A low-glare fluorescent-powder LED light device includes a shell, a multi-frequency directional light source, a high-frequency directional light source, and an electrical control circuit. The shell has a surrounding wall, which defines a front opening and a rear opening and has an inner surface extending along a central axis. The multi-frequency directional light source, including at least one fluorescent-powder LED, is disposed at the inner surface of the shell. The high-frequency directional light source, including a plurality of high-frequency LEDs, is disposed at the inner surface of the shell such that the high-frequency LEDs are arranged in radial symmetry about the central axis. The electrical control circuit can drive the multi-frequency directional light source and/or the high-frequency directional light source. The central light beams emitting from the high-frequency LEDs do not reach the fluorescent-powder LED, so that the fluorescence interference of the fluorescent-powder LED can be avoided.

In one aspect, the present invention is directed to a photo terminal stand system, comprising: a light-opaque case, in which a front facet thereof is a tempered one-way reflective mirror; a display, mounted behind the one-way mirror, such that a graphical presentation presented by the display is seen outside the case through the one-way mirror; a camera, mounted behind the one-way mirror, for taking a stills photo or a video sequence; an input device using an infrared touch overlay frame, for providing coordinates of the mirror on which a user touches; and a computer, configured to receive from the input device which a user touches the coordinates thereof and responsively generate the graphical presentation, and activate the camera to record an image or a video sequence, wherein the system is adapted to convert the coordinates of a point the user touches on the mirror to the coordinates of the display.

An illumination apparatus includes a light source, a light-receiving unit, and a light guide unit formed in an arc shape. The light guide unit includes a light incidence section on which light from the light source is incident. The light incidence section is disposed on an outer circumferential side of the light guide unit, and faces the light source. The light guide unit further includes a first reflecting section having a first and a second region, and a second reflecting section having first and second surfaces. The first surface reflects the light incident from the light incidence section toward the first region, and the second surface reflects the light incident from the light incidence section toward the second region. The light-receiving unit is disposed at a position between the first and the second surfaces.

A lens apparatus includes an image pickup optical system; a holding frame to hold the image pickup optical system; and an illumination device that is mounted on outer peripheral portion of an object side of holding frame, and is configured to radiate light, in which the illumination device includes: a light guide member that has a circular optical path in which light is subjected to internal reflection to propagate, and a light emitting surface for emitting light to object side; and a light source that is arranged such that a normal direction of a light emitting surface of the light source faces a tangential direction of a circle of light guide member, and is configured to emit light entering the light guide member. The arrangements and shapes of holding frame, light guide member, and lens closest to object side of image pickup optical system are each appropriately set.

A lens apparatus includes: an image pickup optical system; a holding frame that holds the image pickup optical system; and an illumination apparatus that is attached to an outer peripheral portion of an object side of the holding frame and applies light. The illumination apparatus includes light sources and a light guide member that causes internal reflection of light from the light sources so that the light propagates. The light guide member has an annular shape and has a light exit surface from which light is emitted toward an object side. A distance DL between two closest light sources in the light sources, an internal diameter D of the plurality of light guide member, and a distance WD from the light guide member to an object at a closest distance when the image pickup optical system is focused on the object at the closest distance are appropriately set respectively.

An asymmetric aperture device for a camera is provided that improves light gathering properties by increasing both the light gathering opening of the aperture and the number of light producing light sources placed on the aperture. An asymmetric aperture design is provided that utilizes a significantly larger portion of the camera lens. The tradeoff between the competing objectives of maximizing camera depth of field and maximizing the production of useful focus-condition information within the camera image is optimized. More illumination is provided without significantly increasing the lateral size of the illuminator pattern.
