The two light source guiding protrusions 112 of each curved light guiding element 11 are respectively inserted into the corresponding first accommodating areas 1011, and the light guiding plate 111 is located outside the fixing base 101. Each light source guiding-in bump 112 is located at one side of the corresponding light source module 102, and a plurality of light emitting diodes 1021 aligned in each light source module 102 corresponds to the light incident surface 1121 of the adjacent light source guiding-in bump 112.
When the lighting device 1 of the present embodiment is used, the two light source modules 102 of the light source supply assembly 10 are electrically connected with an external power source, the external power source supplies power to the circuit board 1020 of the two light source modules 102, the circuit board 1020 drives the plurality of light emitting diodes 1021 to emit light sources, the light sources emitted by the plurality of light emitting diodes 1021 enter from the two light inlet surfaces 1121 of the two light source guiding protrusions 112 of each curved light guiding element 11, the light sources entering from the two light inlet surfaces 1121 are totally reflected and propagated (as shown by broken lines in the light guiding plate 111 in the figure) in the light guiding plate 111 along the length direction of the light guiding plate 111, or the light sources in the light guiding plate 111 are refracted by the microstructure of the first light guiding surface 111a or the second light guiding surface 111b or the scattering particles in the light guiding plate 111 and emit light from the first light guiding surface 111a or the second light guiding surface 111b, so that the light guiding plate 111 emits light uniformly. The distance between the first light guiding surface 111a and the second light guiding surface 111b in the middle of the light guiding plate 111 in this embodiment is larger than the distance between the first light guiding surface 111a and the second light guiding surface 111b at two ends of the light guiding plate 111, that is, the two ends of the light guiding plate 111 are narrower, the middle is wider, which means that the light incident portion of the curved light guiding element 11 is narrower, so that most of the light sources can enter the curved light guiding element 11. In this embodiment, only one light source module 102 is optionally disposed, so that light enters from one of the two light source guiding protrusions 112 of each curved light guiding element 11, and the light sources can propagate in the light guiding plate 111 as well, so that the light guiding plate 111 emits light.

When the light source enters from the light entrance surface 1121, the light shielding layer 1122 is located in the light source propagation direction, so that the light source propagates to the surface of the light shielding layer 1122, and the light shielding layer 1122 reflects the light source, changes the light source propagation direction, and propagates along the light guide plate 111.
Further, the light incident surface 1121 is lower than the first light guiding surface 111a of the corresponding light guiding plate 111, in other words, a space is provided between the light incident surface 1121 and the corresponding first light guiding surface 111a, as shown in fig. 4, the space can accommodate the plurality of light emitting diodes 1021 arranged in a row, so as to prevent the plurality of light emitting diodes 1021 from being exposed, and effectively prevent the light sources emitted by the plurality of light emitting diodes 1021 from being emitted outside the curved light guiding element 11, and the light sources of the plurality of light emitting diodes 1021 can all enter the curved light guiding element 11. If the light incident surface 1121 is opposite to the first light guiding surface 111a, that is, the light incident surface 1121 is located at the inner side of the curved light guiding element 11, a space is provided between the light incident surface 1121 and the corresponding second light guiding surface 111b, and the space has the same function as the space, which is not described herein.
Further, each curved light guiding element 11 has four positioning protrusions 113, two positioning protrusions 113 are disposed at one end of the light guiding plate 111, another two positioning protrusions 113 are disposed at the other end of the light guiding plate 111, and the four positioning protrusions 113 protrude outwards from two opposite sidewalls of the light guiding plate 111. The light source supply assembly 10 further includes two positioning assemblies 103, where the two positioning assemblies 103 are respectively disposed in two second accommodating areas 1012 of the fixing base 101, and each positioning assembly 103 covers four positioning protrusions 113 of each curved light guiding element 11 to prevent the two curved light guiding elements 11 from being separated from the fixing base 101. In this embodiment, each positioning component 103 includes a first positioning component 1031 and a second positioning component 1032, the first positioning component 1031 is placed into the corresponding second receiving area 1012 from the first fixing opening 1010a of the fixing base 101, and the second positioning component 1032 is placed into the corresponding second receiving area 1012 from the second fixing opening 1010 of the fixing base 101 and is fixed to the first positioning component 1031, so that the positioning component 103 is fixed on the fixing base 101. In addition, the second housing 101b of the fixing base 101 has a through slot 1014, and the through slot 1014 is located between the two first accommodating areas 1011, so that heat energy generated by the two light source modules 102 located in the two first accommodating areas 1011 is dissipated from the through slot 1014, thereby effectively improving the heat dissipation effect of the lighting device 1.
