Abstract
A light emitting diode-based skin cosmetic device includes a first light emitting panel, a second light emitting panel, a first narrow band filter, a second narrow band filter and an optical window. The first light emitting panel is connected with the second light emitting panel at one side and an angle is formed between the first light emitting panel and the second light emitting panel. Two sides of the optical windows are connected with the first light emitting panel and the second light emitting panel together to form a triangle structure and the angle is faced toward the optical windows. The first and second narrow band filter is disposed on one surface of the first light to emitting panel and one surface of the second light emitting panel respectively.
