HEAD LAMP FOR VEHICLE

摘要

PURPOSE: A head lamp for a vehicle is provided to improving heat radiation efficiency by securing a wind entry region by partly eliminating the side of cooling fan housing and offering sufficient air volume to a heat radiating part. CONSTITUTION: A front window(110) covers an opening part of the front side of housing(100). An LED part(130) comprises a plurality of LEDs arranged on the top of a substrate at regular intervals. A heat radiating part(140) is installed in order to discharge heat created in the LED part to outside. A cooling fan(150) is located between a dust cover(120) and the heat radiating part. The cooling fan secures a wind entry region and is separately arranged from the dust cover in order to increase air volume. A driving part(160) controls a driving state of the cooling fan and LED part in the lower side of the housing. A thermistor(170) senses temperatures of the LED part by measuring a current in the rear side of the LED part.
