  • Patent number: 9640741
    Abstract: Provided is a concentrating lens of a light emitting diode lamp comprising a lens body. The lens body comprises a top portion, a bottom portion opposite the top portion, a light output surface positioned on the top portion, an optical surface formed concavely on the light output surface, and a light input surface concavely formed on the bottom portion and towards the top portion. The light input surface is disposed on a same axis with the optical surface. The light input surface comprises a light input side plane and a light input concave plane connected with the light input side plane. The concentrating lens is capable of distributing the light of LED to positions on each of the side walls of a light box close to and distal from the LED, and allowing the light emitted from the LED to lighten the light box uniformly.

  • 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: 7310074
    Abstract: A DMX512 signal source distributor and a loader for a plurality of LED controllers can control LED devices such as an LED board. The DMX512 signal source distributor includes a UART, an MCU connecting to a memory, and a DMX512 encoder chip connecting to a memory. The UART is connected with a personal computer and the MCU, and the UART also can provide a wireless transmission function. The DMX512 encoder chip is further connected to several differential drivers. A loader includes a UART, a MCU connecting to a memory, a keyboard, and an LCM. The signal controllers are controlled by the DMX512 signal source distributor and the loader. The LED controllers can be modulized, which not only can work alone, but also can be combined into a complex system.
