The invention concerns an LED lighting electric device (1) comprising:
- an LED light source (2) mounted and powered on a support card (15);
- a corresponding inverted truncated cone-shaped waveguide (3) associated with the light source (2) to diffuse the light beam generated by said source;
- a lens (4) supported in a predetermined spaced apart relationship with the light source (2);
- transparent support legs (5) formed in one piece with the waveguide (3) and base ends (7) proximal to the light source (2) fixed to the card (15) around the light source (2). Advantageously, according to the invention, the base ends (7) of the transparent legs (5) are in contact with a resin (9) that does not absorb light radiation. In this way, a saturation effect of the light beam taken away through the support legs of the waveguide is achieved and the luminosity of the LED lighting device (1) is increased for an equal level of electrical power consumption. |
