Disclosed is a LCD back light module structure comprising one or more than one LED arrayed along an electric conducting stick which being equipped with conductor blades on its surface. The conductor blade is used for connecting the conducting stick to a driving circuit. A blind hole is formed on the conducting stick and the light spot of the Led die is buried in the blind hold and the electric connection is extended from the light spot to the adjacent two conductor blades. After being completed connection for each LED die, the epoxy resin is infused around the blind hole to form a transparent lens. The high crowned configuration of the lens enables the LED to uniformly emit the light therefrom therefore each LED forms a uniformly brilliant lighting surface on the LCD back light module structure.
