VEHICLE LAMP - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240262284 titled 'VEHICLE LAMP
Simplified Explanation: This patent application describes a vehicle lamp with a light source that adjusts its drive current based on temperature and surrounding illuminance levels.
- Light source emits light with a drive current from a light source drive circuit.
- Temperature sensor measures temperature of the light source or its surroundings.
- Drive current is reduced if temperature exceeds a set threshold.
- Control start temperature is lower when surrounding illuminance is high.
- Illuminance measurement sensor determines illuminance levels of the vehicle surroundings.
Key Features and Innovation:
- Adaptive drive current control based on temperature and illuminance levels.
- Enhanced efficiency and longevity of the light source.
- Improved safety and visibility for the vehicle.
Potential Applications:
- Automotive lighting systems.
- Smart lighting solutions for vehicles.
- Energy-efficient lighting technology.
Problems Solved:
- Overheating of vehicle lamps.
- Inefficient use of energy in lighting systems.
- Inadequate visibility in varying lighting conditions.
Benefits:
- Extended lifespan of vehicle lamps.
- Energy savings through optimized drive current.
- Enhanced safety for drivers and pedestrians.
Commercial Applications: Title: Adaptive Vehicle Lamp Technology for Enhanced Safety and Efficiency This technology can be applied in automotive manufacturing for the development of advanced lighting systems that improve visibility and energy efficiency. It can also be integrated into smart lighting solutions for vehicles, catering to the growing demand for sustainable and innovative automotive technologies.
Questions about Adaptive Vehicle Lamp Technology 1. How does the temperature sensor in the vehicle lamp work to regulate the drive current? The temperature sensor measures the temperature of the light source or its surroundings, triggering a reduction in the drive current if the temperature exceeds a set threshold. This helps prevent overheating and ensures optimal performance of the light source.
2. What are the potential benefits of adjusting the control start temperature based on surrounding illuminance levels? By setting a lower control start temperature when the surrounding illuminance is high, the vehicle lamp can operate more efficiently in bright conditions. This adaptive feature enhances the overall performance and longevity of the lighting system.
Original Abstract Submitted
a vehicle lamp that includes: a light source that emits light due to a drive current that is supplied from a light source drive circuit; and a temperature sensor that measures a temperature of the light source or surroundings of the light source, wherein the light source drive circuit reduces the drive current when the temperature that has been measured by the temperature sensor becomes equal to or greater than a control start temperature, and, in a case in which an illuminance of surroundings of a vehicle that has been measured by an illuminance measurement sensor is equal to or greater than an illuminance threshold, the control start temperature is set to be lower than in a case in which the illuminance of the surroundings of the vehicle is less than the illuminance threshold.
