Kaman scored 26 points and Davis had 20. Los Angeles shot 54 percent from the field and hit 10-of-16 attempts from 3-point range.
Philadelphia, in the midst of a six-game road trip, failed in its bid for what would have been its first three-game winning streak of the season. The 76ers have only nine total victories.
Lou Williams led Philadelphia with 19 points. Allen Iverson, who has recently missed time with a sore knee, scored seven points while playing 29 minutes.
