Abstract
An illumination device includes a detector configured to detect that a mobile terminal device has entered a communication area corresponding to the device, and a light irradiator configured to emit light for guiding a person with the mobile terminal device detected by the detector. The light irradiator emits light indicating a route through which the person with the mobile terminal device should proceed.
Claims5
An illumination device comprising:
- a detector configured to detect that a mobile terminal device has entered a communication area corresponding to the device;
- and
- a light irradiator configured to emit light for guiding a person with the mobile terminal device detected by the detector, wherein
- the light irradiator emits light indicating a route through which the person with the mobile terminal device should proceed,
- the light irradiator includes a light source and a light modulator configured to deform light from the light source into an elliptical shape, and
- the light modulator deforms the light so that a long axis direction of the elliptical shape is aligned with a proceeding direction through the route.
An illumination system comprising a plurality of illumination devices each including a detector and a light irradiator, the detector being configured to detect that a mobile terminal device has entered a communication area corresponding to the device, the light irradiator being configured to emit light for guiding a person with the mobile terminal device detected by the detector, wherein
- the illumination devices are provided along a route through which the person with the mobile terminal device should proceed,
- the light irradiator of each of the illumination devices emits light indicating a route through which the person with the mobile terminal device should proceed,
- the light irradiator includes a light source and a light modulator configured to deform light from the light source into an elliptical shape,
- the light modulator deforms the light so that a long axis direction of the elliptical shape is aligned with a proceeding direction through the route, and
- parts of communication areas corresponding to adjacent illumination devices among the illumination devices overlap each other.
