A lighting device directly radiates a light beam on a front face (79) of a label (74a), where the device is sufficiently powerful such that illumination produced by the device is greater than 30 lux. The call button has a window (88) arranged in an upper part of a side face (84) of the button. The lighting device is partially located inside the button facing the window, so that the light beam passes through the window. An independent claim is also included for an electrical door opener of house, comprising a label holder block.</p> |
