Abstract

A light source for a flat panel display device is disclosed. The light source comprising: a lamp tube having a first connector at one end thereof and a second connector at the opposite end thereof; a first leading wire connecting with the first connector; a second leading wire connecting with the second connector; and an electric plug adapted for fixing the first leading wire and the second leading wire both extending from the second connector; wherein the length of the second leading wire between the second connector and the electric plug is longer than the length of the first leading wire between the second connector and the electric plug. Therefore, the major part of the applied stress on the wires can be substantially distributed through the first leading wire and the breakagE of the lamp tube at the area around the second connector can be effectively prevented.

Claims (11)

1. A light source for a flat panel display device comprising: a lamp tube having a first connector at one end thereof and a second connector at an opposite end thereof;

a first leading wire connecting with said first connector;

a second leading wire connecting with said second connector which has a connecting hole or a fixing frame to fix said first leading wire extending from said first connector; and

an electric plug adapted for fixing said first leading wire and said second leading wire both extending from said second connector, wherein

the length of said second leading wire between said second connector and said electric plug is longer than the length of said first leading wire between said second connector and said electric plug to distribute a major part of stress applied on said first leading wire and said second leading wire through said first leading wire.

2. The light source as claimed in claim 1 , wherein the length of said second leading wire between said second connector and said electric plug is at least 1 mm longer than the length of said first leading wire between said second connector and said electric plug.

3. The light source as claimed in claim 1 , wherein the length of said second leading wire between said second connector and said electric plug is at least 5 mm longer than the length of said first leading wire between said second connector and said electric plug.

4. The light source as claimed in claim 1 , wherein the flat panel display is a liquid crystal display device.

5. A backlight module for a flat panel display device comprising at least one said light source for a flat panel display as claimed in claim 1 .

6. The backlight module as claimed in claim 5 , wherein the length of said second leading wire between said second connector and said electric plug is at least 1 mm longer than the length of said first leading wire between said second connector and said electric plug.

7. The backlight module as claimed in claim 5 , wherein the length of said second leading wire between said second connector and said electric plug is at least 5 mm longer than the length of said first leading wire between said second connector and said electric plug.
