The invention has the beneficial effects as follows:
(1) the present invention combines traditional area source with optical propagation and forming light guide plate technology, designed the arc LED area source that a kind of shape is changeable, make LED area source there is changeable, the luminous uniform effect of shape, make area source not only there is illumination, also there is sight, be applicable to more occasion, limitation breaks traditions.
(2) according to bending inner arc radius R >=5t (t is material thickness) when bending inner arc radius is more than or equal to 5 times of material thickness size, material bending part relative thickness changes little, can ignore the varied in thickness impact that conduction produces on light that bending produces.Therefore LGP bending R angle need be greater than 5 times of light guide plate, to such an extent as to be unlikely to destroy light guiding points structure during LGP bending and molding, realize better light transmition effect.
(3) according to the propagation characteristic of light, at LGP arc fold bending, place has carried out particular design to light guiding points, and the light guiding points at LGP arc fold bending place is arranged sparse compared with the light guiding points at LGP plane place, can better realize the reflection of bending place light; Thereby the little and thin opposite side that makes luminous energy more be transferred to bending of net-pont design, what light damaged at bending part like this is less, Integral luminous is even, the transmission of light is mainly to use the optical principles such as total reflection, refraction, according to the size and dimension of LGP, through accurate net-pont design, make it luminous even.
(4) side that at LGP light guiding points is set has been installed reflector plate, and the structure of reflector plate designs according to the bending structure of LGP, plays the effect of light reflection, can realize better reflecting effect.
(5) the LED lamp bar of LGP is arranged on the end of LGP arc-shaped bend structure, each LGP has the end of two curved bend folded structures, LED lamp bar can select to be arranged on the end of a curved bend folded structure and the end of two curved bend folded structures as required, and flexible structure also can obtain better illumination effect.
