Abstract
A lighting effect device is provided, which is used for equipment with an operation surface that has a reflective characteristic. The lighting effect device includes at least a light supply unit for forming a light layer above the operation surface. The light layer is not crossed with the operation surface, where at least part of light of the light layer forms a visible lighting effect around an operator after reflected by the operator entering the light layer. The device requires less light sources and no position detection, so that the device is inexpensive and reliable. At the same time, a dodging layer and/or a reflective layer improve lighting effect and provide user a better experience.
