Vehicle indicator lamp

A vehicle lamp, comprising:

• a reflector for diffusing and reflecting light from a light source bulb, the light source bulb having a reference axis, wherein the reflector includes a reflective surface divided into a plurality of reflective regions divided concentrically with the reference axis as the center, and an inner peripheral edge region that reflects light in a direction substantially parallel to the reference axis and includes an outer peripheral edge region that reflects light in a direction close to the reference axisi
• a transparent lens connected to the reflector;
• and
• a condenser lens connected to the transparent lens in front of the light source bulb.

A method for designing a vehicle lamp to substantially eliminate the loss of reflected light, the vehicle lamp including a light source bulb, a reflector and a transparent lens, comprising:

• dividing a reflective surface having a smooth surface without steps and ridges of the reflector into a plurality of concentric reflective regions centered about the reference axis;
• determining the shape of an inner peripheral edge region of the reflector to reflect light in a direction substantially parallel to a reference axis of the light source bulb;
• and
• determining the shape of an outer peripheral edge of the reflector to reflect light in a direction close to the reference axis by dividing a first target light distribution pattern into a plurality of pattern regions and calculating the shape of the reflector to produce the light beam required to realize the distribution pattern for each pattern region;
• and
• utilizing a condenser lens to focus direct light from the light source bulb.
