1. An air cooled horticulture lamp fixture 1 for growing plants in confined indoor growing spaces, comprising:
a housing 200 having an open bottom 205 circumscribed by a housing edge 210, a first duct 235 being substantially aligned to a second duct 245, and a housing interior 220; a reflector 100 captured within the housing interior 220, the reflector 100 having at least one aperture therein, a reflector interior side 101, a reflector exterior side 102, a reflector top 104, and an open bottom 106 circumscribed by a reflector lip 103, the reflector lip 103 located adjacent to the housing edge 210 defining at least one cooling chamber 300 in the space between the reflector exterior side 102 and the housing interior 220, the cooling chamber 300 being in air communication with the first duct 235 and the second duct 245; at least one socket, said socket disposed to fill said aperture and capable of electrically connecting an end of a lamp bulb 2 so that said lamp bulb 2 is oriented substantially parallel to a plane formed by said housing edge 210 as located within the reflector interior side 101; a cooling air stream 310 disposed through the cooling chamber 300 between the first duct 235 and the second duct 245; a glass sheet 30 and gasket 31 disposed at least proximate to the reflector lip 103 to seal the reflector interior side 101 from the confined growing space; at least one flow disruptor 160 disposed within the cooling air stream 310, the flow disruptor 160 being constructed and arranged to disturb laminar flow of the cooling air stream 310 creating local turbulence within the cooling chamber 300 whereby enhancing convective heat transfer from the reflector 100 into the cooling air stream 310. |
