    You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belvacv doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet.

That's why he created Lampbrella, a lamp post with its own rain sensing umbrella.

The designer says he came up with the idea after watching people get wet on streets in Russia. "Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬) built into a street lamp,"he said.

The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors (传感器)then ensure that the umbrella offers pedestrians shelter whenever it starts raining.

In addition to the rain sensor, there's also a 360 motion sensor on the fiberglass street lamp which detects whether anyone's using the Lampbrella. After three minutes of not being used the canopy is closed.

According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each Lampbrella would offer enough shelter for several people. Being     installed at 2 meters off the ground  it would only be a danger for the tallest of pedestrians.

While there are no plans to take Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department and insists this creation should be installed on the street where a lot of people walk but there are no canopies to provide shelter.
