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.

An audiovisual-capturing system for a lighted mirror is used to illuminate a user's face and aid in capturing images or video of the user through a one-way mirror. The system includes a support structure, a one-way mirror, and a plurality of lights. The support structure includes a bordering frame which attached around the one-way mirror. The plurality of lights is connected to the bordering frame and is distributed about the bordering frame. The plurality of lights is used to illuminate the user's face. The support structure also includes a device stand which is used to support an audiovisual-capturing device. The one-way mirror is positioned in between the device stand and the plurality of lights. This allows the audiovisual-capturing device to capture images or record video through the one-way mirror, while the user is able to see their reflection through the one-way mirror.

A lighting apparatus comprises a light panel having a panel frame, and a plurality of LEDs or other light elements secured to the panel frame. A self-contained battery unit securably attaches to the outside of the panel frame. The light panel may have a dimmer switch, and may also be capable of receiving power from a source other than the self-contained battery unit. The lighting apparatus can be mounted to a camera or a stand through adapters. Diffusion lenses or color gels can be integrated with or detachable from the light panel. The lighting apparatus may conveniently be provided in the form of a kit, with one or more of a light panel, self-contained battery unit, compact stand, connecting cable(s), adapter(s), lenses or color gels, and so on, provided in a single package.

A light source module for macro photography is disclosed. The light source module is for connecting to a lens of an image capturing apparatus and bearing against a plane surface to capture the image of the plane surface. The light source module includes a barrel, a contact unit and a lighting unit. The barrel has a rear portion for connecting to the lens and a front portion opposite to the rear portion. The contact unit is arranged on an end face of the front portion. The contact unit has a plurality of contact pads arranged at intervals on the end face for contacting with the plane surface. The lighting unit is arranged on the inner surface of the barrel.

The present invention relates to a fluorescence observation device, a domed base and a fluorescence microscope. The fluorescence observation device includes a dome, a multi-angle light-emitting unit and a controller unit. The dome includes a transparent thermal insulation layer and a heat sink layer. The multi-angle light-emitting unit includes multiple directional narrow light field electro-luminescence devices thermally connected to the heat sink layer and adapted to emit light at different angles to pass through the transparent thermal insulation layer. The narrow light field electro-luminescence devices are selectively activated to emit light by the controller unit, so that the illumination angle of the multi-angle light-emitting unit can be adjusted. The fluorescence observation device can be combined with a base to constitute the domed base. Alternatively, narrow light field electro-luminescence devices are mounted on the base.

A lighting apparatus comprises a light panel having a panel frame, and a plurality of LEDs or other light elements secured to the panel frame. Lenses and/or filters are adjusted in distance from the light elements, by for example moving the lenses/filters into different slot positions of the frame, to alter characteristics of the emitted light. Focal lenses, diffusion lenses, and color filters may be used individually or in combination. A compound lens includes lens elements having different characteristics arranged in a pattern. Through groupwise control of the intensity of the light elements, the different characteristics are emphasized or de-emphasized. The light panel may have an integrated battery, and may be mounted on a stand. The panel may be modular, allowing larger panels to be constructed from smaller panels.

An image taking device with a lighting device includes a light irradiating portion for irradiating light to a subject and a light receiving portion for receiving reflected light from the subject that is irradiated by the light. The light irradiating portion is structured to have a plurality of light sources that are arranged so as to surround the light receiving portion. Each of the light sources is adjusted to emit light of an intensity corresponding to an arrangement position.

A lighting effects system comprises an arrangement of lamp elements, such as light-emitting diodes (LEDs) or other light elements, on a panel or frame. The panel or frame may be relatively lightweight, and may include one or more circuit boards for direct mounting of the lamp elements. The panel or frame may have an opening through which a camera can view. A mounting bracket and assembly may be used for attaching the panel or frame to a camera. The lamp elements may be electronically controllable so as to provide differing intensity levels, collectively, individually, or in designated groups, and may be strobed, dimmed or otherwise controlled according to manually selected or programmable patterns. Different color lamp elements may be mounted on the same panel/frame, and, in particular, daylight and tungsten colored lamp elements may be mounted on the same panel/frame and their relative intensities selectively controlled by control circuitry.

A surveillence camera assembly with external adjusting ring has a camera and a cover. The camera comprises a lens assembly, two adjusting rings, a mounting ring. The lens assembly has a lens and two adjusting rod extending out of the lens and being capable of rotating around to adjust the lens. The mounting ring has two annular surfaces formed and extending from opposite ends. The two adjusting rings are rotatably mounted on a respective annular surface and have a clip formed on an inner surface to correspond and receive a free end of the adjusting rod of the lens such that rotation of the external adjusting rings will rotate the adjusting rod of the lens assembly to do adjustment.
