Abstract:
The present invention relates to a vehicular LED lamp for freezing prevention using transparent conductive oxide (ITO). The vehicular LED lamp includes: a housing made of a heat dissipation material, and opened at a front side thereof, the housing including an outer shell formed to protect internal constituent elements; a headlamp LED PCB unit including one or more LEDs configured to drive a headlamp to identify the position of a vehicle; and an ITO conductive heating member deposited on the inner surface of a head lens of the LED lamp, which is coupled to the housing, the head lens being formed by depositing a diffusion preventing layer on a substrate thereof, and depositing an ITO thin film on the diffusion preventing layer, followed by thermal treatment and crystallization, thereby improving the light-outputting efficiency of an LED chip and reducing the energy consumption of the LED lamp.
