| description | The present disclosure provides a light guide device including light sources and a light guide plate. A bottom end of the light guide plate faces the light sources and is provided with a light uniformization structure. The light uniformization structure is fixedly connected to the light guide plate. The light guide plate includes a main body, a first inclined portion, and a second inclined portion. The first inclined portion and the second inclined portion are respectively located on left and right sides of the main body. The first inclined portion and the second inclined portion are both fixedly connected to the main body, and top sides of the first inclined portion and the second inclined portion are both higher than a top side of the main body. The light uniformization structure includes a first light uniformization portion, a second light uniformization portion, and a third light uniformization portion. The first light uniformization portion and the third light uniformization portion are respectively located on left and right sides of the second light uniformization portion. The first light uniformization portion and the third light uniformization portion are both fixedly connected to the second light uniformization portion. The first light uniformization portion is configured for diverging light from the light sources to the first inclined portion, the third light uniformization portion is configured for diverging light from the light sources to the second inclined portion, and the second light uniformization portion is configured for diverging light from the light sources to the main body. The light guide plate can be uniformly illuminated through the present disclosure. |
