Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention attaches to an antenna of a mobile communication device that configures a line using radio waves while moving, such as a mobile phone or PHS, detects self-generated radio waves of the mobile communication device, lights a light emitting element, and transmits or The present invention relates to a device for displaying an incoming call with light.

[0002]

[Problems to be solved by the device]

 It is general to notify the incoming call to the telephone by sound, but it is easier to understand if the incoming call is notified by both sound and light. Especially when the surroundings are noisy, it is convenient to notify the incoming call with a light so that you can see it even if you cannot hear the sound. Also, when a call arrives in a dark place, the presence of the light makes it easy to find the location of the phone and makes it easier to operate. Some mobile phones, PHS, and other telephones have an incoming lamp, but most of them are inconspicuous due to insufficient light intensity or small light intensity.

The present invention has been made for the purpose of making it possible to optically notify a transmission or an incoming call without remodeling an existing telephone or adding a power source.
