1A to 1B are diagrams for explaining a mirror/mood light/advertisement board integrated device according to an embodiment.

1A to 1B, the mirror/mood light/advertisement board integrated device 100 according to an embodiment does not transmit an image to the outside by using emission or reflection of light, but rather using scattering of light through haze marking. This allows the image to be transmitted externally.

In other words, the mirror/mood light/advertisement board integrated device 100 may operate so that an image is projected to the outside by using scattering of light (it may implement an image in which light spreads).

In addition, the mirror/mood lamp/advertisement board integrated device 100 can implement functions of a mood lamp and an advertisement board with high light uniformity and efficiency at low cost.

To this end, the mirror / mood light / advertisement board integrated device 100 includes a case 110 , a marking plate 120 , a luminance reduction film 130 , a half mirror 140 , a light emitting unit 150 and a haze film 160 . may include.

Specifically, the mirror / mood light / advertising board integrated device 100 is a case 110, a marking plate 120, a luminance reduction film 130 and a half mirror 140 are sequentially stacked, the marking plate 120 , the light emitting unit 150 may be formed on one side of the luminance reduction film 130 and the half mirror 140 .

Meanwhile, the mirror/mood light/advertisement board integrated device 100 may be implemented only with the case 110 , the marking plate 120 , the half mirror 140 , the light emitting unit 150 , and the haze film 160 .

In other words, the mirror/mood light/advertisement board integrated device 100 may implement an image only with the marking plate 120 and the half mirror 140 without the luminance reduction film 130 .

At this time, as the brightness of the external light introduced from the outside increases, the transmittance of the half-mirror 140 should decrease. Conversely, the reflectance of the half-mirror 140 may be very high. That is, the characteristics of the half-mirror 140 can be implemented to some extent indoors, but only the function as a mirror can be implemented outdoors because the reflectivity of the half-mirror 140 is fixed to a high degree.

Hereinafter, the mirror/mood light/advertisement board integrated device 100 provided with the luminance reduction film 130 will be described.

The case 110 according to an embodiment may be formed under the marking plate 120 and include barrier ribs for mounting the marking plate 120 and the luminance reduction film 130 .

In other words, the case 110 according to an embodiment is formed of a plastic opaque frame including a barrier rib, so that external light can be prevented from being introduced from the lower and side surfaces of the mirror/mood light/advertisement board integrated device 100 . .

The case 110 may be formed by machining a predetermined groove in one plate. For example, a case 110 for mounting the marking plate 120 and the luminance reduction film 130 may be formed by forming a groove with a thickness of 1T in a plate having a thickness of 3T.

In addition, the case 110 may be formed by separately forming a 'ㅁ'-shaped plate and a 'C'-shaped plate, and bonding the two formed plates through laser welding.

According to one side, the case 110 may include a lower case, a middle case, and an upper case.

For example, the lower case may be a 'ㅁ'-shaped plate, the middle case may be a 'C'-shaped plate, and the upper case may be a frame-shaped plate or a transparent 'ㅁ'-shaped plate.

According to one side, the case 110 may be processed through at least one of laser welding, computer numerical control (CNC) injection molding, and waterjet processing to be bonded to the half mirror 140 .

Preferably, the case 110 may be bonded to the half mirror 140 through laser welding, and the marking plate 120 may be detachably attached through one side on which the partition wall is not formed.

Specifically, when laser cutting is performed at a predetermined power and speed in a state in which the half-mirror 140 is superimposed on the upper part of the case 110 on which the marking plate 120 and the luminance reduction film 130 are mounted, by laser heat As the acrylic (material of the case 110 and the half mirror 140) melts, the two pieces of acrylic can be naturally joined. That is, the mirror / mood lamp / billboard integrated device 100 can be implemented without an additional bonding process such as acrylic adhesive, UV resin, etc., and can implement a neat edge without post-processing.

In addition, the case 110 may be designed so that no partition wall is formed on any one of the four surfaces of the case 110, and the case 110 bonded to the half mirror 140 is formed through the surface on which the partition wall is not formed. 120) is designed to be replaceable so that various images can be easily and easily replaced.

The marking plate 120 according to an embodiment may include a haze marking corresponding to an image to be displayed, and may scatter internal light through the haze marking.

According to one side, the haze marking may be an opaque marking formed due to a physical or thermal scratch applied on the marking plate 120 which is a transparent plastic material.

For example, the marking plate 120 may be formed of a transparent acrylic material, the haze marking may be formed through a physical scratch using a pen or a separate machine, and is formed through a thermal scratch using heat at a predetermined temperature. could be

The luminance reduction film 130 according to an embodiment may be provided between the marking plate 120 and the half mirror 140 to reduce the luminance of internal light scattered through haze marking.

For example, the luminance reduction film 130 may be a plastic material (eg, acrylic), or a semi-transparent dark gray sheet paper or a semi-transparent dark gray coating film. For example, the translucent dark gray sheet paper may be attached to at least one of the aluminum deposition surface of the marking plate 120 and the half mirror 140, and the translucent dark gray coating film may be deposited/coated on the aluminum deposition surface of the half mirror. have.

According to one side, the luminance reduction film 130 may reduce the luminance of at least one of the scattered internal light and the external light input through the half mirror 140 by 20% to 50%. Preferably, the brightness reduction film 130 may reduce the brightness of at least one light by 50%.

More specifically, in the case of an existing smart mirror or mirror frame, in order to prevent the effect of reflecting the internal image by external light and to implement the image only with internal light, a polarizing film and a retarder or An external light blocking film, etc. should be additionally combined. However, the mirror/mood light/advertisement board integrated device 100 can provide effective visibility at a lower cost by using only the luminance reduction film 130 without additional means.

As a more specific example, when the luminance reduction film 130 is a film that reduces the luminance of light by 50%, the mirror/mood lamp/advertisement board integrated device 100 adjusts the luminance of external light input through the half mirror 140 to 100 , the luminance of external light decreases to 25 while passing through the half mirror 140 and the luminance reduction film 130, and when the reduced external light is reflected and emitted again to the outside, the luminance reduction film 130 and the half It can be transmitted with a luminance of 6 through the mirror 140 .

In addition, when the luminance reduction film 130 is a film that reduces the luminance of light by 50%, the mirror / mood lamp / advertisement board integrated device 100 assumes that the luminance of the internal light is 100, the luminance of the internal light is the luminance of the reduced film 130 . ) and the half-mirror 140 may be transmitted with a luminance of 25.

That is, the mirror/mood light/advertisement board integrated device 100 uses only the luminance reduction film 130 and the half mirror 140 to reduce the luminance of external light to a level that the user cannot perceive, and maximize the luminance of internal light. By transmitting efficiently, it is possible to provide more efficient visibility at a lower cost.

Meanwhile, the transmittance of the luminance reduction film 130 may be varied by a control signal received from the outside. For example, the luminance reduction film 130 may be formed of a combination of a polarizing film and a liquid crystal, and may change transmittance through arrangement of liquid crystals according to an applied control signal.

More specifically, the mirror/mood light/advertisement board integrated device 100 may include a controller for varying the transmittance of the brightness reduction film 130, and based on a control signal received from the controller, the brightness reduction film The transmittance of 130 can be controlled. For example, the control signal may be in the form of at least one of an electrical signal, temperature, physical force, and other external stimulus.

That is, the mirror/mood light/advertisement board integrated device 100 controls the transmittance of the luminance reducing film 130 to easily control the reflectance and transmittance for the entire device, so that the function of the billboard can be easily implemented even in bright daytime. can

According to one side, the transmittance of the luminance reduction film 130 may be determined through the following equation.

[Equation]

In the above equation, q is the transmittance of the luminance reducing film, p is the transmittance of the half mirror, x is the external light input through the half mirror, y is the brightness when the external light is reflected by the marking plate and emitted to the outside again, z is the brightness when the scattered internal light is emitted to the outside, k may represent the brightness of the scattered internal light in the marking plate.

및

의 조건을 만족할 수 있다.In addition, since the transmittance of light cannot exceed 1, it is difficult for people to perceive light of brightness of 10 lx or less in general.

and

condition can be satisfied.

In other words, it may be designed such that the transmittance of the luminance reduction film 130 is variable or fixed with the transmittance calculated through the above equation.

이어야 하므로, q는 1/7보다 같거나 작아야 한다. 즉, p = 0.7일 때

(밝기 감소가 86%, 투과율이 14%)로 결정될 수 있다. As a more specific example, when p = 0.7 (reflectance of 30%, transmittance of 70%) assuming that x = 1,000 in the above equation,

, so q must be less than or equal to 1/7. That is, when p = 0.7

(brightness reduction is 86%, transmittance is 14%).

이어야 하므로, q는 1/5보다 같거나 작아야 한다. 즉, p = 0.5일 때

(밝기 감소가 80%, 투과율이 20%)로 결정될 수 있다.In addition, when p = 0.5 (reflectance of 50%, transmittance of 50%) assuming that x = 1,000 in the above equation,

, so q must be less than or equal to 1/5. That is, when p = 0.5

(brightness reduction is 80%, transmittance is 20%).

이어야 하므로, q는 1보다 같거나 작아야 한다. 즉, p = 0.1일 때

(밝기 감소가 0%, 투과율이 100%)로 결정될 수 있다.In addition, when p = 0.1 (reflectance of 90%, transmittance of 10%) assuming that x = 1,000 in the above equation,

, so q must be less than or equal to 1. That is, when p = 0.1

(brightness reduction is 0%, transmittance is 100%).

The half-mirror 140 according to an exemplary embodiment may display an image by transmitting internal light scattered through the marking plate 120 to the outside. In other words, the half-mirror 140 may display an image by transmitting internal light with reduced luminance through the luminance reduction film 130 to the outside.

On the other hand, the mirror/mood light/advertisement board integrated device 100 may additionally include a translucent fog color sheet paper to implement scattering of light for a color image using the provided translucent fog color sheet paper, and the translucent fog color sheet paper is marked It may be disposed on the plate 120 .

According to one side, the light emitting unit 150 may irradiate internal light in at least one direction of the marking plate 120 , the luminance reduction film 130 , and the half mirror 140 through at least one light emitting diode.

In addition, the light emitting unit 150 is irradiated with internal light of a first brightness in the direction of the marking plate, internal light of a second brightness smaller than the first brightness is irradiated in the direction of the luminance reduction film, and in the direction of the half mirror At least one light emitting diode may be disposed so that internal light having a third brightness less than 2 brightness is irradiated.

In other words, the light emitting unit 150 is irradiated with internal light of a first brightness, which is a brightness of a predetermined strong magnitude, in the direction of the marking plate, and internal light of a second brightness that is a brightness of a predetermined intermediate magnitude in the direction of the brightness reduction film At least one light emitting diode may be disposed (designed) to be irradiated and to be irradiated with internal light having a third brightness, which is a brightness of a predetermined weak magnitude, in the direction of the half mirror.

According to one side, the haze film 160 may be formed on the irradiated surface to which the internal light is irradiated from the light emitting unit 150 .

According to one side, the haze film 160 may be a micro-segregated liquid crystal (MSLC) haze film formed by mixing a polymer and a low-molecular liquid crystal material.

That is, the haze film 160 may be formed while droplets of a micrometer level liquid crystal material are spontaneously phase-separated and dispersed in a polymer matrix, and the light emitting part ( 150), it is possible to improve the uniformity of the internal light by diffusing the irradiated internal light.

More specifically, the MSLC haze film 160 is used to evenly provide internal light to the marking plate 120 when at least one light emitting diode is disposed at regular intervals, and is implemented with a very thin thickness using a silicon cover. The light transmittance is higher than that of the scattering method, and the droplet size is small and uniform, so that the light can be evenly scattered (expanded) rather than irregularly scattered.

2 is a view for explaining a mood light mode of the mirror/mood light/advertisement board integrated device according to an embodiment.

Referring to FIG. 2, in the mirror/mood light/advertisement board integrated device according to an embodiment, the internal light irradiated from the light emitting unit provided at the bottom is input to the luminance reduction film, and the inputted internal light haze formed on the surface of the marking plate By being scattered in the marking, the image corresponding to the haze marking is reflected on the outer surface of the half mirror through light scattering, thereby improving the uniformity of the image.

For example, the case, the marking plate, the luminance reduction film, and the half mirror of the mirror/mood light/advertisement board integrated device according to an embodiment may be formed of an acrylic material, and the acrylic material used at this time is denser than the air. (because the refractive index is large), total reflection can be achieved when light travels.

In other words, the mirror/mood light/advertisement board integrated device according to an embodiment is formed of an acrylic material and totally reflects the scattered internal light, thereby minimizing the decrease in the intensity of the scattered internal light.

3 is a view for explaining an embodiment of the mirror / mood lamp / billboard integrated device according to an embodiment.

Referring to FIG. 3, (a) of FIG. 3 shows a mirror/mood light/advertisement board integrated device without a luminance reduction film, and FIG. 3(b) is a mirror/mood light/advertisement board integrated device according to an embodiment. The mirror mode of the device is shown, and FIG. 3 ( c ) shows the mood light mode of the mirror/mood lamp/advertisement board integrated device according to an embodiment.

As shown in (a) of FIG. 3 , when the luminance reduction film is not provided, the mirror/mood light/advertisement board integrated device exposes the haze marking to the outside as it is due to external light input through the half mirror in the mirror mode. Visibility problems may appear.

Accordingly, as shown in (b) to (c) of FIG. 3, the mirror/mood light/advertisement board-integrated device according to an embodiment further includes a luminance reduction film, thereby improving visibility and improving light uniformity and efficiency. can improve

Specifically, when the luminance reduction film is a film that reduces the luminance of light by 50%, assuming that the luminance of external light input through the half mirror is 100 in the mirror/mood lamp/advertisement board integrated device according to an embodiment, the luminance of external light is reduced to 25 while passing through the half mirror and the luminance reduction film, and when the reduced external light is reflected and emitted again, it can be transmitted again with a luminance of 6 through the luminance reduction film and the half mirror.

That is, the mirror/mood light/advertisement board integrated device according to an embodiment may improve the visibility problem by reducing the brightness of external light through the brightness reduction film and the half mirror to a level that cannot be recognized by the user.

In addition, when the luminance reduction film is a film that reduces the luminance of light by 50%, assuming that the luminance of the internal light is 100 in the mirror / mood lamp / billboard integrated device according to an embodiment, the luminance of the internal light is the luminance reduction film and the half mirror It can be transmitted with a luminance of 25 while passing through.

That is, the mirror/mood light/advertisement board integrated device according to an embodiment can transmit internal light with maximum efficiency while ensuring user visibility through the luminance reduction film and the half mirror.

4A to 4B are diagrams for explaining an example of a light emitting unit of a mirror/mood light/advertisement board integrated device according to an embodiment.

4A to 4B , reference numeral 400a denotes a front image of the light emitting unit according to an exemplary embodiment, and reference numeral 400b denotes a side image of the light emitting unit according to an exemplary embodiment.

Referring to reference numerals 400a to 400b, the light emitting unit according to an embodiment may include at least one light emitting diode 410 for irradiating internal light in the direction of the luminance reduction film.

For example, the at least one light emitting diode 410 may be implemented in the same color or in different colors. Also, the at least one light emitting diode 410 may be mounted on a flexible material such as a silicon material.

On the other hand, the light emitting unit according to an embodiment further includes an on/off switch 420 and a C-type power terminal 430, so that mode switching between a mirror mode and a mood light mode and ease of power supply can improve

5 is a view for explaining an example of the scattering distance of the haze film of the mirror / mood lamp / billboard integrated device according to an embodiment.

Referring to FIG. 5 , (a) of FIG. 5 shows a scattering distance d of a haze layer according to an embodiment, and each of FIGS. 5(b) to (e) according to an embodiment The scattering distances of the haze film are 0 cm, 1 cm, 4 cm and 10 cm.

Specifically, the light emitting unit of the mirror/mood light/advertisement board integrated device according to an embodiment includes a plurality of light emitting diodes, but each of the plurality of light emitting diodes is disposed at regular intervals from each other, so that it is difficult to secure uniformity of light.

More specifically, when the intensity of the internal light irradiated from the light emitting part is very strong, such a uniformity problem can be ignored, but due to the nature of the invention to implement the mood lamp function, the intensity of the light cannot be strengthened beyond a certain intensity, so Additional means are needed to solve the problem.

Accordingly, the mirror/mood light/advertisement board-integrated device according to an embodiment may additionally include a haze film between the light emitting unit and the luminance reducing film in order to secure the uniformity of light, and the haze film is formed of a polymer and It may be a micro-segregated liquid crystal (MSLC) haze film formed by mixing a low-molecular liquid crystal material.

According to (a) to (e) of Figure 5, the haze film according to an embodiment, as the distance (scattering distance) from the image increases, light is scattered, and it can be seen that the image reaches a level at which the image cannot be recognized.

In particular, when the scattering distance is 10 cm, it can be confirmed that the light is spread to a very large range.

In other words, the mirror / mood lamp / billboard integrated device according to an embodiment arranges a haze film having a haze effect (scattering effect) between the luminance reducing film and the light emitting part, and internal light irradiated with the luminance reducing film through the light emitting part By scattering the light, uniformity of light can be ensured.
