PROBLEM TO BE SOLVED: To ensure safety for vehicle running, by achieving a vehicular lamp equipment system that can detect a presence of an object even in a light distribution area where lamp light is reduced or out.SOLUTION: Vehicular lamp equipment comprises: a light-emitting part having a plurality of light-emitting channels with a first light-emitting element that emits light of first spectrum and a second light-emitting element that emits light of second spectrum; and a light-emitting drive circuit having a voltage conversion part that generates drive voltage for lighting on the light-emitting elements in the light-emitting part by receiving DC voltage and converting the voltage, and a lighting on/off control part that controls lighting on/off of the light-emitting elements based on drive voltage. The area where light is distributed by the first light-emitting element and the area where light is distributed by the second light-emitting element overlap in each light-emitting channel at least partly. Light emitted from the light-emitting element in each light-emitting channel is emitted ahead of the lamp equipment. In selective light-reduction control in which the first light-emitting element of the light-emitting channel specified among the first light-emitting elements lighted on is reduced in light or lighted off, the second light-emitting element in the specified light-emitting channel is lighted on.SELECTED DRAWING: Figure 4

    【課題】減光又は消灯状態とした配光領域についても対象物の存在を検知可能な車両用灯具システムを実現し、車両運行上の安全性確保が図られるようにする。【解決手段】第一のスペクトルを有する光を発する第一発光素子と第二のスペクトルを有する光を発する第二発光素子とを有する発光チャンネルを複数有する発光部と、直流電圧を受け電圧変換を行って発光部における発光素子を点灯させるための駆動電圧を生成する電圧変換部と、駆動電圧に基づく発光素子の点消灯制御を行う点消灯制御部とを有する発光駆動回路とを備え、各発光チャンネルにおいて第一発光素子による配光領域と第二発光素子による配光領域が少なくとも一部重複し、各発光チャンネルにおける発光素子からの光を灯具前方に照射する車両用灯具であって、点消灯制御部は、点灯状態の第一発光素子のうち指示された発光チャンネルの第一発光素子を減光又は消灯させる選択減光制御において、指示された発光チャンネルにおける第二発光素子を点灯させる。【選択図】図4
