A portable LED lighting device with adjustable brightness settings, including a light module, battery pack, and external switches, featuring high-brightness LEDs and indicator LEDs for mode and battery life indication, allowing users to configure settings via a microcontroller with EEPROM for persistent memory, enabling multiple modes and settings such as bicycle mode and special mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light uses fixed high brightness to ensure visibility, then the rider is more visible and path is well illuminated, but battery life is reduced
Solution Approach 1:
The patent implements adjustable brightness levels that allow the light output to be dynamically changed based on environmental conditions. The system transitions from a fixed brightness design to a dynamic one where users can select between multiple brightness levels (e.g., high, medium, low) to match varying lighting conditions, thereby optimizing battery consumption while maintaining adequate visibility.
Solution Approach 2:
The patent changes the operational parameter of light brightness from a fixed value to a variable with multiple selectable levels. By implementing different brightness modes (high, medium, low), the system allows parameter adjustment to match environmental lighting conditions, reducing energy consumption when maximum brightness is not required while maintaining visibility when needed.

AI summary
A portable lighting device for illuminating a path engaged by a user, or enabling the user to be seen by other cyclists, pedestrians, motorists and the like is provided. Advantageously, the portable lighting device is small (configured to fit in the user's palm), light (configured to be comfortably attached to a user's bicycle frame, helmet or carried in the hand of the user) and durable (configured to be usable in any weather condition). In addition, the light is conveniently powered by an attachable battery pack and may store variable brightness and mode settings for versatile usage. Moreover, the light utilizes a EEPROM to store the user re-configured settings in conjunction with adjustably bright high-brightness LEDs ranging upwards of 3000 lumens to provide the user with an excellent lighting tool.
