According to the utility model discloses light guide plate 2 can realize multi-direction light-emitting, excellent in use effect, in addition, light guide plate 2 simple structure, the space that not only occupies is little, and is with low costs moreover, light guide plate 2 can be applied to in the atmosphere lamp, and need not to set up multiunit atmosphere lamp and can realize multi-direction light-emitting, and the practicality is strong.

As shown in fig. 1, in some embodiments, the second surface 24 is provided with a first groove 241, an included angle between an inner circumferential surface of the first groove 241 and the second surface 24 is an obtuse angle, and it should be noted that, in a thickness direction of the light guide plate 2, the inner circumferential surface is inclined toward an outer side of the first groove 241 in a direction from the first surface 23 to the second surface 24, in other words, the inner circumferential surface of the first groove 241 is inclined toward the outer side of the first groove 241 in a direction from bottom to top. With this arrangement, light entering the light guide plate 2 through the light inlet portion 21 can be reflected on the inner circumferential surface of the first groove 241, so that the light path is changed and the light is emitted along the outer circumferential surface of the light guide plate 2, and multi-directional light emission of the light guide plate 2 is realized to a certain extent.

The shape of the light intake portion 21 may be various, such as a circle, a polygon or a ring, specifically, the light intake portion 21 is a ring, and a projection of the inner peripheral surface of the first groove 241 to the second surface 24 coincides with the light intake portion 21, thereby ensuring that light entering the light guide plate 2 through the light intake portion 21 can be totally incident on the inner peripheral surface of the first groove 241 to be reflected.

Accordingly, the light entering the light guide plate 2 through the light inlet portion 21 is refracted for the first time and then moves in the radial direction of the light guide plate 2 toward the peripheral side, and is emitted through the outer peripheral surface of the light guide plate 2, thereby realizing the light emission in the peripheral direction of the light guide plate 2.

As shown in fig. 4, in some embodiments, the first surface 23 of the light guide plate 2 is provided with a boss 231, and an outer circumferential surface of the boss 231 is inclined toward an outer side of the boss 231 in a thickness direction of the light guide plate 2 from a direction from the first surface 23 to the second surface 24. In other words, the boss 231 is inclined toward the outside of the boss 231 in a direction from below to above, and it can be understood that the inclination direction of the outer circumferential surface of the boss 231 is the same as the inclination direction of the inner circumferential surface of the first groove 241.

With this arrangement, a part of the light reflected by the inner peripheral surface of the first groove 241 is emitted along the outer peripheral surface of the light guide plate 2, and another part of the light is emitted in another direction after being reflected by the outer peripheral surface of the boss 231, so that light is emitted in another direction of the light guide plate 2 (the light propagation path in the light guide plate is shown by the dotted line with an arrow in fig. 2).

Specifically, the inclination angle of the outer circumferential surface of the boss 231 is 45 degrees, in other words, the included angle between the projection of the outer circumferential surface of the boss 231 on the longitudinal section of the boss 231 and the horizontal plane is 45 degrees. With this arrangement, the light reflected by the outer peripheral surface of the boss 231 can exit from the second surface in the thickness direction of the light guide plate 2.
