It is an image figure which shows the case where the illumination system which concerns on Embodiment 2 is provided in the room where the user has entered.

(Knowledge that became the basis of the present invention)
In a general lighting device, for example, when the AC drive frequency is 50 Hz, the frequency is 100 times per second (flashing frequency is 100 Hz), and when the frequency is 60 Hz, the frequency is 120 times per second (flashing frequency is 120 Hz). Has been done. Since blinking that can be perceived by humans is known to be less than 100 times per second, that is, the blinking frequency is less than about 100 Hz, the frequency of blinking in a general lighting device is human (user). It is set so that it is not perceptible or difficult to perceive.

  On the other hand, it is known to give psychological brightness to humans by using an illumination device that utilizes the Broca-Sulzer effect. The Blocker Salzer effect is a human physiological visual characteristic related to the perception of brightness, and is a phenomenon in which the perception of brightness changes with the time of flashing light.

  For example, when the user is irradiated with light with a constant brightness, the apparent brightness increases with the presentation time as the presentation time (flashing time) increases, and reaches a maximum after a predetermined time. After that, it may drop and eventually reach a certain level. In particular, when the presentation time is about 50 ms to 100 ms, the user feels that the brightness perceived by the eyes is brighter than the physical luminance.

  From such a viewpoint, blinking the light emitted from the light source does not give the person anxiety, etc., but intentionally blinking the light emitted from the lighting device for a predetermined time, so that the user can visually observe it. I want to give an easy perceptual effect.

  Then, this invention provides the illuminating device and illumination system which can improve a user's visibility.

(Embodiment 1)
[Constitution]
First, the structure of the illuminating device 1 which concerns on this Embodiment is demonstrated using FIG.

  FIG. 1 is a block diagram showing a lighting device 1 according to the present embodiment.

  As shown in FIG. 1, the illuminating device 1 is provided on the ceiling in the room, illuminates the room, and detects the movement operation of the user in the room. The lighting device 1 includes a light source module 20, a sensor 3 (acquisition unit), a control unit 4, a power supply unit 5, and an operation unit 6.

  The light source module 20 is a device that emits light of different colors, and includes a plurality of light sources 2. The plurality of light sources 2 are, for example, a plurality of red light sources 2a (an example of a light source) that emit red light, a plurality of green light sources 2b (an example of a light source) that emit green light, and a plurality of blue light sources 2c (a light source) that emit blue light. Example). The red light source 2a, the green light source 2b, and the blue light source 2c are so-called SMD (Surface Mount Device) type LED elements. The light source module 20 is turned on and off by being controlled by a control circuit provided in the lighting device 1. In the light source module 20, the control circuit controls the power supply unit 5 (by adjusting the amount of power supplied) to perform dimming control (brightness control) and toning control (emission color control). It emits light. The control circuit is realized by, for example, a microcomputer, a processor, a dedicated circuit, or the like that controls a current value supplied to the light source module 20 in accordance with an input signal. The control circuit may be provided in the control unit 4 or may be separate from the control unit 4. Hereinafter, each light source 2 or a plurality of light sources 2 is used to include a red light source 2a, a green light source 2b, and a blue light source 2c.

  The light source module 20 is not limited to such a configuration, and a COB (Chip On Board) type module in which an LED chip is directly mounted on a wiring board may be used.

  Note that the light source module 20 may include a plurality of light sources 2 having different color temperatures. That is, the light source 2 is not limited to the red light source 2a, the green light source 2b, and the blue light source 2c. In this case, for example, when emitting light having a color temperature different from that of the first light source among the plurality of light sources 2, the first light source and the second light source are alternately (staggered), The color temperature may be changed.

  The sensor 3 is provided in the lighting device 1 and can detect a moving operation of the user, and is, for example, a human sensor or an image sensor. The sensor 3 transmits information indicating that the detected moving operation is being performed to the control unit 4. The movement operation of the user is an operation including at least one of standing, sitting, walking, and turning over, and is a movement of the trunk, but may include an action of moving only the hand, foot, head, and the like. In addition, standing and sitting includes an operation of moving from a posture in which a person stands to a sitting posture and an operation of moving from a posture in which a person sits to a standing posture. In addition, although it may be considered that the user moves in a sitting position on the wheelchair, in this case, the movement of the wheelchair is regarded as walking. When the imaging unit is an image sensor, the captured information may be a moving image, for example.

  In the present embodiment, the lighting device 1 is integrally provided with the sensor 3, but the sensor 3 is a separate body independent of the lighting device 1, and is, for example, a sensor sheet laid on the floor of the room. A known sensor may be used as long as it is a sensor that detects the movement of the user. In this case, the sensor 3 transmits information indicating that it is moving to the lighting device 1 via a communication unit such as an antenna. In addition, providing integrally does not mean that the sensor 3 is electrically connected via a wired cable, but is provided in a state accommodated in the lighting device 1.

  When the control unit 4 receives information indicating that the user detected by the sensor 3 is moving, the control unit 4 transitions to a visibility enhancement mode for improving the visibility. The visibility enhancement mode is a mode in which visibility is improved by alternately switching the color of light emitted from the light source module among the light of a plurality of colors in the light source module 20.

  For example, alternately switching the color of light emitted from the light source module 20 may be realized by blinking some colors of light. Specifically, in the visibility enhancement mode, for example, red light, which is a part of red light, green light, and blue light constituting white light, is blinked at a frequency of less than 100 Hz. Green light and blue light are always turned on or blinked at a frequency of 100 Hz or more. In this case, the light appears alternately white and cyan. By blinking the color of the light, the user feels that the contrast of the color affects the human visual characteristic and the hue contrast becomes clear. In other words, the improvement in visibility means that the boundary between colors is felt to be clear. The color contrast effect is an illusion that, when an object with different colors is arranged, each hue appears to move in the opposite direction of the hue circle due to the influence of the surrounding hue. For example, when red light, which is a part of red light, green light, or blue light, is blinked at a frequency of less than 100 Hz, the hue of the object rises, Is clarified and the outline of the object appears to rise clearly.

  The means for alternately switching the color of light emitted from the light source module 20 may be realized by alternately switching the light emitted from a plurality of light sources having different color temperatures.

  The control unit 4 has a timer function, and starts to measure time when switching is started when the color of light emitted from the light source module 20 is switched. The control unit 4 determines whether or not a predetermined time has elapsed from the start of measurement, and ends the light switching when the predetermined time has elapsed. The predetermined time is a time set in advance, but may be arbitrarily set by the user. Further, the control unit 4 may realize these operations by, for example, a microcomputer, a processor, or a dedicated circuit that controls a current value supplied to the light source module 20 in accordance with an operation input from the operation unit 6. . In the present embodiment, the method of alternately switching the color of light emitted by the light source module 20 is, for example, red light, green light, or blue light with red light that is a part of the color being less than 100 Hz. This is done by blinking at a frequency.

  The power supply unit 5 includes, for example, a case made of insulating resin, which is a power supply box, and a power supply circuit arranged in the case. The power supply circuit is a circuit unit that includes a circuit board and circuit components mounted on the circuit board, and supplies power to the light source module 20 to light (emit) the light source module 20. For example, the power supply unit 5 converts the power supplied from the power system into a predetermined level of DC power by rectification, smoothing, and stepping down, and supplies the DC power to the light source module 20. The light source module 20 emits light by direct current power supplied from the power supply circuit.

  The power supply unit 5 is controlled by the control unit 4 to turn on and off the power supply to the light source module 20. For example, when a lighting operation is received through the operation unit 6 such as a remote controller, the control unit 4 supplies power from the power supply unit 5 to the light source module 20 to turn on the light source module 20. When the operation unit 6 receives an operation for turning off the light, the control unit 4 turns off the light source module 20 by cutting off the supply of power from the power supply unit 5 to the light source module 20.

  The operation unit 6 is an operation terminal such as a remote controller capable of performing operations such as dimming, toning, lighting and extinguishing of the lighting device 1. The operation unit 6 is changed to the visibility improvement mode manually or automatically by the user's operation.

  On the other hand, if the control unit 4 does not receive information indicating that the user is moving from the sensor 3 (NO in step S3), the control unit 4 repeats the determination in step S3.

  Next, the control unit 4 determines whether or not a predetermined time has elapsed since the start of blinking (step S5).

  Next, when it is determined that the predetermined time has elapsed since the start of blinking (YES in step S5), the control unit 4 controls the blinking color light so as to end the blinking. Then, the process returns to step S2.

  On the other hand, when it is determined that the predetermined time has not elapsed since the start of blinking (NO in step S5), the control unit 4 returns to step S3.

  Although the end of the step is not described in this flow, the end of the step may be performed by an operation in which the user turns off the lighting device 1 via the operation unit 6.
