[0031] The method of adjusting the white light is similar to that of adjusting the R-LED unit, the G-LED unit and the B-LED unit. The user can adjusts the knob W1 which may be a variable resistor. When the knob W1 is adjusted, the resistance of the resistor varies and the second input signal Sig2 inputted to the second PWM unit 24 is adjusted accordingly. Then, the second PWM unit 24, in response to the second input signal Sig2, adjusts the pulse width of the second light-adjusting signal SM2. For example, each of the pulse widths of the first cycle WT1, the second cycle WT2 and the third cycle is adjusted to 50% of each cycle thereof.

TABLE-US-00001 TABLE 1 hue grey Red hue Green hue Blue hue scale 000~111 000~111 000~111 mix 000~111 111 + 111 111 + 111 000 + 000 111111111111000000 000~111 111 + 111 000 + 000 111 + 111 111111000000111111
[0038] In Table 1, each of the red hue, the green hue and the blue hue is represented by three binary bits; i.e., the red hue is represented by a value selected from eight different hue values (000-111), and each of the green hue and the blue hue is also represented by a value selected from eight different hue values (000-111). The grey scale represents brightness, and is also represented by three binary bits, and each color has a brightness selected from eight different brightnesses of grey scale. When the user selects the desired color of the palette 451, the application program of the mobile device 45 can generate a corresponding composite value including a corresponding RGB hue value and a corresponding grey scale value. For examples, in Table 1, the hue value of the red color is 111, the grey scale value of the red color is 111, and it means the red color is the most vivid red and the brightest red color. The hue value of the green color is 111, the grey scale value of the green color is 111, and it means the green color is the most vivid green and the brightest green color. The hue value of the blue color is 000, the grey scale value of the blue color is 000, and it means the blue color is the palest blue and the darkest blue color. All the above values can be concatenated together to get the mixed value of eighteen binary bits 111111111111000000. In this preferred embodiment, the red color and the green color can be mixed together to obtain a bright yellow color, but the hue value of blue color is low and the brightness of the blue color is darkest, and therefore the mixed color light of the red light and the green light will be a yellow color light after mixing the three primary color lights. When the user selects the bright yellow color by his/her intuition, the application program of the mobile device 45 can generate the corresponding composite value of the hue and the grey scale of the yellow color in real time, which is 111111111111000000.
[0039] Similarly, in Table 1, another preferred embodiment shows that the hue value of the red color is 111, the grey scale value of the red color is 111, and it means the red color is the most vivid red and the brightest red color. The hue value of the green color is 000, the grey scale value of the green color is 000, and it means the green color is the palest green and the darkest green color. The hue value of the blue color is 111, the grey scale value of the blue color is 111, and it means the blue color is the most vivid blue and the brightest blue color. All the above values can be concatenated together to get the mixed value of eighteen binary bits 111111000000111111. In this preferred embodiment, the red color and the blue color can be mixed together to obtain a bright purple color, but the hue value of green color is low and the brightness of the green color is darkest, and therefore the mixed color light of the red light and the blue light will be a purple color light after mixing the three primary color lights. When the user selects the bright purple color by his/her intuition, the application program of the mobile device 45 can generate the corresponding composite value of the hue and the grey scale of the purple color in real time, which is 111111000000111111.
[0040] In other preferred embodiment, the mobile device 45 can has a built-in color code table as shown in Table 2. When the user selects the desired color he/she wants the illumination device 30 to emit, the color code will be transmitted to the control unit 40 by the wireless signal SW1 in real time.
TABLE-US-00002 TABLE 2 hue grey Color code scale 0000~FFFF mix 00~FF FF + 2E3A FF2E3A
[0041] Taking for an example, in Table 2, the hue is represented by the color code having four hexadecimal digits, and the grey scale is presented by two hexadecimal digits. In this preferred embodiment, the number of digits can be adjusted flexibly, depending on the requirement. When the user clicks to choose the hue and the brightness of the desired color in the palette 451, the corresponding color code 2E3A and the brightness value FF will be transmitted to the control unit 40 through the wireless signal SW1 including the corresponding color code 2E3A and the brightness value FF. The control unit 40 may further include an interpreting unit 47, which can convert the color code 2E3A to mixed proportion ratios of the red, the green and the blue colors. For examples, when the purple color having cooler blue component is chosen, the interpreter unit 47 converts the color code to mixed proportion ratios 30%, 10% and 60% of the RGB colors respectively. When the purple color having warmer red component is chosen, the interpreting unit 47 converts another color code to another mixed proportion ratios 60%, 10% and 30% of the RGB colors respectively. Meanwhile, the interpreting unit 47 transmits the grey scale value and the mixed proportion ratios of the RGB colors to the first PWM unit 43 and the second PWM unit 44, which can adjust the color of the mixed light emitting from the R-LED unit 361, the G-LED unit 362 and the B-LED unit 363, and the brightness of the second lamp 302 by using the method of adjusting pulse widths outputting from the first and the second PWM units 43 and 44.
[0042] Accordingly, please refer to Table 1 and
[0043] The information of hue and grey scale of each color in the aforementioned preferred embodiment can be interpreted to a single bit value or a plurality of bit values transmitted by the wireless signal SW1. For instance, the hue of each RGB color can be presented by 8 bits, and thus 24 bits presents a composite hue of RGB colors. The grey scale of the brightness of the mixed primary color light can be represented by using 8 bits, rather than by using 8 bits for each color light. Thus, it can reduce loading and data transmission for processing. On the contrary, when more bit numbers are used to represent the hue and grey scale, the more detailed or exact light is emitted from the illumination device 30.

Accordingly, the skilled person in the art can implement the present invention, which is rich in the industrial utilization.
