The embodiment of the invention relates to the technical field of terminals, in particular to a luminous module support and a terminal device in order to solve the problems that metal supports are ineffectively grounded and radio frequency interference is caused by residual static electricity. The luminous module support is applied to the terminal device, and the terminal includes a middle frame and a containing space defined by the middle frame and a metal frame on the top of the terminal device; the luminous module support comprises a structural optical support body and at least two grounding loops. The structural optical support body is located in the containing space and used for fixing and protecting an active illuminating module located on the top of the terminal device, the structural optical support body is in contact with the middle frame through the grounding loops, and the grounding loops are used for guiding the static electricity generated on the structured optical supportbody to a grounding circuit of the middle frame.
