For example, a GaN-based blue LED chip that emits blue light is used as the LED chip, and the wavelength conversion member can emit light of daylight white or light bulb color to the translucent resin material for sealing. For this purpose, a phosphor mixed with the phosphor is used. In addition, the color temperature of the light which the general light source 31 and the condensing light source 32 irradiate should just be a daylight color-light bulb color (color temperature 7100K-2600K). In the general light source 31, for example, an LED chip that emits daylight white light having a color temperature of about 5000K is suitably used for the LED group 31a that emits light having a relatively high color temperature. For the LED group 31b that emits light having a relatively low color temperature, for example, an LED chip that emits light bulb color light having a color temperature of about 2700 to 3000K is preferably used.

In addition, each LED in each LED group 31a, 31b may be configured so that further partial lighting or thinning lighting can be performed by grouping individually or in groups.

  The substrate 23 is provided with a control unit 24 for controlling the lighting of each light source 3. The control unit 24 turns on or off each light source 3 based on the radio signal received from the remote controller 11. The wireless communication referred to here includes infrared rays, radio waves, and visible light. In addition, the dimming control of each light source 3 is performed by the control unit 24, for example, PWM (Pulse Width Modulation) control or analog dimming control. The control unit 24 is realized by the microcomputer 24a. The dimming ratio means the ratio of the luminance with respect to the maximum luminance of each light source 3.

In addition to the dial tone, the buzzer 24c outputs a stimulating sound that makes sleep of the sleeper shallow.

  In addition, a sensor unit 6 is provided on the outer periphery of the fixture body 2 to detect the movement of a person who is indoors where the lighting fixture 1 is provided. The sensor unit 6 may be configured separately from the lighting fixture 1. The sensor unit 6 is configured by, for example, a motion sensor, and detects a wake-up preliminary action such as turning a sleeping person (user 10 (see also FIG. 1)) and detects the depth of sleep of the user 10. The sensor unit 6 determines that sleep is shallower as there is more movement such as turning over, and sleep is deeper as there is less movement.

  The cover 5 has a dome shape that covers the front surface of the instrument body 2 and is formed of a resin material obtained by adding light diffusing particles, pigments, or the like to a translucent material such as an acrylic resin. The cover 5 is obtained by subjecting the surface or back surface of a transparent glass plate or resin plate to a rough surface by applying a sandblasting treatment or a textured surface, instead of adding the above light diffusing particles or pigments. Alternatively, a fine irregular shape formed by dimple processing or the like may be used.

  Operation | movement of the lighting fixture 1 comprised in this way is demonstrated with reference to FIG.3 and FIG.4. The luminaire 1 includes a wake-up mode in which the user 10 operates the remote controller 11 to gradually increase the dimming ratio of the light source 3 when the user 10 goes to sleep, and each light source 3 when the user 10 wakes up. The dimming ratio is gradually decreased, and a rest mode in which the light is turned off after a predetermined time is executed. Here, the control of the waking mode will be described.

  The user sets a wake-up setting time t1 at which he / she wants to wake up and a period before waking up until the wake-up mode activation time t2. When performing the lighting control of the light source 3 in the wake-up mode, the control unit 24 gradually increases the illuminance at the beginning of the wake-up mode start time t2 and approaches the wake-up set time t1, as shown in FIG. Increase illuminance sharply. When the wake-up set time t1 elapses, the illuminance is gradually increased again, and then the illuminance is rapidly increased again. When the set reference illuminance is reached, the illuminance is maintained.

  Further, the controller 24 temporarily raises the dimming ratio of the light source 3 higher than the average dimming ratio in the period before waking up as shown in FIG. Control light stimulation intermittently. In addition to or instead of the light stimulus control, sound stimulus control for causing the buzzer 24c (sound source) to output a stimulus sound is intermittently performed as shown in FIG. The sound stimulus control is effective, for example, when the user 10 is wearing a futon from the head. Therefore, the sensor unit 6 may detect whether or not the user 10 is wearing a futon from the head, and may perform sound stimulation control based on the presence or absence of the detection.

  As described above, in this embodiment, at least one of the light stimulus control and the sound stimulus control is intermittently performed in the pre-wake-up period, so that even when the sleeper is deeply asleep at the wake-up mode start time t2, As the set time t1 is approached, the sleep of the sleeper is made shallower. As a result, the sleeping person can obtain a comfortable feeling of awakening by light stimulation with illumination light.

  Moreover, in light stimulus control, by irradiating light of high color temperature from each light source 3, when the user 10 wakes up, the user 10 can be awakened psychologically in awakening. In addition, the light stimulus control is performed by the condensing light source 32, so that it is easy to secure the sleeper's facial illuminance, and the sleep of the user 10 during the period before waking up can be more effectively reduced. Even when the luminaire 1 does not include the condensing light source 32, the sleep of the user 10 can be made shallow by the general light source 31 irradiating light with a high color temperature. Even when the luminaire 1 does not include the condensing light source 32, the sleep of the user 10 can be made shallow by the general light source 31 irradiating light with a high color temperature.

  Further, as shown in FIG. 4A, the control unit 24 adjusts the light source 3 (condensing light source 32) in the light stimulus control according to the sleep depth of the user 10 detected by the sensor unit 6. You may change the time or frequency | count of performing light ratio or light stimulus control. Further, the output of the stimulation sound in the sound stimulation control or the time or the number of times of performing the sound stimulation control may be changed. That is, when the user 10 is deeply asleep, a large stimulus is applied to effectively reduce the sleep of the user 10 by the wake-up set time t1. In addition, when the user 10 is lightly asleep, the user 10 can be provided with a comfortable awakening with less stress by giving a small stimulus.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. In the said embodiment, although the structure which used LED for each light source was shown, it replaced with LED and the module comprised by solid light emitting elements other than LED, such as an organic EL element (OLED) or an inorganic EL element, was used. Also good. Further, instead of the remote controller 11, an information communication terminal such as a smart phone or a tablet terminal may be used. In this case, the lighting fixture 1 is applied as a partial configuration of a lighting system including an information communication terminal.
