MODULE FOR LIGHT EMITTING DIODE

摘要

An LED module is provided to lengthen a lifetime of an LED by radiating smoothly heat through a metal case installed above an electrical circuit board. A case(100) includes outer walls(101-104) and a bottom surface having a groove(107) formed in one direction. The case is composed of a metal material. An electrical circuit board(200) includes a bottom surface which comes in contact with the bottom surface of the case except for the groove. A plurality of LEDs(203-206) are installed on an upper surface of the electrical circuit board. A resin layer is formed to seal the electrical circuit board except for light emitting sides of the LEDs. An area of the electrical circuit board is smaller than an area surrounded with the outer walls.
