no. 1 Embodiment approach

[0031] Hereinafter, the lighting fixture of 1st Embodiment is demonstrated using drawing.

[0032] Such as figure 1 (A) and figure 1 As shown in (B), the lighting fixture 10 according to the first embodiment is suitable for being attached to the ceiling surface 11 or the like as an attached portion and mainly illuminating the lower side.

[0033] Such as figure 2 As shown, the lighting fixture 10 has, for example, a disc-shaped fixture main body 20, and the disc-shaped fixture main body 20 has a mounting fitting 21 in the center for mounting to a ceiling hook portion 12 mounted on the ceiling. Surface 11. In addition, near the mounting bracket 21 at the central portion of the instrument main body 20, a control unit 23 is provided that receives power from the mounting bracket 21 and individually controls a plurality of light sources described later.

[0034] Operation of the control unit 23 can be performed by a remote controller (not shown), an operation panel (not show...

no. 2 Embodiment approach

[0071] Next, a lighting fixture according to a second embodiment will be described.

[0072] In addition, the same code|symbol is attached|subjected to the part common to the lighting fixture 10 of said 1st Embodiment, and overlapping description is abbreviate|omitted.

[0073] Such as Figure 9 As shown, in the lighting fixture of the second embodiment, when the indirect light emitting unit 30A reaches the full-brightness state and starts lighting the bulb-color LED of the direct-light emitting unit 40 at the bulb-color direct-light lighting start time T2, the control unit 23 gradually decreases the light quantity of the indirect light emitting portion 30A.

[0074] Then, when the light bulb color LEDs of the direct light emitting unit 40 are fully lit, the indirect light emitting unit 30A is turned off.

[0075] In addition, when the light bulb color LEDs of the direct light emitting unit 40 are fully illuminated and the white LEDs of the direct light emitting unit 40 are ...

Abstract

The invention provides a lighting fixture by which a sleeping person can be woken up comfortably at a preset time. A fixture body (20) can be attached to a ceiling surface (11), and an indirect light emitting unit (30A) which emits light along the ceiling surface and a direct light emitting unit (40) which emits light in a direction away from the ceiling surface are arranged on the fixture body. A control unit (23) which turns on, turns off and dims the indirect light emitting unit and the direct light emitting unit is arranged on the fixture body. The control unit has a wake-up mode as follows: at a preset lighting start time before a wake-up time, the indirect light emitting unit and the direct light emitting unit are turned on in a low light state with a light volume smaller than that in a high light state, and then the indirect light emitting unit and the direct light emitting are brightened. In the wake-up mode, the control unit firstly turns on the indirect light emitting unit in the low light state, and then turns on the direct light emitting unit in the low light state. Thus, the sleeping person is enabled to adapt to the light gradually, and wake up comfortably at the wake-up time.

Description

technical field [0001] One embodiment of the present invention relates to a lighting fixture capable of waking up a sleeping person by turning on a lamp at a predetermined time. Background technique [0002] Conventionally, there is known a lighting fixture that is installed on a ceiling surface of a bedroom or the like and is turned on at a predetermined time to wake up a sleeper (see, for example, Non-Patent Document 1). [0003] Such as Figure 11 As shown, in the lighting fixture described in Non-Patent Document 1, when going to bed, it gradually becomes dark from the sleep setting time, and the light is turned off. [0004] In addition, when getting up, the switch is turned on before the prescribed time (for example, 30 minutes) of the wake-up time, gradually becomes brighter after the prescribed time, and is fully lit at the wake-up time. Accordingly, the body is slowly transferred to the awakened state. [0005] Non-Patent Document 1: "Residential Lighting | LED Cei...
