When the LED lighting device is used, the reflective baffle 100 is connected to the first light diffusing assembly 300, and meanwhile, it is ensured that light emitted from the first light diffusing assembly 300 can be reflected by the reflective baffle 100. The reflective bezel 100 is then mounted to a corresponding support surface (e.g., a ceiling or a lighted wall). At this time, the LED lamp set 200 is located at an end of the first light expansion assembly 300 away from the reflective baffle 100, light emitted from the LED lamp set 200 cannot be directly reflected by the reflective baffle 100, but the light first enters the first light expansion assembly 300 to be reflected, scattered and the like, after the first light expansion assembly 300 expands light (i.e. the first light expansion assembly 300 is entirely bright, i.e. light expansion is completed), the light is emitted from the first light expansion assembly 300 and is reflected by the reflective baffle 100. Therefore, compared with the case that the LED lamp set 200 is directly connected to the reflective baffle 100, the LED lighting device can effectively reduce the ineffective reflection between the LED lamp set 200 and the reflective baffle 100 (the distance between the light emitting position of the LED lamp set 200 and the reflective baffle 100 is too short, and the included angle between a part of light and the reflective baffle 100 is too small, so that the light cannot irradiate the preset lighting area), i.e., the lighting effect of the LED lamp is improved.
