LED BULB AND LED BULB UNIT

To provide an LED bulb in consideration of the safety of pedestrians.SOLUTION: An LED bulb 1 is used for a vehicular headlight, and has a first LED substrate 4, a second LED substrate 5, and a support 6 that supports the first and second LED substrate 4, 5. The first LED substrate 4 has a first light source 42 that emits light for irradiating the on-coming lane side, and a first printed wiring board 41 with the first light source 42 mounted thereon. The first light source 42 has at least one LED. The second LED substrate 5 has a second light source 52 that emits light for irradiating the sidewalk side, and a second printed wiring board 51 with the second light source 52 mounted thereon. The second light source 52 has at least one LED. The second light source 52 has a brightness higher than that of the first light source 42.SELECTED DRAWING: Figure 2 【課題】歩行者の安全性を考慮したＬＥＤバルブを提供する。【解決手段】ＬＥＤバルブ１は、車両用前照灯で用いられるものであって、第１ＬＥＤ基板４と、第２ＬＥＤ基板５と、第１及び第２ＬＥＤ基板４，５を支持する支持体６と、を備える。第１ＬＥＤ基板４は、対向車線側を照射するための光を発する第１光源４２と、第１光源４２が実装された第１プリント配線基板４１と、を有し、第１光源４２は少なくとも１個のＬＥＤを有し、第２ＬＥＤ基板５は、歩道側を照射するための光を発する第２光源５２と、前記第２光源５２が実装された第２プリント配線基板５１と、を有し、第２光源５２は少なくとも１個のＬＥＤを有し、第２光源５２の輝度は第１光源４２の輝度より高い。【選択図】図２
