The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 2, a housing 10 according to a first embodiment of the present invention is shown, wherein a plurality of pen section accommodating cavities 11 are disposed thereon, the plurality of pen section accommodating cavities 11 form at least one "8" shaped structure, a light-shielding retaining wall 12 is disposed in the pen section accommodating cavity 11, the light-shielding retaining wall 12 is disposed at a central position of the pen section accommodating cavity 11, and the light-shielding retaining wall 12 is connected between two side walls of the pen section accommodating cavity 11 in a width direction, that is, the light-shielding retaining wall 12 is disposed along the width direction of the pen section accommodating cavity 11, and the light-shielding retaining wall 12 extends from the bottom of the pen section accommodating cavity 11 toward a light-emitting window 111 of the pen section accommodating cavity 11, that is, the bottom of the light-shielding retaining wall 12 is flush and coplanar with the bottom of the pen section accommodating cavity 11, and the light-shielding retaining wall 12 divides the pen section accommodating cavity 11 into two mounting regions 112.

It can be understood that when the height of the light-shielding walls 12 is not enough, the light-emitting height is increased to a limited extent, and a ghost phenomenon still exists (as shown in fig. 3), and when the height of the light-shielding walls 12 is too high, the light-emitting height is increased too much, which may cause the light not to cover the whole light-emitting window 111 (i.e. the light-emitting surface is too small), and may finally cause the uneven brightness of the pen segment with bright middle and dark edge (as shown in fig. 4), therefore, the best embodiment of the present invention is, as shown in fig. 5, the light-emitting height (H) of the led light source 20 near one side of the light-shielding walls 12 (H, the best embodiment of the present invention) isb/Ha) The height of the side wall of the same side with the pen section accommodating cavity 11 is equal, namely the right light emitting height (H) of the left led light sourceb) The height of the side wall on the right side of the pen section cavity 11 is equal to the height of the left light emitting height (H) of the right led light sourcea) The height of the light-emitting window is equal to that of the side wall of the left side of the pen section accommodating cavity 11, so that the double image phenomenon can be solved, the light can cover the whole light-emitting window 111, the brightness is ensured to be uniform, and the optimal light-emitting effect is achieved.
