US Patent:

7230758, Jun 12, 2007

Filed:

Jun 30, 2005

Appl. No.:

11/171070

Inventors:

Yu Huang - Los Angeles CA, US

Assignee:

Luminoz, Inc. - Tokyo

International Classification:

G03B 21/60
G03B 21/56

US Classification:

359457, 359459, 359460

Abstract:

An off-axis Fresnel lens is disclosed that, when combined with a rear projection screen (comprising, e. g. , a lenticular lens, a diffuser, or both), enables construction of rear-projection-type screen devices (e. g. , projection television systems) that are thinner and have improved contrast and resolution when compared with conventional projection screen devices. The off-axis Fresnel lens comprises a plurality of concentric, outwardly-extending, total internal reflection-type prism facets. Each facet, in turn, comprises top and bottom sides, one or both of which may be flat or outwardly convex. Embodiments of the invention may also include concentric opaque sections that are disposed between successive prisms, between the prism base and the output surface of the Fresnel lens, and/or between the output surface of the Fresnel lens and the input surface of the projection screen in order to improve contrast. Contrast may also be enhanced by laminating the Fresnel lens to the projection screen.

US Classification:

359457, 359459, 359460

Abstract:

Off-axis total internal reflection Fresnel lenses and projection screens are disclosed that, when combined, enable construction of projection assemblies for rear-projection-type screen devices (e. g. , projection television systems) that are thinner, provide easier handling and maintenance, and have improved contrast, focusing, and resolution when compared with conventional projection screen devices. The off-axis Fresnel lens comprises a plurality of concentric, outwardly-extending, total internal reflection-type prism facets, the top side of which may be aspherical. Embodiments of the invention also include projection screens having at least one diffuser and one lenticular lens. In addition, one or more opaque layers may be used to improve contrast. The various components, e. g. , the fresnel lens, the diffuser, the lenticular lens(es), the opaque layer(s), etc.

Inventors:

Joshua Chen - Newport Beach CA, US
Yu Huang - Newport Beach CA, US

International Classification:

A61N 5/06

US Classification:

607090000

Abstract:

A lamp for providing light therapy includes an input circuit, an output circuit, and a signal processing circuit. The input circuit may include a user input for providing control signals to the signal processing circuit based on input at the user input from a user. The output circuit may include a light output configured to emit light at a level of at least 2,500 lux. The light output may include one or more white LEDs and may also include one or more color LEDs. The signal processing circuit is connected to the input circuit and the output circuit, and receives the control signals from the input circuit to control the output circuit based on the control signals. A memory may be provided in communication with the signal processing circuit. The memory may store a plurality of output modes, such as a light therapy mode. The light output may include a diffuser that is configured to diffuse the high-intensity light for effective use.
