This utility model provides a fade-resistant 3D number plate for overhead power line towers, relating to the field of line number plates. The fade-resistant 3D number plate includes a mounting plate with multiple sets of through holes on its surface. These through holes form the information to be displayed on the mounting plate. Color bars are inserted into the through holes, protruding from the mounting plate and extending to its front. This fade-resistant 3D number plate for overhead power line towers, by setting multiple through holes in different positions to form the information to be displayed, and by placing color bars inside the through holes, displays the information through color contrast between the color bars and the mounting plate. Even if the color bars are worn away by wind and sand, exposing the internal material, the internal material remains the same color as the color bar itself, thus achieving a fade-resistant effect.

The application provides a multi-color LED chip and a manufacturing method thereof. A first reflection layer, a first type limiting layer, an active region, a second type limiting layer, a composite current spreading structure and an ohmic contact layer are sequentially stacked on a substrate surface. The composite current spreading structure comprises a current spreading bottom layer, a second reflection layer, a third reflection layer and a current spreading top layer which are sequentially stacked along a first direction. Light waves reflected by the first reflection layer, the second reflection layer and the third reflection layer are sequentially reduced to realize a multi-color three-dimensional display effect of a single LED chip. Based on this, the wavelength bands reflected from the bottom surface of the light-emitting epitaxial structure are gradually reduced, and the light-emitting epitaxial structure surface is effectively prevented from emitting light downward to the active region to reduce light loss, and the lateral current spreading of the light-emitting epitaxial structure surface can be realized.

The application discloses a color matching method and system based on an Ostwald full-color gamut color mixing model, belongs to the field of color matching theory, color model construction, and color design methods and application development technology in the textile field, and discloses the following technical scheme: taking actually obtained red, yellow, green, blue, the highest brightness gray and the lowest brightness gray as the basis, an Ostwald color solid that can be applied to actual industrial design is constructed, and the traditional 24 color phases are broken through, and the Ostwald color solid can be flexibly applied to different color design scenes; in addition, in the grid model of the Ostwald color solid, the grid point position corresponding to each color is directly related to the mixing concentration ratio of black, white and pure color pigments required for matching the color, so that a designer can directly obtain the proportion of each pigment from the model to obtain a target color when matching colors, and therefore, the design efficiency is greatly improved.

This application proposes an ambient light with controlled three-dimensional color zoning, comprising: a substrate; a light-emitting unit mounted on the substrate, the light-emitting unit including a first light source and a second light source; a beam-splitting unit mounted on the light-emitting unit, configured to give the two light sources in the light-emitting unit different beam angles, wherein the beam angle of the first light source is smaller than that of the second light source; and a diffuser cover fitted over the substrate, forming a sealed space with the substrate, within which the light-emitting unit and the beam-splitting unit are placed. This allows for multiple combinations of emitted colors, uniformly emitting multicolored light on the same lamp, creating a three-dimensional effect, and is easy to install and low in cost.

To obtain a crustal deformation stereoscopic image processing system that can accurately color-code images based on elevation differences that take into account vertical and horizontal components, even when crustal deformation causes displacement in both vertical and horizontal directions. [Solution] A red stereoscopic map Gbi (image) is generated based on a new DEM of a predetermined area (S12), and a grayscale red stereoscopic map GBgi is generated (S16). On the other hand, the new DEM (post-earthquake) and the pre-earthquake (old) DEM (old DEM) are differentiated (simple difference) to highlight the areas of change (S24). Then, these areas of change are color-coded according to the degree of subsidence and uplift (S26).
