News editors obtained the following quote from the background information supplied by the inventors: "Existing electrical wiring at facilities typically require that power circuits are brought geographically throughout the facility. For example, a single circuit breaker may be dedicated to an area of offices and provide power for wall outlets, computers, copiers, printers and other office equipment, as well as lights. All of the equipment, including incandescent lights, are designed for and draw power from the sole source. Light Emitting Diode ('LED') lights have been available to replace incandescent lights; however, LED lights inherently are designed to operate off of a Direct Current (DC) circuit. A preferred power source for LED's is much like household batteries. The power is designed to originate at the source and travel to the application. Alternatively, Alternating Current (AC) circuits deliver power from the source to the application as well as delivering power downline to the next series of applications. Substantially the entire electrical infrastructure of existing facilities is wired via AC circuits. Therefore, a move to LED lighting products within an existing AC infrastructure requires some type of conversion of the power infrastructure.
"LED lighting bulbs have been developed for use with existing electrical infrastructures. These commercially available bulbs come with an AC/DC converter built into them. They are designed to plug into standard one hundred twenty volt AC (120VAC) lighting sockets that were originally designed for incandescent bulbs. The electronics built into the LED bulb convert the energy from AC to DC power for use with the LED bulb. However, the AC/DC conversion device built into the LED bulb, such as a bridge rectifier, does not allow the light bulb to operate at maximum efficiency. The micro processor performing the conversion generally consumes more energy (e.g., watts) than the actual light requires.
"The total amount of light produced by a light source such as an incandescent bulb or an LED bulb, without regard to direction, is measured in lumens. The amount of light produced by the light source in a specific direction is measured in candela and is graphically represented by polar-formatted charts that indicate the intensity of light at each angle away from 0.degree. lamp axis. The 0.degree. lamp axis is often referred to as the 'nadir,' which represents the direction pointing directly below a particular light source, and the tabular form typically includes candela output at n.degree. wherein n represents an angle measured from the 0.degree. lamp axis (i.e., from the direction pointing directly below a particular light source) and such angle can range from one side of the light source to the other side of the light source, from -90.degree. to +90.degree.
"The enclosures for standard electrical equipment, such as for example an AC/DC conversion device or a light bulb, are designed to prevent debris and moisture from entering therein, and are rated for a sealing effectiveness of such enclosures. Some industry standards have been adopted for water protection specifications for electrical device enclosures and are referred to herein. One such European Community Specification, IEC 529, provides a classification system for Ingress Protection, IP##. The first digit indicates the degree the enclosure is protected against the ingress of solid materials and ranges from 0 (no protection) to 6 (dust-tight). The second digit indicates the degree the enclosure is protected against the ingress of moisture and ranges from 0 (no protection) to 8 (protected against submersion). For example, a rating of IP64 indicates that such an enclosure exhibits an Ingress Protection that is dust-tight and protected against splashing water from all directions; while a rating of IP67 indicates that such an enclosure exhibits an Ingress Protection that is dust-tight and protected against the effects of short-term immersion. Other industry standards that have been adopted include specifications promulgated by the
