A light control method and apparatus, and a storage medium are disclosed. The light control method includes: acquiring video data information from the video source device; obtaining color data information of pixels in a preset region in a frame picture according to the video data information; generating a corresponding light control signal according to the color data information; and outputting the light control signal to a lamp bank to control an operating state of the lamp bank to match the video data information.

A ring flash light diffusion device includes a first converter ring configured to connect to a camera lens and a diffuser adapter. The diffuser adapter can be connected to a first end of the first converter ring. It also includes a flash ring connected to the diffuser adapter at a position along the length of the diffuser adapter and a ring flash connected to the flash ring. It further includes a light diffuser connected to the diffuser adapter such that light emitted from the ring flash passes through the light diffuser.

Self-contained devices, systems and methods for housing holiday lights in the form of icicles, and the like, in self-contained boxes that can easily be mounted and removed around house windows and eaves. The lights can be retractable and extendable downward from the boxes, and the lights can be remotely controlled by smart phones and the like. The boxes can have displays for holiday messages as well as speakers for playing music and messages. Another embodiment can include a drop down version where the lights drop down from a housing. Another version can include a fold out version where a support frame having upwardly protruding lights is rotated so that the lights extend below the housing.
