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.
Claims20
A light emitting device comprising:
- 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 comprise at least one light emitting diode (LED);
- a driving module configured to supply 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 configured to connect first to n-th light source groups provided in one of the plurality of light emitting modules to first to n-th light source groups provided in another light emitting module in parallel in a detachable manner, respectively.
A light emitting device comprising:
- a plurality of light emitting modules each comprising first to n-th light source groups, n being an integer greater than two, and physically separated from one another;
- a driving module configured to supply 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 configured to connect the first to n-th light source groups provided in each of the plurality of light emitting modules to first to n-th light source groups provided in an adjacent light emitting module in parallel in a detachable manner, respectively.
A light emitting device comprising:
- at least one light emitting module comprising a plurality of light source groups, each comprising at least one light source;
- and
- a driving module configured to control turn-on and turn-off of the light source groups based on a level of power input to the driving module,
- wherein the driving module is configured to turn on a different number of the light source groups as the level of the input power is changed.
