Abstract

A lamp for a saddle-ride type vehicle includes a casing having a front aperture and a light source attached to the casing. A reflector is configured to reflect the light emitted by the light source, and a diffuser is arranged in front of the reflector. A clear cover attaches to the casing and defines, together with the casing, a space in which the light source, the reflector, and the diffuser are arranged. The diffuser is shaped to include mutually alternating ridges and valleys. A vehicle of the type with a saddle includes the lamp.

First claim

The invention claimed is:

1 . A lamp for a saddle-ride type vehicle comprises:
a casing comprising a front aperture; a light source attached to the casing; a reflector configured to reflect light emitted by the light source; a diffuser arranged in front of the reflector; a clear cover attached to the casing and configured to define together with the casing a space in which the light source, the reflector and the diffuser are arranged; wherein the diffuser is shaped to comprise a plurality of ridges and valleys alternated with each other; wherein the diffuser comprises a transparent material including matt transparent portions and glossy transparent portions; the matt transparent portions are on the valleys and the glossy transparent portions are on the ridges.

2 . The lamp according to claim 1 , wherein at least one of the ridges comprises a protuberance shaped to extend outward from the ridge.

3 . The lamp according to claim 2 , wherein an external surface of the protuberance is matt transparent.

4 . The lamp according to claim 2 , wherein the protuberance has a tapered shape.

5 . The lamp according to claim 2 , wherein the protuberance has a prismatic shape.

6 . The lamp according to claim 1 , wherein the ridges are linear ridges and/or the valleys are linear valleys.

7 . The lamp according to claim 1 , wherein the light source comprises a plurality of light spots and the reflector comprises a plurality of reflecting surfaces associated to said light spots.

8 . The lamp according to claim 7 , wherein the light source has a flat body, and the light spots are attached to one side of the flat body or to two opposite sides of the flat body.

9 . The lamp according to claim 8 , wherein the reflector comprises a transversal septum shaped to separate a first group of reflecting surfaces associated to a first group of light spots from a second group of reflecting surfaces associated to a second group of light spots.

10 . The lamp according to claim 9 , wherein the first group of light spots is configured to emit a colored light beam and the second group of light spots is configured to emit a white light beam.

11 . The lamp according to claim 7 , wherein the light spots comprise LEDs, and wherein the light source has a flat body, and the light spots are attached to one side of the flat body or to two opposite sides of the flat body.

12 . The lamp according to claim 1 , wherein the clear cover is configured to entirely cover and to close the front aperture of the casing in a water-proof manner.

13 . The lamp according to claim 1 , wherein the casing comprises an inner reflecting surface and attaching means for connecting the lamp to a vehicle.

14 . The lamp according to claim 1 , wherein the lamp comprises a turn signal lamp.

15 . A saddle-ride type vehicle comprising at least one lamp according to claim 1 .
