In this case, the detection unit 9 outputs the first detection signal to the control unit 90, and the control unit 90 outputs the first control signal to the high beam lamp unit 10. Then, the first semiconductor-type light source 21 and the second semiconductor-type light source 22 of the high beam lamp unit 10 are in an extinguished state, and the driving member 7 is in a stopped state. Thereby, as shown in FIG. 14, the high beam light distribution pattern is not irradiated in front of the vehicle C.

The In other words, the first diffused light distribution pattern WP1 of the first high beam light distribution pattern HP1 can illuminate a wide range up to the shoulder 15 on the opposite lane side, and the left vertical cut-off line CL4 emits nuisance light to the preceding vehicle 17. Further, the oncoming lane 14 can be illuminated far away by the first hot zone HZ1 of the first high beam light distribution pattern HP1, thereby contributing to safe driving.

  Then, as shown in FIG. 16, there is no preceding vehicle 17 in front of the vehicle C and there is an oncoming vehicle 18. In this case, the detection unit 9 outputs the third detection signal to the control unit 90, and the control unit 90 outputs the third control signal to the high beam lamp unit 10.

Further, the travel lane 13 can be illuminated far away by the second hot zone HZ2 of the second high beam light distribution pattern HP2, which can contribute to safe travel.

  And when there is no preceding vehicle 17 and the oncoming vehicle 18 ahead of the vehicle C, as shown in FIGS. In this case, the detection unit 9 outputs the fourth detection signal to the control unit 90, and the control unit 90 outputs the fourth control signal to the high beam lamp unit 10. Then, the first semiconductor light source 21 and the second semiconductor light source 22 of the high beam lamp unit 10 are controlled to be in a lighting state, and the driving member 7 is controlled to be in a driving state. As a result, as shown in FIG. 8, the light transmissive portion 611 of the first light control member 61 and the light transmissive portion 621 of the second light control member 62 that have been housed in the first housing groove portions 411 and 412 so far are The first semiconductor-type light source 21 and the second semiconductor-type light source 22 are positioned between the first main lens unit 310 and the second main lens unit 320.

For example, when the first semiconductor light source 21 is turned on and the first additional spot light distribution pattern SP1 and the second additional spot light distribution pattern SP2 are shielded, the first high beam light distribution pattern HP1 is irradiated. When the second semiconductor light source 22 is turned on and the first additional spot light distribution pattern SP1 and the second additional spot light distribution pattern SP2 are shielded, the second high beam light distribution pattern HP2 is irradiated. When the semiconductor light source 21 and the second semiconductor light source 22 are turned on and the first additional spot light distribution pattern SP1 and the second additional spot light distribution pattern SP2 are irradiated, a normal high beam light distribution pattern (first high beam) Light distribution pattern HP1 and first additional spot light distribution pattern SP1 and second high beam light distribution pattern HP And the second additional spot light distribution pattern SP2) is illuminated. As a result, a lens direct light distribution type lamp unit (semiconductor light source and direct light distribution) that irradiates the front of the vehicle with light from a semiconductor light source incident on the lens as a multi-function high beam light distribution pattern from the lens.

In the case of normal high beam light distribution patterns HP1, HP2, SP1, and SP2, the first hot zone HZ1 and the second hot zone HZ2 are separated from the first diffused light distribution pattern WP1 from the first lens 31 and the first hot light distribution pattern WP1. The second diffused light distribution pattern WP2 from the second lens 32 can be shifted toward the center of the diffused light distribution pattern superimposed (synthesized). Thereby, visibility improves and it can contribute to safe driving | running | working.
