摘要： A vehicle light (1, 1A, 1B, 2, 2A, 2B, 3, 3A, 3B, 4, 4A, 4B) can prevent the color variations in the projected image. The vehicle light (1, 1A, 1B, 2, 2A, 2B, 3, 3A, 3B, 4, 4A, 4B) can include an LD (11), a wavelength conversion member (12, 22, 32, 42) including a phosphor (12, 22, 32, 42) configured to receive blue light having been emitted from the LD (11) and then emitting white light, and a reflector (13, 23, 33, 43) having a reflection surface (132, 231, 331, 431) that reflects the white light having been emitted from the wavelength conversion member (12, 22, 32, 42). The reflection surface (132, 231, 331, 431) of the reflector (13, 23, 33, 43) can have an optical structure (D, P, R) that can diffuse the blue light incident on the reflection surface from the phosphor (12, 22, 32, 42), reflect the blue light back to the phosphor (12, 22, 32, 42), or allow the blue light to pass through the reflection surface (132, 231, 331, 431) to the area rearward thereof.
