Abstract: An LED indicating device, in particular for a vehicle instrument cluster, has a plate provided with at least one light permeable portion adapted to be illuminated by a plurality of LED sources arranged in a position spaced apart from such a rear surface of such a light permeable portion; the device has a body which is arranged between the LED sources and the rear surface of the light permeable portion and has a first surface facing the LED sources and a second surface facing the rear surface; the body consists of a matrix made of a light impermeable material and of a plurality of light permeable elements, which are embedded in the matrix in positions spaced apart from one another and continuously extend from the first surface to the second surface.

Abstract: An instrument cluster, in particular for a vehicle, has a dial with a plurality of graphic areas, which are backlit by a device provided with at least one light source, with a front light-guiding element having a front face at least partially covered by a back surface of the dial, and with a rear light-guiding element; the latter has a receiving portion facing said light source and a transmitting portion, which transmits and guides the light received by the receiving portion and is spaced apart from and faces a rear face of the front light-guiding element; the rear face of the front light-guiding element has an optical compensation system, having curved convex or curved concave lens surfaces, for varying the intensity of the light transmitted from said transmission portion to the different graphic areas.
