Also, the terminology used in this specification includes any and all combinations of the associated listed items.
In one embodiment, as shown in fig. 1, there is provided a starlight glass skylight, which includes a skylight glass 110, a directional reflection film 120 and two or more light sources 130, wherein the directional reflection film 120 is disposed in the skylight glass 110, each light source 130 is disposed in a different orientation of the skylight glass for emitting light to the directional reflection film 120 in the skylight glass 110, and the directional reflection film 120 forms a corresponding starlight scene according to the reflection of the light emitted by each light source 130.
Specifically, the shape of the sunroof glass 110 is not exclusive and may be a polygon, a circle, an ellipse, or the like. The light source 130 is provided in a different manner depending on the shape of the sunroof glass 110. For example, when the sunroof glass 110 has a polygonal shape, the light source 130 may be disposed at a part or all of the side edges of the sunroof glass 110; when the skylight glass 110 has a circular or oval shape, the light source 130 may be disposed around the skylight glass 110. The color of the light emitted from each light source 130 may be the same or different, and after the light emitted from the light sources in different directions reaches the directional reflective film 120, the star landscape displayed through the skylight glass 110 after being reflected by the directional reflective film 120 is correspondingly different.
Specifically, taking the skylight 110 as a quadrangle as an example, the light sources 130 disposed on the same side of the skylight 110 may be used as a group of light sources, the light color emitted by the same group of light sources is the same, and each group of light sources may be independently controlled to be turned on and off. When a user controls one of the light sources to turn on, the directional reflection film 120 performs directional reflection on the light of the light source to form a corresponding star spot. The formation of the star spot by the directional reflection of the directional reflection film 120 may also change after the user controls the other set of light sources to be turned on. The star-sky scenes projected by different groups of light sources can be partially or completely changed in pattern shape, pattern color, display position and size. It is understood that in other embodiments, only one light source 130 may be disposed on each side of the skylight 110, and the switching between different starry sky scenes may be realized by individually controlling the on and off of each light source 130.
The light source 130 may be a collimated light source or a point light source, and in one embodiment, as shown in fig. 2, the light source 130 is a collimated light source, further ensuring the brightness of the light spot. The parallel light source can adopt a laser array, or consists of a point light source matched with devices such as a lens and the like, and the specific structure is not described in detail.
In the starlight glass skylight, the light sources 130 arranged at different directions of the skylight glass 110 emit light to the directional reflection film 120 in the skylight glass 110, so that the directional reflection film 120 reflects the light emitted by each light source 130 to form a corresponding starry sky scene. The switching of the starry sky sceneries can be performed by controlling the light sources 130 in different directions to emit light, so that the dynamic display of the starry sky sceneries is realized, and the use by a user is facilitated. The light source 130 is used for emitting light to enable the directional reflection film 120 to reflect and transmit through the skylight glass 110 to generate a starry sky picture, so that the light spot brightness can be well ensured, and the use reliability is improved.
The skylight 110 may be a single-layer or multi-layer structure, and in one embodiment, as shown in fig. 3, the skylight 110 includes an outer pane 111 and an inner pane 112, and the directional reflection film 120 is located between the outer pane 111 and the inner pane 112. Specifically, a sunroof opening may be formed in the top of the vehicle for installing the skylight glass 110, the outer side glass 111 is a glass layer facing the outside of the vehicle, the inner side glass 112 is a glass layer facing the inside of the vehicle, the skylight glass 110 is designed by using a double-layer glass structure, and the directional reflection film 120 is designed between the double-layer glass.
Further, in one embodiment, the skylight glass 110 further includes an adhesive layer 113, the adhesive layer 113 is located between the outside glass 111 and the inside glass 112, and the directional reflection film 120 is disposed on the adhesive layer 113. The adhesive layer 113 may specifically be a PVB (Polyvinyl Butyral) layer. The outer glass 111 and the inner glass 112 are bonded by the adhesive layer 113, thereby improving the reliability of the sunroof glass 110. The adhesive layer 113 may also be a single-layer or multi-layer structure, in this embodiment, the adhesive layer 113 includes two layers, and the directional reflection film 120 is located between the two adhesive layers 113, and may also function to protect the directional reflection film 120.
The specific configuration of the directionally reflective film 120 is also not exclusive, and in one embodiment, the directionally reflective film 120 comprises a transparent substrate provided with directionally reflective regions corresponding to the respective light sources. Specifically, the transparent substrate may be a transparent material selected from PC (Polycarbonate), PMMA (polymethyl methacrylate), and the like. The directional reflection diaphragm 120 may be a single piece or a plurality of pieces stacked. Taking a single directional reflection film 120 as an example, a plurality of directional reflection regions may be formed on a transparent substrate of the directional reflection film 120 by etching/die-etching, each directional reflection region being a star spot region corresponding to one directional light source 130, and the pattern shape, size, and position of the star spot formed by the light reflected by each directional reflection region are different from each other. When the light sources 130 in different directions are controlled to be turned on in sequence, the displayed starlight patterns can be switched among a plurality of dynamic patterns, and the dynamic effects of starlight flickering, moving and rotating can be realized through continuous pattern switching.
Further, in one embodiment, the directionally reflective membrane 120 further includes a metallic semi-permeable membrane disposed in the directionally reflective region. Specifically, the metal semi-permeable film with different thicknesses can be plated in each directional reflection area of the transparent base material, so that the reflectivity of each directional reflection area is adjusted, and the condition that the star light around the skylight is bright and the star light in the middle area is dark due to light attenuation is avoided.
It is understood that the color and power of the light sources 130 in different orientations can be adjusted according to the actual situation, and the light sources 130 can be disposed on part or all of the side edges of the skylight 110. In one embodiment, taking the skylight 110 as a quadrangle, the light sources 130 in different orientations have different colors, and/or the light sources 130 are sequentially disposed around the skylight 110. Specifically, a set of parallel light sources may be respectively disposed on four sides of the skylight glass 110, and the colors of the parallel light sources in each set are different from each other, so as to facilitate the distinction. As shown in fig. 2, a red collimated light source, a purple collimated light source, a yellow collimated light source, and a blue collimated light source may be provided on the four sides of the sunroof glass 110, respectively. If the parallel light source of one color is controlled to be turned on, the starlight pattern of the color can be formed after being reflected by the corresponding directional reflection area on the directional reflection film 120, and the starlight patterns of different colors and shapes can be obtained by sequentially switching the parallel light sources of different colors to be turned on, so that the dynamic switching of different starlight patterns is realized. As shown in fig. 4, taking the blue parallel light source as an example, after the blue parallel light source is controlled to be turned on, an observer in the vehicle sees a blue starlight pattern formed by the blue incident parallel light reflected by the corresponding directional reflection region on the directional reflection film 120 and the generated blue reflected parallel light.
It should be noted that the specific shape of the starlight pattern corresponding to the parallel light source of each color can be adjusted according to actual needs. For example, each color of parallel light source can be a single starlight spot obtained by reflecting light through the corresponding directional reflection region, the single starlight spots formed by the parallel light sources of different colors can be hollow pentagons, solid pentagons, large dots or small dots, and the like, and the position of each starlight spot is different, so that switching among several stargrams is realized; or, the parallel light source of each color may be a pattern composed of a plurality of starlight spots obtained after the light is reflected by the corresponding directional reflection region, and the type, number and mutual distance of the starlight spots are not changed, but only the overall display position of the pattern generated by the parallel light sources of different colors is changed, so as to realize the dithering and flicker of the star map; or, the parallel light source of each color may be a pattern composed of a plurality of star spots obtained by reflecting light through the corresponding directional reflection region, and the type, number and mutual distance of the star spots are also kept unchanged, but the overall display angle of the pattern generated by the parallel light sources of different colors is changed, thereby realizing the rotation of the star map. In addition, in other embodiments, the collimated light source of each color may also be a pattern composed of a plurality of starlight spots obtained by reflecting light through the corresponding directional reflection region, and the overall display position and angle of the pattern and the positional relationship between the starlight spots in the pattern are all changed.
It is understood that in other embodiments, the parallel light sources in different orientations may use the same color, and thus, when different parallel light sources are switched on, the position and shape of the pattern may also be changed.
In one embodiment, the skylight further includes a compass and a controller, the controller connecting the compass and the light source 130; the controller determines the vehicle orientation according to the compass signal sent by the compass and controls the corresponding light source 130 to work according to the vehicle orientation, so that the directional reflection film 120 displays the starry sky scene corresponding to the vehicle orientation. The compass may be an existing vehicle-mounted system compass of the vehicle, and the controller may be an ECU (Electronic Control Unit), an MCU (Micro Control Unit), or other Control modules. Specifically, different directional reflection regions of the directional reflection film 120 may be designed in advance, so that a starry sky scene formed by light emitted from each directional reflection region corresponds to different vehicle orientations of the vehicle, for example, when the vehicle is in different orientations, the relative position of each starlight spot in the starry sky scene is kept unchanged, and only the overall display angle of the starry sky scene is changed. Similarly, taking the parallel light sources as an example, the directions of the vehicles, the starry sky scenes of each directional reflection area and the corresponding relations of the parallel light sources of each color are bound and stored in the controller, and in the driving process of the vehicles, the controller controls the parallel light sources of the corresponding colors to be turned on according to the directions of the vehicles detected by the compass, so that the starry sky scenes corresponding to the current directions of the vehicles are formed after the lights of the colors are reflected by the directional reflection areas of the directional reflection film 120. After the vehicle direction changes, the corresponding starry sky scene can be automatically switched to, and the automatic rotation of the starry sky scene aiming at different vehicle directions is realized.
Further, the skylight glass can also comprise a processing switch connected with the controller. The processing switch is used for sending a control command to the controller so as to control the starry sky scene to be turned on and off and the display mode when the starry sky scene is turned on. Specifically, as shown in fig. 5, the processing switch may send a command to control on/off to the ECU, which turns off all the parallel light sources when receiving the off command. If the ECU receives the opening instruction, the display mode of the starry sky scene can be adjusted according to the type of the opening instruction.
The display mode may include a default mode and a compass mode, the default mode may be a random mode, a rotation mode or a blinking mode, correspondingly, the ECU may control the parallel light sources to be turned on according to a corresponding program in the default mode, and the control signal of each group of parallel light sources is generated by a random signal or executes a predetermined rotation and blinking control signal, independent of a compass signal x sent by the compass. The parallel light source is turned on or off according to the received control signal, so that the starry sky pattern is displayed randomly, or the starry sky cluster rotates and flickers. And when in the compass mode, the ECU controls the parallel light source to be started according to a corresponding program in the compass mode. The ECU obtains a parallel light source group signal f (x) according to the received compass signal x, and particularly, the selection can be judged in data matrixes x and f (x) by an IF/CASE method on software coding. The parallel light source group works according to the received signals f (x) to realize the switching between a plurality of groups of star maps in combination with the vehicle direction, for example, when the vehicle is in four different directions of south, east, west and north, the star sky maps in the south, west and north directions are respectively switched.
In one embodiment, the skylight further includes a photoelectric sensor disposed on the skylight glass, the photoelectric sensor is connected to the controller and is used for collecting the light difference between the inside and the outside of the skylight glass 110 and sending the light difference to the controller, and the controller controls the brightness of the light source 130 according to the light difference between the inside and the outside of the skylight glass 110. Specifically, as shown in fig. 3, the photosensor may include an outer photodiode 141 and an inner photodiode 142, the outer photodiode 141 being disposed within the adhesive layer 113 proximate to the outer glass 111, and the inner photodiode 142 being disposed within the adhesive layer 113 proximate to the inner glass 112. The outside photodiode 141 and the inside photodiode 142 generate a voltage difference according to the intensity of the light source outside the vehicle and the intensity of the light source inside the vehicle, and generate an inside-outside light intensity difference signal to be sent to the ECU. As shown in fig. 5, the positive and negative of the voltage difference respectively represent that the inner and outer layers are brighter, the absolute value of the voltage difference represents the relative ratio of the inner and outer brightness, and the ECU adjusts the power of the turned-on parallel light source according to the received inner and outer light intensity difference signal, thereby changing the brightness of the parallel light source.
In one embodiment, a vehicle is also provided, which comprises the starlight glass skylight.
In the vehicle, the light sources 130 arranged in different directions of the skylight glass 110 emit light to the directional reflection film 120 in the skylight glass 110, so that the directional reflection film 120 reflects the light emitted by each light source 130 to form a corresponding starry sky scene. The switching of the starry sky sceneries can be performed by controlling the light sources 130 in different directions to emit light, so that the dynamic display of the starry sky sceneries is realized, and the use by a user is facilitated. The light source 130 is used for emitting light to enable the directional reflection film 120 to reflect and transmit through the skylight glass 110 to generate a starry sky picture, so that the light spot brightness can be well ensured, and the use reliability is improved.
In order to facilitate a better understanding of the star glass skylight and the vehicle, the following detailed description is provided in connection with specific embodiments.
The existing starlight glass skylight roof has the starlight roof effect formed by inserting optical fibers into an interior ceiling, the starlight pattern is invariable, the inserting depth of the optical fiber type starlight roof is not easy to control, the light spot brightness is influenced, and the opaque roof has the starlight effect which is just a little difficult. Based on this, the purpose of this application is to provide a device that can present dynamic starlight effect, and the starlight pattern can switch between several kinds of dynamic patterns, and continuous pattern switching can realize the dynamic effect of starlight scintillation, removal, rotation, and the realization mode adopts directional reflection surface technique. In addition, the brightness of the starlight varies with the intensity of the background light.
Specifically, the directional reflective dynamic starlight glass skylight provided by the application has the following characteristics and requirements:
1. the LED lamp is provided with independent multiple groups of parallel light sources, each group of light sources can be independently controlled to be turned on and off, and each light source has an independent layout angle: i.e. at different orientations around the vehicle, each light source color may optionally be distinguished.
2. A directional reflecting film (integrated into the skylight glass) having at least one etched/patterned directional reflecting area (star spot area) respectively corresponding to each group of independent light sources, and optionally, such a directional reflecting film may be stacked in a plurality of sheets.
The above is a requirement, and the following requirements can be added as optional supplements: an ECU control module; the compass can be used as a vehicle-mounted system compass; a photoelectric sensor.

Each group of light sources can be independently controlled to be turned on and off. The higher the parallelism of the parallel light source is, the smaller the interference among different images is; or the larger the number of images that can be presented under the same degree of inter-image interference. The parallel light source can be provided by a laser array or a point light source matched with a lens and the like.
It should be noted that besides a parallel light source, a point light source can also achieve this effect. The smaller the light emitting radius of the point light source is, the smaller the interference between different images is; or the larger the number of images that can be presented under the same degree of inter-image interference. The advantage of the parallel light source is that, near the light source area, the disadvantage that the skylight glass partially glows is weak because the light source is weaker than the dispersed light intensity; the advantage of point light sources is that a relatively large number of individual point light sources can be arranged and a correspondingly large number of images can be realized. Both schemes are described to ensure the completeness of the technical scheme, but the detailed explanation is only given by taking a parallel light source as an example. Considering that skylight glass can not achieve 100% transparency and no impurities at present, the parallel light source scheme is adopted, and light spot brightness uniformity can be better guaranteed.
The directional reflection film is integrated on skylight glass, the base material is transparent materials such as PC/PMMA, laser etching or mould pressing repeated etching is carried out on a local starlight spot area to form a directional reflection area, and the directional reflection area is only limited to the starlight spot area. Furthermore, the reflectivity of the directional reflection area can be adjusted by plating metal semi-permeable film films with different thicknesses and other technologies, so that the problem that the star light around the skylight is brighter and the star light in the middle area is darker due to light attenuation is solved.
The ECU control module is connected with the processing switch and the photoelectric sensor, receives the compass signal and outputs a control signal to control the on and off of each group of light sources and the brightness of the light sources. The compass is used for judging the azimuth change of the vehicle so as to realize the dynamic effect of the movement of the scuttle and the star when the azimuth of the vehicle changes. The photoelectric sensor is used for judging the light intensity difference inside and outside the vehicle so as to adjust the brightness of the light source.
The directional reflection type dynamic starlight glass skylight can realize switching among a plurality of groups of star maps, and when a vehicle is in four different directions of south, east and west, the directional reflection type dynamic starlight glass skylight is respectively switched into starry sky views in the south, east and west directions. And dynamic effects of starlight flickering, moving and rotating can be realized. The starlight glass skylight realizes the breakthrough from static state to dynamic state, and is a low-cost scheme for realizing the effect.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
