Definitions
- the invention relates to a gas discharge lamp base with an ignition device of the type known from WO 00/59269 (Dl).
- the invention has for its object to provide a gas discharge lamp base, which is of simple construction and enables automatic assembly.
- the toroidal transformer 23 of the DI is replaced by a rod core transformer.
- a ferrite plate (mushroom core or H core transformer) is preferably attached to one or both ends of the rod core transformer. In this way, a lower secondary resistance can be achieved with the same ignition voltage.
- the rod core transformer is preferably designed so that the chokes 24 and 25 of Dl can be omitted.
- the capacitor 26 of D1 connected in parallel with the lamp can also be omitted if the base is enclosed by a metal housing according to FIG. 16 of D1.
- the base according to the invention there is only one element carrying high voltage, namely the rod core transformer.
- the lamp base according to the invention there is no support 16 from Dl. Its insulating function is taken over by a modified structure of the base part 10 and the cover 40. The labyrinth on the cover and on the outer part of the base takes on the insulation function of the carrier 16 from Dl.
- the metal feed-through tubes 71 (FIG. 15 from Dl) for the connecting wires 72, which act as sealing elements and Aids can be omitted without replacement.
- the function of the return conductor connection 63 (FIG. 12 of DI) is integrated in the lead frame 60 (FIG. 12 of DI), which results in a further reduction in the number of individual parts and an easier assembly.
- the capacitor 28 is designed as an automatically populated film capacitor. With component 27 (FIG. 12 of 'DL) there is no special bending of the connecting wires, with the new geometry of the carrier 16 making more space available so that standard machines can also be fitted here.
- the collar 39 for the connector (FIG. 13 from DI) is integrated according to the invention into the outer base part 10 or the lead frame 60, whereby a full-surface connection between the cover 40 and the outer base part 10 of DI is achieved.
- Splash water protection up to IP67 (DIN 40050 "touch and water protection") is possible.
- the function of the capacitor 29 can be shifted from the igniter into the electrical ballast.
- the arrangement of the components, including the rod core transformer, on the carrier 60 from DI allows automatic assembly.
- the lead frame is angled (L or U-shaped).
- MID Molded J_nterconnect Devices
- 3D integrated conductor structure

- FIGS. 7 and 8 are exploded perspective views of the essential components of an embodiment of the gas discharge lamp base according to the invention with the rod core transformer of FIGS. 7 and 8, and
- FIG. 11 shows an angular lead frame equipped with the components.
- the upper housing parts 10 have a central pin 80 and a thinner lateral pin 81 through which the leads are led to the lamp, not shown here, to be closed from below.
- the conductor is placed in the center pin 80 on the outside of its surface and then cast.
- a partition wall 82 in the upper housing part 10 forms a chamber 84 having a step or bulge 83.
- the collar 39 is molded onto the housing of the upper part 10 'to accommodate the plug.
- the supply lines can be recognized as upright red lines, as can the foot contact on the pin 80.
- the plug 39 is molded onto the lead frame 60.
- the lead frame 60 carries the rod core transformer 23, the spark gap 27, a film capacitor 28 (FIG. 4) and a return conductor 85.
- a lower housing part 40 consists essentially of a cover plate 86 and a cylindrical, hollow, downwardly open hollow cylinder or pin 87, which is molded onto the plate 86.
- the lead frame 60 is inserted together with its assembly into the upper housing part 10, the rod core transformer 23 being received in the chamber 84.
- the bulge 83 serves to receive the connections of the rod core transformer 23.
- the rod core transformer 23 is then potted, whereby only a little potting compound is required through the partition 82, much less than in the known lamp base according to Dl.
- the conductor ends brought in by the pins 80, 81 the lamp is welded or soldered to the circuit board.
- the pin 80 Hv contact of the lamp
- the pin 81 (Lv contact of the lamp) is connected to the circuit board or the lead frame 60.
- the lower housing part 40 is inserted into the upper housing part 10 with its peg 87, the peg 87 enclosing the peg 80 and thus forming the labyrinth necessary to avoid rollovers.
- the bottom surface the cover plate 86 lies on the upper surface of the lead frame 60.
- Fig. 4 shows the exploded perspective view of a third embodiment of the lamp base.
- the lead frame 60 is provided on its upper side with a plurality of all-round webs 90, a bore for the passage of the "hot conductor" of the lamp being located in the inner oval.
- the upper housing part 40 carries corresponding webs, which cannot be seen in the illustration in FIG. 4, which engage in the grooves formed between the webs 90 on the lead frame.
- a web 92 which follows the outer contour of the lead frame 60, surrounds the rod core transformer 23 and is guided to a central circular-cylindrical eye 94, surrounds the rod core transformer 23 and thus forms a chamber 84 which is filled with potting compound. Only a little potting compound is required in this embodiment.
- the upper housing part 10 is provided on its lower surface in FIG. 4 with a circular opening 96.
- the lead frame 60 is inserted into the upper housing part 10.
- the lamp (not shown) is then inserted through the opening 96 and the circular-cylindrical web 94 in such a way that the “hot conductor” projects through the hole provided in the printed circuit board 60 into the central oval between the webs 90. It is welded to a connection located there.
- the lower housing part 40 is placed on the lead frame 60, so that the webs 90 of the lead frame 60 and those of the lower housing part 40 interlock and form the labyrinth.
- FIGS. 4, 5 has the advantage that those of FIGS. 1, 2, 3 are largely the same, that is Existing tools can be used like those of the Dl. At the same time, no adjustments to the production line are required by the customer, i.e. where the base and lamp are assembled.
- FIG. 6 shows the circuit diagram of the ignition device and the voltage supply of the ballast.
- the circuit is, as a comparison with FIGS. 11 and 17 of DI shows, substantially "slimmed down".
- the ignition device is a so-called asymmetrical pulse ignition device. Of three direct voltage connections 47, 48, 49, two are optionally used.
- the DC voltage connection 49 is grounded and is looped through to the loop connection 51. Between the connections 47 and 49 there is one or two so-called TRANSIL® diodes 52, which serve as a threshold switch.
- the connection 47 is connected to one terminal each of the primary winding 30 and the secondary winding 110 of the rod core transformer 23.
- a foil capacitor 28 and a discharge resistor 26 lie between these terminals and the connection 48.
- the second connection of the primary winding N1 is connected to the connection 48 via a spark gap 27.
- the second terminal of the secondary winding 110 of the rod core transformer 23 is led to the lamp connection 50.
- the discharge resistor 26 can be welded before assembly either on the capacitor 28 or on the spark gap 27 in automatic production, so that the assembly and
- FIG. 7 shows a perspective illustration of a rod core transformer 23, on the coil body of which a primary winding 30 is wound, in each case in sections between webs 111 formed on the coil body.
- the webs 111 are provided on the top (and correspondingly on the underside) with slots 114, in which the primary winding 30 is inserted.
- the primary winding 30 is designed to achieve a high dielectric strength in a multi-bandaged structure or with a multi-extruded structure.
- a receptacle 115 for the "hot conductor" of the lamp is connected to the coil former.
- the molded part forming the receptacle 115 is provided with a wall 117, on the outer edges of which grooves are provided. With the help of these grooves 118, the receptacle 115 is inserted into a corresponding recess in the partition wall 82 (FIG. 8). In this way, a labyrinth is formed to extend the creepage distance.
- a thickening can be seen at the end of the rod core transformer.
- the ferrite plate allows a lower secondary resistance to be achieved with the same ignition voltage.
- FIG. 8 shows the upper housing part 10 with the inserted rod core transformer 23, the base 119 of the lamp 1. Above the base 119, the “hot conductor” 120 of the lamp 1, to the right of it the return conductor 121 of the return 2 of the lamp 1 can be seen.
