Abstract:
An LED transparent brick comprises a transparent brick body, a photo catalyst layer, a connecting layer, a light reflection layer and one or more ultraviolet LEDs. The photo catalyst layer is placed at a first surface of the transparent brick body, and the connecting layer combines the transparent brick body and the photo catalyst layer. The light reflection layer is placed at a second surface of the transparent brick body, and the second surface corresponds to the first surface. The ultraviolet LED is placed at a side of the transparent brick body, and illuminates the photo catalyst layer to generate oxidative decomposition and hydrophilic capabilities. The light reflection layer can increase light reflection in the transparent brick body to the photo catalyst layer.
