Embodiment Construction
[0018] Embodiments of the present invention will be described below with reference to the drawings.
[0019] figure 1 A cross-sectional view of a lighting device according to an embodiment of the present invention is shown. The light-emitting diode lighting device with gradually changing brightness according to the present invention includes a side wall reflector 1 , a light source part 2 and a light-emitting surface 4 . The side wall reflector 1 is connected to the light source part 2, and the light-emitting surface 4 is divided into a main light-emitting area 42 and an auxiliary light-emitting area 41. The main light-emitting area 42 and the auxiliary light-emitting area 41 are combined together obliquely, and the main light-emitting area 42 is illuminated by the light source part 2 , the auxiliary light emitting area 41 is indirectly illuminated by the reflected light passing through the side wall reflector 1 .
[0020] In this embodiment, the light-emitting surface 4 is ...
