| 20100033237 | Multi-functional drMOS - A DrMOS combines a high side power MOSFET, a low side power MOSFET and a driver circuit for driving the power MOSFETs with current balance and thermal balance mechanism and variable phase control circuit on a single chip. | 02-11-2010 |
| 20110006746 | SOFT-START CIRCUIT AND METHOD FOR A SWITCHING REGULATOR - A soft-start circuit for a switching regulator includes a signal generator and a scaling circuit coupled to the signal generator. During soft-start, the signal generator provides a ramp signal for the switching regulator such that the output voltage of the switching regulator changes from a residual voltage toward a target level. When soft-start is triggered, the scaling circuit provides a scaling voltage depending on the residual voltage, to shift the level of the ramp signal and consequently shorten the soft-start time of the switching regulator. | 01-13-2011 |

| 20090179588 | Outdoor lighting device - An outdoor lighting device includes a housing, at least one power supply device and at least one arrayed lighting unit. The housing has a surface forming at least one reflection zone and he reflection zone includes a lens. The power supply device is arranged inside the housing and has a grounding terminal connected to the housing. The power supply device receives and converts an alternate current power into an output of direct current power. The arrayed lighting unit includes plural arrays of lighting elements and a light-transmitting protection layer. The arrayed lighting unit is arranged inside the housing at a location corresponding to the lens and is connected to the power supply device, whereby the power supply device provides the arrayed lighting unit with the direct current power to energize the arrayed lighting unit to give off light that is reflected by the reflection zone. As such, an outdoor lighting device containing therein an arrayed lighting unit and an internal built-in power supply device is formed. | 07-16-2009 |
| 20100149810 | Mounting structure of component of lighting device and method thereof - Disclosed is a structure for mounting a component to a lighting device, including at least one lighting-device base, at least one metal film, and a lighting array chip. The lighting-device base has a surface to which a first layer of metal bonding agent is applied. The metal film has a surface attached to the first metal bonding agent layer on the surface of the lighting-device base. The lighting array chip has a bottom surface to which a second layer of metal bonding agent is applied. The second metal bonding agent layer is further attached to an opposite surface of the metal film so as to securely mount the lighting array chip to the surface of the lighting-device base. A mounting method is also provided, including the steps of applying a metal bonding agent to a surface of a lighting-device base; connecting the lighting-device base to a positive electrode of a power source; connecting a metal film to a negative electrode of the power source; applying a metal bonding agent to a lighting array chip; bonding the lighting array chip to the metal film; and hot-pressing to bond the lighting array chip to the lighting-device base, so that the lighting array chip is securely mounted to the surface of the lighting-device base by means of thermal fusion caused between the negative and positive polarities of the power source applied to the metal film and the lighting-device base. | 06-17-2010 |
