  The present invention relates to a light source module, and more particularly to a package structure of an LED light source module that can be directly attached and used as a lamp.

  A conventional LED module package structure includes a substrate on which an LED is mounted. The substrate is an aluminum substrate, a ceramic substrate, or a glass fiber substrate, and electrode contacts are provided on the plate surface. One or more light emitting diodes (LEDs) arranged on the board surface of the substrate are electrically connected to the electrode contacts, and then the light emitting diodes are sealed when the sealing material filled on the light emitting diodes is solidified and molded. A transparent structure is obtained. This transparent structure can generate a predetermined optical effect in the light source of the light emitting diode.

  However, when a conventional LED module is actually used as a lamp, it must supply a voltage and current corresponding to the LED. Therefore, the LED module is not directly connected. It was necessary to stabilize. However, in the conventional lamp, since components such as a driver IC and a resistor are arranged in the lamp and are not connected to the substrate of the LED module described above, the LED module formed by the sealing method described above directly conducts. The lamp cannot be formed by the method. Therefore, it has been difficult to use widely in downstream industries.

  Therefore, there has been a demand for an LED light source module that can be used directly as a lamp by directly conducting the LED light source module to emit light without disposing an electronic circuit in the lamp.

In addition, a LED light source module is provided that generates a predetermined optical effect in the light source of the LED.

  Moreover, it is preferable that a plurality of the LEDs are arranged on the circuit board.

  In addition, the circuit board has a recessed portion having a predetermined depth, and the sealing layer is filled with the sealing material after the driver IC and the LED are installed in the recessed portion, It is preferable that the sealing material has the transparent structure formed by solidification.

  Moreover, it is preferable to further include a resistor that is electrically connected to the output terminal of the driver IC and the LED and is covered with the transparent structure of the sealing layer.
