Abstract: Disclosed herein is a lighting device with adjustable technical effects using few extraction electrodes to keep the cost low and the device simple, the device including: at least one filament group, wherein each filament group includes at least one filament, each filament includes at least one first light emitting unit and at least one second light emitting unit, which are connected in anti-parallel, and the first light emitting unit and the second light emitting unit have different light attributes from each other; and a light attribute adjusting unit, which is connected to both ends of each filament group to adjust a light attribute of light emitted from the lighting device, wherein the light attribute of the emitted light can be different from the light attribute of any light emitting unit.

Abstract: Provided is a light-emitting device for a display, and a method that includes light sources distributed on one or more strips, several light sources are arranged on each strip, and are electrically connected in a matrix manner, the number of rows and columns of the matrix are greater than 1, and each row and column of the matrix have a control line to receive a control signal; and a control unit that acquires a video signal to be provided to the display screen, from a signal source of the display screen, determines color and brightness of each light source according to the video signal, wherein each light source corresponds to a partial pixel area in the outermost periphery of a display area, and for each matrix, sequentially control each row or column of light sources in the matrix to emit light based on color and brightness within one light-emitting period.

Abstract: The present application relates to a system for controlling a lamp, a circadian lamp and a holiday lamp. The system for controlling the lamp includes: a timing module, configured to acquire information about local time; and a lamp control module, configured to control the lamp to operate in a color temperature control mode, wherein in the color temperature control mode, the lamp control module provides, on the basis of the information about the local time, the lamp with a control signal, the control signal is used to adjust the color temperature and/or brightness of the lamp.
