As indicated above, some embodiments of the lighting assemblies according to the present inventive subject matter can include lumiphors (i.e., luminescence region or luminescent element which comprises at least one luminescent material). The expression �lumiphor�, as used herein, refers to any luminescent element, i.e., any element which includes a luminescent material.
For example, U.S. Pat. No. 6,963,166 (Yano '166) discloses that a conventional light emitting diode lamp includes a light emitting diode chip, a bullet-shaped transparent housing to cover the light emitting diode chip, leads to supply current to the light emitting diode chip, and a cup reflector for reflecting the emission of the light emitting diode chip in a uniform direction, in which the light emitting diode chip is encapsulated with a first resin portion, which is further encapsulated with a second resin portion. According to Yano '166, the first resin portion is obtained by filling the cup reflector with a resin material and curing it after the light emitting diode chip has been mounted onto the bottom of the cup reflector and then has had its cathode and anode electrodes electrically connected to the leads by way of wires. According to Yano '1166, a phosphor is dispersed in the first resin portion so as to be excited with the light A that has been emitted from the light emitting diode chip, the excited phosphor produces fluorescence (�light B�) that has a longer wavelength than the light A, a portion of the light A is transmitted through the first resin portion including the phosphor, and as a result, light C, as a mixture of the light A and light B, is used as illumination.
at least one heat dissipating fin; an annular region; at least one heat conducting element; an annular element; a heat sink structure; and/or at least one solid state light emitter. The heat dissipating fins and the annular region can be of any respective desired shape, and can be respectively made of any suitable material, a wide variety of which are well-known and readily available. Representative examples of materials out of which the heat dissipating fins and/or the annular region can be made are extruded aluminum, die cast aluminum, liquid crystal polymer, polyphenylene sulfide (PPS), thermoset bulk molded compound or other composite materials, which provide excellent heat transfer properties, which would assist in dissipating heat generated by the light engine. In some embodiments, the heat dissipating fins are integral with the trim element and/or the annular region.
Any desired light diffuser can be employed, if desired, and persons skilled in the art are familiar with and have easy access to a variety of such diffusers. In some embodiments of the present inventive subject matter, a diffuser is mounted below the light engine housing, whereby light emitted from the light engine passes through the diffuser and is diffused prior to exiting the lighting device into the region that will be illuminated by the lighting device, e.g., into a room. Alternatively or additionally, the lighting devices according to the present inventive subject matter can include a reflective element. Any desired reflective element can be employed, and persons skilled in the art are familiar with and have easy access to a variety of such reflective elements. A representative example of a suitable material out of which the reflective element can be made is a material marketed by Furukawa (a Japanese corporation) under the trademark MCPET�. In some embodiments of the present inventive subject matter, a reflective element is shaped and is positioned so as to cover at least part of the internal surface of the sidewall of the trim element. In some embodiments of the present inventive subject matter, a diffuser is provided and is mounted below the light engine housing, and a reflective element is provided and is mounted so as to cover the internal surface of the sidewall of the trim element (and/or the lighting device housing) below the diffuser.
The lighting device housing can be any desired shape. A representative shape for the lighting device housing is hollow substantially cylindrical, e.g., as in conventional �can� light fixtures. Other representative shapes include hollow conical (or substantially conical), hollow frustoconical (or substantially frustoconical) and hollow semi-elliptical (or substantially semi-elliptical), or any shape which includes one or more portions which are individually selected from among hollow conical (or substantially conical), hollow frustoconical (or substantially frustoconical), hollow cylindrical (or substantially cylindrical) and hollow semi-elliptical (or substantially semi-elliptical).

FIGS. 1-4 depict a first embodiment of a lighting assembly in accordance with the present inventive subject matter. Referring to FIG. 1, there is shown a lighting assembly 10 which comprises a light engine assembly 11 and a room-side element 12 in contact with a portion of the light engine assembly 11. Referring to FIG. 2, the light engine assembly 11 comprises a trim element 13, a light engine housing 14 and a light engine 15. The trim element 13 defines a trim element internal space 16. The light engine housing 14 is positioned within the trim element internal space 16. The light engine housing 14 defines a light engine housing internal space 17. The light engine 15 is positioned within the light engine housing internal space 17 (and therefore is also within the trim element internal space 16) and comprises a plurality of LEDs 18. A thermal interface element 22 is positioned between the light engine housing 14 and the trim element 13 The trim element 13 comprises a flange portion 19 which extends farther from an axis of the trim element 13 than all other portions of the trim element 13, and a surface of the room-side element 12 (see FIG. 1) is in contact with the flange portion 19. As seen in FIGS. 2 and 3, the flange portion 19 extends in a plane which is substantially perpendicular to an axis of the trim element 13.
FIG. 13 depicts an alternative light engine assembly 131, which includes a trim element 133, a light engine housing 134 and a light engine 135. The trim element 133 defines a trim element internal space 136. The light engine housing 134 is positioned within the trim element internal space 136. The light engine housing 134 defines a light engine housing internal space 137. The light engine 135 is positioned within the light engine housing internal space 137 (and therefore is also within the trim element internal space 136) and comprises a plurality of LEDs 138. The light engine assembly 131 further includes a thermal interface element 139 positioned between and in contact with each of an external surface of the light engine housing 134 and an internal surface of the trim element 133. FIG. 13 also depicts a plurality of light engine housing fins 140, each of which is: (1) in contact with an external surface of the light engine housing 134 (and integral with the light engine housing 134), (2) in contact with an internal surface of the trim element 133, (3) outside of the light engine housing internal space 137, and (4) inside the trim element internal space 136.
