  • Patent number: 7994516
    Abstract: The present invention discloses an LED module comprising: a waterproof enclosure; an LED accommodated in the waterproof enclosure; a wire for coupling the LED module with other LED modules and a driver; and a radiating unit set in the bottom of the waterproof enclosure and exposed to the external environment. The invention further provides an LED chain comprising the above said LED module and a driver coupled with the LED module. The LED chain according to the invention may have a high waterproof level, for example, IP65. The heat generated during the operation of the high power LED module may be transmitted to the external environment in time via a heat sink set on the LED module, thereby effective thermal management for the LED module and a long service life of the LED module may be obtained. Moreover, the finish surface of the driver may be made handsome by encapsulating the driver through the low pressure molding.

  • Patent number: 7830094
    Abstract: A driver arrangement for LED light sources includes a transformer having primary and secondary winding connections. A first electronic switch (SW1) controls current flow through the primary winding, and a sensing resistor is coupled to the primary winding to produce a current sensing signal. A second electronic switch (SW2) is sensitive to the sensing signal to switch off SW1 as current flow through the primary winding reaches a given threshold. SW1 is thus alternatively turned-on and off in alternating turn-on and switch-off phases to power the LED light source via the secondary winding. SW1 is a field effect transistor, preferably a MOSFET. The transformer is SELV-rated. The sensing resistor may be a variable resistor to adjust the duration of the on/off phases to permit controlled dimming.
