An LED light bulb for use as an indicator or warning lamp comprises a support structure; a generally circular and planar disc attached to the support structure, wherein the disc is a printed circuit board and is perpendicularly oriented with respect to the structure. A plurality of interconnected LEDs are concentrically mounted on the disc wherein a portion of the LEDs are outwardly splayed at an angle away from a central axis point of the disc so that the LEDs collectively transmit light having about the same light intensity at viewing angles from about 0.degree. to about 360.degree. about the disc. The LED light bulb has circuitry means for providing a current to the LEDs.

The invention pertains to electronic devices capable of dynamically changing their ornamental or decorative appearance, i.e., the outer appearance as seen by a user. The electronic devices generally include an illuminable housing. The illuminable housing, which includes at least one wall configured for the passage of light, is configured to enclose, cover and protect a light arrangement as well as functional components of the electronic device. The light arrangement, which generally includes one or more light sources, is configured to produce light for transmission through the light passing wall(s) of the illuminable housing. The transmitted light illuminates the wall(s) thus giving the wall a new appearance. That is, the transmitted light effectively alters the ornamental or decorative appearance of the electronic device. In most cases, the light is controlled so as to produce a light effect having specific characteristics or attributes. As such, the electronic device may be configured to provide additional feedback to the user of the electronic device and to give users the ability to personalize or change the look of their electronic device on an on-going basis. That is, a housing of the electronic device is active rather than passive, i.e., the housing has the ability to adapt and change. For example, the light may be used to exhibit a housing behavior that reflects the desires or moods of the user, that reflects inputs or outputs for the electronic device, or that reacts to tasks or events associated with operation of the electronic device.

A personal computing device is disclosed. The personal computing device includes a housing having a translucent portion. The housing encloses internally various components that provide computing operations for the personal computing device. The personal computing device also includes a light source disposed inside the housing. The light source is configured to produce light inside the housing so as to illuminate at least a portion of the translucent portion. The illumination of the translucent portion affecting the appearance of the housing in a non trivial manner.

One aspect of the invention pertains to a stiffener for a computer housing so as to increase the rigidity and strength of the computer housing.

A computing device is disclosed. The computing device includes a housing having an illuminable portion. The computing device also includes a light emitting device disposed inside the housing. The light emitting device is configured to produce a light effect that alters the ornamental appearance of the computing device.
