Abstract
According to an aspect, a control device for an illumination device includes: a touch sensor and a display panel. A light diffusion degree setting screen for executing light diffusion degree setting processing for the illumination device is displayed on a display region of the display panel. The light diffusion degree setting screen is provided with a light distribution shape object with a central point at the origin of an XY plane, a first light diffusion degree setting object with a central point at an intersection point of an X axis of the XY plane and an outline of the light distribution shape object, and a second light diffusion degree setting object with a central point at an intersection point of a Y axis of the XY plane and the outline of the light distribution shape object.
Claims22
A control device for an illumination device capable of controlling a light distribution state of light emitted from a light source in two directions of a first direction and a second direction intersecting the first direction, the control device comprising:
- a touch sensor having a detection region provided with a plurality of detection elements;
- and
- a display panel provided with a display region overlapping the detection region of the touch sensor in a plan view, wherein
- a light diffusion degree setting screen for executing light diffusion degree setting processing for the illumination device is displayed on the display region of the display panel, and
- an X direction corresponding to the first direction, a Y direction corresponding to the second direction, and an XY plane with an origin at a predetermined position on the light diffusion degree setting screen are defined for the light diffusion degree setting screen, and
- the light diffusion degree setting screen is provided with
- a light distribution shape object with a central point at the origin of the XY plane,
- a first light diffusion degree setting object with a central point at an intersection point of an X axis of the XY plane and an outline of the light distribution shape object, and
- a second light diffusion degree setting object with a central point at an intersection point of a Y axis of the XY plane and the outline of the light distribution shape object.
An illumination system comprising:
- an illumination device including a light source and an optical element provided on an optical axis of the light source and capable of controlling a light distribution state of light emitted from the light source in two directions of a first direction and a second direction intersecting the first direction;
- and
- a control device configured to control the illumination device to change the light distribution state, wherein
- the control device includes
- a touch sensor having a detection region provided with a plurality of detection elements, and
- a display panel provided with a display region overlapping the detection region of the touch sensor in a plan view,
- a light diffusion degree setting screen for executing light diffusion degree setting processing for the illumination device is displayed on the display region of the display panel, and
- an X direction corresponding to the first direction, a Y direction corresponding to the second direction, and an XY plane with an origin at a predetermined position on the light diffusion degree setting screen are defined for the light diffusion degree setting screen, and
- the light diffusion degree setting screen is provided with
- a light distribution shape object with a central point at the origin of the XY plane,
- a first light diffusion degree setting object with a central point at an intersection point of an X axis of the XY plane and an outline of the light distribution shape object, and
- a second light diffusion degree setting object with a central point at an intersection point of a Y axis of the XY plane and the outline of the light distribution shape object.
