Abstract

A replaceable LED light source device used in a backlight module comprises a LED bar disposed with a plurality of LEDs thereon used for providing illumination and an attaching plate used for disposing the detachable LED bar within a case locating the backlight module therein. Thereby, the previous LED light source device can be replaced by a new one when any LED on the LED bar stops working.

Claims

1. A replaceable LED light source device used in a backlight module, comprising:

a detachable LED bar having a plurality of LEDs thereon for providing illumination of the backlight module;

an attaching plate for disposing the detachable LED bar within a case locating the backlight module therein via an aperture on the case.

2. The replaceable LED light source device used in a backlight module as claimed in claim 1, wherein the attaching plate is connected with the detachable LED bar via a first attaching part and with the case via a second attaching part, so that when any LED on the LED bar of a LED light source device stops working, a new LED light source device can replace the previous one by removing the second attaching part.

3. The replaceable LED light source device used in a backlight module as claimed in claim 2, wherein the attaching part can be a screw, sticky tape, or a double-side adhesive tape.

4. The replaceable LED light source device used in a backlight module as claimed in claim 1, wherein the aperture is provided on the lateral side of the case.

5. The replaceable LED light source device used in a backlight module as claimed in claim 1, wherein the aperture is provided on the bottom of the case.

6. The replaceable LED light source device used in a backlight module as claimed in claim 1, wherein the case is made by metal.

7. The replaceable LED light source device used in a backlight module as claimed in claim 6, wherein the metal for forming the case is copper or aluminum.

8. The replaceable LED light source device used in a backlight module as claimed in claim 6, wherein the attaching plate is made by metal and the attaching part is made by thermal-conductive material, so that the heat generated from the LED can be conducted to the case and dissipated therefrom.

9. The replaceable LED light source device used in a backlight module as claimed in claim 8, wherein the metal for forming the attaching plate is copper or aluminum.

10. The replaceable LED light source device used in a backlight module as claimed in claim 8, wherein the thermal-conductive material for forming the attaching part is selected from the group of a thermal-conductive adhesive tape, a thermal-conductive double-side adhesive tape, and an adhesive thermal pad.
