Abstract
Disclosed herein is a light source device using light-emitting diodes (LEDs). Specifically, a two-sided, surface light source device is implemented with point light sources such as LEDs in a simple configuration, such that even surface light is emitted. The two-sided, surface light source device includes: a substrate on which light-emitting diodes (LEDs) are disposed as a light source; and a two-sided diffusion unit having a plate-like shape with a front side face, a back side face, and a light-receiving face that is perpendicular to the front side face and the back side face and faces the substrate. Light emitted from the light source is diffused in the diffusion unit and exits through the front side face and the back side face.
Claims20
A two-sided, surface light source device, comprising:
- a substrate;
- light-emitting diodes (LEDs) disposed on the substrate and operable as a light source;
- and
- a two-sided diffusion unit having a front face, a back face, and a light-receiving face that is perpendicular to the front face and the back face, the light-receiving face facing the substrate, wherein light emitted from the light source is diffused in the two-sided diffusion unit and exits through the front face and the back face.
A two-sided, surface light source device using LEDs, the device comprising:
- a first substrate on which LEDs are disposed to operate as a light source;
- a second substrate on which LEDs are disposed to operate as a light source;
- and
- a two-sided diffusion unit having a first light-receiving face facing the first substrate and a second light-receiving face facing the second substrate, wherein lights emitted from the light sources are diffused in the two-sided diffusion unit and exit through a first face and a second face that are perpendicular to the first light-receiving face and the second light-receiving face.
