Abstract: An optical touch sensing structure includes a transparent substrate and a plurality of optical particles with metallic composition. The optical particles with metallic composition are disposed on the transparent substrate. When an infrared is incident on each of the optical particles with metallic composition, the infrared is reflected by each of the optical particles with metallic composition.

Abstract: A reflective structure for optical touch sensing, which includes a transparent substrate, a plurality of microstructures and a transmittive reflective layer. The transparent substrate has a surface. The microstructures are disposed on the transparent substrate and expose a portion of the surface to allow a visible light to pass through. The transmittive reflective layer is disposed on the microstructures and at least covers a portion of the microstructures.

Abstract: An optical touch sensing structure includes a transparent substrate, a transparent adhesive layer and a plurality of transparent optical spheres. The transparent substrate has a top surface, and the transparent adhesive layer is disposed on the top surface of the transparent substrate. The transparent adhesive layer includes a plurality of adhesive portions. The adhesive portions are separate from one another and expose a portion of the top surface. The transparent optical spheres are disposed on the adhesive portions. The transparent optical spheres at each adhesive portion are arranged as a single layer, and the transparent optical spheres are fixed on the transparent substrate via the adhesive portions. When an infrared ray reaches each transparent optical sphere, the infrared ray is retroreflected and reflected by each transparent optical sphere.

Abstract: An optical touch sensing structure includes a transparent substrate and a stacked transparent optical layer. The transparent substrate has an upper surface. The stacked transparent optical layer is disposed on the upper surface of the transparent substrate with a portion of the upper surface being exposed. The stacked transparent optical layer is formed by stacking at least one first transparent optical layer and at least one second transparent optical layer. The refractive index of the first transparent optical layer is greater than the refractive index of the second transparent optical layer. The stacked transparent optical layer is adapted to allow a visible light to pass through and has a rough surface. When an infrared light is incident to the stacked transparent optical layer, the infrared light is reflected by the stacked transparent optical layer and scattered by the rough surface.

Abstract: The present invention provides a lighting device having an energy conversion module, comprising a lamp and at least one energy conversion module. The lamp includes a shade and a lamp tube. The lamp tube is disposed beneath the shade, and the inner wall surface of the shade can reflect light from the lamp tube. The energy conversion module is configured inside the shade or disposed on a lamp grid to receive light energy and convert it into electrical energy. As such, the lighting device can give light to photovoltaic cells in the environment so that electrical energy is generated. The object of converting part of the light energy into electrical energy for further utilization can thus be achieved.
