Abstract:
1. A direct type backlight module structure, comprising: a light casing having a first height, wherein the light casing comprises a base plate; a reflection device disposed on the base plate, wherein the reflection device comprises a plurality of curved structural units, wherein each of the curved structural units is bent to form a second height and a middle base, and each of the curved structural units is configured at a predetermined spacing therebetween to be disposed on the base plate; and a plurality of light sources disposed on the reflection device, wherein each of the light sources is configured at the predetermined spacing, and the predetermined spacing is larger than the first height of the light casing; wherein each of the light sources is disposed on the intermediate base of each of the curved structural units of the reflection device to allow an emitted light of each of the light sources to pass through a surface of each of the curved structural units to form uniformly distributed reflection light; wherein each of the curved structural units comprises a mean curvature, by adjusting the second height and the mean curvature of each of the curved structural units to allow the light emitted from each of the light sources to pass through the surface of each of the curved structural units for forming uniformly the distributed reflection light.
