Some extended configurations that the side corresponding with the metal frame is alignd；Or the reflector plate is except near the light emitting source one
Some binding structures for pasting on the corresponding side of the light guide plate are included on its excess-three end outside end and is being removed
Remaining two jiaos outside two jiaos of the light emitting source are each provided with the two jiao extended configurations alignd corresponding with the metal frame.
Further, the length of extended configuration of the reflector plate per one end is equal to the corresponding side of the light guide plate
To the distance of the corresponding side of the metal frame.
Further, the metal frame periphery is provided with coating frame.
Further, the metal frame and the coating frame are connected by buckle structure.
