The normal direction of cylindrical lens 7 and horizontal plane angle 8 ° ~ 12 °.
The face of cylinder in the middle part of Reflecting backboard 9 reflective surface is greater than the face of cylinder at two ends, left and right.
The face of cylinder at middle part is made up of a face of cylinder, and the face of cylinder at two ends, left and right is made up of multiple parallel face of cylinder array.
Optical collector 4 is coated with the taper cup of reflecting coating for inwall.
Optical fiber 5 is PMMA optical fiber, and diameter is 12mm.
Optical coupling structure 6 inner surface is reflecting surface.
Diffuse out optic panel 10 for acrylic board.
The utility model, relative to prior art, has following advantage and effect:
1) adopt natural daylight as lighting source, adopt the combinations such as optical collector, light-emitting plate and optical fiber, obtain the natural daylight containing various wavelength, solve the blue light of LED flat lamp existence to the harm problem of the health of people.
2) adopt natural daylight as light source, avoiding energy resource consumption, thus saved resource, is a kind of green light fixture.
3) adopt the flat lamp structure without light guide plate to make flat lamp structure more frivolous, and dramatically saves on production cost.
4) by the structure of side entering type, cylindrical lens is to the convergence effect of light and plunder the bright dipping mode of penetrating, in conjunction with the structure (middle part of reflective surface and two ends, left and right are provided with the protruding face of cylinder) of free form surface backlight, obtained the illuminating effect of uniform in light emission by the reflection of light.
5) the utility model technological means is easy, is skillfully constructed, not only cheap, energy-conserving and environment-protective, and is a kind of new light illumination mode being beneficial to health.
