Abstract: A light guide plate having micro-reflectors is applied to a back light module of a liquid crystal display. A light source is disposed on one side of the light guide plate. Each of the micro-reflectors is shaped like a pyramid protruding from the bottom of the light guide plate and comprises a transparent plane and two reflection planes. The transparent plane is disposed at right angle to the bottom of the light guide plate, facing and comparatively nearer to the light source. Both the reflection planes are inclined to the bottom of the light guide plate, facing the illuminating surface of the light guide plate and comparatively farther from the light source to reflect rays of light upward to increase luminance of the light guide plate, and thereby changing arrangement of the micro-reflectors to improve consistent luminance of the light guide plate.

Abstract: The present invention is related to a light-guiding element, a light-emitting diode (LED) lamp tube and an illumination lamp. The present invention utilizes a light-guiding element disposed on a light-emitting unit of the LED lamp tube. The light-guiding element includes a first surface and a second surface. The first surface is spaced with a plurality of reflecting units in a longitudinal direction thereof, and the second surface is partitioned with a reflecting area and non-reflecting areas corresponding to the reflecting units of the first surface. The light-emitting unit includes LEDs correspondingly attached to the non-reflecting areas of the second surface of the light-guiding element.
