Abstract

The invention provides a modularized LED illuminator, wherein each module includes a power block and an illuminating block. The power block treats the extra power with rectification and transformation so that a working voltage is generated to the illuminating block for illuminating. Multiple modularized LED illuminators are connected in series or parallel to obtain larger brightness and modular connection.
