Fig. 1-2 schematically shows the photo-patterning device 100 according to an embodiment of the present utility model.This light pattern
Gasifying device 100 includes luminous intensity distribution unit 10 and reflector element 20.Luminous intensity distribution unit 10 has incident end face 11, outgoing end face 12 and side table
Face 13.This incident end face 11 and outgoing end face 12 lay respectively at the two ends of luminous intensity distribution unit 10, and described luminous intensity distribution unit 10 is additionally provided with
One or more side direction light portion 14.Described side direction light portion 14 may be located between incident end face 11 and outgoing end face 12
Position.Described side direction light portion 14 is arranged to guide from the Part I light 31 of incident end face 11 incidence from luminous intensity distribution unit 10
Side surface 13 penetrates, from the Part II light 32 of incident end face 11 incidence from described outgoing end face 12 towards photo-patterning device
The light exit side 40 of 100 penetrates.Described reflector element 20 is arranged to reception side surface 13 outgoing from described luminous intensity distribution unit 10
It is also reflected by light towards the light exit side 40 of photo-patterning device 100.As example, multiple side direction light portion 14 is being set
In the case of, multiple side direction light portions 14 can arrange successively along the direction from incident end face 11 to outgoing end face 12.The most every
