Coupling component for lighting devices
View Patent ↗A coupling component has a groove for receiving a rim of a mouth portion of a lighting body protection bulb. The groove includes sculptured formations to keep the mouth portion rim received in the groove spaced from the bottom of the groove to produce a discontinuous contact between the mouth portion rim and the groove.
1. A coupling component configured to hold a lighting body inserted in a protection bulb via a mouth portion of the bulb, said component comprising a groove for receiving the rim of said mouth portion of said bulb, said groove including sculptured formations to keep said mouth rim received in said groove spaced from the bottom of said groove to produce a circumferentially discontinuous contact between said mouth rim and said groove.
2. The component as claimed in claim 1 , configured such that said sculptured formations are ribs emerging from said groove.
3. The component as claimed in claim 1 , wherein said groove is shaped to be couplable to support elements for said lighting body in said bulb.
4. The component as claimed in claim 1 , configured such that said groove lies between two annular walls of said component.
5. The component as claimed in claim 1 , connected to said bulb via gluing or mechanical coupling.
6. The component as claimed in claim 1 , made from a heat-resistant plastics material.
7. The component as claimed in claim 6 , wherein the heat-resistant plastics material is LCP material.
8. The component as claimed in claim 1 , said sculptured formations including ventilation openings to permit air flow with respect to the interior of said bulb.
9. The component as claimed in claim 8 , having an try-like shape with a bottom wall with said ventilation openings provided in said bottom wall.
10. The component as claimed in claim 8 , with said ventilation openings angularly distributed around the component.
