  • a complete replacement of all components is not required for later replacement of the lamp head or the lighting means of the downlight, but it is sufficient if only the light carrier is detached from the mounting frame and removed.
  • the mounting frame itself can remain permanently on the ceiling.
  • Lamp head again has adjustment and, for example, can be pivoted against this and / or rotated. Often come so-called gimbal lights are used, in which the lamp head with respect to the light carrier rotatable by 360 ° and in addition also pivots. Although the storage of the

This means that there is a risk that when adjusting the orientation of the lamp head accidentally also the light carrier is released and the lamp falls out of the mounting frame.

  • the fact that this is a flexible element also ensures that the locking spring, after passing the ramp, automatically jumps to a position in which, in accordance with the present invention, the light carrier is secured against rotation in the unlocking direction.

  • this lock can be solved, including, for example, be provided that on the mounting frame an unlocking is formed, which allows the insertion of a tool for lifting the locking spring.
  • This opening can be very narrow, so that only by a very narrow object such as a paper clip or a narrow screwdriver, which must be specifically introduced into this opening, the lock can be solved.
  • this measure provides sufficient security; on the other hand, the effort required to release the lock, if the light carrier is deliberately to be removed from the mounting frame, is not very high.
