Philips Light Blossom LED Streetlamp Harnesses Wind And Solar Power

Streetlights aren’t usually considered part of the natural landscape. But the Philips Light Blossom comes close, with a uniquely organic design that collects all the power it needs from sun and wind.

The Light Blossom earns its name by taking a cue from the way flowers collect sunlight. During daylight hours, the “petals” of the lamp spread wide to optimize the position of their solar cells. Then, as darkness falls, the petals sweep upward so the LED arrays on the underside can provide light below. The directional downward light is designed to minimize the scattered light pollution that is a common effect of traditional streetlight designs. In addition, the Light Blossom is designed with integrated motion sensors, so it offers a low-light standby mode as well as brighter ambient lighting when people are nearby.

Solar power isn’t the only renewable energy source for the Light Blossom. On windy days, the petals automatically transition to a half-open position so they spin in the breeze, which the internal rotor converts to electricity.

The Light Blossom uses far less electricity than a traditional streetlight, but its biggest advantage is that it can be used anywhere, since it doesn’t need to be placed on a city power grid. And when it is used in a municipal setting, the Light Blossom can actually generate a surplus of power, which is then transferred back to the grid.
