LED LIGHTING APPARATUS ADJUSTABLE LIGHT DISTRIBUTION

摘要

The present invention relates to an LED lighting apparatus which has a distance between an optical lens and an LED module. The LED lighting apparatus capable of adjusting light distribution can increase or diffuse the amount of light emitted to an object by horizontally moving the LED module from the focus of an optical lens. According to the present invention, the LED lighting apparatus can smoothly perform marine survey in a specific environment such as deep sea by diffusing light to observe with a wide range or condense light emitted from an LED light source through the optical lens on an object to be checked.
