Abstract
In an LED device, a light guide array is disposed between a planar LED array light source and a curved housing. A first surface of the light guide array is a plane evenly distanced from the LED array and a second surface of the light guide array is a curved surface evenly distanced from the curved housing. A plurality of guiding channels, either one-to-one or one-to-many to the LED, are aligning along each light axis of the LED in the light guide array, whose reflective surface allows the lights emitted by each LED to reflect thereon and emit from the second surface and simulate a curved light source having substantially the same shape as the curved housing.
