As shown in Fig. 4 (a), distribution controls portion 140 is fixed on apparatus body 120, and covering luminous element 133 and through 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, in the inner circumferential side in distribution controls portion 140, be formed with the protuberance 145 corresponding with the electrical connection section of substrate 131 and power suppling part.Namely protuberance 145 is circumferentially formed as the size longer than connector size in ring-type direction.That is, being constructed by of distribution controls portion 140 is rotated and is loaded and unloaded on apparatus body 120, therefore, with when distribution controls portion 140 rotates and electrical connection section CN and electric wire 135 without the mode of interfering, there is protuberance 145 in a circumferential direction that grow than connector size.

Distribution controls portion 140 has lens (1ens) portion 141.Lens section 141 comprises part 1 141a, part 2 141b and the 3rd part 141c.And, between part 1 141a with the 3rd part 141c, between part 2 141b and the 3rd part 141c, the region of the closed end portion 141e corresponding with substrate 131 of the inner circumferential side at part 1 141a and the outer circumferential side at part 2 141b, be formed with light diffusion part 141f.Light diffusion part 141f is such as formed by bestowing relief pattern.Light diffusion part 141f also can utilize additive methods such as pasting diffusion sheet (sheet) and be formed.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 the row of inner circumferential side and the luminous intensity distribution of the light-emitting component 133 of the row of control inner circumferential side.Part 2 141b 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)) in middle column and controls the luminous intensity distribution of the light-emitting component 133 of middle column.3rd part 141c covers the light-emitting component 133 (being light-emitting component 133L and light-emitting component 133D in the example of Fig. 4 (b)) of the row of outer circumferential side and the luminous intensity distribution of the light-emitting component 133 of the row of control outer circumferential side.That is, the distribution controls portion 140 of embodiment controls the luminous intensity distribution of the light-emitting component 133 being disposed in each row independently for each row.

Thus, the color inequality on lower surface (light-emitting area) 150a of cover body 150 and brightness disproportionation can be reduced, make colourity and brightness uniformity.

Herein, when the light-emitting component 133 of the light-emitting component 133 of the row by outer circumferential side and the row of inner circumferential side is set to non-lighting and only the light-emitting component 133 of middle column is set to lighting, according to the shape of lens section 141, sometimes, the lower surface 150a of cover body 150 can produce bright line.More specifically, if shown in the arrow A such as shown in Fig. 4 (b) 11 and arrow A 12, from the Transmission light part 2 141b that the light-emitting component 133 of middle column sends, and be incident in part 1 141a and the 3rd part 141c at least any one, then on the lower surface 150a of cover body 150, produce bright line sometimes.

With reference to accompanying drawing, " sleep is auxiliary " pattern is further described.

Point photodistributed curve map relatively of the light that Fig. 9 sends for light-emitting component under expression " sleep is auxiliary " pattern.

The transverse axis of the curve map shown in Fig. 9 represents wavelength (nanometer: nm).The longitudinal axis of the curve map shown in Fig. 9 represents relative energy.Relative light splitting distribution shown in Fig. 9 represents that the light-emitting component 133L of the light by sending light bulb color (L), the light-emitting component 133R sending the light of redness (R) and the light-emitting component 133G of light sending green (G) carry out the example of mixed light with the ratio of " 0.83: 0.12: 0.05 ".

There is in the wave-length coverage that the light splitting of the mixed light sent under " sleep auxiliary " pattern is distributed in more than 600nm, below 650nm the peak value of energy.In point Light distribation relatively shown in Fig. 9, there is the peak value of energy when wavelength is 635nm.

If the maximum of point photodistributed energy is set to " 1 ", then the mixed light sent under " sleep is auxiliary " pattern being more than or equal to 380nm, the peak value of the energy be less than or equal in the wave-length coverage of 500nm is for being less than or equal to 0.25.In the relatively point Light distribation shown in Fig. 9, being more than or equal to 380nm, the relative energy of the peak value be less than or equal in the wave-length coverage of 500nm is " 0.2 ".If the maximum of point photodistributed energy is set to " 1 ", then the mixed light sent under " sleep is auxiliary " pattern being more than or equal to 530nm, the peak value of the energy be less than or equal in the wave-length coverage of 600nm is for being more than or equal to 0.25, being less than or equal to 0.6.In the relatively point Light distribation shown in Fig. 9, being more than or equal to 530nm, the relative energy of the peak value be less than or equal in the wave-length coverage of 600nm is " 0.48 ".

The average color rendering index (Ra) of the light of the light bulb color (L) that light-emitting component 133L sends is " 84 ".The average color rendering index (Ra) of the mixed light of described ratio (0.83: 0.12: 0.05) is " 93 ".Namely, with send light bulb color (L) light situation compared with, utilization send the light of light bulb color (L) light-emitting component 133L, send the light-emitting component 133R of the light of redness (R) and send the mixed light of light-emitting component 133G of light of green (G), average color rendering index (Ra) improves.

Table 1 is for carry out illustrative table to the relation between mixed light ratio and epiphysin degree of suppression.

This novel creator studies for light-emitting component 133L, the light-emitting component 133R sending the light of redness (R) of light and the relation sent between the mixed light ratio (light modulation than) of light-emitting component 133G of light of green (G) and epiphysin degree of suppression sending light bulb color (L).About epiphysin degree of suppression, the epiphysin effect curve of sensitivity of Bu Lainade (Brainard) is set to Brainard (λ) and calculates according to following formula.

Brainard (λ) × relatively divide Light distribation/V (λ) × relatively divide Light distribation ... formula (1)

" V (λ) " in formula (1) is for photopic vision (photopic) standard is than visual sense degree.And, epiphysin degree of suppression when only making the light-emitting component 133L lighting of the light sending light bulb color (L) is set to " 1 ", with relative value represent each mixed light than under epiphysin degree of suppression.The example of result of study is as shown in table 1.

And, this novel creator about the light by sending redness (R) light-emitting component 133R, and the output of light-emitting component 133G of light that sends green (G) be set to fixing and make to send the light-emitting component 133L dim light of the light of light bulb color (L) time, relation between the mixed light ratio of light-emitting component 133L and epiphysin degree of suppression relative value studies.Epiphysin degree of suppression when only making the light-emitting component 133L lighting of the light sending light bulb color (L) is set to " 1 ", with relative value represent each mixed light of light-emitting component 133L than under epiphysin degree of suppression.The example of result of study as shown in Figure 10.

Curve map according to the table shown in table 1 and Figure 10, send the mixed light of the light-emitting component 133L of the light of light bulb color (L) if make than declining, then epiphysin degree of suppression can decline.Herein, so-called mixed light is than the ratio of the light beam of the light of expression mixing.

Therefore, the control part 115 of embodiment performs following control under " sleep is auxiliary " pattern: after the illuminant colour colour mixture of light bulb color (L), red (R) and green (G), only make the light-emitting component 133L dim light of the light sending light bulb color (L).Then, when the output of light-emitting component 133L reaches below setting, 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) sending the light-emitting component 133L of the light of light bulb color (L) becomes " 0.4 ", then mixed light can be in outside the defined range of correlated colour temperature.Time outside the defined range that mixed light is in correlated colour temperature, the photochromic of outward appearance may become not nature.Therefore, more preferably, control part 115 performs following control: if make the mixed light of light-emitting component 133L ratio drop to " 0.5 ", then when keep the mixed light of the mixed light ratio of light-emitting component 133L, light-emitting component 133G when light-emitting component 133R mixed light than, namely keep photochromic when dim light, and when h.d. is turned off the light.

According to embodiment, the suitable light space conformed to living scene can be presented.That is, by making the composition of blue light contained in the mixed light under " sleep is auxiliary " pattern relatively reduce and reduce the epiphysin degree of suppression of indoor occupant, can promote to sleep soundly.And, when the output of light-emitting component 133L reaches below setting, by carrying out dim light to light-emitting component 133G and light-emitting component 133R, can make the composition of blue light be reduced to below setting after keep suppressed the photochromic of incongruity.And then, utilize the mixed light under " sleep auxiliary " pattern, the light that average color rendering index is relatively high can be provided, and can make indoor photochromic remain naturally photochromic.

As above about Fig. 3 (a) and Fig. 3 (b) explanation as described in, in the LED of row being installed on inner circumferential side, the light-emitting component 133L that use illuminant colour is light bulb color (L) and illuminant colour are the light-emitting component 133D of color of sunshine (D).The installation homomorphosis of the LED of the installation form of the LED of the row of outer circumferential side and the row of inner circumferential side.In the LED being installed on middle column, use that illuminant colour is the light-emitting component 133R of red (R), illuminant colour be the light-emitting component 133G of green (G) and illuminant colour is the light-emitting component 133B of blueness (B).

Thus, under " sleep is auxiliary " pattern, even if the light-emitting component 133B of the light-emitting component 133D sending the light of color of sunshine (D) and the light that sends blueness (B) is turned off the light, also can by distribution controls portion 140 suppress h.d. turn off the light before tone decline.Therefore, illuminant colour colour mixture when not producing brightness disproportionation of the light bulb color (L) of the redness (R) of the light bulb color of the row of inner circumferential side (L), middle column and the row of green (G) and outer circumferential side can be made.

Then, with reference to accompanying drawing, the example of the control that the control part 115 for embodiment performs is described.

If be set as " sleep is auxiliary " pattern, then the control part 115 of embodiment performs following control: the correlated colour temperature sending the mixed light of the mixed light chroma point A of the chroma point A shown in Figure 11 is such as 2200K.The deviation delta uv of chroma point A and black body radiation track is such as " 0 ".Then, control part 115 performs following control: the mixed light of chroma point A is changed to 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 mixed light look of chroma point B is orange (orange) look.

Like this, if be set as " sleep auxiliary " pattern, then the control part 115 of embodiment performs following control: to send on xy chromatic diagram be the 1st chroma point within ± 0.02 with the deviation delta uv of black body radiation track, the mixed light (the 1st light) of the 1st chroma point that can embody under correlated colour temperature.Then, control part 115 performs following control: the mixed light of the 1st chroma point is changed to the mixed light of the 2nd chroma point (the 2nd light) along with the process of time, the mixed light of the 2nd chroma point be positioned on xy chromatic diagram y coordinate for being more than or equal to 0.32, be less than or equal to 0.45 and the inside of region A2 that surrounds for region A2, the i.e. spectrum locus being more than or equal to 0.51 of x coordinate.

According to this example, the mixed light of control part 115 by making the mixed light of the 1st chroma point be changed to the 2nd chroma point, and make the light of not easily nypnapagogic low color temperature relatively be changed to the relative lower light of composition of blue light.Such as, control part 115 performs following control: the mixed light sending the 1st chroma point before bedtime for 1 hour, within 10 minutes, makes the mixed light of the 1st chroma point be gradually varied to the mixed light of the 2nd chroma point and brightness is declined before bedtime, and going to bed, the moment turns off the light.Thus, at the initial stage of " sleep is auxiliary " pattern, send the light of the colourity had in the defined range of correlated colour temperature, the incongruity of outward appearance can be suppressed like this.And, by carving (going to bed the moment) from the initial stage of " sleep is auxiliary " pattern to the dormancy Time that sleeps, the mixed light of the 1st chroma point is made to be gradually varied to the mixed light of the 2nd chroma point in the region A2 of the colourity that redness thickens, the secretion of the epiphysin as the hormone (hormone) promoting sleep can not be suppressed, naturally sleep can be promoted.

Figure 12 (a) makes the relatively point photodistributed example of the light before photochromic change for control part 115.Figure 12 (b) makes the relatively point photodistributed example of the light after photochromic change for control part 115.The transverse axis of the curve map shown in Figure 12 (a) and Figure 12 (b) represents wavelength (nanometer: nm).The longitudinal axis of the curve map shown in Figure 12 (a) and Figure 12 (b) represents relative energy.

If be set as " sleep is auxiliary " pattern, then the control part 115 of embodiment performs following control: point the 1st mixed light (the 1st light) shown in Light distribation relatively sending Figure 12 (a).If the maximum of point photodistributed energy be set to " 1 ", then the maximum of the energy of the 1st mixed light in the wavelength domain being less than or equal to 500nm is for being less than or equal to 0.25.In point photodistributed example relatively shown in Figure 12 (a), the maximum of the energy of the 1st mixed light in the wavelength domain being less than or equal to 500nm is " 0.14 ".

Then, control part 115 performs following control: along with the process of time, and the 1st mixed light is changed to point the 2nd mixed light (the 2nd light) shown in Light distribation relatively of Figure 12 (b).If the maximum of point photodistributed energy be set to " 1 ", then the maximum of the energy of the 2nd mixed light in the wavelength domain being less than or equal to 500nm is for being less than or equal to 0.1.In point photodistributed example relatively shown in Figure 12 (b), the maximum of the energy of the 2nd mixed light in the wavelength domain being less than or equal to 500nm is " 0.002 ".

According to this example, control part 115 is changed to the 2nd mixed light by making the 1st mixed light, and makes the light of not easily nypnapagogic low color temperature relatively be changed to the relative lower light of composition of blue light.Such as, control part 115 performs following control: within 1 hour, send the 1st mixed light before bedtime, within 10 minutes, makes the 1st mixed light be gradually varied to the 2nd mixed light and brightness is declined before bedtime, and going to bed, the moment turns off the light.Thus, because the composition of blue light contained in point Light distribation of the 1st mixed light is below setting, so relatively not easily suppress the secretion of epiphysin.And, making the 1st mixed light be changed to the 2nd mixed light by carving (going to bed the moment) from the initial stage of " sleep is auxiliary " pattern to the dormancy Time that sleeps, the light less to the harmful effect of epiphysin suppression can be realized.

The chromaticity coordinate of light-emitting component 133B of light on xy chromatic diagram, send the chromaticity coordinate of the light-emitting component 133L of the light of light bulb color (L), send the chromaticity coordinate of the light-emitting component 133D of the light of color of sunshine (D), send the chromaticity coordinate of the light-emitting component 133R of the light of redness (R), sending the chromaticity coordinate of the light-emitting component 133G of the light of green (G) and send blueness (B) is such as shown in Figure 13 (a).

Herein, be changed to the process of the control of the lighting state of other mixed light ratios in execution from the lighting state of arbitrary mixed light ratio, according to the mixed light ratio of each light-emitting component, send the light of factitious color sometimes.Such as, the situation being changed to the 2nd lighting state from the 1st lighting state shown in such as Figure 13 (b) is described.Under the 1st lighting state, only there is the light-emitting component 133B lighting of the light sending blueness (B).Under the 2nd lighting state, the light-emitting component 133L lighting of the light-emitting component 133R sending the light of redness (R) and the light sending light bulb color (L).That is, under the 2nd lighting state, the mixed light of light-emitting component 133R and light-emitting component 133L is sent.

When being changed to the 2nd lighting state from the 1st lighting state, if all light modulations of light-emitting component 133L, light-emitting component 133R and light-emitting component 133B change simultaneously, then the photochromic mauve region such as may passing the contour chroma of region A3 shown in Figure 13 (b).Like this, the light of the factitious color that also non-user is wanted may be sent.

To this, in embodiment, first, from the 1st lighting state, light-emitting component 133L lighting (the 1st control procedure).Then, light-emitting component 133B turns off the light (the 2nd control procedure).That is, control part 115 performs following control: when being changed to the 2nd lighting state from the 1st lighting state, carries out light modulation according to the kind of light-emitting component with the time difference to each light-emitting component.

Thus, be changed to the process of the control of the lighting state of other mixed light ratios in execution from the lighting state of arbitrary mixed light ratio, the light sending factitious color can be suppressed.

Such as, control part 115 is when being changed to the state of only white light source lighting or being changed to the state of white light source and color light source lighting from the state of only color light source lighting from the state of only color light source lighting, before the control of color light source, first start the control performing white light source.

Such as, control part 115, when being changed to other states of only color light source lighting from the state of only color light source lighting, performs the control of color light source after making white light source lighting, afterwards, performs the control that white light source is turned off the light.

Thus, because first starting the control performing white light source before the control of color light source, therefore, even if change after the mixed light state of color light source, form and aspect also can be suppressed to change in the region of high chroma.Therefore, the light sending factitious color can be suppressed.

Such as, control part 115, when being changed to other states of at least any one lighting in white light source and color light source from the state of white light source and color light source lighting, before the control of white light source, first starts the control performing color light source.

Such as, control part 115, when being changed to the state of only color light source lighting from the state of only white light source lighting, before the control of white light source, first starts the control performing color light source.

Thus, because of the state from white light source lighting, before the control of white light source, first start the control performing color light source, therefore, form and aspect can be suppressed to change in the region of high chroma.Therefore, the light sending factitious color can be suppressed.

Figure 14 is the L be described another example of the control that the control part of embodiment performs ^*a ^*b ^*color space.

L ^*a ^*b ^*the chromaticity coordinate of light-emitting component 133B of light in color space, sending the chromaticity coordinate of the light-emitting component 133R of the light of redness (R), send the chromaticity coordinate of the light-emitting component 133G of the light of green (G) and send blueness (B) is such as shown in Figure 14.

As above about Figure 13 (a) and Figure 13 (b) explanation as described in, be changed to the process of the control of the lighting state of other mixed light ratios in execution from the lighting state of arbitrary mixed light ratio, according to the mixed light ratio of each light-emitting component, send the light of factitious color sometimes.Such as, the situation being changed to the state of the light-emitting component 133B lighting of the light sending blueness (B) from the state of light-emitting component 133R lighting of the light sending redness (R) is as shown in figure 14 described.

When being changed to the state of only light-emitting component 133B lighting from the state of only light-emitting component 133R lighting, if reduce the output of light-emitting component 133R gradually, improve the output of light-emitting component 133B gradually, then shown in the 1st control procedure as shown in figure 14, photochromic at L ^*a ^*b ^*the straight line be linked to be in color space, than the chromaticity coordinate of light-emitting component 133R and the chromaticity coordinate of light-emitting component 133B changes by circumference slightly.Like this, in the 1st control procedure, photochromic meeting through bright-coloured aubergine, thus, factitious impression may be brought to user.

To this, in embodiment, in the process of state being changed to only light-emitting component 133B lighting from the state of only light-emitting component 133R lighting, perform and control as follows: to add green (G) via the mode of the 2nd control procedure, the 2nd control procedure is passed through than the 1st control procedure near L ^*a ^*b ^*the region of the initial point of color space.That is, control part 115 is when being changed to the 2nd lighting state from the 1st lighting state, performs and controls as follows: the photochromic L presented in change procedure ^*a ^*b ^*the colourity of color space is positioned at the region that the straight line be linked to be than the chromaticity coordinate of the 1st lighting state and the chromaticity coordinate of the 2nd lighting state more leans on initial point.

Thus, in the process of lighting state change, because of the photochromic region relatively low through chroma, therefore, the not naturalness of outward appearance can be made to relax.In the example depicted in fig. 14, in the 2nd control procedure, be photochromicly changed to blueness (B) from red (R) through rubescent white and the white of turning blue.Therefore, can suppress to bring factitious impression.

Figure 15 is the flow chart be described the another example of the control that the control part of embodiment performs.

In this example, the situation that have selected " gorgeous " pattern, " comfortable " pattern or " movie theatre " pattern is described.

" gorgeous " button 181 of user's such as operating and remote controlling transmitter 180 and select " gorgeous " pattern (step S101).Or, " comfortable " button 182 of user's such as operating and remote controlling transmitter 180 and select " comfortable " pattern (step S103).Or, " movie theatre " button 183 of user's such as operating and remote controlling transmitter 180 and select " movie theatre " pattern (step S105).

Then, control part 115 judges whether to set timing (timer) function (step S107).Timing function in this example i.e. " timing closing function " of so-called sleep, refers to the function after the stipulated time, light-emitting component 133 being turned off the light.When not setting timing function (step 8107:No), control part 115 continues to judge whether to set timing function (step S107).

On the other hand, pattern that when setting timing function (step S107:Yes), control part 115 performs " sleep is auxiliary ".Control performed under " sleep auxiliary " pattern as such as above about Fig. 9 ~ Figure 12 (b) explanation as described in.Then, control part 115 makes all light-emitting components 133 turn off the light (step S111).Like this, in the example depicted in fig. 15, lighting pattern when have selected beyond " sleep is auxiliary " pattern, when namely have adjusted lighting pattern (the 2nd lighting pattern) of the light output of each illuminant colour in advance, if setting timing function, then control part 115 performs following control: through " sleep is auxiliary " pattern, all light-emitting components 133 are turned off the light.In other words, lighting pattern when have selected beyond " sleep is auxiliary " pattern, when namely have adjusted the lighting pattern of light output of each illuminant colour in advance, if setting timing function, then control part 115 performs following control: from selected lighting mode shifts to " sleep is auxiliary " pattern.This control is from the lighting dim light only made under " gorgeous " pattern, " comfortable " pattern or " movie theatre " pattern and the control of turning off the light is different.

Thus, by making timing function run through not hindering " sleep auxiliary " pattern of falling asleep, thus, even if such as when setting lighting pattern (such as " gorgeous " pattern etc.) with the effect of waking up, also can promote to fall asleep.Therefore, the dysgenic light suppressed sleep can be provided.

" gorgeous " button 181 of user's such as operating and remote controlling transmitter 180 and select " gorgeous " pattern (step S121).Or, " comfortable " button 182 of user's such as operating and remote controlling transmitter 180 and select " comfortable " pattern (step S123).Or, " movie theatre " button 183 of user's such as operating and remote controlling transmitter 180 and select " movie theatre " pattern (step S125).

Like this, control part 115 is set to and can not carries out unit control (step S127).That is, when have selected the lighting pattern of the light output that have adjusted each illuminant colour in advance, control part 115 prohibits following function: adjust the light modulation ratio of each illuminant colour and make the changeable light output of each illuminant colour.Thus, the phenomenon of the effect that cannot obtain specific toning ratio can be suppressed.In other words, the set information of each lighting pattern of the light output that have adjusted each illuminant colour in advance can be kept.

In addition, when have selected " sleep is auxiliary " pattern, can the light bulb color (L) of lighting under " sleep auxiliary " pattern, red (R) and green (G) scope in, adjust the light modulation ratio of each illuminant colour and make the changeable light output of each illuminant colour.That is, under " sleep is auxiliary " pattern, also light modulation and toning can be carried out in the scope of light bulb color (L), red (R) and green (G).

Then, control part 115 judges whether to be set as " full light " pattern (step S129).So-called " full light " pattern refers to, the light output making all light-emitting components 133 of the light bulb color in light source portion 130 (L) and color of sunshine (D) is maximum and by the pattern of illuminant colour colour mixture.In " full light " pattern, the high and light of the daylight colour system that colour rendering is excellent of the repeatability embodying color.When not being set as " full light " pattern (step S129:No), control part 115 continues to judge whether to be set as " full light " pattern (step S129).

On the other hand, when such as user is set as " full light " pattern by " full light " button 189 (with reference to Fig. 8 (a) and Fig. 8 (b)) of operating and remote controlling transmitter 180 (step S129:Yes), control part 115 is removed and can not be carried out the state of unit control, and is set to and can carries out unit control (step S131).In addition, control part 115 not only can remove the state can not carrying out unit control when being set as " full light " pattern, and also can be removed by during releasing the state can not carrying out unit control in selected lighting pattern (" gorgeous " pattern, " comfortable " pattern or " movie theatre " pattern).Thus, user can " R " button 185 of such as operating and remote controlling transmitter 180, " G " button 186 and " B " button 187, and adjusts the light modulation ratio of each illuminant colour thus make the changeable light output of each illuminant colour.

In addition, be not limited to this example, when have selected " gorgeous " pattern, " comfortable " pattern or " movie theatre " pattern, the unit control of redness (R), green (G) and blue (B) also can be carried out in the scope of each lighting pattern.Thus, in the scope of each lighting pattern, inching can be carried out to red (R), green (G) and blue (B).

Or, when have selected " gorgeous " pattern, " comfortable " pattern or " movie theatre " pattern, also unit control can be carried out for untapped illuminant colour under each lighting pattern.Thus, inching can be carried out to untapped illuminant colour under each lighting pattern.

If " after 30 minutes close " button of user's such as operating and remote controlling transmitter 180 188 (with reference to Fig. 8 (a) and Fig. 8 (b)) and select timing function (step S141), then control part 115 performs following control: first make the main light source in main light source and secondary 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 above about Figure 15 explanation as described in.

Such as, when sending the mixed light of light of the light of light bulb color (L), the light of redness (R) and green (G), if " after 30 minutes close " button 188 of user's such as operating and remote controlling transmitter 180 and select timing function, then control part 115 first make the light-emitting component 133L of the light sending light bulb color (L), send the light-emitting component 133R of the light of redness (R) and send green (G) light light-emitting component 133G in light-emitting component 133L turn off the light.Then, control part 115 makes light-emitting component 133R and light-emitting component 133G turn off the light.

Thus, generally speaking, the illumination of main light source, higher than the illumination of secondary light source, therefore, by making the illumination of main light source first decline, thus the secondary light source ignition that illumination can be made before light-off relatively low, and utilizes relatively low illumination to carry out lights-out operations.Therefore, the dysgenic light suppressed sleep can be provided.

If " after 30 minutes close " button 188 of user's such as operating and remote controlling transmitter 180 and select timing function (step S151), then control part 115 performs the control (step S153) that the secondary light source in main light source and secondary light source is first 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.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.

Such as, when sending the mixed light of light of the light of light bulb color (L), the light of redness (R) and green (G), if " after 30 minutes close " button 188 of user's such as operating and remote controlling transmitter 180 and select timing function, then control part 115 make the light-emitting component 133L of the light sending light bulb color (L), send the light-emitting component 133R of the light of redness (R) and send green (G) light light-emitting component 133G in light-emitting component 133R 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 light and the correlated colour temperature of the mixed light of the light of green (G) of red (R) brings incongruity before light-off, by making light-emitting component 133R and light-emitting component 133G first turn off the light, the incongruity before light-off can be eliminated.Now, the light of light bulb color (L) can be provided before light-off.

In this example, situation light-emitting component 133L, the light-emitting component 133R sending the light of redness (R) of light and the light-emitting component 133G of light that sends green (G) that send light bulb color (L) being in light-off state is described.

The circuit component 116 being located at the inside chassis of power supply unit 110 comprises not shown sensor (sensor).As sensor, the force-feeling sensor etc. of the existence such as sensing people can be enumerated.As force-feeling sensor, the sensor such as using ultrared sensor or use hyperacoustic sensor or use microwave can be enumerated.In addition, sensor also can be installed in apparatus body 120.

According to the opinion of this novel creator, color temperature or relatively low photochromic of correlated colour temperature not easily hinder sleepiness.Therefore, before bedtime or in the relatively short illumination of the time at night, color temperature or correlated colour temperature relatively low photochromic preferably.But, in order to realize color temperature or relatively low photochromic of correlated colour temperature, color temperature or the relatively low light-emitting component of correlated colour temperature must be used.

To this, in the example shown in Figure 19, when light-emitting component 133L, the light-emitting component 133R sending the light of redness (R) of light and the light-emitting component 133G of light that sends green (G) that send light bulb color (L) are in light-off state (step S161), control part 115 judges whether force-feeling sensor senses people (step S163).When force-feeling sensor does not sense people (step S163:No), control part 115 continues to judge whether force-feeling sensor senses people (step S163).

On the other hand, when force-feeling sensor senses people (step S163:Yes), control part 115 makes the light-emitting component 133L of the light sending light bulb color (L), send the light-emitting component 133R of the light of redness (R) and send the light-emitting component 133G lighting of light of green (G), and becomes the correlated colour temperature lighting state (step S165) lower than the correlated colour temperature under the state of only light-emitting component 133L lighting.Such as, pattern that when force-feeling sensor senses people (step S163:Yes), control part 115 performs " sleep is auxiliary ".

Thus, before bedtime or the relatively short operation of the time at night time, the ligthing paraphernalia 100 of embodiment senses people and lighting automatically.The photochromic correlated colour temperature of lighting is lower than the correlated colour temperature of light-emitting component 133L of light sending light bulb color (L).Therefore, before bedtime or the relatively short operation of the time at night time, can realize not easily hindering the photochromic of sleepiness.Such as, when user is when going to toilet (toilet) etc. night, can not impels and wake user up, can suppress to hinder the phenomenon of again going to bed.

Then, the illuminator of the ligthing paraphernalia 100 and sense mechanism that comprise embodiment is described.

Illuminator comprises above about the ligthing paraphernalia 100 described in Fig. 1 (a) ~ Figure 19 and sense mechanism.As sense mechanism, such as force-feeling sensor, organism sensor, imageing sensor or load cell etc. can be enumerated.As force-feeling sensor, can enumerate and such as use ultrared sensor, use the sensor of hyperacoustic sensor or use microwave.As organism sensor, can enumerate and pulse wave, electrocardio, body temperature, body to be moved or the Biont information such as blood pressure carries out the sensor that measures.As imageing sensor, the imageing sensor such as with camera (camera) etc. can be enumerated, and to the sensor that the activity of people or the activity etc. of eyes sense.

In the illuminator of embodiment, by sensor to occupant in the bedroom in go to bed before action sense, according to the sensing result of sensor, after the stipulated time, automatically make ligthing paraphernalia 100 turn off the light.Such as, if sensor senses occupant's action before bedtime, then illuminator starts ligthing paraphernalia 100 is turned off the light after 5 minutes, and makes ligthing paraphernalia 100 dim light after time of such as about 10 minutes under the degree can not noted occupant and automatically turn off the light.As " action before going to bed ", can enumerate such as, occupant enters the action in bedroom, occupant sits action in bed, prepare the action of sleep, feel the activity of the eyes of sleepiness, wear the action of nightwear or action etc. after a bath.

Thus, by being sensed the action before the going to bed of occupant by sensor, then occupant is without the need to specifically operating, and ligthing paraphernalia 100 just can be made automatically to turn off the light after the stipulated time.

Other illuminators of embodiment comprise above about the multiple ligthing paraphernalias 100 described in Fig. 1 (a) ~ Figure 19.Unit control address (address) is provided with separately for multiple ligthing paraphernalia 100.Control part 115 with the time difference to the light modulation of multiple ligthing paraphernalia 100 and toning at least any one controls.

Such as, multiple ligthing paraphernalia 100 is configured in the scope from ceiling to floor.Such as, when multiple ligthing paraphernalia 100 performs " sleep is auxiliary " pattern, control part 115 performs following control: from ceiling to floor, with 20 minutes, 21 minutes, 22 minutes, the light-emitting component 133L of the light sending light bulb color (L) is turned off the light.Then, control part 115 performs following control: with 28 minutes, 29 minutes, 30 minutes, ligthing paraphernalia 100 is turned off the light completely.That is, control part 115 sequentially makes the ligthing paraphernalia 100 being configured at ceiling turn off the light to the ligthing paraphernalia 100 being arranged at floor.Thus, the time difference light modulation of turning off the light in the mode of sunset can be realized.

Or such as, control part 115 performs following control: the illuminant colour colour mixture making color of sunshine (D) and blue (B).Such as, control part 115 makes the light-emitting component 133L lighting of the light sending light bulb color (L) from the light-off state of ligthing paraphernalia 100, afterwards, make the light-emitting component 133D of the light sending color of sunshine (D) with send blueness (B) light light-emitting component 133B lighting and perform light modulation and in mixing colours at least any one.Thus, can impel and wake user up.

Or such as, multiple ligthing paraphernalia 100 is configured at the scope from ceiling to floor.Such as, when ligthing paraphernalia 100 is in light-off state, control part 115 performs following control: from being arranged at the ligthing paraphernalia 100 on floor to the ligthing paraphernalia 100 being configured at ceiling, in the mode of 0 minute, 1 minute, 2 minutes, being staggered the time and starting lighting.Then, control part 115 makes light-emitting component 133L lighting, and from floor to ceiling, performed after 8 minutes, 9 minutes, 10 minutes in light modulation and toning at least any one.Then, control part 115 makes light-emitting component 133D and light-emitting component 133B lighting, and from floor to ceiling, performed after 28 minutes, 29 minutes, 30 minutes from light modulation and toning at least any one.Thus, can realize with the time difference light modulation of the mode lighting of sunrise.
