LIGHT-EMITTING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18466405 titled 'LIGHT-EMITTING DEVICE
Simplified Explanation
The present disclosure describes a light-emitting device that can detect a failure in a light-emitting circuit without affecting the waveform of the current supplied to the light source.
- The light-emitting device includes a light-emitting circuit with a light source element and a power supply that provides electric charges to the circuit.
- The light-emitting circuit is positioned between a power supply node and a ground node.
- The power supply is connected to the power supply node through a power supply line.
- A monitor is used to detect any abnormal state in the light-emitting circuit by monitoring the voltage of the power supply line or the internal voltage of the power supply.
Potential applications of this technology:
- Lighting systems: This technology can be used in various lighting systems, such as LED lights, to detect failures in the light-emitting circuit without affecting the light output.
- Display devices: It can be applied in display devices like LED screens to identify any abnormalities in the light-emitting circuit without impacting the visual display.
- Automotive lighting: This technology can be utilized in automotive lighting systems to detect failures in the light-emitting circuit, ensuring proper functioning of headlights, taillights, and other lighting components.
Problems solved by this technology:
- Failure detection: The light-emitting device allows for the detection of failures in the light-emitting circuit, enabling timely maintenance or replacement of faulty components.
- Waveform preservation: By detecting failures without affecting the waveform of the current supplied to the light source, the device ensures uninterrupted and consistent light output.

- Improved reliability: The ability to detect failures in the light-emitting circuit enhances the overall reliability of the light-emitting device.
- Cost savings: Timely detection of failures allows for prompt maintenance or replacement, reducing potential downtime and costly repairs.
- Enhanced performance: By preserving the waveform of the current supplied to the light source, the device ensures consistent and high-quality light output.
Original Abstract Submitted
The present disclosure allows a light-emitting device to detect a failure of a light-emitting circuit without affecting the waveform of a pulse current to be supplied to a light source element. The light-emitting device includes: a light-emitting circuit including a light source element; and a power supply configured to supply electric charges to the light-emitting circuit. The light-emitting circuit is provided between a power supply node and a ground node. The power supply is connected to the power supply node via a power supply line. A monitor detects an abnormal state of the light-emitting circuit by monitoring the voltage of the power supply line or the internal voltage of the power supply.
