Description

  The present invention relates to a rear combination lamp for a vehicle.

  Patent Document 1 describes a lamp structure including a reflector, light emitting means such as a bulb or a light emitting diode, an inner lens, and an outer lens.

  The inner surface of the reflector is a reflective surface that has been subjected to a reflective treatment such as aluminum vapor deposition or reflective coating. The light emitting means is attached to the center of the reflector.

  The inner lens has a large number of convex portions and through portions. The outer lens is a transparent clear lens.

JP 2006-302782 A

  In the above-mentioned Patent Document 1, the convex portion is subjected to a reflection process such as aluminum vapor deposition, reflective coating, or reflective printing, so that when external light enters, the convex portion is reflected and shines. It is described that the light emission of the light emitting means is made uniform by performing half aluminum vapor deposition (semi-transmission) on the part.

  However, from the above-mentioned Patent Document 1, it is impossible to know the technical idea of emitting red light that satisfies the legal requirements to the outside when turned on, and emitting a good-looking color other than the red to the outside when not turned on.

  In view of such circumstances, the present invention provides a rear combination lamp for a vehicle that emits red light that satisfies legal requirements to the outside when turned on, and emits a good-looking color other than the red to the outside when not turned on. It is aimed.

  A rear combination lamp for a vehicle according to the present invention includes a light emitting means for generating red light, a transparent outer lens that covers an opening of a case, and a red light generated from the light emitting means to diffuse the inner surface of the outer lens. A transparent inner lens that leads to a wide area, a transflective film is formed on the inner surface of the outer lens, and a yellow paint film is formed on the outer surface of the outer lens. .

  In this configuration, when the light emitting means is turned on, the red light generated from the light emitting means is diffused by passing through the transparent inner lens, and the wide area on the inner surface of the transparent outer lens is passed through the transflective film. And is emitted to the outside by passing through the outer lens and the yellow coating film.

  At this time, since the red light generated by the light emitting means passes through the yellow coating film, the light emitted to the outside becomes a red light that satisfies the legal requirements although it becomes a slightly thin red light.

  On the other hand, when the light emitting means is not lit, when external light such as headlight light or sunlight of another vehicle is incident on the transparent outer lens, the external light is reflected by the transflective film. As a result, the light passes through the transparent outer lens and the yellow paint film and is emitted to the outside.

  At this time, the external light is reflected by the transflective film and passes through the yellow paint film, so that the light emitted to the outside appears to be gold, for example.

  Thus, since it looks different at the time of lighting and at the time of non-lighting, it can contribute to the improvement of the design.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the rear combination lamp | ramp for vehicles which discharge | releases the red color which satisfy | fills a legal requirement at the time of lighting outside, and discharge | releases the color of the appearance other than red when not lighting.

It is sectional drawing which shows one Embodiment of the rear combination lamp | ramp for vehicles which concerns on this invention. It is a schematic diagram for demonstrating the mode at the time of lighting of the rear combination lamp of FIG. It is a schematic diagram for demonstrating the mode at the time of the non-lighting of the rear combination lamp of FIG. FIG. 2 is a chromaticity diagram showing a chromaticity range of outside emitted light when the rear combination lamp of FIG. 1 is lit and when not lit.

  BEST MODE FOR CARRYING OUT THE INVENTION Best modes for carrying out the present invention will be described in detail below with reference to the accompanying drawings.

  1 to 4 show an embodiment of the present invention. In the figure, reference numeral 1 denotes an entire rear combination lamp for a vehicle.

  The rear combination lamp 1 includes a case 2, a light-emitting diode (LED) 3, an outer lens 4, and an inner lens 5.

  The light emitting diodes 3 generate red light, and are densely mounted on a resin substrate 6 vertically and horizontally.

  Although not shown in detail, the operation of the light emitting diode 3 such as lighting and non-lighting is controlled by a control device composed of various electronic components mounted on the control board 7. The board 6 and the control board 7 on which the light emitting diode 3 is mounted are attached to the inside of the case 2 via an appropriate bracket 8.

  The outer lens 4 is a lid that covers the opening of the case 2 and is a transparent clear lens.

  The inner lens 5 diffuses the red light generated from the light emitting diode 3 and guides it to a wide area, preferably the entire area of the inner surface of the outer lens 4, and is attached to the inner side of the outer lens 4 near the opening of the case 2. . The inner lens 5 is a transparent clear lens.

  A transflective film 9 is formed on the inner surface of the outer lens 4, and a yellow paint film 10 is formed on the outer surface of the outer lens 4.

  The semi-transmissive reflective film 9 is formed by half vapor deposition such as aluminum. The yellow coating film 10 is formed by painting, for example, a yellow paint.

  Next, with reference to FIG. 2 and FIG. 3, the light transmission mode at the time of lighting of the rear combination lamp 1 of the said structure and a non-lighting is demonstrated.

  First, when the light emitting diode 3 is turned on, as shown in FIG. 2, the red light generated from the light emitting diode 3 is diffused by passing through the transparent inner lens 5 and transparent through the transflective film 9. The light is incident on a wide area, preferably the entire area, on the inner surface of the outer lens 4, and is emitted to the outside by passing through the outer lens 4 and the yellow coating film 10.

  At this time, since the red light generated by the light emitting diode 3 passes through the yellow coating film 10, the light emitted to the outside becomes a red light that satisfies the legal requirements although it becomes a slightly thin red light (in the hatching of FIG. 4). See chromaticity area shown). FIG. 4 is an enlarged view of a part of a chromaticity diagram (CIE 1931) defined by the International Lighting Commission (abbreviation: CIE, French: Commission internationale de l'eclairage).

  On the other hand, when the light-emitting diode 3 is not lit, as shown in FIG. 3, when external light such as headlight light or sunlight from another vehicle enters the outer lens 4, the external light is reflected by the semi-transmissive reflection It is reflected by the film 9 and passes through the transparent outer lens 4 and the yellow paint film 10 and is emitted to the outside.

  At this time, since the external light is reflected by the semi-transmissive reflective film 9 and passes through the yellow paint film 10, the light emitted to the outside appears to be, for example, gold (with cross-hatching in FIG. 4). See chromaticity area shown).

  Thus, since it looks different at the time of lighting and at the time of non-lighting, it can contribute to the improvement of the design.

  The rear combination lamp 1 of this embodiment has a configuration in which the red light generated from the light emitting diode 3 is directly emitted to the outer lens 4 side, thereby eliminating the reflector as described in Patent Document 1. This is advantageous for simplification and reduction of product cost.

  In addition, this invention is not limited only to the said embodiment, It can change suitably in the range equivalent to the claim and the said range.

  For example, in the said embodiment, it does not specifically limit about the internal shape and external shape of the rear combination lamp 1, It can change arbitrarily.

  Further, the mounting layout of the light emitting diodes 3 on the substrate 6 is not particularly limited, and can be designed in an arbitrary layout.

  The present invention can be suitably used for a rear combination lamp for a vehicle.
