REFLECTIVE HOUSING AND LED ILLUMINATOR USING SAME

摘要

An exemplary reflective housing for a LED illuminator is provided. The reflective housing includes a plurality of side walls cooperatively forming a hollow shell. The hollow shell has a first opening and a second opening opposite to the first opening. The hollow shell tapers from the first opening to the second opening. Inner surfaces of the side walls are light reflective surfaces. The first opening has a polygonal shape having more than four sides. The first opening includes two parallel sides. Four endpoints of the first opening cooperatively form an imaginary quadrangle. Remaining sides are located at an exterior of the imaginary quadrangle. A line segment obtained by intersecting any straight lines parallel to the parallel sides is shorter than a distance between the two parallel sides. The second opening is configured for accommodating an LED light source therein.
