An illuminated emblem for a vehicle comprising: - a front element with the shape of a logotype, where the front element is opaque, and the inner face of the front element is of a color that reflects light; - a rear casing for fixing the emblem to a portion of the vehicle body, where the rear casing is opaque, and where the inner surface of the rear casing is of a color that reflects light; - a light diffusion filter arranged between the front element and the rear casing , where the inner space defined by the front element , the rear casing and the diffusion filter defines a cavity , where the contour of the diffusion filter reproduces the same perimetral shape as the perimetral edge of the front element , wherein the diffusion filter is translucent and configured to allow light to be extracted from the cavity ; and - at least one illumination circuit arranged inside the cavity , where the at least one illumination circuit comprises a plurality of light sources ; where the inner face of the front element and the inner surface of the rear casing generate an internal reflection chamber for the light beams emitted by the plurality of light sources , and where the light escapes from the cavity through the diffusion filter only in the lateral direction, generating an indirect illumination of the perimeter of the emblem on the vehicle body; characterized in that the cavity does not include a light guide in combination to the internal reflection chamber generated by the inner face of the front element and the inner surface of the rear casing , and the cavity functions as an internal reflection chamber for the light beams emitted by the plurality of light sources and the light beams are made to internally bounce around constantly since they are reflected as they strike the reflective inner walls of the rear casing and the front element , thereby filling the entire cavity with light. - a front element with the shape of a logotype, where the front element is opaque, and the inner face of the front element is of a color that reflects light; - a rear casing for fixing the emblem to a portion of the vehicle body, where the rear casing is opaque, and where the inner surface of the rear casing is of a color that reflects light; - a light diffusion filter arranged between the front element and the rear casing , where the inner space defined by the front element , the rear casing and the diffusion filter defines a cavity , where the contour of the diffusion filter reproduces the same perimetral shape as the perimetral edge of the front element , wherein the diffusion filter is translucent and configured to allow light to be extracted from the cavity ; and - at least one illumination circuit arranged inside the cavity , where the at least one illumination circuit comprises a plurality of light sources ; where the inner face of the front element and the inner surface of the rear casing generate an internal reflection chamber for the light beams emitted by the plurality of light sources , and where the light escapes from the cavity through the diffusion filter only in the lateral direction, generating an indirect illumination of the perimeter of the emblem on the vehicle body; <EOS>
