A case (10) for a portable electronic device (especially for an iPhone (100) and the like) comprises a shell (12), a diffuser (40) mounted within the shell (12), and an optional transparent insert (150) with custom graphics located between a front side (14) of the shell and the diffuser (40). The diffuser (40) comprises a Perspex panel having an etched portion (44) from which light escapes. The diffuser (40) may be slid between a position in which a flash (102) of the device is unobstructed, for normal photographic use, and a position in which light (200) from the flash (102) is received on a first surface (41) of the diffuser (40), whereby it is re-directed internally before being emitted from the etched portion (44) on the opposite, second surface (43) to provide even and bright illumination of that second surface.

1. A case for a portable electronic device, the case comprising: a shell defining an interior volume dimensioned so as to snugly accommodate a particular portable electronic device, wherein at least a portion of the shell is translucent or transparent; anda diffuser, visible through said translucent or transparent portion of the shell and configured to diffuse light incident on a first surface of the diffuser for emission from a second surface of the diffuser facing the translucent or transparent portion,wherein the portable electronic device includes a camera flash;wherein the diffuser comprises a panel of light-transmissive material received in a cavity in the shell; andwherein the diffuser is slidable within the cavity between a position in which light emitted by the flash is incident on the first surface of the diffuser and a position in which the diffuser does not interfere with light from the flash. 2. The case of claim 1, wherein the first surface of the diffuser is opposite to the second surface and faces the interior volume. 3. The case of claim 1, comprising a reflective layer disposed on the first surface of the diffuser. 4. The case of claim 3, further comprising a reflective layer disposed around the sides of the diffuser. 5. The case of claim 1, wherein the diffuser includes an etched portion in its second surface. 6. The case of claim 1, wherein the diffuser includes at least one lens element, configured to re-direct light incident on the lens element within the diffuser. 7. The case of claim 6, wherein the lens element comprises an indent cut into the first surface of the diffuser. 8. The case of claim 6, wherein the lens element comprises a reflective prism internally disposed in the diffuser from the second surface. 9. The case of claim 1, wherein the lens element is positioned so as to be in registration with a light source on the portable electronic device when received in the interior volume. 10. The case of claim 1, wherein the shell includes a window through which a display on the portable electronic device is visible when received in the interior volume. 11. The case of claim 1, further comprising a pocket interposed between the diffuser and the transparent or translucent portion of the shell for receiving a transparent graphic. 12. The case of claim 11, wherein the pocket includes a slot at one end through which transparent graphics can be slid, so as to enable their interchange. 13. The case of claim 1, wherein at least the translucent or transparent portion of the shell is formed of clear polycarbonate. 14. The case of claim 13, wherein the sides of the shell are formed of rubber, bonded to the polycarbonate portion. 15. The case of claim 1, wherein the portable electronic device is a mobile telephone. 16. The case of claim 1, further comprising a light source mounted to the shell for emitting light incident on the first surface of the diffuser. 17. The case of claim 16, wherein said light source comprises one or more LEDs or micro-LEDs mounted directly to the interior of the shell. 18. The case of claim 1, wherein the diffuser includes a slider accessible through a slot in a side of the shell for sliding the diffuser between said positions. 19. The case of claim 1, wherein the diffuser is configured for sliding motion within the cavity, such that the diffuser is selectively positioned within the cavity in a selected one of a diffusing position in which light emitted by the flash is incident on the first surface of the diffuser and a noninterfering position in which the diffuser is spaced apart from the flash such that light emitted by the flash is substantially separated from the first surface of the diffuser.
