Publication number: 20130128578Abstract: A lamp includes a supporting body and a lamp body. The supporting body is fixed to a support such as a ceiling. The supporting body defines a plurality of apertures each including a hole and a slot. The slot has a width less than a diameter of the hole. The lamp body includes a housing, a heat sink, a light source and a cover. The housing forms a plurality of protrusions each including a pole and a head. The head has a diameter larger than a width of the slot. The protrusions extend through the holes of the apertures and then are rotated into the slots, whereby the heads are located above the slots and engage with the supporting body. Thus, the lamp is suspended from the support. A resilient member is provided between the housing and the supporting body.Type: ApplicationFiled: April 27, 2012Publication date: May 23, 2013Applicants: FOXCONN TECHNOLOGY CO., LTD., CHAMP TECH OPTICAL (FOSHAN) CORPORATIONInventors: GUANG YU, QIAN XIANG

Patent number: 8430528Abstract: An LED bulb includes a connector, a heat sink disposed on the connector, an LED module, and an envelope secured to the heat sink and covering the LED module. The heat sink includes a tubular body defining a central through hole, a plurality of fins, and a supporting body located in the tubular body and interconnecting inner edges of the fins. The LED module is attached on the supporting body of the heat sink. A fan is received in the tubular body. When the LED bulb is at work, the fan generates an airflow which flows from an outer environment through the tubular body, the through hole, the LED module, the fins and finally the tubular body to return to the outer environment, thereby to effectively take away the heat generated by the LED module.Type: GrantFiled: March 9, 2011Date of Patent: April 30, 2013Assignees: Fu Zhun Precision Industry (Shen Zhen) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Guang Yu, Qian Xiang
