    摘要： An LED unit (10) includes an LED (20) and a lens (30) disposed on the LED. The lens includes a square body (32) and a frustum-shaped body (34) formed downwardly from the square body, wherein a tapered side face (342) of the frustum-shaped body is coated with a reflective film. The LED includes a lens (26) that has a planar top face (28) directly contacting with a planar, circular bottom face (340) of the frustum-shaped body of the lens; thus light emitted from an LED chip (23) in the LED can pass through the lens of the LED and the lens without a total internal reflection occurring at an interface between the lens of the LED and the lens. Accordingly, a high bright light is obtained since nearly all of the light can be transmitted out of the LED unit.

    摘要： An LED lamp includes a hollow, prism-shaped heat sink (30), a plurality of LED modules (20) attached on sidewalls (320) of the heat sink, a cover (40) mounted on a top of the heat sink, a lampshade (10) secured to a bottom of the heat sink, and a fan (50) fixed on the top of the heat sink and through the cover. A plurality of fins (340) extends inwardly from inner faces of the heat sink to cooperatively define two crossed slots in the heat sink. When the fan is in operation, an airflow produced by the fan flows through the fins from the top through the bottom of the heat sink, thereby dissipating heat absorbed by the heat sink from the LED modules rapidly and efficiently.

    摘要： An LED lamp includes a heat absorbing member having a hollow, cylindrical configuration, a lamp base, a plurality of LED modules and a heat sink. The heat absorbing member defines a through hole therein. The heat sink is secured to a top portion of the heat absorbing member. The lamp base is secured to a bottom portion of the heat absorbing member. The LED modules are mounted on an outer sidewall of the heat absorbing member, and each of the LED modules includes a printed circuit board and a plurality of LEDs mounted on the printed circuit board. Each of the heat pipes has an evaporating portion received in an inner sidewall of the heat absorbing member and a condensing portion connecting with the heat sink. The condensing portions of the heat pipes are radially arranged on the heat sink, radiating outwardly from a central point of the heat sink.

    摘要： A fully automatic, computationally efficient segmentation method of video employing sequential clustering of sparse image features. Both edge and corner features of a video scene are employed to capture an outline of foreground objects and the feature clustering is built on motion models which work on any type of object and moving/static camera in which two motion layers are assumed due to camera and/or foreground and the depth difference between the foreground and background. Sequential linear regression is applied to the sequences and the instantaneous replacements of image features in order to compute affine motion parameters for foreground and background layers and consider temporal smoothness simultaneously. The Foreground layer is then extracted based upon sparse feature clustering which is time efficient and refined incrementally using Kalman filtering.
