  • Another object of the present invention is to provide such a lighting device that is reliable and at the same time easy to assemble and to produce.
  • the lighting device for illuminating objects according to the invention comprises:
  • the angle of incidence of the light on the secondary optical assembly can be varied, so as to obtain various configurations of light beams leaving the secondary optical assembly of the lighting device, according to the lighting requirements.

  • the light sources used in the lighting device 1 are LED (light emitting diodes).
  • the single LED 20 comprises an emitter 21 consisting of a chip of a solid-state device.
  • Two metal terminals 22 are connected to the emitter 21 for the electrical supply.
  • the LED 20 (of the Lambertian type), due to its morphology, emits light around its optical axis, according to a cone having an angle of aperture ⁇ of about 140°.
  • the LED 20 used has a high light intensity and can have a power of 1-3 W or greater, according to availability on the market.

  • Two LEDs 20 are mounted side by side, in a central position, on the circuit board 2 and are disposed along the midline of the board 2. As shown in Figure 4 , the LEDs 20 are equidistant from the respective side edges of the board and the distance D between the optical axes of the emitters of the LEDS 20 is about 14 mm.
  • optical axis is used hereunder to indicate the axis passing through the centre of the light input surface of the lens and at right angles to the plane tangent to the centre of said light input surface.
  • the LEDS 20 are soldered on the board 2 and are connected to each other in series. That is to say, two terminals 22 of two LEDs 20 are connected to each other, whilst the other two terminals 22 of the LEDs are connected to respective conductive tracks (24, 24') formed on the circuit board 2.
  • the conductive tracks (24, 24') lead towards a corner of the circuit board 2 to be connected respectively to the positive pole (+) and to the negative pole (-) of an electrical supply device, which supplies both LEDs 20 at the same time.

  • two further holes 27 are formed in the board 2 for mounting thereof on the heat sink 4 or on the body 5.
  • the light emitted by the LEDs 20 is not sufficient to provide adequate illumination. For this reason the LEDs 20 must be coupled to respective primary optical assemblies 3, which serve to amplify the light emitted by the LEDs 20 and to direct it in the desired direction.

  • the tongues 34 of the cradles 31 are fixed in the holes 26 distinguished by the letter "L".

  • the distance A1 between the optical axis of the left-hand LED 20 (with reference to Figure 9 ) and the optical axis of the respective coupled primary lens 30 is about 0.5 mm
  • the distance A2 between the optical axis of the right-hand LED 20 (with reference to Fig. 9 ) and the optical axis of the respective coupled primary lens 30 is about 0.3 mm.
  • the centre distance I between the two primary lenses 30 is about 13.8 mm.
  • the emitters of the LEDs 20 are out of axis with respect to the primary lenses 30, the cones of light emitted by the two LEDs 20 are deviated when they meet the respective primary lenses 30.
  • the primary lenses 30 generate light beams with a slight inclination towards the right (with reference to Fig. 9 ) with respect to their optical axis.
  • the beam leaving the first primary lens will have a greater inclination with respect to the beam leaving the second primary lens, since the distance A1 between the axis first of the primary lens and the axis of the respective LED is greater than the distance A2 between the axis of the second primary lens and the axis of the respective LED.

  • Holes 43 are formed in the flat front wall of the heat sink 4 to receive fixing screws of the circuit board 2.

  • the primary lenses 30 are mounted off-centre with respect to the respective LEDs 20 so as to generate an optical beam for both light sources deviated in the direction of the optical axis O of the cylindrical secondary lens 6. In this manner a light beam whose section assumes a shape of a so-called "blade of light” will leave the secondary lens.
  • the lighting device 1 according to the first embodiment of the invention can be used in wall or corner mounting, alone or in combination with other lighting devices of the same type.

  • the lighting device 101 can be mounted tiltingly in a substantially U-shaped support bracket 7.
  • the support bracket 7 comprises a base 70 from which two support plates 71 protrude. Respective holes 73 in which the two protruding tongues 42 of the heat sink 4 are pivoted are formed in the support plates 71.
  • the lighting device can rotate around the axis passing through the two protruding tongues 42 of the heat sink, which is parallel to the axis Y passing through the two optical axes of the two primary lenses 30.

  • a lighting device 201 according to a third embodiment of the invention is described with reference to Figures. 20 - 24 .
  • the only change with respect to the second embodiment is represented by the fact the circuit board 2 supporting the LEDs 20 and the primary optical assemblies 3 is rotated 90° with respect to the position illustrated in the second embodiment and thus the circuit board 2 is applied on the heat sink 4.

  • the lighting device 201 can be used to generate symmetrical light beams with different apertures on the two planes of projection (tangential plane of projection and sagittal plane of projection). These light beams generated by the lighting device 201 are commonly called wall-washers.
  • FIG 25 a lighting device 301 according to a fourth embodiment of the invention is illustrated.
  • the lighting device 301 has a configuration similar to that of the lighting device 101 of the second embodiment.
  • the cylindrical secondary lens 6 is replaced by a flat secondary lens 306 of transparent glass.
  • the beam emitted by the lighting device 301 will have a cone-shaped angular aperture with its apex near the output plane of the flat secondary lens 306.
  • the angular aperture of the light beam will depend upon the position of the primary optical assembly 3 with respect to the secondary lens 306. The smaller the distance between the primary optical assembly 3 and the secondary lens 306, the greater the angular aperture of the conical light beam.
