At least one light source 22a electrically connected to the PCB 20 (see FIG. 3) is optically connected to the light guide 30. The light source 22a may be disposed near one end 32 and/or the other end 33 of the light guide 30 . Here, the light source 22a may preferably be implemented as an LED, but is not limited thereto. In addition, the light source 22a preferably emits light having an amber-based wavelength band so that the indication can be easily recognized from the outside.

The light guide 30 includes a light diffusing portion 34 . The light diffusing portion 34 may be formed in a sawtooth shape to effectively diffuse light. When the first light L1 is emitted from the light source 22a by being disposed near the one end 32 of the light guide 30 through the light diffusing portion 34, the first light L1 is emitted from the light guide 30 It proceeds with diffused reflection from the inside.

Light emitted from a light source disposed at the lower end of the light guide 30 may pass through the lower surface of the light guide 30 and the diffuser 40 to be radiated through an opening formed in the reflector 50 .

While the first light L1 diffusely reflects and propagates inside the light guide 30, some of the first light L1 is incident on the first surface 31 of the light guide to the outside of the light guide 30. can escape with

The first light L1 escaping from the upper surface 31 of the light guide 30 is incident on the second surface 41b of the diffuser 40 . When the first light L1 is incident on the diffuser 40, the diffuser 40 may emit light of a predetermined wavelength band from among the first light L1 through the first surface 41a. To this end, the diffuser 40 may be coated to transmit light having a predetermined wavelength band. Alternatively, the diffuser 40 may include an optical film designed to transmit light having a predetermined wavelength band therein. The optical film may be molded into the diffuser 40 through an insert injection method.

Here, the insert injection method may mean directly injecting the printed film after molding to shape the film on which a specific pattern is printed, and seating and molding the film in an injection mold.

That is, when the indicator module 100 operates, the first light L1 emitted from the light source 22a emitting amber-based light is emitted through the light guide 30 and the diffuser 40 . In this case, in the first light L1 emitted through the diffuser 40, only the light of the wavelength band filtered through the diffuser 40, among the lights of all wavelength bands included in the first light L1, is emitted to the outside. it will be radiated The first light L1 including the filtered wavelength band may provide an indication corresponding to the operation of the indicator module 100 to the outside.

Referring to FIG. 5 , the light path of the indicator light within the indicator module 100 will be described in more detail.

Referring to FIG. 5 , the first light L1 emitted from the light source 22a is reflected from the second surface 41b of the diffuser 40 or the upper surface 31 of the light guide, or from the light guide 30. It can be radiated to the outside through the upper surface (31). The second light L2, which is the reflected light from which the first light L1 is reflected from the second surface 41b of the diffuser 40 or the upper surface 31 of the light guide 30, is reflected from the other surface of the light guide 30. can be reflected.

The third light L3 after the second light L2 is reflected from the other surface of the light guide 30 may be incident to the second surface 41b of the diffuser 40 through the upper surface 31 of the light guide. . The wavelength of the fourth light L4 incident on the diffuser 40 may change compared to that of the third light L3 due to a light conversion effect of the diffuser 40 . Specifically, as will be described later, the color reflected by the wavelength of the fourth light L4 may be included in a predetermined area on the CIE1931 color coordinate system. This will be described later in the description of FIGS. 12 and 13 . The fourth light L4 may then be emitted to the outside through the first surface 41a of the diffuser 40 . The fifth light L5 emitted from the fourth light L4 may be provided as an indication to the outside.

If the coating of the diffuser 40 is formed near the first surface 41a of the diffuser 40, the fourth light L4 may have the same or similar wavelength as the third light L3, and the fourth light L4 may have the same wavelength as the third light L3. As the light L4 changes to the fifth light L5, the color reflected by the wavelength of the fifth light L5 may be included in a predetermined area on the CIE1931 color coordinate system.

In addition, the light paths of the lights L4 and L5 generated when the light is incident to a different medium may change due to refraction.

Subsequently, an optical path when providing an indication according to a non-operating state of the indicator module 100 will be described.

Referring to FIG. 6 , external light L1 ′ may be reflected by the first surface 41a of the diffuser 40 . The light L2' reflected from the external light L1' on the first surface 41a of the diffuser 40 is transmitted to the outside in a state in which the light intensity of the wavelength band reflecting the color of the diffuser 40 is superior. can be radiated. In addition, the external light L1' may be reflected from the second surface 41b of the diffuser 40 or one surface 31 of the light guide 30. The light (L3') of the external light (L1') reflected from the second surface (41b) of the diffuser (40) or the light guide (30) is the color of the diffuser (40) according to the light conversion effect of the diffuser (40). It can be radiated to the outside in a superior state in the intensity of the wavelength band that reflects the . In addition, the external light L1 ′ may be incident to the inside of the light guide 30 and reflected from the inner surface of the light guide 30 . The light L4' reflected from the inner surface of the light guide 30 also passes through the diffuser 40, and according to the light conversion effect of the diffuser 40, the intensity of the wavelength band reflecting the color of the diffuser 40 increases. It can be radiated to the outside in a superior state.

When the external light L1' is radiated to the outside in a state in which the intensity of the wavelength band reflecting the color of the diffuser 40 is superior, the emitted light L2', L3', and L4' will be provided as an indication to the outside. can Here, as will be described later, the indication by the external light L1' may be a wavelength band representing a different color from the indication by the light source 22a. In addition, the indication by the external light L1' (when the indicator module is off) is a predetermined area on the CIE1931 color coordinate system that includes the indication when the indicator module 100 is on. can be included in addition to

Through the movement of the external light, when the indicator module 100 is not operating, the indicator module 100 may provide an indication using the external light.

In summary, external light L2 is incident on the diffuser 40, and light reflected from the first surface 41a of the diffuser 40 may provide an indication to the outside. Here, since the diffuser 40 is coated to have a predetermined wavelength band as described above or a film is formed therein, when the external light L2 is reflected from the diffuser 40, the color of the diffuser 40 is changed. Accordingly, light of a predetermined wavelength band is reflected. Through this, the indicator module 100 may provide an indication indicating the state of the vehicle to the outside even in a non-operating state.

Here, if the predetermined wavelength band represents a blue-based wavelength band, indication by light having the predetermined wavelength band may reflect that the vehicle equipped with the indicator module 100 is an electric vehicle. . As another example, if the predetermined wavelength band represents a green-based wavelength band, indication by light having the predetermined wavelength band reflects that the vehicle equipped with the indicator module 100 is a hydrogen vehicle or an eco-friendly vehicle. can do. More specifically, the light conversion member included in the indicator module 100 may include a light conversion member set to reflect external light in a wavelength range of 450 nm to 495 nm (blue-based color) when incident thereon. In addition, in detail, the light conversion member included in the indicator module 100 may include a light conversion member set to reflect external light with a wavelength range of 495 nm to 570 nm (green-based color) when incident thereon. Here, the specific color information of the indication provided by the indicator module 100 will be described in detail later.

Also, the indication according to the operating state of the indicator module 100 and the indication according to the non-operating state may include lights of different wavelength bands. That is, if the indicator outputs light in the first wavelength range when the indicator module 100 is operating, when the indicator module 100 is inactive, light in the second wavelength range is emitted as an indication by external light. can be provided. When the indicator module 100 is in an inoperative state, the external light L2 is mainly natural light and may include light of all wavelength bands. In this case, the indication appearing when the indicator module 100 is in a non-operating state may preferentially reflect the color of the optical film 40 (diffuser). On the other hand, when the indicator module 100 is in an operating state, due to the natural wavelength band of light emitted from the light source 22, even if the first light L1 passes through the optical film 40 (diffuser), the optical film 40 , the color of the diffuser) may be less reflected.

In other words, the indicator module 100 according to an embodiment converts the wavelength range of the external light L3 and/or the first light L1 through a light conversion member called an optical film and provides it to the outside, thereby providing indication It can also be said that it can provide

In addition, at least one opening 241 is included in the reflector 240, and a light source of the PCB 220 may be disposed through the opening. Alternatively, light emitted from the light source may be transmitted to the light guide 230 through the opening.

A lens 260 may be disposed on the reflector 240 and the light guide 230 . The lens 260 may be mounted on the housing 202 to surround the reflector 240 and the light guide 230 . Alternatively, the lens 260 may be mounted on the reflector 240 .

In this process, the second light L2, which is the reflected light after the third light L1 is reflected from the third surface 261 of the lens 260 or the upper surface 232 of the light guide 230, is transmitted through the light guide 230. It may be reflected on the other surface 231 of the surface or the upper surface 241 of the reflector 240.

The third light L3, after the second light L2 is reflected from the other surface 231 of the light guide 230, passes through one surface of the light guide and the third surface 261 of the lens 260 to the lens 260. can be hired as The wavelength of the fourth light L4 incident on the lens 260 may change compared to that of the third light L3 due to a light conversion effect of the lens 260 . Specifically, as will be described later, the color reflected by the wavelength of the fourth light L4 may be included in a predetermined area on the CIE1931 color coordinate system. This will be described later in the description of FIGS. 12 and 13 . The fourth light L4 may then be radiated to the outside through the fourth surface 262 of the lens 260 . The fifth light L5 emitted from the fourth light L4 may be provided as an indication to the outside.

If the coating of the lens 260 is formed on the fourth surface 262 of the lens 260, the fourth light L4 may have the same or similar wavelength as the third light L3, and the fourth light L4 may have the same wavelength as the third light L3. As (L4) changes to the fifth light (L5), the color reflected by the wavelength of the fifth light (L5) may be included in a predetermined area on the CIE1931 color coordinate system.

In addition, the light paths of the lights L4 and L5 generated when the light is incident to a different medium may change due to refraction.

Subsequently, an optical path when providing an indication according to the non-operating state of the indicator module 200 will be described.

When the indicator module 200 is not operating, the indicator module 200 may provide an indication using external light.

Specifically, when external light L'1-1 is incident on the lens 260, the light reflected from the fourth surface 262 of the lens 260 may provide an indication to the outside. Here, since the lens 260 is coated to have a predetermined wavelength band as described above or a film is molded therein, the lens 260 emits light of a predetermined wavelength band according to the color of the lens 260. will reflect Through this, the indicator module 200 may provide an indication indicating the state of the vehicle to the outside even in a non-operating state.

Referring to FIG. 11 , external light L'1-1 may be reflected by the fourth surface 262 of the lens 260. The light (L'2-1) reflected from the external light (L1') by the fourth surface 262 of the lens 260 has a superior light intensity in a wavelength band reflecting the color coated with the lens 260. can be radiated to the outside. In addition, the external light L'1-1 may be reflected from the third surface 261 of the lens 260 or one surface 232 of the light guide 230. The external light (L'1-1) reflected from the third surface 261 of the lens 260 or the light guide 230 (L'3-1) is converted according to the light conversion effect of the lens 260, The intensity of the wavelength band reflecting the color of the lens 260 may be emitted to the outside in a superior state. In addition, the external light L'1-1 may be incident to the inside of the light guide 230 and reflected from the inner surface of the light guide 230. The light (L′1-4) reflected from the inner surface of the light guide 230 also passes through the lens 260 and has a wavelength band reflecting the color of the lens 260 according to the light conversion effect of the lens 260. can be radiated to the outside with superior intensity.

When the external light (L'1-1) is radiated to the outside in a state where the intensity of the wavelength band reflecting the color of the lens 260 is superior, the emitted light (L'2-1, L'3-1, L' 4-1) may be provided as an indication to the outside. Here, as will be described later, the indication by the external light L'1-1 may be a wavelength band representing a different color from the indication by the light source 222. In addition, the indication by the external light (L'1-1) (when the indicator module is off) is on the CIE1931 color coordinate system including the indication when the indicator module 100 is on. It may be included outside of the predetermined area.

Hereinafter, a chromaticity range of an indication provided by an indicator module according to an embodiment will be described with reference to drawings.

In order to provide a clear indication to the outside of the vehicle, the indicator module 100 or 200 according to the embodiment may provide an indication including light having a predetermined wavelength band. Here, the predetermined wavelength band may be defined as an area on the CIE1931 color coordinates.

12 to 13 show regions on color coordinates of indications provided from the indicator module according to embodiments.

12 shows a corresponding area on the entire color coordinates of color information included in an indication according to an embodiment, and FIG. 11 shows a detailed area on the color coordinates of an indication according to an embodiment.

Referring to FIGS. 12 and 13 , the indication provided by the indicator module 100 may be included in a predetermined area on the CIE1931 color coordinate system. Here, the predetermined area may be an area reflecting an amber color system. More specifically, the predetermined area may be formed around a chromaticity intersection point where x = 0.585 and y is 0.415 on the CIE1931 color coordinate system. Preferably, the predetermined area may be an area of a circle having a radius of 0.04 centered on a chromaticity intersection where x=0.585 and y=0.415.

An indication provided by the indicator module 100 may have a different color according to an operating state of the indicator module 100 . Specifically, when the indicator module 100 is in an on state, the indication provided by the indicator module 100 may be included in a predetermined area on the aforementioned CIE1931 color coordinate system. Also, when the indicator module 100 is in an off state, an indication provided from the indicator module 100 may have a color different from that in a state in which the indicator module 100 is turned on. Here, the indication in a state in which the indicator module 100 is turned off may be included outside of a predetermined area on the CIE1931 color coordinate system including the indication in a state in which the indicator module 100 is turned on. .

Table 1 shows chromaticity coordinates according to measurement positions of indications provided from the indicator module 100. Specifically, the experimental results of Table 1 are experimental examples in the case where the diffuser 40 or the lens 260 of the indicator modules 100 and 200 are coated in green. The lights used in the experiment were all performed with the same brightness. Here, the diffuser 40 or the lens 260 of the indicator modules 100 and 200 includes a light conversion member that mainly reflects light reflecting a wavelength range of 495 nm to 570 nm (green series) by external light.

In addition, the chromaticity coordinates of each order indicate the chromaticity coordinates of the indication most clearly observed by the experimenters in the corresponding order.

When the green-based diffuser 40 or lens 260 is used in the indicator modules 100 and 200, the light emitted from the light sources 22a and 222 passes through the diffuser 40 and the lens 260 in advance. It can be confirmed that the visibility is increased when light in a wavelength band corresponding to a predetermined chromaticity coordinate region is provided to an external observer.

Here, although there was some change depending on the measurement height angle or measurement width angle, the x-axis value of the chromaticity intersection point of the indication most clearly observed by the subjects showed a distribution of 0.5905 to 0.5997, and the y-axis value of the chromaticity intersection point showed a distribution of 0.3997 ~ 0.4066. A detailed chromaticity region for this is shown in FIG. 11 .

When the diffuser 40 or the lens 260 of the indicator modules 100 and 200 is coated with a green color, light emitted from the light source may be output as light having a color relatively close to the green color.

Table 2 shows the results of the chromaticity test of the indication provided by the indicator module in the case of using a blue-based film.

Table 2 shows chromaticity coordinates according to measurement positions of indications provided from the indicator modules 100 and 200. Specifically, the experimental results of Table 2 are experimental examples in the case where the diffuser 40 or the lens 260 of the indicator modules 100 and 200 are coated in blue. The lights used in the experiment were all performed with the same brightness. Here, the diffuser 40 or the lens 260 of the indicator modules 100 and 200 includes a light conversion member that reflects light reflecting a wavelength range of 450 nm to 495 nm (blue series) by external light.

In addition, the chromaticity coordinates of each order indicate the chromaticity coordinates of the indication most clearly observed by the experimenters in the corresponding order.

Even according to Table 2, when the blue-based diffuser 40 or lens 260 is used in the indicator modules 100 and 200, the light emitted from the light sources 22a and 222 is emitted from the diffuser 40 or the lens ( 260), it can be confirmed that visibility is increased when light in a wavelength band corresponding to a predetermined chromaticity coordinate region is provided to an external observer.

Here, the x-axis value of the chromaticity intersection point of the indication most clearly observed by the test subjects showed a distribution of 0.5842 ~ 0.5904, and the y-axis value of the chromaticity intersection point showed a distribution of 0.4092 ~ 0.4132. A detailed chromaticity region for this is shown in FIG. 11 .

As can be confirmed through Tables 1 and 2, when the light emitted through the light sources 22 and 222 passes through the diffuser 40 or the lens 260 and is radiated to the outside, the wavelength corresponding to the predetermined chromaticity coordinate region It is preferable that the light of the band is emitted. The indicator modules 100 and 200 according to an embodiment may provide a clear indication to an outside observer by radiating light in a predetermined wavelength band to the outside.

Referring back to FIG. 12, both when the blue-based optical filter and the green-based optical filter are applied to the indicator modules 100 and 200, the chromaticity intersection point is included within 0.04 centered on x=0.585 and y=0.415. Indication by light having a wavelength in a region may be provided.

When the diffuser 40 or the lens 260 of the indicator modules 100 and 200 is coated with a blue color, light emitted from the light source may be output as light having a color relatively close to the blue color.

That is, the indicator module 100 according to the embodiment is a predetermined region on the chromaticity coordinate system due to the combination of the wavelength band of light emitted by the light sources 22a and 222 and the wavelength band of light transmitted by the optical film (diffuser or lens). Light of a wavelength band corresponding to the image may be provided as an indication.
