Definitions

  • the present disclosure relates to a vehicle lamp and a vehicle lamp system.
  • the light distribution pattern has high beam HB and low beam LB.
  • the high beam HB is irradiated in the range of about +3.8° to -3.6° in the V direction (vertical direction) in the drawing and in the range of about ⁇ 14.4° in the H direction in the drawing.
  • This high beam HB is formed by the first laser beam L1 that irradiates the second region 32 of the phosphor plate 18 .
  • such a light distribution pattern can be realized by switching on and off during scanning with the first laser light L1. .
  • the low beam LB is irradiated in the range of 0° to about -7.5° in the V direction in the figure and in the range of about ⁇ 19.4° in the H direction in the figure. Comparing the irradiation range in the H direction, the low beam LB is wider than the high beam HB. Also, comparing the irradiation range in the V direction, the low beam LB and the high beam HB are almost the same.
  • This low beam LB is formed by the second laser beam L2 with which the first region 31 of the phosphor plate 18 is irradiated. As shown, the high beam HB partially overlaps the low beam LB.
  • Such a light distribution pattern is realized by lens design of the projection lens 19 .
  • the distance Dr of the optical path leading to the phosphor plate 18 via the first scanning mirror 12 and the first brightness correction lens 13, which are relatively arranged on the upper side of the lamp unit 1, needs to be shortened.
  • the distance Db of the optical path leading to the phosphor plate 18 via the second scanning mirror 16 and the second brightness correcting lens 17 can be easily secured.
