<p>PURPOSE: An LED module driving circuit is provided to reduce the heat generation by reducing the load on the variable resistances at each LED line. CONSTITUTION: A voltage regulator (120) receives power from the input power. The voltage regulator controls the voltage. An LED array (130) operates using the supplied voltage. The LED array includes multiple LED lines. Multiple voltage measurement units (140) measure the output voltage of the LED lines. [Reference numerals] (120) Voltage regulator; (140a,140b,140n) Voltage measurement unit; (150a,150b,150n) Adjustable resistance; (160a,160b,160n) Current path unit; (170) Control unit</p> |
