  • Publication number: 20130294078
    Abstract: The invention relates to a modular LED illuminating device that includes a case, multiple LED units and a power wire. The case has a front cover and a rear cover. Multiple holding holes are formed through the front cover, and a wire groove is formed on the rear cover. The multiple LED units are held by the multiple holding holes. The power wire is partially mounted in the wire groove and electrically connected to the multiple LED units. Compared with conventional fluorescent lamps, the modular LED illuminating device has long lifetime and saves more energy.

  • Publication number: 20130294070
    Abstract: A high bay light has a lamp holder, a light module, a plurality of cooling modules and a lamp cover. The lamp holder includes a frame. The frame has a plurality of connecting pieces extending radially therefrom. The light module is mounted on the lamp holder and includes a printed circuit board and at least one LED. The cooling modules are mounted on the printed circuit board and each cooling module includes a heat pipe and a cooling component. The lamp cover covers the cooling modules and includes an open bottom, an interior and a top hole. The open bottom and the top hole communicate with the interior. The connecting pieces of the frame are secured to the lamp cover so as to form a plurality of bottom holes between adjacent connecting pieces. With the above-mentioned structure, the high bay light can provide improved heat dissipation.

  • Publication number: 20130235575
    Abstract: An LED light module has a mounting board and multiple LED lights mounted securely on the mounting board. Each LED light has a casing, a lighting module and two resilient sheets. The lighting module is mounted in the casing. The resilient sheets are mounted on an outside wall of the casing and abut an annular edge around a mounting hole of the mounting board. The LED lights are mounted securely on the mounting board by the resilient force of the resilient sheets, so the user only has to push the LED light to resist the slightly resilient force, and the LED light can be disassembled from the mounting board. Thus, any individual LED light can be easily disassembled.

  • Patent number: 8459846
    Abstract: A heat-dissipating downlight lamp holder has a lamp holding unit, multiple fins and a bottom board. The fins are mounted on a periphery of the lamp holding unit to effectively dissipate heat of a light bulb mounted in the lamp holding unit out of the lamp holder. The bottom board located underneath the lamp holding unit has multiple air inlets formed through the bottom board to let cold air under the lamp holder enter the lamp holding unit through the air inlets. By convection, heat dissipated from the fins is carried away from the downlight, thereby effectively reducing heat accumulated by the light bulb and preventing the light bulb from being damaged by high heat.

  • Publication number: 20120098399
    Abstract: An LED lamp having a heat-dissipating mechanism has a top casing, a heat-conducting tube and a bottom casing. The top casing has a foundation board, a lamp holder and multiple fins. The foundation board has a first tube guide formed around and protruding downwardly from a perimeter of the foundation board and is made of a metal material. The lamp holder is hollow and centrally mounted through the top casing, and has a second tube guide formed on a bottom thereof. The fins are radially formed on a top of the foundation board and around the lamp holder. The heat-conducting tube is mounted against one side of the first tube guide and within the second tube guide. The bottom casing is securely combined with the top casing. Besides the fins, the heat-conducting tube enlarges the contact area with the top casing, thereby enhancing the heat-dissipating efficiency.

  • Patent number: 8093790
    Abstract: A waterproof LED lamp has a lamp housing, a top lid, a base and a power contact assembly. The lamp housing has an LED circuit board mounted therein. The top lid is mounted on the lamp housing and above the LED circuit board. A lid seal ring is mounted between the top lid and the lamp housing to prevent moisture from entering the lamp housing. The base has multiple LED modules mounted therein and has a base seal ring mounted between the lamp housing and the base to prevent moisture from entering the lamp housing. A heat-conducting tube is mounted inside the lamp housing. A waterproof insulation layer sheathed on the heat-conducting tube and a gasket mounted between the base and the power contact assembly prevent moisture entering the lamp housing through the power contact assembly and the base. Accordingly, an overall waterproof effect can be achieved.

  • Patent number: 6648498
    Abstract: A light string is composed of multiple light emitting units. Each light emitting unit utilizes multiple LEDs as the light emitting source to generate various light colors for enriching visual effects. Further, the light string is able to adhere to form any particular configuration as an attractive advertising device. By using the LEDs as the light source, power consumed by the light string is very low and operators of the light string are not exposed to high voltages.
