Abstract

A component of a generally cylindrical luminous signaling column housing plural conductors that are substantially parallel to the axis of the cylinder and a printed circuit bearing plural LED luminous sources. The printed circuit is oriented such that its main plane is parallel to the axis of the component and bears plural LEDs on each surface. The cylindrical luminous signaling column includes a cylindrical inner surface provided with light-diffusing reliefs.

Claims

1. A component of a luminous signaling column, said component being generally cylindrical in shape and housing plural conductors substantially parallel to the axis of the cylinder, comprising:

a printed circuit bearing plural LED light sources, the printed circuit having a single main plane and two opposite surfaces, wherein the printed circuit is oriented such that its main plane is parallel to the axis of the cylinder and bears plural LEDs on each of the two opposite surfaces, and

at least two plates not integral with the printed circuit, each respectively bearing a conductor, that interconnect neighboring components of the column, the two plates being coplanar with the printed circuit.

2. A component of claim 1, wherein an inner surface of the cylinder is covered in light-diffusing reliefs.

3. A component of claim 2, wherein the light-diffusing reliefs are grooves parallel to the axis of the cylinder.

4. A component of claim 1, wherein the two plates and the printed circuit are located in a diametral plane of the component.

5. A component of claim 1, wherein the printed circuit is disposed diametrically between the two plates, one of the two plates supporting individual interconnecting conductors and the other of the two plates supporting a common conductor.

6. A component of claim 1, wherein the two plates and the printed circuit are fastened to a disk-shaped or crown-shaped structure that nests inside the component.

7. A component of claim 1, wherein the printed circuit is housed inside a bulb.
