The present invention relates to an LED illumination light, and more particularly, to an LED illumination light, and more particularly, to a method of manufacturing an LED illumination light, To an LED light which is prevented from origin.

In general, the illumination lamp is an initiator to revolutionize the human civilization as a means of illuminating the user to recognize objects in the dark by converting electric energy into light energy by receiving power, For example, the incandescent lamps developed for the first time generate more heat than light and can be manufactured at a low cost, but the use of the incandescent lamps has been avoided.

Although the above-mentioned disadvantages are overcome by fluorescent lamps, it has the advantage of saving energy by converting electric energy into light energy rather than a light bulb. However, since the time required for lighting is long and its life is short, Media.

As a light emitting diode (LED), which has been developed in order to meet this demand, it is getting a lot of popularity as an illumination light because it has a high illuminance with small power and its lifetime is remarkably long for several years without any special repair.

In recent years, an LED illumination lamp of the same type as a fluorescent lamp has been proposed and commercially available. In such a fluorescent lamp type LED illumination lamp, a printed circuit board in which a plurality of LEDs are arranged in a row on a main body of a long bar type, A translucent illuminating cover is fitted to the main body, and a reflecting member is assembled inside the illuminating cover.

Here, the reflection member reflects light emitted from the LEDs to both sides of the illumination cover, so that light can be irradiated from both sides of the illumination light.

However, the above-described conventional techniques have the following problems.

The conventional fluorescent lamp type LED illumination lamp is constructed such that the reflection member is separately assembled into the interior of the illumination cover, so that the reflection member must be fabricated separately and assembled, thereby significantly reducing the productivity of the illumination lamp itself.

In addition, in the conventional LED illumination lamp, the light of the LED directly passes through the illumination cover and irradiates light to the outside, which causes a problem of glare caused by the point light source formed by the LED.
