Claims

[Scope of utility model registration request]

In an LED lamp for a vehicle, the light source is LED lamps arranged in a plurality of rows or columns, and a lens is arranged in front of the light source, and the lens is composed of two lenses, an inner lens and an outer lens, and the The inner lens includes a cylindrical lens cut that directly faces the row or column of the LED lamps and converts the light from the LED lamps into parallel rays in one direction, and a row of the LED lamps located at an intermediate position between the adjacent cylindrical lens cuts. Or a substantially isosceles triangle whose surface facing a row is the incident surface for light from this column or row, and the same surface is a reflective surface for light from the adjacent column or row to form parallel rays in the same direction as the cylindrical lens cut. An LED lighting device for a vehicle, characterized in that a screen-like reflective cut is provided, and the outer lens is provided with a lens cut exclusively for setting light distribution characteristics.
