Specifically, the light source of the light source module may include any one or a combination of the following: a first light source 61 with a fixed band range and a second light source 62 with a variable band range.

When the light source module is a first light source 61 with a fixed band range, the specific form of the first light source 61 may be a white light source; of course, the first light source 61 is not limited to the above example, and in the embodiment of the present application, the first light source 61 is exemplified as a white light source, and other forms of the first light source 61 may be referred to herein, which will not be described herein.

When the light source module is a second light source 62 with a variable band, the second light source 62 is at least a second light source 62 including two channels. The second light source 62 is switchable between sub-bands of at least two different band ranges, for example the second light source 62 is switchable between a first band and a second band. The photonic crystal film 3 is provided with regions corresponding to the sub-bands, and different regions are used to reflect visible light of the corresponding sub-band ranges. For example, at least one region of the photonic crystal film 3 is used for reflecting the visible light of the first wavelength band, and at least another region is used for reflecting the visible light of the second wavelength band.

Further, the second light source 62 may be in the specific form of an RGB light source and a medium for interfering and diffracting light emitted from the RGB light source; alternatively, the second light source 62 is a combination of light sources having different wavelength ranges, for example, the second light source 62 may include a combination of one light source having a wavelength range in a first wavelength range and another light source having a wavelength range in a second wavelength range. Of course, the second light source 62 is not limited to the above example, and in one embodiment of the present application, the second light source 62 is exemplified by an RGB light source and a medium for interfering and diffracting light emitted by the RGB light source, and other forms of the second light source 62 may be referred to herein, which is not described herein. The medium for interfering and diffracting the light emitted by the RGB light source may specifically be a medium provided with an optical pattern, such as an injection molding member. The medium can change the light transmission mode by using the arranged optical patterns, so that the light is interfered and diffracted, and the wavelength of the light is changed.

In one embodiment, the light source module may include a light source and a light guide. The light guide piece is arranged on the light path of the light source. The light source may be the first light source 61 with a fixed wavelength range or the second light source 62 with a variable wavelength range. The light guide member is arranged on the light path of the light source and is used for uniformly guiding the light rays emitted by the light source to the photonic crystal membrane 3 to form an optical pattern.

In general, the photonic crystal film 3 may have the same size as the entire optical glass assembly, thereby facilitating processing and fabrication. The photonic crystal film 3 is provided at a central portion thereof with a predetermined region for forming an optical pattern. The predetermined area may be rectangular, circular, or other shapes, and is not specifically limited herein. In the embodiment of the present application, the predetermined area is described by taking a rectangle as an example, and other shapes can be analogically referred to the rectangle.

On the photonic crystal film 3, the predetermined area may be used as a reference for setting the light source and the light guide, and the specific position of the predetermined area may be adaptively adjusted according to the actual situation, and there may be no clear boundary profile on the optical glass component.

In one embodiment, the photonic crystal film 3 has a predetermined area for forming an optical pattern, the predetermined area including a first side 91 and a second side 92 opposite to each other, a third side 93 and a fourth side 94, and the light sources are distributed along at least one of the first side 91, the second side 92, the third side 93 and the fourth side 94.

As shown in fig. 2, in the present embodiment, the light source may include a group, and the group of light sources may include a plurality of light sources, and the plurality of light sources may be arranged at intervals along a certain side. The light source may also comprise multiple groups.

In a specific embodiment, as shown in fig. 3, the light sources may comprise two sets of light sources arranged opposite along a first side 91 and a second side 92 of the predetermined area or along a third side 93 and a fourth side 94 of the predetermined area.

Because the light emitted by the light sources is transmitted along a straight line, when two groups of light sources are arranged in a pair-by-pair mode along opposite sides, the brightness uniformity of the light on the light path where the two light sources are located can be ensured, and therefore the uniform presentation of the optical patterns can be ensured.

As shown in fig. 4, or in another specific embodiment, the light sources may be arranged simultaneously along the first side 91, the second side 92, the third side 93 and the fourth side 94, the light sources arranged along the first side 91 and the second side 92 being different from the wavelength ranges of the light sources arranged along the third side 93 and the fourth side 94.

When one light source having a first wavelength range is disposed along the opposite first side 91 and second side 92, and the other light source having a second wavelength range is disposed along the opposite third side 93 and fourth side 94, switching is performed by using two different light sources, so that not only the same light source can be used to illuminate a predetermined area of the photonic crystal film 3, but also a two-color or even multi-color light emitting color effect can be achieved; and the predetermined area of the photonic crystal membrane 3 can be irradiated by different light sources to exhibit different pattern switching effects.

Further, the light guide member is a light guide glass strip 7 with a predetermined size, and the light guide glass strip 7 is arranged on one side of the inner glass plate 5 away from the predetermined area.

When the light guide member is a light guide glass bar 7 having a predetermined size, the light guide glass bar 7 can effectively reduce the weight of the optical glass assembly and reduce the cost of the optical glass assembly with respect to the entire light guide glass plate.

Specifically, the light guiding glass strip 7 may be integrally formed into a strip shape, and the length dimension of the light guiding glass strip 7 is mainly based on the size of the optical pattern, so as to ensure that all positions of the optical pattern can receive light. Specifically, the dimensions of the light guide glass are not specifically limited herein.

Referring to fig. 3 or 6, in some embodiments, the light source module may include a plurality of light sources disposed along the first side 91 and the second side 92 or along the third side 93 and the fourth side 94, and the plurality of light sources are spaced apart on each side, and the light guiding glass strip 7 is located between the light sources and the edge of the optical pattern.

The light source modules may be arranged along opposite sides.

As shown in fig. 3, the light source modules are arranged along the first side 91 and the second side 92, so as to ensure that light can be uniformly guided into a predetermined area on the crystal film, where the nanoscale micro-physical structure is arranged; alternatively, as shown in fig. 6, the light source modules are arranged along the third side 93 and the fourth side 94, so that the light can be uniformly guided into the predetermined area of the crystal film provided with the nano-scale micro-physical structure.

The light guiding glass strip 7 is located between the light source and the edge of the optical pattern, in theory, the better the light guiding glass strip 7 propagates to the optical pattern from the optical pattern, the better the brightness and uniformity of the optical pattern, and the light guiding glass strip 7 can be 20 mm to 30 mm from the optical pattern in consideration of the comprehensive factors such as actual processing and manufacturing errors.

The photonic crystal film 3 may be made of an optical grade material capable of transmitting light, including but not limited to any one of the following materials: polyethylene terephthalate (Polyethylene terephthalate), polycarbonate (PC).

Of course, the specific materials of the photonic crystal film 3 may be other manners, and are not limited to the above description, and those skilled in the art may make other modifications in light of the technical spirit of the present application, but all the functions and effects implemented by the photonic crystal film are included in the protection scope of the present application as long as they are the same or similar to the present application.

The photonic crystal membrane 3 is provided with a nanoscale micro-physical structure in a nano imprinting mode.

Nanoimprinting is the most common method of processing polymer structures by patterning complex nanostructure structures on a stamp using high resolution electron beams, etc., and then deforming the polymer material with a pre-patterned stamp to form a structured pattern on the polymer. The nanoimprint technology is a low-cost and fast method for obtaining replicated structures on the nanoscale, which can repeatedly prepare nanopattern structures on a large area in large quantities, and the prepared high-resolution patterns have quite good uniformity and repeatability.

Specifically, the nanoscale micro-optical physical structure comprises: at least two physical structures with different refractive indexes and arranged periodically.

At least two different regions can be arranged in the photonic crystal membrane 3 in a nanoimprint manner, and each region is formed with a different nanoscale micro-physical structure, so that the wavelength of light acceptable by each region is within a specific wavelength range.

Referring to fig. 1, 2, 3 and 4, in a specific embodiment, the light source is a white light source, the wavelength range of the white light source is 400nm to 760nm, the wavelength range of the white light source is divided into at least two sub-wavelength bands, the photonic crystal film 3 is provided with a region corresponding to the sub-wavelength band, and different regions are used for reflecting visible light of the corresponding sub-wavelength band. Each different area on the photonic crystal film 3 may correspond to a sub-band of the light source one by one, or may correspond to a plurality of different areas, specifically, it may be adapted according to an actual pattern display requirement, etc., which is not limited herein.

Taking this photonic crystal film 3 as an example, seven regions are provided.

Specifically, the photonic crystal film 3 is provided with: a first region 81, a second region 82, a third region 83, a fourth region 84, a fifth region 85, a sixth region 86, and a seventh region 87, the first region 81 for realizing physical structural colors of 400nm to 430nm visible light reception, the second region 82 for realizing physical structural colors of 430nm to 450nm visible light reception, the third region 83 for realizing physical structural colors of 450nm to 500nm visible light reception, the fourth region 84 for realizing physical structural colors of 500nm to 570nm visible light reception, the fifth region 85 for realizing physical structural colors of 570nm to 600nm visible light reception, the sixth region 86 for realizing physical structural colors of 600nm to 630nm visible light reception, and the seventh region 87 for realizing physical structural colors of 630nm to 760nm visible light reception; the first, second, third, fourth, fifth, sixth and seventh regions 81, 82, 83, 84, 85, 86 and 87 can form a collocation of 823543 different colored patterns.

When the glass atmosphere lamp is manufactured, taking the section of fig. 1 as an example: the optical crystal film is added to the outer glass plate 1 and the first bonding layer 2, the second bonding layer 4 is covered again, finally, the inner glass plate 5 is overlapped to form an optical glass assembly by glass lamination, meanwhile, the light guide glass strip 7 is bonded to the fourth surface of the inner glass plate 5, and a white light source is arranged on one side of the light guide glass strip 7, which is far away from the optical pattern.

As shown in fig. 2, the design of a specific zone imprint is schematically as follows: the first area 81 realizes the physical structural color (purple) of 400-430 nm visible light reception, the second area 82 realizes the physical structural color (blue) of 430-450 nm visible light reception, the third area 83 realizes the physical structural color (cyan) of 450-500 nm visible light reception, the fourth area 84 realizes the physical structural color (green) of 500-570 nm visible light reception, the fifth area 85 realizes the physical structural color (yellow) of 570-600 nm visible light reception, the sixth area 86 realizes the physical structural color (orange) of 600-630 nm visible light reception, the seventh area 87 realizes the physical structural color (red) of 630-760 nm visible light reception, the areas can realize the collocation of the color patterns of 823543 colors to 7 times of random combination 7, and simultaneously can combine the target color patterns designed by different pattern combination modes of the size and the shape of each area to realize the multicolor luminous color effect of the same light source luminous pattern.

Of course, the band division of the white light source is not limited to the above example, and it may be further divided for the same physical structural color of visible light, for example, in the case of the purple color, it may be further divided into: 400 nm-410 nm light violet, 410 nm-420 nm violet, 420 nm-430 nm deep violet, etc. Correspondingly, the areas on the photonic crystal film 3 can be provided with different color areas according to the requirements of the actual pattern luminescent colors.

Referring to fig. 5 and 6, in another specific embodiment, the second light source includes at least two switchable light sources: at least one region of the photonic crystal film 3 is used for reflecting the visible light of the first wave band, and at least one other region is used for reflecting the visible light of the second wave band.

In this embodiment, the second light source may include at least two switchable band ranges, i.e. a first band and a second band, and of course, more bands may be set according to the switching requirement of the actual pattern. The first light source may be a light source whose own wavelength band can be switched, or may be a combination of two or more light sources whose wavelength bands are different, or may be a combination of a light source including a plurality of groups of fixed wavelength bands and a medium capable of adjusting the wavelength range.

At least one region of the photonic crystal film 3 is used for reflecting the visible light of the first wave band, and at least one other region is used for reflecting the visible light of the second wave band. Taking the example that the second light source comprises a first wave band and a second wave band which can be switched, wherein one area can be used for reflecting the visible light of the first wave band, and two or more areas can be used for reflecting the visible light of the first wave band; likewise, one region may be utilized to reflect the second band of visible light, or two or more regions may be utilized to reflect the second band of visible light. The division of the specific area and the corresponding relation between different wave bands and the area can be adaptively adjusted according to the requirements of the design pattern, and the application is not particularly limited herein.

For example, the second light source may be a combination of an RGB light source and a medium for interfering and diffracting light emitted from the RGB light source, where a wavelength range of the second light source can be within: the photonic crystal membrane is provided with N areas, and the N areas correspondingly reflect visible light of the first wave band, the second wave band and the third wave band, wherein N is a positive integer greater than or equal to 2.

For example, the photonic crystal film 3 is provided with a first region 81 for realizing a physical structural color of visible light reception in a first wavelength range and a second region 82 for realizing a physical structural color of visible light reception in a second wavelength range.

When the RGB light source is switched between the light source of the first color corresponding to the first wavelength range and the light source of the second color corresponding to the second wavelength range through a medium, the preset pattern on the glass atmosphere lamp can be switched.

When the glass atmosphere lamp is manufactured, taking a section of fig. 5 as an example: the outer glass plate 1 is added with the first bonding layer 2, then an optical crystal film is added, the second bonding layer 4 is covered again, finally, the inner glass plate 5 is overlapped, glass is combined to form an optical glass assembly, meanwhile, the fourth surface of the inner glass plate 5 is bonded with the light guide glass strip 7, and an RGB light source is arranged on one side of the light guide glass strip 7, which is far away from the optical pattern. The medium may be fixed to the light guide glass strip 7 by bonding or the like, that is, the medium, the light guide glass strip 7, and the inner glass plate 5 are sequentially disposed.

The RGB light sources can be combined on the peripheral side surfaces of the films in a random and pairwise mode, light rays are led into the special films subjected to the partition imprinting, needed color light is led out to form a specific optical pattern combination, and the light emitting patterns are switched by controlling the colors of the light sources.

As shown in fig. 6, the design of a specific zone imprint is illustrated: the first area 81 is used for fixedly dividing a physical structural color (purple) of 400-430 nm visible light reception into one area to form a pattern, the second area 82 is used for fixedly dividing a physical structural color (blue) of 430-450 nm visible light reception into two areas to form another different pattern, and the pattern switching can be realized by switching an R.G.B light source between the purple and blue light sources, for example, when the R.G.B light source emits purple light, the first area presents a pattern of a wine glass, and the second area is not bright; when the R.G.B light source emits blue light, the second area presents two opposite face patterns, and the first area is not bright.

The above fig. 6 is only a simple example, and the pattern switching effect can be realized by switching a specific color of the r.g.b light source by using a plurality of partition patterns and a plurality of structural colors according to design requirements.
