Moreover, in thus configured lighting device 10, the control of the control unit 59 and the 2nd power supply unit 52 of the 1st power supply unit 51
Portion 60 processed has following function: being supplied respectively to electric power to the 1st light source 37 and the 2nd light source 38 and them is made to shine, and make by the 1st light
Illumination light changeable colour in defined color reproduction region made of the light colour mixture that the light and the 2nd light source 38 that source 37 issues issue,
Also, proceed as follows control, that is, keep the upper limit side of the light beam of color reproduction region low in the high side of colour temperature and colour temperature
Side in either one peak value with light beam, and make light beam value between the low side in the high side of colour temperature and colour temperature
Continuously.
It is indicated in Fig. 1, it is reproducible when using 2 light source 38 of the 1st light source 37 and colour temperature 2300K of colour temperature 6000K
The relationship of colour temperature and relative root mean square error (relative beam).
Assuming that when making the 1st light source 37 and the 2nd light source 38 distinguish full luminous point lamp, intermediate in reproducible reference color temperature is produced
Raw relative root mean square error reaches maximum peak value P1, and colour temperature at this time becomes 3500K or so.If from the 1st light source 37 and the 2nd light is made
Source 38 respectively the state of full luminous point lamp, dimmed for changeable colour and in a manner of for example making 38 dim light of the 2nd light source, then relatively
Light output can be declined to a great extent from peak value P1 to making the 2nd light source 38 turn off the light and the only colour temperature 6000K of 37 lighting of the 1st light source.Equally, if
It is dimmed in a manner of making 37 dim light of the 1st light source, then relative root mean square error can be declined to a great extent from peak value P1 to putting out the 1st light source 37
Lamp and the only colour temperature 2300K of 38 lighting of the 2nd light source.Therefore, if making illumination light changeable colour, light beam can be significantlyd change.
It is to proceed as follows control in present embodiment, that is, in the control unit 59 and the 2nd using the 1st power supply unit 51
In the state that the control unit 60 of power supply unit 52 makes the lighting of both the 1st light source 37 and the 2nd light source 38, make to issue using the 1st light source 37
Light and the 2nd light source 38 issue light colour mixture made of illumination light changeable colour in defined color reproduction region A.
The variable color temperature range of color reproduction region A is that control can to make the lighting of both the 1st light source 37 and the 2nd light source 38
5000K~2700K of reproduction.
The upper limit side U of color reproduction region A is control for than the tune for making the 1st light source 37 and the full luminous point lamp of the 2nd light source 38
The low degree of dimming of luminosity, and it is lower than peak value P1 when making the 1st light source 37 and the 2nd 38 full luminous point lamp of light source.Moreover, as follows
It is controlled, that is, make the upper limit side U of color reproduction region A that there is the peak value P2 of relative root mean square error in the high side of colour temperature, and
And keep relative root mean square error (light beam value) continuous from the peak value P2 of the high side of colour temperature to the low side of colour temperature.About peak value
P2, at colour temperature 5000K and 2700K, supply to the electric power of the 1st light source 37 and the 2nd light source 38 is identical watt (watt) number
When, 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, high in colour temperature
One side generates peak value P2.Moreover, the difference control of the high low side in side and colour temperature of the colour temperature of the upper limit side U of color reproduction region A
Make the range within 20%.
The lower limit side D of color reproduction region A becomes the lower limit value that can make the 1st light source 37 and 38 dim light of the 2nd light source.
Moreover, proceeding as follows control using the control unit 59 of the 1st power supply unit 51 and the control unit 60 of the 2nd power supply unit 52
System, that is, in the state of making the lighting of both the 1st light source 37 and the 2nd light source 38, make the light and the 2nd light issued using the 1st light source 37
Illumination light changeable colour in the A of color reproduction region made of the light colour mixture that source 38 issues, therefore, even if changeable colour, light relatively is defeated
It will not significantly change, can change colour in the case where maintaining constant brightness out.
That is, but passing through the upper limit in color reproduction region A in fact, can get the light output higher than color reproduction region A
Side U limits light output, even if changeable colour, relative root mean square error will not be significantlyd change, and can be become in the case where maintaining constant brightness
Color.
Moreover, being carried out in such a way that the high side of the colour temperature in color reproduction region A has the peak value P2 of relative root mean square error
Control, therefore, in color reproduction region, the high side of the colour temperature of the A side low with colour temperature can be fed to the 1st light source 37 and the 2nd
The Electric control of light source 38 is identical wattage, so, it is easy to carry out brightness adjustment control.
Moreover, because the difference control of the low side in the colour temperature of the upper limit side U of color reproduction region A high side and colour temperature is existed
Range within 20%, so, even if changeable colour, it is also difficult to feel the variation of brightness.If the upper limit side of color reproduction region A
The difference of the high side of the colour temperature of U and the low side of colour temperature is greater than 20%, if then changeable colour, is easy to feel the variation of brightness.
In addition, as shown in figure 5, the control unit 59 of the 1st power supply unit 51 and the control unit 60 of the 2nd power supply unit 52 can also be used,
It is to be present in the low side of colour temperature by the peak value control of the relative root mean square error of color reproduction region A.
Moreover, as shown in fig. 6, the control unit 59 of the 1st power supply unit 51 and the control unit 60 of the 2nd power supply unit 52 can also be used,
It is to be present in two described in the side low with colour temperature of the high side of colour temperature by the peak value control of the relative root mean square error of color reproduction region A
Place.At this point, the upper limit side U of color reproduction region A becomes flat (plat), even if changeable colour, relative root mean square error is also unchanged, can
Change colour in the case where maintaining constant brightness.Such control can be by making in the high side of the colour temperature of color reproduction region A and color
The low side of temperature supplies different to the electric power of the 1st light source 37 and the 2nd light source 38 and realizes.
More than, having used embodiment, the present invention is described, but technical scope of the invention be not limited to it is described
Range described in embodiment.It is to be appreciated that those skilled in the art that numerous variations or improvement can be implemented to the embodiment.
Moreover, according to the record of claim it can be appreciated that these also belong to technical scope of the invention by the form for changing or improveing.
