[0001] Wireless power-supplied LED light [0002]

The present invention relates to a wireless power supply type LED lighting lamp, and more particularly, to a wireless power supply type LED lighting lamp, which increases the efficiency of wireless power transmission to reduce the electric power consumption and does not separate from the lighting main body even when an impact is applied to the LED lighting body, It is possible to easily attach and detach the LED lighting fixture to the lighting fixture by using a magnet and to replace the LED lighting fixture with other LED lighting fixture as required, So that the replacement cost can be reduced.

A light emitting diode (LED) is a light source that emits light when a voltage is applied to a semiconductor. Since the high luminous efficiency of a gallium arsenide pn junction was found in 1923, , And in the late 1960s they were put to practical use.

Suitable materials for LEDs are gallium arsenide, gallium phosphide, gallium arsenide, gallium arsenide, gallium arsenide, gallium arsenide, gallium arsenide, gallium arsenide, gallium arsenide, 2B or 3B compound semiconductors such as gallium-aluminum-arsenic, indium phosphide, indium-gallium-phosphor, etc. are used. These LEDs are smaller than conventional light sources, have a long life, Because it converts directly to light energy, it has the advantages of low power and efficiency. Particularly, the power consumption is very low at 1/8 of the bulb and 1/3 of the fluorescent lamp, and the filament is not short-circuited like a bulb, and the lifetime is usually 50,000 to 100,000 hours, which is semi-permanent.

The LED lighting device using LED which has many advantages compared to the conventional light source is the most demanded as the display light of mobile or IT devices requiring ultra-thin and high efficiency display, and it is most demanded in the automobile, traffic light, street light, sign, Indirect lighting, agricultural lighting, fishing tongs, etc., are being used increasingly. Particularly, the LEDs used in the lighting fixtures should be installed with different illuminance and color temperature of the LEDs depending on the installation location. However, Setting the illuminance or the color temperature to a different value consumes a lot of time and cost at the time of installation.

In such a conventional LED lighting lamp, electricity has been used to be transmitted to the wire, but it has been proposed to transmit electric power wirelessly, so that the electric power is wirelessly transmitted. It is possible to wirelessly transmit data. The applicant of the present invention has proposed that it is possible to wirelessly illuminate an LED lighting lamp with a wireless electric transmission system. However, in this method, a coil is etched on a substrate, but this method has a problem in that the efficiency of transmission of the radio power is remarkably reduced and the electric power is inefficiently consumed.

As described above, the conventional LED illuminating lamp can perform various illuminations such as red, white, green, and pink by using various colors. However, in general, there is a problem that the use of the white LED illuminating lamp is monotonous.

When the LED lighting fixture is mounted on a ceiling and the LED lighting fixture is priced with an elongated object such as a stick or a pipe, the LED lighting fixture is detached from the lighting fixture and falls to the ground.
