Definitions

  • a socket receiving a light bulb is arranged in a housing.
  • the housing is attached to a load-bearing component using a bracket or other fastening device (spot light).
  • spot light In other cases, the housing is held by an arm.
  • the arm can in turn be attached to a table or to the wall.
  • Other lights are supported on tubular supports connected by feet (floor lamps for table or floor).
  • plug contacts so that the lamp can be plugged into a wall socket as a plug-in lamp.
  • the invention is therefore based on the object of designing a living and / or work lamp in such a way that it can be assembled from simple prefabricated units without wiring and largely without connecting elements, such as screws, rivets or the like.
  • an elongated circuit board can be inserted into the housing and held in such a way that one end connects to the contacts of the socket, while the other end can be connected to an electrical supply line.
  • the current conductors are provided in a printed circuit board, as is the case in many other fields is used on a large scale.
  • the circuit board like the other lighting parts, can be easily installed in the housing and at the same time establishes the electrical connection to the contacts of the socket. It is particularly advantageous if the contact elements of the socket are part of the circuit board.
  • the circuit board is fixed in its position with respect to the socket in the housing, so that the contact elements have the correct position relative to the socket. An assembly of the contact elements on the socket and a screwing of conductors with terminals in the socket for establishing a power connection can therefore be omitted.
  • a switch is attached to the lamp housing.
  • a switch is integrated with the printed circuit board, the switch or the switch contact of the printed circuit board being able to be actuated with the aid of a switch actuation mounted in the housing, for example with the aid of a rocker switch.
  • the socket is usually made as a ceramic part. Special precautions are therefore necessary to fix such a socket in the housing and to establish the electrical connection. Ceramic frames are also relatively large because of a minimum wall thickness. They also have considerable weight.
  • the housing and socket are made of heat-resistant plastic and are connected to one another via a snap-in connection.
  • the socket can have a collar which interacts with the inner edge of an opening in a reflector, while the housing bears against the outside of the reflector.
  • the socket preferably has a guide which interacts with a guide of the housing.
  • the housing when molded from plastic, is usually designed as a closed hollow body, for example in the form of a tube.
  • the frame can be divided lengthways. This makes it easier to manufacture. This also makes it easier to assemble the socket and printed circuit board.
  • the socket can have stop surfaces which interact with stop surfaces of the printed circuit board and which fix the socket both in the longitudinal and in the transverse direction and in the circumferential direction.
  • the socket can be connected to the printed circuit board or molded in one piece with it.
  • a power supply unit for a low-voltage lamp can be integrated in the circuit board.
  • the other end of the circuit board is preferably designed as a plug or as a socket for an electrical plug connection.
  • connector pins can be connected to the circuit board protrude from the end of the case.
  • the plug pins can be inserted into a socket, the plug pins both establishing the electrical connection and serving as a carrier.
  • a ring-like part can also be snapped onto the end of the housing, which matches the outer contour of a protective contact plug. In this case, the ring-like part takes over the force.
  • a plug-in connection can also be advantageous.
  • the supply cable is provided with a plug or a socket and merged with a socket or a plug of the printed circuit board in the housing. If it is to be avoided that this plug connection is loosened again in use, appropriate mechanical means must be provided in order to prevent the cable from being pulled out or separated from the circuit board.
  • connection technology There are numerous known examples in connection technology.
  • the arrangement of printed circuit boards in lights is not limited to luminaire housings, but can also extend to supporting or supporting components, such as arms, supports or the like. It is also possible to have two conductors with arm sections at an angle to one another provide plates in each arm section and to establish a connection between the circuit boards, which can also be pivotable about the same axis as the arm sections.
  • the plug-in lamp has a reflector screen 1, a housing 2, a circuit board 3 and a socket 11.
  • the circuit board 3 carries at its front end two socket contacts 6 and 7, which are inside the socket 11 in the assembled state of the lamp. At its rear end, the circuit board 3 carries two contact pins 4 and 5, which are designed to be plugged into the socket.
  • the contact pins 4 and 5 are conductively connected to one another via conductor tracks 8 and 9.
  • the conductor track 8 is interrupted and can be bridged using the contact spring 10.
  • the conductor tracks are manufactured using conventional technology, for example photochemical reproduction.
  • a switch rocker 18 is pivotally mounted within the housing 2 and has a projection 19 which projects downward onto the contact spring 10.
  • the switch rocker 18 has recesses 26 into which molded housing-fixed pins 27 of the housing engage.
  • the socket 11 is first inserted through the opening 20 of the reflector 1. Then the printed circuit board 3 is connected to the socket 11 by firstly inserting recesses 25 in the printed circuit board 3 onto pins 24 of the socket 11. The two connected socket halves are then folded together and the pins 24 passing through the recesses 25 engage in the pin holes 27.
  • the unit thus assembled from socket 11, printed circuit board 3 and reflector 1 is inserted into the longitudinal guide grooves 12 and 13 from the end face 21. The insertion is carried out until the latches 14 and 15 of the socket are resiliently latched into the corresponding recesses 16 and 17 of the housing 2.
  • the reflector screen is immovable in the axial direction, but rotatably mounted about the longitudinal axis 21 of the socket 11.
  • the reflector screen 1 is held between the end edge 22 of the housing 2 and the collar 23.
  • Socket 11 and tubular housing 2 are molded from heat-resistant plastic.
  • the printed circuit board 30 which has a plate-shaped carrier 31 made of suitable insulating material, which is printed with electrical conductor tracks.
  • the plate is slightly reduced in width at 32 at the rear end.
  • a bridge 33 made of suitable plastic carries the contact pins 4, 5.
  • the bridge 33 which is prefabricated with the contact pins 4, 5, is welded or glued to the plate 31.
  • Contact wires 34 pointing towards the plate are guided through bores in the plate 31 to the other side and are connected to conductor track sections via solder connections.
  • contact spring strips 35, 36 are arranged, which have an attachment that cannot be seen, which is also guided through a hole in the plate 31 and is connected to the associated conductor track via a solder connection.
  • two contact elements 37 are arranged, the other through pins through holes in the plate 31
  • a movable switch contact (not shown) can either connect the contacts 37 to one another or separate them from one another.
  • the movable switch contact can be seen at 38 in FIG. 6. 6 consists of approximately the same symmetrical longitudinal halves, one of which is shown at 39. It has a collar 40 which is similar to the collar 23 of the lamp according to FIG. 1.
  • the socket half 39 also has a threaded portion 41 for the screw thread of a lamp, which is indicated at 42.
  • An arm 43 pointing to the rear carries an eye 44 for receiving a bearing pin of the switch rocker 18.
  • the arm 43 has a section 45 which is angled downwards at right angles.
  • the socket half 39 also has two diametrically opposed radial lugs 46, 47 which are received by corresponding grooves or guides in the housing 2, as indicated at 47a.
  • the socket can also halves 90 0 lying offset wing-like extensions have to cooperate with further guides in the housing. 2
  • the socket halves are put together in the manner described above and connected to the reflector, with an opening 49 for the rocker switch 18 remaining free upwards.
  • we insert the circuit board 30 into the socket with the front end of the circuit board in opposite slots of the socket halves engages, one of which can be seen at 50.
  • the contacts 35, 36 extend in the correct position into the socket, so that a contact is made in the usual manner when screwing in a lamp 42.
  • the circuit board 31 is, as already described above, guided by suitable guides in the housing 2. In order to prevent a displacement in the longitudinal direction, the lugs 45 of the socket halves engage in a recess 52 in the plate 31.
  • the rear flattened section 53 of the housing 2 is somewhat reduced in width. For this reason, the plate 31 is somewhat reduced in width at 32.
  • the reduction in width serves to push on a plug ring 54, which is indicated by dashed lines in FIG. 6.
  • the ring 54 is also formed from plastic and forms a latching connection with the rear section 53.
  • projections 55 are formed on section 53 on opposite sides, which engage behind corresponding lugs in the interior of ring 54.
  • the ring 54 has the outer contour of a protective contact plug, so that the ring is used for holding purposes in the case of protective contact sockets.
  • the printed circuit board 30, socket and reflector are mounted, they are pushed into the housing 2 in the manner described above, with a single lug 56 engaging in a corresponding opening in the housing. This makes the frame and the ladder plate 30 securely fixed in the housing. Furthermore, the reflector screen 1 is attached to the housing and rotatably mounted in the manner described above. The switch rocker 18 is then inserted from above.
  • Fig. 8 shows parts of a halogen lamp operated with low voltage.
  • a circuit board 60, a reflector 61 and a mains transformer 62 are provided in detail.
  • the reflector 61 has a socket base 63 which protrudes rearward and receives a halogen lamp 64. From the base 63 there are connector pins 65 to the rear.
  • the transformer 62 has two pairs of downward tabs, one of which can be seen at 66. They interact with pairs of sockets 67, 68 on the circuit board 60.
  • the sockets 67, 68 are electrically connected to the associated conductor tracks on the circuit board 60.
  • Four tubular supports 69 serve to support the laminated core 70 of the transformer 62 and accommodate fastening screws, not shown, which are passed through the laminated core 70.
  • the block-shaped socket 71 can either be formed in one piece with the plate 60 or can be applied subsequently by gluing, screwing and the like.
  • Clamping stones 72, 73 are arranged on plate 60 on the side opposite socket 71. They can also be fastened by suitable means or can be formed in one piece with plate 60.
  • the clamps arranged therein are electrically connected to a pair of conductor tracks , 73 are used to fasten the stripped ends of insulated conductors 74, 75 which carry mains voltage.
  • a suitable plug socket can also be provided for receiving a mains plug on which the mains voltage is present.
  • the lamp housing is not shown. It goes without saying that the components shown in FIG. 8 can be accommodated and fastened in a suitable manner in the lamp housing.
