Preferably, enter light slitter line 113 with enter light traverse 112 ratio be more than light extraction slitter line 123 and light extraction it is crosscutting
The ratio of line 122.So that incidence surface 11 is longer and narrower compared with light-emitting surface 12.
Enter light traverse 112 and light extraction traverse 123 is mutually parallel.It is worth noting that, being mutually parallel here, not
The decision being limited on data sense is parallel, can also include approximately parallel scope, this will not be repeated here.Also, enter light to indulge
Default line-spacing threshold value is smaller than between tangent line 113 and light extraction slitter line 123, this default line-spacing threshold value can be set in advance
It is fixed, such as can be 1 millimeter or other values.In actual use, the very little that preset can be set away from threshold value so that enter light
Slitter line 113 and light extraction slitter line 123 are essentially coincided or are completely superposed.
Incidence surface 11 and light-emitting surface 12 are respectively provided with central point, which is the centre position or extreme higher position of face type.
By taking incidence surface 11 and light-emitting surface 12 are four-quadrant symmetricals as an example, then the projection of the central point in the two faces in the horizontal plane is
Enter light slitter line 113 and enter the intersection point of light traverse 112 and the intersection point of light extraction slitter line 123 and light extraction traverse 122.In this reality
It applies in example, incidence surface 11 and light-emitting surface 12 are respectively provided with central point and stagger in vertical direction, i.e. the line of the two is not vertical
Direction.
In the utility model embodiment, along the traverse of the light-emitting surface, thickness has between incidence surface and light-emitting surface
Following relation：12 central point of light-emitting surface and the thickness of incidence surface 11 are minimum, in 12 central point both sides of light-emitting surface and incidence surface 11
In increase trend and symmetrically, i.e. 12 central point of light-emitting surface is separation to thickness, and the thickness of both sides is incrementally and increasing degree phase
Together.
Fig. 7 is sectional view of the light source module group 100 of part shown in Fig. 4 on B-B directions.Plane where B-B directions can
To be interpreted as the vertical plane vertical with A-A directions, light distribution element 10 is still disposed on horizontal plane at this time.Below in conjunction with Fig. 4 institutes

Member 20 is located on the light extraction slitter line 123 of light-emitting surface 12 and the intersection point of light extraction traverse 122.
It is worth noting that：In the utility model embodiment, " central point of luminescence unit 20 and light-emitting surface 12 is vertical
Align on direction " it is not absolute alignment in mathematical meaning, luminescence unit 20 can also generate one with the central point of light-emitting surface 12
Fixed offset, the scope of this offset can be：Offset distance between the central point of the center of the luminescence unit and the light-emitting surface
From the 20% of luminescence unit width, offset here can be any direction.For example, it may be deviate 0.55mm toward one side
In the range of.
If light distribution element 10 only covers a luminescence unit 20, it is only necessary to determine the size of the luminescence unit 20, if with
It is to move luminescence unit 20 along traverse direction, then using the size of luminescence unit 20 on traverse direction as its width.
If light distribution element 10 covers multiple luminescence units 20, then the overall dimensions of these luminescence units 20 are obtained, are not done herein
It repeats.
