Definitions
- the invention relates to a method for producing an electrically insulating potting in at least one Vergussraum, in particular in a receiving space for electrical components of a discharge lamp and a base for a lamp, in particular for a high-pressure ⁇ discharge lamp, with at least one receiving space for e- lectric Components of the lamp, the ⁇ at least partially ⁇ embedded in an electrically insulating potting ⁇ are.
- the method according to the invention can in principle be used for the production of electrically insulating potting bodies for different applications.
- the main field of application of the method is likely to be in the potting of receiving spaces for electrical components in the base of a high-pressure discharge lamp.
- Such a high-pressure discharge lamp is at ⁇ play, from EP 1511130 Al of the Applicant ⁇ be known.
- a base with an ignition transformer arranged therein for generating the ignition voltage for the discharge lamp is used, in which an electrical contact element is arranged, which connects a voltage output of the ignition transformer with ei ⁇ ner socket side from the discharge vessel of the lamp ago ⁇ executed power supply.
- the contact element for better electrical insulation tion ⁇ embeds in sections in the base of plastic inserted.
- the base has two chambers, wherein a first end of the electrical contact element extends into the first chamber and the second end of the contact element is accessible from the second chamber.
- the ignition transformer is arranged in the first chamber and its ignition voltage output connected to the first end of the contact element, while in the second chamber further electronic components of the ignition device of the discharge lamp are housed, the lower Anforderun ⁇ conditions to the voltage isolation as the ignition transformer.
- the second end of the contact element is accessible from the second chamber in order to be connected to the power supply leading out of the discharge vessel near the base.
- the power supply of the lamp burner is inserted into a bore of the second end of the con ⁇ tact element and welded thereto. As ⁇ by a separate spatial arrangement of the high voltage ⁇ tion leading ignition transformer is possible.
- the joint located in a receiving space between the second end of the contact element and the En ⁇ de the socket near power supply and the ignition transformer is embedded in an electrically insulating potting compound, which is introduced into the chambers and e - Lectric insulation between the electrical components, in particular between the contact element and the primary winding of the ignition transformer is formed.
- the invention has for its object, a Ver ⁇ drive for producing an electrically insulating cast as well as a socket for a lamp, and in particular to provide for a discharge lamp in which ge ⁇ genüber conventional solutions improved electrical isolation with minimal device technology Effort is possible.
- the potting compound can expand at any temperature change and contract without causing stress within the potting compound. Cohesive failures, ie the off ⁇ formation of stress-induced cracks in the sealing compound can be safely avoided. Wall detachment in the high-voltage critical area is also avoided since the mechanical stresses in the critical area no longer exist in the uncritical region after detachments have occurred.
- a fabric system base plastic / potting compound is used, which has a rather poor adhesion of Verguss ⁇ mass on the base plastic with untreated So ⁇ ckelguesstoff.
- a fuel system base ⁇ plastic / sealing compound is preferably further used having a very good adhesion of the potting compound on the base plastic at the base treated resin.
- any suitable method such as primers or Plasmabe ⁇ treatments can be used.
- the actual Vergusspro- process takes place preferably in a vacuum.
- FIG. 1 bottom plan view of a erfindungsge ⁇ MAESSEN lamp base with a casting space 214 and a partial cavity 221 treated by the method according to the invention.
- FIG. 2 perspective view of a erfindungsge ⁇ MAESSEN lamp cap with a casting space 214 and an inventive after
- the preferred method for producing an electrically insulating potting body is carried out in a vacuum potting process known per se.
- a kit is a fabric system that has a low adhesion of the potting compound on these in untreated surfaces of the base resin.
- the partial cavity 221 in the base part 21 is pre-treated by a plasma treatment process to ensure a good ⁇ Haf tung the casting compound in the pretreated area.
- the remaining wall surfaces of the cavity 214 that is, the partial cavity 222, which is not critical with respect to the high-voltage strength, is not treated.
- the ignition transformer is inserted into the cavity and contacted.
- the ignition transformer can also be treated on its surface which correlates to the partial cavity 221 prior to introduction into the cavity.
- the casting compound used is preferably a two-component silicone casting compound.
- any other suitable potting compound for example a potting compound based on polyurethane or epoxy resin. This can be embodied as a one-component as well as a two-component casting compound.
- the parts are finished in principle, but for quality assurance, they can still be subjected to a combined thermal cycling and ignition test to ensure that the potting compound at the predetermined locations, ie the Generalkavtician 222 ⁇ dissolves from the wall of the cavity, while the Wall adhesion in Kav. 214 is fully preserved. Depending on the potting compound, however, this already happens during the cooling phase after curing, since the potting compound then contracts.
- plastic material for the base all suitable plastics can be used, preferably plastics based on PEI (polyetherimide), PPS (polyphenylene sulfide) or LCP (Liquid Crystalline Polymers) are used. These plastics have a high temperature turfesttechnik and a high electrical breakdown strength ⁇ and thus come as a pedestal plastics in Fra ⁇ ge.
- PEI polyetherimide
- PPS polyphenylene sulfide
- LCP Liquid Crystalline Polymers
