Hereinafter, a mode for carrying out the vehicle lamp of the present invention will be described with reference to the accompanying drawings.

The embodiment shown below is an application of the vehicle lamp of the present invention to a turn signal lamp. The present invention is widely applied to various vehicle lighting fixtures such as tail lamps, clearance lamps, stop lamps, daytime running lamps, cornering lamps, hazard lamps, position lamps, back lamps, fog lamps or combination lamps which are combinations thereof. can do.

In the following description, the direction of irradiating the outside of the light is set to the rear, and the directions of front, back, up, down, left and right are shown. However, the front-back, up-down, left-right directions shown below are for convenience of explanation, and the practice of the present invention is not limited to these directions.

For example, the vehicle lighting fixture 1 is attached and arranged at both left and right ends of the vehicle body. The vehicle lamp 1 includes a lamp housing 2 having a recess opened rearward and a cover 3 that closes the opening of the lamp housing 2 (see FIG. 1). The lamp housing 2 and the cover 3 constitute a lamp outer housing 4. The internal space of the lamp outer casing 4 is formed as a lamp chamber 5.

In the lamp chamber 5, for example, the first lamp unit 6 and the second lamp unit 7 are arranged side by side on the left and right. The first lamp unit 6 is located inside the vehicle, and the second lamp unit 7 is located outside the vehicle.

The first lamp unit 6 is mounted on a lamp case 8 opened rearward, a cover lens 9 for closing the opening of the lamp case 8, and a substrate 10 and a substrate 10 located on the front side of the lamp case 8 so as to face in the front-rear direction. It has light sources 11, 11, ...

The lamp case 8 has a base surface portion 12 facing in the front-rear direction and a peripheral surface portion 13 projecting rearward from the outer peripheral portion of the base surface portion 12. Through holes 12a, 12a, ... Are formed in the base surface portion 12 so as to be separated from each other on the left and right. The rear surface of the base surface portion 12 and the inner peripheral surface of the peripheral surface portion 13 may be formed as reflective surfaces.

The cover lens 9 is formed with, for example, a lens step (not shown) for diffusing light and the like.

The substrate 10 is attached to the front surface of the base surface portion 12, for example. The light sources 11, 11, ... Are mounted on the rear surface of the substrate 10 at a distance from each other to the left and right. The light sources 11, 11, ... Are arranged in the transmission holes 12a, 12a, ... In a state where the substrate 10 is attached to the base surface portion 12, respectively.

The second lamp unit 7 has the same configuration as the first lamp unit 6, and includes a lamp case 8, a cover lens 9, a substrate 10, light sources 11, 11, ....

For example, six light sources 11, 11, ... Of the first lamp unit 6 are provided, and three light sources 11, 11, 11 located inside in the vehicle are provided as the first light emitting unit 14. The three light sources 11, 11, 11 located on the outside of the vehicle are provided as the second light emitting unit 15.

For example, six light sources 11, 11, ... Of the second lamp unit 7 are provided, and three light sources 11, 11, 11 located inside in the vehicle are provided as the third light emitting unit 16. The three light sources 11, 11, and 11 located on the outside of the vehicle are provided as the fourth light emitting unit 17.

In the vehicle lamp 1, two adjacent light emitting units are provided as adjacent light emitting bodies. Therefore, the first light emitting unit 14 and the second light emitting unit 15 constitute the first adjacent light emitting body 18, and the second light emitting unit 15 and the third light emitting unit 16 form the second adjacent light emitting body 19. Then, the third light emitting unit 16 and the fourth light emitting unit 17 form a third adjacent light emitting body 20.

In the vehicle lamp 1 configured as described above, light is emitted from the light sources 11, 11, 11 of the first light emitting unit 14 at the same time, and light is simultaneously emitted from the light sources 11, 11, 11 of the second light emitting unit 15. Is emitted, light is emitted from the light sources 11, 11 and 11 of the third light emitting unit 16 at the same time, and light is emitted from the light sources 11, 11 and 11 of the fourth light emitting unit 17 at the same time. Further, in the first light emitting unit 14, the second light emitting unit 15, the third light emitting unit 16, and the fourth light emitting unit 17, the light emitting points are changed in order and the sequential light emitting state is visually recognized so that the light flows. Light is emitted from the first light emitting unit 14 in order with a time lag so that 17 is lit.

The light sources 11, 11, ... Are turned on after a certain period of time and then turned off. Such point-off control of the light sources 11, 11, ... Is performed by the control circuit 50. Therefore, the control circuit 50 also controls the sequential light emission state.

When light is emitted from the light source 11, the emitted light is incident on the cover lens 9 through the transmission hole 12a, diffused by the cover lens 9, passed through the cover 3, and is irradiated backward.

At this time, a part of the light emitted from the light sources 11, 11 and 11 of the second light emitting unit 15 reaches the peripheral surface portion 13 of the lamp case 9 in the first lamp unit 6 and goes to the third light emitting unit 16 side. Progress is blocked. Similarly, a part of the light emitted from the light sources 11, 11, 11 of the third light emitting unit 16 reaches the peripheral surface portion 13 of the lamp case 9 in the second lamp unit 7, and the second light emitting unit 15 Progress to the side is blocked.

Therefore, the portion of the peripheral surface portion 13 of the first lamp unit 6 located on the second lamp unit 7 side and the peripheral surface portion 13 of the second lamp unit 7 located on the first lamp unit 6 side. The portion functions as a light-shielding portion 21 that blocks the progress of light.

In the vehicle lamp 1, as described above, the first light emitting unit 14, the second light emitting unit 15, the third light emitting unit 16, and the fourth light emitting unit 17 are lit in order. At this time, the emission start times of adjacent light emitting units are set as follows.

A light-shielding unit 21 is not provided between the two light-emitting units. The difference in emission start time between the two light-emitting units in an adjacent light emitting body is defined as the first time difference, and the light-shielding unit 21 is provided between the two light-emitting units. Assuming that the difference between the emission start times of the two light emitting portions in the adjacent light emitting bodies is the second time difference, the second time difference is smaller than the first time difference.

Therefore, the difference between the emission start times of the first light emitting unit 14 and the second light emitting unit 15 and the difference between the emission start times of the third light emitting unit 16 and the fourth light emitting unit 17 are regarded as the first time difference. The difference between the emission start times of the second light emitting unit 15 and the third light emitting unit 16 is defined as the second time difference, and the second time difference is 20% to 40% smaller than the first time difference.

Specifically, the first time difference between the first light emitting unit 14 and the second light emitting unit 15 is set to, for example, 54 msec, and the second time difference between the second light emitting unit 15 and the third light emitting unit 16 is set. For example, the time difference between the third light emitting unit 16 and the fourth light emitting unit 17 is set to 36 msec, and the first time difference between the third light emitting unit 16 and the fourth light emitting unit 17 is set to 54 msec, for example.

When an adjacent light emitting unit in which a light shielding unit 21 is not provided between the two light emitting units, for example, the first light emitting unit 14 and the second light emitting unit 15 of the first adjacent light emitting body 18 are turned on in order, the first light emitting unit is lit. A part of the light emitted from the light emitting unit 14 of 1 travels to the side of the second light emitting unit 15, and the second light emitting unit 15 is lit before the second light emitting unit 15 is turned on by the viewer. It is recognized as if you are doing it. This phenomenon is the same in the third adjacent illuminant 20.

On the other hand, when the second light emitting unit 15 and the third light emitting unit 16 of the second adjacent light emitting body 19, which is an adjacent light emitting body in which the light emitting unit 21 is provided between the two light emitting units, are turned on in order, As described above, the progress of the light emitted from the second light emitting unit 15 toward the third light emitting unit 16 is blocked. Therefore, the viewer does not recognize that the third light emitting unit 16 is lit before the third light emitting unit 16 is lit.

As described above, the lighting state of the adjacent illuminant in which the light-shielding portion 21 is not provided between the two light-emitting portions and the adjacent illuminant in which the light-shielding portion 21 is provided between the two light-emitting portions are different for the viewer. Is recognized as. Therefore, as described above, by making the second time difference smaller than the first time difference, the viewer can see the first light emitting unit 14, the second light emitting unit 15, the third light emitting unit 16, and the fourth light emitting unit. It is recognized that the units 17 are lit in order with the same time difference.

As described above, in the vehicle lamp 1, the difference in the emission start time of the two light emitting parts in the adjacent light emitting body in which the light emitting part 21 is not provided between the two light emitting parts is defined as the first time difference. , When the difference in the emission start time of the two light emitting parts in the adjacent light emitting body in which the light shielding part 21 is provided between the two light emitting parts is set as the second time difference, the second time difference is larger than the first time difference. It has been made smaller.

Therefore, the difference in the emission start time of the two light emitting units in the adjacent light emitting body in which the light emitting unit 21 is provided between the two light emitting units is the difference between the adjacent light emitting units in which the light emitting unit 21 is not provided between the two light emitting units. Since it is smaller than the difference between the emission start times of the two light emitting parts in the body, it is perceived by the viewer that the lighting of the light emitting parts is performed in order at equal intervals, and the visibility is improved. be able to.

Further, since the second time difference is reduced by 20% to 40% with respect to the first time difference, the ratio of the second time difference to the first time difference is set to 60% to 80%, and all adjacent light emission is emitted. It is recognized that the difference in the emission start time between the parts is sensuously substantially uniform, and high visibility can be ensured.

Further, since the light emitting units 14, 15, 16 and 17 are each composed of a plurality of light sources 11, light is emitted from each of the plurality of light sources 11 in the light emitting units 14, 15, 16 and 17, to improve the brightness. In addition, visibility can be improved.

Furthermore, a first lamp unit 6 and a second lamp unit 7 each having a light emitting unit are provided, and a control circuit 50 for controlling turning on and off of all the light emitting units 14, 15, 16 and 17 is provided. ..

Therefore, since the lighting of all the light emitting units 14, 15, 16 and 17 is controlled by the control circuit 50, the lighting of all the light emitting units can be controlled by the minimum number of control circuits, and the manufacturing cost. Can be reduced.

Further, since the first lamp unit 6 and the second lamp unit 7 have the same configuration, the first lamp unit 6 and the second lamp unit 7 do not require different parts for each vehicle. The manufacturing cost of the lamp 1 can be reduced.

In addition, although the example in which two lamp units of the first lamp unit 6 and the second lamp unit 7 are provided is shown above, the number of lamp units is arbitrary, and one lamp unit may be used. It may be three or more. Even in this case, these lamp units may have the same configuration. Further, although an example in which four light emitting parts are provided is shown above, the number of light emitting parts is arbitrary as long as it is three or more. Further, although an example in which one light emitting unit is composed of three light sources 11 is shown above, the number of light sources constituting the light emitting unit is arbitrary and may be one or two. It may be one or more.

In the above description, the vehicle lamp 1 having a configuration in which the light emitted from the light sources 11, 11, ... Is irradiated as direct light without being reflected or guided has been described as an example. It is also possible to apply the light to the vehicle lamp 1A that reflects and irradiates the light and the vehicle lamp 1B that guides and irradiates the light (see FIGS. 2 to 4).

Since the vehicle lamps 1A and 1B shown below differ only in the configuration of the lamp unit as compared with the vehicle lamp 1 described above, only the parts different from the vehicle lamp 1 are detailed. The other parts will be given the same reference numerals as those given to the same parts in the vehicle lamp 1, and the description thereof will be omitted.

It is lit.

The light sources 11, 11, ... Are turned on and off by a control circuit (not shown).

The vehicle lamp 1A may be provided with an optical control lens that diffuses light between the reflecting portion 23 and the cover 3.

When light is emitted from the light source 11, the emitted light is reflected by the reflecting surface 23a of the reflecting unit 23, is transmitted through the cover 3, and is irradiated backward.

At this time, a part of the light emitted from the light source 11 of the second light emitting unit 15A reaches the end portion of the reflecting unit 23 of the first lamp unit 6A on the second lighting unit 7A side, and the third light emitting unit 16A Progress to the side is blocked. Similarly, a part of the light emitted from the light source 11 of the third light emitting unit 16A reaches the end portion of the reflecting unit 23 of the second lamp unit 7A on the first lamp unit 6A side, and the second lamp unit 7A has a second.

The portion functions as a light-shielding portion 21A that blocks the progress of light.

It is recognized that they are lit in order with the same time difference.

In the above, an example in which the light-shielding portion 21B is arranged between the first lamp unit 6B and the second lamp unit 7B has been shown. For example, the light guide portions 24a and 24a in the light guide bodies 24 and 24 have been shown. By forming each of the opposite end faces of the above as a total reflection surface, it is possible to block light in the same manner as the light-shielding portion 21B. Further, it is also possible to block light in the light guide bodies 24 and 24 in the same manner as the light shielding portion 21B by applying metal vapor deposition or the like to the opposite end faces of the light guide portions 24a and 24a.

In these cases, since it is not necessary to provide the light-shielding portion 21B, it is possible to reduce the number of parts of the vehicle lamp 1B and simplify the structure.

In the above, an example in which one vehicle lamp is provided with three or more light emitting units is shown, but the present invention has a configuration in which a plurality of vehicle lamps are provided with three or more light emitting units as a whole. Can also be applied (see FIG. 5).

As such an example, there is a configuration in which one vehicle lighting device 1C is arranged in a fixed portion of the vehicle and the other vehicle lighting device 1C is arranged in a movable portion of the vehicle, for example, a trunk lid.

In this case, a control circuit for controlling the lighting of the light emitting portion of one vehicle lighting tool 1C and a control circuit for controlling the lighting of the light emitting portion of the other vehicle lighting tool 1C are separately required.
