Abstract
A LED light source module includes a printed circuit board and a plurality of LEDs. The printed circuit board has a plurality of through holes arranged in intervals. Each of the LEDs includes at least one LED chip and at least one metal board. The metal board has a supporting surface. The LED chip is arranged on the supporting surface. At least one of the LED chip and the metal board is contained in each through hole of the printed circuit board corresponding to the LED including the at least one of the LED chip and the metal board. Each of the LEDs electrically is connected with printed circuit board through the supporting surface of the metal board to make the LED chip be connected with the printed circuit board electrically.
Claims16
A light source module, comprising:
- a printed circuit board, having a plurality of through holes arranged in intervals;
- and
- a plurality of light emitting diodes packaged independent of the printed circuit board, each of the packaged light emitting diodes including at least one chip, at least one metal board and a package, the metal board having a supporting surface, the chip being arranged on the supporting surface, the package being arranged on the supporting surface to seal the chip therein, at least one of the chip and the metal board being contained in the through hole of the printed circuit board corresponding to the light emitting diode including the at least one of the chip and the metal board, and each of the light emitting diodes electrically being connected with the printed circuit board through the metal board and such that the chip is connected with the printed circuit board electrically by the supporting surface of the metal board.
A backlight module, comprising:
