Definitions
- the invention relates to a low-pressure discharge lamp according to the preamble of patent claim 1.
- Such low-pressure discharge lamps designed as compact fluorescent lamps are described, for example, on the Internet domain www.osram.de under the product designations "DULUX® L, DULUX® D or DULUX® T".
- the discharge vessel consists of one or more U-shaped bent discharge vessels, which are inserted into a base and glued to it.
- this is made in two parts, consisting of a base top and a base base.
- a disadvantage of the above-described solution is, on the one hand, that such lamps have a high weight, since the base parts overlap in the connection region and, on the other hand, are very expensive due to the required dimensional accuracy of the base parts in the production. Furthermore, there may be a breakage of the base due to insufficient connection forces between the base parts.
- a low-pressure discharge lamp with a one-piece socket known.
- an annular adhesive layer on the inside of the base skirt surface is applied before insertion of the discharge vessel in the base, which is fixed at room temperature and is activated after insertion of the discharge vessel by heat input and causes a firm connection between the base and the discharge vessel.
- the invention has for its object to provide a low-pressure discharge lamp, in particular a compact fluorescent lamp, which has a low weight in a simplified manufacturing process.
- the low-pressure discharge lamp according to the invention has at least one discharge vessel, which is inserted into a base and connected to it via a connecting mass.
- the base has at least one recess, via which the connection compound can be introduced when the discharge vessel is inserted.
- the manufacture of the lamp considerably simplifies, since the bonding compound in comparison to the prior art does not have to be solid at room temperature and all suitable bonding compounds and manufacturing processes can be used. Due to the recesses in the base can continue the use of material and thus the weight of the base considerably be reduced.
- the compound compound can be introduced after the onset of the discharge vessel targeted to the desired connection points. This improves the strength of the socket / discharge vessel connection with minimal consumption of bonding compound.
- the base is preferably made in one piece, with the strength of the base further improved with reduced weight.
- the recess is arranged in a bottom wall of the base.
- the recess is arranged centrally in the bottom wall and adapted with a constriction to the outer contour of the discharge vessel.
- the recesses between a base box holding connecting webs are arranged.
- a bonding compound is preferably an adhesive or putty use.
- the bonding compound is preferably introduced into a space bounded at least in sections by the discharge vessel and the base.
- At least two contact pins which serve for electrically contacting the low-pressure discharge lamp in the lamp socket and / or at least two connecting sleeves, in particular crimp sleeves for connecting a capacitor wire with a glow starter wire and an electrode wire are fixed to the connecting webs. Since the crimp sleeves are inserted into the base, the manufacture of the lamp is simplified considerably due to the defined positioning of the wires.
- four contact pins are fixed in the connecting webs.
- the base box accommodates electrical components of the lamp, in particular an interference suppression capacitor and a glow starter.
- the base is circumferentially substantially adapted to the contour of the discharge vessel. This further reduces material usage, reduces lamp weight and improves the design of the lamp.
- the lamp has a lid for covering the recesses.
