A light pipe may be used to illuminate an elongated area. Light may emanate laterally relative to the axis of the light pipe, and the light intensity is substantially uniform along the length of the light pipe. The light pipe may include a translucent member and a opaque reflective member that is separated from the translucent member by an air gap. A band of reflective material may be located on an exterior surface of the translucent member. The entire light pipe may be formed by co-extrusion of the translucent member, the band of reflective material and the opaque section through a single co-extrusion die. Light emitted laterally from the translucent member toward the arcuate opaque reflective member and band of reflective material may be reflected laterally through the translucent member transverse to the axis of the light pipe, so that all light extends through the front surface of the translucent member.

L'invention concerne un conduit de lumière pouvant être utilisé en vue d'éclairer une zone de forme allongée. Cette lumière émane latéralement par rapport à l'axe du conduit de lumière, et l'intensité de lumière est sensiblement uniforme le long de la longueur du conduit. Le conduit de lumière comprend un élément translucide et un élément réfléchissant opaque séparé de l'élément translucide par un espace. Une bande de matériau réfléchissant peut être placée sur une surface externe de l'élément translucide. L'ensemble du conduit de lumière peut être formé par co-extrusion de l'élément translucide, de la bande de matériau réfléchissant et de la section opaque par le biais d'une filière de co-extrusion unique. La lumière émise latéralement à partir de l'élément translucide en direction de l'élément réfléchissant opaque arqué et la bande de matériau réfléchissant peuvent être réfléchis latéralement à travers l'élément translucide de façon transversale par rapport à l'axe du conduit de lumière, de sorte que toute la lumière s'étende à travers la surface frontale de l'élément translucide.
