The invention discloses a positive light advertising board device, which comprises a light guide plate and an advertising board. At least one end face of the light guide plate is provided with a luminous source, the light guide plate is in gapless contact connection with the surface of the advertising board through a transparent salient point, the total reflection light in the light guide plate is guided to the front surface of the advertising board through the transparent salient point, and the position of the transparent salient point is at a light emission port in the light guide plate. The device is directly contacted with the advertising board in a mode of a light guide point, and can have multi-point precise selective illumination so as to reduce the loss of interface light, reduce the stray light, increase the white-black contrast, improve the optical efficiency and reduce the manufacturing and using costs. The advertising board is replaced by a common advertising board, and the device also can be used as an indoor common illumination lamp such as a desk lamp, a wall lamp and the like.
