The present invention relates to an illumination apparatus for adjusting light dispersion and brightness for an electronic device having a light source and, more particularly, to an attachable and detachable apparatus for converting an electronic device having a light source commonly used as a camera flash into a dual-functional flashlight and lantern with adjustable light emission. Light dispersion and brightness is controlled by sliding a handle to position a lens farther or closer to the light source of the electronic device. The illumination apparatus has an adjustable clamp, by which an electronic device of varying dimensions is secured. The electronic device may be a mobile phone, smartphone, tablet computing device, or the like.
Portable electronic devices, such as mobile phones, smartphones, tablet computers, and the like, have become ubiquitous for communication, entertainment, and other purposes. As their use as digital cameras has grown increasingly important to their function, the integration of a bright light source such as a light emitting diode (LED) for photographic flash into the design of portable electronic devices has become standard. A variety of software has been developed to use this light source for functions other than photographic flash. For example, the user of a smartphone may use the built in LED as a crude flashlight to see in the dark.
