Description

[0001] The present invention relates to a wireless charging type LED lamp device,

The present invention relates to a wirelessly-charged LED lighting device, and more particularly, to an LED lighting device that wirelessly charges an LED lighting device, thereby securing visibility and visibility for a predetermined period of time in the event of an emergency such as power outage, fire occurrence, The present invention relates to a wirelessly-charged LED lighting apparatus and a lighting apparatus.

Light emitting diodes (LEDs) are semiconductor devices that emit light by passing current through a compound such as gallium arsenide. LEDs are needed to create a small flashing light when the hard disk is spinning in the computer, a large electric signboard on a building in the city center, and invisible rays that send a signal to the TV body every time the TV remote control button is pressed.

The LED has a structure in which a positive charge particle called an electron and a hole is emitted from the center of the electrode and emits a photon of light when an electric current passes through a conductive material having an electrode attached thereunder. The color of the light changes according to the properties of this material.

Since the development of red LEDs in the United States in 1968, yellow, green, blue, and white LEDs have been used throughout our lives. White LED was produced by Nichia in Japan, HP in USA, and OSRAM in Germany, which can be used as an indoor lighting fixture. It was developed by Prof. Park Seong-joo of Kwangju Institute of Science and Technology in February 2000.

Professor Park Sung-ju's team succeeded in developing the world's first amorphous silicon quantum dot LED in April 2001. In particular, LEDs using amorphous silicon quantum dots can freely adjust the size of the quantum dots, so that only the size of the quantum dots can be adjusted freely to produce full-color light.

Korean Patent Laid-Open No. 10-2008-0032519, published on Apr. 15, 2008, relates to a charging device for a portable electronic device, and more particularly to a solid-state charging system using inductive coupling. The non-contact charging system includes a first charging unit including a primary coil and a wireless receiving module, a second charging unit including a secondary coil and a wireless transmission module magnetically coupled to the primary coil, And a battery supplied with a charging voltage from the charging unit. In particular, the first charging unit may include means for generating an AC power pulse having a frequency equal to or higher than a commercial frequency as the commercial AC power is applied, and applying the generated AC power pulse to the primary coil to induce a high frequency AC voltage pulse in the secondary coil; The second charging unit includes means for transmitting the charging state information of the battery to the first charging unit by using the inter-pulse idle time of the AC voltage pulse induced by the secondary coil .

However, since the conventional wireless charging device is used only for a very limited purpose such as a mobile phone, it is applied to an LED lighting device and is used as a main means for securing a certain time of view when an emergency situation such as power outage, fire occurrence, It needs to be improved.
