ABSTRACT:
A construction member includes a square frame. The frame is formed of a front frame and a back frame. A plate is secured to the inner side of an edge of the front frame. A glass tube constituting a visually perceptible part in the form of a letter or a pattern is secured to the back surface of the plate by an adhesive consisting of thermosetting resin having self-extinguish property. An electrode tube is formed at one end of the glass tube and the other end thereof. The glass tube encloses inert gas such as neon gas. A printed layer is formed on one main surface of the plate as another visually perceptible part by silk printing method or the like. The frame accommodates a reflective panel formed of stainless steel plate by spacing the reflective panel at a determined interval from the plate. A transformer for illuminating the glass tube is mounted on the back surface of the reflective panel.
