摘要： An LED unit includes an LED having an optical axis and a lens mounted on the LED. The lens includes an incidence surface, an emission surface, and a light-reflecting face between the incidence surface and the emission surface. The light-reflecting face has a diameter gradually increasing from a bottom towards a top of the lens. The incidence surface includes a first incidence surface and a second incidence surface extending downwardly from a circumference of the first incidence surface and protruding inwardly towards the LED. Light emitted from the LED with a large angle is refracted by the second incidence surface into substantially parallel beams in one side of a cross-section of the lens through the optical axis of the LED, and the parallel beams are sequentially reflected by the light-reflecting face and refracted by the emission surface out of the lens in substantially parallel beams.

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： A lamp includes a bracket having a cover, a lamp body fixed to the bracket by a shaft, a heating device and a pressure switch. The lamp body includes first and second portions at opposite sides of the shaft. The heating device is mounted at the first portion of the lamp body and the cover. The pressure switch is mounted to the cover and engages with a top of the second portion. When a weight of the snow/ice accumulated on the first portion of the lamp body is beyond a set value, the pressure switch controls the heating device to be switched on to melt the snow/ice; when the weight of the snow/ice accumulated on the lamp body decreases to be less than the set value, the pressure switch controls the heating device to be switched off.

摘要： An LED illumination system includes an LED lamp, a voltage stabilizing circuit and a control circuit. The LED lamp includes an LED string which has a plurality of LEDs connected in series. The voltage stabilizing circuit connects the LED lamp for supplying an electric current to the LED string. The control circuit includes an MCU and a MOSFET connected between the MCU and the LED string. The MCU detects the electric current flowing through the LED string and outputs a PWM signal which has a frequency within a range from 60 Hz to 500 Hz to the MOSFET. The MOSFET receives the PWM signal from the MCU and turns on and off repeatedly under a control of the PWM signal, to make a flicker frequency of the LEDs of the LED string be within a predetermined range.

摘要： An LED illumination system includes a control circuit having a timing unit, a control unit, a PWM signal generating unit and a micro-programmed control unit (MCU). The timing unit divides an operating period of an LED lamp into different time segments, and outputs clock signals. The control unit outputs different controlling signals corresponding to the clock signals to the PWM signal generating unit, which in turn generates different PWM signals with different duty cycles. A constant current circuit electrically connects the control circuit and outputs different electric currents to make the LED lamp emit light having different light intensities at the different time segments. The MCU is at an outside of the LED lamp and sets a program to control the timing unit, the control unit and the PWM signal generating unit.

Each LED comprises an LED die, a base supporting the LED die thereon and thermally contacting the substrate to take heat generated by the LED die to the substrate, a pair of leads electrically connecting the LED die to input a current to the LED die, and an encapsulant enveloping the LED die. The pair of leads hover above the substrate to separate an electrical route of the LED assembly from a heat conducting pathway thereof. Furthermore, each LED has a plurality of legs extending radially from the base thereof to fit in the base of an adjacent LED, to thereby engagingly lock with the adjacent LED.
