Definitions

  • the present invention relates to a lamp having a lamp envelope, in particular a glass envelope, and an adapter for connecting a lamp envelope and a base of the lamp. Moreover, the invention relates to a method for producing the lamp and the adapter.
  • the above-mentioned lamps are designed, for example, as incandescent lamps or LED retrofit lamps.
  • an electric incandescent lamp known with a cylindrical glass bulb which is formed at one end to a semicircular dome and the vessel neck is provided with a glass thread. On the glass thread a screw base sleeve is applied, which is connected at its lower end with a base stone.
  • connection between the glass bulb and the lamp base has hitherto been generally realized by lamp cement or adhesive.
  • the connection of lamp cement or adhesive and the lamp base takes place on the outer surface of the glass bulb.

  • the lampkitt also is usually visible in the plan view of the lamp.
  • an intermediate ring is used as another component, on one side of the base and on the other Side of the glass bulb is attached.
  • the connection to the glass bulb is realized by an adhesive, for example silicone, on the outer region of the glass bulb. Geometric deviations of the glass bulb displace the adhesive to different extents. This creates an unaesthetic impression of this bond. Furthermore, the radiation of the light is disturbed eg by refraction, absorption, scattering.
  • this object is achieved by a lamp having the features of the protection claim 1 and an adapter with the features of the protection claim 21.
  • a lamp comprising: a lamp envelope having a tubular recess, a socket, and an adapter for connecting the lamp envelope to the socket, the adapter having a first receiving portion received in and secured within the tubular recess.

  • the assembly of the lamp is facilitated because the adapter easier on the lamp envelope can be fixed, in contrast to the connecting ring used in the prior art. This must be kept exactly to the lamp bulb, otherwise it can easily slip on the outside and thereby lead to an unclean adhesive connection with the lamp envelope.
  • the attachment of the adapter in the tubular recess of the lamp envelope creates additional space, since no lamp cement must be provided in the socket to connect the lamp envelope or an adapter to the base. The entire base interior is thus also available for the inclusion of parts such as power supply and electronic devices, etc. available.

  • the passage is formed as a tubular opening.
  • the tubular opening may have a constant cross section or a varying cross section.
  • the varying cross-section of the tubular opening may be, for example, a cross-section tapering from the entrance to the exit of the tubular opening, which means threading of the conductor wire at the entrance and the positioning of the conductor wire at the outlet simplified.
  • the adapter has a sleeve.
  • the collar receives or covers a portion of the outside of the lamp envelope.
  • the sleeve can be made transparent, which increases the light output.

  • the adapter 3 with its sleeve 25, the first receiving portion 13 and the second receiving portion 14 may for example be made entirely of a material, e.g. Plastic, in particular transparent plastic, or a combination of materials to be produced and produced for example in plastic in single or multi-component injection molding.
  • a material e.g. Plastic, in particular transparent plastic, or a combination of materials to be produced and produced for example in plastic in single or multi-component injection molding.
  • the invention is not limited to glass, ceramic and / or plastic as a material nor to the injection molding process for plastic. Any other suitable material or material combination and manufacturing method for the adapter 3 may be used.
  • LED bulbs including the in Fig. 2, 3rd and 4 shown LED retrofit lamp 1
  • the adhesive preferably transparent adhesive, for connecting the first receiving portion 13 with the tubular recess 6 and / or the projection 8 in the tubular recess 6, for example in the form of a rod-shaped portion.
  • the adhesive may be less heat resistant with an LED lamp, including the in Fig. 2, 3rd and 4 shown LED retrofit lamp, as an incandescent lamp as a lamp. 1
  • a bottom 26 of the second receiving portion 14 may optionally be additionally provided with at least one rib, for example a circumferential rib 27 around the opening 17 for the projection 8.
  • the rib 27 on the bottom 26 of the second receiving portion 14 causes the electronic device 12, when it is received in the second receiving portion 14, does not rest on the bottom 26 on the entire surface.
  • the adapter 3 can be connected to the lamp envelope 2 according to the invention by the first receiving portion 13 is glued, for example, in the tubular recess 6.
  • the adhesive 30 for bonding the first receiving portion 13 with the inner wall 7 of the tubular recess 6 is in Fig. 5 indicated on one side.
  • the first receiving portion 13 with the projection 8, for example in the form of the rod-shaped portion are glued. This is in Fig. 5 not shown.
  • the projection 8 for example in the form of the rod-shaped portion, in the opening 17 of the first receiving portion 13 only eg loosely received.
  • a recess may be provided for receiving the projection 8.
  • the adapter 3 can additionally or alternatively be fastened with its first receiving portion 13 in a non-positive and / or form-fitting manner in the tubular recess 6.
  • the outer ring of the adapter 3, so the sleeve 25, also be reduced. In extreme cases, can be completely dispensed with this outer ring or the sleeve 25, since it has no holding function. In this case, then the base 4 should preferably extend to the glass of the lamp bulb 2.
  • the effective thermal effective contact area between the adapter 3 and lamp bulb 2 is significantly increased, so more heat can be transferred or be discharged. This additionally contributes to the cooling of the glass body of the lamp bulb 2.
  • the sleeve 25 could not be connected cleanly to the outside of the lamp bulb 2. This is because the sleeve 25 without the first receiving portion 13 can not be centered on the lamp bulb 2 outside, but slips off. However, this leads to an unclean adhesive edge, which is visible to a viewer of the lamp.
  • the sleeve optionally additionally forms a support 28 for positioning the adapter 3 on the base 4.
  • the support 28 prevents the adapter with its second receiving portion 14 can be screwed too far in the base 4.
  • the adapter 3 for example made of plastic
  • the adapter 3 with the previously based on the Fig. 1-5 described first receiving portion 12 and second receiving portion 14 made.
  • the base 4 is manufactured.
  • the base 4 is made with a metal wall 24 and the bottom 23 of an electrically insulating material, for example plastic.
  • the bottom 23 of the base 4 is provided with at least one opening 22 for a conductor wire.
  • at least one electronic device 12 is accommodated in the second receiving section 14.
  • the adapter 1 is then inserted into the socket 4 with the electronic device 12 accommodated in the second receiving section 14.
  • a lead wire 21 of the electronic device 12 for example, between the outside or outer wall of the second receiving portion 14 and the metal wall 24 of the base 4 are led to the electrical connection to the outside.
  • the invention is not limited to this arrangement of the lead wire 21.
  • the base 4 is connected to the adapter 3 and the at least one electronic device 12 connected to the lamp bulb 2.
  • the first receiving portion 13 of the adapter 3 is inserted into the tubular recess 6 of the lamp bulb 2 and the first receiving portion 13 with the tubular recess 6 by gluing, positive engagement and / or adhesion.
  • the sleeve 25, if present, are glued to a portion of the outside of the lamp envelope 2.
