The present invention relates to an LED lamp configured to be discharged so that no gas adheres to the inner surface of the lens.

Generally, a light emitting diode (LED) refers to a light emitting device made of a semiconductor that converts electrical energy into light energy.

The color emitted from the LED creates a wavelength depending on the composition of the semiconductor chip elements and determines the color of light.

Types of LEDs include Infrared Emitting Diode (IRD) and Visible Light Emitting Diode (VLED).

IRED stands for Infrared LED chip. This chip is processed and used for TV remote control, optical switch, IR LAN, wireless digital data communication module, and VLED stands for Visible LED chip. Red, green and orange colors were developed. Chips are assembled into lamps and used as a light source for displaying various electronic products, as well as signals and electronic signs.

In addition, LED lamps using LEDs are used in all fields that replace incandescent lamps because they consume less power and are more environmentally friendly.

However, the conventional LED lamp has a structure in which the LED elements are arranged in one direction only has a disadvantage in that the blind spot (死角) occurs and the side where the LED is not installed is dark, the reflection shade must be installed separately to solve this problem There is a problem.

In addition, the conventional LED lamp has a problem that the gas generated therein is fixed to the inner surface of the lens due to the lens is blurred, thereby reducing the illuminance of the LED lamp.

The present invention is to solve the above problems, the LED element is illuminated in the radial direction as well as the upward direction of the heat dissipation case is not a blind spot (死角) does not occur to improve the illuminance and illumination angle, occurs when the LED element is lit The purpose of the present invention is to provide an LED lamp in which the gas is discharged to the outside of the insulating case so that the gas is not fixed to the inner surface of the lens.

LED lamp of the present invention to achieve the above object is a heat dissipation case is formed with a plurality of heat dissipation fins on the outer surface; A side PCB substrate installed inside the heat dissipation case and equipped with an LED element that emits light when electricity is supplied; An upper PCB board installed inside the heat dissipation case and equipped with an LED element that emits light when electricity is supplied; A lens coupled to an upper portion of the heat dissipation case to cover the side PCB and the upper PCB; And an insulating case fastened to the lower portion of the heat dissipation case.

Here, at least one gas outlet is formed at a lower portion of the insulation case, and a filter is installed at the gas outlet to discharge gas generated inside the heat dissipation case through the gas outlet, and the filter is configured to dissipate foreign substances and water. Effectively prevents penetration into the case.

The heat dissipation fins are preferably evenly arranged in the longitudinal direction of the heat dissipation case, and are formed in a curved shape.

As described above, according to the present invention, the LED element is illuminated in the radial direction as well as in the upward direction of the heat dissipation case so that no blind spots are generated, thereby improving illuminance and illumination angle, By properly discharging the gas out of the insulating case, the gas does not stick to the inner surface of the lens, effectively preventing the lens from clouding.

Hereinafter, an LED lamp according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
