## Abstract

Lighting modules are provided having a reflector which includes a central part and two tilted wings with respect to said central part, and at least two light sources, or light source assemblies, arranged about the ends of said central part. Lighting apparatuses which include such lighting modules are also provided.

## Claims

### Claim at position 1

1-22. (canceled)

### Claim 23

A lighting module comprising a reflector which comprises a central part and two tilted wings with respect to said central part, and at least two light sources, or light source assemblies, arranged about the ends of said central part wherein that said two light sources or light source assemblies arranged about the ends of said central part are oriented, with respect to a reference C/γ coordinate system, according to an angle C between about 0° and about 30° and according to an angle C between about 150° and about 180°, and according to an angle γ, in relation to the vertical, between about 50° and about 90°, respectively.

### Claim 24 (depends on 23)

The lighting module of claim 23, comprising a third light source or light source assembly arranged about the middle point of said central part.

### Claim 25 (depends on 24)

The lighting module of claim 24, wherein said third light source, or light source assembly, is oriented according to an angle C between about 0° and about 360° and to an angle γ between about 0° and about 45°.

### Claim 26 (depends on 23)

The lighting module of claim 23, wherein said light sources or light source assemblies are aligned.

### Claim 27 (depends on 23)

The lighting module of claim 23, wherein said point light sources comprise LEDs.

### Claim 28

The lighting module of 27, wherein said LEDs are characterized by an emission cone having a width between about 50° and about 150°.

### Claim 29 (depends on 23)

The lighting module of claim 23, wherein said light sources or light source assemblies comprise appropriate means for optimizing the emission thereof along preferred directrices selected from the group comprising concentrators, reflectors, TIR (Total Internal Reflection) lenses, Fresnel lenses and any combination thereof

### Claim 30 (depends on 23)

The lighting module of claim 23, wherein said light sources or light source assemblies comprise piloting devices to independently control the light emission of said light sources or light source assemblies, thus allowing the overall resulting illumination to be modulated.

### Claim 31 (depends on 23)

The lighting module of claim 23, wherein said light sources or light source assemblies comprise an orientation component adapted to vary the inclination thereof

### Claim 32 (depends on 31)

The lighting module of claim 31, wherein said orientation component comprises a supporting plate for said light sources or said light source assemblies, associated with said reflector a coupling component capable of allowing variation of the orientation thereof and therefore the orientation of the emitted light beam.

### Claim 33 (depends on 32)

The lighting module of claim 32, wherein said appropriate coupling component comprises at least one hinge adapted to allow the rotation of said plate about its axis.

### Claim 34 (depends on 33)

The lighting module of claim 33, wherein said appropriate coupling component comprises at least one spherical joint.

### Claim 35 (depends on 23)

The lighting module of claim 23, wherein said tilted wings comprise a bend.

### Claim 36 (depends on 23)

The lighting module of claim 23, wherein said tilted wings comprise more than one segment.

### Claim 37 (depends on 36)

The lighting module of claim 36, wherein said more than one segment comprises inclinations and/or bends different from one another.

### Claim 38 (depends on 23)

The lighting module of claim 23, wherein said tilted wings of said reflector comprise inclinations of about 30° and about 90°, respectively, with respect to said central part.

### Claim 39 (depends on 23)

The lighting module of claim 23, wherein said reflector comprises plastic material or metal.

### Claim 40 (depends on 23)

The lighting module of claim 23, wherein said reflector comprises aluminium.

### Claim 41 (depends on 23)

A lighting apparatus comprising a plurality of lighting modules according to claim 23.

### Claim 42 (depends on 41)

The lighting apparatus of claim 41, further comprising a plurality of point light sources arranged in an array on the side of said lighting apparatus parallel to said tilted wings.

### Claim 43 (depends on 42)

The lighting apparatus of claim 42, wherein said plurality of point light sources arranged in an array are arranged on the side corresponding to the smaller wing of said tilted wings.
