the advantage that air can circulate behind the circuit board and cool it accordingly.
  • the connection cable is also arranged entirely or largely and the connecting terminal in the free space.
  • connection cable at most with its connection area or an insignificant part of its total length runs on that side of the circuit board on which the light-emitting diodes are arranged.
  • the main part or the entire free part of the connection cable runs on the rear side of the circuit board facing away from the light-emitting diodes, that is to say in the free space between the circuit board and the back wall of the light.
  • the connecting cable and the connecting terminal cannot shade the light-emitting diodes.
  • the result is a more homogeneous illumination of the optionally provided lamp cover or the illuminated surface.
  • ballast is integrated in the circuit board.
  • the ballast can form a self-contained unit or individual components of the ballast are distributed over the circuit board, as are the light-emitting diodes themselves. In the latter case, light-emitting diodes can be placed between the components so that the ballast area does not necessarily have to be dark.
  • a ballast of the lighting means is arranged in a separate housing in the free space between the circuit board and the back wall of the lamp.
  • standard ballasts can be used, as a result of which, for example, the production costs of the lamp can be reduced.
  • the ballast in which the ballast is arranged in its own housing between the printed circuit board and the lamp back wall or lamp back plate, the ballast itself or its housing is designed as the spacer.
  • the ballast together with the spacer, can define a distance between the printed circuit board and the back wall of the lamp. If necessary, the ballast or the housing is even the only spacer between the back wall of the luminaire and the circuit board. In this way, the ballast receives the additional functionality of the spacer, whereby the assembly effort can be further reduced.
  • the spacer and the circuit board are attached to one another by a releasable snap connection.
  • This has the advantage that the circuit board only has to be pressed onto the spacer in order to fasten it there by means of the snap connection.
  • the snap connection can be released again without tools or with a tool.
  • the spacer has a latching hook and the circuit board has a recess, the latching hook being releasably hooked in the recess.
  • the arrangement of the connecting elements can also be provided as a mirror image.
  • the circuit board would then be equipped with a latching hook and the spacer would have a corresponding recess.
  • a snap connection can be implemented relatively more easily.
  • the spacer has a cylindrical base body which is firmly connected to the rear wall of the lamp on a first end face.
  • the base body can be glued or screwed to the rear wall of the luminaire.
  • the cylindrical base body can also only be attached to the rear wall of the lamp and hold there by means of a non-detachable snap connection.
  • the cylinder shape is understood here to mean any general cylinder and thus, in addition to the circular cylinder, for example also a prism or cuboid.
  • the latching hook has a pin-shaped first section which protrudes vertically from a second end face of the cylindrical base body opposite the first end face, and a pin-shaped second section is formed at an acute angle to one another at the distal end of the first section.
  • a third section is integrally formed at an obtuse angle on the distal end of the second section.
  • a certain spring property can also be found in the connection between the second section and the third section of the latching hook.
  • a latching hook can be produced, for example, as an injection-molded part.
  • a suitable plastic should be used that guarantees the spring properties. If necessary, the latching hook is even formed in one piece with the base body of the spacer and, in particular, is cast in one piece.
  • the circuit board is attached to the spacer by a bayonet connection element.
  • a corresponding bayonet connection represents a reliable fastening that can be carried out quickly and just as quickly released again.
  • the circuit board is fastened to the rear wall of the lamp exclusively by the spacer or several such spacers. This means that no further assembly elements than the spacers themselves or the connecting elements formed thereon are necessary in order to hold the circuit board on the rear wall of the luminaire. In particular, the edge of the circuit board is then not supported in any way, for example on the rear wall of the lamp. This lack of further fastening elements also leads to a more cost-effective production, simplified assembly and improved air circulation between the circuit board and the back wall of the light.
  • the lighting means here a circuit board with light-emitting diodes, is manufactured to match the shape of the light, in order to achieve the most homogeneous, shadow-free illumination possible.
  • cables on the wall and luminaires are deposited in such a way that neither shading nor dark zones are caused.
  • a lamp is mounted on a ceiling 1.
  • a lamp can also be mounted on a wall or other support.
  • the lamp has a lamp rear wall 2 with which it is attached to the ceiling 1 or the other carrier. This attachment can take place, for example, by means of screws and dowels.
  • the lamp rear wall 2 can be designed in the form of a plate, but also, for example, in the shape of a plate. In one embodiment, the lamp rear wall 2 is circular. But it can also be designed oval, square or some other shape.
  • the lamp rear wall 2 can have one or more holding elements, for example tabs 3, with which a lamp cover 4 can be attached to the lamp rear wall 2.
  • the lamp cover 4 can for example have a transparent ring.
  • Fig. 2 also shows that the lamp rear wall 2 has, for example, a plurality of holes 5 with which the ceiling mounting, wall mounting or the like can take place.
  • the lamp has a printed circuit board 6 with light-emitting diodes as a light source (cf. Fig. 3 ).
  • this circuit board is designed to be round. But it can also have a different geometric shape.
  • the circuit board 6 is arched in the shape of a plate in the present example. This, too, is only to be seen purely as an example.
  • the circuit board 6 can also be purely planar, for example.
  • the printed circuit board 6 can optionally also be configured in the shape of a concave mirror.
  • the light source that is the printed circuit board 6 with light-emitting diodes, is mounted at a distance from the rear wall 2 of the light. This creates a free space 7 between the luminaire rear wall 2 and the circuit board 6. In this free space, wall or ceiling-side supply lines, which together form a supply cable 8, and lamp-side connection lines, which together form a connection cable 9, as well as connection plugs or connection terminals 10 are deposited.
  • the number of connecting terminals can be one, two, three or more.
  • a connection terminal from WAGO can be used.
  • the light path extends downwards starting from the circuit board 6, and the connection cable 9 and the connecting terminal 10 are essentially above the circuit board 6. Since these connection elements are no longer in the light path, they do not create any shadows on any lamp cover or on the surfaces to be illuminated.
  • the lamp or the printed circuit board.6 with the light-emitting diodes is in the light by means of spacers 11 positioned so that the necessary distance and thus the free space 7 is created.
  • the distance should be at least 10 mm so that one or more connecting clamps 10 can be comfortably positioned in the free space 7. In a specific example, a distance of 12 mm is maintained. This is sufficient for NYM 3x1.5 mm wiring (supply cable 8), the lamp connection lines (connection cable 9) and several connection terminals 10 (e.g. WAGO 224-101).
  • the spacer or spacers 11 are fastened to the side of the lamp rear wall 2 facing the printed circuit board 6. This can be done, for example, by screws 12, as shown in FIG Fig. 2 is indicated. Alternatively, the spacers 11 can also be glued to the rear wall of the lamp or, for example, attached by a non-releasable snap connection.
  • Fig. 3 shows an embodiment of a lamp without a lamp rear wall in the front view, ie from the light side.
  • the luminaire here has a transparent, shell-shaped luminaire cover 4. Behind it, the circular circuit board 6 can be seen. Numerous light-emitting diodes 13 are arranged on the circuit board 6. As far as possible, the light-emitting diodes 13 are evenly distributed on the surface of the circuit board 6, so that a uniform luminance is achieved.
  • the connection cable 9 with two lines can be seen in the center of the circuit board.
  • a strain relief 22 protects the soldered points of the connection cable 9 from excessive tension.
  • Fig. 4 gives the back of the circuit board 6 of Fig. 3 again.
  • the connection cable 9 protrudes from the center with its two lines (for example for the conductors L and N of the wall wiring). At the end of the lines of the connection cable 9 there are insulated connection plugs or connection terminals 10.
  • the strain relief 22 on the lead-through of the circuit board 6 for the connection cable 9 can also be seen from the rear of the circuit board 6 in the present example.
  • connection cable 9 is not restricted to precisely two lines. Rather, the connection cable 9 can also have one, three or more cables. However, it is essential that the majority of the connection cable 9 is located on the rear of the circuit board 6. Only an insignificant part of the connection cable 9 is located in the present example on the front side, what Fig. 3 shows. The cable bushing of the circuit board 6 is therefore in the immediate vicinity of the connection points at which the connection cable 9 is clamped or soldered. Because the cable 9 is led through immediately after the connection points on the rear side of the printed circuit board 6, in the present example more than 90 percent of the connection cable 9 is on the rear side. The length of the connection cable 9 or of each connection line is preferably not greater than the mean distance between the light-emitting diodes in the area of the connection points of the circuit board 6.
  • the LED light usually also has a ballast.
  • This ballast is either integrated on the circuit board or housed and mounted in the free space 7 between the circuit board 6 and the back wall 2 of the lamp in a separate housing.
  • the ballast is integrated on the circuit board 6.
  • the printed circuit board 6 has corresponding components 14. These components 14 of the ballast are so small in their dimensions that they practically do not lead to shadowing. They also do not protrude beyond the light-emitting diodes 13 of the circuit board 6.
  • this housing can also be used as the spacer for the printed circuit board 6 opposite the Lamp back wall 2 can be used. If necessary, additional spacers 11 are used.
  • spacers 11 are used. This is sufficient without overdetermination.
  • the number of spacers 11 can, however, also be less or more than three.
  • the spacers should be designed in such a way that the light source, namely the circuit board 6, can be pulled out of the luminaire before assembly and can be plugged back onto the luminaire rear wall 2 after the rear wall 2 and the connecting lines 9 have been assembled.
  • the spacers should therefore create an easily detachable connection between the rear wall of the lamp 2 and the circuit board 6 for the user. In this way, the illuminant can be completely free of shape and optimal illumination can be guaranteed.
  • circuit board 6 is held by a hinge on the lamp rear wall 2 and the circuit board 6 is locked, for example, on a spacer.
  • the hinge or hinges preferably have the same or a similar distance that the spacers cause between the circuit board and the back wall of the lamp.
  • Fig. 5 shows a specific embodiment of a spacer 11.
  • This spacer 11 has a cuboid or cylindrical base body 15. In the present example, it is a cuboid or a square cylinder with rounded edges, a first end face 16 and a second, opposite end face 17.
  • a first pin-shaped section 18 protrudes from the second end face 17. This can, for example, have a length in the order of magnitude of the height of the base body 15.
  • this first section 18 is aligned perpendicular to the lamp rear wall 2.
  • At the distal end of the first section 18 there is a second section 19 at an acute angle molded.
  • a third section 20 is formed at an obtuse angle.
  • the three sections 18, 19 and 20 form a locking hook.
  • the first section 18 and the second section 19 are elastically connected to one another, so that the acute angle between them can be reduced by pressure on the second section 19.
  • a snap connection can be implemented, for example by inserting the latching hook into a recess 21 (cf. Fig. 2 and 4th ) is pressed.
  • the third section 20 of the latching hook ensures that the snap connection can be released again without being destroyed.
  • the latching hook 11 can for example be cast from a plastic. It is particularly advantageous if it is cast in one piece. With regard to the choice of material, attention should be paid to the flexibility between the first section 18 and the second section 19 of the latching hook.
  • a spacer is advantageously provided, with the aid of which a cavity is created between the luminaire rear wall 2 and the lighting means or circuit board.
  • This allows the connection lines to be laid in such a way that no shadow is visible on any luminaire cover.
  • the lamp can be separated from the rear wall of the lamp 2 and the rear wall of the lamp 2 can be screwed to the ceiling or another carrier without hindrance. Both ends of the cable can then be simply connected.
  • the light source can be easily removed from the ceiling-mounted luminaire without restricting the light image.
