Kristin Chenoweth injured on The Good Wife set

Actress Kristin Chenoweth has been sent to hospital after being struck by a piece of lighting equipment on the New York set of The Good Wife.

The 43-year-old, best known for The West Wing and Glee, was put in a neck brace and taken away in an ambulance.

"A gust of wind blew a lighting silk out of place, striking actress Kristin Chenoweth," said TV studio CBS.

"All of us at the studio and the show are thinking about Kristin and wishing her a quick recovery."

Lighting silk is cloth used to soften or deflect artificial light or sunlight during shooting. It is sometimes stretched over a lightweight metal or plastic frame.

However, the studio's statement appeared to contradict an earlier account of the accident from Chenoweth's publicist.

Jill Fritzo told the Associated Press her client was hit by falling scaffolding.

A witness told celebrity website TMZ that Chenoweth appeared to have been "knocked out cold" after the accident, having apparently struck her head on concrete as she fell.

A fire department spokesman confirmed that a woman had suffered minor injuries on the set, but declined to identify her.

Chenoweth joined hit legal drama The Good Wife in a recurring role for its fourth season.

She plays a political reporter who tries to uncover dirt on the lead character, Alicia Florrick (Julianna Margulies) and her estranged husband Peter (Chris Noth), who is running for governor.

In The West Wing, she played feisty press secretary Annabeth Schott. Writer Aaron Sorkin briefly dated the actress, and their relationship partly inspired the character of Harriet Hayes in his TV show Studio 60 On The Sunset Strip.

Aside from her TV works, Chenoweth is also a renowned Broadway actress, having originated the role of Glinda in the hit musical Wicked, and won a Tony award for You're a Good Man, Charlie Brown in 1999.
