Document Type and Number:
Japanese Patent JP6132684
Kind Code:
B2
Abstract:
The present invention relates to a lamp used for a vehicle, comprising: a light source (10); a light distribution pattern forming part (30) formed by arranging a plurality of optical elements; and an optical component (20) which irradiates light of the light source to the light distribution pattern forming part (30). The optical component (20) iirradiates light of the light source to the light distribution pattern forming part (30), so that specific illuminance distribution comprising a first illuminance region (R1) and a second illuminance region (R2) having lower illuminance is formed. The light distribution pattern forming part (30) utilizes the optical elements which are overlapped with the first illuminance region (R1) to irradiate the lights used for forming a specific first light distribution pattern, and utilizes the optical elements which are overlapped with the second illuminance region (R2) to irradiate the lights used for forming a second light distribution pattern having lower illuminance, or enables the optical elements which are overlapped with the second illuminance region to be in a non-irradiating state.
