    Abstract: 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 daring 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.

    Abstract: A mobile disinfector using UV LEDs can include: a case forming an exterior structure of the disinfector; a cover including two parts coupled to respective sides of the case and including openings formed on the cover; and LED units exposed to outside through the openings formed on the cover. Since the cover is coupled to the case such that an angle between the cover and the case is adjusted, an irradiation angle of light emitted to the outside from the LED units is controlled.
