“OPEN”是使用 FontVibe AI 创作的激光切割文字效果。粗壮无衬线大写字母从暖色桦木上激光切出，切口边缘焦黑、木纹清晰，凸立在深色胡桃木板上，琥珀色侧光。

Frosted or clear acrylic material: letter faces are smooth matte-frosted acrylic surface. Cut edges emit a continuous soft luminous halo — frosted acrylic glows white-blue-cool, clear acrylic creates prismatic edge-light along every kerf perimeter. With LED backlighting, edges are the brightest element. Minimal geometric bridge tabs on enclosed counters. The cut piece installed on a dark backing with backlight glowing behind. Clean product photography on near-black background: the frosted acrylic 'OPEN' sign displayed as a complete product — mounted on its dark backing panel with a thin USB power cable coiling neatly below. LED edge-glow active, soft white-blue halos along every cut edge. Studio lighting from slight upper-left angle. The sign as a commercial product ready to order and install.
