Referring to fig. 1-4, the present invention provides the following technical solutions: a circular OLED lamp light guide plate comprises a second mounting frame 12, a limiting rod 2 is mounted at the top of the second mounting frame 12, a penetrating third mounting groove 9 and a penetrating fourth mounting groove 13 are formed in the second mounting frame 12, a third light guide plate 10 is mounted in the third mounting groove 9, a fourth light guide plate 11 is mounted in the fourth mounting groove 13, a first mounting frame 5 is sleeved on the limiting rod 2, a penetrating first mounting groove 4 and a penetrating second mounting groove 8 are formed in the first mounting frame 5, a first light guide plate 6 is mounted in the first mounting groove 4, a second light guide plate 7 is mounted in the second mounting groove 8, the first mounting frame 5 is pulled to enable the first mounting frame 5 to rotate on the limiting rod 2, so that the relative position between the first mounting frame 5 and the second mounting frame 12 is adjusted, the first light guide plate 6 and the second light guide plate 7 are driven to rotate through the first mounting frame 5, thereby adjusting the relative positions between the first and second

light guide plates

6 and 7 and the third and fourth

light guide plates

10 and 11, and thus adjusting the refractive index of the device.

Further, 2 periphery of gag lever post is close to the top of first mounting bracket 5 and closes soon and is connected with spiro 1, and spacing ring 3 is installed to 1 bottom of spiro, and after the relative position between first mounting bracket 5 and the second mounting bracket 12 was adjusted, screw 1 on the rotation gag lever post 2 makes spiro 1 and spacing ring 3 move on gag lever post 2, supports first mounting bracket 5 through spacing ring 3, makes the relative position between first mounting bracket 5 and the second mounting bracket 12 adjust the back more firm.
