Cup holder for vehicle

A cup holder for a vehicle, the cup holder comprising:

• a holder body for storing a cup and having a thermoelectric element to cool or heat the cup stored therein;
• a supporting part having a front end protruded to an inner side surface of the holder body and a rear end supported by an elastic part to thereby support a side surface of the cup when the cup is stored and having a light source capable of expressing a plurality of colors to thereby irradiate light toward the cup;
• a temperature sensor provided on the holder body to thereby measure a temperature thereof;
• and
• a controlling part changing a color of the light source of the supporting part in response to the measured temperature,
• wherein an outer surface of the holder body is provided with a contact sensor sensing whether the cup is stored in the holder body, and the contact sensor is in contact or lose contact with a lower end of the supporting part rotated around the elastic part by the cup which is stored in the holder body or away from the holder body, and
• wherein the controlling part operates the thermoelectric element only when the cup is determined by the controlling part to be stored in the holder body through the contact sensor, wherein the supporting part is provided with two light sources capable of expressing blue and red colors, and the controlling part independently adjusts an intensity of each light source, wherein the controlling part controls the supporting part to gradually irradiate light in the blue color as the temperature of the holder body becomes low and controls the supporting part to gradually irradiate light in the red color as the temperature of the holder body becomes high.
