Light-guiding module and led light source using the same

An LED light source comprising:

• an LED module comprising a printed circuit board and a plurality of LEDs mounted on the printed circuit board;
• a light-guiding module fixed on the LED module to guide light emitted by the LEDs of the LED module, comprising:
• a frame placed on the LED module and defining an opening in a lower portion thereof to receive the LEDs of the LED module therein and a recess in an upper portion thereof and in communication with the opening, the recess having two runners at two sides thereof;
• and
• a plurality of light guiding units each having a base having two flanges extending outwardly and laterally from two opposite lateral sides thereof;
• wherein the flanges of the base of each of the light guiding units are respectively received in the runners of the frame and movable along the recess to adjust a position of each of the light guiding units in the frame until each of the light guiding units faces a corresponding LED for reflecting and guiding light generated by the corresponding LED in a predetermined manner.
