Title:
filter assembly
Document Type and Number:
Japanese Patent JP7282972
Kind Code:
B6
Abstract:
A filter assembly includes a filter holder, a first filter set, a second filter set, a third filter set, and a fourth filter set. Filters of various functional types are systematically classified into three categories. A first category of filters is capable of changing light effect by rotating. The first category of the filters is served as the first filter set, which is connected to the filter holder, and the light effect is changed by the rotation of the first filter set relative to the filter holder. A second category of filters changes the light effect by two filters relatively rotating or synchronously rotating with the first category of the filters. Regardless of form of rotation, a third category of filters does not change the light effect. The third category of the filters is served as the fourth filter set, which is disposed on a side of the third filter set facing away from the filter holder. Through the above organic combination, a user may arrange filters at corresponding positions according to the categories of the filter sets, so as to realize different operation combinations, which can utilize functional characteristics of most filters, thereby lowering the threshold for using the filters.
