It is formed in a flat plate shape extending in parallel to the mounting surface F such as a ceiling or wall. The side wall portion 103 is formed to extend in a direction orthogonal to the support portion 102 (in other words, the mounting surface F), and a part of the front end portion projects outward in the radial direction of the base body 101 to hold the cover. A portion 104 is formed.

  The cover holding part 104 is a plate-like part that detachably hooks and holds the cover 160. The support portion 102 composed of the support portion 102, the side wall portion 103, and the cover holding portion 104 is formed by integrally forming a metal plate, and then the first low activity light outward irradiator 110, the second low activity light outward irradiator 120, and utilization. The low active light L1 and the utilization light L2 respectively emitted from the light irradiator 120 are formed by coating in white so as to diffusely reflect. The control unit housing 105 is a part that houses a control unit 140 described later, and is configured by a hollow body that closes both ends of a resin-made cylindrical body.

  The first low active light outward irradiator 110 is a luminaire that irradiates low active light L1 having an emission peak in a wavelength region of 500 nm or more and 620 nm, and is mainly composed of a light source annular support 111 and a low active light source 113.

More specifically, the low-activity light L1 at which the insects are in a dormant state is a so-called light in which nocturnal insects mainly refrain from or pause activities such as movement, sucking, predation, mating, and egg-laying in a bright environment such as daytime. The light is in an adaptive state and is in the wavelength region of approximately 500 nm or more (green) and 620 nm (orange) or less. The low activity light L1 is indicated by a broken line in each figure.

It is formed in a cylindrical shape having a length longer than the width of the light source 113.

  On the outer peripheral surface of the light source annular support 111, each low activity light source 113 is attached via a strip-shaped flexible substrate (not shown) that supplies power to each low activity light source 113. The light source annular support 111 is fixedly attached to the support 102 by two attachment pieces 112 extending from the support 102 of the base body 101. In this case, the light source annular support 111 is attached to the support 102 of the base body 101 so that the axial direction is orthogonal. In addition, the mounting piece 112 supports the light source annular support 111 at a position that protrudes downward from the side wall portion 103 of the base body 101.

  The low active light source 113 is a light emitter that emits low active light L1 having an emission peak in a wavelength region of 500 nm or more and 620 nm. In the present embodiment, the low activity light source 113 is configured by an LED light emitting element (Light Emitting Diode) having an emission peak at a wavelength of 590 nm. In the present embodiment, the first low activity light outward irradiator 110 is configured by mounting 24 low activity light sources 113 on the outer peripheral surface of the light source annular support 111 at equal intervals. Further, the operation of each of these low activity light sources 113 is controlled by a control unit 150 described later.

  The second low activity light outward irradiator 120 is a luminaire that irradiates the low activity light L1 having an emission peak in the wavelength region of 500 nm or more and 620 nm, similar to the first low activity light outward irradiator 110, The light source annular support 130 and the low activity light source 121 are configured.

In the present embodiment, the low activity light source 121 is configured by an LED light emitting element (Light Emitting Diode) having a light emission peak at a wavelength of 590 nm, similar to the low activity light source 113. In the present embodiment, in the second low activity light outward irradiator 120, 24 low activity light sources 121 are attached to the outer peripheral surface of the light source annular support 130 at equal intervals. Further, the operation of each of these low activity light sources 121 is controlled by the control unit 150.

  Similar to the light source annular support 111, the light source annular support 130 is a component for supporting a plurality of low-activity light sources 121 and a plurality of utilization light sources 141 described later in a state of being annularly arranged. A metal plate extending in a cylindrical shape is formed. In this case, the light source annular support 130 is formed with a diameter capable of ensuring a clearance necessary for maintenance with respect to the light source annular support 111, and can hold each low-activity light source 121 and each utilization light source 141, respectively. It is formed in a cylindrical shape having a length longer than the widths of the low activity light source 121 and the utilization light source 141.

  The light source annular support 130 has the low-activity light sources 121 attached to the outer peripheral surface via band-like flexible substrates (not shown) that supply power to the low-activity light sources 121, respectively. Each light source 141 is attached to the inner peripheral surface via a strip-shaped flexible substrate (not shown) that supplies power to each light source 141. The light source annular support 130 is fixedly attached to the light source annular support 111 by two attachment pieces 131 extending from the light source annular support 111. In this case, the light source annular support 130 is attached to the support portion 102 of the base body 101 so that the axial direction is orthogonal. In other words, the light source annular support 130 is attached concentrically with the light source annular support 111 in this embodiment.

  Further, the mounting piece 131 supports the light source annular support 130 at a position protruding from the light source annular support 111 downward in the figure. Thereby, the low activity light source 121 is arranged in a position shifted to the outside in the central axis direction of the light source annular support 111 with respect to the low activity light source 113, in other words, below the low activity light source 113. It is arranged side by side at a position shifted to.

  The utilization light irradiator 140 is a luminaire that emits utilization light L2 having a color different from the emission peak of the low activity light L1, that is, an emission peak having a wavelength different from the emission peak of the low activity light L1, The light source annular support 130 and the utilization light source 141 are configured. Here, the utilization light L2 is light having a wavelength required for illumination by the user of the low attraction illumination device 100, for example, white light. That is, in the present embodiment, the utilization light source 141 is configured by an LED light emitting element (Light Emitting Diode) that emits white light.

  In this case, white light is light that is realized by a continuous spectrum over the entire visible light range, and is light that appears to be white to the human eye by mixing the three primary colors of light or mixing two colors that are complementary. is there. In this embodiment, the utilization light source 141 is covered with a resin-made translucent cover in which a yellow fluorescent material is applied to the outside of an LED light emitting element that emits blue light (wavelength range of about 420 to 470 nm). It is configured. In the present embodiment, the utilization light irradiator 140 is configured such that eighteen utilization light sources 141 are attached at equal intervals on the inner peripheral surface of the light source annular support 130. In addition, the operation of each of the utilization light sources 141 is controlled by the control unit 150 described later. In addition, utilization light L2 is shown with a broken line in each figure. In addition, the boundary between the low activity light L1 and the utilization light L2 is indicated by a broken line for convenience, but the actual boundary between both is gradually changed and is unclear.

  The control unit 150 includes a microcomputer, and is a device that controls the operations of the first low-activity light outward irradiator 110, the second low-activity light outward irradiator 120, and the utilization light irradiator 140, respectively. Housed in the housing 105. More specifically, the control unit 150 uses the detection signal from the approach detection sensor 151 in accordance with a control program (not shown) stored in advance in a storage device (for example, ROM) in the microcomputer, so that the first low-activity light outward irradiation is performed. The operation of the illuminator 110, the second low activity light outward irradiator 120, and the utilization light irradiator 140 is controlled. In the present embodiment, the control unit 150 always turns on the first low-activity light outward irradiator 110 and the second low-activity light outward illuminator 120 in a state where the power is ON, and causes the low-attraction illumination device 100 to On the other hand, the utilization light irradiator 140 is turned on only when an object enters a predetermined area.

  The approach detection sensor 151 is an object when an object such as a person or an object enters the area illuminated by the low-attraction lighting device 100, more specifically, the area irradiated with the utilization light L2 by the utilization light irradiator 140. This is a detector that outputs an electrical signal corresponding to the change in the number of incoming to the control unit 150 as an incoming detection signal. In the present embodiment, the approach detection sensor 151 is a so-called human sensor that senses heat (infrared rays) emitted from an object and outputs it as an approach detection signal. This intrusion detection sensor 151 is attached to the central portion of the support portion 102 of the base portion 101 via a support base 152 so that the region irradiated with the utilization light L2 by the utilization light irradiator 140 becomes the entry detection region. .

  In addition, the control unit 150 supplies power for driving the first low activity light outward irradiator 110, the second low activity light outward irradiator 120, the utilization light irradiator 140, and the intrusion detection sensor 152 to an external power source (for example, , A power supply unit 153 formed of an electric circuit for receiving from the power supply unit P connected to the 100V outlet) and an operator 154 for inputting an instruction to the control unit 150.

  In this case, the power supply unit 153 has an unillustrated connection terminal for electrically detachably connecting to the power feeding unit P from an end surface (the upper end surface illustrated) facing the mounting surface F side of the control unit housing 105. It is provided in an exposed state. In addition, the operator 154 can adjust and set the detection sensitivity of the approach detection sensor 152, the lighting time or lighting illuminance of the utilization light irradiator 140 within a predetermined range.

  The cover 160 transmits the low activity light L1 and the utilization light L2 emitted from the first low activity light outward illuminator 110, the second low activity light outward illuminator 120, and the utilization light illuminator 140, respectively. It is a part that detachably covers the inner side, and is composed of a milky white translucent resin material having a water-drop-shaped cross section. That is, the cover 160 reduces the directivity of the low activity light L1 and the utilization light L2 emitted from the first low activity light outward illuminator 110, the second low activity light outward illuminator 120, and the utilization light illuminator 140, respectively. In other words, a part of the low activity light L1 and the utilization light L2 is diffusely reflected and the other part is transmitted.

  In this case, the cover 160 can be formed of, for example, a so-called satin having a plurality of irregularities formed on the surfaces through which the low activity light L1 and the utilization light L2 are transmitted. The cover 160 can also be configured by, for example, applying a light scattering agent (for example, a pigment containing magnesium carbonate, titanium oxide, or the like) to the surfaces through which the low activity light L1 and the utilization light L2 are transmitted. In addition, a through-hole is formed in the center of the cover 160 so that the intrusion detection sensor 152 passes through and is exposed to the outside.

(Operation of the low-attraction lighting device 100)
Next, the operation of the low attractive lighting device 100 configured as described above will be described. First, the installer who installs the low-attraction lighting device 100 attaches the low-attraction lighting device 100 to the mounting surface F. In this case, the low-attraction lighting device 100 is attached to a mounting surface F such as a wall such as a staircase or a passage that is open to the outdoors in a building, or a ceiling. In the present embodiment, the installer installs the low-attraction lighting device 100 on the ceiling surface in the vicinity of the front door of each door of a shared passage in an apartment house such as an apartment or a condominium. Specifically, the installer connects the power supply unit 153 of the low attractive lighting device 100 to the power supply unit P provided on the attachment surface F. Thereby, the low-attraction lighting device 100 is attached to the attachment surface F and is in a state where power can be supplied to the control unit 150.

  Next, the installer sets the operation specifications of the utilization light irradiator 140 with respect to the control unit 150. Specifically, the installer sets the detection sensitivity of the intrusion detection sensor 152, which is a condition for turning on the use light irradiator 140, the lighting time from the start of lighting to turning off, and the illuminance in the control unit 150 via the operation unit 154. To do. Thereby, the control part 150 controls the action | operation of the utilization light irradiation device 140 according to the set operation specification.

  Next, the user of the low attraction lighting device 100 starts using the low attraction lighting device 100. Specifically, the user supplies power to the control unit 150 by turning on a power switch (not shown) provided on the common passage where the low-attraction lighting device 100 is installed. As a result, the control unit 150 receives the power supply from the power supply unit 153 and starts operation. Specifically, the control unit 150 turns on the first low-activity light outward irradiator 110 and the second low-activity light outward illuminator 120 by executing a control program stored in advance in the storage device, and enters the The detection signal from the detection sensor 151 is input and the operation control of the utilization light irradiator 140 is started.

  Thereby, as shown in FIG. 3, the low-attraction lighting device 100 is configured such that the low-activity light L <b> 1 irradiated from the low-activity light source 113 and the low-activity light source 121 respectively radiates the inner wall surfaces of the base body 101 and the cover 160. The light is emitted toward the outside through the cover 160 while being diffusely reflected. In this case, the cover 160 is mainly a portion corresponding to the first low activity light outward irradiator 110 and the second low activity light outward irradiator 120 (other than the circular portion directly below the light source annular support 130 on the outer surface of the cover 160). ) Is surface-emitted by the low activity light L1. For this reason, the low attraction illumination device 100 irradiates the low activity light L <b> 1 toward the outside of the cylindrical region immediately below the light source annular support 130. Thereby, the low attraction lighting device 100 can suppress the attraction and activity of insects existing around the low attraction lighting device 100 by the low activity light L1.

  On the other hand, the low-attraction lighting device 100 is directly below the low-attraction lighting device 100, that is, when an object such as a person enters the irradiation area of the utilization light irradiator 140 for a certain period of time, Based on the detection signal, the control unit 150 turns on the utilization light irradiator 140. In this case, the low-attraction lighting apparatus 100 uses the light irradiator in a state where the cover 160 is emitting light in a ring shape by turning on the first low-activity light outward illuminator 110 and the second low-activity light outward illuminator 120. 140 irradiates utilization light L2. For this reason, as shown in FIG. 4, the low-attraction lighting device 100 has a low-attraction by irradiating the utilization light L <b> 2 in a circular shape from the center of the cover 160 where the low-activity light L <b> 1 is emitting in a ring shape. The low activity light L1 is irradiated to the front (downward in the drawing) region of the sexual illumination device 100 so as to surround the periphery of the irradiation region of the utilization light L2.

  As a result, the low-attraction lighting device 100 irradiates a person positioned directly below the low-attraction lighting device 100 with light (utilization light L2) that is brighter than the low-activity light L1 and easy to see at hand. By covering the surroundings with the low activity light L1, it is possible to suppress the attraction and active activity of insects such as pests (for example, unpleasant pests, agricultural pests, sanitary pests, and pests that prey on these pests). Then, when the object such as a person no longer exists in the irradiation area of the utilization light irradiator 140, the low attraction illumination device 100 turns off the utilization light irradiator 140 by the control unit 150. Thereby, the low attraction illumination apparatus 100 returns to the lighting state of the 1st low active light outward irradiator 110 and the 2nd low active light outward irradiator 120 before making the utilization light irradiator 140 light. Such continuous lighting of the first low active light outward irradiator 110 and the second low active light outward irradiator 120 and intermittent lighting of the utilization light irradiator 140 are continued until the user turns off the power switch. The
