Abstract
Described herein are various configurations and designs for an external flash device. The external flash device can attach to a camera device, such as a mobile phone or smartphone, to provide enhanced flash performance to an internal flash of the camera device. An adjustable arm of the external flash device can include a sensor positionable to receive an optical transmission, such as a flash from the camera device. The adjustable arm can allow the external flash to function with various camera devices. In response to receiving and detecting the optical transmission, the external flash can activate one or more light emitting units to generate a flash that is synchronized with the capture of an image by the camera. One or more light emitting arrays can be included in the external flash to provide greater flash brightness or more than one color temperature of light emitting units.
