Light collecting and guiding machine

The invention discloses a light collecting and guiding machine. The machine comprises at least one light guiding unit, wherein the light guiding unit comprises a flat light guiding part and a light collecting part. The light guiding part comprises two first light guiding surfaces arranged at intervals, two second light guiding surfaces connected with the first light guiding surfaces, and a light guiding inlet surface and a light guiding outlet surface aligned at intervals. The light collecting part comprises a light collecting inlet surface, and a light collecting outlet surface towards the light guiding inlet surface. After a light ray passes through the light collecting inlet surface, the light collecting outlet surface and the light guiding inlet surface to enter the light guiding part, the light ray is transferred by the light guiding part and finally emitted by the light guiding outlet surface. As the light guiding unit is flat, a spot light source can be guided to a strip surface light source so as to accord with use requirements. The machine can extend along the edge of a lamp to facilitate to intensity the edge shape of the lamp.
