Abstract
The present invention is directed toward apparatuses, devices, methods, kits, programs, and combinations to disperse and/or project light. For example, in one embodiment of the present invention where a light effect of glowing, diffuse, and projected light is desired, one lens is provided that diffuses light in one section of the lens and is substantially clear in another section to allow substantially all the light to pass through the lens. In other embodiments to obtain the same effect, one or more lenses diffuse light while one or more other lenses are clear to allow substantially all the light to pass through the lens.
Claims20
A diffuser, comprising:
- a housing assembly having a compartment for receiving a container having a wick;
- a heating device disposed within the housing assembly at a position proximate to an upper portion of the wick;
- an electrical connection to transmit electricity to the diffuser;
- a light source comprising a light-emitting diode;
- and
- at least one lens to project light emitted from the light source from the diffuser.
A method of displaying light and dispensing a fragrance from a diffuser, the method comprises:
- providing the diffuser, the diffuser including a housing assembly having a reclosable compartment for at least one of receiving, releasably engaging, and retaining a container configured to contain the fragrance and an optional wick extending therefrom;
- a heating device disposed within the housing assembly at a position proximate to the container;
- a light source comprising a light-emitting diode;
- and at least one lens near the light source to display light;
- inserting into the compartment the container having an amount of the fragrance;
- providing a power source to the diffuser;
- and
- activating the heater and the light source to display the light through the at least one lens and to dispense the fragrance from the diffuser.
A multi-clarity lens for displaying light from a device to disperse active material, the multi-clarity lens comprising:
- a polypropylene lens comprising at least one section that is thicker and more opaque to light than at least one other section;
- wherein the device comprises a housing assembly having a compartment for at least one of receiving, releasably engaging, and retaining a container configured to contain the active material and an optional wick extending therefrom;
- a heating device disposed within the housing assembly at a position proximate to the container;
- a light source comprising a light-emitting diode;
- and at least one of the polypropylene lenses near the light source to display light.
