<p>PURPOSE: A light device is provided to include a circuit which protects the circuit element from a short circuit and overvoltage and a micro-current limit circuit which limits the illumination of luminous elements even when a micro-current flows and to have a small amount of inter-elements while not including a capacitor and an inductor, thereby reducing power consumption and improving power factors. CONSTITUTION: A light device includes: a base unit(820); a light emitting unit(822) with luminous elements arranged on the one surface of the base unit or the inner side thereof; and a driving circuit unit(824) formed at the outer side of the base unit. The driving circuit provides constant current to the luminous elements by using a constant current diode, and does not include an inductor and a capacitor.</p> |
