The utility model relates to a public utility, more specifically to an adjustable self luminous public bus stop board. Board plates are fixedly arranged in two outer films. One small board plate is corresponding to one line, and the board plates made of luminous materials are in a related joint. Compared with the existing public bus stop board, the utility model has obvious characteristics. One small board plate is corresponding to one line. After all the small board plates are assembled into a large board plate, the large board plate is arranged in the outer films. Then, the large board plate is fixed through rivets. When one of the lines is replaced, a user opens the outer films and takes out a small board plate which needs to be replaced for placement. Integral replacement is not needed, which saves cost. The utility model can emit light for 12 hours after absorbing light for 10 minutes. At night or in dark light, passengers can conveniently see the utility model. The utility model is convenient to make, and the shape of the utility model can be made into an arbitrary shape according to design. Thus, the utility model can not be maliciously scratched easily or naturally eroded so that the utility model is durable.
