From a real prototype to a 60 cm design.
The actual exhibition prototype shows a polyhedral rotor within a protective frame. The supplied 60 cm concept combines a solar panel, turbine, battery and LED on one pole. A photograph alone cannot verify the final components or electrical output.

These specifications were supplied for planning. Rated output, rotor start, noise, IP ratings and rainy-day autonomy require final-product tests and on-site validation. Controller design must also confirm charging compatibility among the 12 V generator, 18 V panel and 12.8 V battery.

Move the wind. Watch the light change.
Move the slider to explore rotor speed, illustrative wind output and LED brightness. In battery-assist mode, wind reduces battery draw while the battery keeps the lamp lit.

Educational simulation only. No measured power curve or rated wind speed was supplied for the 60 cm unit, so the curve arbitrarily assumes 50 W at 10 m/s (200 W is the proposed generator rating). LED load is 50 W; battery-assist mode assumes a charged battery. Conversion and charging losses are excluded. A rotor starting at 1.8 m/s does not prove useful battery charging at that speed.Wind speed and power: U.S. Department of Energy ↗

Educational calculation only. As in the existing simulator, the 60 cm rotor is arbitrarily assumed to produce 50 W at 10 m/s, with an assumed 0 W below 1.8 m/s applied to all four sizes. For other sizes, rotor height is assumed to scale with diameter, so intercepted area scales with diameter squared; a 200 W calculation cap is used for all four sizes. The wind trace is generated, not recorded. Rotor start speed does not establish charging start speed, and these values are not measured output, battery charging, or guaranteed product performance.Wind speed and power: U.S. Department of Energy ↗
03 / Night scene
A continuous path after dark.
For trails and campsites, begin with an 8–12 m spacing concept. Final distance depends on path width, trees, local terrain, target illuminance and uniformity.
Trail and campsite rendering · not a completed installation
Light that makes a place memorable.
For trails and waterfront walks, we propose layouts that consider color and spacing between lights.
04 / PLACE & EXPERIENCE
A place to walk, pause and take pictures.
Two supplied concepts combine waterfront lighting with visitors' experience. Project design should consider colors, brightness, safe circulation and spill light near homes.

THE MAKER
From the founder
CEO Sang Wook Han (Han Sang-wook) developed the hybrid landscape lighting concept to make wind visible as moving sculpture and turn stored energy into a shared nighttime experience.

06 / Where it belongs
For places where people walk and linger.
Every site has different walking patterns, ambient brightness and surroundings. Spacing and lighting should be planned accordingly.

07 / PERFORMANCE SCENARIOS
Balance daytime charging with nighttime use.
Solar can recharge the battery by day, while electricity actually generated by wind can offset LED use at night. If wind power is below LED demand, the battery drains more slowly; any surplus may charge it. A 1.8 m/s rotor start does not establish useful charging power.
Nominal battery384 Wh
12.8 V × 30 Ah
Assumed usable energy307 Wh
80% of nominal
50 W LED for 6 h300 Wh/night
Without dimming
Day: solar charges the battery → night: the LED and wind generation can run together → next day: solar replenishes what was used. Rotation alone does not tell us the actual charging power.
Adjust assumptions
Solar rating: 100 W; battery: 384 Wh (80% assumed usable). Enter the assumed wind power delivered while the LED is on. Only wind hours that overlap the lighting hours are counted.
—Next-day solar input (example)
—Wind input during nighttime LED use
—Nighttime LED use
—Night battery change (− draw / + charge)
—Daily energy balance (before storage cap)
—Full battery, no wind/sun: nights
—Full battery, no wind/sun: hours
—Full battery with entered wind hours
Night wind reduces battery draw.
For example, a 50 W LED running for six hours uses 300 Wh. If wind delivers an average 10 W during those hours, 60 Wh comes from wind and the battery supplies about 240 Wh overnight. If solar replenishes 225 Wh the following day, the simplified daily deficit is only 15 Wh. During rain and still air, neither source helps; 307 Wh usable battery energy lasts about one full-power night. Three to five nights needs dimming or measured recharging.
Night battery change = (mean wind input × overlapping hours) − (average LED draw × lighting hours) Daily balance = night battery change + following daytime solar input
Illustrative continuous runtime starts with a full battery, assumes constant wind power for the entered overlap hours and then no wind. Timer limits, system losses and the battery storage cap need separate review.

The assumed 10 W wind supply and 75% solar performance factor are illustrations, not measurements. Rotor movement at 1.8 m/s is not a guaranteed charging rate. Battery capacity limits, charging controls, idle draw, shade, season, temperature, aging and CCTV or other loads must be checked in the field. Small-wind guide and sources ↗
08 / Project planning
Plan spacing and upkeep around the site.
Spacing of 8–12 m on one side of the path is an initial concept. Confirm sunlight, turbulence, foundations, light distribution and any CCTV or insect-related accessory loads before final specification.
