Research And Design Of Movie And TV LED Lamp Based On Bluetooth Communication

The rapid development of the economic and cultural industries has brought a lot of demand for film and television LED lights.The development of a digital controller for film and television LED lights with multiple lighting mode functions and wireless communication has high market value.Article first introduces the research background and significance of film and television LED lamps,describes the development of film and television lighting and film and television industry,and the source of film and television lamp light sources;introduces the research status of the topic at home and abroad,the research of LED lamp control system and the film and television LED lamps at home and abroad Describe the status quo of development.Then based on the functional requirements and hardware requirements of the film and television LED lamp system,the system architecture design of the film and television LED lamp and the working principle of the system are explained.Considering the requirements of the current film and television LED lights for the microprocessor,the 32-bit chip is established as the microprocessor chip;from the current market share and development cost considerations,Android is selected as the system development platform of the host computer;from the uniformity of light Consider the constant current drive scheme for consideration;choose the Bluetooth 4.2 wireless communication scheme from the perspective of low power consumption,stable transmission and cost.Immediately following the needs of film and television LED lights,the system hardware circuit was designed,including LED driver module circuit,microprocessor module circuit,Bluetooth module circuit and power module circuit.Then introduces the design and development of the system software part,including the design of the Android terminal interface,the design of the microprocessor software program and the design of the communication protocol.Finally,the test and result analysis of the film and television LED light system are carried out,including hardware test,software test and overall display effect test.The test result shows that all the expected functions can be achieved.The display screen can correctly display the functions and parameters of the film and television LED lights.Android applications and film and television LED lights can be connected and communicated normally to control the film and television LED lights,and adjust the color temperature mode,color mode and special effect mode.At the same time,through the keys on the control panel and the EC11 switch encoder,the function conversion and parameter adjustment can also be achieved.Film and television LED lights realize the functions of 2800 K to 10000 K color temperature fully adjustable,0 to 360 ° color full color display and preset multiple filters and lighting special effects.The film and television LED lights designed in this paper can meet the market demand and bring good economic benefits.
