Patent number: 8294339Abstract: The present invention relates to a LED lamp and a heat sink thereof having a wound heat pipe. The LED lamp includes the heat sink, a LED module and a lamp base electrically connected to the LED module. The heat sink includes a heat-conducting base, a heat-dissipating fin set and a wound heat pipe. The heat-dissipating fin set includes a plurality of heat-dissipating fins arranged at the outer periphery of the heat-conducting base. The heat-dissipating fins form an accommodating space. The wound heat pipe includes an evaporating section brought into thermal contact with the heat-conducting base and a condensing section brought into thermal contact with the heat-dissipating fins. The LED module abuts against the heat-conducting base and the evaporating section. By this structure, the heat-conducting path is shortened, the heat-conducting speed is accelerated, and the heat is rapidly and uniformly distributed to the heat-dissipating fins to improve the heat-dissipating efficiency.Type: GrantFiled: June 22, 2010Date of Patent: October 23, 2012Assignees: CPumate Inc., Golden Sun News Techniques Co., Ltd.Inventors: Kuo-Len Lin, Chen-Hsiang Lin, Chih-Hung Cheng

Patent number: 8287144Abstract: The present invention relates to LED bar modules where the LED groups are placed at a pixel board. The present invention further concerns a method for calibration of LEDs. It is the object of the invention to achieve a highly efficient LED bar for generating a bar of light. A further object of the invention is to store calibration data for each LED both electrically and mechanically close to the actual LED. Preferably, the main printed circuit is placed inside a heat conductive tube, where the pixel board is placed outside the heat conductive tube in a longitudinal recess, where the main printed circuit is placed inside an isolation cover. Hereby, it is achieved that the LEDs are placed on the outside of the tube in a way where heat generated from the LEDs is conducted downwards to the tube. Inside the tube, the rest of the power electronics and also the light controlling electronics are placed.Type: GrantFiled: September 5, 2008Date of Patent: October 16, 2012Assignee: Martin Professional A/SInventors: Allan Pedersen, Xia Chen, Guohui Li, Chen Liang
