Abstract
A diffusion unit of a light-emitting module is disposed adjacent to at least one light source. The light source emits a light beam. The diffusion unit includes a first diffusion sheet and a second diffusion sheet. The thickness of the first diffusion sheet is less than 1 mm, and the thickness of the second diffusion sheet is also less than 1 mm. The second diffusion sheet is disposed adjacent to the first diffusion sheet. The light beam is directly emitted from the light source directly to the first diffusion sheet. A light-emitting module and a diffusion sheet are also disclosed.
Claims26
A diffusion unit of a light-emitting module disposed adjacent to at least one light source, which emits a light beam, the diffusion unit comprising:
- a first diffusion sheet having a thickness less than 1 mm;
- and
- a second diffusion sheet having a thickness less than 1 mm, wherein the second diffusion sheet is disposed adjacent to the first diffusion sheet, and the light beam is directly emitted from the light source to the first diffusion sheet.
A light-emitting module, comprising:
- at lease one light source emitting a light beam;
- a diffusion unit comprising a first diffusion sheet and a second diffusion sheet wherein the thicknesses of the first diffusion sheet and the second diffusion sheet are less than 1 mm, the second diffusion sheet is disposed adjacent to the first diffusion sheet, and the light beam is directly emitted from the light source to the first diffusion sheet;
- and
- a supporting unit supporting the diffusion unit.
A diffusion sheet, comprising:
- a substrate;
- and
- a diffusion material having at least one high-density area and at least one low-density area.
