[0032] The first base wall 11 has a first lower side surface 111 connected to the first side wall 12 , and a first upper side surface 112 opposite to the first lower side surface 111 .

[0033] Each of the first side walls 12 has a first inner side surface 121 connected to the first lower side surface 111 , and a first outer side surface 122 opposite to the first inner side surface 121 and connected to the first upper side surface 112 .

[0034] Two of the first side walls 12 are respectively formed with two embedding grooves 13. Each embedding groove 13 is formed on the corresponding first outer side surface 122 and the first upper side surface 112.

[0035] The light shielding layer 2 is black spray paint, and the light shielding layer 2 defines a character light transmission area 21 adjacent to the first upper side surface 112 of the first base wall 11. In this embodiment, the character light transmission area 21 presents a character pattern of the letter "A".

[0036] The color of the second cap 3 is similar to that of the first cap 1. The second cap 3 is also black. The light transmittance of the second cap 3 is lower than that of the first cap 1. The light transmittance of the second cap 3 is between 10% and 15%. The second cap 3 is disposed on the first cap 1 and is located above the first cap 1 and the character light transmission area 21. In other words, the character light transmission area 21 is located between the first cap 1 and the second cap 3.

[0037] The second cap 3 includes a second base wall 31 located above the first base wall 11 , four second side walls 32 extending downward from the second base wall 31 and connected to each other, and four protrusions 33 .

[0038] The second base wall 31 has a second lower side surface 311 connected to the second side wall 32 , and a second upper side surface 312 opposite to the second lower side surface 311 .

[0039] Each of the second side walls 32 has a second inner side surface 321 connected to the second lower side surface 311 , and a second outer side surface 322 opposite to the second inner side surface 321 and connected to the second upper side surface 312 .
