Abstract

A light emitting device includes: a plurality of light emitting modules each provided with a circuit board, and first to n-th light source groups disposed on the circuit board, n being an integer greater than two, wherein the first to n-th light source groups each include at least one light emitting diode (LED); a driving module supplying driving power to the plurality of light emitting modules, and determine a number of light source groups operating in each of the plurality of light emitting modules based on a level of the driving power; and a module connection unit connecting first to n-th light source groups provided in one of the plurality of light emitting modules and first to n-th light source groups provided in another light emitting module in parallel in a detachable manner, respectively.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0142897 filed with the Korean Intellectual Property Office on October 21, 2014, the entire disclosure of which is incorporated herein by reference. technical field [0003] Apparatuses and methods consistent with exemplary embodiments relate to a light emitting device. Background technique [0004] Various advantages of light-emitting diodes (LEDs) such as longer lifetime, low power consumption, excellent initial drive performance, and high level of shock resistance compared to filament-based light-emitting devices have led to continued growth in the demand for light-emitting diodes . On the other hand, since the LED has a characteristic of being driven by direct current (DC) power, a rectification circuit is generally provided for a light emitting device using the LED. However, such a rectifier circuit will complicate the configuration of th...
