Ambient lighting device 10 is mainly to irradiate working lining all lighting devices, for example, be lighting device on ceiling etc.Task lighting device 20, centered by operation object, offers desirable illumination the lighting device of operating area, for example, be that table is upper with lighting device etc.Ambient lighting device 10 and task lighting device 20 can be set to number arbitrarily.

The light source utilization of ambient lighting device 10 and task lighting device 20 can be used LED.A feature as LED is that easily the color temperature to light source (photochromic) is adjusted.In the situation that ambient lighting device 10 and task lighting device 20 adopt LED, be not only the output of light, even if color temperature also can be controlled with ambient lighting device 10 and 20 interlocks of task lighting device.

Control part 30 is photochromic to ambient lighting device 10 and task lighting device 20, and color temperature is adjusted.Form according to this, can dynamically control lighting space, the variation of the color temperature by lighting space, thus various functions can be provided.

Particularly, control part 30, according to the illumination condition being detected by illumination condition detecting sensor 40, is controlled the color temperature of ambient lighting device 10 and task lighting device 20.Now, control part 30 utilizes the communication systems such as PLC (Power Line Communications: power line communication) communication or radio communication, and ambient lighting device 10 and task lighting device 20 are controlled.And control part 30, for ambient lighting device 10 and task lighting device 20, except color temperature, is also controlled illumination, luminous intensity distribution.

Illumination condition detecting sensor 40 is for example the chroma meter for detection of color temperature, and the lighting space of ambient lighting device 10 and task lighting device 20 is detected, and color temperature is detected.Form according to this, by illumination condition detecting sensor 40 is used as to color temperature sensor, thereby can realize more easy system.

And illumination condition detecting sensor 40, by communication units such as plc communication or other wireless communication units, sends to control part 30 by the illumination condition detecting.And illumination condition detecting sensor 40, except color temperature, also detects illumination, luminous intensity distribution.

Illumination condition detecting sensor 40 possesses: the illumination condition detecting sensor 40a that the illumination condition of operating area is detected; And to the illumination condition detecting sensor 40b that comprises that the illumination condition in space of operating area and neighboring area detects.Illumination condition detecting sensor 40b is by being arranged near of ambient lighting device 10, thereby mainly the illumination condition of ambient lighting device 10 detected.And illumination condition detecting sensor 40a is by being arranged near of task lighting device 20, thereby mainly the illumination condition of task lighting device 20 is detected.By possessing the illumination condition detecting sensor 40a of task lighting device 20 use and the illumination condition detecting sensor 40b of ambient lighting device 10 use, thus correctly environment-identification lighting device 10 and the mutual color temperature of task lighting device 20 of illuminator 1.

And, in the illumination condition detecting at illumination condition detecting sensor 40a and 40b, also can comprise respectively the impact of the illumination producing because of ambient lighting device 10 and task lighting device 20.And, in the illumination condition of illumination condition detecting sensor 40a and 40b detection, also can comprise the impact that is irradiated to indoor extraneous light from window.

As shown in figure 12, illuminator 1001 comprises: ambient lighting device 1010, task lighting device 1020, control part 1030 and illumination condition detecting sensor 1040.According to this formation, in illuminator 1001, by ambient lighting device 1010 and the color temperature of task lighting device 1020 are adjusted, thereby can reduce the obvious edge sense causing because of the large difference of ambient lighting device 1010 and the photochromic appearance of task lighting device 1020, and can reduce the uncomfortable sensation of bringing because of user's inharmonious sense.Therefore, user's concentrated force can be improved, thereby mental labour productivity ratio can be improved.And ambient lighting device 1010, task lighting device 1020, illumination condition detecting sensor 1040 and control part 1030 also can have respectively communication unit.Control part 1030, according to the information of the illumination condition being detected by illumination condition detecting sensor 1040 receiving via communication unit, is controlled the illumination of ambient lighting device 1010 and task lighting device 1020.

Ambient lighting device 1010 is mainly to irradiate working lining all lighting devices, for example, be lighting device on ceiling etc.Ambient lighting device 1010 for example can use LED.

Task lighting device 1020 centered by operation object, desirable illumination is offered to the lighting device of operating area, be for example that table is upper with lighting device etc.

The illumination conditions such as photochromic, the color temperature of control part 1030 to ambient lighting device 1010 and task lighting device 1020, luminous intensity distribution are adjusted.The illumination condition that control part 1030 detects according to illumination condition detecting sensor 40, photochromic, color temperature, luminous intensity distribution to ambient lighting device 1010 and task lighting device 1020 are controlled.Now, control part 1030 utilizes the communication systems such as PLC (Power LineCommunications: power line communication) communication or radio communication, and ambient lighting device 1010 and task lighting device 1020 are controlled.

Illumination condition detecting sensor 1040 is for example chroma meter, and the lighting space of ambient lighting device 1010 and task lighting device 1020 is detected, for example, the illumination condition such as illumination, color temperature is detected.Illumination condition detecting sensor 1040 possesses: the illumination condition detecting sensor 1040b of the illumination condition detecting sensor 1040a of task lighting device 1020 use and ambient lighting device 1010 use.Illumination condition detecting sensor 1040b is by being arranged near of ambient lighting device 1010, thereby mainly the illumination condition of ambient lighting device 1010 detected.And, be arranged near of task lighting device 1020 by illumination condition detecting sensor 1040a, thereby mainly the illumination condition of task lighting device 1020 detected.By possessing the illumination condition detecting sensor 1040a of task lighting device 1020 use and the illumination condition detecting sensor 1040b of ambient lighting device 1010 use, thus the correctly both sides' of environment-identification lighting device 1010 and task lighting device 1020 color temperature of illuminator 1001.

And, in illumination condition detecting sensor 1040a and 1040b, also can contain respectively the impact from the illumination of ambient lighting device 1010 and task lighting device 1020.

Figure 13 shows the illuminator 1001 that can control ambient lighting device 1010 and task lighting device 1020.

Ambient lighting device 1010, task lighting device 1020, the residing state of illumination condition detecting sensor 1040 are to utilize the communication systems such as above-described control part 1030 and plc communication or radio communication to carry out two-way communication.

For example, even in the color temperature that is arranged on the task lighting device 1020 of table on 1050 situation different from the color temperature of ambient lighting device 1010 that is arranged on ceiling, in the time that illumination condition detecting sensor 1040 (illumination condition detecting sensor 1040a) detects the color temperature of task lighting device 1020, the color temperature that control part 1030 detects according to illumination condition detecting sensor 1040a, controls the color temperature of ambient lighting device 1010.Particularly, control part 1030 is photochromic according to operating area, according to the variation of the illumination condition of task lighting device 1020, the color temperature of exporting from ambient lighting device 1010 is controlled, so that the difference of the color temperature of neighboring area and the color temperature of operating area diminishes,, the difference of the color temperature of ambient lighting device 1010 and the color temperature of task lighting device 1020 is diminished.Accordingly, can control the photochromic of neighboring area according to the photochromic variation of operating area.

Now, control part 1030 is for example adjusted the color temperature of ambient lighting device 1010, so that the poor color temperature that becomes the equal extent that is less than 2000K of the color temperature of the color temperature of the color temperature of ambient lighting device 1010 and task lighting device 1020.About the adjustment of the color temperature of ambient lighting device 1010, can be that ambient lighting device 1010 is adjusted automatically, also can be to select adjustment button (not shown) to operate by user to the color temperature adjustment dial or the color temperature that are arranged on ambient lighting device 1010, manually adjust.Accordingly, can be according to the photochromic variation of neighboring area (ambient lighting device 1010), make the color temperature of operating area (task lighting device 1020) become the color temperature being almost equal to, thereby realize the space that there is no inharmonious sense.

And, even if task lighting device 1020 has different color temperatures from ambient lighting device 1010, in the time that illumination condition detecting sensor 1040 (illumination condition detecting sensor 1040b) detects the color temperature of ambient lighting device 1010, the color temperature that control part 1030 also can detect according to illumination condition detecting sensor 1040a, controls the color temperature of ambient lighting device 1010.Particularly, control part 1030 is according to the variation of the illumination condition of the photochromic ambient lighting device 1020 as neighboring area, control the color temperature of exporting from task lighting device 1020, so that the difference of the color temperature of neighboring area and the color temperature of operating area diminishes,, the difference of the color temperature of ambient lighting device 1010 and the color temperature of task lighting device 1020 is diminished.Accordingly, can, according to the photochromic variation of neighboring area, the photochromic of operating area be controlled.

Now, control part 1030 is for example adjusted the color temperature of task lighting device 1020, so that the poor color temperature that becomes the equal extent that is less than 2000K of the color temperature of the color temperature of the color temperature of ambient lighting device 1010 and task lighting device 1020.About the adjustment of the color temperature of ambient lighting device 1010, can be that ambient lighting device 1010 is adjusted automatically, also can be to select adjustment button (not shown) to operate by user to the color temperature adjustment dial or the color temperature that are arranged on ambient lighting device 1010, manually adjust.Accordingly, can be according to the photochromic variation of operating area (task lighting device 1020), make the color temperature of neighboring area (ambient lighting device 1010) become the almost color temperature of equal extent, thereby can realize the space that there is no inharmonious sense.

And, change, the color temperature of task lighting device 1020 and ambient lighting device 1010 can be controlled to the color temperature that is less than 2000K to photochromic having carried out of task lighting device 1020 and ambient lighting device 1010 too in the case of user.

And illumination condition detecting sensor 1040 is not limited near that is arranged on ambient lighting device 1010 or task lighting device 1020, for example, also can be arranged on wall.Illumination condition detecting sensor 1040 is by being arranged on wall, thereby also can testing environment lighting device 1010 and task lighting device 1020 these both sides' illumination condition.And illumination condition detecting sensor 1040, except the illumination condition of ambient lighting device 1010 and task lighting device 1020, can also detect the illumination condition of extraneous light.

And, illumination condition detecting sensor 1040 is limit by an institute not, also can arrange multiple, can be separately positioned on as described above ambient lighting device 1010 and task lighting device 1020, for example, also can in multiple ambient lighting devices 1010 or task lighting device 1020, jointly use.

And, even in the case of there is no to detect the illumination condition detecting sensor 1040 of lighting space, also can realize by identical control program.Its example is illustrated by Figure 14.Figure 14 illustrates that of the related illuminator of execution mode controls the sequential chart of example.

As shown in figure 14, also can prepare in advance the control program for control part 1030 is controlled, thereby according to the variation of the color temperature of the illumination of ambient lighting device 1010, the color temperature of the illumination of task lighting device 1020 be changed.Because control part 1030 has control program, the therefore correctly mutual color temperature of environment-identification lighting device 1010 and task lighting device 1020 of control part 1030.

(a) of Figure 14 shows an example of the timing variations of the color temperature of the illumination of ambient lighting device 1010.The illumination of ambient lighting device 1010 for example can be prepared the control program changing according to the rule of life of nature and human body.For example, the illumination of ambient lighting device 1010 is set as, during time t1 to t2, is being 5000K, during time t2 to t3, is being 3000K, during time t3 to t4, is being 6700K, during time t4 to t5, is being 2500K.

(b) of Figure 14 shows an example of the timing variations of the color temperature of the illumination of task lighting device 1020.Prepare control program, so that the illumination change of task lighting device 1020 is the color temperature identical with the color temperature of ambient lighting device 1010.Accordingly, for task lighting device 1020, also can make it same with ambient lighting device 1010, rule of life according to human body changes, under neighboring area and operating area are maintained in based on the same photochromic state that is easy to intensity, level of comfort, natural degree, control.

Now, control part 1030 as shown in figure 13, also can possess timer 1032, thereby can, according to the above-mentioned time interval, at least one party of task lighting device 1020 and ambient lighting device 1010 be controlled.Accordingly, can be according to time interval control task lighting device 1020 and ambient lighting device 1010 simply.And, even in lighting space is not fixing environment, also can provide comfortable lighting space always.

And, although ambient lighting device 1010 is controlled to identical with the color temperature of task lighting device 1020 in Figure 14, but also nonessential is identical, also can for example be less than under the state of 2000K in ambient lighting device 1010 and the difference of the color temperature of task lighting device 1020, color temperature is suitably changed.

In sum, the illuminator 1001 related according to present embodiment, can provide the lighting space that is suitable for intensive work.

As shown in Figure 19 (a), illuminator 2200 possesses ambient lighting device 2101 and is arranged on the task lighting device 2202 on Working table 2105.And illuminator 2200, as Figure 19 (a) and (b), possesses illumination condition detecting sensor 2203 above task lighting device 2202.And, about the formation of the illuminating part of task lighting device 2202, the formation of utilizing the task lighting device 2102 shown in Figure 16 is illustrated later.

The illumination zone of task lighting device 2202, operating area, as shown in Figure 19 (b), is a surperficial part for Working table 2105.The illumination zone of task lighting device 2202 can change.For example, in the case of the irradiation (narrow angle luminous intensity distribution) of close limit, irradiation area is to be the scope that is less than 500mm from irradiating center to the length of long axis direction.And in the case of the irradiation (wide-angle light-distribution) of wide scope, irradiation area is to be the scope below the above 1000mm of 500mm from irradiating center to the length of long axis direction.At this, " length of long axis direction " refers to, the diameter in just round situation, or the longest diameter in oval situation.About the range of exposures of task lighting device 2202, by below illuminating part (light-emitting area) optics (cartridge) 2214 is set, can narrow.

Figure 20 shows the Luminance Distribution the having or not of optics (cartridge) 2214 of the AA ' face in the range of exposures of task lighting device 2202.In Figure 20, transverse axis represents the distance apart from center, and the longitudinal axis represents brightness.As shown in figure 20, under the state that has optics (cartridge) 2214 (having cartridge), can see that brightness changes part greatly in measurement range (300mm to 300mm).Therefore,, due to the difference of irradiation brightness, observer can confirm the edge sense of range of exposures.

At this, in the task lighting device 2202 with above this formation, invention personnel of the present utility model notice the edge of the lip-deep range of exposures of Working table 2105 as the means of illumination that improves concentrated force.

First, having or not of the optics (cartridge) 2214 of invention personnel of the present utility model by task lighting device 2202, under the illumination condition and the surface identification that is almost radiated at Working table 2105 with the illumination of the homogeneous state less than the edge of irradiation pattern of lip-deep range of exposures that can recognize Working table 2105, implement subjective assessment, thereby it is high to find to recognize concentrated force, comfortableness and naturality in the lighting space at edge.Figure 21 A to Figure 21 C shows experimental result.The implementation method of subjective assessment is, adopt task environment means of illumination, make shadow surface center illumination be fixed on 750lx, under 19 following conditions, for the reading degree that is easy to of word, the evaluation of table surface and the evaluation of lighting space, to " be easy to intensity ", " level of comfort ", " natural degree " is as assessment item, carry out respectively the evaluation in 7 stages, described 19 conditions comprise: 2 kinds of the irradiation pattern of task illumination, 3 kinds of environment and task level of illumination, 4 kinds that environment is photochromic, 2 kinds that task is photochromic.

And the scope of experiment is not the combination of having enlisted the services of all kinds, but will pay close attention to main points as scope.As with this rim condition of range of exposures of paying close attention to main points being, ambient lighting is made as to 300lx:450lx with respect to the shadow surface center illumination of task illumination, and make that ambient lighting throws light on task photochromic identical, be 5000K.Light not being exported to the Luminance Distribution under the state of adjusting although show in Figure 20, in when experiment, is that illumination is adjusted into equal rank and implemented afterwards by center brightness.Carry out the irradiation pattern of two kinds of experiment using following irradiation pattern (i) and irradiation pattern (ii) as condition, irradiation pattern (i) refers to, can identify the edge of range of exposures, the pattern that the diameter that comprises A3 paper size (being of a size of 297 × 420mm) is 500mm, irradiation pattern (ii) refer on the table surface of 600 × 1200mm can not explicit recognition to the pattern of range of exposures.And subject amounts to 30, be respectively 10 of 10,50 to 60 years old age level of 10,40 years old age level of 20 to 30 years old age level.

And, as the order of experiment be, after first adapting to the Essential Environment illumination of 5 minutes, change lighting condition and adapt to again 1 minute, make afterwards subject carry out the visual task of 1 minute, carry out subjective assessment.For the second time in the situation of later subjective assessment, after changing lighting condition and adapting to 1 minute, the visual task that subject is carried out 1 minute, and subjective assessment repeatedly.

Figure 21 A to Figure 21 C shows the experimental result of subjective assessment.In Figure 21 A to Figure 21 C, " operating area " represents to have the irradiation pattern (i) in the situation of above-mentioned cartridge, and " table surface is all " represents not have the irradiation pattern (ii) in the situation of above-mentioned cartridge.And show the mean value using irradiation pattern (i) and " being easy to intensity " (ii), " level of comfort ", " natural degree " as the evaluation result in 7 stages of assessment item, additional line represents standard error.

Known according to above-mentioned experimental result, the irradiation pattern that can recognize the edge of shadow surface is easy to concentrate, comfortable and natural.The width of the desk that generally speaking, office etc. is used is 1100mm.And in the specification of the desk lamp (study, reading) of the fluorescent lamp of JISC8112, the standard of recording as the confirmation position of light-proofness is, apart from the 600mm at shadow surface center and be 400mm apart from the height of the sight line of table surface.So using viewpoint as described standard in the situation that, generally speaking, visual angle when people concentrates is about 46 degree, minimal visual angle that can recognition object is about 60 degree.

The visual angle when length of the long axis direction of the operating area of this irradiation pattern (i) is (diameter) 500mm is approximately 38 degree, in angular field of view that can be concentrated people.And the in the situation that of being 60 degree at visual angle, the diameter that irradiates little pattern is 840mm, owing to being almost the size of newspaper, therefore preferred optically focused scope is the size from A3 size to newspaper size, that is: from diameter pattern 420 till the size of 840mm.And, all owing to also wishing to be irradiated to table surface, therefore preferably 1000mm of the upper limit of optically focused scope.

As can be seen from the above, preferably the length of above-mentioned long axis direction is less than to the narrow angle of being made as of 500mm luminous intensity distribution, by the wide-angle light-distribution that is made as below above 500mm 1000mm, carry out the distribution controls of illuminator 2200 to be adjusted into narrow angle luminous intensity distribution or wide-angle light-distribution.Form according to this, can realize lighting space that user is easy to concentrate, comfortable and natural.

At this, the adjustment work of the luminous intensity distribution to illuminator 2200 describes.

Figure 22 is the flow chart that the adjustment work of the luminous intensity distribution of illuminator 2200 is shown.Because user can feel that the color temperature of inharmonious sense is poor for more than 2000K, therefore preferably set for, in the time of the near 2000K of color temperature differential, for example poor for 2000K when above, preferably becoming 1700K when above in color temperature, the luminous intensity distribution of operating area is changed.The work of the luminous intensity distribution adjustment of carrying out when the temperature difference of below checking colors becomes 1700K describes.

As shown in figure 22, first by being configured in the illumination condition detecting sensor 2203 on task lighting device 2202, detecting the photochromic of the light that irradiates from ambient lighting device 2101, i.e. testing environment color temperature A (step S20).And, the light irradiating from task lighting device 2202 photochromic, task color temperature T is also detected.

Now, difference at task color temperature T and ambient color temperature A is less than ("No" of step S22) 1700K, and illumination condition detecting sensor 2203 detects photochromic (the step S20) of the light irradiating from ambient lighting device 2101 again.And, in the case of the difference of task color temperature T and ambient color temperature A be more than 1700K ("Yes" of step S22), control part 2204 make task lighting device 2202 luminous intensity distribution increase control (step S24).Accordingly, in illuminator 2200, the large aberration of the marginal portion of causing because of the large photochromic difference between ambient lighting device 2101 and task lighting device 2202 can be reduced, thereby the uncomfortable sensation producing because of user's inharmonious sense can be reduced.Therefore, user's concentrated force can be improved, thereby mental labour productivity ratio can be heightened.

And, also can carry out the work that the color temperature to operating area shown in execution mode 5 is adjusted with the adjustment work of above-mentioned luminous intensity distribution with matching.Accordingly, can reduce the large aberration of the marginal portion of causing because of the large photochromic difference between ambient lighting device 2101 and task lighting device 2202, therefore can reduce the uncomfortable sensation producing because of user's inharmonious sense.

Then, the method for the expansion luminous intensity distribution in task lighting device 2202 is described.The method of the luminous intensity distribution of expansion task lighting device 2202 has following 3 kinds, that is: the method for lighting a lamp, (2) of (1) control solid-state light emitting element (LED element) utilize method, (3) of optics (cartridge) 2214 to utilize the movement of solid-state light emitting element and the method for specular reflective material.Below above-mentioned method is described respectively.

First, the method for lighting a lamp of the control solid-state light emitting element 2211 to (1) describes.Figure 23 is the figure that an example of the formation of the illuminating part of the related task lighting device 2202a of this method is shown, (a) is bottom view, is (b) sectional view at BB ' the line place of (a).

As shown in Figure 23 (a), the illuminating part of task lighting device 2202a possesses as solid-state light emitting element 2211: be configured near the LED element 2211a of central authorities and the LED element 2211b being configured to surround the mode of LED element 2211a.

At this, in the case of the luminous intensity distribution of task lighting device 2202a is expanded, the control that control part 2204 is all lit a lamp LED element 2211a and LED element 2211b both sides.In this case, control part 2204 is in order to emphasize the marginal portion of task illumination, makes to be configured near the control of the LED element 2211b dim light central authorities of illuminating part.

And in the case of making the luminous intensity distribution of task lighting device 2202a narrows, the control that control part 2204 carries out is, LED element 2211b is turned off the light, and LED element 2211a is lit a lamp.

Accordingly, can carry out distribution controls at task lighting device 2202a.

Then, the method for utilizing optics (cartridge) 2214 of (2) is described.

On the solid luminescence face (illuminating part) of the related task lighting device 2202b of present embodiment, possesses optics (cartridge) 2214.The interior outside of this optics (cartridge) 2214 is coated in white taking aluminium as stock, and is constituted as inner face and can carries out scattered reflection to light.In the past, because the bulb-shaped lamp as light source and fluorescent lamp have luminous intensity distribution angles more than 180 degree, therefore, about with the configuration relation of optics (cartridge) 2214, need to reduce the light returning to light source, like this, the method mostly adopting is that light source is configured in to parabolical focus, and using inner face as specular reflective material.In addition, adopted the planar light source of solid-state light emitting element 2211 to have lambert's type luminous intensity distribution, luminous intensity distribution angle is below 180 degree.Therefore, with the configuration relation of optics (cartridge) 2214 in, can be in light-emitting area the end face of mounting optical component (cartridge) 2214.Therefore, among light irradiation, return to the light of light-emitting area and reduce, and by inner face is used as to scattered reflection material, thereby can realize the irradiation pattern that the uniformity is high by multipath reflection.And, because inner face is scattered reflection material, therefore compared with specular reflective material, can suppress the dazzling light (dazzle) causing because of optics inner face.In the situation that paying attention to efficiency, optics (cartridge) 2214 preferably adopts specular reflective material, pass through specular reflective material, thereby the luminance difference of light source is reflected to shadow surface, on shadow surface, can confirm luminance difference like this, and then, the dazzle of the inner face by optics (cartridge) 2214, and bring large obstacle to visual experience.

And, in above-mentioned optics (cartridge) 2214, by optics (cartridge) 2214 is arranged to taper, as shown in figure 16, make the diameter (w1) of light-emitting area one side larger (for example than the diameter of shadow surface one side (w2), be that w1 is that 67mm, w2 are 72mm in the present embodiment), thus the light that turns back to light-emitting area can be reduced.Accordingly, can improve the ejaculation efficiency from task lighting device 2202.

Figure 24 A to Figure 24 C shows the example of the formation of the related task lighting device of this method.

In the task lighting device 2202b shown in Figure 24 A, the outside of optics (cartridge) 2214 has helicitic texture 2214a, is screwed up and is configured mutually by the helicitic texture 2214b of inner face with the lower side frame body 2118 that is arranged on illuminating part.Therefore, user passes through rotary optical parts (cartridge) 2214, thereby optics (cartridge) 2214 can be stretched out in side frame body 2118 from illuminating part or retract.Accordingly, can adjust the luminous intensity distribution of task lighting device 2202b.

Particularly, by optics (cartridge) 2214 side frame body 2118 from illuminating part is stretched out, thereby, increase as the solid-state light emitting element 2211 of light source and the distance of the lower end of optics (cartridge) 2214, like this, blocked by optics (cartridge) 2214 near the light spreading laterally the central authorities of illuminating part, therefore, can make the luminous intensity distribution of task lighting device 2202b narrow.

And, by optics (cartridge) 2214 being retracted into the lower side frame body 2118 of illuminating part, thereby, solid-state light emitting element 2211 as light source diminishes with the distance of the downside of optics (cartridge) 2214, like this, can do not blocked by optics (cartridge) 2214 near the light spreading laterally the central authorities of illuminating part, therefore, can expand the luminous intensity distribution of task lighting device 2202b.

Accordingly, at the edge of wanting to emphasize task illumination,, in the situation on the border of ambient lighting and task illumination, optics (cartridge) 2214 is stretched out from lower side frame body 2118, in the case of want to make the edge of task illumination soft, by making optics (cartridge) 2214 be retracted into lower side frame body 2118, thereby can realize desirable lighting space.

In addition, stretching out or retract for optics (cartridge) 2214 side frame body 2118 from illuminating part, can be by manually the carrying out of user, and also can automatically be carried out by motor.The formation of Figure 24 B and the shown task lighting device of Figure 24 C 2202c is, optics (cartridge) 2214 is by the motor situation that side frame body 2118 stretches out from illuminating part and be retracted into the situation of lower side frame body 2118.

As shown in Figure 24 B and Figure 24 C, in task lighting device 2202c, be configured motor 2215 at illuminating part.Motor 2215 is controlled by control part 2204.In the case of wanting to make the luminous intensity distribution of task illumination narrows, control part 2204 is controlled motor 2215, as shown in Figure 24 B, so that optics (cartridge) 2214 side frame body 2118 from illuminating part stretches out.In the case of wanting to make the luminous intensity distribution expansion of task illumination, as shown in Figure 24 C, control part 2204 is controlled motor 2215, so that optics (cartridge) 2214 is retracted into the lower side frame body 2118 of illuminating part.

Accordingly, can, according to the color temperature of the ambient lighting being detected by illumination condition detecting sensor 2203 and task illumination, carry out the luminous intensity distribution of control task illumination.Therefore, can reduce the excessively strong edge sense causing because of the large photochromic difference between ambient lighting device 2010 and task lighting device 2020, thereby can reduce the uncomfortable sensation of bringing because of user's inharmonious sense.

Therefore, user's concentrated force can be improved, thereby mental labour productivity ratio can be improved.

Then, the movement that utilizes solid-state light emitting element to (3) and the method for specular reflective material describe.

Figure 25 A and Figure 25 B illustrate the sectional view that carries out the formation of the task lighting device of distribution controls by the movement of solid-state light emitting element.

As shown in Figure 25 A and Figure 25 B, in the inside of the lower side frame body 2118 of task lighting device 2202d, can surround the mode of the position that has configured solid-state light emitting element 2211, dispose the reflecting material of the tubular with taper, and, preferably specular reflective material 2216.

And, same with above-mentioned task lighting device 2202c, as shown in Figure 25 A and Figure 25 B, at task lighting device 2202d, configure motor 2215 at illuminating part.

Motor 2215 is controlled by control part 2204.

In the case of wanting to make the luminous intensity distribution of task illumination narrows, as shown in Figure 25 A, control part 2204 is controlled, so that solid-state light emitting element 2211 moves to the inside of the upper side frame body 2119 of the lower side frame body 2118 of illuminating part.Accordingly, owing to can making to increase as the solid-state light emitting element 2211 of light source and the distance of the lower end of the lower side frame body 2118 of illuminating part, therefore near the central authorities of illuminating part laterally diffusion light by side frame body 2118 block, thereby can make the luminous intensity distribution of task lighting device 2202d narrow.

And, want in the situation of luminous intensity distribution of expansion task illumination, as shown in Figure 25 B, control part 2204 is controlled, so that solid-state light emitting element 2211 moves near the opening of lower side frame body 2118 of illuminating part.Accordingly, because the solid-state light emitting element 2211 as light source and the distance of the lower end of the lower side frame body 2118 of illuminating part diminish, therefore near the central authorities of illuminating part laterally diffusion light not can by side frame body 2118 block, thereby can make task lighting device 2202d luminous intensity distribution expand.

Accordingly, at the edge of wanting to emphasize task illumination,, in the situation on the border of ambient lighting and task illumination, make the downward side frame body of solid-state light emitting element 2,211 2118 inner mobile, in the case of want to make the edge of task illumination soft, make to move near the lower end of solid-state light emitting element 2211 downward side frame bodies 2118, like this, can realize desirable lighting space.

Therefore,, according to the color temperature of the ambient lighting being detected by illumination condition detecting sensor 2203 and task illumination, can control the luminous intensity distribution of task illumination.Therefore, can reduce the large aberration of the marginal portion of causing because of the large photochromic difference between ambient lighting device and task lighting device, thereby can reduce the uncomfortable sensation of bringing because of user's inharmonious sense.Therefore, user's concentrated force can be improved, thereby mental labour productivity ratio can be improved.

Figure 26 is the skeleton diagram that the formation of the task lighting device that has adopted scattered reflection material and specular reflective material is shown.Task lighting device 2202e shown in Figure 26 possesses the optics (cartridge) 2240 being made up of scattered reflection material 2240a and specular reflective material 2240b.

; in order to improve the Efficiency Decreasing causing because of the multipath reflection in scattered reflection material 2240a; and the edge sense that improves range of exposures; in Figure 26; be provided with scattered reflection material 2240a at the inner face of optics (cartridge) 2240, and in a part for inner face, be provided with specular reflective material 2240b.Form according to this, that irradiate and at the light of the diffusion inside of optics (cartridge) 2240 by solid-state light emitting element 2211, reflect and be output to shadow surface one side by specular reflective material 2240b.Therefore, can export expeditiously the light irradiating from solid-state light emitting element 2211.

Figure 27 illustrates at the height h of optics (cartridge) 2240 is 30mm, be the relation of the width t of the specular reflective material 2240b 15mm and the center brightness rank of shadow surface from shadow surface side to the distance of specular reflective material installation site p.

Known according to figure, because luminous intensity distribution in the situation that there is no optics (cartridge) 2240 is large, therefore, center brightness is about 25cd/m ².The center brightness of the optics (cartridge) 2214 that inner face is made up of scattered reflection material 2240a is about 33cd/m ².In the optics (cartridge) 2214 being made up of scattered reflection material 2240a and a part of specular reflective material 2240b at inner face, in the situation that the width t of specular reflective material 2240b is 3mm, center brightness is about 33cd/m ², in the situation that the width t of specular reflective material 2240b is 6mm, center brightness is about 36cd/m ², in the situation that the width t of specular reflective material 2240b is 10mm, center brightness is about 35cd/m ².Therefore, in the time the width t of specular reflective material 2240b being set as to 3mm to 10mm and the ratio (t/h) of the height h of the width t of specular reflective material 2240b and optics (cartridge) 2240 is set as more than 1/10 below 1/3, can obtain appropriate center brightness rank.

And, Figure 28 A to Figure 28 E shows the Luminance Distribution in the cross section shown in the Figure 26 in following situation, and described situation is: the width t that the height h of optics (cartridge) 2240 is made as to 30mm, specular reflective material 2240b is made as 6mm and has changed the end face of shadow surface one side from optics (cartridge) 2240 shown in Figure 26 to the installation site p of specular reflective material 2240b.In Figure 28 A to Figure 28 E, transverse axis represents the mensuration distance apart from brightness center, and the longitudinal axis represents brightness.Figure 28 A shows the measured result in the situation that installation site p is made as to 0mm, Figure 28 B shows the measured result in the situation that installation site p is made as to 9mm, Figure 28 C shows the measured result in the situation that installation site p is made as to 12mm, Figure 28 D shows the measured result in the situation that installation site p is made as to 15mm, and Figure 28 E shows the measured result in the situation that installation site p is made as to 18mm.

By specular reflective material 2240b is installed, can know that the periphery at shadow surface edge and the poor of the intramarginal gray scale of shadow surface that comprises brightness center become large.In Figure 28 A and Figure 28 B, near the intramarginal brightness of shadow surface center, can see the part (part of so-called centre) that brightness reduces, and can confirm the difference of brightness.To this, in Figure 28 C, Figure 28 D and Figure 28 E, can confirm, in shadow surface edge, there is no large luminance difference, be almost the gray scale of homogeneous.Therefore, more than the preferred 12mm of installation site p as specular reflective material 2240b, and preferably in 12 to 18mm region.

And, as the method for luminous intensity distribution that expands task lighting device 2202, limit by above-mentioned method, also can adopt other method.

For example, (a) of Figure 29 is to the task lighting device 2302 shown in (c), by concave surface 2321a is set in the part at lower side frame body 2318, the jut 2321b of optics (cartridge) 2314 is embedded in to concave surface 2321a, thus the ligthing paraphernalia that can make optics (cartridge) 2314 be loaded and unloaded in the past.Accordingly, can switch wide-angle light-distribution and narrow angle luminous intensity distribution in the past, thus can be to needing the situation of concentrated force and the luminous intensity distribution of situation in addition to switch.

And, task lighting device 2402 that also can be as shown in Figure 30 (a) to (d), by arranging and slip into a mouthful 2422a at lower side frame body 2418, thus can storage light-emitting parts (cartridge) 2414.And, (d) of Figure 30 show by luminous component (cartridge) 2414 shown in Figure 30 (c) from above time figure after having rotated 90 degree.

The in the situation that of storage light-emitting parts (cartridge) 2414, as shown in Figure 30 (c), make to be arranged on the projection 2422d and the projection 2422c tabling that is installed in optics (cartridge) 2414 of a part that slips into mouthful 2422a.

And, in the situation that optics (cartridge) 2214 is outstanding, with the direction from top by luminous component (cartridge) 2414 90-degree rotations,, as shown in Figure 30 (d), be arranged on the projection 2422d and the projection 2422b tabling that is installed in optics (cartridge) 2214 of a part that slips into mouthful 2422a.

In the situation that chimeric position is switched, first with the direction from top, by optics (cartridge) 2214 90-degree rotations, chimerism is removed, after having adjusted height, again slip on 90-degree rotation one side on one side with the direction from top.And one end of projection 2422b, 2422c also can be used as brake component, to play the function of preventing rotating mechanism.By above formation, optics (cartridge) 2414 can be received to lower side frame body 2418.

In sum, by the related illuminator of present embodiment, the external equipments such as the PC that illuminator is used by user operate, and this external equipment and illuminator are received and dispatched by communication unit, thereby illumination is controlled, therefore can be controlled lighting space easily.And, by considered the control of the light that the display of PC exports at control part, thereby can more correctly control lighting space.And, by only communicating or communicate at equipment room, thereby can easily realize the lighting space that there is no inharmonious sense between each illuminator and data center.

And above-mentioned execution mode is an example, the utility model is limit by above-mentioned execution mode not.
