More particularly, the present invention relates to an LED lamp having an electromotive force (EMF) And an EMF shielding function for collecting light from the EMF shielding material in a liquid state and removing the EMF shielding material from the ground through the ground.

Description

{LED LIGHT APPARATUS HAVING EMF SHIELDING MEMBER}

The present invention relates to an LED lamp having an electromotive force (EMF) shielding function. More particularly, the present invention relates to an LED lamp having an electromotive force (EMF) To an LED luminaire having an EMF shielding function capable of collecting in a liquid EMF shielding material and removing it through a ground through a ground.

The present invention relates to an LED lamp having an EMF shielding function, and more particularly, to an LED lamp having an LED module having a lamp case mounted on a ceiling or a wall of a room and a plurality of LEDs arranged on a printed circuit board, And a light emitting unit for emitting light emitted from the LED. The OLED may be formed on the light-transmitting unit to collect the EMF generated from the LED lamp, And an EMF shielding function configured to form a grounding portion for inducing the collected EMF to the earth in electrical contact with the electrolyte.

Generally, the LED lamp is composed of an electric and electronic circuit, and is equipped with an LED module that emits light when power is supplied.

Such an LED luminaire has electromotive force (EMF) generated when an electric or electronic product is powered, but due to lack of recognition of EMF, methods for shielding EMF are not applied to electric and electronic products. It is a social issue because it causes physiological changes and exacerbates health when exposed to EMF.

This electromotive force (EMF) is a force that moves electricity from a higher electric potential to a lower electric potential at two points where electric potential is different, and this force is called electromotive force (EMF).

In order to remove such EMF, the present inventor filed a Korean Patent Application No. 10-2013-0010144 entitled "EMF shielding member having a grounding portion formed therein ".

The EMF shielding member having the grounding portion includes a conductive EMF shielding member including an EMF shielding material having conductivity, and a grounding portion having excellent conductivity, which is formed at one end of the EMF shielding member to smoothly guide the EMF.

The EMF shielding member may be formed of a mixture of an insulating polymer and an EMF shielding material at a predetermined ratio, or may be coated with an EMF shielding material on the surface of an insulating substrate, followed by applying conductive ink, drying or forming a connection portion with a conductive tape.

However, transparency deteriorates by mixing a large amount of filler in order to effectively shield the EMF by using a solid form of EMF shielding material.

In general, the luminaire is a product with high power consumption, so it is desirable to increase the light efficiency while minimizing the power consumption.

As described above, when using a solid EMF shielding material that lowers the transparency, there is a problem of increasing power consumption.

In addition, when the solid EMF shielding material is used, it is difficult to realize various colors of light transmitted through the light-transmitting portion in aesthetic colors to the limit of the color of the shielding material when the three-color LED chip is not used.

Therefore, in the present invention, in order to prevent the human body from being exposed to the EMF generated by the LED lamp when the LED lamp is used, a shielding part capable of collecting the EMF is formed on the entire surface in the direction in which the light is emitted from the LED, A luminaire is required.
