A lighting fixture as recited in claim 1, wherein said light guide plate (300) is a wedge-shaped light guide plate, and a thickness of said light guide plate (300) on one side of said light-in surface (310) is greater than a thickness of said light guide plate (300) on another side opposite to said light-in surface (310).

7. The lighting fixture as claimed in claim 1, wherein the light incident surface (310) is provided with a light splitting groove (330), the light splitting groove (330) comprises a main light incident surface (331) and a light splitting surface (332), the light emitting body (200) is located in the light splitting groove (330), the front surface of the light emitting body (200) is opposite to the main light incident surface (331), and the side surface of the light emitting body (200) is opposite to the light splitting surface (332).

8. A lighting fixture as recited in claim 7, wherein said light guide plate (300) is provided with a reflecting surface (340), said reflecting surface (340) being opposite to said light entrance surface (332), said reflecting surface (340) being configured to reflect light rays to re-enter said light guide plate (300) in case said light rays enter said light guide plate (300) from said light entrance surface (332) and reach said reflecting surface (340).

9. The lighting fixture according to claim 1, wherein the light emitter (200) comprises a plurality of sub-light emitters (210) arranged at intervals, the light incident surface (310) is provided with a plurality of light scattering structures (350), the plurality of light scattering structures (350) and the plurality of sub-light emitters (210) are in one-to-one correspondence, and the light scattering structures (350) are used for enlarging the light incident angle of the sub-light emitters (210) on the light incident surface (310).

10. A lighting fixture as recited in claim 1, further comprising a power driver (600) and a power box (700), wherein said power driver (600) is disposed within said power box (700), said power box (700) is disposed on a side of said base plate (100) opposite to said light emitter (200), said base plate (100) is provided with a threading hole (130), and a power line of said light emitter (200) is connected to said power driver (600) through said threading hole (130).
