| 发明名称 | Direct-type LED backlight module | ||
| 摘要 | A direct-type LED backlight module includes a supporting base having a supporting face, an LED mounted on the supporting face of the supporting base, and a dome-like light guiding cover positioned on the supporting face of the supporting base and covering the LED. The light guiding cover defines a plurality of through holes for permitting light emitted from the LED to pass through light guiding cover. The through holes are spaced from each other and arranged in a number of imaginary concentric circles relative to a center of the light guiding cover. An inner face of the light guiding cover facing the LED is coated with a reflective film. A semispherical light reflecting portion protrudes downwardly from an inner face of a top portion of the light guiding cover towards the LED. | ||
