Abstract: The invention provides a liquid crystal alignment film, a method for preparing the same and a liquid crystal display device comprising the same. The alignment film comprises polyimide obtained by reacting the compound as shown in Formula 2 or Formula 3 with the aromatic diamine as shown in Formula 1, wherein the R1, R2, R3, R4, R5, R6, R7, R1?, R2?, R3?, R4?, R5?, R6?, R7?, or R8? substituent is H, alkyl, aralkyl or haloalkyl, and the Ar is aryl. The liquid crystal alignment film has a tactic spatial configuration, decreases the ?-? attractive interaction between the polyimide backbones, allows the directional and homogenous alignment of the liquid crystal molecules on the surface of the polyimide, and thereby increases the contrast of the liquid crystal display.

Abstract: A LED directional illumination energy-saving luminaire and a manufacturing method thereof. The luminaire comprises: a circuit board with an X direction and a Y direction defined; and illumination units including a first illumination unit arranged at the center of the circuit board, and two second illumination units arranged at both sides of the first illumination unit. Each illumination unit includes LEDs mounted to said circuit board in a tilted state with said LED bodies positioned at a predetermined height from the circuit board, and said LEDs are arranged at intervals in an array along said X direction and Y direction and distributed with respect to the center of said array. Each LED deviates from both X and Y directions at a predeterminative angle, so that the illumination units can form predeterminative project angles in the X direction and the Y direction respectively.
