View Patent ↗An end piece for a retrofit fluorescent lamp may include a housing section open on a first end face and a cover that can close off the first end face, wherein the housing section and the cover can be non-detachably interlocked.
1. An end piece for a retrofit fluorescent lamp, the end piece comprising:
a housing section open on a first end face and a cover that is configured to close off the first end face,
wherein the housing section and the cover are configured to be non-detachably interlocked,
wherein at least two projecting locking hooks are present on the first end face of the end piece and the cover has corresponding locking recesses.
2. The end piece as claimed in claim 1 , wherein the locking recesses are not freely accessible.
3. The end piece as claimed in claim 1 , wherein the end piece has at least two pairs of locking hooks projecting from the end face.
4. The end piece as claimed in claim 1 , wherein the locking recesses are covered by a ring.
5. The end piece as claimed in claim 1 , wherein at least one projecting coding element is present on the first end face of the end piece and the cover has at least one corresponding coding element recess.
6. The end piece as claimed in claim 5 , wherein the coding element is implemented in the form of a triangle.
7. The end piece as claimed in claim 6 , wherein the coding element is implemented in the form of a triangle with a flattened apex.
8. The end piece as claimed in claim 1 , wherein the housing section has, on its second end face opposite the first end face, at least one plug pin for insertion in a heat sink.
9. The end piece as claimed in claim 8 , wherein the plug pin has an essentially circular segment shaped outside contour in the insertion direction.
10. The end piece as claimed in claim 8 , wherein the plug pin has at least one screw bushing running at right angles to the insertion direction.
11. A retrofit fluorescent lamp, comprising: an end piece, the end piece comprising:
a housing section open on a first end face and a cover that is configured to close off the first end face,
wherein the housing section and the cover are configured to be non-detachably interlocked,
wherein at least two projecting locking hooks are present on the first end face of the end piece and the cover has corresponding locking recesses.
12. The retrofit fluorescent lamp as claimed in claim 11 , wherein the end piece accommodates a driver.
13. The retrofit fluorescent lamp as claimed in claim 11 , wherein it has a hollow heat sink extending lengthwise along a longitudinal axis of the retrofit fluorescent lamp, wherein a shape of the inside contour of the heat sink essentially corresponds to the shape of the outside contour of the plug pin.
14. The retrofit fluorescent lamp as claimed in claim 11 , wherein the heat sink has at least one screw hole which can be made to coincide with the screw bushing of the plug pin.
15. The retrofit fluorescent lamp as claimed in claim 11 , wherein the retrofit fluorescent lamp is configured as a light emitting diode retrofit fluorescent lamp.
