  The present invention relates to a lighting device, and in particular, has a cover that uniformly diffuses light from a light source, uniformly diffuses light emitted from a light source module by the cover, and extinguishes a light emitting point of the lighting device from the outside. It is related with the illuminating device which can do.

  Fluorescent lamps are used as lighting in homes and factories. However, since the fluorescent lamp uses an AC power supply, a flicker phenomenon occurs, which adversely affects the user's eyes. Furthermore, the fluorescent lamp consumes a lot of electric power during use, and it is necessary to apply toxic substances such as fluorescent powder in the manufacturing process, and these toxic substances have a bad influence on the global environment.

Currently, there are lamps that use LEDs as light sources in the market, and they have the advantages of low power consumption and being friendly to the global environment. However, the LED has a strong directivity, and if not processed, a light emitting point is generated in the LED lamp, and this phenomenon has a bad influence on the eyes of the user.
