For example, the bulb can be evacuated and hermetically sealed to minimize heat transfer from the light emitting device. One or more reflective surfaces can be provided to reflect radiant energy from the light emitting device away from the electronics package. One or more insulating components can be positioned between the electronics package and the light emitting device. ## Claims ### Claim 1 A lamp assembly, comprising: a base; a housing positioned proximate to the base, the housing having an internal surface and defining an interior compartment; a bulb supported by the housing and defining an enclosed and evacuated space; a light emitting device positioned within the enclosed space of the bulb; and an electrical unit received into the interior compartment of the housing and located external to the evacuated space of the bulb, the electrical unit connected electrically with the light emitting device. ### Claim 2 (depends on 1) A lamp assembly as in claim 1, further comprising a reflective coating positioned along the internal surface of the housing and configured for reflecting energy from the light emitting device away from the electrical unit. ### Claim 3 (depends on 1) A lamp assembly as in claim 1, wherein the bulb has a base portion received into the interior compartment of the housing and the lamp assembly further comprises a reflective coating positioned on the base portion of the bulb and configured for reflecting energy from the light emitting device away from the electrical unit. ### Claim 4 (depends on 3) A lamp assembly as in claim 3, wherein the reflective coating on the base portion of the bulb does not extend outside of the housing. ### Claim 5 (depends on 3) A lamp assembly as in claim 3, wherein the reflective coating comprises a material that reflects infrared radiation created by the light emitting device. ### Claim 6 (depends on 3) A lamp assembly as in claim 3, wherein the reflective coating comprises one or more of aluminum, tin, aluminum oxide, tin dioxide, silver, boron nitride, polycarbonate, polyethylene, polyethylene terephthalate, or polytetrafluorethylene. ### Claim 7 (depends on 1) A lamp assembly as in claim 1, wherein the evacuated space is at a pressure in the range of about 100 mbar or less. ### Claim 8 (depends on 1) A lamp assembly as in claim 1, wherein the bulb is hermetically sealed. ### Claim 9 (depends on 1) A lamp assembly as in claim 1, further comprising a thermal shield positioned between the light emitting device and the electrical unit and configured for insulating the electrical unit from the light emitting device. ### Claim 10 (depends on 1) A lamp assembly as in claim 1, wherein the light emitting device comprises a halogen lamp, incandescent lamp, a discharge lamp, or a high intensity discharge lamp. ### Claim 11 (depends on 1) A lamp assembly as in claim 1, wherein the electrical unit comprises an electrical transformer. ### Claim 12 A thermally protected lamp assembly, comprising: a housing defining an interior compartment; a bulb having a base portion and a body portion, the bulb defining an enclosed volume that is evacuated, the base portion of the bulb received within the interior compartment of the housing; an electronics package received into the interior compartment of the housing and located outside of the enclosed volume of the bulb; and a light emitting device positioned within the enclosed volume of the bulb and connected with the electronics package. ### Claim 13 (depends on 12) A thermally protected lamp assembly as in claim 12, further comprising a reflective coating positioned on the base portion of the bulb and configured for reflecting radiant energy from said light emitting device. ### Claim 14 (depends on 13) A thermally protected lamp assembly as in claim 13, wherein the reflective coating is located on an interior surface of the bulb and is shaped to reflect radiant energy from the light emitting device away from the electronics package. ### Claim 15 (depends on 13) A thermally protected lamp assembly as in claim 13, further comprising an insulating element located between the bulb and the light emitting device so as to thermally protect the electronics package from energy transmitted by said light emitting device. ### Claim 16 (depends on 12) A thermally protected lamp assembly as in claim 12, wherein the housing has an interior surface, and further comprising a reflective coating located on the interior surface of the housing and configured for reflecting radiant energy from the light emitting device. ### Claim 17 (depends on 12) A thermally protected lamp assembly as in claim 12, wherein the housing comprises a reflective polymer. ### Claim 18 A lamp assembly, comprising: a bulb defining an enclosed and evacuated space; a housing positioned proximate to the bulb, the housing having an interior compartment; a base connected with the housing; a lighting emitting device positioned within the bulb so as to project light through the enclosed and evacuated space; and an electrical unit received into the interior compartment of the housing and located external to the enclosed and evacuated space of the bulb, the electrical unit connected electrically with the light emitting device. ### Claim 19 (depends on 18) A lamp assembly as in claim 18, wherein the bulb defines an internal cavity into which at least a portion of the housing is received. ### Claim 20 (depends on 18) A lamp assembly as in claim 18, further comprising a thermal shield positioned between the bulb and the electrical unit.
