10. A method of controlling an optical system with optical fiber performed by a control unit, the method comprising:
(a) collecting information;
(b) generating a control signal based on the information collected in (a); and
(c) controlling a light source unit according to the control signal generated in (b);
wherein the light source unit includes a first light source incorporated into a bezel of a lamp and positioned outside a light radiating area of the lamp, the first light source being disposed at a first end of the optical fiber, the optical fiber extending through the light radiating area of the lamp;
wherein generating the control signal further includes generating, by the control unit, a first light emitting signal so that the light radiating area radiates light of the first light source, and the method further comprises applying, by the control unit, a voltage to the first light source;
wherein generating the control signal further includes generating, by the control unit, a second light emitting signal so that the light radiating area radiates light of a second light source disposed at a second end of the optical fiber, and the method further comprises applying, by the control unit, a voltage to the second light source; and
wherein generating the control signal includes generating, by the control unit, a third light emitting signal so that the light radiating area radiates light having an intermediate wavelength of the first light source and the second light source, and
controlling the light source unit includes
determining, by the control unit, a mixing ratio of the first light source and the second light source, and
alternately applying, by the control unit, a voltage to the first light source and the second light source so that each of the first light source and the second light source has a light generation time proportional to the mixing ratio.
