Light transmission fan blade and ceiling fan
A ceiling fan includes a supporting rod, an electric device, a light-emitting component, a housing and a fan blade. The electric device is arranged around the supporting rod. The light-emitting component is arranged around the supporting rod. The housing covers the electric device and the light-emitting component. The fan blade is driven to rotate by the electric device, and is provided with a light inlet toward the light-emitting component. The light emitted by the light-emitting component enters the interior of the fan blade from the light inlet. The light is reflected and transmitted within the interior of the fan blade, and subsequently emitted out of the blade surface element. Due to the reflection effect, the light is diffused, so that the light emitted from the blade surface element of the fan blade can illuminate a larger area, and the light emitted from the blade surface element is softer.
1 . A light transmission fan blade comprising:
an upper shell;
a blade surface element; and
a light inlet arranged on a side of the fan blade, wherein the upper shell is combined with the blade surface element to form a curved shape with a light channel integrated inside, the light channel is connected to the light inlet for light entering the fan blade, and the light channel is configured to match the curved shape,
wherein the light entering the light channel from the light inlet is reflected and transmitted within the fan blade before emitting out of the blade surface element.
2 . The fan blade of claim 1 , wherein an edge of the upper shell comprises a frosted surface, and the blade surface element comprises a smooth surface.
3 . The fan blade of claim 1 , wherein the upper shell is provided with textured decorative lines or etchings.
4 . The fan blade of claim 1 , wherein a plurality of reflective surface elements are provided on an inner surface of the light channel, and the plurality of reflective surface elements are configured to reflect and transmit the light from the light inlet to an end of the fan blade distal from the light inlet.
5 . The fan blade of claim 1 , wherein the internal structure of the fan blade between the light inlet and the blade surface element includes light-transmitting material.
6 . A ceiling fan comprising:
a supporting rod;
an electric device arranged with respect to the supporting rod;
a light-emitting component arranged with respect to the supporting rod;
a housing covering the electric device and the light-emitting component; and

wherein the light-emitting component emits light to enter the fan blade from the light inlet, the light is reflected and transmitted within the fan blade, and the light is emitted out of the blade surface element of the fan blade.
7 . The ceiling fan of claim 6 , wherein a plurality of reflective surface elements are provided on an inner surface of the light channel, and the plurality of reflective surface elements are configured to reflect and transmit the light emitted by the light-emitting component from the light inlet to an end of the fan blade distal from the light inlet.
8 . The ceiling fan of claim 6 , wherein the internal structure of the fan blade between the light inlet and the blade surface element includes light-transmitting material.
9 . The ceiling fan of claim 6 , wherein an edge of the upper shell comprises a frosted surface, and the blade surface element comprises a smooth surface.
10 . The ceiling fan of claim 6 , wherein the upper shell is provided with textured decorative lines or etchings.
11 . The ceiling fan of claim 6 , wherein the supporting rod is connected to a first mounting member, a plurality of the light-emitting components are arranged on an outer surface of the first mounting member, and the plurality of the light-emitting components are arranged circumferentially around the first mounting member and the supporting rod.
12 . The ceiling fan of claim 11 , wherein a plurality of the fan blades are assembled to allow the light inlets of the plurality of fan blades surround the first mounting member.
13 . The ceiling fan of claim 6 , wherein the electric device includes a rotor and a stator, wherein the stator is connected to the supporting rod, the rotor is connected to the housing, and the housing is connected to the fan blade.
14 . The ceiling fan of claim 13 , wherein the housing comprises a first sub-housing connected to the rotor, and
wherein a first bearing is arranged between the first sub-housing and the supporting rod.
15 . The ceiling fan of claim 14 ,
wherein the housing comprises a second sub-housing connected to an upper surface of the fan blade,
wherein the second sub-housing is connected to the first sub-housing via a connecting plate, and
wherein a second bearing is arranged between the connecting plate and the supporting rod.
