In addition, light emitted from the first and second light sources via the first and second lighting covers of the ambient lighting units is uniformly radiated from the entire outer peripheral surfaces of the first and second lighting covers, so that soft brightness is achieved. A feeling can be produced, and the brightness feeling index can be improved. The lighting system is to install task lighting below the ambient lighting unit, since light emitted downward from substantially lower halves of the first and second lighting covers that define the arc of the ambient lighting unit becomes ambient lighting. Thereby, task / ambient lighting can be easily realized, and energy saving of the indoor lighting can be achieved while suppressing a decrease in the comfort of the occupants of the room.

Since the lighting system S1 can use the ambient lighting unit 10A as a ceiling surface, there is no need to install a ridge or a ridge receiver on the ceiling slab 12 of the room 11 or to install a ceiling board on the ridge. The ceiling surface can be easily constructed in the room 11.

  When the switch is turned on, the first and second light sources 28 and 32 (the first and second lighting devices 14 and 15) are turned on. When the first light source 28 is turned on, the first lighting cover 29 moves longitudinally forward from the lower end of the front wall 16 (below the first installation portion) toward the front end of the front extending top wall 24 (above the first installation portion). Since the arc is drawn so as to be convex, the light emitted from the first light source 28 irradiates downward (vertically) from the substantially lower half of the first illumination cover 29 as shown by the arrow Z in FIG. At the same time, as shown by an arrow X1 in FIG. 5, light emitted from the first light source 28 is emitted from a substantially upper half of the first illumination cover 29 in a longitudinally forward direction (horizontal direction). The light emitted from the first light source 28 is also applied in an oblique direction between a lower part (vertical direction) indicated by an arrow Z and a longitudinal front part (horizontal direction) indicated by an arrow X1.

  When the second light source 32 is turned on, the second illumination cover 33 moves in the longitudinal direction from the lower end of the rear wall 17 (below the second installation portion) toward the rear end of the rear extending top wall 25 (above the second installation portion). Since the arc is drawn so as to protrude backward, the light emitted from the second light source 32 is downwardly (vertically) from the substantially lower half of the second illumination cover 33 as shown by the arrow Z in FIG. At the same time, the light emitted from the second light source 32 is emitted from substantially the upper half of the second illumination cover 33 rearward in the longitudinal direction (horizontal direction) as indicated by an arrow X1 in FIG. The light emitted from the second light source 32 is also applied in an oblique direction between a lower part (vertical direction) indicated by an arrow Z and a longitudinal rear part (horizontal direction) indicated by an arrow X2.

  In the lighting system S1, the light emitted from the first and second light sources 28 and 32 illuminates the middle space and the bottom space of the room 11, and the light emitted from the first and second light sources 28 and 32 is ceiling. Illuminates nearby high-frequency space. In the lighting system S1 of FIG. 5, an office desk 38 is installed immediately below the ambient lighting unit 10A, and a desk light 39 serving as task lighting is placed on the office desk 38. The ambient lighting unit 10A and the desk light 39 are mounted. Thus, task ambient lighting is formed.

  The lighting system S1 (ambient lighting unit 10A) is configured such that the first lighting cover 29 of the first lighting fixture 14 of the unit 10A moves upward from below the front wall 13 (first installation portion) of the mounting base 13 in the longitudinal direction. An arc is drawn so as to be convex and extends in the short direction covering the first light source 28, and the second lighting cover 33 of the second lighting fixture 15 of the unit 10A is attached to the rear wall 17 of the mounting base 13 (second installation). Since the light source 30 draws an arc so as to protrude forward in the longitudinal direction from the lower part to the upper part and extends in the short direction covering the second light source 32, the light emitted from the first light source 28 is the first light. The light is emitted from the substantially upper half of the lighting cover 29 in the longitudinal direction forward, and the light emitted from the second light source 32 is emitted from the substantially upper half of the second lighting cover 33 in the longitudinal direction backward, and the first and second light sources 28, 32 By Luo emitted light illuminates the high spatial ceiling vicinity of the chamber 11, it is possible to brighten the high-frequency space in the ceiling near, it is possible to make indoor entire bright atmosphere.

  The lighting system S1 (ambient lighting unit 10A), when the resident looks at the room from one end of the room 11 to the rear in the longitudinal direction, substantially above the first lighting cover 29 as shown in FIG. Since the high-frequency space near the ceiling of the room 11 looks bright due to the light emitted from the half to the front in the longitudinal direction, it is necessary to reduce the difference in brightness between the high-frequency space near the ceiling and the middle or low-frequency space in the room. Without stressing residents. Further, when the resident looks at the room from the other end of the room 11 to the front in the longitudinal direction, the light emitted from the substantially upper half of the second lighting cover 33 to the rear in the longitudinal direction causes the vicinity of the ceiling of the room 11 Since the high-pass space looks bright, the difference in brightness between the high-pass space near the ceiling and the mid-pass or low-pass space in the room can be reduced, and the resident is not stressed.

  The illumination system S1 (ambient illumination unit 10A) emits light emitted from the first and second light sources 28 and 32 via the first and second illumination covers 29 and 33 that form arcs. , 33 are uniformly applied from the entire outer peripheral surface, so that a soft feeling of brightness can be produced and the brightness feeling index can be improved. The illumination system S1 (ambient illumination unit 10A) illuminates the middle space and the low-pass space of the room 11 with light emitted downward from substantially lower halves of the first and second lighting covers 29 and 33 that form an arc. Since the light becomes ambient lighting, task / ambient lighting can be easily realized by installing the desk light 39 (task lighting) below the ambient lighting unit, and the comfort of the occupants of the room 11 can be improved. Energy saving of indoor lighting can be achieved while suppressing loss.

  The first outlet 40 of the outlet module 55 is detachably formed at the lower end of the front wall 16 of the mounting base 13 (below the first installation portion) and extends in the lateral direction. The first outlet 40 blows air from the lower end of the first lighting cover 29 toward the outer peripheral surface 45 of the first lighting cover 29 into the room. The conditioned air supplied from the air supply duct to the outlet module 55 is supplied from the first outlet 40 into the room.

  The second outlet 41 is detachably formed at the lower end of the rear wall 17 of the mounting base 13 (below the second installation portion), and extends in the short direction. The second outlet 41 blows air from the lower end of the second lighting cover 33 toward the outer peripheral surface 46 of the second lighting cover 33 into the room. The conditioned air supplied from the air supply duct to the outlet module 55 is supplied from the second outlet 41 into the room. By removing the outlet module 55 (first and second outlets 40, 41) from the mounting base 13, the ambient lighting unit 10A of FIG. 1 can be obtained.

  The lighting system S2 shown in FIG. 8 is formed of a plurality of ambient lighting units 10B that are arranged in a line in the short direction and are separated by a predetermined distance in the longitudinal direction of the ceiling slab 12. The ambient lighting units 10B are suspended from the ceiling slab 12 using hangers 36 and suspension bolts 37 (suspension means), and form the ceiling surface of the room 11 (ceiling slab 12). The ambient lighting units 10B are located between both side edges of the ceiling slab 12 extending in the longitudinal direction and extend in the lateral direction. The ambient lighting units 10B have the same height (hanging height) from the floor surface 54, are installed parallel to the ceiling slab 12, and are adjacent to each other from the front in the longitudinal direction to the rear. Are arranged in parallel with each other.

  When the first light source and the second light sources 28 and 32 are turned on by turning on the switch, the light emitted from the first light source 28 of the ambient lighting unit 10B is transmitted to the first lighting cover 29 similarly to the lighting unit 10A of FIG. Of the first lighting cover 29 in the longitudinal direction (horizontal direction), and is emitted from the second light source 32 of the ambient lighting unit 10B. The light is emitted downward (vertical direction) from substantially the lower half of the second illumination cover 33 and is emitted backward (horizontal direction) in the longitudinal direction from the approximately upper half of the second illumination cover 33. Light emitted from the first and second light sources 28 and 32 is also applied in an oblique direction.

  In the lighting system S2, the light emitted from the first and second light sources 28 and 32 of the ambient lighting unit 10B illuminates the middle space and the bottom space of the room 11, and the first and second light sources 28 and 32 emit light. The emitted light illuminates the high-frequency space near the ceiling of the room 11.

  In the lighting system S2, the conditioned air generated by the air conditioner is supplied from the air supply duct to the ambient lighting units 10B. The conditioned air supplied to each lighting unit 10B from the air supply duct is blown into the room from the first air outlet 40 of the air outlet module 55 and is blown into the room from the second air outlet 41. The conditioned air blown out from the first outlet 40 is blown out from the lower end of the first lighting cover 29 toward the outer peripheral surface 45 of the first lighting cover 29 as shown by an arrow X3 in FIG. Due to the Coanda effect that flows along the outer peripheral surface 45 that forms the arc of 29, it flows along the outer peripheral surface 45 of the first lighting cover 29 and gradually diffuses forward in the longitudinal direction of the room through the high-frequency space near the ceiling. I do.

  The conditioned air blown out from the second outlet 41 is blown out from the lower end of the second lighting cover 33 toward the outer peripheral surface 46 of the second lighting cover 33 as shown by an arrow X4 in FIG. Due to the Coanda effect flowing along the outer peripheral surface 46 forming the arc of 33, the air flows along the outer peripheral surface 46 of the second lighting cover 33 and gradually diffuses rearward in the longitudinal direction of the room through the high-frequency space near the ceiling. I do.

  The lighting system S2 (ambient lighting unit 10B) has the following effects in addition to the effects of the lighting system (ambient lighting unit 10A). In the lighting system S2 (ambient lighting unit 10B), the air blown from the first and second outlets 40 and 41 flows along the outer peripheral surfaces 45 and 46 that define the arcs of the first and second lighting covers 29 and 33. The Coanda effect occurs, and the air flowing along the outer peripheral surfaces 45 and 46 of the first and second lighting covers 29 and 33 travels in the high-frequency space near the ceiling of the room 11 to be forward and backward in the longitudinal direction of the room. Since the air gradually diffuses into the room, the air supplied into the room can be spread evenly throughout the room. In the lighting system S2 (ambient lighting unit 10B), the air blown out from the first and second outlets 40 and 41 does not directly hit the occupants of the room 11, but the discomfort caused by the air directly hitting the occupants. Can be prevented.

In the ambient lighting unit 10C, the opening closing panel 21 is not provided in the lower opening 23 of the mounting base 13.

  The air conditioning module 47 is detachably installed (built-in) in the accommodation space 22 between the front wall 16 (first installation section) and the rear wall 17 (second installation section). A connection duct 44 for connecting an air supply duct (not shown) is attached to the top wall 18 of the mounting base 13, and outside air supplied from the air supply duct flows into the air conditioning module 47. The air conditioning module 47 takes in room air from the air inlet, adjusts (air-conditions) the temperature and humidity of the room air with the refrigerant coil, creates conditioned air, and outputs mixed air of the conditioned air and outside air from the air supply port. The first and second air flow paths 42 and 43 are supplied with air.

  The first outlet 40 is detachably formed at the lower end of the front wall 16 of the mounting base 13 (below the first installation portion), and extends in the short direction. The first outlet 40 blows air from the lower end of the first lighting cover 29 toward the outer peripheral surface 45 of the first lighting cover 29. The first air passage 42 is detachably formed immediately after the front wall 16 of the mounting base 13. The lower end of the first air flow path 42 is connected to the first outlet 40, and the upper part thereof is connected to the air supply port of the air conditioning module 47. The mixed air of the conditioned air and the outside air generated by the air conditioning module 47 passes through the first air passage 42 and is supplied into the room from the first outlet 40.

  The second outlet 41 is detachably formed at the lower end of the rear wall 17 of the mounting base 13 (below the second installation portion), and extends in the short direction. The second outlet 41 blows air from the lower end of the second lighting cover 33 toward the outer peripheral surface 46 of the second lighting cover 33. The second air flow path 43 is detachably formed immediately after the rear wall 17 of the mounting base 13. The lower end of the second air passage 43 is connected to the second outlet 41, and the upper end thereof is connected to the air supply port of the air conditioning module 47. The mixed air of the conditioned air and the outside air generated by the air conditioning module 47 passes through the second air passage 43 and is supplied into the room from the second outlet 41.

  The first flap 48 is detachably installed in the first air flow passage 42 near the first outlet 40. The first flap 48 is pivotable forward (horizontally) and downward (vertically) in the longitudinal direction, and changes the blowing direction of the conditioned air (mixed air) blown out from the first blowout port 40 to the front wall 16 (the second direction). (1 installation part) and change between below (vertical direction) and forward in the longitudinal direction (horizontal direction). The second flap 49 is rotatable back and forth in the longitudinal direction (horizontal direction) and downward (vertical direction), and is detachably provided in the second air passage 43 near the second outlet 41. The second flap 49 changes the blowing direction of the conditioned air (mixed air) blown out from the second blowout port 41 between the lower side (vertical direction) of the rear wall 17 (second installation portion) and the front side in the longitudinal direction (horizontal direction). Change between.

  By removing the air conditioning module 47 (first and second air passages 42 and 43, first and second outlets 40 and 41, refrigerant coil) and first and second flaps 48 and 49 from the mounting base 13, FIG. It can be one ambient lighting unit 10A.

  When the first and second flaps 48 and 49 are turned in the longitudinal direction, as shown by arrows X3 and X4 in FIG. 10, air-conditioned air (mixed air) during cooling is supplied from the first outlet 40 to the first lighting cover 29. , And flows toward the front in the longitudinal direction, and the conditioned air (mixed air) is blown out from the second outlet 41 toward the outer peripheral surface 46 of the second lighting cover 33 to be rearward in the longitudinal direction. Flows towards. The ambient lighting unit 10 </ b> C uses the first and second flaps 48 and 49 to direct the blowing direction of the cooling air toward the front in the longitudinal direction and the rear in the longitudinal direction during the cooling of the chamber 11, so that the first and second outlets are provided. The air blown out from the first and second lighting covers 29 and 33 has a Coanda effect in which the air blown from the first and second lighting covers 29 and 33 flows along the outer peripheral surfaces 45 and 46 that define the arcs of the first and second lighting covers 29 and 33. The cooling air flowing along the outer peripheral surfaces 45 and 46 is gradually diffused along the high-frequency space near the ceiling toward the front in the longitudinal direction and the rear in the longitudinal direction of the chamber 11, so that the cooling air can be distributed evenly throughout the room. .

  When the first and second flaps 48 and 49 are turned downward, as shown by arrows X5 and X6 in FIG. 11, the conditioned air (mixed air) during heating flows from the first outlet 40 toward the floor surface 54. While being blown out, it is blown out from the second blow-out port 41 toward the floor surface 54. The ambient lighting unit 10C prevents the stagnation of the heating air in the high-frequency space near the ceiling by using the first and second flaps 48 and 49 to direct the blowing direction of the heating air downward when the room 11 is heated. And the middle space and low space of the room 11 can be reliably heated.

  The lighting system S3 shown in FIG. 12 is formed of a plurality of ambient lighting units 10C that are arranged in a line in the short direction and are separated by a predetermined distance in the longitudinal direction of the ceiling slab 12. In FIG. 12, it is assumed that the first and second flaps 48 and 49 are turning in the longitudinal direction. The ambient lighting units 10C are suspended from the ceiling slab 12 using hangers 36 and suspension bolts 37 (suspension means), and form the ceiling surface of the room 11 (ceiling slab 12). The ambient lighting units 10C are located between both side edges of the ceiling slab 12 extending in the longitudinal direction and extend in the short direction. The ambient lighting unit 10C has the same height (hanging height) from the floor surface 54, is installed parallel to the ceiling slab 12, and is adjacent to each other from the front in the longitudinal direction to the rear. Are arranged in parallel with each other.

  When the first light source 28 and the second light source 32 are turned on by turning on the switch, the light emitted from the first light source 28 of the ambient lighting unit 10C is downward (vertically) from the substantially lower half of the first lighting cover 29. The light is radiated from substantially the upper half of the first lighting cover 29 to the front in the longitudinal direction (horizontal direction), and the light emitted from the second light source 32 of the ambient lighting unit 10C is substantially reduced to the lower half of the second lighting cover 33. The light is emitted downward (vertically) from above, and is emitted longitudinally rearward (horizontally) from substantially the upper half of the second illumination cover 33. Light emitted from the first and second light sources 28 and 32 is also applied in an oblique direction.

  In the lighting system S3, the light emitted from the first and second light sources 28 and 32 of the ambient lighting unit 10C illuminates the middle space and the bottom space of the room 11, and the first and second light sources 28 and 32 emit light. The emitted light illuminates the high-frequency space near the ceiling of the room 11. In the lighting system S3 shown in FIG. 12, an office desk 38 is installed immediately below the ambient lighting unit 10C, and a desk light 39 serving as task lighting is placed on the office desk 38, and the ambient lighting unit 10C and the desk light are mounted. 39 form task ambient illumination.

  In the lighting system S3, room air flows into the module 47 from the air intake of the air conditioning module 47, and the temperature and humidity of the room air are adjusted by the air conditioning module 47, and the temperature and humidity of the conditioned air (cooling air) are adjusted. ) And outside air are supplied to the first and second air passages 42 and 43 from the air supply port. The conditioned air (mixed air) is blown into the room from the first outlet 40 through the first air passage 42 and is blown into the room from the second outlet 41 through the second air passage 43. .

  The conditioned air (mixed air) blown out from the first blowout port 40 is blown out from the lower end of the first lighting cover 29 toward the outer peripheral surface 45 of the first lighting cover 29 as shown by an arrow X3 in FIG. Due to the Coanda effect flowing along the outer peripheral surface 45 that defines the arc of the first lighting cover 29, the room flows along the outer peripheral surface 45 of the first lighting cover 29 and travels along the high-frequency space near the ceiling of the room 11. 11 gradually diffuses forward in the longitudinal direction.

  The conditioned air (mixed air) blown out from the second outlet 41 is blown out from the lower end of the second lighting cover 33 toward the outer peripheral surface 46 of the second lighting cover 33 as shown by an arrow X4 in FIG. Due to the Coanda effect that flows along the outer peripheral surface 46 of the second lighting cover 33 that defines an arc, the room flows through the high-frequency space near the ceiling of the room 11 while flowing along the outer peripheral surface 46 of the second lighting cover 33. 11 gradually diffuses rearward in the longitudinal direction.

  The lighting system S3 (ambient lighting unit 10C) has the following effects in addition to the effects of the lighting system S1 (ambient lighting unit 10A). The lighting system S3 (ambient lighting unit 10C) includes a Coanda in which the conditioned air (mixed air) generated by the air conditioning module 47 flows along the outer peripheral surfaces 45 and 46 that define the arcs of the first and second lighting covers 29 and 33. The effect is generated, and the conditioned air (mixed air) flowing along the outer peripheral surfaces 45 and 46 of the first and second lighting covers 29 and 33 travels in the high-frequency space near the ceiling of the room 11 and is forward in the longitudinal direction of the room 11. Therefore, the air-conditioned air (mixed air) supplied to the room 11 can be spread evenly throughout the room.

  In the lighting system S3 (ambient lighting unit 10C), the mixed air of the conditioned air (cooling air) created by the air conditioning module 47 and the outside air directly hits the occupants of the room 11 from the first and second outlets 40 and 41. Therefore, discomfort due to the conditioned air (mixed air) directly hitting the occupants can be prevented. The lighting system S3 (ambient lighting unit 10C) can generate conditioned air (mixed air) by an air conditioning module 47 installed between the front and rear walls 16, 17 (first and second installation portions) of the mounting base 13. Therefore, the lighting unit 10C alone can supply the conditioned air (mixed air), and there is no need to separately provide an air conditioner and an air supply duct, so that the air conditioning equipment can be compactly and inexpensively constructed.
