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.

摘要： Disclosed herein is a light source device using light-emitting diodes (LEDs). Specifically, a two-sided, surface light source device is implemented with point light sources such as LEDs in a simple configuration, such that even surface light is emitted. The two-sided, surface light source device includes: a substrate on which light-emitting diodes (LEDs) are disposed as a light source; and a two-sided diffusion unit having a plate-like shape with a front side face, a back side face, and a light-receiving face that is perpendicular to the front side face and the back side face and faces the substrate. Light emitted from the light source is diffused in the diffusion unit and exits through the front side face and the back side face.
