The Irish duo defeated USA pair Eva Lee and Mesinee Mangkalakiri in three sets 21-15, 9-21, 22-11 in a pulsating final at the Ulster venue.
It was a second consecutive title for the combination after landing the Welsh Open crown seven days earlier and high hopes of an Italian title in Rome next weekend.
Their coach Pat Marron described the result as “a very good day for Irish badminton”.
“The French girls they defeated in the semi-finals are ranked 27th in the world while the Americans were in the early 30s. These are serious players to have overcome.”
Said Bing: “This means everything to me. I am so happy, this is one of the titles that I have wanted to win for a long, long time. The final was very exciting. We did well in the first set, made a lot of mistakes in our second, but for the third we did what Pat told us and went on to win.”
Ireland number one, former Irish Examiner National Junior Sports Star, Scott Evans, lost out in the singles semi-final stage to Marc Zwiebler of Germany (21-15, 21-7), having led at the halfway stage of both sets.
The German was subsequently defeated by Peter Mikklesen of Denmark (21-19, 21-18) in the final.
England’s Elizabeth Cann won the women’s singles title against the fancied Kaori Mori of Japan (21-19, 21-9).
The USA recorded a double doubles success. 2005 World champion Howard Bach partnered Khan Bob Malaythong to victory in the men’s doubles over German pair Michel Fuch, and Roman Spitko (21-15, 21-17).
In the mixed doubles Bach partnered Lee in their victory over Belgium’s Woutler Claes and Nathalie Decamps (21-10, 21-13).
