113 are arranged far from light in part 12, and the second guide-lighting line rarefaction 113 and the second guide-lighting line compact district 114 are disposed adjacent.Specifically
Ground, guide-lighting line are the groove opened up on 10 surface of raised item or light guide for be arranged in 10 surface of light guide, and the second guide-lighting line is dilute
It dredges in area 113 and the second guide-lighting line compact district 114 and is provided with a plurality of adjacent guide-lighting line.Wherein, the second guide-lighting line rarefaction
Spacing in 113 between adjacent guide-lighting line is greater than the spacing between guide-lighting line adjacent in the second guide-lighting line compact district 114, i.e.,
Density of the density of guide-lighting line less than guide-lighting line in the second guide-lighting line compact district 114 in second guide-lighting line rarefaction 113.
In the present embodiment, the second guide-lighting line rarefaction 113 and 114 quantity of the second guide-lighting line compact district are two, two
Second guide-lighting line compact district 114 is separately positioned at two light in part 12, and two second guide-lighting line rarefactions 113 are separately positioned on
Between two second guide-lighting line compact districts 114, it is arranged far from light in part 12.Second guide-lighting line compact district 114 is close to light in part 12
Setting, close to illuminating source, light source is sufficient, and light is after light in part 12 enters light guide ring 11, in the second guide-lighting line compact district 114
The guide-lighting line of intensive bumps makes light form multiple reflections enhancing incident side brightness, reduces the brightness of light emission side；Second guide-lighting line
Rarefaction 113 is arranged far from light in part 12, and it is dilute that light enters the second guide-lighting line after 114 multiple reflections of the second guide-lighting line compact district
Area 113 is dredged, the guide-lighting line spacing in the second guide-lighting line rarefaction 113 is larger to form diffusing reflection to light, weakens incident side light
Brightness, to enhance light emission side light luminance.In the present embodiment, close to the area of light in part 12 on 11 light emission side surface of light guide ring
The second guide-lighting line of domain setting compact district 114 carries out the light luminance of multiple reflections enhancing incident side to incident ray to weaken leaded light
Brightness of the ring 11 close to source region light emission side.Also, the region on 11 light emission side surface of light guide ring far from light in part 12 is set
The light luminance that separate source region incident side in light guide ring 11 is weakened in the second guide-lighting line rarefaction 113 is set, light guide ring 11 is enhanced
Brightness far from source region light emission side makes the whole uniform in light emission of light guide ring 11, further increases the maintaining uniform illumination of light guide 10
Property.
In the present embodiment, the quantity of the second guide-lighting line rarefaction 113 and the second guide-lighting line compact district 114 is two.It is real
In the application of border, the quantity of the second guide-lighting line rarefaction 113 and the second guide-lighting line compact district 114 is carried out according to the quantity of light in part 12
Setting, the second guide-lighting line rarefaction 113 and the second guide-lighting line compact district 114 are identical as the quantity of light in part 12, as long as guaranteeing
Second guide-lighting line compact district 114 is arranged close to light in part 12, and the second guide-lighting line rarefaction 113 is arranged far from light in part 12.
In addition, as shown in fig. 6, the area of the second guide-lighting line compact district 114 is greater than the second guide-lighting line rarefaction 113 in the present embodiment
Still in practical application, it is guide-lighting that the second guide-lighting line rarefaction 113 and second can be arbitrarily arranged in area according to specific application environment
The area of line compact district 114, the present embodiment are simultaneously not specifically limited.
In another embodiment, the incident side surface of light guide ring 11 has been disposed adjacent a plurality of guide-lighting line, by light guide ring 11
With the region of light in part 12 separate on light in part 12 junction to light guide ring 11, the distance between adjacent guide-lighting line gradually becomes
Greatly.Specifically, in the present embodiment, a plurality of guide-lighting line of setting on the incident side surface of guide-lighting line 11, also, by light guide ring 11 with enter
Far from the region of light in part 12 on light portion 12 junction to light guide ring 11, guide-lighting line is gradually by being intensively thinned out.Light guide ring 11 with
The junction leaded light line of light in part 12 is most intensive, and light guide ring 11 and the density of the junction leaded light line of each light in part 12 are equal
Identical, from each light in part 12 to the region far from the light in part 12, from the remoter region of light in part 12 is corresponded to, guide-lighting line is diluter
It dredges, the midpoint leaded light line between two adjacent light in part 12 is most sparse.Light guide ring 11 and 12 junction of light in part are close to hair
Radiant, light source is sufficient, and intensive guide-lighting line carries out multiple reflections to incident ray, enhances incident side brightness, leads to reduce
The brightness of 11 light incidence section domain light emission side of the ring of light；Light injects the region in light guide ring 11 far from light in part 12 after multiple reflections,
For incident side leaded light line by being intensively thinned out, sparse guide-lighting line carries out diffusing reflection to light, reduces incident side light luminance, enhancing
Far from the brightness of source region light emission side in light guide ring 11, so that it is guaranteed that the whole uniform in light emission of light guide ring 11, improves light guide 10
Illumination uniformity.
Further, in one embodiment, the light emission side surface of light guide ring 11 is provided with the first guide-lighting line rarefaction 111
With the first guide-lighting line compact district 112, the first guide-lighting line rarefaction 111 is arranged close to light in part 12, the first guide-lighting line compact district 112
It is arranged far from light in part, and the first guide-lighting line rarefaction 111 and the first guide-lighting line compact district 112 are disposed adjacent；Light guide ring 11
Incident side surface is provided with the second guide-lighting line rarefaction 113 and the second guide-lighting line compact district 114, the second guide-lighting line compact district 114
Nearly light in part setting, the second guide-lighting line rarefaction 113 are arranged far from light in part, and the second guide-lighting line rarefaction 113 and second is led
Light line compact district 114 is disposed adjacent.
Specifically, light guide ring 11 is close to the region of light in part 12 close to illuminating source, and light source is sufficient, in entering for light guide ring 11
The second guide-lighting line of light side surface setting compact district 114, the first guide-lighting line of light emission side surface setting rarefaction 111, light, which enters, leads
Body of light 11 is irradiated to the second guide-lighting line compact district 114 and is all reflected back in light guide 10 by multiple transmitting, enhances incident side brightness,
Reduce light emission side brightness；Also, when light is irradiated to the first guide-lighting line rarefaction 111, sparse guide-lighting line overflows light
Reflection weakens light luminance, and the first guide-lighting line rarefaction 111 and the second guide-lighting line compact district 114 act on simultaneously, reduces light guide ring
11 close to 12 region of light in part brightness.Further, guide-lighting far from the weaker region of 12 light of light in part in light guide ring 11
The second guide-lighting line of incident side surface setting rarefaction 113 of ring 11, the first guide-lighting line of light emission side surface setting compact district 112, light
When line is irradiated to the second guide-lighting line rarefaction 113, the sparse guide-lighting line on the second guide-lighting line rarefaction 113 forms light unrestrained
Reflection reduces incident side brightness, enhances light emission side brightness；Meanwhile light is when being irradiated to the first guide-lighting line compact district 112, first
