As shown in FIG. 2, the output display section 30 </ b> A has a light guide plate 31 that is C-shaped (linear) as a whole, and LED light emission in which an LED 322 is mounted on a substrate 321 on an end face (end section) 311. Part 32 is attached. The outer surface 312 and the inner surface 313 of the light guide plate 31 are painted white to prevent light leakage.
A diffusion plate 33 exposed on the upper surface of the base 11 is attached to the upper side of the light guide plate 31, and a reflection plate 34 is attached to the lower side of the light guide plate 31.
The diffusion plate 33, the light guide plate 31, and the reflection plate 34 have the same shape in plan view.
As will be described later, in order to move a finger along the surface of the diffusing plate 33, the diffusing plate 33 can be provided to be depressed by one step from the surface of the base 11.

Therefore, as shown in FIG. 3, when the LED 322 of the LED light emitting unit 32 emits light in the longitudinal direction of the light guide plate 31, the light advances through the light guide plate 31, and part of the light is emitted from the diffusion plate 33 upward. Let A part of the light reaches the reflecting plate 34 downward and is reflected upward to cause the diffusion plate 33 to emit light.
At this time, the length of the light emitting portion L of the diffusion plate 33 is determined in accordance with the output of the LED 322.

As shown in FIGS. 2 and 3, a sensor substrate 35 having the same shape as the reflecting plate 34 is attached to the lower side of the reflecting plate 34.

Further, an ON / OFF switch 41 and an electrostatic sensor 36 of the output display unit 30A are connected to the control unit 40A.

Next, a dimming operation using the output adjustment device 20A will be described with reference to FIGS.
When the ON / OFF switch 41 is turned on (step S1), the control unit 40A determines whether or not it is turned on for the first time (step S2). If it is turned on for the first time, the output unit 44 is controlled to turn on the light source 131 of the luminaire 10A with the lowest illuminance (output) (step S3). If not turned on for the first time, the control unit 40A calls the final illuminance at the time of previous lighting stored in the storage unit 43, and uses the output unit 44 to supply power to the light source 131 so that the illuminance at the time of previous lighting is turned off.
