Embodiment Construction

[0045] Please refer to figure 1 , which is a functional block diagram of a known LED lighting module 10 . The LED lighting module 10 includes a power supply 12 , a driving circuit 13 and an LED load circuit 20 , wherein the driving circuit 13 includes a rectifying and filtering circuit 14 , a power factor correction circuit 16 , and a constant voltage / current driving circuit 18 . In the LED lighting module 10 , the power source 12 can be, for example, a commercial power, and the commercial power is generally 110 volts of alternating current. The rectifying and filtering circuit 14 rectifies and filters the AC voltage output by the power supply circuit 12 into a noise-free DC voltage. The power factor correction circuit 16 receives the DC voltage and adjusts the power factor so that the current waveform follows the voltage waveform. The constant voltage / constant current driving circuit 18 is used to control the voltage variation of the DC voltage or the current variation of t...

Abstract

The invention discloses a light emitting diode lighting module and a lighting device used thereby. The light emitting diode lighting module at least comprises a light emitting diode load circuit and a driving circuit. The light emitting diode load circuit consists of light emitting diode cascaded groups which are electrically connected in parallel, and each light emitting diode cascaded group at least comprises a plurality of light emitting diodes which are electrically connected in series, wherein each light emitting diode is provided with a preset working voltage range. The driving circuit is used for providing a variable voltage to drive the light emitting diode load circuit, wherein the variable voltage is provided with a voltage varying range which is beyond the preset working voltage range of the light emitting diode. When light emitting diode load circuit works, the light emitting diode is operated within an allocated voltage varying range which is within the preset working voltage range.

Description

technical field [0001] The present invention relates to a light-emitting diode (LED) lighting module and its applied lighting device, in particular to an LED lighting module that does not need a constant voltage or constant current circuit and its applied lighting device. Background technique [0002] Illumination devices have been widely used in human life, and can be seen in various buildings, vehicles or decorations. For human beings, a lighting device is not merely a tool for providing lighting, it has a great influence on human life. [0003] Currently common lighting devices include incandescent lamps, fluorescent lamps, light emitting diode (LED) lamps and the like. Traditional incandescent lamps energize tungsten filaments to generate high-temperature light for lighting. However, this lighting method is very power-hungry, making incandescent lamps gradually replaced by fluorescent lamps. [0004] Fluorescent lamps emit electrons by applying a high voltage to the e...
