Abstract (en)
Lighting device that can diversely adjust brightness and color of the light in accordance with a user's taste. The lighting device includes an external power supply, a rectifying section (10), a stabilizing section (20), and an adjustment section for lighting at least two lamps having different color temperature in the range of about 1600-2700 DEG K and 5000-10000 DEG K respectively, so that color and brightness of the emitted light are adjusted by manipulation of the adjustment section. The two lamps are tubes having multiwaves by mixing three or more fluorescent powders to change the brightness and the color. The tubes represent a tube section (30). The lighting device further includes a manipulation section (40) composed of a display for displaying an adjustment state of the brightness and the color of the light within a predetermined range, and an adjustment switch for adjusting the brightness and the color within the predetermined range. <IMAGE>
