Abstract

In a display lamp configured to emit light from a light source by directing the light emitted from the light source towards the front of the lamp via a light-transmitting control member, the aforementioned area is made to appear to glow in a different manner when the lamp is not lit and when the lamp is lit. [Solution] The light-transmitting control member 40 is constructed as a two-color molded product comprising a transparent resin part 40P and an opaque resin part 40S. In this case, a portion of region Z is composed only of the transparent resin part 40P, while the surrounding region is constructed as a laminated structure of the transparent resin part 40P and the opaque resin part 40S. Furthermore, a half-deposited film 60 is formed on the rear surface of at least a portion of region Z, and a white light-diffusing member 50 is placed on the rear side of the light-transmitting control member 40 of the lamp. This causes a portion of region Z of the light-transmitting control member 40 to appear to shine with a silvery metallic color due to external light reflection when the lamp is not lit, and to appear to shine uniformly with white light due to the transmission of light emitted from the light source 20 when the lamp is lit.

Summary of the Invention

Problems to be Solved by the Invention

[0006] As such a configuration of the display lamp, it is desirable from the viewpoint of enhancing the display function that when the lamp is not lit, a partial area of the light transmission control member appears to shine due to external light, and when the lamp is lit, the above partial area appears to shine in a manner different from when the lamp is not lit.

[0007] The present invention has been made in view of these circumstances, and aims to provide a display lamp configured to emit light in a portion of a light-transmitting control member by irradiating the light emitted from a light source toward the front of the lamp through the light-transmitting control member, thereby causing the portion of the light-transmitting control member to emit light, such that the portion of the lamp appears to light up in a different manner when the lamp is not lit and when the lamp is lit. [Means for solving the problem]

[0008] The present invention aims to achieve the above objective by modifying the configuration of the light-transmitting control member.

[0009] In other words, the indicator light fixture according to the present invention is In a display lamp configured to emit light from a light source by directing the light emitted from the light source towards the front of the lamp via a light-transmitting control member, The above light-transmitting control member is configured as a two-color molded product comprising a transparent resin portion and an opaque resin portion, wherein a portion of the region is composed solely of the transparent resin portion, and the surrounding region of the portion is composed of a laminated structure of the transparent resin portion and the opaque resin portion. The above light-transmitting control member has a configuration in which a half-deposited film is formed on the rear surface of at least a portion of the above region. The light-transmitting control member is characterized in that a light-diffusing means is provided on the rear side of the light fixture for causing the light emitted from the light source to be incident on the aforementioned partial area as colored diffused light.

[0010] The above-mentioned "indicator light fixture" is not particularly limited in type, as long as it is configured so that a portion of the light-transmitting control member can emit light. For example, luminous emblems and indicator lamps attached to vehicles can be used.

[0011] The type of "light source" mentioned above is not particularly limited; for example, light-emitting elements such as light-emitting diodes and incandescent bulbs can be used.

[0012] The specific location and size of the "partial area" mentioned above are not particularly limited.

[0013] The "light diffusion means" described above is not particularly limited in its specific configuration, as long as it is provided on the rear side of the light-transmitting control member of the lamp so as to cause the light emitted from the light source to be incident on a certain area as colored diffused light.

[0014] The term "colored diffused light" above refers to light that diffuses while being colored with any desired color. For example, white diffused light or blue diffused light can be used. [Effects of the Invention]

[0015] The indicator light fixture according to the present invention is configured to emit light in a portion of the light-transmitting control member by irradiating the light emitted from the light source toward the front of the light fixture via the light-transmitting control member. The light-transmitting control member is configured as a two-color molded product comprising a transparent resin portion and an opaque resin portion, and the portion of the light-transmitting control member is composed solely of the transparent resin portion, while the surrounding area of ​​the portion of the light-transmitting control member is composed of a laminated structure of the transparent resin portion and the opaque resin portion. Furthermore, a half-deposited film is formed on at least the rear surface of the portion of the light-transmitting control member, and a light diffusion means is provided on the rear side of the light fixture of the light-transmitting control member to cause the light emitted from the light source to be incident on the portion of the light-transmitting control member as colored diffused light. As a result, the following effects can be obtained.

[0016] In other words, when the light fixture is not lit, the light-transmitting control member causes the aforementioned area to appear to glow with a silvery metallic color (for example, an aluminum-like metallic color) due to the reflection of ambient light incident on that area by the half-deposited film, while the surrounding area appears to glow with the color of the opaque resin part.

[0017] On the other hand, when the light fixture is lit, the light-transmitting control member receives light from the light source, which is irradiated towards the front of the fixture via the light diffusion means and the half-deposited film. As a result, a portion of the area appears to glow uniformly with the color of the diffused light, while the surrounding area appears dark.

[0018] Therefore, the light-transmitting control member can be configured such that when the lamp is not lit, the above-mentioned partial area appears to shine with a silver metallic color due to external light reflection, while when the lamp is lit, the above-mentioned partial area appears to shine uniformly with the color of the colored diffused light due to transmission of the emitted light from the light source.

[0019] Thus, according to the invention of the present application, in a display lamp configured to emit a part of the light-transmitting control member by irradiating the emitted light from the light source toward the front of the lamp through the light-transmitting control member, the above-mentioned partial area can appear to shine in different modes when the lamp is not lit and when the lamp is lit. Thereby, the display function as a display lamp can be enhanced.

[0020] In the above configuration, further, if the light diffusing means is constituted by a light diffusing member disposed on the rear side of the lamp of the light-transmitting control member, the following operational effects can be obtained.

[0021] That is, as a configuration of the light diffusing means, for example, it is also possible to configure by laminating a colored coating film on the surface of a half-vapor deposition film formed on the rear surface of the light-transmitting control member. However, when such a configuration is adopted, it is necessary to perform strict film thickness management of the colored coating film. On the other hand, by configuring the light diffusing means with a light diffusing member, strict film thickness management and the like as in the case of adopting a colored coating film are not required, and thereby the lamp configuration can be made inexpensive.

[0022] In that case, if the light diffusing member is constituted by a white resin member, when the lamp is not lit, the above-mentioned partial area can appear to shine with a silver metallic color, while when the lamp is lit, the above-mentioned partial area can appear to shine uniformly with white, and thereby the display function as a display lamp can be further enhanced.

[0023] Also, if the light diffusing member is configured such that an opening is formed in a part located on the rear side of the lamp of the opaque resin part, the weight can be reduced without impairing the function as the light diffusing means.

[0024] In the above configuration, further, if a transparent optical member configured to emit the light emitted from the light source toward the light-transmitting control member is disposed between the light source and the light-transmitting control member, uniform light emission in the above partial region when the lamp is lit can be promoted.

[0025] At that time, as the optical member, with a configuration including an incident portion for allowing the light emitted from the light source to enter, and first and second reflecting surfaces for sequentially totally reflecting the light incident from this incident portion, as the configuration of the first reflecting surface, it is formed so as to totally reflect the light incident from the incident portion on the front surface of the optical member in the outer peripheral direction around a virtual axis extending in the front-rear direction of the lamp. On the other hand, as the configuration of the second reflecting surface, with a configuration composed of a plurality of reflecting elements formed on the rear surface of the optical member, if these plurality of reflecting elements are configured to totally reflect the light totally reflected by the first reflecting surface toward the light-transmitting control member, while reducing the depth dimension of the display lamp, uniform light emission in the above partial region when the lamp is lit can be realized.

[0027] Embodiments of the present invention will be described below with reference to the drawings.

[0028] Figure 1 is a front view showing a display lamp 10 according to one embodiment of the present invention. Figure 2 is a cross-sectional view taken along line II-II in Figure 1.

[0029] In Figures 1 and 2, the direction indicated by X is "forward of the lamp," the direction indicated by Y is "leftward" (or "rightward" when viewed from the front of the lamp), which is perpendicular to "forward of the lamp," and the direction indicated by Z is "upward." The same applies to figures other than Figures 1 and 2.

[0030] As shown in Figures 1 and 2, the indicator light 10 according to this embodiment is a light-emitting emblem that is attached to the front end of a vehicle and has a vertically symmetrical configuration.

[0031] The display lamp 10 is configured such that when light emitted from two light sources 20 is directed forward of the lamp via a light-transmitting control member 40, a portion of the light-transmitting control member 40 appears to emit light when viewed from the front of the lamp, thereby functioning as a light-emitting emblem.

[0032] Specifically, the indicator light fixture 10 has a configuration in which two light sources 20 are incorporated together with an optical member 30 and a light diffusion member 50 in a light chamber formed by a lamp body 12 and a light-transmitting cover 14 attached to the front end opening of the lamp body 12. In this configuration, the light-transmitting cover 14 is formed to extend along the surface shape of the vehicle body panel 100 shown by the dashed line in Figure 2, and this light-transmitting cover 14 is provided with the function of a light-transmitting control member 40.

[0033] A portion of the light-transmitting control member 40, region Z, is a region for forming a light-emitting shape as a light-emitting emblem, and is composed of a central region ZA formed in a rightward V-shape (leftward V-shape when viewed from the front of the lamp) and an annular region ZB formed in a horizontally elongated elliptical ring around the central region ZA. In this case, the left edge of the central region ZA extends to a position where it overlaps with the annular region ZB at two points, upper and lower. A certain gap is provided between the left edge of the central region ZA and the annular region ZB.

[0034] Both light sources 20 are white light-emitting diodes, and are positioned vertically at a certain distance apart with their light-emitting surfaces 20a facing forward (specifically, towards the front of the lamp). This pair of upper and lower light sources 20 are mounted on a common substrate 22 and supported by the lamp body 12.

[0035] The optical element 30 is a colorless, transparent resin component (for example, a polycarbonate resin component) and has a horizontally elongated oval shape when viewed from the front of the lamp. It is positioned to cover a pair of upper and lower light sources 20 from the front of the lamp. The optical element 30 is configured to emit light from the two light sources 20 as substantially parallel light towards the front of the lamp. The optical element 30 has a peripheral edge 38 formed on the outer circumference of the substrate 22 so as to extend toward the rear of the lamp, and is supported by the lamp body 12 at this peripheral edge 38.

[0036] The optical element 30 includes a pair of upper and lower incident portions 32 for receiving light emitted from a pair of upper and lower light sources 20, a pair of upper and lower first reflective surfaces 34 for totally reflecting the light incident from these upper and lower incident portions 32, and a second reflective surface 36 for totally reflecting the light totally reflected from these upper and lower first reflective surfaces 34.

[0037] Each of the pair of upper and lower incident portions 32 is positioned on the rear surface 30b of the optical member 30 so as to be in the direction of the front of each of the pair of upper and lower light sources 20.

[0038] Each of the upper and lower pair of first reflective surfaces 34 is positioned on the front surface 30a of the optical member 30 so as to be located in the direction of the front of each of the upper and lower pair of incident portions 32 of the lamp.

[0039] Next, the specific configuration of the light transmission control member 40 will be described.

[0040] Figure 3 is a detailed view of part III of Figure 2. In Figure 3, the indicator light fixture 10 is shown with the front of the light fixture facing upwards.

[0041] As shown in Figure 3, the light-transmitting control member 40 is configured as a two-color molded product comprising a transparent resin portion 40P and an opaque resin portion 40S. Specifically, the light-transmitting control member 40 is configured as a primary molded product with a colorless, transparent transparent resin portion 40P, and as a secondary molded product with an opaque (e.g., black) resin portion 40S. In this configuration, a portion of the light-transmitting control member 40 (i.e., the central region ZA and the annular region ZB) is composed solely of the transparent resin portion 40P, while the surrounding region Z is configured as a laminated structure of the transparent resin portion 40P and the opaque resin portion 40S.

[0042] The peripheral edge 42 of the light-transmitting control member 40 is formed to extend towards the rear of the lamp while maintaining the laminated structure of the transparent resin portion 40P and the opaque resin portion 40S. An annular flange portion 44 extending in the outer direction is formed at the rear end edge of this peripheral edge portion 42, and an annular leg portion 46 projecting toward the rear of the lamp is formed on this annular flange portion 44. These annular flange portion 44 and annular leg portion 46 are composed solely of the opaque resin portion 40S. The light-transmitting control member 40 is supported by the lamp body 12 at its annular flange portion 44 and annular leg portion 46.

[0043] The light-transmitting control member 40 has a configuration in which a half-deposited film 60 is formed on at least a portion of the rear surface Z. Specifically, this half-deposited film 60 is formed over substantially the entire area of ​​the rear surface 40b of the light-transmitting control member 40 by a vacuum deposition process of aluminum or the like. In this case, the half-deposited film 60 is not formed on the inner surface of the peripheral edge 42 of the light-transmitting control member 40.

[0044] Furthermore, the front surface 40a of the light-transmitting control member 40 is coated with a hard coat (not shown) over the entire area of ​​the portion composed of the transparent resin part 40P.

[0045] The light-diffusing member 50 is made of a white resin material (for example, a polycarbonate resin material) and is formed to extend along the rear surface 40b of the light-transmitting control member 40. The peripheral edge 52 of the light-diffusing member 50 is formed to extend towards the rear of the lamp along the inner circumferential surface of the peripheral edge 42 of the light-transmitting control member 40, and an annular flange portion 54 extending in the outer direction is formed at its rear end edge. The light-diffusing member 50 is supported by the lamp body 12 at its annular flange portion 54.

[0046] Figure 4 is a rear view showing the optical component 30 as a single unit.

[0047] As shown in Figures 3 and 4, each incident portion 32 of the optical member 30 is formed to protrude in a frustoconical shape from the rear surface 30b of the optical member 30 toward the rear of the lamp, and its rear end surface 32a is configured as an incident surface into which the emitted light from each light source 20 is incident. In this case, each incident portion 32 is formed around a virtual axis Ax that extends in the front-rear direction of the lamp, passing through the light-emitting center of each light source 20. As a result, each incident portion 32 causes the emitted light from each light source 20 to be incident on the optical member 30 in a direction toward the virtual axis Ax from its rear end surface 32a.

[0048] The front surface 30a of the optical element 30 is formed in a planar shape along a vertical plane perpendicular to the virtual axis Ax. Each first reflective surface 34 of the optical element 30 is composed of an annular convex curved surface centered on the virtual axis Ax, and is formed to totally reflect the incident light from each incident part 32 outward around the virtual axis Ax. In this case, each first reflective surface 34 totally reflects the incident light from each incident part 32 as a converged light that is close to parallel light, directed towards the rear of the lamp within the plane containing the virtual axis Ax.

[0049] The second reflective surface 36 of the optical member 30 is composed of a plurality of reflective elements 36s formed over the entire area of ​​the rear surface 30b of the optical member 30. In the upper half of the second reflective surface 36, these plurality of reflective elements 36s are arranged concentrically around a virtual axis Ax located on the upper side (i.e., the axis passing through the light-emitting center of the light source 20 located on the upper side), and each has a sawtooth cross-sectional shape. In the lower half of the second reflective surface 36, these plurality of reflective elements 36s are arranged concentrically around a virtual axis Ax located on the lower side, and each has a sawtooth cross-sectional shape. Each of these plurality of reflective elements 36s is formed to totally reflect the light emitted from the light source 20, which has been totally reflected by the first reflective surface 34, toward the front of the lamp.

[0050] Figure 5 is a front view showing the indicator light fixture 10 in the unlit state, and Figure 6 is a front view showing the indicator light fixture 10 in the illuminated state.

[0051] As shown in Figure 5, when the light fixture is not lit, the light transmission control member 40 appears to glow in a silvery metallic color (e.g., an aluminum-like metallic color) when ambient light incident on a certain region Z is reflected by the half-deposited film 60, while the surrounding region appears to glow in the color of the opaque resin part 40S (e.g., black).

[0052] On the other hand, as shown in Figure 6, when the light fixture is lit, the light-transmitting control member 40 is illuminated in front of the light fixture by the light emitted from the pair of upper and lower light sources 20 through the light-diffusing member 50 and the half-deposited film 60. As a result, a portion of area Z appears to glow uniformly with the color of colored diffuse light (i.e., white), while the surrounding area appears dark.

[0053] Next, the effects and advantages of this embodiment will be described.

[0054] The indicator light fixture 10 according to this embodiment is configured to emit light in a portion of the light-transmitting control member 40 by irradiating the light emitted from the light source 20 toward the front of the light fixture via the light-transmitting control member 40. The light-transmitting control member 40 is configured as a two-color molded product comprising a transparent resin portion 40P and an opaque resin portion 40S. Furthermore, the portion of the Z is composed only of the transparent resin portion 40P, and the surrounding area of ​​the portion of the Z is composed of a laminated structure of the transparent resin portion 40P and the opaque resin portion 40S. In addition, a half-deposited film 60 is formed on the rear surface 40b of the light-transmitting control member 40 (i.e., at least the rear surface of the portion of the Z). Moreover, a light-diffusing member 50 is arranged on the rear side of the light fixture of the light-transmitting control member 40 as a light-diffusing means for causing the light emitted from the light source 20 to be incident on the portion of the Z as colored diffused light. Thus, the following effects can be obtained.

[0055] In other words, when the light fixture is not lit, the light transmission control member 40, as shown in Figure 5, causes the ambient light incident on a certain region Z to be reflected by the half-deposited film 60, resulting in a silvery metallic color in that region Z and the surrounding region appearing in the color of the opaque resin part 40S.

[0056] On the other hand, when the light fixture is lit, the light-transmitting control member 40 is irradiated in front of the light fixture through the light-diffusing member 50 and the half-deposited film 60, so as shown in Figure 6, a part of area Z appears to glow uniformly with the color of colored diffused light, while the surrounding area appears dark.

[0057] Therefore, the light-transmitting control member 40 can be configured so that when the luminaire is not lit, a portion of area Z appears to glow with a silvery metallic color due to reflection of ambient light, while when the luminaire is lit, a portion of area Z appears to glow uniformly with a colored diffuse light color due to transmission of light emitted from the light source 20.

[0058] As described above, in this embodiment, in a display lamp 10 configured to emit light from a light source 20 by irradiating it in front of the lamp through the light-transmitting control member 40, a portion of area Z of the light-transmitting control member 40 can be made to appear to light up in a different manner when the lamp is not lit and when the lamp is lit. This enhances the display function of the display lamp 10.

[0059] In particular, in this embodiment, the light diffusion means for causing the light emitted from the light source 20 to be incident on a certain region Z as colored diffused light is composed of a light diffusion member 50 arranged on the rear side of the light transmission control member 40, so the following effects can be obtained.

[0060] In other words, the light diffusion means can be configured, for example, by laminating a colored coating film onto the surface of a half-deposited film 60 formed on the rear surface 40b of the light-transmitting control member 40. However, if such a configuration is adopted, strict control of the film thickness of the colored coating film becomes necessary. In contrast, by configuring the light diffusion means with a light diffusion member 50, strict film thickness control, as required when using a colored coating film, becomes unnecessary, thereby making the lighting fixture configuration less expensive.

[0061] Furthermore, in this embodiment, since the light diffusing member 50 is made of a white resin material, when the light fixture is not lit, a portion of area Z appears to glow with a silvery metallic color, while when the light fixture is lit, a portion of area Z appears to glow uniformly with white light, thereby further enhancing the display function of the indicator light fixture 10.

[0062] Furthermore, in this embodiment, a transparent optical member 30 is placed between the light source 20 and the light-transmitting control member 40, configured to direct the light emitted from the light source 20 toward the light-transmitting control member 40. This promotes uniform illumination of a certain region Z when the lamp is lit.

[0063] In this embodiment, the optical member 30 includes an incident section 32 into which light emitted from the light source 20 is incident, and first and second reflective surfaces 34 and 36 that sequentially totally reflect the light incident from the incident section 32. The first reflective surface 34 is formed on the front surface 30a of the optical member 30 to totally reflect the light incident from the incident section 32 outward around a virtual axis Ax extending in the front-rear direction of the lamp. The second reflective surface 36 is composed of a plurality of reflective elements 36s formed on the rear surface 30b of the optical member 30. These plurality of reflective elements 36s are configured to totally reflect the light totally reflected by the first reflective surface 34 as parallel light toward the light transmission control member 40. As a result, the depth dimension of the display lamp 10 can be reduced, and uniform illumination of a portion of area Z when the lamp is lit can be achieved.

[0064] In the above embodiment, the optical member 30 was described as having a configuration in which the light totally reflected by the first reflective surface 34 of the multiple reflective elements 36s formed on its rear surface 30b is totally reflected as parallel light toward the light transmission control member 40. However, it is also possible to configure it to totally reflect the light as diffuse light toward the light transmission control member 40.

[0065] In the above embodiment, the light diffusing member 50 was described as being made of a white resin material, but in addition to pure white, other colors such as milky white or cream can also be used for the white color.

[0066] In the above embodiment, the region Z for forming the luminous shape as a luminous emblem was described as being composed of a rightward V-shaped central region ZA and a horizontally elongated elliptical ring region ZB. However, it is also possible to configure it to be a different shape. For example, the ring region ZB of the region Z can be configured to extend along the peripheral edge 42 of the light-transmitting control member 40. By adopting such a configuration, the peripheral edge 42 of the light-transmitting control member 40 can also be made to appear to emit light when the lamp is lit. In this case, the peripheral edge 42 of the light-transmitting control member 40 can also be made of only a transparent resin portion 40P.

[0067] In the above embodiment, the display lamp 10 was described as being equipped with an optical member 30 for controlling the transmission of light emitted from the light source 20. However, it is also possible to adopt a configuration in which a reflector is provided to reflect the light emitted from the light source 20 toward the light diffusion member 50 instead of this optical member 30, or to adopt a configuration in which the light emitted from the light source 20 is incident directly onto the light diffusion member 50.

[0068] In the above embodiment, it was described that light sources 20 are arranged at two locations, upper and lower. However, it is also possible to configure the system so that the two light sources 20 are arranged at positions different from those in the above embodiment, and it is also possible to configure the system so that one or more light sources 20 are arranged.

[0069] Next, a modified example of the above embodiment will be described.

[0070] First, a first modified example of the above embodiment will be described.

[0071] Figures 7 and 8 are similar to Figures 1 and 3, showing the indicator light fixture 110 according to this modified example.

[0072] As shown in Figures 7 and 8, the basic configuration of this modified example is the same as that of the above embodiment, but the configuration of the light diffusing member 150 is slightly different from that of the above embodiment.

[0073] In other words, the light-diffusing member 150 of this modified example is also made of a white resin member formed to extend along the rear surface 40b of the light-transmitting control member 40, and is supported by the lamp body 12 at an annular flange portion 154 formed at the rear end edge of its peripheral portion 152. However, it differs from the above embodiment in that three openings 150a, 150b, and 150c are formed in the portion of the opaque resin portion 40S located on the rear side of the lamp (i.e., in a region outside a part of the light-transmitting control member 40 region Z when viewed from the front of the lamp).

[0074] Of these three openings 150a to 150c, two openings 150a and 150b are formed to be located on the inner circumference of the annular region ZB on both the upper and lower sides of the central region ZA, while the remaining opening 150c is formed to be located on the inner circumference of the annular region ZB on the left side of the central region ZA.

[0075] Even when this modified configuration is adopted, the same effects and advantages as in the above embodiment can be obtained. That is, the light-transmitting control member 40 can be configured so that when the lamp is not lit, a portion of area Z appears to shine with a silvery metallic color due to reflection of ambient light, while when the lamp is lit, a portion of area Z appears to shine uniformly with the color of colored diffuse light (i.e., white) due to the transmission of light emitted from the light source 20.

[0076] Furthermore, by adopting the configuration of this modified example, it is possible to reduce the weight of the light-diffusing member 150 without impairing its function as a light-diffusing means. This also allows for a reduction in the weight of the indicator light fixture 110.

[0077] Next, a second modified example of the above embodiment will be described.

[0078] Figure 9 is a diagram similar to Figure 3, showing the indicator light fixture 210 according to this modified example.

[0079] As shown in Figure 9, the basic configuration of this modified example is the same as that of the above embodiment, but the light diffusing member 50 as in the above embodiment is not arranged. Instead, a colored coating film 270 is laminated on the surface of a half-deposition film 60 formed on the rear surface 40b of the light-transmitting control member 40. This colored coating film 270 is made up of a white coating film and is formed over substantially the entire area of ​​the rear surface 40b of the light-transmitting control member 40.

[0080] In addition, in the indicator light fixture 210 according to this modified example, the shape of the lamp body 212 differs in part from that of the above embodiment because the light diffusion member 50 is not arranged as in the above embodiment.

[0081] In the indicator light fixture 210 according to this modified example, when the light fixture is not lit, the light transmission control member 40 causes the light transmitted to appear as a silvery metallic color in a certain area Z, as the ambient light incident on that area Z is reflected by the half-deposited film 60, while the surrounding area appears as the color of the opaque resin part 40S.

[0082] On the other hand, when the light fixture is lit, the light-transmitting control member 40 is illuminated in front of the light fixture by the light emitted from the light source 20 through the colored coating film 270 and the half-deposited film 60, so that a part of area Z appears to light up uniformly with the color of the colored coating film 270, while the surrounding area appears dark.

[0083] Therefore, the light-transmitting control member 40 can be configured so that when the luminaire is not lit, a portion of area Z appears to glow with a silvery metallic color due to reflection of ambient light, while when the luminaire is lit, a portion of area Z appears to glow uniformly with the color of colored diffuse light (i.e., white) due to the transmission of light emitted from the light source 20.

[0084] Even when adopting this modified configuration, substantially the same effects and advantages as in the above embodiment can be obtained.

[0085] Furthermore, by adopting the configuration of this modified example, it is possible to further thin the indicator light fixture 210 and reduce the number of its components.

[0086] It should be noted that the numerical values ​​shown as specifications in the above embodiments and their modified forms are merely examples, and these may be set to different values ​​as appropriate.

[0087] Furthermore, the present invention is not limited to the configurations described in the above embodiments and their modifications, and various other modified configurations can be adopted. [Explanation of symbols]
