    摘要： A hair dryer includes a main body, a handle, and a diffuser. The diffuser includes a diffusing case having a rear side coupled to the main body. The main body is provided such that a front end of an outer wall surrounds a gas or air outlet, and a first coupling portion coupled with the diffuser is provided at the front end. The diffusing case includes a second coupling portion coupled to the first coupling portion while surrounding a gas or air inlet hole defined at the rear side. The first coupling portion includes a power transmitter to supply power to the diffuser, and the second coupling portion includes a power receiver to receive the power from the power transmitter.

    摘要： A method for designing a lens of a lighting device having a first spherical surface refracting light generated from an LED device that is a light source and a second spherical surface refracting the light passing through the first spherical surface includes determining an irradiation surface that is an area onto which light passing through the second spherical surface is irradiated, forming a reference circle disposed within the irradiation surface; designing a free curved surface of the first spherical surface by using light emitted from the LED device as an input direction vector and a coordinate within the reference circle as an output direction vector to calculate normal vectors, and designing a free curved surface of the second spherical surface by using light refracted by the first spherical surface as an input direction vector and a coordinate within the irradiation surface as an output direction vector to calculate normal vectors.

    摘要： A diffuser for a hair dryer includes a diffusing case having a rear side removably coupled to a main body of the hair dryer. Air or fluid discharged from the main body is introduced into the diffusing case through an inlet hole defined at the rear side. A n open surface is defined at a front side of the diffusing case such that the air introduced into the diffusing case is discharged to an outside through the open surface. The diffusing case includes a front circumferential portion surrounding the open surface. The front circumferential portion includes a first portion and a second portion. The first portion is at least partially located further forward of the second portion.
