Solution Overview
Problem
Existing lighting devices in the show-business and entertainment sector face challenges in efficiently and reliably displaying unique identifiers and production information due to label degradation, removal, and complex communication protocols, which are inconvenient and difficult to update.
Innovation Solution
Equipping lighting devices with a robust liquid-crystal display connected to the circuitry to present electrical marker signals, such as QR codes, allowing easy reading and updating of unique identifiers and production information without requiring specific communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a label with visual code (QR code) is applied to lighting devices, then device identification is enabled, but the label degrades and can be removed during handling and transport
Solution Approach 1:
The patent creates a visual copy of the device's identification data (serial number, UID, production lot) by projecting it as a QR code through the light beam. This projected copy replaces the physical label, eliminating degradation and removal issues while maintaining identification functionality. The QR code is generated from the device's internal memory and projected optically during operation.
2Loss of information
If complex communication protocols are used for device identification, then precise device information can be transmitted, but the system becomes difficult to operate and update
Solution Approach 1:
The patent replaces complex electronic communication protocols with a simple optical projection system. Instead of requiring specialized readers and communication interfaces, the device projects its identification information as a visual QR code that can be scanned by standard QR code readers on smartphones or other devices, dramatically simplifying operation while maintaining information accuracy.
3Loss of information
If physical labels are used for device marking, then unique identifiers can be displayed, but the labels require specific lighting conditions for reading and are difficult to update
Solution Approach 1:
The patent transforms the static physical label into a dynamic optical projection. The QR code is projected through the device's light beam, which can be directed anywhere and adapted to various lighting conditions. The projection can be activated on demand and updated by changing the data in the device's memory, providing flexibility and adaptability that fixed physical labels cannot match.

AI summary
A lighting device that can be used, for example, in the show-business and entertainment sector includes an electrically powered light generator, as well as electrical circuitry configured to produce electrical signals for driving the light generator. The electrical circuitry has stored within it an electrical marker signal uniquely associated to the lighting device, and a visual display unit is coupled to the electrical circuitry, where the visual display unit is configured to display the electrical marker signal as a visually recognizable optical mark, such as a QR code.
