More Information
Summary:Disclosed is a thin LED lens including a lens body being an inverted frusto-conical shaped structure, a light exit surface formed on a non-frustum end of the lens body, and an accommodating chamber formed at a frustum end of the lens body, characterized in that the accommodating chamber has a primary accommodating chamber and at least one secondary accommodating chamber disposed around the primary accommodating chamber, such that the primary accommodating chamber and the secondary accommodating chamber are arranged in a concentric and radial shape, and the secondary accommodating chamber is in form of a circular groove. The thin LED lens can be made thinner to achieve the effects of facilitating the manufacture, reducing the material, and providing a better light distribution.
