LED MODULE

摘要

The purpose of the present invention is to reduce the size and thickness of an LED module in which a plurality of LED dies along with other electronic components are mounted on a circuit board, and at the same time to stabilize the operation of the module with respect to source voltage fluctuation. The LED module includes: a circuit board; a plurality of LED dies that are mounted on one surface of a circuit board as bare chips and constitute a series circuit; an FET die that is mounted on the one surface of a circuit board as bare chips and controls a current flowing through the plurality of LED dies; and a constant current circuit that is mounted on the one surface of a circuit board and is series-connected to the series circuit. The constant current circuit includes the FET die.
