    摘要: An illumination system includes a power supply unit; and a light emitting apparatus driven by power supplied from the power supply unit. The light emitting apparatus includes: a first light emitting portion and a second light emitting portion configured to be independently driven to emit output light; and a controller configured to control a color temperature or a luminous flux of the output light by controlling operations of the first and second light emitting portions. The controller is configured to control an output color temperature of the output light according to color temperature control data for controlling an output color temperature of the second light emitting portion or control a luminous flux of the output light according to luminous flux control data for controlling an output luminous flux of the first light emitting portion.

    摘要: Disclosed is an improved light-emitting device for an AC power operation. A conventional light emitting device employs an AC light-emitting diode having arrays of light emitting cells connected in reverse parallel. The arrays in the prior art alternately repeat on/off in response to a phase change of an AC power source, resulting in short light emission time during a ½ cycle and the occurrence of a flicker effect. An AC light-emitting device according to the present invention employs a variety of means by which light emission time is prolonged during a ½ cycle in response to a phase change of an AC power source and a flicker effect can be reduced. For example, the means may be switching blocks respectively connected to nodes between the light emitting cells, switching blocks connected to a plurality of arrays, or a delay phosphor. Further, there is provided an AC light-emitting device, wherein a plurality of arrays having the different numbers of light emitting cells are employed to increase light emission time and to reduce a flicker effect.
