1. A lighting device comprising:
an N-sided polygonal light guide plate comprising N light incident surfaces and two opposite light emitting surfaces, wherein each of the light incident surfaces is perpendicular to the light emitting surfaces, and N is a natural number more than or equal to 3; N edge frames, wherein each of the edge frames corresponds to one of the light incident surfaces, and each of the edge frames comprises:
a main body bendedly formed by a first, a second, and a third adjacent rectangular planes, wherein the main body comprises an accommodating groove and an opening;a first clamp member and a second clamp member symmetrically extending outward respectively from the edges of the first and the third rectangular planes, wherein a top and a bottom surfaces of the light guide plate corresponding respectively to the light emitting surfaces are respectively clamped by the first and the second clamp members of the edge frame, and the corresponding light incident surface is inserted in the main body of the edge frame through the opening of the main body of the edge frame, such that the corresponding light incident surface is accommodated in the accommodating groove of the edge frame; anda first fixing element and a second fixing element respectively disposed on a first and a second ends of the main body of the edge frame, wherein the edge frame is pivoted to the second and the first fixing elements disposed on the main body of an adjacent one of the edge frames respectively by the first and the second fixing elements thereof, and the first fixing element of the edge frame accommodates the second fixing element of the adjacent one of the edge frames; and at least one light source disposed in the accommodating groove of one of the edge frames and adjacent to the corresponding light incident surface, wherein when light is emitted from the light source, the light enters the light guide plate from the corresponding light incident surface, and is emitted through the two light emitting surfaces. |
