Abstract

A lighting appliance (1) comprises a light module (2) having a base (6) designed to receive a handle (5) provided with a grip stick (10), the handle (5) being arranged such that it can be inserted axially in removable manner into a ring (7, 7′) arranged on the base (6). The handle (5) is withdrawn axially from the base (6) by turning the ring (7, 7′) relative to the base (6).

Claims

1. A lighting appliance comprising a light module having a base configured to receive a handle provided with a grip stick, said handle being arranged such that it can be inserted axially in removable manner into a ring arranged on said base, wherein said handle is withdrawn axially from said base by turning said ring relative to said base.

2. The lighting appliance according to claim 1, wherein a latch is received in said ring for the purpose of locking and unlocking said handle in said base.

3. The lighting appliance according to claim 2, wherein said latch is provided with at least one retractable cam.

4. The lighting appliance according to claim 3, wherein said latch is provided with two cams mounted on springs so that said springs press said cams so as to lock said handle in said base, and so that, when said ring is turned, said springs are compressed by said cams as pushed by lugs arranged on the inside surface of said ring.

5. The lighting appliance according to claim 2, wherein said latch is provided with at least one retractable stud extending radially in said ring.

6. The lighting appliance according to claim 5, wherein said latch is provided with three studs mounted on springs so that said studs project into said ring to lock said handle in said base and so that, when said ring is turned, said studs are in a retracted position in which they are retracted into respective recesses arranged in the inside surface of said ring.

7. The lighting appliance according to claim 6, wherein said handle is provided with a fastening head having a positioning protuberance of convex shape for positioning in said ring, said protuberance having an annular groove arranged to co-operate with said latch.

8. The lighting appliance according to claim 7, wherein said handle is sterile.

9. The lighting appliance according to claim 8, wherein an electrical appliance is received in said handle, and in that means for electrically powering and monitoring/controlling said electrical appliance are arranged on said handle and on said base.

10. The lighting appliance according to claim 3, wherein said handle is provided with a fastening head having a positioning protuberance of convex shape for positioning in said ring, said protuberance having an annular groove arranged to co-operate with said latch.

11. The lighting appliance according to claim 2, wherein said handle is provided with a fastening head having a positioning protuberance of convex shape for positioning in said ring, said protuberance having an annular groove arranged to co-operate with said latch.

12. The lighting appliance according to claim 1, wherein said handle is provided with a fastening head having a positioning protuberance of convex shape for positioning in said ring, said protuberance having an annular groove arranged to co-operate with said latch.

13. The lighting appliance according to claim 3, wherein said handle is sterile.

14. The lighting appliance according to claim 2, wherein said handle is sterile.

15. The lighting appliance according to claim 1, wherein said handle is sterile.

16. The lighting appliance according to claim 3, wherein an electrical appliance is received in said handle, and in that means for electrically powering and monitoring/controlling said electrical appliance are arranged on said handle and on said base.

17. The lighting appliance according to claim 2, wherein an electrical appliance is received in said handle, and in that means for electrically powering and monitoring/controlling said electrical appliance are arranged on said handle and on said base.

18. The lighting appliance according to claim 1, wherein an electrical appliance is received in said handle, and in that means for electrically powering and monitoring/controlling said electrical appliance are arranged on said handle and on said base.
