Partially luminous fan blade and fan containing same
A partially luminous fan blade and fan containing same. The fan blade includes a light guide bracket, an annular sleeve, and a plurality of blades. The light guide bracket is formed with a shaft connection portion. The annular sleeve is integrated with the blades. The annular sleeve and the light guide bracket together form a hub portion of the fan blade. The annular sleeve is connected to the light guide bracket. The annular sleeve is provided with a light-shielding skirt. A bottom edge of the light-shielding skirt is lower than that of the light guide bracket.
1. A partially luminous fan blade, comprising:
a light guide bracket, formed with a shaft connection portion, the light guide bracket comprising a base portion, an annular portion integrated with the base portion, and an accommodating space defined by the base portion and the annular portion, the shaft connection portion integrally extended from the base portion and facing the accommodating space, and the light guide bracket comprising a plurality of ribs disposed at intervals on a side of the annular portion facing the accommodating space; and
an annular sleeve, integrated with a plurality of blades, wherein the annular sleeve is connected to the annular portion of the light guide bracket to together form a hub portion of the partially luminous fan blade, the annular sleeve is connected to the light guide bracket, the annular sleeve comprises a light-shielding skirt, and a bottom edge of the light-shielding skirt is lower than that of the light guide bracket.
2. The partially luminous fan blade according to claim 1 , wherein the annular sleeve comprises at least one cover portion contacting a lateral surface of the base portion not facing the accommodating space.
3. The partially luminous fan blade according to claim 1 , wherein the partially luminous fan blade comprises at least one light-shielding cover plate stacked on the light guide bracket.
4. The partially luminous fan blade according to claim 3 , wherein the base portion comprises an assembly area provided for assembling the at least one light-shielding cover plate.
5. The partially luminous fan blade according to claim 4 , wherein the light guide bracket comprises a light guide slant disposed at a junction between the base portion and the annular portion.
6. The partially luminous fan blade according to claim 5 , wherein an end of the annular portion opposite to the base portion comprises a light-incident slant.
7. The partially luminous fan blade according to claim 1 , wherein the light-shielding skirt comprises a slant protruding from a bottom edge of the light guide bracket.
8. A fan, comprising:
a fan frame;
a drive source, provided on the fan frame;
the partially luminous fan blade of claim 1 , assembled with the drive source; and
at least one first light source, disposed on the fan frame and facing the light guide bracket.
9. The fan according to claim 8 , wherein the fan comprises a light guide ring arranged on the fan frame and is directly observable from the fan frame, and at least one second light source facing the light guide ring.
10. The fan according to claim 9 , wherein the fan frame comprises at least two half shells assembled with each other.
