Abstract:
1. An LED illumination device for generating uniform stripped light source, comprising: a stripped light-guiding unit having a light-guiding body and a plurality of first light-guiding microstructures disposed on a top side of the light-guiding body, wherein the light-guiding body has at least two first retaining portions, and each first light-guiding microstructure has a first reflective index; a stripped reflective unit having a reflective body corresponding to the light-guiding body and a reflective layer formed on an inner surface of the reflective body, wherein the stripped reflective unit covers one part of the light-guiding body, the first light-guiding microstructures are disposed between the light-guiding body and the reflective layer, and the reflective layer has a second reflective index that is different from the first reflective index; a fixing unit having at least one fixing body and at least two second retaining portions extended downwards from the fixing body, wherein the position of the stripped light-guiding unit relative to the fixing unit is fixed by matching the two first retaining portions and the two second retaining portions; and a light-emitting unit having a first light-emitting module disposed beside one end of the light-guiding body.
