20120212942 | INDUSTRIAL LED LAMP - An industrial LED lamp comprises: a housing having at least one compartment and a built-in power supply, and the built-in power supply having a first connecting portion; at least one LED lamp, disposed in the compartment, and having a second connecting portion electrically coupled to the first connecting portion for driving the LED lamp to light up; and a stand, disposed in the compartment, and having a platform at an end of the stand, and a plurality of support legs at the other end of the stand. When use, the LED lamp and the stand are removed from the housing and then connected, and the LED lamp is electrically coupled to the built-in power supply, so that the LED lamp improves the convenience of mobility, installation, use and storage and requires no external electric power for its use. | 08-23-2012 |
20120081000 | LED ENCAPSULATION PROCESS AND SHIELD STRUCTURE MADE THEREBY - The present invention discloses an LED encapsulation process and a shield structure made thereby. Firstly, a first encapsulation layer is provided, phosphor powder is uniformly disposed on a surface of the first encapsulation layer, and a second encapsulation layer is disposed on the phosphor powder to fully cover the first encapsulation layer so that the phosphor powder is sandwiched between the two encapsulation layers to ensure its arrangement position. Finally, the aforementioned members are heated and stamped to form one piece which is cut into a required shield shape. | 04-05-2012 |
20110169392 | LED PROJECTION LAMP - A light emitting diode (LED) projection lamp includes a lamp body and a plurality of LEDs. The lamp body includes an inverted conical shaped external cover, an electric contact base formed at the tip of the external cover, and a plurality of protrusions arranged on an internal wall of the external cover with a circular distribution, and each protrusion has at least one fixing surface. The LEDs are installed separately on each fixing surface, and an inclination is formed between lights emitted by the LEDs and a projection plane for reducing reflective lights, and the LEDs are electrically coupled to the electric contact base, such that heat produced by using the LEDs is conducted directly to the external cover for its dissipation to improve the heat dissipating efficiency and lifespan of the lamp, and the angular arrangement of the LEDs also improves the saturation and reflection of the light. | 07-14-2011 |
20100277891 | LED CASING STRUCTURE - A light emitting diode LED casing structure, particularly to an LED casing structure having two or more layers, includes a phosphor distributed uniformly between plastic film layers in an LED casing, such that the phosphor in the LED casing will not be drifted and sunk easily during the manufacturing process of an LED. | 11-04-2010 |
20100264439 | LED PACKAGE STRUCTURE - A light emitting diode (LED) package structure includes a substrate having a chip disposal area and a recession, a chip installed in the chip disposal area, a silicon connecting element installed at the recession, and a silicon lens disposed at a position corresponding to the recession and coupled to the silicon connecting element, such that the silicon connecting element in the recession can assure the silicon lens to be secured onto the substrate to prevent the silicon lens from falling out. | 10-21-2010 |
