In order to solve such a problem, the use of an illumination lamp having a light emitting diode (LED) as a light source has been increasing in consideration of recent consumption of electric power, lifetime of illumination lamp, brightness and diffusion range.

In order to maximize the illumination effect according to the surrounding environment such as the installation place and the position, it is preferable that the lighting apparatus using such a light emitting diode is irradiated with light in a certain area. For this purpose, A structure capable of irradiating light to a desired area by adjusting the angle is required.

Such a lighting apparatus includes an illumination lamp and a bracket for mounting an illumination lamp on a fixing member such as a ceiling, and the illumination lamp is fixed to the bracket after the angle of the illumination lamp is adjusted to a desired angle. At this time, the lighting lamp is installed by fastening and fixing the bracket using bolts.

However, in the conventional lighting apparatus having the angle adjusting function, since the lighting lamp is simply fastened to the bracket with the bolt, the fastening force of the bolt may be lowered by external physical impact. In this case, there is a problem that the angle of the lighting lamps fastened to the bracket is not maintained at a certain angle with respect to the horizontal plane, and that the bracket is moved in a direction parallel to the horizontal plane. Especially, the weight of the light is increased, and the frequency of this problem increases.

If the bolts fastening the lighting lamp to the bracket are severely loosened, there is a risk of safety accidents due to falling of the lamp.
