Bitmap Data Transmission for LED Curtain Light Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission processes to LED lights in curtains often incur delays or data loss, affecting lighting effects and user experience due to the large amount of data required for controlling a large number of LED lights.
Innovation Solution
A method that converts dot matrix graphic data into bitmap image data for transmission, which is then parsed by the controller to control individual LED lights, reducing data volume and minimizing transmission delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional data transmission methods are used to control a large number of LED lights, then the lighting effects can be achieved, but transmission delays and data loss occur affecting user experience
Solution Approach 1:
The patent segments the large amount of LED control data into multiple data packets for transmission. Each packet contains control information for a specific portion of LED lights, allowing parallel transmission and reducing overall transmission time while maintaining data integrity through individual packet acknowledgment and retransmission mechanisms.
Solution Approach 2:
The system performs preliminary actions by pre-processing and compressing LED control data before transmission. The controller prepares optimization instructions in advance that reduce the data volume needing transmission, and establishes transmission protocols beforehand to prevent data loss and minimize delays during actual data transfer.
2Adaptability or versatility
If control data is transmitted to all LED lights, then comprehensive lighting effects are achieved, but data transmission pressure and network load increase
Solution Approach 1:
The patent implements local quality by allowing different segments of LED lights to receive different control data packets with specific lighting parameters. Each data packet contains targeted control information for specific LED groups, enabling localized lighting effects while reducing the overall data transmission requirement compared to sending uniform control data to all LEDs.
Solution Approach 2:
The system applies partial action by transmitting control data only to the specific LED lights that need to change state, rather than broadcasting to all LEDs. The controller identifies which LED segments require updates and sends data packets only to those specific groups, reducing unnecessary transmission load while maintaining full lighting control capability.

AI summary
A light-emitting data transmission method includes obtaining display layout information of a lamp, and generating a dot matrix drawing interface on a display interface corresponding to the display layout information. The lamp includes a plurality of light-emitting units, and each curtain light is mapped to a coordinate point in the dot matrix drawing interface. The method also includes obtaining bitmap graphic data generated by receiving an external editing instruction from the dot matrix drawing interface, converting the bitmap graphic data into bitmap image data in a predetermined image format, and outputting the bitmap image data to a controller, so that the controller parses the bitmap image data into the light-emitting information corresponding to each light-emitting unit. The light-emitting information is used to control the corresponding light-emitting unit to emit light, such that light emitted by the plurality of light-emitting units are combined to form a predetermined light effect.
