Abstract

A device for mounting lighting sources on a substrate includes a channel-like mounting frame provided with fixing formations for fixing on said substrate, said mounting frame defining a cavity for receiving said lighting source with said lighting source resting on said substrate, a slider member which can be positioned in said cavity of said mounting frame to urge said lighting source toward said substrate; said slider member being slidable with respect to said mounting frame between an insertion position and a locking position, wherein said mounting frame and said slider member bear complementary engagement formations cooperating in a ramp-like manner to force said slider member and the lighting source urged thereby toward said substrate when said slider member is advanced from said insertion position toward said locking position.

Claims

1. A device for mounting lighting sources on a Substrate, comprising:

a channel-like mounting frame provided with fixing formations for fixing on said substrate, said mounting frame defining a cavity for receiving said lighting source with said lighting source resting on said substrate,

a slider member which can be positioned in said cavity of said mounting frame to urge said lighting source toward said substrate;

said slider member being slidable with respect to said mounting frame between an insertion position and a locking position, wherein said mounting frame and said slider member bear complementary engagement formations cooperating in a ramp-like manner to force said slider member and the lighting source urged thereby toward said substrate when said slider member is advanced from said insertion position toward said locking position.

2. The device as claimed in claim 1, wherein said complementary engagement formations comprise:

at least one ramp-like cavity, and

at least one pin engaging said at least one ramp-like cavity, said ramp-like cavity and said pin being carried by said mounting frame and by said slider member, respectively

3. The device as claimed in claim 1, wherein said fixing formations comprise at least one resilient member which resiliently forces said mounting frame toward said substrate.

4. The device as claimed in claim 3, wherein said resilient member includes an elastic member such as a spring.

5. The device as claimed in claim 1, wherein said fixing formations include screws or rivets extending between said mounting frame and said substrate.

6. The device as claimed in claim 1, wherein said slider member has lateral branches extending into the cavity of said mounting frame to urge said lighting source toward said substrate.

7. The device as claimed in claim 1, wherein said slider member includes a window portion permitting propagation of the light radiation produced by said lighting source.

8. The device as claimed in claim 1, wherein said mounting frame has a thickness whereby, when it is fixed on said substrate, said mounting frame is exempt from contact with said substrate.

9. The device as claimed in claim 1, wherein said slider member bears scraping contacts for electrical contact with said lighting source.

10. The device as claimed in claim 1, wherein said substrate is a heat sink.
