Alternating current-driven light emitting element lighting apparatus

#Field

#Exemplary embodiments of the present disclosure relate to a lighting apparatus using a dimmable alternating current-driven light emitting diode (LED), and more particularly, to an alternating current (AC)-driven LED lighting apparatus which allows dimming control through phase cut control and exhibits idealistic and stable variation of a dimming level over an entire interval of the dimming level using a triode for alternating current (TRIAC) dimmer. In addition, exemplary embodiments of the present disclosure relate to an AC-driven LED lighting apparatus which can improve compatibility of the TRIAC dimmer.

#Discussion of the Background

#The accompanying drawings, which are included to provide a further understanding of the inventive concept, and are incorporated in and constitute a part of this specification, illustrate exemplary embodiments of the inventive concepts, and, together with the description, serve to explain principles of the inventive concepts.

#FIG. 1 is a block diagram of an AC-driven LED lighting apparatus according to one exemplary embodiment of the present disclosure.

#FIG. 2 is a flowchart of a driving method of the AC-driven LED lighting apparatus according to the exemplary embodiment of the present disclosure.

#In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments. It is apparent, however, that various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring various exemplary embodiments.

#In the accompanying figures, the size and relative sizes of layers, films, panels, regions, etc., may be exaggerated for clarity and descriptive purposes. Also, like reference numerals denote like elements.

#When an element or layer is referred to as being “on,” “connected to,” or “coupled to” another element or layer, it may be directly on, connected to, or coupled to the other element or layer or intervening elements or layers may be present. When, however, an element or layer is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. For the purposes of this disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” may be construed as X only, Y only, Z only, or any combination of two or more of X, Y, and Z, such as, for instance, XYZ, XYY, YZ, and ZZ. Like numbers refer to like elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
