LONDON (Reuters) - The designers of London's Olympic torch have won the Design of the Year 2012 award, organizers announced on Tuesday.

London studio Barber Osgerby, a joint venture between Edward Barber and Jay Osgerby, was chosen from a field of 89 entries, and honored at a ceremony at London's Design Museum.

"Nothing is harder to get right than designing for the Olympics," said Design Museum director Deyan Sudjic. "The lightness and simplicity of Barber Osgerby's Olympic Torch does just that."

The torch is made of aluminum and perforated with 8,000 circular holes, each representing a single carrier of the torch as it makes its way to the opening ceremony in London on July 27.

The holes also act to reduce the weight of the torch and prevent heat from the flame being conducted to the bearer's hand, the Design Museum said.

Also unveiled on Tuesday were the Design of the Year category winners:

- Architecture Award 2012: London 2012 Velodrome/Hopkins Architects
