Abstract

The invention discloses an LED lamp device. The LED lamp device comprises a modulator tube, a light source device arranged on the modulator tube, and a cable connected with the light source device. The light source device is arranged at the top end of the modulator tube. Light emitted by the light source device is emitted to a target face through a shadow transmission and scattering device on the modulator tube and illuminates the target face, and a shadow pattern is formed on the target face. An elastic pipe fitting which is in a stretched state and extends in the axial direction of the modulator tube is arranged in the modulator tube. The cable penetrates through the elastic pipe fitting from bottom to top to be connected with the light source device. The LED lamp device is simple in structure and easy to manufacture, and when the LED lamp device is used, the produced shallow pattern can be clear and integral, and the boundary is not vague; meanwhile, the enough illumination degree is ensured for the face where the shadow pattern is formed, and people can feel that light rays are soft and comfortable.
