145 can determine according to the light-emitting component spacing 151 between corresponding light-emitting component 125 and light-emitting surface 121.If using scattering
The subtended angle 145 of element 143, then light cone 136 limited by partition wall 131, corresponding can be according to corresponding light-emitting component 125
Spacing 152 determines on the inside of dispersing element between the dispersing element inside 144 of dispersing element 143.
If corresponding light-emitting component 125 is for example farther apart on the inside of light-emitting surface 121 or dispersing element 144, shine
Spacing 152 increases on the inside of element spacing 151 or dispersing element, and the subtended angle 145 of corresponding light cone 136 and corresponding cone basal plane
139 become smaller.
Corresponding light-emitting component is especially less than by the subtended angle 145 of light cone 136 limited by partition wall 131, corresponding
125 angle of emergence 153, it is ensured that light cone 136 is effectively limited by partition wall 131.
The shape of corresponding light cone 136, particularly the subtended angle 145 of corresponding light cone 136 and/or corresponding light cone as a result,
136 cone basal plane 139 can by changing spacing 152 on the inside of light-emitting component spacing 151 or dispersing element, it is lateral by changing
Partition wall spacing 149 is changed accordingly by changing the corresponding first or second partition wall spacing 147-1,147-2 and/or passing through
Partition wall length 148 and change, so as to the thus advantageously respective corresponding overlapping region between adjacent light cone 136 of setting
135。
