Definitions

  • the invention relates to a mercury vapor low-pressure discharge lamp with a base on one side, consisting of one or more discharge vessels, at the ends of which current leads are led out, and a base body which at least surrounds the ends of the discharge vessel and is non-detachably connected thereto, the base body comprising an upper part and a ballast and ignition device holding base part, which is attached to a mounting plate.
  • Lamps of this type are known as compact fluorescent lamps from the patent literature in various embodiments.
  • the power supply lines of the respective ends of the discharge vessel must be electrically conductively connected to those of the ballast and ignition device. This is usually done by a solder or crimp connection. This complicates the assembly from a mechanical point of view, so that these compact lamps usually have to be assembled manually. However, such a labor-intensive production makes the end product more expensive.
  • the object of the invention is to simplify the construction of the compact lamps in such a way that mechanical assembly is made possible, the power supply lines of the discharge vessel being a safe electrical one Connection to the ballast and ignition device should result.
  • the upper part of the base body holds the discharge vessel and contact elements are provided with which each individual power supply of the discharge vessel in the upper part of the base body with the ballast and ignition device in
  • the lower part of the base body is electrically conductively connected, means being provided on the upper part and on the mounting plate arranged in the lower part, by means of which the electrically conductive and mechanically non-detachable connection and mounting of the contact elements with the current leads of the discharge vessel on the one hand and the mounting plate and thus on this attached ballast and ignition device on the other hand.
  • the contact elements are designed as pins.
  • the means on the upper part for contacting the power supply lines and the pins are molded onto the upper part in the form of receptacles.
  • Each receptacle has a blind hole receiving the contact pin, which is tangent to a slot and in which the associated power supply is inserted and fixed in an electrically conductive manner by the contact pin.
  • the blind hole and the slot of each receptacle is expediently provided with an insertion funnel or with an insertion slope, in order to facilitate the insertion of the current leads into the corresponding slots and the contact pins into the corresponding blind holes.
  • the means for mounting and contacting on the The mounting plate arranged in the lower part consists of corresponding contact contacts which are permanently connected to the mounting plate.
  • the contact pins can be pressed into the mounting plate and soldered to the conductor track.
  • the mating contacts are designed as resilient contact tabs which are inseparably connected to the mounting plate, for example by soldering or by interlocking fastening tabs, and which contact the contact pins in a non-positive and electrically conductive manner.
  • the contact elements are designed in particular as plug-in contacts, in which two resilient contact tabs surround a contact pin on both sides and hold it like a barb.
  • This construction results in advantages for production that do not occur in the previously known embodiments of single-ended compact lamps.
  • the separation of the base body into an upper part holding the discharge vessel and a lower part holding the ballast and ignition device enables prefabrication on two different and thus simplified assembly machines.
  • the discharge vessel is connected to the upper part in a non-detachable manner by means of a snap connection already proposed or a conventional cement connection.
  • the power leads are then inserted into the slots in the receptacles.
  • the ballast and ignition device arranged on the mounting plate has already been introduced into the lower part parallel to these operations, the contact pins on the mounting plate being unsolvable by pressing them into the mounting plate and then soldering them to the conductor tracks were attached.
  • the assembly units thus prefabricated are finally connected by simply plugging the upper part onto the lower part, locking elements in their common connection zone guaranteeing an inseparable connection and, at the same time, the contact pins, in cooperation with the current leads located in the slots, the electrical connection between the discharge vessel and the ballast. and manufacture the ignition device.
  • Conventional or electronic ballasts are equally suitable for this type of connection between the upper part and lower part of the base body.
  • a power supply and a contact pin are pressed into a common socket molded onto the upper part.
  • the ballast and ignition device arranged on the mounting plate was already inserted into the lower part, the contact elements on the conductor tracks of the mounting plate being permanently attached by soldering or by interlocking fastening tabs.
  • the assembly of the prefabricated assembly units is then continued in the manner described in the previous example.
  • the base body 1 of FIG. 1 is made of plastic and is composed of an upper part 2 and a lower part 3, which are mechanically non-detachably connected to one another by means of a snap connection 4.
  • the curved discharge vessel 5, which is coated with phosphor, is fastened to the upper part 2 with the aid of a temperature-hardenable cement 6.
  • the discharge vessel 5 has an approximately U-shaped shape.
  • two discharge vessels 5 of this type can also be connected, so that twice the discharge length results. In this case, the four straight legs are parallel to each other and arranged in a square.
  • several two-leg discharge vessels 5 can also be fastened in the base body 1.
  • a mounting plate 7 is attached, on which a ballast and ignition device 8 is mounted.
  • An inductive ballast with starter or an electronic ballast is equally suitable for this.
  • the mounting plate 7 is a printed circuit board on which the components of a high-frequency ballast are arranged. This offers the advantages of a higher luminous efficiency of the lamp as well as that compared to a conventional ballast reduced weight.
  • a base sleeve 9 is fastened, as is usually used for incandescent lamps. The base sleeve 9 enables the compact lamp to be directly connected to the socket of a lamp intended for incandescent lamps.
  • a first power supply 11 is soldered to the ground contact 10 of the base sleeve 9 and leads through the cavity in the lower region of the base body 1 to the mounting plate 7.
  • a second power supply line 12 also leads from the mounting plate 7 through the cavity in the lower region of the lower part 3, is then further bent outwards at its lower edge and lies there in contact with the base sleeve 9.
  • the lower part 3 is provided with an end groove 13 in which the power supply 12 is arranged and, after the base sleeve 9 has been fastened, it is absolutely secured by punching and fixed by clamping. This creates a secure electrical connection between the second power supply 12 and the base sleeve 9.
  • the electrical connection between the upper part 2 holding the discharge vessel 5 and the lower part 3 receiving the ballast and ignition device 8 takes place via the contact pins 14. These are pressed into the mounting plate 7 and are in electrical contact with the conductor tracks of the mounting plate 7 Ballast and ignition device 8.
  • Receptacles in the form of sockets 15 are molded onto the upper part 2 and are provided with an insertion funnel 16 at the opening. It facilitates the mechanical insertion of the contact pins 14 into the blind hole arranged concentrically with the socket 15.
  • the bushing 15 has a slot 17 tangent to this blind hole, which is provided with an insertion bevel 18 on the side facing the lower part 3. It facilitates the mechanical insertion of the power supply lines 19 into the slot 17.
  • FIG. 4 shows a slight deviation from FIG. 1. Similar parts are provided with the same number here.
  • resilient contact tabs 20 are fastened on the mounting plate 7. They are soldered into the mounting plate 7 and are in electrical contact with the ballast and ignition device 8 via the conductor tracks of the mounting plate 7.
  • the power supply lines 19 of the discharge vessel 5 are pressed together with the contact pins 14 into the sockets 15.
  • the contact pins 14 engage in the contact tabs 20 fastened on the mounting plate 7 and are held by these in a barb-like manner.
  • the assembly process carried out here applies in the same way to all four existing power supply lines 19, contact pins 14 and contact tabs 20.
