Patent number: 9562652Abstract: A low profile LED lamp bulb with high efficient heat dissipation is disclosed. Each of the lead frame unit has a top-down tapered metal section on bottom end adaptive for being bent inwards to form a lead frame bottom cup suitable for fitting in the low profile LED lamp. A modification embodiment is that a heat sink independent from electrode is attached to a backside of the lead frame with nonconductive adhesive material, heat and electricity are independent from with each other, so that no interference between heat and electricity, and heat can be dissipated mainly from the heat sink.Type: GrantFiled: March 16, 2016Date of Patent: February 7, 2017Assignee: UNILED LIGHTING TW., INC.Inventors: Po-Cheng Yang, Ming-Yao Lin, Ming-Te Lin

Patent number: 9303821Abstract: An air-cooled lamp bulb includes a central tube and a circular light wall. The circular light wall is formed by a plurality of light units surrounding the central tube and emitting light beams in a direction away from the central tube. A top frame supports the circular light wall on top. A top opening is formed in the top frame. A bottom gap is formed between a bottom of the central tube and a bottom of the circular light wall. An air passage is formed between the central tube and the circular light wall. The air passage connects the top opening and the bottom gap for allowing air flow through the air-cooled lamp bulb.Type: GrantFiled: June 17, 2013Date of Patent: April 5, 2016Assignee: UNILED LIGHTING TW., INC.Inventors: Ming-Te Lin, Ming-Yao Lin, Heng Qiu
