Embodiment 1

[0037] [summary]

[0038] First, use figure 1 The outline of the lighting device according to this embodiment will be described. figure 1 It is a schematic diagram showing the lighting system 10 according to this embodiment and its usage environment.

[0039] The lighting device 10 performs wake-up control for comfortably waking up the user 1 who is sleeping on the bed 2 . The wake-up control refers to controlling the dimming ratio (light output) of the lighting unit 11 of the lighting device 10 . In this example, if figure 1 As shown, the lighting device 10 is a desk lamp type lighting device (desk lamp), and is installed near the bed 2 . Specifically, the lighting device 10 is arranged at the bedside of the user 1 to illuminate the face of the user 1 .

[0040] The user 1 performs an input such as setting time through the input unit 13 of the lighting device 10 . The set time is the time when the user 1 wishes to wake up. The input setting time is displayed, for examp...

Embodiment 2

[0146] Next, the lighting system according to Example 2 will be described. In the first embodiment, the lighting device 10 alone performs the wake-up control. For this, in the lighting system according to this embodiment, multiple devices cooperate to perform the wake-up control. In addition, in the following description, the same code|symbol is attached|subjected to the same component as Example 1, and the description is abbreviate|omitted or simplified.

[0147] A schematic diagram of the lighting system 100 and its usage environment related to this embodiment is shown. Figure 16 It is a block diagram showing the functional configuration of the lighting system 100 according to this embodiment.

[0148] Such as Figure 15 as well as Figure 16 As shown, the lighting system 100 includes a lighting device 110 and a control device 20 that controls the lighting device 110 . The lighting device 110 is, like the first embodiment, a lamp-type lighting device. The control devic...

Embodiment 3

[0159] Next, the lighting system of Example 3 will be described. In the second embodiment, the control device controls one lighting device, but in the lighting system according to the present embodiment, the control device controls a plurality of lighting devices.

[0160] Figure 18 It is a schematic diagram showing the lighting system 200 according to this embodiment and its usage environment. Figure 19 It is a block diagram showing the functional configuration of the lighting system 200 according to this embodiment.

[0161] Such as Figure 18 as well as Figure 19 As shown, the lighting system 200 is provided with the lighting device 110, the lighting device 110a, and the control device 220 which controls the lighting device 110 and the lighting device 110a. In addition, the lighting device 110 and the lighting device 110a are the same as those of the second embodiment, and thus description thereof will be omitted.

[0162] Such as Figure 19 As shown, the control d...

Abstract

The lighting device (10) includes: a lighting unit (11) that emits lighting light; a timing unit (12) that counts the time; an input unit (13) that receives input from the user (1) to set the time; and a control unit (14) Control the lighting unit (11) according to the set time, and the control unit (14) performs wake-up control, that is, from the first time T1 to the second time T2 after the set time, the lighting unit (11 ) decreases the dimming ratio, and increases the dimming ratio from the second time T2 to the third time T3, and the control unit 14, in the wake-up control, when the dimming ratio is set to Y and the time is set to t, according to The dimming ratio from the second time T2 to the third time T3 is controlled by a function represented by constants a, b, c, and d, and the constant c is a value closer to the second time T2 than the third time T3.

Description

technical field [0001] The invention relates to a lighting device and a lighting system. Background technique [0002] Conventionally, lighting devices for realizing a comfortable light environment for occupants to wake up mainly in houses have been known. For example, Patent Document 1 discloses a wake-up device that gradually increases the light intensity from a time that is a certain time earlier than a designated wake-up time. [0003] However, according to the wake-up device described in Patent Document 1, a sleeper (so-called re-sleeping sleeper) who has overslept beyond the wake-up designated time cannot be woken up. In contrast, Patent Document 2 discloses a wake-up lighting device that intermittently gives light stimulation and sound stimulation after a designated wake-up time in order to wake up a sleeper who has been sleeping beyond the designated wake-up time. [0004] (Prior art literature) [0005] (patent documents) [0006] Patent Document 1: Japanese Pat...
