  • Patent number: 11465554
    Abstract: Problem: To provide a light source unit that can be housed in a narrow space, can be curved to match the shape of the space, and can emit linear light in a desired lighting pattern, and a vehicle lamp equipped with this light source unit. Solution: A light source unit 1 is comprised of a strip of translucent film 3 in which LEDs 2 are embedded and strips of lenses 4 that cover the translucent film 3 on the top and back surfaces thereof. The lenses 4 are provided with a light collecting portion 41 that collects the light from the LEDs 2 and a reflective portion 42 that changes the direction of the light incident from the light collecting portion 41 on the surface opposite the surface on which the light collecting portion 41 is provided. The LEDs 2 are arranged linearly along the longitudinal direction of the translucent film 3, and each can be independently controlled for lighting.
