Automotive lamp provided with a bulb locked to the cap of the lamp

1. An automotive lamp comprising:

a bulb containing a light source;

a cap that receives a portion of the bulb such that the cap engages the bulb by a click connection; and

a connection member that receives the cap including the bulb and connects the lamp to a lamp holder,

wherein the connection member is non-detachably connected to the cap and locks the click connection and the bulb cannot be removed from the cap after insertion of the bulb in the cap and insertion of the cap in the connection member.

2. The automotive lamp as claimed in claim 1 , wherein the connection member is secured to the cap by glue.

3. The automotive lamp as claimed in claim 1 , wherein the connection member is secured to the cap by weld.

4. The automotive lamp as claimed in claim 1 , wherein the connection member is connected to the cap an ultrasonic weld.

5. The automotive lamp as claimed in claim 1 , wherein the cap is formed as one single part of resilient material.

6. The automotive lamp as claimed in claim 1 , wherein the connection member surrounds a main portion of the cap.

7. The automotive lamp as claimed in claim 1 , wherein the connection member carries key elements so that the connection member uniquely matches the lamp holder.

8. The automotive lamp as claimed in claim 1 , wherein the connection member has a substantially a shape of a tube, the cap being present at one end of the tube, and a connector element can be inserted into another end of the tube in order to make electrical contact with lead wires of the lamp.

9. The automotive lamp as claimed in claim 1 , wherein an annular wall of the cap includes slits and wherein the slits are shifted in a tangential direction with respect to an axis, an extent of the shift being such that wall parts of the annular wall form three-dimensional, less-flexible annular click parts of the cap, and that viewed in radial direction there is an overlap in tangential direction of a wall of the connection member with the click parts.

10. A method of assembling an automotive lamp comprising the acts of:

inserting a bulb containing a light source in a cap that surrounds a portion of the bulb such that the cap engages the bulb by a click connection;

inserting the cap including the bulb in a connection member; and

permanently fixing the cap to the connection member for non-detachably connecting the connection member to the cap and locking the click connection,

wherein after the permanently fixing act, the bulb cannot be removed from the cap.

11. The automotive lamp of claim 1 , wherein the cap includes walls including a portion of the click connection and having slits for allowing deformation of the walls when the bulb is inserted in the cap to move away from the bulb when the bulb in inserted in the cap, and wherein the walls of the cap are non-detachably connected to the connection member after insertion of cap including the bulb in the connection member to prevent the deformation of the walls including preventing removal of the bulb from the cap and preventing removal of the cap from the connection member.

12. The method of claim 10 , wherein the permanently fixing act includes gluing the cap to the connection member.

13. The method of claim 10 , wherein the permanently fixing act includes soldering the cap to the connection member.

14. The method of claim 10 , wherein the cap includes walls having slits for allowing deformation of the walls to move away from the bulb when the bulb in inserted in the cap, and wherein the permanently fixing act non-detachably connects the walls to the connection member to prevent the deformation of the walls including preventing removal of the bulb from the cap and preventing removal of the cap from the connection member.
