Light emitting diode light source structure

The invention provides a light emitting diode light source structure, which comprises a light guide plate, a reflection cover and a plurality of light emitting diodes. The reflection cover is provided with a reflection structure and covers one side edge of the light guide plate. A gap is left between the reflection cover and the side edge and the reflection structure is opposite to the side edge of the light guide plate. The light emitting diodes are arranged in the gap between the light guide plate and the reflection cover and the light emitting sides thereof face the reflection structure which reflects the light from the light emitting diodes into the light guide plate. When the light emitting diode light source structure of the invention is adopted, the light shape of the light emitting sides is broken up by the reflection structure and then evenly reflected into the light guide plate to eliminate the uneven development phenomenon of a back light module.
