Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an outdoor lighting device capable of preventing light pollution,

The present invention relates to an outdoor lighting device capable of preventing light pollution.

In general, an illumination device includes a light source, and irradiates the light generated from the light source to a predetermined range to illuminate the light. Examples of the lighting device include street lamps installed in the street lamps, walls of a building, and illumination lamps installed on a ceiling.

Generally, an incandescent lamp, a fluorescent lamp, a three-wavelength lamp, and the like are generally used as the light source of the lighting device, but the power consumption is large and the life span is short. In order to overcome such disadvantages, recently, a technique of using a light-emitting diode (LED) with a relatively low power consumption and a long life is attracting attention.

An illumination device using LEDs has been proposed in which an illumination part of an LED lamp having a fixed irradiation direction is rotatably adjustable so that the irradiation direction can be freely adjusted. However, in the conventional illumination apparatus, the light source of the illumination unit is intensively irradiated in one direction when the irradiation direction is adjusted. Therefore, the light source can not be irradiated over a wide range. It is impossible to irradiate a wide range unless the direction of irradiation is individually adjusted or a separate street lamp is additionally installed.

Therefore, in recent years, in order to irradiate a light source in a wide range, a reflector 310 is installed on an LED lamp so that it can be irradiated over a wide range.

However, such a conventional LED lighting apparatus has recently been pointed out as a cause of causing light pollution due to a negative problem related to excessive use of artificial light due to excessive commercialism, competition psychology, discrimination awareness and the like.

Light pollution can cause sleep disturbance, disturbance of astronomical observations, reproductive disturbance to wild birds and plants, ecosystem disturbance, and energy waste because of excessive light beyond necessity.

Such light pollution generates upward light and intruding light in an illumination device. Upward light refers to a light flux emitted in the upward direction of a horizontal line when the lighting device is installed at a normal position by design, and the amount of power used for outdoor lighting About 18% of the annual electricity consumption in Korea, about 0.2% of the annual energy consumption, which corresponds to a factor of energy waste, is pointed out as a major obstacle to astronomical observations.

In other words, the conventional outdoor LED lighting device has upward light and intrusion light, which causes light pollution. Thus, although the recent regulations are strengthened, it is necessary to prevent the ambient light pollution and to satisfy both the light- Lighting devices have not yet been developed.

The present invention includes the above-described structure. Hereinafter, the present invention will be described in more detail with reference to the above-described structure.

FIG. 7 is a view showing an installation example of an outdoor lighting device according to the present invention, and FIG. 8 is a view simply showing an optical path of the lighting device.

Referring to FIGS. 7 and 8, a process of assembly by an operator will be described first. The operator can attach the first LED module 200 and the second LED module 200 ', the first reflective panel 300 and the second reflective panel 300' to any one of the pair of side plates 110 and 120, The support bars 130 are assembled in the selected order.

For example, the support bar 130 is fixed by inserting fixing means of the bent support end plate 131 and fixing holes 111 of the side plates 110 and 120, and fixing means, A screw is inserted and tightened so as to communicate the folded reflective end plate 320 and the side plates 110 and 120, respectively.

At this time, the first reflection panel 300 is fixed in an upward inclined direction with one side of the reflection plate 310 facing the light emitting window 231 side of the LED modules 200 and 200 '.

The first LED module 200 has a fixing hole 214a of the coupling piece 214 formed at the end portion thereof aligned with the fixing hole 111 of the side plates 110 and 120, And is fastened to the plates 110 and 120. Here, the first LED module 200 is fixed in a downward inclined direction such that the light emitting window 231 is directed toward the reflector 310 side. That is, the first LED module 200 and the first reflection panel 300 are fixed to be inclined with respect to each other.

The second LED module 200 'and the second reflective panel 300' are fixed to the first side plate 110 in the above-described manner, respectively.

That is, as shown in the drawings, the present invention is characterized in that the LED modules 200 and 200 'and the reflection panels 300 and 300' are fixed between the first side plate 110 and the second side plate 120 However, by opening both the front surface and the rear surface, the effect of increasing the thermal conductivity can be obtained.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. It is not limited.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, disclosure methods should be considered from an illustrative point of view, not from a restrictive point of view. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
