Embodiment two
Referring to Fig. 9, the present embodiment is with the difference of embodiment one: on the led light-guiding pillar of the present invention, on the 4th end face
It is provided with a curved body 13 raising up, the curved surface of curved body 13 is the exiting surface of led light-guiding pillar, curved body 13 contributes to changing
Rare book invents the zoom performance of led light-guiding pillar.
In the present embodiment, curved body 13 and the second column 12 are formed in one.
Embodiment three
Referring to Fig. 7, Fig. 8 and Figure 10, the present embodiment is with the difference of embodiment one: on led light-guiding pillar, ring-type wave
The microgroove 12a of shape extends towards the 4th end face outside the 3rd end face is along second, the development length of ring-type corrugated microgroove 12a
For the length 2/3 to 3/4 of the second column 12, the remainder polishing of the second column 12, is smooth surface, the second post
The length of shape body 12 polishing part is the 1/4 to 1/3 of the second column 12 length.
On led light-guiding pillar, the partially polished process of the second column 12 upper end, it is because that radial structure can be in processing
Middle deformation, and during led light-guiding pillar cooperation zoom lens use, the process of zoom stroke is the equal of zoom lens
In the imaging of led light-guiding pillar differing heights position, this processing light that cause of flaw can be deformed into as out, and the second post
Imaging region can become smooth part by the mode of the partially polished process of shape body 12 upper end, this tooth would not
Shape flaw.
On led light-guiding pillar, the partially polished process of the second column 12 upper end, both defined the column of a strip
There is the led light-guiding pillar of ring-type corrugated microgroove 12a part and smooth surface portion.The column top local of strip is carried out
Polishing, can eliminate the radial problem of light spot edge causing due to mismachining tolerance；And remain remainder setting
The led light guiding lens of ring-type corrugated microgroove 12a, compared with embodiment one, remain that original length of lens is short, light mixing effect
Advantage that is good, being not required to interpolation abrasive segments, also eliminates the blood streak shape miscellaneous spot that led light guiding lens occur in zooming procedure simultaneously
Defect, improves uniformity of chromaticity and the aesthetic property of hot spot.
On led light-guiding pillar, the length of the second column 12 polishing part is the 1/4 to 1/ of the second column 12 length
3, because very few polishing can reduce uniformity degree, and excessive polishing can reduce overall uniformity.
