CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 60/858,558, filed Nov. 13, 2006, the entirety of which is incorporated herein by reference.
FIELD OF THE INVENTION(S) The present inventive subject matter relates to lighting devices which include solid state light emitters. In some aspects, the present inventive subject matter relates to lighting devices which include LEDs and/or lumiphors.
Color reproduction is typically measured using the Color Rendering Index (CRI Ra). CRI Ra is a modified average of the relative measurement of how the color rendition of an illumination system compares to that of a reference radiator when illuminating eight reference colors, i.e., it is a relative measure of the shift in surface color of an object when lit by a particular lamp. The CRI Ra equals 100 if the color coordinates of a set of test colors being illuminated by the illumination system are the same as the coordinates of the same test colors being irradiated by the reference radiator. Daylight has a high CRI (Ra of approximately 100), with incandescent bulbs also being relatively close (Ra greater than 95), and fluorescent lighting being less accurate (typical Ra of 70-80). Certain types of specialized lighting have very low CRI (e.g., mercury vapor or sodium lamps have Ra as low as about 40 or even lower). Sodium lamps are used, e.g., to light highways�driver response time, however, significantly decreases with lower CRI Ra values (for any given brightness, legibility decreases with lower CRI Ra).
BRIEF SUMMARY OF THE INVENTION(S) According to a first aspect of the present inventive subject matter, there is provided a lighting device, comprising:
BRIEF DESCRIPTION OF THE DRAWING FIGURES FIG. 1 is a sectional view of a first embodiment of a lighting device according to the present inventive subject matter.

A statement herein that two components in a device are �electrically connected,� means that there are no components electrically between the components, the insertion of which materially affect the function or functions provided by the device. For example, two components can be referred to as being electrically connected, even though they may have a small resistor between them which does not materially affect the function or functions provided by the device (indeed, a wire connecting two components can be thought of as a small resistor); likewise, two components can be referred to as being electrically connected, even though they may have an additional electrical component between them which allows the device to perform an additional function, while not materially affecting the function or functions provided by a device which is identical except for not including the additional component; similarly, two components which are directly connected to each other, or which are directly connected to opposite ends of a wire or a trace on a circuit board or another medium, are electrically connected.
As used herein, the term �substantially,� e.g., in the expressions �substantially equal�, �substantially uniform�, �substantially aligned�, �substantially parallel�, �substantially planar�, �substantially circular�, �substantially square�, etc., means at least about 95% correspondence with the feature recited, e.g., �substantially equal� means that the respective values differ by not more than 5%; �substantially uniform� means that 95% of the structure have values which differ from an average value by not more than 5%; �substantially aligned� means that a line connecting any pair of points and a line connecting any other pair of points define an angle not greater than 5% of 90 degrees, i.e., 4.5 degrees; �substantially parallel� means that two planes diverge from each other at most by an angle of 5% of 90 degrees, i.e., 4.5 degrees; �substantially flat� means that at least 95% of the points in the surface which is characterized as being substantially flat are located on one of or between a pair of planes which are parallel and which are spaced from each other by a distance of not more than 5% of the largest dimension of the surface; �substantially circular� means that a circle can be drawn having the formula x2+y2=1, where imaginary axes can be drawn at a location where the y coordinate of each point on the structure is within 0.95 to 1.05 times the value obtained by inserting the x coordinate of such point into such formula; and �substantially square� means that the shape can be placed on x,y coordinates such that and each point on the shape has an x coordinate or a y coordinate which is within 0.95 to 1.05 times a particular value or the negative of that value, and the absolute value of neither the x coordinate nor the y coordinate exceeds the absolute value of 1.05 times such particular value.

In some embodiments of the present inventive subject matter, the optical device in the lighting device, or one or more of the optical devices in the lighting device is substantially disc-shaped. The expression �disc-shaped�, as used herein, generally means a shape which has two major surfaces and one or more edge surfaces located between the two major surfaces. In some instances, the major surfaces are substantially flat, and/or substantially parallel to each other, and/or the overall �disc-shaped� structure has a plane of substantial symmetry. Such disc-shaped structures can have one or two major surfaces which are of any desired shape, e.g., substantially circular (i.e., the structure is substantially circular disc-shaped), substantially square (i.e., the structure is substantially square disc-shaped), etc.
A representative example of a suitable material out of which the reflector can be made is a material marketed by Furukawa (a Japanese corporation) under the trademark MCPET�.
