摘要： An LED (light emitting diode) includes a light emitting chip and a lens above the chip. The lens includes a base and a convex curved circumferential surface extending upwardly from a periphery of the base toward a center of the lens. An acute angle formed between a light ray generated by the chip and projecting on a point of the convex curved circumferential surface and a main axis of the lens extending vertically from a center of the chip is smaller than that formed between the normal for the point of the convex curved circumferential surface and the main axis of the lens so that light generated by the chip is converged by the lens. A light-emission angle of the LED at 10% of a peak light intensity of the LED is ranged between 60-75 degrees from the main axis.

摘要： An LED device comprises an LED assembly and a power supply circuit. The power supply circuit includes an AC circuit connecting to the power source, a DC circuit coupling with the AC circuit, a driving circuit and a snubber circuit connected with each other and located between the DC circuit and the LED assembly. The locations of the driving circuit and the snubber circuit in the power supply circuit are exchangeable, i.e., the driving circuit being connected to the DC circuit and the snubber circuit being connected to the LED assembly, or the driving circuit being connected to the LED assembly and the snubber circuit being connected to the DC circuit. The snubber circuit is used for extending a time period for a voltage value of a DC initially applied to the LED assembly to increase from zero to a predetermined value.

摘要： An electric fan includes a fan base (10), a bearing (40) and a rotor assembly (20). The fan base forms a central tube (11) receiving the bearing therein. The rotor assembly includes a fan hub (22), and a pivot axle (23) joined to the fan hub. The pivot axle pivotably extends into the bearing. A sealing lid (60) is screwedly mounted on a bottom opening of the central tube to prevent lubricant oil contained in the central tube from leaking. The sealing lid abuts against a bottom of the bearing to prevent the bearing from deflection.
