LIGHT-GUIDING MODULE AND LED LIGHT SOURCE USING THE SAME
First Claim
1. A light-guiding module for being fixed on an LED module to guide light emitted by a plurality of LEDs of the LED module, comprising:
- a frame for being placed on the LED module, defining an opening in a bottom portion thereof for receiving the LEDs of the LED module and a recess in an upper portion thereof and in communication with the opening, the recess having two undercuts at two sides of a bottom portion of the recess so that the recess has a dovetailed profile; and
a plurality of light guiding units each comprising 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 undercuts 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.

Abstract
An LED light source includes an LED module and a light-guiding module fixed on the LED module. The LED module includes a printed circuit board and a plurality of LEDs. The light-guiding module includes a frame placed on the LED module and a plurality of light guiding units engaging with the frame. The frame defines 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. Each of the light guiding units has a base with two flanges respectively fittingly received in two cutouts of the recess of the frame so that the light guiding unit is movable along the recess until it faces a corresponding LED.

10. 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. - View Dependent Claims (11, 12, 13, 14)
