Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a dimmer that facilitates continuous dimming and stepwise dimming.

(Prior Art) Small dimmers generally used in offices, stores, etc. are limited to either continuous dimming or stepped dimming.

(Problem to be Solved by the Invention) However, while continuous dimming alone can adjust the brightness to the desired level, if you try to save power by making it brighter or darker depending on the number of customers in a store, for example, Having to adjust the brightness by operating the controls each time is not only troublesome, but also
There is a risk that it will not be possible to save power by fixing the brightness. Furthermore, since step dimming only allows adjustment of the brightness set in advance, there is a risk that the desired brightness may not be obtained and that sufficient power savings may not be achieved.

The present invention has been made in consideration of the above-mentioned circumstances, and allows easy switching between continuous dimming and stepped dimming using a changeover switch, and prevents undesired changes after setting the level of stepped dimming. It is an object of the present invention to provide a dimmer that can prevent such problems.

[Structure of the Invention] (Means for Solving Problems) The present invention provides a continuous dimming control section, a stepped dimming control section, and a changeover switch for selectively inserting and removing these dimming control sections, and The operating bodies for the dimming control unit and the changeover switch are arranged on the front of the main body, and the operating bodies for operating the continuous dimming control unit and the changeover switch, respectively, protrude from the front of the main body. It is characterized in that the step dimming operation body is covered with a plate from which the operation body protrudes.

(Function) In the dimmer of the present invention, when setting the stage dimming level, the plate is removed, the stage dimmer operating body is operated to set the desired level, and the plate is attached.
This prevents undesired changes in the step dimming operation body.

The switching operation body and the continuous dimming operation body are protruded from the plate, so if you want to set the brightness to your desired level, switch the switching operation body to continuous dimming and operate the continuous dimming operation body. The brightness can be adjusted to any desired brightness.

Further, when dimming to a preset brightness, the brightness can be dimmed to the preset brightness by operating the switching operation body and switching to the setting level of the step dimming control section.

Reference numeral 9 denotes a support, and these insulating plate 18 and support 19 are provided with holes through which the continuous dimming control section 5, staged dimming control section 6, and operation sections of the changeover switch 8 project, and are disposed in the main body section 1. There is. 20 is a cylindrical continuous dimming operation body that controls the continuous dimming control unit 5 by rotating, for example; 21 is a rod-shaped stepped dimming operating body that controls the stepped dimming control unit 6 by rotating, for example; It is provided on the front surface of the main body 1 together with a switching operation body 13 for operating the switching switch 8 . The continuous dimming operation body 20 and the switching operation body 13 are formed to protrude from the front surface of the main body portion 1. In addition, the step dimming operation body 2
1 is formed without protruding from the front surface of the main body 1, and can be disposed between the stage dimming operation body 21 and the switching operation body 13 so as to be covered by a plate 25, which will be described later. Furthermore, the step dimming operation body 21
The notch 22 may be provided on the front surface so that it can be operated only with a screwdriver, thereby preventing the set dimming level value from being changed due to undesired rotation. . Then, one of the step dimming operation bodies 21 is set to the first one with a dimming value of 40%, for example.
It is desirable to set the second brightness to 70% in advance, and set the other brightness to a second brightness, for example, 70%. 23 is a boss portion, which includes a hole passing through the continuous dimming operating body 20 and the switching operating body 13, and a stepped dimming operating body 21.
The main body part 1 has a hole through which it is exposed, and is protruded from the front surface of the main body part 1, and is detachably attached to the support 18. 24 is a plate frame attached to the main body 1;

is the power supply.

Next, the operation of this embodiment will be explained. When setting the step dimming level, remove the plate 25, rotate the step dimming operation body 21 with a screwdriver or the like to adjust to the desired level, and then attach the plate 25. Thereby, undesired changes in the step dimming operation body 21 can be prevented. Then, switch operation body 1
3 from the off state of the first contact 9 to continuous dimming, the second contact 10 of the changeover switch 8

Therefore, for example, in a store, power can be saved by switching the switching operation body 13 to step-by-step dimming depending on the number of customers, thereby adjusting the light in the store step-by-step. In addition, when you want to set the brightness to a desired level during entertainment events, continuous dimming is possible by switching the switching operation body 13 to continuous dimming, and adjusting the brightness to your desired brightness by operating the continuous dimming operation body 20. can do. Further, when changing the step dimming level value, it can be easily changed by removing the plate 25 and operating the step dimming operation body 21.
