Abstract
The utility model belongs to the field of automobile accessory design, and particularly relates to an evenly-lightened high-position brake lamp optical device which comprises a mask, a lens structure, a PCBA board and a shell. Wherein the lens structure enters the mask from the top surface, and the shape of the top surface of the lens structure is matched with the shape of the mask; a plurality of connecting columns are arranged on the bottom surface of the lens structure and are arranged in clamping grooves in the PCBA board; the PCBA board is fixedly arranged in the shell through screws; and the shell is welded with the mask to form a complete optical device. According to the utility model, the rectangular Fresnel lens is used for scattering up, down, left and right 5-degree light spots, so that the problem of black seam areas in traditional particle splicing is greatly eliminated on the mask.
