Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an adjustable angle-

The present invention relates to an angle-of-view adjusting device for a luminaire, and more particularly, to an angle-of-view adjusting device for a luminaire which is capable of controlling a tilting structure through a knob rotatable in two directions, To a regulating device.

The most typical street lamps and tunnels in the luminaire are lighting facilities installed along the street for safety and security of road traffic.

Depending on the installation location such as the highway, the main road of the city area, the road of the commercial district, the road of the residential district, etc., a suitable type is used. According to the form of the streetlight pole, a highway type which is bent at the end of the pole, A bracket type which extends a branch horizontally at the end of the crown and a back to the top of the crown,

Typically, high-pressure mercury lamps, high-pressure sodium lamps, metal halide lamps, and the like are widely used as light sources for streetlights. However, when such a light source is used, the power consumption is large and the lifetime is limited, so that the maintenance cost is low.

In recent years, there has been a proliferation of high-brightness light emitting diode (LED) streetlights having various advantages such as low power consumption, excellent illumination, and long life time.

However, in using such a high-luminance light emitting diode, the following disadvantages are pointed out.

If the illumination angle of light generated from the light source, that is, the light distribution angle is unnecessarily large, scattering light deviating from the effective light distribution angle may cause illumination pollution or glare to the driver, which may interfere with operation. In addition, when the light distribution angle is narrower than required, the mid-portion illuminance between the streetlight and other neighboring streetlights is lowered, resulting in a dark area. That is, it is difficult for the driver to recognize obstacles on the road surface due to uneven brightness of the road surface.

Therefore, it is important to set the light distribution to such a range that the light pollution is suppressed in the case of a streetlight, a security, or a tunnel, and the driver's glare is minimized while the dark area is not generated.

To this end, a reflector is mounted behind the LED light source to create a specific light distribution, or a cup-shaped reflector or LED (not shown) is used to generate a directional light with a full width of half maxium (FWHM) The lens may be used by putting it on the lens.

However, in order to spread the light in a wide direction, the light emitted toward the vertical front side of the LED light source must be refracted or reflected to the side. When the reflection plate is used as described above, the forward light is completely cut off, There is a complicated problem that needs to be added.

1, the conventional luminaire head 1 includes a cover 10 for covering a luminaire, a plate 23 for supplying power, an LED module 24 provided on the plate 23, And a protective cover 11 attached to a lower portion of the LED module 24 and serving as a diffusion plate.

However, according to the above configuration, there is a problem that the LED module 24 is fixed and the tilting angle can be set, which limits the range in which the light distribution can be controlled.

On the other hand, Korean Patent No. 10-0944521 ("Streetlighting Lighting Device") is disclosed as another method.

The lighting device for a streetlight includes a module case coupled to an upper portion of a streetlight post, a socket portion mounted to the module case through a rotating means and a tilting means so as to be rotatable and tilting and having one or more light emitting diodes And a heat sink for heat dissipation is provided on the other side of the lamp module.

In order to adjust the light distribution angle of the light source, the sockets to which the plurality of light emitting diodes are coupled are provided, thereby achieving the desired light distribution by dividing the direction of the light source, thereby making it possible to increase the efficiency of the light distribution by a uniform illuminance .

However, as described above, the method of manufacturing an illumination device by individually adjusting light sources having a plurality of narrow incident angles is problematic in that the productivity is reduced and the direction of each light source may be changed even after the installation process or installation, thereby decreasing the reliability.
