Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A light transmission assembly 10 according to an embodiment of the present invention is described below with reference to fig. 1-4.
As shown in fig. 1 to 4, according to the light transmission member 10 of the embodiment of the present invention, the light transmission member 10 includes a support 11, a filter member 12, and an electromagnetic actuator 13. Specifically, as shown in fig. 1, the bracket 11 defines a mounting cavity 111, the filter assembly 12 is disposed in the mounting cavity 111, and the electromagnetic actuator 13 is disposed on an outer wall surface of the bracket 11.
As shown in fig. 1, the holder 11 has a mounting cavity 111 therein, and light is adapted to pass through the holder 11. It is understood that the mounting cavity 111 may be used to provide a receiving space for some components of the light transmission assembly 10, and light may pass through the mounting cavity 111.
As shown in fig. 1 and 2, the filter assembly 12 can filter light (here, "filter light" is understood to mean that light with specific wavelength can pass through the filter assembly 12, and light with non-specific wavelength can not pass through the filter assembly 12), and the filter assembly 12 is rotatably disposed in the mounting cavity 111. Therefore, by arranging the rotatable light filtering component 12 in the mounting cavity 111, the included angle between the light and the normal line of the light filtering component 12 can be changed by controlling the rotation angle of the light filtering component 12, so as to change the absorption and reflection capabilities of the light filtering component 12 on the light with different wavelengths, so that the light filtering component 12 can filter out part of the light with the wavelengths, and control the light with specific wavelengths to pass through the light filtering component 12, thereby controlling the color of the light passing through the light filtering component 12 (it should be noted that the light with different wavelengths presents different colors in the vision). It will be appreciated that, with the different rotation angles of the filter assembly 12, the color of the light passing through the filter assembly 12 is also different, so that the variety of colors of the light passing through can be improved
For example, as shown in fig. 1 and fig. 3, when the filter assembly 12 is in a natural state (here, "natural state" may be understood as a state when the filter assembly 12 is not subjected to an external force), an angle between the light ray a and a normal line of the filter assembly 12 is θ 1. As shown in fig. 2 and 4, the filter assembly 12 is in a state of being forced to rotate, at this time, an included angle between the light ray a and a normal of the filter assembly 12 is θ 2, and the sizes of θ 1 and θ 2 are different.
It can be understood that, the color adjustment of the light passing through the light transmitting component 10 is realized by controlling the rotation angle of the light filtering component 12, which can simplify the adjustment operation, improve the convenience of the light transmitting component 10 in adjusting the color of the light passing through, and improve the diversity of the color of the light passing through, thereby improving the user experience.
As shown in fig. 1, an electromagnetic actuator 13 may be used to actuate the filter assembly 12. It should be noted that by controlling the magnetic force variation of the electromagnetic driving component 13, the driving force provided by the electromagnetic driving component 13 to the light filtering component 12 can be different, so that the rotation angle of the light filtering component 12 can be controlled, and further, the variation of the incident angle of the light can be controlled.
According to the light-transmitting component 10 of the embodiment of the present invention, the rotatable light-filtering component 12 is disposed in the mounting cavity 111, and the color of the light passing through the light-filtering component 12 can be adjusted by controlling the rotation angle of the light-filtering component 12, so that the operation process of adjusting the light-transmitting color can be simplified, the convenience of adjusting the color of the light passing through the light-transmitting component 10 can be improved, the diversity of the color of the light passing through can be improved, and the user experience can be further improved.
As shown in fig. 5, according to some embodiments of the invention, the light transmissive component 10 may include a buffer medium 1111, and the buffer medium 1111 may be disposed within the mounting cavity 111. Therefore, when the electromagnetic driving component 13 drives the filtering component 12 to rotate, the buffering component can provide buffering resistance for the filtering component 12, so that the filtering component is prevented from rotating too fast, the probability of vibration or loosening of the filtering component 12 caused by large motion inertia of the filtering component 12 is reduced, and the stability and reliability of the light-transmitting component 10 can be improved.
As shown in fig. 3 and 5, according to some embodiments of the present invention, the filter assembly 12 may include a rotating shaft 121 and a first filter 122. As shown in fig. 5, the rotation shaft 121 may be coupled to the bracket 11, the first filter may be coupled to the rotation shaft 121, and the first filter may be rotatable with respect to the rotation shaft 121. Therefore, by controlling the rotation of the first filter, the included angle between the light and the normal of the first filter 122 can be changed, so as to change the absorption and reflection capability of the first filter 122 on part of the light, and further change the color of the light which can pass through the first filter 122.
For example, as shown in fig. 3, the rotating shaft 121 is located above the first filter 122, the upper end of the first filter 122 is connected to the rotating shaft 121, the lower end of the first filter 122 is a free end, and the first filter 122 can rotate around the rotating shaft 121 in a circumferential direction.
As shown in fig. 3, according to some embodiments of the invention, the first filter 122 may include a first light-transmitting layer 1221 and a first mirror layer 1222, the first light-transmitting layer 1221 may be connected to the rotation shaft 121, and the first mirror layer 1222 may be attached to the first light-transmitting layer 1221. Thus, by configuring the first filter 122 as the first light-transmitting layer 1221 and the first mirror layer 1222, the first light-transmitting layer 1221 can be used as an attachment structure of the light-transmitting medium and the first mirror layer 1222, so that light can be transmitted through the first light-transmitting layer 1221. The first mirror layer 1222 may serve as a light absorbing or reflecting structure for absorbing or reflecting light of a specific wavelength, so that the filtering capability of the first filter 122 may be improved.
Further, the first light-transmitting layer 1221 may be glass. Therefore, by forming the first light-transmitting layer 1221 from glass, the light-transmitting effect of the first light-transmitting layer 1221 can be improved by using the advantages of good glass permeability and easiness in molding, and cost can be saved. The first mirror layer 1222 can be a metal film or a photosensitive glass. It should be noted that the metal film can selectively transmit visible light and block infrared rays and ultraviolet rays. Thus, by configuring the metal film as the first mirror layer 1222, it is possible to block harmful light and control the color of light that can pass through the first mirror layer 1222, thereby improving the filtering capability of the first filter 122.
In addition, the refractive index of the photosensitive glass changes under the irradiation of light, and the color of the light that can pass through the photosensitive glass changes along with the change of the refractive index of the photosensitive glass, so that the filtering effect of the first mirror layer 1222 can be improved.
As shown in fig. 3 and 4, according to some embodiments of the present invention, the filter assembly 12 further includes a second filter 123, and the second filter 123 may be stacked with the first filter 122. Therefore, the second filter 123 and the first filter 122 may be stacked, so that when the light passing through the first filter 122 passes through the second filter 123, the second filter 123 may absorb or reflect the light passing through the first filter 122 again, so that the light may selectively pass through the second filter 123, thereby improving the reliability of the filter assembly 12 and the diversity of the light passing through the filter assembly 12.
As shown in fig. 3 and 4, a gap may be formed between the first filter 122 and the second filter 123. Thus, a reflective space may be provided for the light passing through the first filter 122 by using the gap between the first filter 122 and the second filter 123, the light passing through the first filter 122 may be irradiated toward the second filter 123 and reflected on the second filter 123 toward the surface of the gap, and the reflected light may be irradiated toward the first filter 122 and reflected again on the first filter 122 toward the surface of the gap.
It can be understood that light can be reflected between the first filter 122 and the second filter 123 for multiple times, and along with the difference of the rotation angle of the filter assembly 12, the reflection routes of light with different wavelengths between the first filter 122 and the second filter 123 are also different, so that a portion of light interferes with each other and is weakened, and another portion of light interferes with each other and is strengthened, so that the strengthened portion of light can pass through the second filter 123, and the filtering capability of the filter assembly 12 to light and the color temperature adjusting capability to the passing light are further strengthened.
As shown in fig. 3 and 4, the second filter 123 may be connected to the rotating shaft 121, and the second filter 123 may rotate relative to the rotating shaft 121. Therefore, by controlling the rotation angle of the second optical filter 123, the included angle between the light passing through the first optical filter 122 and the normal of the second optical filter 123 can be adjusted, so as to change the absorption and reflection capabilities of the second optical filter 123 on light with different wavelengths, and further adjust the color of the light passing through the second optical filter 123.
As shown in fig. 3 and 4, according to some embodiments of the invention, the first filter 122 includes a second transparent layer 1231 and a second mirror layer 1232, the first transparent layer 1221 can be connected to the rotation shaft 121, and the second mirror layer 1232 can be attached to the second transparent layer 1231. Thus, by configuring the second filter 123 as the second light-transmitting layer 1231 and the second mirror layer 1232, the second light-transmitting layer 1231 can be used as an attachment structure of the light-transmitting medium and the second mirror layer 1232, so that light can be transmitted through the second light-transmitting layer 1231. The second mirror layer 1232 may serve as a light absorbing or reflecting structure for absorbing or reflecting light of a specific wavelength, so that the filtering capability of the second filter 123 may be improved.
For example, as shown in fig. 3 and 4, the first filter 122 is located at the front side of the second filter 123, and the first filter 122 and the second filter 123 are spaced apart from each other in the front-back direction. The back sidewall of the first filter 122 can be the first mirror layer 1222, the front sidewall of the second filter 123 can be the second mirror layer 1232, and the first mirror layer 1222 can define a gap with the second mirror layer 1232.
It should be noted that when the light passing through the first filter 122 impinges on the second mirror layer 1232, part of the light is reflected, and the reflected light is irradiated toward the first mirror layer 1222 and reflected again by the first mirror layer 1222.
It will be appreciated that light passing through the first filter 122 can be reflected between the first mirror layer 1222 and the second mirror layer 1232 multiple times, and the reflection paths of light of different wavelengths between the first mirror layer 1222 and the second mirror layer 1232 can be changed with the rotation angle of the filter assembly 12, so that the interference enhancement of part of the light can be controlled and passed through the second filter 123, and the color diversity of the light passing through the light-transmitting assembly 10 can be adjusted.
According to some embodiments of the present invention, the second light-transmitting layer 1231 can be glass and the second mirror layer 1232 can be a metal film or a photosensitive glass. Thus, by configuring the glass as the second light-transmitting layer 1231, light-transmitting properties of the second light-transmitting layer 1231 can be improved, and cost can be reduced. And by using a metal film or a photosensitive glass as the second mirror layer 1232, the ability of the second filter 123 to adjust the color change of the light passing through can be improved by utilizing the selective passing of the light of different wavelengths through the metal film or the photosensitive glass. According to some embodiments of the invention, the support 11 may be glass. Therefore, the characteristics of good light transmission and easy forming of the glass can be utilized, the light transmission of the bracket 11 is improved, and the cost is reduced.
As shown in fig. 1 and 5, the electromagnetic actuator 13 may be disposed on an outer surface of the bracket 11 according to some embodiments of the present invention. Thus, the magnetic field of the electromagnetic driver 13 can cover the mounting cavity 111 to provide a driving force for the filter assembly 12 disposed in the mounting cavity 111. As shown in fig. 5, the electromagnetic drivers 13 may be provided at both left and right ends of the holder 11, whereby adverse effects of the electromagnetic drivers 13 on the light transmittance of the holder 11 can be reduced.
Specifically, permanent magnets may be disposed at the left and right ends of the filtering component 12, the magnetic field of the electromagnetic driving component 13 may be mutually excluded from or attracted to the permanent magnets to drive the filtering component 12 to rotate, and the process of controlling the rotation angle of the filtering component 12 by the electromagnetic driving component 13 is as follows:
the magnetic field of the electromagnetic driving component 13 can repel or attract the permanent magnet on the filter component 12 to drive the filter component 12 to rotate, and the torque of the gravity of the filter component 12 relative to the rotating shaft 121 is different along with the change of the rotation angle of the filter component 12. When the torque of the filter assembly 12 and the repulsive force or attractive force between the electromagnetic driving member 13 and the filter assembly 12 tend to be equal, the filter assembly 12 stops rotating and maintains balance. It will be appreciated that the magnitude of the repulsive or attractive force between the electromagnetic actuator 13 and the filter assembly 12 is proportional to the strength of the magnetic field of the electromagnetic actuator 13. Thus, by adjusting the magnetic field strength of the electromagnetic actuator 13, the rotation angle of the filter assembly 12 can be controlled. For example, when the rotation angle of the filter assembly 12 needs to be increased, the intensity of the magnetic field of the electromagnetic driving member 13 can be increased.
Further, as shown in fig. 1 and 5, there may be a plurality of electromagnetic drivers 13, and there may also be a plurality of filter assemblies 12, and each set of filter assemblies 12 corresponds to at least one electromagnetic driver 13. That is, any set of filter assemblies 12 may correspond to one or more electromagnetic drivers 13. Therefore, by arranging the plurality of groups of light filtering components 12, the capability of the light transmitting component 10 for adjusting the color of the light passing through can be improved, and the probability that part of light avoids the light filtering components 12 when the light passes through the light transmitting component 10 can be reduced, so that the reliability of the light transmitting component 10 is improved.
Therefore, by arranging each set of filtering components 12 corresponding to at least one electromagnetic driving component 13, the layout of the electromagnetic driving components 13 can be optimized, and the cost is saved; and the reliability of the electromagnetic driving piece 13 for driving the filter assembly 12 to rotate can be improved. For example, when one of the electromagnetic drivers 13 is damaged, the remaining electromagnetic drivers 13 may still drive the filter assembly 12 to rotate.
For example, as shown in fig. 1 and fig. 5, five sets of filter assemblies 12 are disposed in the mounting cavity 111, the five sets of filter assemblies 12 are arranged in the vertical direction, and two electromagnetic drivers 12 are correspondingly disposed on the left side of any set of filter assemblies 12, one of the electromagnetic drivers 12 is disposed on the front surface of the bracket 11, and the other is disposed on the rear surface of the bracket 11. As shown in fig. 2, when the electromagnetic driving member 12 drives the filter assembly 12 to rotate, the electromagnetic driving member 12 located on the front surface of the bracket 11 may attract the permanent magnet at the left end of the filter assembly 12, and the electromagnetic driving member 12 located on the rear surface of the bracket 11 may repel the permanent magnet at the left end of the filter assembly 12, so as to drive the filter assembly 12 to rotate together.
As shown in fig. 1 and 5, two electromagnetic drivers 12 are correspondingly disposed on the right side of any one of the filter assemblies 12, and one of the electromagnetic drivers 12 is disposed on the front surface of the bracket 11, and the other is disposed on the rear surface of the bracket 11. As shown in fig. 2, when the electromagnetic driving member 12 drives the filter assembly 12 to rotate, the electromagnetic driving member 12 located on the front surface of the bracket 11 can attract the permanent magnet at the right end of the filter assembly 12, and the electromagnetic driving member 12 located on the rear surface of the bracket 11 can repel the permanent magnet at the right end of the filter assembly 12, so as to drive the filter assembly 12 to rotate together.
The light transmission member 10 according to an embodiment of the present invention is described in detail below with reference to fig. 1 to 4. It is to be understood that the following description is illustrative only and is not intended to be in any way limiting.
As shown in fig. 1 and 2, the light transmission assembly 10 includes a support 11, a filter assembly 12, and an electromagnetic actuator 13. As shown in fig. 1, the bracket 11 may define a mounting cavity 111, the filter assembly 12 may be disposed in the mounting cavity 111, the electromagnetic actuator 13 may be disposed on an outer surface of the bracket 11, and the electromagnetic actuator 13 may be opposite to two ends of the filter assembly 12 to drive the filter assembly 12 to rotate. Therefore, by controlling the rotation of the filter assembly 12, the included angle between the light and the normal of the filter assembly 12 can be changed, so as to change the absorption and reflection capability of the filter assembly 12 for the light with different wavelengths, and further adjust the color of the light passing through the filter assembly 12.
As shown in fig. 3, the filter assembly 12 includes a rotating shaft 121, a first filter 122 and a second filter 123. As shown in fig. 5, the rotating shaft 121 penetrates the mounting cavity 111 along the left-right direction, and the rotating shaft 121 is connected to the left and right ends of the bracket 11. As shown in fig. 3, the first filter 122 and the second filter 123 are both located below the rotating shaft 121, and the upper ends of the first filter 122 and the second filter 123 are both connected to the rotating shaft 121, so that the first filter 122 and the second filter 123 can both rotate around the rotating shaft 121.
As shown in fig. 3, the first filter 122 is located at the front side of the second filter 123, and the first filter 122 and the second filter 123 are spaced apart from each other in the front-back direction. Thus, the first filter 122 and the second filter 123 may define a space, and the light passing through the first filter 122 may be reflected multiple times in the space.
As shown in fig. 3, the first filter 122 includes a first light-transmitting layer 1221 and a first mirror layer 1222, the first mirror layer 1222 is attached to the first light-transmitting layer 1221, and a rear sidewall of the first filter 122 may be the first mirror layer 1222. The second filter 123 includes a second transparent layer 1231 and a second mirror layer 1232, the second mirror layer 1232 is attached to the second transparent layer 1231, the front sidewall of the second filter 123 can be the second mirror layer 1232, and the first mirror layer 1222 and the second mirror layer 1232 define a gap.
It should be noted that when the light passing through the first filter 122 impinges on the second mirror layer 1232, part of the light is reflected, and the reflected light is irradiated toward the first mirror layer 1222 and reflected again by the first mirror layer 1222. It is understood that light passing through the first filter 122 may be reflected multiple times between the first mirror layer 1222 and the second mirror layer 1232. Therefore, a part of light rays can be mutually interfered and weakened, and the other part of light rays can be mutually interfered and strengthened, so that the strengthened part of light rays can pass through the second filter, and the filtering capability of the filtering component 12 on the light rays and the color temperature adjusting capability of the passing light rays are further strengthened.
As shown in fig. 5, an electromagnetic actuator 13 is provided on the outer surface of the holder 11, the electromagnetic actuator provided on the left side of the holder 11 faces the left end of the filter assembly 12, and the electromagnetic actuator 13 provided on the right side of the holder 11 faces the right end of the filter assembly 12. It should be noted that permanent magnets may be disposed at left and right ends of the filtering assembly 12, and the magnetic field of the electromagnetic driving component 13 may repel or attract the permanent magnets to drive the filtering assembly 12 to rotate.
As shown in fig. 5, a buffer medium 1111 is disposed in the mounting cavity 111, and the buffer medium 1111 is filled around the filter assembly 12. Therefore, when the electromagnetic driving component 13 drives the filtering component 12 to rotate, the buffering component can provide buffering resistance for the filtering component 12, so that the filtering component is prevented from rotating too fast, the probability of vibration or loosening of the filtering component 12 caused by large motion inertia of the filtering component 12 is reduced, and the stability and reliability of the light-transmitting component 10 can be improved.
