Embodiment Construction

[0025] Reference will now be made in more detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and specification to refer to the same or like parts.

[0026] The structure of embodiments of the present invention has improved power efficiency because the current regulator 30 is used to drive power.

[0027] refer to figure 1 , the LED lighting device according to one embodiment of the present invention includes a power source unit 10 , a transformer T, a sensor board 20 , and a current regulator 30 .

[0028] The power source unit 10 is configured to perform full-wave rectification on AC power and output the result of the full-wave rectification as a rectified voltage. That is, the power source unit 10 has a structure in which the power source 12, the rectification circuit 14, and the capacitor C1 are connected in parallel.

Abstract

The present invention discloses an LED lighting apparatus. The LED lighting apparatus includes a converter for transforming rectified voltage in accordance with a switching operation according to a driving pulse and outputting the transformed voltage, a current regulator for generating the driving pulse having a pulse width varied in response to a control signal and the amount of current of the converter and switching the operation of the converter using the generated driving pulse, and a peripheral circuit module for providing the control signal for controlling the dimming of an LED lighting.

Description

technical field [0001] The present invention relates to a light emitting diode (hereinafter "LED") lighting device, and more particularly to an LED lighting device with improved power efficiency, a current regulator for the LED lighting device, and a current adjustment method for the LED lighting device. Background technique [0002] In recent lighting equipment, LEDs having a long lifespan, low power consumption, and high brightness are used as lighting lamps instead of incandescent lamps and fluorescent lamps. [0003] For example, lighting equipment may include security lights and street lights. LED lighting equipment using LED lighting has also been developed and commercialized as a security light or a street light. [0004] Typically, conventional LED lighting equipment is implemented using a switched-mode power supply (hereinafter referred to as SMPS) module, which uses a commercial AC power source. [0005] An example of a conventional LED lighting device configured...
