Matte Black Acrylic Wedge Lightbox with LED Lettering
A triangular-profile acrylic sign box combines a matte black face with light-diffusing polycarbonate and internal LEDs, showing white and yellow illuminated lettering.
This matte black acrylic lightbox has a triangular side profile and illuminated letter openings in its front face. The acrylic parts are CNC and laser cut, with light-diffusing polycarbonate (PC) and LEDs positioned behind the lettering. White and yellow light appear on the same front panel.
Cut Acrylic Face with Polycarbonate Diffusion
The main photograph shows the front and upper panel of the wedge-shaped box. Different letter sizes are cut into the black face, while the surrounding acrylic remains opaque and matte. PC diffusion panels and LEDs sit behind the openings to create the illuminated text. The plain black surfaces define the box around the lettering. This construction provides depth for a sign intended to project from a wall near an entrance or along a corridor. For another arrangement using black faces and illuminated letter sides, see the side-lit LED letter sign.

Triangular Side and Front Panel Connection
The detail photograph shows the lightbox turned to reveal its triangular side. The plain matte black side meets the illuminated front along a straight edge, showing the depth of the box. White and yellow letter openings remain visible from this angle. The photograph documents how the cut acrylic panels form the triangular-profile enclosure around the lighting.
