Abstract
An LED illuminator has a seat and multiple LED modules mounted on the seat. The seat has multiple chambers, each of which has two opposite sidewalls, a bottom, two through holes and an opening. The two through holes are respectively defined on the sidewalls and the opening is defined the bottom. The LED modules are respectively mounted on the sidewalls of the chambers on the seat and standing on the seat at an inclined angle to allow lights pass through the openings of the chambers. Therefore, each chamber has two light sources from two opposite sidewalls and the lights of the two lights source pass through the opening of the chamber. The LED illuminator provides a wide illuminating angle.
