Description

Outdoor lighting device which can prevent light pollution {OUTDOOR LIGHTING APPARATUS FOR PREVENTING LIGHT POLLUTION}

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

In general, a lighting device includes a light source and emits light by illuminating a light emitted from the light source to a predetermined range. Examples of the lighting device may be a street lamp installed on a street lamp post, a lamp used to be installed on a wall or ceiling of a building.

Incidentally, incandescent lamps, fluorescent lamps, three wavelengths, and the like are generally used as light sources of the lighting device, but they have disadvantages of high power consumption and short lifespan. In order to remedy this drawback, recently, a technology that uses a liquid light-emitting diode (LED), which consumes relatively little power and has a long life, is drawing attention.

Lighting devices using LEDs have been proposed to be able to freely adjust the irradiation direction by providing a rotatable adjustment of the lighting unit of the LED lamp fixed in the irradiation direction. However, in the conventional lighting device, when the irradiation direction is adjusted, the light source of the lighting unit is irradiated intensively in one of the adjusted directions, so that the light source cannot be irradiated in a wide range. If you do not adjust the direction of irradiation or install a separate streetlight separately, there is a problem that can not be investigated in a wide range.

Therefore, in recent years, in order to irradiate a light source in a wide range, a reflecting plate 310 is installed in the LED lamp so that it can be irradiated in a wide range.

However, such a conventional LED lighting device has recently been pointed out as a cause of light pollution due to the issue of negative issues associated with excessive use of artificial light due to excessive commercialism, competitive psychology, discrimination, and the like.

Light pollution causes problems such as disturbing sleep to humans, disturbing astronomical observation, disturbing reproduction to wild animals and plants, disturbing ecosystems, and wasting energy.

Such light pollution generates upward and invasive light in the lighting device. When the lighting device is installed in a normal position, the upward light refers to the light beam emitted in the direction above the horizontal line. It accounts for about 18% and about 0.2% of annual electricity consumption in Korea, which is a factor of energy waste and is pointed out as a major factor that obstructs astronomical observation.

In other words, the conventional outdoor LED lighting device has an upward light and an invasive light, causing light pollution, and recently tightening regulations. Lighting devices have not been developed yet.

That is, as shown in the drawings, the present invention is fixed between the LED module (200, 200 ') and the reflection panel (300, 300') between the first side plate 110 and the second side plate 120. However, by opening both the front and rear can achieve the effect of further increasing the thermal conductivity.

As described above, the embodiments of the present invention have been described with respect to specific embodiments, but various modifications can be made without departing from the scope of the present invention, and the accompanying drawings are attached to assist in understanding the embodiments of the present invention. It is not limited.

In other words, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and various modifications and changes may be made by those skilled in the art to which the present invention pertains.

Those skilled in the art will appreciate that the present invention may be embodied in a modified form without departing from the essential characteristics of the above-described substrate. Therefore, the disclosed methods should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.
