Suppose that in the middle of reproducible reference color temperature, produce relative root mean square error reach maximum peak value P1, colour temperature now becomes about 3500K when making the 1st light source 37 and the full luminous point lamp of the 2nd light source 38 difference.If from make the 1st light source 37 and the 2nd light source 38 respectively full luminous point lamp state, in order to changeable colour such as to make the mode of the 2nd light source 38 dim light carry out light modulation, then relative root mean square error can decline to a great extent to making the 2nd light source 38 turn off the light and the colour temperature 6000K of only the 1st light source 37 lighting from peak value P1.Equally, if to make the mode of the 1st light source 37 dim light carry out light modulation, then relative root mean square error can decline to a great extent to making the 1st light source 37 turn off the light and the colour temperature 2300K of only the 2nd light source 38 lighting from peak value P1.Therefore, if make illumination light changeable colour, then light beam can significantly change.
In present embodiment, control as follows, namely, under the state utilizing the control part 60 of the control part 59 of the 1st power supply unit 51 and the 2nd power supply unit 52 to make the lighting of both the 1st light source 37 and the 2nd light source 38, illumination light changeable colour in the color reproduction region A specified of the light colour mixture that the light making to utilize the 1st light source 37 to send and the 2nd light source 38 send.
The variable color temperature scope of color reproduction region A controls as making the lighting of both the 1st light source 37 and the 2nd light source 38 and reproducible 5000K ~ 2700K.
The upper limit side U of color reproduction region A controls as than making the degree of dimming that the degree of dimming of all full luminous point lamp of the 1st light source 37 and the 2nd light source 38 is low, and lower than peak value P1 when making the 1st light source 37 and the full luminous point lamp of the 2nd light source 38.And, control as follows, that is, make the upper limit side U of color reproduction region A have the peak value P2 of relative root mean square error in the side that colour temperature is high, further, relative root mean square error (light beam value) is made to be continuous print from the peak value P2 of the high side of colour temperature to the side that colour temperature is low.About peak value P2, when under colour temperature 5000K and 2700K, when the electric power being supplied to the 1st light source 37 and the 2nd light source 38 is identical watt (watt) number, the luminous efficiency of the 1st light source 37 of color of sunshine is higher than the luminous efficiency of the 2nd light source 38 of light bulb color, therefore, peak value P2 is produced the side that colour temperature is high.And the difference of the side that the colour temperature of the upper limit side U of color reproduction region A is high and the low side of colour temperature controls the scope within 20%.
The lower limit side D of color reproduction region A becomes the lower limit that can make the 1st light source 37 and the 2nd light source 38 dim light.
And, the control part 60 of the control part 59 of the 1st power supply unit 51 and the 2nd power supply unit 52 is utilized to control as follows, namely, under the state making the lighting of both the 1st light source 37 and the 2nd light source 38, illumination light changeable colour in the A of color reproduction region of the light colour mixture that the light making to utilize the 1st light source 37 to send and the 2nd light source 38 send, therefore, even if changeable colour, relative root mean square error also can not significantly change, can the variable color when maintaining constant brightness.
That is, in fact, can obtain the light output higher than color reproduction region A, but limit light output by the upper limit side U at color reproduction region A, even if changeable colour, relative root mean square error also can not significantly change, can the variable color when maintaining constant brightness.
And, the mode with the side high in the colour temperature of color reproduction region A with the peak value P2 of relative root mean square error controls, therefore, the Electric control being supplied to the 1st light source 37 and the 2nd light source 38 can be identical wattage by the side low with colour temperature in the side that the colour temperature of color reproduction region A is high, so, easily carry out brightness adjustment control.
And the difference of the side that the colour temperature because of the upper limit side U by color reproduction region A is high and the low side of colour temperature controls the scope within 20%, so, even if changeable colour, be also difficult to feel the change of brightness.If the difference of the side that the colour temperature of the upper limit side U of color reproduction region A is high and the low side of colour temperature is greater than 20%, if then changeable colour, then easily feel the change of brightness.
In addition, as shown in Figure 5, also can utilize the control part 59 of the 1st power supply unit 51 and the control part 60 of the 2nd power supply unit 52, the peak value of the relative root mean square error of color reproduction region A is controlled as being present in the low side of colour temperature.
And, as shown in Figure 6, also can utilizing the control part 59 of the 1st power supply unit 51 and the control part 60 of the 2nd power supply unit 52, the peak value of the relative root mean square error of color reproduction region A being controlled for being present in two places described in the high side of colour temperature and the low side of colour temperature.Now, the upper limit side U of color reproduction region A becomes smooth (plat), even if changeable colour, relative root mean square error is also unchanged, can the variable color when maintaining constant brightness.It is different and realize that this kind controls electric power by making to be supplied to the 1st light source 37 and the 2nd light source 38 in the side that the side that the colour temperature of color reproduction region A is high is low from colour temperature.
Above, used embodiment to describe the present invention, but technical scope of the present invention is not limited to the scope described in described embodiment.It is to be appreciated that those skilled in the art that and can implement numerous variations or improvement to described embodiment.And the record according to claim can be understood, these also belong to technical scope of the present invention through the form changed or improve.
