Abstract

A semiconductor lamp comprises a housing in which a driver is accommodated and at least one contact pin protruding from the housing outwards, wherein the contact pin is tubular and riveted to the housing and the driver is connected to the contact pin via an electrically conductive connection element which is inserted into a cavity of the contact pin. A method serves for producing a semiconductor lamp, wherein at least one tubular contact pin is inserted into a feedthrough of a housing from outside till the contact pin abuts the housing, the contact pin is next riveted with the housing on the inside and a driver is inserted into the housing, whereby an electrically conductive connection element is inserted into the contact pin. The invention is particularly applicable to LED retrofit lamps for replacing bipin halogen lamps, in particular MR16 lamps.

First claim

The invention claimed is:

1. A semiconductor lamp, comprising
a housing in which a driver is accommodated, and
at least one contact pin protruding from the housing outwards, wherein
the contact pin is a tubular contact pin riveted to the housing,
the driver is connected to the contact pin via an electrically conductive connection element which is inserted into a cavity of the contact pin,
the housing has a respective feedthrough provided for each contact pin and the feedthrough is widened at an inside portion, and
a space between the widened portion of the feedthrough and the contact pin is at least partially filled with a reshaped material of the contact pin.

2. The semiconductor lamp according to claim 1 , wherein the contact pin comprises a laterally protruding flange which rests on the outside of the housing.

3. The semiconductor lamp according to claim 1 , wherein the cavity of the contact pin is formed like a funnel at a side facing the driver.

4. The semiconductor lamp according to claim 1 , wherein the electrically conductive connection element is a contact wire.

5. The semiconductor lamp according to claim 1 , wherein the electrically conductive connection element is fastened on the contact pin.

6. The semiconductor lamp according to claim 1 , wherein the contact pin comprises at least one hole laterally leading to the cavity at a portion of the contact pin arranged outside the housing.

7. The semiconductor lamp according to claim 1 , wherein the semiconductor lamp has a bipin base.

8. The semiconductor lamp according to claim 7 , wherein the semiconductor lamp is a MR16 replacement lamp.

9. The semiconductor lamp according to claim 1 , wherein the cavity of the contact pin is closed at an outer side facing away from the driver.

10. A method for producing a semiconductor lamp according to claim 1 , comprising the steps of:
inserting at least one tubular contact pin into a feedthrough of a housing from the outside till the contact pin abuts the housing,
riveting the contact pin with the housing on the inside, and
inserting a driver into the housing, whereby an electrically conductive connection element is inserted into the contact pin,
wherein the housing has a respective feedthrough provided for each contact pin and the feedthrough is widened at an inside portion, and
wherein a space between the widened portion of the feedthrough and the contact pin is at least partially filled with a reshaped material of the contact pin after the riveting.

11. The method according to claim 10 , further comprising fastening the connection element inserted into the contact pin to the contact pin.

12. A semiconductor lamp, comprising
a housing in which a driver is accommodated, and
at least one contact pin protruding from the housing outwards, wherein
the contact pin is a tubular contact pin riveted to the housing,
the driver is connected to the contact pin via an electrically conductive connection element which is inserted into a cavity of the contact pin, and
the contact pin comprises at least one continuous hole laterally leading to the cavity at a portion of the contact pin arranged outside the housing.
