  • Patent number: 11935703
    Abstract: A multilayer electronic component has a body and a non-conductive resin layer. The non-conductive resin layer includes a body cover portion disposed in a region of an external surface of the body in which an electrode layer of an external electrode is not disposed, and an extending portion extending from the body cover portion between the electrode layer and a conductive resin layer of the external electrode, to thereby suppress arc discharge, improve bending strength, and improve moisture resistance.

  • Patent number: 10527271
    Abstract: An LED lighting device is provided. The LED lighting device may include a light source configured to emit a light of first color temperature, second color temperature, and third color temperature and a switch electrically connected to the light source to control the light source to emit the lights of the first color temperature, the second color temperature, and the third color temperature, respectively. The light source includes a first light source configured to emit a light of a first color temperature, and a second light source configured to emit a light of a second color temperature that is different from the first color temperature, and the light source emits a light of a third color temperature between the first and second color temperatures when the switch parallel-connects the first light source and the second light source.

  • Patent number: 8770806
    Abstract: A light emitting diode (LED) lighting module is provided including an LED array, and at least one of a diffusing portion and a reflecting portion. The LED array, equipped with at least one LED, may include a side wall which surrounds the at least one LED. The diffusing portion may be detachably coupled to the LED array and may include a diffusion plate which diffuses light emitted from the at least one LED The reflecting portion may be detachably coupled to one of the LED array and the diffusing portion and may reflect light emitted from the at least one LED. The LED array may be selectively coupled with the diffusing portion, the reflecting portion, or both the diffusing portion and the reflecting portion.
