Needing 13 more points to hit that mark before the start of the game, Bryant scored his 13th and 14th points on a short jumper with just over a minute remaining before half-time.
At the age of 34, the 14-time All-Star became only the fifth player to reach the milestone, emulating Hall of Famers Kareem Abdul-Jabbar (38,387), Karl Malone (36,928), Michael Jordan (32,292) and Wilt Chamberlain (31,419).
"It's a huge honor, to say the least," Bryant told reporters earlier this week about the prospect of breaking the 30,000-point barrier.
"Whenever you hear those kinds of names, you think about the amount of players that have played this game, and then to be in that kind of company, it's always extremely, extremely special." (Reporting by Mark Lamport-Stokes in Los Angeles; Editing by Greg Stutchbury)
