Claim 6:
7. A backlight module comprising:
a back panel; and
a plurality of light sources arranged in an array on the back panel, wherein each of the light sources comprises a lens and a light bead arranged in an accommodating cavity of the lens, the lens comprises a light incident surface, a reflecting surface, and a light emitting surface;
wherein the light incident surface comprises a first light incident surface, a second light incident surface, a third light incident surface, and a fourth light incident surface, the first light incident surface, the second light incident surface, the third light incident surface, and the fourth light incident surface form the accommodating cavity, and a gap is defined between the light bead and the light incident surface;
wherein the reflecting surface comprises a first reflecting surface and a second reflecting surface, the first reflecting surface is connected to the second reflecting surface, a turning angle is defined between the first reflecting surface and the second reflecting surface, and an angle of the turning angle is greater than 0 degrees and less than 180 degrees; and
the light emitting surface comprises a first light emitting surface and a second light emitting surface, the first light emitting surface is connected to the first reflecting surface, and a plane where the first light emitting surface is located is perpendicular to a plane where the first reflecting surface is located; the first light emitting surface is connected to the second reflecting surface, and the plane where the first light emitting surface is located is perpendicular to a plane where the second reflecting surface is located; the second light emitting surface is connected to the first reflecting surface, and a plane where the second light emitting surface is located is perpendicular to the plane where the first reflecting surface is located; and the second light emitting surface is connected to the second reflecting surface, and the plane where the second light emitting surface is located is perpendicular to a plane where the second reflecting surface is located.
