PROBLEM TO BE SOLVED: To achieve improvement of uniform light emission performance in a vehicle lamp fitting using a transparent material.SOLUTION: A vehicle lamp fitting 10 includes LEDs 22 and a first transparent material 23 for controlling light from the LEDs 22. The first transparent material 23 includes light guide elements 25, each of which includes: a first incident surface 27 which is located on an optical axis Ax of the LED 22 and allows a part of the light from the LED 22 to enter into the light guide element 25; a second right incident surface 28R which is located on a lateral side of the first incident surface 27 and allows a part of the light from the LED 22 to enter into the light guide element 25; a right reflection surface 29R which totally reflects the light entered from the second right incident surface 28R as diffused light; a first emission surface 30 which is located on the optical axis Ax of the LED 22 and emits the light entered from the first incident surface 27 to the outside; and a second right emission surface 31R which is located on a lateral side of the first emission surface 30, converts the light totally reflected by the right reflection surface 29R into parallel light, and emits the light to the outside.SELECTED DRAWING: Figure 1 |
