Appl. No.:

09/703088

Inventors:

Jeffery R. Parker - Strongsville OH
Mark D. Miller - Parma OH
Thomas A. Hough - Lakewood OH

Assignee:

Solid State Opto Limited

International Classification:

G01D 1128

US Classification:

362 29, 362 27, 362 30, 362 23, 116286

Abstract:

Light emitting panel assemblies include in one form of the invention a light emitting panel member made of a transparent resiliently deformable elastomeric material that absorbs impact without breakage for use in automotive lighting applications of various types. In another form of the invention, a rigid light emitting panel member may be used with dome switches for switch area lighting or to backlight control buttons/key pads by providing holes or openings in the panel member for the control buttons/key pads. Also, a rigid light emitting panel member may be used as a structural member, and two or more such light emitting panel members may be stacked together and used to light an instrument panel or the like. One or more light sources may be mounted within one or more light transition areas adjacent one or more light input surfaces of the light emitting panel members. Also one or more light sources may be positioned adjacent one side of the light emitting panel members for causing light to shine through the panel members or through holes in the panel members for performing specified lighting functions.

International Classification:

G02B 620

US Classification:

385133, 385125, 385901, 362559

Abstract:

An illuminated surgical retractor includes a handle having an elongated first blade portion connected at one end to one end of the handle and an elongated second blade portion extending along the length of the first blade portion. One end of the second blade portion defines an illumination input end to which a connector is coupled. The connector is shaped to optically couple the illumination input end to a source of illumination so that at least a portion of one of the first and second blade portions is illuminated.

Inventors:

Jeffrey B. Williams - Ravenna OH
Robert Caywood - Vermilion OH
Jeffery R. Parker - Richfield OH

Assignee:

Lumitex, Inc. - Strongsville OH

International Classification:

G02B 610

US Classification:

385123, 385124

Abstract:

Light delivery systems/lighting devices include a light distributor and a flexible light emitter. A malleable member adjacent said light emitter is bendable to hold the shape of the light emitter once arranged in a desired position. A protective cover protects the light emitter and/or light distributor from direct contact with contaminants or components which may interfere with proper operation thereof. A handle connected to the light distributor contains a light pipe or rod that provides an interface between the light distributor and a light source conduit which may be inserted into a socket in the handle or connected to a male adaptor mounted in the socket.

International Classification:

F21V 704

US Classification:

362 31, 362330, 362332, 362339

Abstract:

Light emitting panel assemblies include a light emitting panel member having a uniform or variable pattern of light extracting deformities of well defined shapes in or on one or more surface areas of the light emitting panel member. The size and shape as well as the depth and angular orientation and position or location of the light extracting deformities may vary along the length and/or width of a panel surface area to obtain a desired light output distribution from the panel surface area. Also, at least some of the deformities may have planar surfaces in parallel spaced relation to a panel surface area. A focused light source may be insert molded or cast within a light transition area of the light emitting panel member to focus the light on an input surface of the light transition area with predetermined ray angles to fit a particular application. Molded supports may be provided on the panel member for supporting other parts or components in spaced relation therefrom. In another embodiment of the invention, an array of light sources may be mounted on a printed circuit board for directing light through a diffuser or lens mounted in spaced relation to the light sources for use in phototherapy treatment or the like.

International Classification:

F21V 800

US Classification:

362 31, 362 26

Abstract:

Optical assembly includes a light emitter and a film through which light passes from the light emitter. The film has a uniform or variable pattern of individual deformities of well defined shape that are projections or depressions on or in one or more surface areas of the film. The deformities are quite small in relation to the width and length of the film. At least some of the deformities may have two or more surfaces that come together to form a ridge having a total length that is quite small in relation to the width and length of the film.

International Classification:

F21V 704

US Classification:

362 31, 362330

Abstract:

Light redirecting films include a pattern of individual optical elements of well defined shape on the light exit surface of the films for refracting the light entering the entrance surface of the films from a backlight toward a direction normal to the exit surface. The individual optical elements overlap and intersect each other. Also, the orientation, size and/or shape of the optical elements may be tailored to redirect more of the incident light from the backlight within a desired viewing angle.

US Classification:

362 31, 362 27, 362235, 362297, 362308

Abstract:

Light emitting panel assemblies include a sheet, film or plate overlying a light emitting member. The sheet, film or plate has a pattern of deformities on one or both sides that may vary or be random in size, shape or geometry, placement, index of refraction, density, angle, depth, height and type for controlling the light output distribution to suit a particular application. Also the sheet, film or plate may have a coating or surface treatment for causing the light to pass through a liquid crystal display with low loss.
