Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
It is as shown in Figures 1 and 2: present embodiment discloses a kind of novel bending light guide plate, including light guide plate and LED light strip 5,
Light guide plate includes the first light guide plate 1 and the second light guide plate 3, passes through transition circle arc angle between the first light guide plate 1 and the second light guide plate 3
2 connections, the first light guide plate 1 are equipped with groove perpendicular to the second light guide plate 3, the one side of the second light guide plate 3, and the upper edge on groove one side is set
There is protrusion 31, groove connects LED light strip 5, when LED light strip 5 is connected to groove, the side connection bump 31 of LED light strip 5, separately
Side is connected to the inner wall of groove by connection card 6, and the groove side of the first light guide plate 1 is additionally provided with reflective membrane 4, the hair of reflective membrane 4
Smooth surface connects the first light guide plate 1, and light guide plate is acrylic material.
As shown in Figure 3: connection card 6 includes arc section 61, elastic slice 62 and hand-held part 63, and there are two elastic slices 62, two elastic slices
62 one end is connected by arc section 61, and the other end connects hand-held part 63, and the side of elastic slice 62 is additionally provided with ratchet 621.
The ratchet 621 of two elastic slices 62 it is contrary, such purpose is can to make direction and the LED light of ratchet 621
It is skidded off with 5 from groove contrary.
Specifically, showing for end light leakage occurs in order to avoid the distance between LED light strip 5 and the first light guide plate 1 are too small
As,
The distance between groove and the first light guide plate 1 A are greater than the width of groove, and reflective membrane 4 is also attached to first and leads
The end of tabula rasa 1.Optimum distance between groove and the first light guide plate 1 is 7mm.
The depth of groove is not more than the half of the first light guide plate 1.This is in order to avoid the first light guide plate 1 is in groove intensity
It is too low, it is broken.
When installation, LED light strip 5 is put to the inside of groove first, when placement, should first be placed the side of LED light strip 5
To the inside of protrusion 31, the hand-held part 63 of connection card 6 is then pinched with hand, by connection card 6 be put into LED light strip 5 and groove it
Between, after placement, the ratchet 621 of two sides can be avoided LED light strip 5 and skid off from inside grooves.Then reflective membrane 4 is sticked,
4 one side of reflective membrane can further avoid LED light strip 5 and skid off from inside grooves, on the other hand can be avoided and light leakage occurs
Phenomenon.Due to only pasting reflective membrane 4 on the first light guide plate 1, light source can be under the action of reflective membrane 4 to the first light guide plate
1 groove contralateral reflex, the second light guide plate 3 paste reflective membrane due to farther out, not needing apart from light source.Transition circle arc angle 2
It can further avoid light guide plate and light leakage occurs.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
