摘要： An aroma diffuser with changing of rotating pattern lighting uses a patterned light-transmitting film designed to cover the outside of a light-emitting device, and one side of the patterned light-transmitting film is combined with a rotating ring driven by a transmission device. The light-emitting device radiates the light source to the patterned light-transmitting film, and the light effect of the pattern is transmitted to the outer light-transmitting casing through the patterned light-transmitting film to display the aesthetics of patterned light and shadow. The rotating ring can rotate the patterned light-transmitting film to change the lighting effect of its pattern or text. The light-emitting device can use different colors to generate light to reflect the graphics of the patterned light-transmitting film as colored light and shadow displayed in the light-transmitting casing, thereby producing light decoration or lighting and heating the aroma substances filled in the aroma diffuser.
