Distribution controls portion 140 controls the luminous intensity distribution of light-emitting component 133.With reference to accompanying drawing, distribution controls portion 140 is further described.

Fig. 4 (a) is the sectional view of the cutting plane A-A schematically shown in Fig. 3 (a).Fig. 4 (b) is the sectional view of the cutting plane B-B schematically shown in Fig. 3 (a).Fig. 5 (a) is the sectional view of the cutting plane C-C schematically shown in Fig. 3 (a).Fig. 5 (b) is the sectional view of the cutting plane D-D schematically shown in Fig. 3 (a).

As shown in Fig. 4 (a), appliance body 120 is fixed in distribution controls portion 140, and covering luminous element 133, segmentation multiple substrates 131 between electrical connection section and power suppling part.The material in distribution controls portion 140 such as comprises resin.Distribution controls portion 140 covers whole light source portion (charging part) 130.Therefore, distribution controls portion 140 has the function of protection light source portion 130.In addition, the protuberance 145 corresponding with the electrical connection section of substrate 131 and power suppling part is formed with in the inner circumferential side in distribution controls portion 140.It is longer than the size of connector that protuberance 145 is formed as the size on ring-type direction and circumference.Namely, because distribution controls portion 140 is by rotating the structure that can be loaded and unloaded on appliance body 120, thus in order to when preventing from rotating distribution controls portion 140 and electrical connection section CN and electric wire 135 disturb, distribution controls portion 140 has the size in the circumferential protuberance 145 longer than connector size.

Distribution controls portion 140 has lens section 141.Lens section 141 has: part 1 141a, part 2 141b, the 3rd part 141c.And, between part 1 141a and the 3rd part 141c, between part 2 141b and the 3rd part 141c, the inner circumferential side of part 1 141a, the outer circumferential side of part 2 141b the region of the par 141e corresponding with substrate 131, be formed with light diffusion part 141f.Such as form light diffusion part 141f by implementing Texture.Also light diffusion part 141f can be formed by pasting the additive methods such as diffusion sheet.Part 1 141a covers the light-emitting component 133 (being light-emitting component 133L and light-emitting component 133D in the example of Fig. 4 (b)) of inner circumferential side row, and controls the luminous intensity distribution of the light-emitting component 133 of inner circumferential side row.3rd part 141c covers the light-emitting component 133 (being light-emitting component 133R, light-emitting component 133G and light-emitting component 133B in the example of Fig. 4 (b)) of middle column, and controls the luminous intensity distribution of the light-emitting component 133 of middle column.Part 2 141b covers the light-emitting component 133 (being light-emitting component 133L and light-emitting component 133D in the example of Fig. 4 (b)) of outer circumferential side row, and controls the luminous intensity distribution of the light-emitting component 133 of outer circumferential side row.That is, the distribution controls portion 140 of embodiment is according to often arranging the independent luminous intensity distribution controlling the light-emitting component 133 be disposed on each row.

Thus, alleviate the form and aspect inequality on cover 150 lower surface (light-emitting area) 150a and brightness disproportionation, the homogenising of colourity and brightness can be realized.

At this, if the light-emitting component 133 of the light-emitting component 133 not making outer circumferential side arrange and inner circumferential side row is lighted, and only make the light-emitting component 133 of middle column light, then according to the shape of lens 141, sometimes on the lower surface 150a of cover 150, produce bright line.More specifically, such as, as the arrow A 11 shown in Fig. 4 (b) and arrow A 12, if light transmission the 3rd part 141c radiated from the light-emitting component 133 of middle column incides at least any one part part 1 141a and part 2 141b, then bright line can be produced on the lower surface 150a of cover 150.

To this, on the surface of the 3rd part of the lens section 141 of embodiment, DIFFUSION TREATMENT portion 141d is set.Such as, the body at random of point-like and so-called gauffer apperance is formed on the surface of the 3rd part 141c of lens section 141.And, incide a part of light the light of lens section 141 from light-emitting component 133, and in outgoing plane reflection the light of par towards the rear side of lens section 141, then towards the region of the par 141e in distribution controls portion 140.Suppose not to be formed with light diffusion part 141f, light can reflect at the par 141e in distribution controls portion 140, and the light after reflection can penetrate from lens section 141.Thus, produce bright line, and this bright line can mirror cover 150 thus produce brightness disproportionation on cover 150.To this, by forming light diffusion part 141f on the par 141e in distribution controls portion 140, make to be spread towards the light of par 141e by light diffusion part 141f.Therefore, lens section 141 can not produce the strong bright line of luminous intensity, can suppress cover 150 produces brightness disproportionation.

Thus, as the arrow A 13 shown in Fig. 4 (b) and arrow A 14, the light through the 3rd part 141c is diffused by the DIFFUSION TREATMENT portion 141d on the surface of the 3rd part 141c.Then, the amount inciding the light of part 1 141a and part 2 141b can reduce.Therefore, it is possible to suppress to produce bright line at the lower surface 150a of cover 150.On the other hand, on the surface of part 1 141a and the surface of part 2 141b, DIFFUSION TREATMENT portion is not set.Therefore, it is possible to suppress the decline of the luminous flux of ligthing paraphernalia 100.In addition, when in order to realize slimming object the distance between cover 150 and lens section 141 is set to less, even if be formed with light diffusion part 141f, sometimes also cannot suppress the generation of bright line.Now, also DIFFUSION TREATMENT can be implemented at the plane of incidence of lens section 141.

As the explanation in Fig. 2, substrate 131 is fixed on the lower surface 120a of appliance body 120.As shown in Fig. 5 (a), substrate 131 has hole 131b.On the other hand, (light-emitting area side) outstanding jut 123 is provided with downwards at the lower surface 120a of appliance body 120.When substrate 131 being installed on the lower surface 120a of appliance body 120, first, by the jut 123 that the hole 131b of substrate 131 aims at appliance body 120, the jut 123 of appliance body 120 is inserted in the hole 131b of substrate 131.Thereby, it is possible to by temporary fixed for substrate 131 or be positioned over the lower surface 120a of appliance body 120 temporarily.

As mentioned above, appliance body 120 is fixed in distribution controls portion 140.As shown in Fig. 5 (b), distribution controls portion 140 has claw 143.Claw 143 has hook-like shape.The leading section of claw 143 extends along the direction almost parallel with the lower surface 120a of appliance body 120.On the other hand, appliance body 120 has hole 125.The length D1 in hole 125 is longer than the length D2 of the leading section of claw 143.When distribution controls portion 140 is installed on appliance body 120, first, claw 143 is aimed at the hole 125 of appliance body 120, and by the hole 125 of claw 143 insertion device main body 120.Then, distribution controls portion 140 is rotated in the direction to the arrow A 16 in Fig. 4 (a).Thus, appliance body 120 is fixed in distribution controls portion 140.More specifically, each claw 143 is blocked with the rear side of appliance body 120, thus moves distribution controls portion 140 to appliance body 120.Thus, with the state of chucking substrate 131 between appliance body 120 and distribution controls portion 140, appliance body 120 and distribution controls portion 140 are fitted together to.

Light source portion 130 and indirect light light source portion 160 is controlled thereby, it is possible to independent.And, brightness adjustment control (controlling separately) can be carried out for each glow color.Therefore, with regard to light source portion 130, by adjusting the light modulation ratio of each glow color and changing the luminous power of each glow color, make the glow color colour mixture of incandescent light color (L), color of sunshine (D), red (R), green (G), blue (B), thus desired glow color (independent control model) can be showed.Such as, user, by least any one button in " R " button 185 of remote controller 180, " G " button 186, " B " button 187, can adjust the light modulation ratio of each glow color thus change the luminous power of each glow color.In the remote controller 180 shown in Fig. 8 (a) and Fig. 8 (b), " R " button 185, " G " button 186, " B " button 187 are hidden in cover portion 180a usually, outside " R " button 185, " G " button 186, " B " button 187 are presented at by sliding closure portion 180a by user on the other hand.

In the ligthing paraphernalia 100 involved by embodiment, in order to present the light space conformed to living scene, can desired pattern be selected to switch from multiple lighting pattern.More specifically, in light-emitting component 133 and light-emitting component 163, the multiple mode setting information (lighting pattern information) that have adjusted the luminous power of each glow color are stored in pattern storage portion 118a.User selects by remote controller 180 the lighting pattern being stored in pattern storage portion 118a, thus can reproduce lighting pattern.

Such as, " beautiful " pattern, " comfortable " pattern, " arenas " pattern, " help of sleeping " pattern (the 1st lighting pattern) is set with.

In " beautiful " pattern, the glow color colour mixture of incandescent light color (L), color of sunshine (D), red (R), green (G), blue (B) is showed the high and light of the daylight colour system that color rendition is superior of color rendering properties, thus make dining table or color become bright-coloured.It is such as " 95 " that the average color of the mixed light in " beautiful " pattern reproduces evaluation number (Ra).Such as, user, by " beautiful " button 181 of pressing remote controller 180, can select and perform " beautiful " pattern.

In " comfortable " pattern, combined by the light upward of the light down of the incandescent light color (L) by light source portion 130 and the incandescent light color (L) of indirect light light source portion 160, with the whole space of soft optical illumination of incandescent light color (L), present easy comfortable space.Such as, user, by " comfortable " button 182 of pressing remote controller 180, can select and perform " comfortable " pattern.

In " arenas " pattern, the light upward of the incandescent light color (L) of indirect light light source portion 160 is only used to throw light on.Can ceiling face be irradiated in " arenas " pattern, present the sensation that class origin faces cinema, create the light space can enjoying home theater.Such as, user, by " arenas " button 183 of pressing remote controller 180, can select and perform " arenas " pattern.

In " help of sleeping " pattern, do not make the light-emitting component 133B of the light-emitting component 133D of radiation color of sunshine (D) light and blue (B) light of radiation light, make the glow color colour mixture of incandescent light color (L), red (R), green (G).In " help of sleeping " pattern, the light that epiphysin degree of suppression is lower can be realized, reduce the bad influence of night illumination to sleep, impel user to sleep soundly.Average color reproduction evaluation number (Ra) of the mixed light in " help of sleeping " pattern is higher, and its each average color higher than incandescent light color (L) light, redness (R) light, green (G) light reproduces evaluates number (Ra).In " help of sleeping " pattern, the correlated colour temperature of the light (mixed light) of the glow color colour mixture of incandescent light color (L), red (R), green (G) is lower than the correlated colour temperature of incandescent light color (L) light.Such as, user, by " help of sleeping " button 184 of pressing remote controller 180, can select and perform " help of sleeping " pattern.

When reproducing the lighting pattern of so setting, user selects specific pattern by remote controller 180.If remote controller signal acceptance division 127 receives mode select signal, then the signal received is sent to set information input and output portion 115a.Set information input and output portion 115a reads by the mode setting information (lighting pattern information) selected from pattern storage portion 118, and sends to brightness adjustment control mechanism 115b.

Pwm control circuit 117a in brightness adjustment control mechanism 115b generates pwm control signal according to mode setting information and sends to ON-OFF control circuit 117b.ON-OFF control circuit 117b is according to pwm control signal control PWM, and the direct current supplied from power supply unit 110 to each light-emitting component 133 of light source portion 130 and the light-emitting component 163 of indirect light light source portion 160 exports.Thus, to correspond to the light modulation of mode setting information than the light-emitting component 133,163 controlling each glow color respectively, thus carry out luminescence with predetermined mixed light ratio, show as the glow color of colour mixture on the whole.

With reference to accompanying drawing, " help of sleeping " pattern is further described.

Transverse axis in chart shown in Fig. 9 represents wavelength (nanometer: nm).The longitudinal axis in chart shown in Fig. 9 represents relative energy.The relative spectral power distribution represented in Fig. 9 represents the light-emitting component 133G of the light-emitting component 133R of the light-emitting component 133L of radiation incandescent light color (L) light, red (R) light of radiation, green (G) light of radiation with the example of the ratio mixed light of " 0.83:0.12:0.05 ".

The spatial distribution of the mixed light radiated in " help of sleeping " pattern is at more than 600nm and have the peak value of energy in the wave-length coverage of below 650nm.In relative spectral power distribution shown in Fig. 9, when wavelength is 635nm, there is the peak value of energy.

If the maximum of the energy of spatial distribution be set to " 1 ", then the peak value of the energy of the mixed light radiated in " help of sleeping " pattern at more than 380nm and in the wave-length coverage of below 500nm is less than 0.25.In the relative spectral power distribution shown in Fig. 9, the relative energy of the peak value at more than 380nm and in the wave-length coverage of below 500nm is " 0.2 ".If the maximum of the energy of spatial distribution be set to " 1 ", then the peak value of the energy of the mixed light radiated in " help of sleeping " pattern at more than 530nm and in the wave-length coverage of below 600nm is more than 0.25 and less than 0.6.In the spatial distribution shown in Fig. 9, the relative energy of the peak value at more than 530nm and in the wave-length coverage of below 600nm is " 0.48 ".

It is " 84 " that the average color of incandescent light color (L) light that light-emitting component 133L radiates reproduces evaluation number (Ra).It is " 93 " that the average color of the mixed light of aforementioned proportion (0.83:0.12:0.05) reproduces evaluation number (Ra).Namely, compared with the situation of the light of the incandescent light color of radiation (L), by radiating light-emitting component 133L, the light-emitting component 133R of red (R) light of radiation of incandescent light color (L) light, the mixed light of the light-emitting component 133G of green (G) light of radiation, average color reproduction is evaluated number (Ra) and is improved.

Present inventor is studied the relation between the mixed light ratio of light-emitting component 133L, the light-emitting component 133R of red (R) light of radiation of radiation incandescent light color (L) light, the light-emitting component 133G of green (G) light of radiation (light modulation than) and epiphysin degree of suppression.The epiphysin effect sensitivity curve of Brainard is set to Brainard (λ), and goes out epiphysin degree of suppression according to formulae discovery below.

Brainard (λ) × relative spectral power distribution/V (λ) × relative spectral power distribution ... formula 1

The standard luminosity function that " V (λ) " in formula 1 is photopic vision.Further, epiphysin degree of suppression when only lighting the light-emitting component 133L radiating incandescent light color (L) light is set to " 1 ", and represents the epiphysin degree of suppression in each mixed light ratio with relative value.The example of result of study as shown in Figure 10.

And, present inventor by radiating the light-emitting component 133R of red (R) light, the power of the light-emitting component 133G of green (G) light of radiation is set to constant, and when dim light is carried out to the light-emitting component 133L of radiation incandescent light color (L) light, the relation between the mixed light ratio of light-emitting component 133L and the relative value of epiphysin degree of suppression is studied.Epiphysin degree of suppression when only lighting the light-emitting component 133L radiating incandescent light color (L) light is set to " 1 ", and represents the epiphysin degree of suppression in each mixed light ratio of light-emitting component 133L with relative value.The example of result of study as shown in figure 11.

Chart according to Figure 10 and Figure 11, if make the mixed light of the light-emitting component 133L of incandescent light color (L) light of radiation than declining, then epiphysin degree of suppression also declines.At this, the ratio of the luminous flux of the light that mixed light will mix than expression.

Therefore, in " help of sleeping " pattern, the control part 115 of embodiment performs following control: after the glow color colour mixture of incandescent light color (L), red (R), green (G), only performs dim light to the light-emitting component 133L of radiation incandescent light color (L) light and controls.Then, when the power of light-emitting component 133L becomes below predetermined value, control part 115 performs the control making light-emitting component 133G and light-emitting component 133R dim light.

If the dimming ratio (mixed light ratio) radiating the light-emitting component 133L of incandescent light color (L) light becomes " 0.4 ", then mixed light departs from the domain of definition of correlated colour temperature.If mixed light departs from the domain of definition of correlated colour temperature, then likely occur that light color seems factitious phenomenon.Therefore, control part 115 more preferably performs following control: if dropped to " 0.5 " by the mixed light of light-emitting component 133L ratio, then maintain the mixed light ratio of light-emitting component 133L, light-emitting component 133G, light-emitting component 133R, namely maintain light color and carry out dim light, thus turning off the light at h.d..

According to embodiment, the suitable light space conformed to living scene can be presented.That is, relatively reduce the blue light components comprised in the mixed light of " help of sleeping " pattern, reduce epiphysin degree of suppression within doors, thus people within doors can be impelled to sleep soundly.And, if the power of light-emitting component 133L becomes below predetermined value, then make light-emitting component 133G and light-emitting component 133R dim light, thus make blue light components be reduced to below predetermined value, maintain the light color that inhibit sense of discomfort afterwards.And, by the mixed light in " help of sleeping " pattern, average color can be provided to reproduce and to evaluate the higher light of number, thus the light color of indoor can be remained on natural light color.

As described in Fig. 3 (a) and Fig. 3 (b), the LED body the being installed on inner circumferential side row light-emitting component 133L that uses glow color to be incandescent light color (L), glow color are the light-emitting component 133D of color of sunshine (D).The embodiment of the LED body of outer circumferential side row is identical with the embodiment of the LED body that inner circumferential side arranges.The light-emitting component 133B that the light-emitting component 133G that the light-emitting component 133R that the LED body being installed on middle column uses glow color to be red (R), glow color are green (G), glow color are blue (B).

Therefore, in " help of sleeping " pattern, even if extinguish the light-emitting component 133D of radiation color of sunshine (D) light and the light-emitting component 133B of blue (B) light of radiation, the decline of the tone before the light-off of h.d. also can be suppressed by distribution controls portion 140.Therefore, it is possible to the glow color of the incandescent light color (L) of the incandescent light color (L) of inner circumferential side row, the redness (R) of middle column and green (G), outer circumferential side row is carried out colour mixture, and brightness disproportionation can not be produced.

Then, with reference to accompanying drawing, the example of the control performed by the control part 115 of embodiment is described.

If be set as " help of sleeping " pattern, then the control part 115 of embodiment performs following control: the mixed light of the chroma point A of radiation shown in Figure 12.The correlated colour temperature of the mixed light of chroma point A is such as 2200K.Chroma point A is such as " 0 " relative to the deviation delta uv of black body locus.Then, control part 115 performs following control: make the mixed light of chroma point A become the mixed light of the chroma point B shown in Figure 12 along with the process of time.The coordinate (x, y) of chroma point B is such as (0.62,0.36).The color of the mixed light of chroma point B is orange-yellow.

So, when being set as " help of sleeping " pattern, the control part 115 of embodiment performs following control: on radiation xy chromatic diagram be within ± 0.02 and the mixed light (the 1st light) of the 1st chroma point that can show with correlated colour temperature relative to the deviation delta uv of black body locus.Then, control part 115 performs following control: make the mixed light of the 1st chroma point be more than 0.32 and less than 0.45, x coordinate is more than 0.51 and the mixed light (the 2nd light) of the 2nd chroma point of the A2 inside, region surrounded by spectrum locus along with the process y coordinate become on xy chromatic diagram of time.

According to this example, control part 115 makes the mixed light of the 1st chroma point become the mixed light of the 2nd chroma point, thus the low light of the color temperature making more not easily to affect sleep becomes the light that blue light components comparatively speaking reduces further.Such as, control part 115 performs following control: the mixed light radiating the 1st chroma point before going to bed 1 hour, makes the mixed light of the 1st chroma point become the mixed light of the 2nd chroma point gradually, and reduce brightness from before going to bed 10 minutes, and going to bed, the moment turns off the light.Thus, there is in the initial stage radiation of " help of sleeping " pattern the light of the colourity in the domain of definition of correlated colour temperature, thus suppress apparent sense of discomfort.And, from initial stage of " help of sleeping " pattern to sleep moment (going to bed the moment), the mixed light of the 1st chroma point gradually becomes the mixed light of the 2nd chroma point in chroma areas A2 that redness thickens, thus can not suppress to promote the hormone of sleep and the secretion of epiphysin, can natural sleep be promoted.

Figure 13 (a) is the example of the relative spectral power distribution of light before control part 115 changes light color.Figure 13 (b) is the example of the relative spectral power distribution of light after control part 115 changes light color.Transverse axis in chart shown in Figure 13 (a), Figure 13 (b) represents wavelength (nanometer: nm).The longitudinal axis in chart shown in Figure 13 (a), Figure 13 (b) represents relative energy.

When being set as " help of sleeping " pattern, the control part 115 of embodiment performs following control: the 1st mixed light (the 1st light) represented in the relative spectral power distribution of radiation Figure 13 (a).If the maximum of the energy of spatial distribution be set to " 1 ", then the maximum of the energy of the 1st mixed light in below 500nm wavelength region is less than 0.25.In the example of the relative spectral power distribution shown in Figure 13 (a), the maximum of the energy of the 1st mixed light in below 500nm wavelength region is " 0.14 ".

Then, control part 115 performs following control: along with the process of time, the 2nd mixed light (the 2nd light) the 1st mixed light being become represent in the relative spectral power distribution of Figure 13 (b).If the maximum of the energy of spatial distribution be set to " 1 ", then the maximum of the energy of the 2nd mixed light in below 500nm wavelength region is less than 0.1.In the example of the relative spectral power distribution shown in Figure 13 (b), the maximum of the energy of the 2nd mixed light in below 500nm wavelength region is " 0.002 ".

According to this example, control part 115 becomes the 2nd mixed light by making the 1st mixed light, thus the low light of the color temperature making more not easily to affect sleep becomes the light that blue light components comparatively speaking reduces further.Such as, control part 115 performs following control: before going to bed 1 hour, radiate the 1st mixed light, from before going to bed 10 minutes, then make the 1st mixed light gradually become the 2nd mixed light and reduce brightness, and going to bed, the moment turns off the light.Thus, the blue light components comprised in the spectrum due to the 1st mixed light is below predetermined value, thus compares the secretion being difficult to suppress epiphysin.And, from initial stage of " help of sleeping " pattern to sleep moment (going to bed the moment), make the 1st mixed light become the 2nd mixed light, therefore, it is possible to realize the light to suppressing the bad influence of epiphysin to reduce further.

In xy chromatic diagram, radiate the chromaticity coordinate of the light-emitting component 133L of incandescent light color (L) light, the chromaticity coordinate of light-emitting component 133D of radiation color of sunshine (D) light, the chromaticity coordinate of the light-emitting component 133R of red (R) light of radiation, the chromaticity coordinate of the light-emitting component 133G of green (G) light of radiation, the light-emitting component 133B of blue (B) light of radiation chromaticity coordinate such as shown in Figure 14 (a).

At this, become the control procedure of the lighting state of another mixed light ratio in execution from the lighting state of any mixed light ratio, according to the mixed light ratio of each light-emitting component, radiate the light of unnatural color sometimes.Such as, as shown in Figure 14 (b), the situation becoming the 2nd lighting state from the 1st lighting state is described.In the 1st lighting state, the light-emitting component 133B of radiation blueness (B) light is only made to light.In the 2nd lighting state, the light-emitting component 133L of the light-emitting component 133R of radiation redness (R) light and radiation incandescent light color (L) light is lighted.That is, in the 2nd lighting state, the mixed light of radioluminescence element 133R and light-emitting component 133L.

When becoming the 2nd lighting state from the 1st lighting state, if change all light modulations of light-emitting component 133L, light-emitting component 133R, light-emitting component 133B simultaneously, then light color likely can by the aubergine region of the high chroma the region A3 as shown in Figure 14 (b).Then, the light of the unnatural color running counter to user's intention can be radiated.

To this, in embodiments, first, from the 1st lighting state, light-emitting component 133L is made to light (the 1st control procedure).Then, light-emitting component 133B is made to turn off the light (the 2nd control procedure).That is, control part 115 performs following control: when becoming the 2nd lighting state from the 1st lighting state, according to the kind of light-emitting component, carry out light modulation across the time difference to each light-emitting component.

Thus, become the control procedure of the lighting state of another mixed light ratio from the lighting state of any mixed light ratio in execution, the radiation of unnatural color of light can be suppressed.

Such as, control part 115 is from when only making the state of chromatic colour light source igniting become the state only making white light source light, or from when only making the state of chromatic colour light source igniting become to make the state of white light source and chromatic colour light source igniting, before control chromatic colour light source, start the control performing white light source.

Such as, control part 115 from when only making the state of chromatic colour light source igniting become another state only making chromatic colour light source igniting, make white light source light after perform the control of chromatic colour light source, perform the control that white light source is turned off the light afterwards.

Thus, before the control of chromatic colour light source, start the control performing white light source, therefore, even if the mixed light state of chromatic colour light source changes afterwards, tone also can be suppressed to change in high chroma region.Therefore, it is possible to suppress the radiation of unnatural color of light.

Such as, control part 115 from the state of white light source and chromatic colour light source igniting is become make in white light source and chromatic colour light source at least any one light another state time, before control white light source, start the control performing chromatic colour light source.

Such as, control part 115, when becoming from the state only making white light source light the state only making chromatic colour light source igniting, started the control performing chromatic colour light source before control white light source.

Thus, under the state lighted making white light source, before control white light source, start the control performing chromatic colour light source, therefore, it is possible to suppress tone to change in the region of high chroma.Therefore, it is possible to suppress the radiation of unnatural color of light.

In L*a*b* colour system, the chromaticity coordinate of the chromaticity coordinate of the light-emitting component 133R of red (R) light of radiation, the chromaticity coordinate of the light-emitting component 133G of green (G) light of radiation, the light-emitting component 133B of blue (B) light of radiation such as shown in figure 15.

As described in Figure 14 (a) and Figure 14 (b), become the implementation of the control of the lighting state of another mixed light ratio from the lighting state of any mixed light ratio, according to the mixed light ratio of each light-emitting component, radiate the light of unnatural color sometimes.Such as, as shown in figure 15, the situation of the state that the light-emitting component 133B that the state lighted the light-emitting component 133R from red (R) light of radiation becomes blue (B) light of radiation lights is described.

When becoming from the state only making light-emitting component 133R light the state only making light-emitting component 133B light, if reduce the power of light-emitting component 133R gradually, improve the power of light-emitting component 133B gradually, then the 1st control procedure is as shown in figure 15 such, light color is in L*a*b* colour system, compare with the straight line of the chromaticity coordinate of light-emitting component 133B with the chromaticity coordinate connecting light-emitting component 133R, change slightly toward circumference.Then, in the 1st control procedure, light color, through bright-coloured aubergine, may bring factitious impression to user.

To this, in embodiments, become the process of the state only making light-emitting component 133B light from the state only making light-emitting component 133R light, execution adds the control of green (G), so that by the 2nd control procedure, the 2nd control procedure compared with the 1st control procedure via the region of the initial point closer to L*a*b* colour system.Namely, control part 115 performs following control: when becoming the 2nd lighting state from the 1st lighting state, the colourity of the L*a*b* colour system of the light color presented in change procedure is positioned at compare with the straight line of the chromaticity coordinate of the 2nd lighting state, closer to the region of initial point with the chromaticity coordinate of connection the 1st lighting state.

Thus, in the change procedure of lighting state, because light color is through the lower region of colourity, thus can relax apparent not natural sense.In the example shown in Figure 15, in the 2nd control procedure, light color becomes blue (B) from red (R) via reddish white and bluish white.Therefore, it is possible to suppress to bring factitious impression to user.

In this example embodiment, the situation that have selected " beautiful " pattern, " comfortable " pattern or " arenas " pattern is described.

User such as selects " beautiful " pattern (step S101) by " beautiful " button 181 of remote controller 180.Or user such as selects " comfortable " pattern (step S103) by " comfortable " button 182 of remote controller 180.Or user such as selects " arenas " pattern (step S105) by " arenas " button 183 of remote controller 180.

Then, control part 115 judges whether setting timing function (step S107).Timing function in this example refers to so-called " timing closing function ", makes the function that light-emitting component 133 extinguishes after being through the scheduled time.If do not set timing function (step S107: no), then control part 115 continues to judge whether setting timing function (step S107).

On the other hand, if be set with timing function (step S107: yes), then control part 115 performs " help of sleeping " pattern.The control performed in " help of sleeping " pattern is such as described in Fig. 9 ~ Figure 13 (b).Then, control part 115 makes all light-emitting components 133 turn off the light (step S111).So, in the example shown in Figure 16, lighting pattern (the 2nd lighting pattern) that adjust in advance in the lighting pattern that have selected beyond " help of sleeping " pattern and to the luminous power of each glow color, if set timing function, then control part 115 performs following control: via " help of sleeping " pattern, all light-emitting components 133 are turned off the light.In other words, when the lighting pattern adjusted in advance in the lighting pattern that have selected beyond " help of sleeping " pattern and to the luminous power of each glow color, if be set with timing function, then control part 115 performs following control: from selected lighting mode shifts to " help of sleeping " pattern.This control is different from simple control of " beautiful " pattern, " comfortable " pattern or " arenas " the lighting dim light of pattern being turned off the light.

So, timing function carries out work via not hindering " help of the sleeping " pattern of sleep, thus, even if be set as the lighting pattern (such as " beautiful " pattern) such as with the effect of waking up, also can promote to fall asleep.Therefore, it is possible to provide the light of the bad influence that inhibit sleep.

In this example, the situation that have selected " beautiful " pattern, " comfortable " pattern or " arenas " pattern is described.

User such as selects " beautiful " pattern (step S121) by " beautiful " button 181 of remote controller 180.Or user such as selects " comfortable " pattern (step S123) by " comfortable " button 182 of remote controller 180.Or user such as selects " arenas " pattern (step S125) by " arenas " button 183 of remote controller 180.

Then, control part 115 makes to control separately to become impossible (step S127).That is, when have selected the lighting pattern adjusted in advance the luminous power of each glow color, control part 115 is forbidden adjusting the light modulation ratio of each glow color and is changed the function of the luminous power of each glow color.Thereby, it is possible to suppress the effect that cannot obtain based on specific toning ratio.In other words, the set information to each lighting pattern that the luminous power of each glow color adjusts in advance can be kept.

In addition, when have selected " help of sleeping " pattern, in the scope of the incandescent light color (L) can lighted in " help of sleeping " pattern, red (R), green (G), the light modulation of each glow color is changed to the luminous power of each glow color than adjusting.That is, in " help of sleeping " pattern, can, in the scope of incandescent light color (L), red (R), green (G), light modulation and toning be made to become possibility.

Then, control part 115 judges whether to set " full light " pattern (step S129).So-called " full light " pattern refers to and the luminous power of all light-emitting components 133 of the incandescent light color (L) in light source portion 130 and color of sunshine (D) to be set to maximum and to make the pattern of glow color colour mixture.High and the light of the daylight colour system that color rendition is superior of " full light " pattern performance color rendering properties.When not being set as " full light " pattern (step S129: no), control part 115 continues to judge whether to set " full light " pattern (step S129).

On the other hand, such as, when user sets " full light " pattern by " full light " button 189 (with reference to Fig. 8 (a) and Fig. 8 (b)) of remote controller 180 (step S129: yes), control part 115 was removed forbidding of controlling separately, made to control separately to become possibility.In addition, control part 115 except remove when being set as " full light " pattern to control separately forbid except, also can be removed forbidding of controlling separately when selected lighting pattern (" beautiful " pattern, " comfortable " pattern or " arenas " pattern) removes.Thus, user, such as by " R " button 185 of remote controller 180, " G " button 186 and " B " button 187, can adjust the light modulation ratio of each glow color and change the luminous power of each glow color.

In addition, be not only limited to this example, when have selected " beautiful " pattern, " comfortable " pattern or " arenas " pattern, in the scope of each lighting pattern, redness (R), green (G), blue (B) can be controlled separately.Thereby, it is possible in the scope of each lighting pattern, carry out the inching of redness (R), green (G), blue (B).

Or, when have selected " beautiful " pattern, " comfortable " pattern or " arenas " pattern, can control separately untapped glow color in each lighting pattern.Thereby, it is possible to carry out the inching of untapped glow color in each lighting pattern.

If user such as selects timing function (step S141) by " closing for 30 minutes " button 188 (with reference to Fig. 8 (a) and Fig. 8 (b)) of remote controller 180, then control part 115 performs following control: in main light source and secondary light source, first make main light source turn off the light (step S143).Such as, control part 115 makes light-emitting component 133L and light-emitting component 133D turn off the light.Then, control part 115 performs the control (step S145) that secondary light source is turned off the light.Such as, control part 115 makes light-emitting component 133R, light-emitting component 133G and light-emitting component 133B turn off the light.

In addition, timing function as described in Figure 16.

Such as, when radiation has the mixed light of incandescent light color (L) light, redness (R) light, green (G) light, if user such as selects timing function by " closing for the 30 minutes " button 188 of remote controller 180, then control part 115 makes the light-emitting component 133L in the light-emitting component 133G of the light-emitting component 133R of the light-emitting component 133L of incandescent light color (L) light of radiation, red (R) light of radiation, green (G) light of radiation first turn off the light.Then, control part 115 makes light-emitting component 133R and light-emitting component 133G turn off the light.

Thus, because the illumination of main light source is usually high than the illumination of secondary light source, thus by first making the illumination of main light source decline, before light-off, making the secondary light source igniting that illumination is relatively low, lights-out operations can be carried out under relatively low illumination.Therefore, it is possible to provide the light of the bad influence that inhibit sleep.

If user such as selects timing function (step S151) by " closing for the 30 minutes " button 188 of remote controller 180, then control part 115 performs following control: in main light source and secondary light source, first make secondary light source turn off the light (step S153).Such as, control part 115 makes light-emitting component 133R, light-emitting component 133G and light-emitting component 133B turn off the light.Then, control part 115 performs the control (step S155) that main light source is turned off the light.Such as, control part 115 makes light-emitting component 133L and light-emitting component 133D turn off the light.

In addition, timing function as described in Figure 16.

Such as, when radiation has the mixed light of incandescent light color (L) light, redness (R) light, green (G) light, if user such as selects timing function by " closing for the 30 minutes " button 188 of remote controller 180, then control part 115 makes the light-emitting component 133R in the light-emitting component 133G of the light-emitting component 133R of the light-emitting component 133L of incandescent light color (L) light of radiation, red (R) light of radiation, green (G) light of radiation and light-emitting component 133G first turn off the light.Then, control part 115 makes light-emitting component 133L turn off the light.

Thus, such as, when the correlated colour temperature of the mixed light of red (R) light, green (G) light brings sense of discomfort before light-off, by making light-emitting component 133R and light-emitting component 133G first turn off the light, the sense of discomfort before light-off can be eliminated.Now, the light of incandescent light color (L) can be provided before light-off.

In this example, the situation light-emitting component 133G of the light-emitting component 133L of radiation incandescent light color (L) light, the light-emitting component 133R radiating red (R) light, green (G) light of radiation being in light-off state is described.

The component 116 being arranged at the inside of the underframe of power supply unit 110 comprises not shown sensor.As sensor, such as, there is the detection force-feeling sensor whether someone exists.As force-feeling sensor, such as, there is the sensor using ultrared sensor, use hyperacoustic sensor, use microwave.In addition, sensor also can be arranged on appliance body 120.

According to the opinion of present inventor, color temperature or the lower light color of correlated colour temperature can be difficult to hinder sleepiness.Therefore, before color temperature or the lower light color of correlated colour temperature are more suitable for going to bed or the illumination of the short period at night.But, in order to realize color temperature or the lower light color of correlated colour temperature, need to use color temperature or the lower light-emitting component of correlated colour temperature.

To this, in the example shown in Figure 20, when the light-emitting component 133G of the light-emitting component 133L of radiation incandescent light color (L) light, the light-emitting component 133R radiating red (R) light, green (G) light of radiation is in light-off state (step S161), control part 115 judges whether force-feeling sensor detects human body (step S163).If force-feeling sensor does not detect human body (step S163: no), then control part 115 continues to judge whether force-feeling sensor detects human body (step S163).

On the other hand, when human body sensor detects human body (step S163: yes), control part 115 makes the light-emitting component 133R of the light-emitting component 133L of incandescent light color (L) light of radiation, red (R) light of radiation, the light-emitting component 133G of green (G) light of radiation lights, and becomes the lighting state that correlated colour temperature is lower than the correlated colour temperature under the state only making light-emitting component 133L light.Such as, when force-feeling sensor detects human body (step S163: yes), pattern that control part 115 performs " help of sleeping ".

Thus, before bedtime or the operation of the short period at night time, ligthing paraphernalia 100 human body involved by embodiment and automatically lighting.The correlated colour temperature of the light color lighted is lower than the correlated colour temperature of the light-emitting component 133L of radiation incandescent light color (L) light.Therefore, before bedtime or the operation of the short period at night time, the light color being difficult to hinder sleepiness can be realized.Such as, user, when going to toilet etc. night, does not impel and wakes up, and suppresses to hinder and again go to bed.

Then the illuminator of the ligthing paraphernalia 100 possessed involved by embodiment and testing agency is described.

Illuminator possesses: the ligthing paraphernalia 100 described in Fig. 1 (a) ~ Figure 20 and testing agency.As testing agency, such as, there are force-feeling sensor, biology sensor, imageing sensor, load transducer etc.As force-feeling sensor, such as, there is the sensor using ultrared sensor, use hyperacoustic sensor, use microwave.As biology sensor, there is the sensor of the biological informations such as detection pulse, electrocardio, body temperature, body move, blood pressure.As imageing sensor, such as, there is the imageing sensor with camera etc. of the activity of human body and the trend of eyes etc.

Illuminator involved by embodiment by sensor detect occupant go to bed before in the bedroom in action, and according to the testing result of sensor, after a predetermined time, ligthing paraphernalia 100 is turned off the light automatically.Such as, if sensor detect occupant go to bed before action, then illuminator makes ligthing paraphernalia 100 start to turn off the light after 5 minutes, spends such as 10 minutes of degree that occupant can not be taken notice of to make ligthing paraphernalia 100 dim light and automatically turns off the light.Such as comprise as " action before going to bed ": occupant enters the action in bedroom, occupant sits action in bed, the action of sleep, the trend of eyes, the action of wearing nightwear, the action etc. out from bathroom when feeling sleepy.

Thus, due to sensor detect occupant go to bed before action, thus occupant is without the need to carrying out specific operation, automatically turns off the light after can making ligthing paraphernalia 100 after a predetermined time.

Other illuminator involved by embodiment possesses: the multiple ligthing paraphernalias 100 as described in Fig. 1 (a) ~ Figure 20.Multiple ligthing paraphernalia 100 is respectively arranged with and controls address separately.Control part 115 across the time difference control multiple ligthing paraphernalia 100 light modulation and toning at least any one.
