JP 2006-164909 A

  As a result, in the vehicular lamp 200 having the above-described configuration, when the main line is lit, a light distribution pattern suitable for a daytime running lamp can be formed (see FIG. 9), but a single reflecting surface 220 is provided. Since this is the optical axis AX (single rotation axis) (see FIG. 8), when the sub-line is turned on, light having a high intensity among the irradiation light from the sub-line is near the bulb light source 210 in the reflecting surface 220. The central luminous intensity is determined by the design so that the central luminous intensity is reflected on the central region of the light distribution pattern as a light beam L1 parallel to the rotation axis AX (optical axis) (see FIG. 8). It exceeds the luminous intensity (central maximum luminous intensity 60 cd × 80% = 48 cd determined in consideration of the standard maximum luminous intensity 60 cd determined by the standard and individual product variations) (see FIG. 10), and the front positioning lens It is impossible to form a light distribution pattern suitable for the flop It was found that.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a vehicular lamp that can switch between a light distribution pattern for a daytime running lamp and a light distribution pattern for a front positioning lamp. .

  In order to solve the above-mentioned problems, the invention according to claim 1 is directed to a vehicular lamp capable of switching between a daytime running lamp and a front positioning lamp, a bulb light source including a main line and a sub line, and a focal point of the bulb. A first parabolic surface of the rotary paraboloidal system set near the center of the light source and a paraboloidal system arranged on both sides of the first reflective surface and having a focal point set near the center of the bulb light source. A reflector including a second reflecting surface and a third reflecting surface of a paraboloidal surface system, and each of the second reflecting surface and the third reflecting surface has a rotational axis of the first reflecting surface. The first reflection surface, the second reflection surface, and the third reflection surface are respectively separated from the main line when the main line is lit. The reflected light is reflected, and the reflected light is When a composite light distribution pattern that satisfies the standard defined for the light distribution pattern for the time running lamp is formed and the sub-line is turned on, the irradiation light from the sub-line is reflected, and the reflected light is front-positioned. A synthetic light distribution pattern that satisfies a standard defined for the lamp light distribution pattern is formed.

  According to the first aspect of the invention, each of the first reflecting surface, the second reflecting surface, and the third reflecting surface reflects the irradiation light from the main line when the main line is lit, and the reflected light is Since it is configured to form a composite light distribution pattern that meets the standards specified for daytime running lamp light distribution patterns, when the main line is lit, a composite light distribution pattern suitable for daytime running lamps is used. It becomes possible to form.

  In addition, the second reflecting surface and the third reflecting surface are arranged in a state where the respective rotation axes are inclined inward by a predetermined angle with respect to the rotation axis of the first reflecting surface (that is, not a single optical axis but a composite optical axis). When the sub-line is turned on (because the first to third reflecting surfaces of the optical axis (composite rotation axis) are used), the light having a low luminous intensity out of the irradiation light from the sub-line is the second reflecting surface, A light distribution pattern is reflected as a light ray that is reflected by a reflection region away from the bulb light source in the third reflection surface and is parallel to the rotation axis (optical axis) of the second reflection surface and the rotation axis (optical axis) of the third reflection surface. The central area is irradiated. For this reason, when the sub-line is turned on, the central luminous intensity of the combined light distribution pattern can be reduced as compared with the case where the reflecting surface having a single optical axis is used.

  As a result, the central maximum luminous intensity required for designing the central luminous intensity of the light distribution pattern (central maximum luminous intensity determined in consideration of the standard maximum luminous intensity 60 cd determined by the standard and individual product variations = 60 cd × 80% = 48 cd). Therefore, it is possible to form a light distribution pattern suitable for a front positioning lamp.

  As described above, according to the first aspect of the present invention, it is possible to provide a vehicular lamp that can switch between a daytime running lamp and a front positioning lamp.

  According to a second aspect of the present invention, in the first aspect of the invention, the second reflective surface and the third reflective surface are part distributions formed by reflected light from the second reflective surface and the third reflective surface, respectively. The light pattern is configured to partially overlap in the central region.

  According to the second aspect of the present invention, the partial distribution light pattern formed by the reflected light from the second reflection surface and the third reflection surface partially overlaps in the central region, so the center of the combined light distribution pattern It is possible to prevent the luminous intensity from becoming smaller than the minimum central luminous intensity (see FIG. 7) determined by the standard of the front positioning lamp.

  According to a third aspect of the present invention, in the first aspect of the invention, the first reflecting surface reflects the irradiation light from the main line, and the reflected light is about 6 ° left and right with respect to the vertical axis. It is configured to form a partial distribution light pattern in a rectangular range of about 12 ° up and down with respect to the horizontal axis, the second reflecting surface reflects the irradiation light from the main line, and the reflected light is A partial distribution light pattern is formed in a rectangular range of about 22.5 ° to the right with respect to the vertical axis, about 2.5 ° to the left and about 7.5 ° up and down with respect to the horizontal axis. The third reflecting surface reflects the irradiation light from the main line, and the reflected light is about 22.5 ° to the left with respect to the vertical axis, about 2.5 ° to the right, and about 7.5 up and down with respect to the horizontal axis. The partial light distribution pattern is formed in a rectangular range of 0 °.

  According to the third aspect of the present invention, when the main line is lit on the first reflecting surface, the second reflecting surface, and the third reflecting surface, the irradiation light from the main line is reflected, and the reflected light is By constructing a synthetic light distribution pattern that meets the standard defined for the light distribution pattern for time-running lamps, the center maximum luminous intensity (specified by the standard) required for design when the secondary line is lit is established. It is possible to form a light distribution pattern suitable for a front positioning lamp that does not exceed the maximum central luminous intensity of 60 cd × 80% = 48 cd) determined in consideration of the obtained central maximum luminous intensity of 60 cd and individual product variations. In addition, it becomes possible to provide a vehicular lamp.

  According to the present invention, it is possible to provide a vehicular lamp using a semiconductor light source capable of switching between a high beam light distribution pattern and a daytime running lamp light distribution pattern.

The surface 11 may be smoothly continuous without a step (for example, when the F value of the second reflective surface 12 is adjusted so as to be smoothly continuous with the first reflective surface 11).

  The third reflecting surface 13 is a rotating paraboloid reflecting surface whose focal point is set in the vicinity of the center of the bulb light source 20, and its rotation axis AX3 is the rotation axis of the first reflecting surface 11, as shown in FIG.

In the upper rectangular range (rectangular range of about 22.5 ° to the left with respect to the vertical axis V-V, about 2.5 ° to the right, and about 7.5 ° up and down with respect to the horizontal axis H-H. See FIG. 4) The partial distribution light pattern P3 is configured (designed).

  In addition, the 3rd reflective surface 13 may be following the 1st reflective surface 11 via the level | step difference (for example, when the F value of the 3rd reflective surface 13 and the 1st reflective surface 11 is the same), or a 1st reflective surface The surface 11 may be smoothly continuous without a step (for example, when the F value of the third reflective surface 13 is adjusted so as to be smoothly continuous with the first reflective surface 11).

  As shown in FIG. 1, the bulb light source 20 is a so-called double filament bulb light source including a main line 21 (for example, a light beam 440 lm) and a sub-line 22 (for example, a light beam 35 lm). The bulb light source 20 is inserted into the opening 11 a formed in the first reflecting surface 11 from the back side of the first reflecting surface 11 and is disposed on the reflecting surface 11 side.

  Next, a light distribution pattern formed by the vehicular lamp 100 having the above configuration will be described.

  When the bulb light source 20 (main line 21) is turned on, as shown in FIG. 1, the irradiation light Ray1 from the bulb light source 20 (main line 21) that has reached the first reflection surface 11 is transmitted through the first reflection surface 11. A rectangular range on the vertical screen S that is reflected and irradiated as a light beam parallel to the rotation axis AX1 of the first reflecting surface 11 (about 6 ° to the left and right with respect to the vertical axis V-V, horizontal axis) The partial light distribution pattern P1 is formed in a rectangular range of about 12 ° up and down with respect to HH (see FIG. 4).

  Further, the irradiation light Ray2 from the bulb light source 20 (main line 21) that has reached the second reflecting surface 12 is reflected by the second reflecting surface 12 and irradiated as a light beam parallel to the rotation axis AX2 of the second reflecting surface 12. And a rectangular range on the vertical screen S installed 10 m ahead (about 22.5 ° to the right with respect to the vertical axis VV, about 2.5 ° to the left, about 7 ° up and down with respect to the horizontal axis HH). The partial light distribution pattern P2 is formed in a rectangular range of 5 ° (see FIG. 4).

  Further, the irradiation light Ray3 from the bulb light source 20 (main line 21) that has reached the third reflecting surface 13 is reflected by the third reflecting surface 13 and irradiated as a light beam parallel to the rotation axis AX3 of the third reflecting surface 13. And a rectangular area on the vertical screen S installed in front of 10 m (about 22.5 ° to the left with respect to the vertical axis VV, about 2.5 ° to the right, about 7 to up and down with respect to the horizontal axis HH). The partial light distribution pattern P3 is formed in a rectangular range of 5 ° (see FIG. 4).

Thus, the combined light distribution pattern PDRL including the partial distribution light patterns P1 to _P3 is formed (see FIG. 4). Referring to FIGS. 4, 5, the synthesized light distribution pattern P _DRL is, day time running lamp light distribution pattern standard minimum luminous intensity required for each measurement point defined by (ECE Reg87) (see FIG. 5) It can be seen that

  On the other hand, when the bulb light source 20 (secondary line 22) is turned on, as shown in FIG. 1, the irradiation light Ray1 from the bulb light source 20 (secondary line 22) reaching the first reflecting surface 11 is the first light ray. A rectangular area on the vertical screen S (approx. 6 on the left and right sides with respect to the vertical axis V-V) that is reflected by the reflecting surface 11 and irradiated as a light beam parallel to the rotation axis AX1 of the first reflecting surface 11 The partial light distribution pattern P4 is formed in a rectangular range of about 12 ° up and down with respect to the horizontal axis HH (see FIG. 6).

  Further, the irradiation light Ray2 from the bulb light source 20 (sub-line 22) that has reached the second reflecting surface 12 is reflected by the second reflecting surface 12 and is a light beam parallel to the rotation axis AX2 of the second reflecting surface 12. A rectangular area on a vertical screen S that is irradiated and placed 10 m in front (about 22.5 ° to the right with respect to the vertical axis VV, about 2.5 ° to the left, about 7 to the top and bottom with respect to the horizontal axis HH) A partial light distribution pattern P5 is formed in a rectangular range of 5 ° (see FIG. 6).

Since the second reflecting surface 12 is arranged with its rotation axis AX2 inclined inward by 10 ° with respect to the rotation axis AX1 of the first reflecting surface 11 (see FIG. 1), the bulb light source 20 (subline 22). Is turned on, the light Ray2 _Lo having a low luminous intensity out of the irradiation light from the bulb light source 20 (sub-line 22) is reflected by the reflection region 12a away from the bulb light source 20 in the second reflecting surface 12 (see FIG. 1 reference), and thus irradiated to the central region _{P5 Low} of the second combined light distribution pattern _{P FP} as ray parallel to the rotational axis AX2 (optical axis) of the reflecting surface 12 (see FIG. 6). Therefore, when lighting the bulb light source 20 (sub-line 22), when using a reflecting surface of the single optical axis compared to (see FIG. 8), reducing the central luminous intensity of the synthesized light distribution pattern P _FP Is possible.

As a result, the central luminous intensity exceeds the central maximum luminous intensity required by design (central maximum luminous intensity determined in consideration of the standard maximum luminous intensity 60 cd determined by the standard and individual product variations = 60 cd × 80% = 48 cd). It is possible to form a composite light distribution pattern P _FP (see FIG. 6) suitable for a front positioning lamp.

Of the light emitted from the bulb light source 20 (subline 22), the light Ray2 _Hi having a high intensity is reflected by the reflection region 12b in the vicinity of the bulb light source 20 in the second reflecting surface 12 (see FIG. 1). to be irradiated to the region P5 _high shifted outwardly from the central region of the synthesized light distribution pattern P _FP as ray parallel to the rotational axis AX2 (optical axis) of the second reflecting surface 12 (see FIG. 6), synthesized light distribution pattern Almost no influence on the central intensity of _PFP .

  Further, the irradiation light Ray3 from the bulb light source 20 (subline 22) that has reached the third reflecting surface 13 is reflected by the third reflecting surface 13 and is a light beam parallel to the rotation axis AX3 of the third reflecting surface 13. A rectangular area on a vertical screen S which is irradiated and placed in front of 10 m (about 22.5 ° to the left with respect to the vertical axis VV, about 2.5 ° to the right, about 7 up and down with respect to the horizontal axis HH) A partial light distribution pattern P6 is formed in a rectangular range of 5 ° (see FIG. 6).

Since the third reflecting surface 13 is arranged with its rotation axis AX3 inclined inward by 10 ° with respect to the rotation axis AX1 of the first reflecting surface 11 (see FIG. 1), the bulb light source 20 (subline 22). Is turned on, the light Ray3 _Lo having a low luminous intensity out of the light emitted from the bulb light source 20 (sub-line 22) is reflected by the reflection region 13a far from the bulb light source 20 in the third reflecting surface 13 (FIG. 1 reference), and thus irradiated to the central region _{P6 Low} of the third combined light distribution pattern _{P FP} as light rays parallel to the rotation axis AX3 (optical axis) of the reflecting surface 13 (see FIG. 6). Therefore, when lighting the bulb light source 20 (sub-line 22), when using a reflecting surface of the single optical axis compared to (see FIG. 8), reducing the central luminous intensity of the synthesized light distribution pattern P _FP Is possible.

As a result, the central luminous intensity exceeds the central maximum luminous intensity required by design (central maximum luminous intensity determined in consideration of the standard maximum luminous intensity 60 cd determined by the standard and individual product variations = 60 cd × 80% = 48 cd). It is possible to form a composite light distribution pattern _PFP suitable for a front positioning lamp.

Of the light emitted from the bulb light source 20 (subline 22), the light Ray3 _Hi having a high intensity is reflected by the reflection region 13b in the vicinity of the bulb light source 20 in the third reflecting surface 13 (see FIG. 1). to be irradiated to the rotating shaft AX3 region P6 shifted outwardly from the central region of the synthesized light distribution pattern P _FP as ray parallel to the (optical axis) _High of the third reflection surface 13 (see FIG. 6), synthesized light distribution pattern Almost no influence on the central intensity of _PFP .

Thus, synthesized light distribution pattern _{P DRL} containing partial light distribution pattern P4~P6 is formed (see FIG. 6). Figure 6 Referring to Figure 7, the synthesized light distribution pattern P _DRL is the standard for the light distribution pattern for the front positioning ramp minimum intensity required for each measurement point defined by (ECE REG7) (see FIG. 7) You can see that it meets.

In order to prevent the central luminous intensity of the combined light distribution pattern _PFP from becoming smaller than the central minimum luminous intensity (see FIG. 7) defined in the standard, the second reflective surface 12 and the third reflective surface 13 are respectively The partial distribution light patterns P5 and P6 formed by the reflected light from the second reflecting surface 12 and the third reflecting surface 13 are configured (designed) so as to partially overlap in the central region (see FIG. 6).

As described above, according to the vehicular lamp 100 of the present embodiment, the first reflecting surface 11, the second reflecting surface 12, and the third reflecting surface 13 are each when the bulb light source 20 (main line 21) is lit. Is configured to reflect the light emitted from the main bulb light source 20 (main line 21), and the reflected light forms a combined light distribution pattern _PDRL that satisfies the standards defined for the daytime running lamp light distribution pattern. Therefore, when the bulb light source 20 (main line 21) is turned on, a light distribution pattern P _DRL (see FIG. 4) suitable for a daytime running lamp can be formed.

Further, the second reflecting surface 12 and the third reflecting surface 13 are arranged in a state in which the respective rotation axes AX2 and AX3 are inclined inward by 10 ° with respect to the rotation axis AX1 of the first reflecting surface 11 (that is, simply). When the bulb light source 20 (subline 22) is turned on because the reflecting surfaces 11 to 13 of the compound optical axes AX1 to AX3 are used instead of one optical axis, the light from the bulb light source 20 (subline 22) Lights Ray2 _Lo and Ray3 _Lo having low luminous intensity among the irradiated light are reflected by the reflection areas 12a and 13a away from the bulb light source 20 among the second reflection surface 12 and the third reflection surface 13 (see FIG. 1). The central areas P5 _Low and P6 _Low of the light distribution pattern are irradiated as light rays parallel to the rotation axis AX2 (optical axis) of the second reflection surface 12 and the rotation axis AX3 (optical axis) of the third reflection surface 12 ( (See FIG. 6). Therefore, when lighting the bulb light source 20 (sub-line 22), when using a reflecting surface of the single optical axis compared to (see FIG. 8), reducing the central luminous intensity of the synthesized light distribution pattern P _FP Is possible.

As a result, the central luminous intensity exceeds the central maximum luminous intensity required by design (central maximum luminous intensity determined in consideration of the standard maximum luminous intensity 60 cd determined by the standard and individual product variations = 60 cd × 80% = 48 cd). It is possible to form a light distribution pattern P _FP (see FIG. 6) suitable for a front positioning lamp.

  As described above, according to the vehicular lamp 100 of the present embodiment, the daytime running lamp and the front positioning lamp can be switched.

Further, according to the vehicular lamp 100 of the present embodiment, the partial distribution light patterns P5 and P6 formed by the reflected light from the second reflecting surface 12 and the third reflecting surface 13 partially overlap in the central region. Therefore (see FIG. 6), it is possible to prevent the central luminous intensity of the combined light distribution pattern _PFP from becoming smaller than the minimum central luminous intensity (see FIG. 7) defined by the standard of the front positioning lamp.

Further, according to the vehicular lamp 100 of the present embodiment, when the main line 21 is lit on the first reflecting surface 11, the second reflecting surface 12, and the third reflecting surface 13, the irradiation light from the main line 21 is reflected. When the sub-line 22 is turned on by configuring the reflected light so as to form a synthetic light distribution pattern _PDRL that satisfies the standard (see FIG. 5) defined for the light distribution pattern for daytime running lamps. Furthermore, the central luminous intensity does not exceed the central maximum luminous intensity required by design (central maximum luminous intensity determined in consideration of the standard maximum luminous intensity 60 cd determined by the standard and individual product variations = 60 cd × 80% = 48 cd). In addition, it is possible to provide the vehicular lamp 100 capable of forming the light distribution pattern _PFP suitable for the front positioning lamp.

  Next, a modified example will be described.

In the above embodiment, in order to prevent the central luminous intensity of the combined light distribution pattern _PFP from becoming smaller than the minimum central luminous intensity (see FIG. 7) defined by the standard, a part of the partial distribution light patterns P5 and P6 is centered. Although an example of overlapping in a region has been described, the present invention is not limited to this.

For example, if the central light intensity of the combined light distribution pattern _PFP can satisfy the minimum center light intensity (see FIG. 7) defined by the standard, the partial light distribution patterns P5 and P6 need not be superimposed.

  In the above embodiment, the example in which the rotation axes AX2 and AX3 of the second reflection surface 12 and the third reflection surface 13 are inclined 10 ° inside with respect to the rotation axis AX1 of the first reflection surface 11 has been described. The present invention is not limited to this. For example, the angle may be around 10 ° or any other angle.

  The above embodiment is merely an example in all respects. The present invention is not construed as being limited to these descriptions. The present invention can be implemented in various other forms without departing from the spirit or main features thereof.
