Abstract
In one embodiment of the invention, photo-chromic applicators are disclosed. The photo-chromic applicator may include a liquid photo-chromic material such as a photo-chromic ink or paint. The photo-chromic material is applied to a surface of a toy, a page, or other object by a child user. The photo-chromic material may be activated in various ways with various light activating devices that can generate the activating light with appropriate wavelengths.
Claims18
A photo-chromic application set comprising:
- a substrate provided on a three dimensional structure or a portion thereof;
- a writing instrument including photo-chromic material, the writing instrument to apply one or more layers of the photo-chromic material on the substrate;
- and
- wherein shining an activating light on a portion of the one or more layers of photo-chromic material temporarily changes the activated portion.
A method of applying photo-chromic material comprising:
- moving a tip of a writing instrument on a surface to apply a photo-chromic material, the photo-chromic material having an initial state;
- shining an activating light to activate the photo-chromic ink applied to the surface;
- and
- viewing the surface including the photo-chromic ink applied thereto to detect a change in the initial state of the photo-chromic ink.
A combined activating light and photo-chromic applicator comprising:
- a photo-chromic material applicator to apply a photo-chromic material on a surface;
- a housing coupled to the photo-chromic material applicator, the housing having a first end and a second end opposite the first end, the housing to receive one or more batteries as a power source;
- an ultraviolet light emitting diode (UVLED) mounted in the housing at the first end, the UVLED to generate a wide angle activation light around an optical axis in response to receiving power from the one or more batteries;
- and
- a switch mounted to the housing, the switch to switch the power from the one or more batteries ON and OFF to the UVLED.
