Mobile phones are widely used as flashlights, but their camera light sources (typically LED flashes) are designed for short-range photography. They produce broad, scattered light that doesn’t illuminate far, making them poor substitutes for real flashlights. While external lenses exist to focus this light, they are often bulky, tricky to align, and incompatible with phone cases.
Core
Innovation
This invention introduces a sleek, custom-designed attachment that securely fits onto a mobile phone to focus its built-in camera light. It features a special lens mounted in a thin, precisely shaped holder that clips or sticks onto the phone using magnets, adhesive, or integration with existing camera bumps. The lens can be fixed or adjustable, and is carefully positioned to sit directly in front of the light source, greatly improving the beam’s focus and range.
What
Makes It New
Unlike earlier solutions, this device is:
- Ultra-thin and shaped to match specific phone models,
- Easy to attach, remove, or even integrate with existing phone cases,
- Capable of either fixed or adjustable focus (sliding or telescoping), and
- Dual-purpose—enhancing light range while protecting the camera module.
It overcomes alignment issues and bulkiness by self-centering around the phone’s existing camera structure and working seamlessly with everyday phone use.
Tangible Benefits
- Turns a phone’s LED light into a focused beam capable of lighting up to 200 meters ahead.
- No need for a separate flashlight—more convenience on the go.
- Slim design won’t interfere with phone use or case protection.
- Optional adjustable focus adds flexibility for different lighting needs.
Broader
Impact
This invention enhances phone usability in daily life, emergencies, and outdoor activities. By making existing hardware (the camera LED) more functional without adding bulk or complexity, it contributes to more sustainable and efficient gadget use—reducing the need to carry or purchase extra devices.
