A vehicle light can include a light emitting diode (LED) serving as a light source and an optical system for controlling a light distribution pattern of the light beams from the LED light source utilizing a light guide (such as a lens body having an inner reflecting surface). The vehicle light can project illumination light with a low beam light distribution pattern. The vehicle light can include an LED light source and a lens body serving as a light guide. The lens body can include a light incident surface, a reflecting surface, and a light exiting surface. The LED light source can have a rearmost end light emitting point from which light beams are emitted to form a bright-dark boundary line. Among the light beams, perpendicularly incident light beams not subjected to refraction can be projected toward the bright-dark boundary line while obliquely incident light beams that are subjected to refraction can be corrected to be directed in a lower angular direction than the bright-dark boundary line and to be mixed with the other light beams, thereby preventing color shading of illumination light from the vehicle light.

The plurality of antennas (4) are arranged so as to constitute a pattern. Each of the antennas (4) has three segment-shaped first element parts (4a) and three segment-shaped second element parts (4b). The three first element parts (4a) radially extend from the center of the antenna (4) by substantially the same length such that any two of the three first element parts (4a) form an angle of 120° with each other. Each of the second element parts (4b) are connected to an outer edge of a corresponding one of the first element parts (4a).

Data for a 3D sheet metal part model is stored in a file. The stored data includes features of the part and manufacturing information. When different manufacturing processes are used, different geometry can be created. The file can store multiple processes for manufacturing the part and the geometry associated with each process. Thus, when manufacturing the part, the user can view information for multiple stored processes because all of the information is stored together. In addition, both 2D and 3D data is stored for the part.
