All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides a MiniLED lamp, including: a plurality of MiniLED light sources 3; the video signal control component 1 decodes the video signal and outputs a dimming signal according to the video signal sent by the video playing component; the driving component 2 sends a driving voltage to each MiniLED light source 3 according to the dimming signal.
The video signal control component 1 receives the video signal, decodes the video signal into a dimming signal and outputs the dimming signal to the driving component 2, and the driving component 2 sends different driving voltages to each MiniLED light source 3 according to different dimming signals, so that a single lamp can display pictures or characters; the MiniLED light source 3 is used as a light-emitting light source, the display screens with different shapes are formed by the MiniLED light sources, each MiniLED represents one pixel, and one lamp can realize control of the pixels, so that a single lamp is designed into the display screen capable of displaying pictures or characters, and can be designed into an energy-saving and environment-friendly point light source lamp, the volume of the MiniLED light source 3 is small, and the pictures or the characters can be displayed more clearly by controlling each MiniLED light source 3.
In some embodiments, each MiniLED light source 3 is connected common cathode. The common anode connection of the MiniLED light source 3 can lower the voltage for driving the red light lamp, shorten the service life of a product and is not beneficial to energy conservation, so the MiniLED light source 3 adopts common cathode connection.
In some embodiments, the driving component 2 is a constant current common cathode driving chip, the constant current common cathode driving chip is connected to each MiniLED light source 3, and each MiniLED light source 3 is single-point controlled by the constant current common cathode driving chip to display pictures or characters.
