Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle lamp equipped with a reflex reflector (hereinafter referred to as RR).

[Prior art]

Generally, some areas of tail lamps and tail & stop lamps are provided with RR to reflect light when it hits the vehicle from behind. this
Conventional vehicular lamps equipped with RR include those shown in FIGS. 7 to 9.

7 and 9 are front views of a combination lamp in which a tail and stop lamp 1a, a back-up lamp 1b, and a turn signal lamp 1c are integrated, respectively, and FIG. 8 is a cross-sectional view taken along the line - in FIG. 7. It is a diagram. In the case shown in FIGS. 7 and 8, a rectangular RR 6 is attached between the outer lens 2 and the inner lens 4. Note that numerals 5a to 5c are valves.

In the one shown in FIG. 9, a non-light-emitting region 15 surrounded by a shade 14 is formed in a part of the outer lens 12, and a part of this non-light-emitting region 15 is
An RR 16 is provided and integrated with the outer lens 12.

[Problem that the invention attempts to solve]

RR reflects light as it is, and this is the same on the back side of RR.When the lamp is lit, the RR forming area hardly emits light, and the conventional RR6 forming area and the non-light emitting area 15 where RR16 is provided do not.
It only functioned as an RR or a dummy section.

The present invention improves the RR section and RR section in the prior art.
This was done by focusing on the fact that the function of the non-light-emitting area where the RR part is formed is limited, and its purpose is to guide the bulb light to the RR part or the non-light-emitting area of the lens where the RR is provided. An object of the present invention is to provide a vehicular lamp which has a function of displaying characters, figures, etc.

[Means to solve the problem]

First, as a means to give the RR part a display function, in a vehicle lamp with an RR installed inside the lens, a light guide plate with stippled characters or figures etc. is placed between the lens and the RR. It was designed to do so.

In addition, as a means of providing a display function to an area other than the RR part of the non-emissive area of the lens, in a reflective type vehicle lamp that mainly illuminates using reflected light from a bulb, the light chamber space of the lamp body is shaded. In this vehicle lamp, a non-light-emitting region is formed in a lens arranged in front of the light chamber space, and a RR is provided in a part of the non-light-emitting region of the lens. Characters, figures, etc. are stippled and displayed in areas other than the RR portion of the light emitting area.

In addition, in direct-light type vehicle lamps that mainly illuminate with direct light from a bulb, the light chamber space of the lamp body is partitioned by a shade, and the inner lens placed in front of this light chamber space has a non-emitting light. In a vehicle lamp in which a region is formed and an RR is provided at a position opposite to this non-light emitting region of an outer lens disposed outside the inner lens, the region excluding the overlapped portion of the inner lens non-light emitting region with the RR This is a display in which letters, figures, etc. are displayed in stipples.

Furthermore, in direct-light type vehicle lamps, the light chamber space of the lamp body is partitioned by a shade.
A non-light emitting area is formed in the inner lens and outer lens placed in front of this lamp chamber space,
In a vehicle lamp in which a reflex reflector is provided in a part of the non-luminous area of the inner lens, characters, figures, etc. are stippled and displayed in the area other than the reflex reflector part of the non-luminous area of the inner lens. be.

[Effect]

In the vehicle lamp according to claim (1), when the lamp is turned on, the light guided by the light guide plate is reflected at the stippled display section, and the stippled display such as letters and figures stands out brightly from the RR forming area. Note that since light substantially perpendicular to the direction in which the light guide plate is disposed passes through the light guide plate, it does not affect the reflection effect of the RR.

In the vehicle lamp according to claims (2), (3), and (4), the bulb light is guided to the non-light emitting area of the lens (inner lens) by the light guiding action of the lens (inner lens), and the stipple display is performed. reflected at the
Stippled displays such as letters and figures stand out brightly.
