LED) 14 is provided. In this HMSL, the LED 14 is used as a light source, and light emitted from the LED 14 is emitted through a red lens 12 ', thereby functioning as a red stop lamp.

[0003]

[Problems to be solved by the device]

 In such a conventional HMSL, since the interiors such as the print base 13 are exposed in the lamp chamber, the light generated by the LED 14 during lighting is diffusely reflected by the print base 13 and the illumination characteristics are improved. Deteriorated. Further, since the print base 13 and the like can be seen from the outside through the lens 12 ', there is a problem that the appearance of the HMSL is deteriorated. Also, while the lens 12 'is made of transparent red resin, the surface of the print base 13 is green due to the solder resist layer, etc. Therefore, when the lamp is not lit, the green color of the print base 13 is observed through the red lens 12'. As a result, green and red, which are complementary to each other, cause the entire HMSL to appear black and the HMSL has a poor appearance. In particular, in a car with a light body color, the difference in appearance between the rear spoiler and the HMSL becomes large, which may impair the overall design of the car. An object of the present invention is to provide an HMSL that prevents such a deterioration in appearance.

[0004]

[Means for Solving the Problems]

 According to the present invention, an inner lens having a small hole for exposing an LED is provided inside the lamp chamber of the HMSL, and the front surface of the inner lens is configured to reflect light of the same color as the vehicle body color. For example, a coating film of the same color as the vehicle body is formed on the front surface of the inner lens. Alternatively, a reflective film that reflects the painted surface of the vehicle body is formed on the front surface of the inner lens.

【Example】

 Next, the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a first embodiment of the present invention, 2 is a rear spoiler attached to a trunk lid or the like as a part of a vehicle body, and 1A is an HMSL attached to the lower rear edge of the rear spoiler 2. Is. The HMSL 1A has a lamp body 11 which is horizontally long along the lateral direction of the rear spoiler 2 and an outer lens 12 which is fixed to the front side of the lamp body 11 with an adhesive or the like. Is made of colorless transparent or translucent resin, its front surface has a curved surface shape close to an arc along the curved surface shape of the rear spoiler 2, and a light diffusion step 12a is formed inside the front surface.

In addition, a print base 13 on which a required circuit is formed is laterally extended in a lamp chamber defined by the lamp body 11 and the outer lens 12, and a large number of print bases 13 are provided on the print base 13. It supports the red LED 14. Further, an inner lens 15A having a U-shaped cross section is provided on the front side of the print base 13 and the LED 14, and both side edges of the inner lens 15A are fixed to the lamp body 11 by ultrasonic welding or the like. is doing. A large number of small holes 15a corresponding to the LEDs are opened in the inner lens 15A, and only the light emitting surface of the LED 14 is exposed to the outside of the inner lens 15A through the small holes 15a. Further, the front surface of the inner lens 15A is set to a substantially vertical angle, and a coating film 16 of the same color as the vehicle body color of the automobile, in other words, the same color as the rear spoiler 2 is formed on this front surface. It is important to form the coating film 16 so that the light reflectance is as high as possible.

With this configuration, when the lamp is turned on, the red light generated by the LED 14 is emitted to the outside while being diffused by the light diffusion step 12a of the outer lens 12, and functions as a red stop lamp. At this time, since the print base 13 is hidden by the inner lens 15A, the light from the LED 14 is not diffusely reflected by the print base 13 and the like, and the illumination characteristics are not deteriorated. Also, the green color of the print base 13 is hidden by the inner lens 15A when it is not lit, while the coating film 16 formed on the front surface of the inner lens 15A is seen through the outer lens 12 from the outside of the HMSL 1A. .. Since this coating film 16 has the same color as the rear spoiler 2, the entire HMSL 1A looks the same as the rear spoiler 2. Therefore, the appearance of the HMSL1A is completely integrated with the rear spoiler, and deterioration of the appearance of the HMSL1A is prevented.

FIG. 2 is a cross-sectional view of a second embodiment of the present invention, in which parts equivalent to those of the first embodiment are designated by the same reference numerals. In this HMSL 1B, the cross-sectional shape of the front surface of the inner lens 15B is formed into a concave surface, and a coating film 16 of the same color as the rear spoiler is formed on this concave surface. It is the same as in the above embodiment that the coating film 16 preferably has a high light reflectance. Even in this configuration, the same effect as that of the first embodiment can be obtained, and in addition to this, by making the front surface of the inner lens 15B concave, from the outside of the HMSL 1B, as shown by the arrow in the figure, The coating film 16 can be observed from a wide range of directions, and the appearance of the HMSL1B can be improved in a wide range. The front surface of the inner lens may be convex, and in this case as well, the appearance of the outer surface in a wide range can be improved in the upward and downward directions for the same reason. Further, in the first and second embodiments, if the inner lens itself is made of the material of the body color, the same effect can be obtained without providing the coating film on the front surface.

FIG. 3 is a sectional view of a third embodiment of the present invention, in which parts equivalent to those of the above-described embodiments are designated by the same reference numerals. In addition, 3 is a trunk lid of the car to which the rear spoiler is attached. In this HMSL 1C, the cross-sectional shape of the front surface of the inner lens 15C is formed as a downward inclined surface, and the reflection film 17 formed by aluminum vapor deposition or the like is formed on the inclined front surface. Further, here, the LED 14 is not projected from the small hole 15a of the inner lens 15C, but the LED 14 can be confirmed only from the front direction through the small hole 15a. According to this configuration, when viewed from the front of the HMSL 1C, the surface of the trunk lid 3 of the automobile appears to be reflected by the reflective film 17 provided on the inner lens 15C, so that the HMSL 1C can be observed as the color of the trunk lid 3. Since the rear spoiler 2 normally has the same color as the trunk lid 3, as a result, the HMSL1C looks like the same color as the rear spoiler 2, and the appearance of the HMSL1C is improved as in the above-described embodiments.

This HMSL1C reflects the color of the car body and looks like that car body color. Therefore, even if the HMSL is attached to a car body (rear spoiler) of any car body color, it looks like a color corresponding to that car body color. As a result, it is not necessary to manufacture the HMSL having a coating film that matches the color of the vehicle body as in the above-described embodiments, and the versatility can be improved. Further, since the LED 14 is not exposed from the small hole 15a of the inner lens 15C, the LED 14 becomes hard to be seen from the outside, and the red lens of the LED 14 does not deteriorate the appearance of the HMSL1 C.

FIG. 4 is a sectional view of a fourth embodiment of the present invention. In this HMSL 1D, the front surface of the inner lens 15D is an upward inclined surface, and the reflection film 17 is formed on the inclined front surface. Further, here, the step portion 15b is provided on the front surface, and the lower edge portion is located somewhat on the back surface side of the lamp chamber. In this embodiment, since the lower surface of the rear spoiler 2 is reflected by the reflective film 17 on the front surface of the inner lens 15D, the appearance color of the HMSL 1D can be the color of the rear spoiler 2. Therefore, even if there is a slight color difference between the rear spoiler 2 and the trunk lid 3, or even if the trunk lid 3 is dirty with dust or the like, the color of the lower surface of the rear spoiler 2 which is hard to be dusted is reflected. By making the HMSL1D the same color as the rear spoiler, the appearance of the HMSL1D can be improved. Further, in this embodiment, since the lower edge of the front surface of the inner lens 15D is provided with the step portion 15b in the rear direction, the same reflection is obtained as compared with the straight lens as shown by the chain line in the figure. It is possible to avoid an increase in the vertical dimension of the outer lens 12, that is, the vertical dimension of the HM SL1D, while securing the light amount.

FIG. 5 is a sectional view of a fifth embodiment of the present invention, which is basically the same as the fourth embodiment. However, here, as compared with the fourth embodiment, the front surface of the inner lens 15E forming the reflection film 17 is formed to extend straight. On top of that, a coating film 18 is formed by coating the outer upper surface of the outer lens 12 with the same color as the rear spoiler 2. According to this structure, the color of the coating film 18 formed on the outer lens 12 is reflected by the reflection film 17 on the front surface of the inner lens 15E, and the appearance of the HMSL1E can be changed to the color of the coating film 18. This configuration is effective when it is difficult to effectively reflect the lower surface of the rear spoiler when the distance between the upper surface of the HMSL and the lower surface of the rear spoiler is large.

FIG. 6 is a sectional view of a sixth embodiment of the present invention. In this HMSL 1F, the front surface of the inner lens 15F is a convex surface, and the reflection film 17 is formed on the convex surface. By doing so, the reflecting film 17 can reflect the respective surfaces of the trunk lid 3 and the rear spoiler 2, and moreover, as in the case of the second embodiment, by reflecting the light at a wide angle, the HMSL1F can be obtained. Can improve its appearance over a wide range.
