PROBLEM TO BE SOLVED: To solve problems in a conventional land vehicle mainly in an automobile lamp that, when LEDs are used as a light source especially for a tail lamp, a circuit board is twisted or distorted at curved parts of a vehicle, since the circuit board is constituted with the LEDs arrayed in parallel conventionally and illumination directions from the LEDs become uneven and the interference of light is caused, and highly accurate illumination cannot be obtained.SOLUTION: An automobile light device with LEDs arrayed is provided with a base plate, and in a central region of the base plate, there is formed a trapezoidal protruded part of a similar shape to an outer periphery of the base plate; LEDs are fitted in separation on the surrounding of the trapezoidal protruded part at proper distances; sidewall faces of the trapezoidal protruded part are made as inclined faces with smaller dimensions toward a tip end; and a top face of the trapezoidal protruded part is located at a higher position than an apex of the LEDs. |
