Ceiling fan upper light

A ceiling fan upper light, coupled to a ceiling fan configured to attach to a ceiling surface, the ceiling fan having a ceiling fan body and at least one blade, wherein the ceiling fan upper light is disposed between the ceiling surface and the at least one blade, the ceiling fan upper light comprising:

• a light casing, having two seats and at least one side wall, a first space being defined between the seats and the at least one side wall, the at least one side wall surrounding the first space, the seats being fixed to a top and a bottom of the at least one side wall respectively, the seats being made of an opaque material, the at least one side wall being made of a light-pervious material, the light casing being fixedly connected to the ceiling fan body;
• at least one shielding plate, fixedly connected to at least one of the seats, the at least one shielding plate being annularly disposed in the light casing, the at least one shielding plate being located in the first space, a second space being defined between the at least one shielding plate and the seats, the at least one shielding plate being made of an opaque material, the at least one shielding plate shielding the second space;
• at least one groove, annularly disposed inside the light casing, the at least one groove being adjacent to an inner side of the at least one side wall, an opening being formed on one side of the groove adjacent to the at least one side wall, the at least one groove being recessed from the side adjacent to the at least one side wall toward another side away from the at least one side wall along an extending direction of the at least one side wall, the at least one groove being located outside the at least one shielding plate;
• an LED light-emitting module, including a plurality of light-emitting diodes, the light-emitting diodes being annularly disposed in the light casing, the light-emitting diodes being located in the at least one groove, the light-emitting diodes emitting light toward the opening of the corresponding groove, the light-emitting diodes not extending out of the at least one groove;
• wherein when the ceiling fan is connected to a power source, the ceiling fan supplies power to the LED light-emitting module so that the light-emitting diodes emit light toward the opening of the groove, and the groove restricts a light irradiation direction to prevent the light from directly irradiating an outside of the at least one side wall so that the at least one side wall displays light colors of the light-emitting diodes.
