Wind-Power Bicycle Lamp


The best designers of the red dot award: product design 2006: Hsieh Jung-Ya

Likewise, the designer Hsieh Jung-Ya from Taiwan belongs to the best of this year's red dot award: product design. He received the award “red dot: best of the best” for his wind-powered bicycle headlights. Hsieh Jung-Ya talked to us on the subject of “form and ecology”:


“The wind load was reduced through a streamlined design and creates the futuristic impression of a flying vehicle. The mathematically optimised fan blades make use of the wind to supply a powerful electricity generating effect – along with a highly efficient, durable LED headlight they provide natural, electric-generated illumination in an extremely small unit. This new wind-powered lamp reduces battery pollution, frees users from the troubles of wiring and, since it is installed with ease and comfort on the handle bar, enhances the perceived value of the bicycle.”

The Wind-Power Bicycle Lamp: a worthwhile companion
The forms of bicycle lamps have always followed developments in the bicycle. The turn of the century, for instance, saw the advent of carbide lamps, which were unreliable and produced only weak illumination.

Today, bicycle headlights and their designs are matched to ever more sophisticated bicycles and their forms correspond to the most recent bicycle models. The wind-powered bicycle headlight combines an innovative yet almost self-evident energy-producing technology with a reduced language of form. It is powered by converting the wind force produced by a moving bicycle into light. More precisely, the wind energy feeds a low-power yet extremely bright LED lamp with a DC voltage of 3.4 volts and 50mA. Thus, at night, the headlight offers good quality, powerful illumination of up to 1700 lux.

Both a highly economical and ecological aspect of this design: the energy produced by the moving bicycle is stored in a rechargeable lithium battery – avoiding the need for replacement batteries. The design of this headlight is an expression of its functionality, giving it a lightweight and natural appearance. Its housing features a visible high-efficiency micro generator which, when the bicycle is moving at 21 km/h, produces continuous power of 3.5 volts at 70mA for the LED and the lithium battery. The bicycle headlight can be easily mounted on any bicycle frame and integrates well due to its reduced language of form. New approaches in thinking thus meaningfully combine a simple physical principle with current and trendsetting technologies. The headlight is given a new form and turns into a highly worthwhile companion.

About Hsieh Jung-Ya
Hsieh Jung-Ya was born in Taiwan in 1967. After working for various design offices, he set up his own studio, officially presented under the name Duck Image in 1999. Located in central Taiwan, where craftsmanship and techniques have a long tradition, the studio covers  a wide range of communication to industrial design, creating for instance packaging, web design and architectural concepts. Despite the complexity of the different tasks, Hsieh Jung-Ya’s products and designs always exemplify the principles of Eastern philosophy such as simplicity. Hsieh Jung-Ya also holds a teaching position in the industrial design department at Da Yeh University and runs his own material research laboratory.
