Abstract
A reflection-diffusion structure adopted for a light guide plate has a left wall, a right wall, and a bottom wall, which all are made of reflection materials. A top wall connects to the bottom wall, the left wall and the right wall, and a receiving cavity is formed by the left wall, the right wall, the top wall and the bottom wall. The top wall has a size-adjustable diffusion area made of a diffusion material. The left wall, the right wall, the top wall and the bottom wall are made integrally in one piece. The reflection material and the diffusion material are made integrally in one piece.

A reflection-diffusion structure adopted for a light guide plate, comprising:
- a foldable single piece member having first, second, third and fourth portions thereof, each said portion having a pair of opposing first and second sides and a pair of opposing first and second edges, said second portion being integrally connected by the first side thereof to the second side of said first portion, said third portion being integrally connected by the first side thereof to the second side of said second portion, and said fourth portion being integrally connected by the first side thereof to the second side of said third portion,
- said foldable single piece member being folded along said opposing first and second sides with the first side of said first portion connected to the second side of said fourth portion to form a box-like structure, wherein
- a left wall of said box-like structure coincides with said fourth portion, said left wall being made of a first reflection material,
- a right wall of said box-like structure coincides with said second portion, said right wall being made of a second reflection material,
- a bottom wall of said box-like structure coincides with said first portion and connects the left wall and the right wall, said bottom wall being made of a third reflection material, and
- a top wall of said box-like structure coincides with said third portion and connects the left wall and the right wall, the top wall including a size-adjustable diffusion area made of a diffusion material;
- a receiving cavity being formed in said box-like structure by the left wall, the right wall, the top wall and the bottom wall for receiving the light guide plate and a light therewithin;
- and
- wherein the left wall, the right wall, the top wall and the bottom wall are connected integrally in a single piece, and wherein the first reflection material, the second reflection material, the third reflection material and the diffusion material are connected integrally in a single piece.
