Optical lens and backlight module incorporating the same |
| abstract |
An optical lens includes a first optical surface located at a bottom thereof, a third optical surface located at a top thereof and arranged oppositely to the first optical surface, and a second optical surface extending between the first optical surface and the third optical surface. The third optical surface is recessed downwardly towards the first optical surface. The light from the LED light source enters into the optical lens through the first optical surface, most of the entering light is directly refracted out of the optical lens through the second optical surface, and a part of the entering light that strikes the third optical surface is first reflected by the third optical surface towards the second optical surface via total internal reflection and then refracted out of the optical lens through the second optical surface. A backlight module incorporating the optical lens is also provided. |
