Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a vehicle lamp, and more particularly to a vehicle lamp having a side marker lens around which a side reflex reflector is formed.

[Prior art]

There is a so-called rear combination lamp as an example of a vehicular lamp, and a turn signal lamp, a stop lamp, etc. are generally integrated. In addition to the above, this rear combination lamp may be required to be equipped with a side reflex reflector (hereinafter, referred to as RR) that reflects light from the outside or a lamp called a side marker. For example, there are different requirements depending on the destination country. A part of the outer lens of the rear combination lamp is formed in a concave shape so that the parts common to both cases where this requirement is made and cases where this requirement is not made are formed in a concave shape.
Lenses for the RR and side markers can be fitted, or a dummy lens having the same properties as the other parts of the outer lens can be fitted.

[Problems to be Solved by the Invention] FIG. 7 shows a cross section when the lenses for the side RR and the side marker are fitted in the concave portion of the outer lens.
A lens 3 is integrally attached to a part of the outer lens 2, and a lens step 4a for transmitting light from the bulb 6 in a desired direction is formed in a central portion 4 of the lens 3 so as to function as a side marker. Has been done, lens 3
The side RR5 is formed in the other regions of. At the side RR5, light from the outside once enters the lens and is reflected on the back side of the lens. Therefore, when the lens thickness is X, the light L ₁ reflected by the side RR 5 is 2X + α
It passes through the lens 3 for a distance of. On the other hand, the light L ₂ emitted from the bulb 6 for the side marker provided in the lamp passes through the lens for the distance X. Although this lens 3 has a red color, the reflected light of the side RR becomes a deeper red color and the light of the side marker becomes a lighter red color due to the difference in the passing distance. Both the reflected light from the side RR and the light emitted from the side marker require a red color with an appropriate darkness, so if a lens is formed so that the red color of the reflected light from the side RR is appropriate, the side marker transmits the light. The red color of the light becomes faint. On the contrary, if a lens is formed so that the red color of the transmitted light of the side marker is appropriate, the red color of the reflected light at the side RR becomes too dark.

A bulb mounting portion for mounting the bulb 6 is integrally formed on the lamp body 1, and a hole 8a for inserting the bulb 6 is opened. But the eighth
As shown in the drawing, when it is not required to attach the side marker to the vehicular lamp, the hole 8a is closed, but the bulb mounting portion 8 remains. Therefore, the uneven shape of the bulb mounting portion 8 becomes a shadow and can be seen from the outside through the dummy lens 3a, which causes a problem that the vehicular lamp is unattractive.

This invention was made in order to solve the above problems, and both the reflected light at the side RR and the red color of the side marker transmitted light can be made appropriate, and if the side marker lamp bulb is not installed, An object of the present invention is to provide a vehicular lamp in which the uneven shadow of the bulb mounting portion formed on the lamp body is difficult to see through from the outside.

[Means for Solving the Problems]

In order to achieve the above object, the vehicular lamp according to the present invention has a concave portion formed in a part of a red outer lens,
A side marker lens on which a side reflex reflector is formed around is a vehicle lamp mounted on a concave portion of the outer lens, and a red lens is provided at a position corresponding to the side reflex reflector on the back side of the side marker portion. It is characterized by being provided.

[Action]

By overlapping the red lens provided at the position corresponding to the side marker portion with the lens portion of the side marker, the red color of the transmitted light at the side marker, which has been apt to be red in the past, can be made dark. This density can be adjusted by changing the thickness of the red lens.

Further, since the bulb mounting portion for mounting the bulb formed on the lamp body is located on the back side of the portion where the red lens and the side marker lens overlap, it is difficult to see through the lens.

〔Example〕

 An embodiment of the present invention will be described with reference to FIGS.

FIG. 6 is a front view of a rear combination lamp which is a vehicle lamp. The rear combination lamp shown in the figure is mounted on the right rear part of the vehicle, and it has a front lens area 16 for turn signal lamps, a front lens area 18 for tail and stop lamps, and a reflex reflector (hereinafter,
20), and side RR depending on the destination country
And lens 10 for side markers and dummy lenses
60 (Fig. 3) etc. are installed.

A sectional view taken along the line IV-IV in FIG. 6 is shown in FIG. The lamp body 22 of the rear combination lamp is integrally molded with resin, the reflector 24 is attached to the inner peripheral surface of the lamp body of the tail & stop lamp, and the inner peripheral surface of the lamp body of other lamps is coated with internal reflection coating. A reflective surface is formed. A seal groove 23 is provided around the front opening of the lamp body 22, and concave portions 28 and 30 are formed in the outer lens 26 that is engaged with and integrated with the seal groove 23. Lens for 10 and RR
20 mag is fitted. The outer lens 26 is amber in the front lens region 16 of the turn signal lamp and red in the other parts. At this time, since the light-shielding paint is applied to the back surface around the front lens area 16, red light is not emitted when the turn signal lamp is turned on. Large lamp room space formed by the lamp body 22
A valve 34 for a stop lamp is attached to 32, and a valve 38 for the side marker is attached to a small lamp chamber space 36. In addition, the lamp body 22 has these bulbs 3
A valve mounting portion 40 for mounting 4, 38 is formed. When a side marker lamp is required, a valve insertion hole for inserting the valve 38 is opened in the valve attachment portion 40. If the side RR and the side marker are not required to be attached, the valve insertion hole may remain closed. Therefore, the lamp body 22 may or may not be required.
Has the same shape except that the opening and closing of the bulb insertion hole is different, and the lamp body 22 is molded using the same lamp body molding die.

An end rubber 42 is applied to the rear side of the peripheral edge of the lamp body 22 so as to eliminate a gap with the vehicle body 43. Since the end rubber 42 is easily peeled off by its own repulsion, an end rubber guide 44 is formed inside the outer peripheral portion of the lamp body 22, as shown in FIG. 5 (A).
Support the end rubber 42 from the inner peripheral side. In order to weaken the repulsion of the end rubber 42 itself, for example, as shown in FIG. 5 (B), there is a method of forming a slit 46 on the inner peripheral side of the end rubber 42 at the corner portion of the peripheral edge portion of the lamp body where peeling easily occurs. By providing the end rubber guides 44 as described above, the repulsion can be weakened and peeling can be prevented.

As shown in FIG. 2, the concave portion 28 into which the lens 10 for the side RR and the side marker (hereinafter simply referred to as a lens) is fitted has a strip-shaped portion 48 at the center of the bottom which is a red lens. The other part 50 has been removed and opened. A diffusion step 52 is formed at a central strip-shaped portion of the lens 10, that is, a portion overlapping the part (strip-shaped portion) 48 left at the bottom of the outer lens to form a side marker portion. Steps 54 for reflecting the light from the outside are formed in other portions to form the side RR. A bulb mounting portion 40, which is integrally formed on the side of the lamp body 22 and for mounting the bulb 38 for the side marker, is located on the back side of the remaining strip-shaped portion 48 of the outer lens. As shown in FIG. 4, the valve 38 is inserted into the valve insertion hole of the valve attachment portion 40, and the portion of the strip-shaped portion 48 facing the valve 38 (see reference numeral 48a) interferes with the valve 38. It has a bent shape so as not to.

On the other hand, when the attachment of the side RR and the side marker is not required, the lens 10 for them is replaced by the outer lens 10 as shown in FIG. 3 and the outer lens 26 as shown in FIG. Dummy lens with the same fisheye step 58 as the formed step
60 is used. At this time, the bulb 38 for the side marker is not attached, and as the lamp body 22, a bulb attachment portion 40 having no bulb insertion hole is used.

The operation of this embodiment will be described below. First side
When the RR and the side marker are required to be mounted and the lens 10 for them is fitted, as shown in FIG. 1, a part (strip-shaped part) 48 left on the bottom of the concave part 28 is shown. Overlap the diffusion step 52 of the lens 10 (which becomes the lens for the side marker). Therefore, the light emitted from the side marker bulb 38 passes through the portion 48 left at the bottom of the concave portion 28 of the outer lens 26 and the lens 10, so that the red color becomes deep. Therefore, it is possible to prevent the red color of the light emitted from the side marker from becoming thinner as compared with the reflected light at the side RR as in the conventional case.

Further, when the dummy lens 60 shown in FIG. 3 is used, the unnecessary valve mounting portion 40 is the outer lens.
It can be hidden behind the part 48 left at the bottom of the concave part 28 of 26 and can be made difficult to see through from the outside through the lens. This can improve the appearance.

In this way, since there is no inconvenience even if the bulb mounting portion 40 for mounting the bulb 38 for the side marker is left in the lamp body 22, a common one is used as the lamp body 22, and the side RR and the side It can accommodate both when markers are required and when they are not.

[Effect of device]

As described above, according to the vehicular lamp of the present invention, the red lens on the back side of the side marker overlaps with the side marker, so that the side marker, which has been apt to become red in the past, emits red light. be able to.

Further, by arranging the bulb mounting portion on the back side of the portion where the red lens and the lens of the side marker overlap, this bulb mounting portion becomes difficult to see through the lens from the outside, and the appearance of the vehicular lamp is improved.
