  • Patent number: 10558107
    Abstract: A flash system for an electronic device includes a ring-shaped light guide having a central opening. A camera lens is positioned in or behind the opening. A first light emittting diode (“LED”) is mounted on a printed circuit board (“PCB”), and the LED and PCB are encapsulated by a molded light guide of the flash system. An identical LED and PCB are encapsulated at an opposite end of the molded light guide (i.e., 180 degrees away). The back surfaces of each PCB diffusively reflects light from the LED on the other PCB. Light extraction features on the light guide surface uniformly leak out light from the LEDs. The light emission profile of the light guide has a peak axially aligned with the central opening of the light guide and rolls off to the edge of the camera's field of view.

  • Patent number: 9158180
    Abstract: A light focusing device for detachably coupling to a camera with a built-in flash. The device comprises a mount for detachably coupling to the camera; a housing coupled with the mount, the housing configured to enclose the built-in flash when the built-in flash is an enabled position; and a lens coupled with the housing such that light generated by the built-in flash is focused by the lens such that intensity of the light is increased farther away than what the built-in flash is able to do on its own.

  • Patent number: 9016882
    Abstract: A strobe device of the present invention includes a flash discharge tube having an anode electrode and a cathode electrode on both ends thereof, and a conductive reflector in contact with an outer peripheral surface of the flash discharge tube. The reflector houses a part of the flash discharge tube inside, and functions as an external trigger electrode. The reflector has a bottom that is in contact with a portion of the outer peripheral surface of the flash discharge tube, the portion covering at least an area between the anode electrode and the cathode electrode and a sintered metal of the cathode electrode. This can suppress variation in discharge path at every light emission from the flash discharge tube. As a result, variation in light quantity and variation in light distribution of light emitted from the strobe device can be suppressed.

The diffuse reflection lamp comprises a reflective plate (10), a connector (20) and a dragging device (40). The reflective plate (10) is removably fixed on the lamp by the connector (20) to reflect the light from the lamp. One end of the dragging device (40) is connected with the reflective plate (10), and the other end is connected with the connector (20); or the dragging device (40) hoops around the outer edge of the reflective plate (10). Therefore, the reflective plate (10) is elastically bended toward and formed into a curved arc surface to collect the diffuse reflection light.
