Description

Field of the Invention [0001] The present invention relates to an LED lighting device having an angle adjusting and shading function,

The present invention relates to an LED lighting apparatus, and more particularly, to an LED lighting apparatus which is provided on a street lamp and has an angle adjusting function and a light shielding function and is freely adjustable in an irradiation angle range so that light is irradiated in a desired part and a desired direction .

Since the invention of LED, there have been many cases where LED lamps using LEDs have been used as lighting. In recent years, the use of harmful substances has been regulated due to environmental pollution. However, from the viewpoint of energy saving, incandescent lamps or fluorescent lamps LED street lamps with various advantages such as low power consumption, excellent illuminance and long life time compared to the lighting lamp are spreading, and street lamps in the street are being replaced with LED lamps using LED lamps.

Since the conventional LED street lamp uses several LED lamps using LEDs to illuminate within a predetermined angle only in a certain direction, there may be a problem of overheating due to an adjacent LED lamp, There is a problem in that it is not possible to apply all the lights of the road from the narrow lane to the wide lane, for example.

In addition, if the angle of the light emitted from the LED lighting module, that is, the light distribution angle is unnecessarily large, the conventional LED streetlight may cause illumination pollution due to light deviating from the effective light distribution angle, or may cause glare to the driver, which may interfere with operation. In addition, when the light distribution angle is narrower than required, the intermediate illuminance between the streetlight and other neighboring streetlights is lowered, resulting in a dark area.

However, the conventional LED street lamp adopting the LED element as a light source has a structure in which it is impossible to adjust the light distribution angle separately according to the installation interval and height of the streetlight, because it is manufactured in a factory in a factory.

In addition, in a light source using a high-pressure discharge lamp, the light distribution is controlled by a reflection plate, but the light distribution is controlled by using a lens attached to the LED while using the LED as a light source.

However, as shown in FIG. 1, such an LED module is not suitable for all roads in Korea because it is formed by a light distribution that gives a constant reference to a certain road width, and also, light is emitted to the back of the luminaire or a point outside the road, This occurs and energy is also wasted.

In addition, a plurality of angle-adjustable street lamps, such as the one disclosed in Japanese Patent No. 10-0622607, are known, and they are commonly used to adjust the angle by using a hinge device. However, since the streetlight capable of adjusting the irradiation direction according to the prior art employs a ball joint or a hinge device, the number of assembling holes increases, and when the angle is adjusted by a ball joint or a hinge device, It is necessary to provide a separate member for supporting the street lamp head.
