<p>PURPOSE: A color temperature controller of a tunnel lamp is provided to minimize power consumption while securing the view of a driver by maintaining the color temperature inside and outside the tunnel same. CONSTITUTION: A color temperature controller of a tunnel lamp is comprised of an input unit(100) and a processing unit(200). The input unit includes a position detecting unit(110), a color temperature sensing unit(120), and an input microprocessor(160). The color temperature sensing unit senses the temperature of external tunnel and generates a color temperature signal. The color temperature signal is transmitted to the input microprocessor. The color temperature sensing unit measure ambient temperature. A temperature sensing unit transmits a temperature signal the input microprocessor. The input microprocessor analyzes a position signal, a temperature signal, and a temperature signal. The input microprocessor controls the temperature control device(10).</p> |
