Abstract:
The present invention disclosed a flat lamp, comprising a light guide layer, a reflective laver, a diffusion layer, a buffer layer, and a backplane, the light guide layer has two opposite faces including a back face and a light emitting face, the reflective layer is located on the back face of the light guide layer, the diffusion layer is located on the light emitting face of the light guide layer, the buffer layer is located between the backplane and the reflective layer, and several light guide points are provided between the reflective layer and the light guide layer, the flat lamp further comprises a light source and an outer frame, with incident points being located on a lateral side of the light guide layer, the stacked structure is in the shape of a flat plate.

Claim (Index 3):
The flat lamp according to  claim 1 , wherein the stacked structure composed of the backplane, the light guide layer, the reflection layer, the buffer layer and the diffusion layer is in the shape of a flat plate structure which is one of the following three:\n (1) the light guide layer, the buffer layer, the reflective layer and the backplane are all in the shape of a flat plate (2) the light guide layer is a wedge-shaped light guide layer with a right-angled trapezoidal cross-section, the buffer layer is a wedge-shaped buffer layer with a right-angled trapezoidal cross-section, and the back face of the light guide layer is a first inclined plane, the side of the buffer layer close to the reflection layer is a second inclined plane, the first inclined plane is parallel to the second inclined plane, the reflection layer is positioned between the first inclined plane and the second inclined plane, and the backplane and the reflection layer are in the shape of a flat plate. (3) the light guide layer is a wedge-shaped light guide layer with a right-angled trapezoidal cross-section, the backplane is a wedge-shaped layer with a right-angled trapezoidal cross-section, and the back face of the light guide layer is a first inclined plane, the inner face of the backplane is a second inclined plane, the first inclined plane is parallel to the second inclined plane, and the backplane and the reflection layer are both in the shape of a flat plate.
