Description of the Invention (1) Field of the Invention The present invention relates to a lighting device that can adjust the brightness and hue of a lamp according to user preferences and usage situations. BACKGROUND OF THE INVENTION Most of the existing lighting lamps are monochromatic lighting lamps with a certain brightness. Recently, users are increasingly demanding a comfortable lighting environment. In order to make the brightness of the lighting lamps approach natural light, many lighting lamps use three-wavelength lamps. However, such a three-wavelength illuminating lamp cannot adjust the brightness of the lamp according to the place of use, or adjust the three primary colors of R, G, and B to the optimal state according to personal preference. SUMMARY OF THE INVENTION The disadvantages of the conventional lighting device described above are that it is impossible to adjust the brightness of the light depending on the place of use, or to adjust the three primary colors of R, G, and B to the optimal state according to personal preference. Moreover, the feeling of hue varies depending on personal preferences. For example, the brightness of a lamp can be adjusted manually or automatically, so that the color temperature is maintained at 4000 ° K in the morning, the color temperature is maintained at 60,000 ° K during the day, and the color temperature is maintained at night. Maintaining the Optimal State of 3 0 0 ° K "But conventional lighting does not have this function. The invention is a lighting device capable of solving the above problems. The invention provides a lighting device which can freely adjust the brightness and hue of the lighting lamp according to the use state, purpose, environment and user preference of the lamp. The invention consists of a power rectifier, a lighting lamp, a ballast and a controller group.

Description of the Invention (4) " When it becomes R, G, B, Τ and other single-end waveform color lamps, if you want to make the human eye see the mixed color bright light, you need thousands of kilometers away. Watch from a distance. However, under such a distance, its light intensity has become quite weak and cannot be used as a general lighting. Therefore, the previous technology generally only used it for decoration or eye-catching purposes. In other words, the 忒 lighting fixture cannot be used as ceiling lighting only 1-2 meters away from a person's head or eyes. As mentioned above, many existing people only have a conceptual concept, such as how to mix bright lights easily in monochromatic lamps such as LG, B, and what kind of control methods and types are necessary to easily mix bright lights. The idea of a qualifier such as a fixture, but this technology was developed with a completely new concept. In the technology of the present invention, most fluorescent powers (such as R, G, and B) are mixed, and in the lamp tube 13, two different Kevin temperature lamps are produced and used. That is, one is to use extremely low Kelvin temperature (arbitrarily set within _ 2, 700 ° K), and the other is to use extremely high Kelvin temperature (about 5,000-10, 000 ° K). Because the foregoing lamps are mixed with fluorescent particles of a private unit to generate light, and the color rendering index of the light source is above 75, human eyes have no rejection to the lamps themselves. In addition, basically, because R, G, B and other pigments have reached a perfect state of coordination, as long as the output of high and low Kelvin temperature is adjusted, the overall Kelvin temperature can be easily adjusted.
