Problems solved by technology

[0003] Since the passive reflective device does not require additional power connection, it is often used outdoors. However, when the surface of the passive reflective device is covered with water droplets due to rain or stagnant water, its reflective effect will be greatly reduced
Take the passive reflective device used as road guidance as an example, when the reflective effect is reduced, it will lead to traffic safety problems

Embodiment Construction

[0041] The following will clearly illustrate the spirit of the present invention with drawings and detailed descriptions. Anyone with ordinary knowledge in the technical field can change and modify the technology taught by the present invention after understanding the preferred embodiments of the present invention. without departing from the spirit and scope of the present invention.

[0042] The structure adopted by the known reflective sheet can return the incident light along the parallel incident direction. However, when the surface of the known reflective sheet structure is covered by water droplets, the originally designed light return route is changed due to the different refractive indices of water and air. , the reflected light cannot be re-reflected as the expected parallel incident light, and the reflective ability is greatly weakened. Therefore, in order to perform retro-reflection regardless of whether there is water covering the surface of the reflective sheet, t...

Abstract

The invention provides a reflection structure, which comprises a substrate, a pattern layer, a composite glass bead layer and a fixing layer, wherein the pattern layer is arranged on the substrate; the composite glass bead layer is arranged on the pattern layer; and the composite glass bead layer comprises a first glass bead and a second glass bead. The second glass bead has a refractive index different from the first glass bead. The fixing layer is arranged on the pattern layer, a gap between the first glass bead and the second glass bead is filled, and the composite glass bead layer is fixed on the pattern layer through the fixing layer.

Description

technical field [0001] The present invention relates to a reflective structure, in particular to a reflective structure with high reflective ability. Background technique [0002] Common passive reflective devices include traffic signs, road guidance, raincoats and reflective sheets for vehicles. The general principle of these passive reflective devices is that a reflective material is provided in the device. After the light is irradiated on the reflective material in the device, the light reflection direction is designed. Through the guidance of the reflective material, the device can pass through the designed reflective route. glow. [0003] Since the passive reflective device does not require additional power connection, it is often used outdoors. However, when the surface of the passive reflective device is covered with water droplets due to rain or stagnant water, its reflective effect will be greatly reduced. Take passive reflective devices used as road guidance as a...
