• the pattern of the luminous glass is usually based on enamel or ink to form a pattern area on the glass surface.
• incident light emitted by a light source arranged on the side or bottom of the glass or integrated in the glass is projected to the pattern area, the light is scattered or diffused to emerge through the pattern area due to the change of the surface structure, thus realizing the lighting effect of pattern luminescence.
• the existing luminous glass usually changes the pattern shape and lighting area to meet the requirements of the consumers, but the consumers still expect the pattern to bring more different feelings and experiences when the pattern is illuminated.
• the object of the present disclosure is to propose a luminous glass with pattern. Different regions of the pattern on the luminous glass can present different visual differences in both a non-illumination state and an illumination state, and such visual differences bring more unique spatial sense, which can not be achieved by a single pattern, thus enhancing the consumer experience.
• a luminous glass with pattern comprises a glass body and a pattern formed by a light extraction layer arranged on the glass body, wherein the light extraction layer is configured to meet that: in a non-illumination state, different regions of the pattern formed by the light extraction layer have different visibility; in an illumination state, different regions of the pattern formed by the light extraction layer have different brightness.

• the pattern with larger thickness size has higher visibility than the pattern with smaller thickness size
• the pattern with thicker line has higher visibility than the pattern with thinner line (smaller line width diameter)
• the thicker lines of the pattern are perceived by human eyes to be more visible to the observer, that is, the lines with different line width diameters formed by the same material appear different visibility.
• the "brightness” in this context is specific to the illumination state, and is usually determined by the refractive index of the material forming the pattern.
• the luminous intensity per unit area is the same, and the brightness presented by the pattern is related to the luminous intensity per unit area and the pattern area of the local region.
• the local region with a larger pattern area will make the brightness perceived by human eyes relatively high.
• the present disclosure also provides an illumination effect, that is, when the light source is turned off and in the non-illumination state, the pattern of the luminous glass has a spatial visual effect because different regions of the pattern formed by the light extraction layer have different visibility, and compared with the existing monotonous pattern, the luminous glass of the present disclosure brings different experiences to the consumers.
• the luminous glass can not only appear a spatial effect when displaying the required lighting pattern, but also obtain unpredictable and rich visual effects if the lighting effect (such as color, light intensity, dynamic effect, etc. ) generated by the light source is combined.

• a plurality of light extraction structures are feasible.
• different optical properties should be understood as including different visibility of different light extraction structures in the non-illumination state and different brightness in the illumination state under the same material or different materials conditions.
• the visibility and brightness of different light extraction structures with the same material can be different by changing the thickness size of the pattern formed by the light extraction structures and/or the line width diameter (line diameter) of the line form of the pattern, or the visibility and brightness can be different through different light extraction structures with different materials under the conditions of the same or different thickness size and/or the same or different line width diameter.

Due to the different enamel materials and different thickness sizes, the first light extraction structure and the second light extraction structure can present different visibility in the non-illumination state, and the visual difference is significant. In addition, due to the use of different enamel materials and different thickness sizes, the obtained pattern can also appear significantly different visual differences under the illumination state. The same is true for the line width diameter of pattern lines, which will not be described in detail below.
• the first light extraction structure adopts the enamel 1 with a first thickness size
• the second light extraction structure adopts the enamel 2 with the first thickness size. Due to the different enamel materials, the first light extraction structure and the second light extraction structure present different visibility in the non-illumination state, and the visual difference is significant.

• the use of different enamel materials can more easily allow the pattern to achieve significantly different light and shade effects under the condition of using the same or similar lines (for example, the thickness size or line diameter is the same or similar) , so that the overall luminous pattern is more layered.
• the glass body can be single-layer glass body or laminated glass.
• the first light extraction structure and the second light extraction structure may be arranged on the same surface of the single-layer glass body.
• the first light extraction structure and the second light extraction structure can also be arranged on the same surface of the functional layer or between the glass body and the functional layer.

• the thinner straight lines or polylines 210 are staggered with the thicker straight lines or polylines 220, and the thinner curved lines 230 and the thicker curved lines 240 are staggered, wherein the thinner lines are printed for example by the enamel 2, and the thicker lines are printed for example by the enamel 1.
• the final effect is as follows: under the non-illumination state, according to the different characteristics of the two enamels, the thicker lines with high visibility (the straight lines or polylines 220 and the curved lines 240) are perceived as closer from the observer's point of view, while the thinner lines with low visibility (the straight lines or polylines 210 and the curved lines 230) are perceived as further away, so that the observer can experience the pattern 200 with spatial visual effect and with different visibility in the non-illumination state.
• the thicker lines (the straight lines or polylines 220 and the curved lines 240) appear higher brightness, while the thinner lines (the straight lines or polylines 210 and the curved lines 230) appear lower brightness, which also brings the observer a pattern with spatial sense.
• the color of enamel material can also be changed according to different requirements, and is not limited to white commonly used.
• different enamels with different colors can achieve different display effects under the same lighting conditions.
• the light extraction layer constituting the pattern is configured to have different visibility and brightness in different regions of the pattern, so that the illumination effect is ensured, and at the same time, a spatial visual effect different from the conventional pattern is provided, and the consumer experience is significantly improved.
