Description

Illumination range control device to prevent light pollution

The present invention relates to a device that can adjust the irradiation range in order to prevent light pollution caused by the lights installed along the street for the safety and security of street traffic, and more specifically to the range of light irradiated from the lamp The present invention relates to a lighting range control device for preventing light pollution, which can be easily adjusted according to the horizontal situation.

Generally, a lighting lamp refers to a lighting facility installed at the edge of a road for accident prevention and crime prevention by securing the visibility of a driver or a pedestrian on a road such as a dark road or a sidewalk, and the structure of most lighting lights is fixed vertically on the ground. It is common to install a lamp so that the light provided from the light source is directed downward at the tip of the post.

These lamps have a highway type that bends the ends according to the type and installs the lamps at the ends, a bracket type that installs the lamps on the branches extending horizontally at the ends of the poles, and a head type that installs the lamps on top of the poles It is very dark depending on its purpose, so it is easy to find the location of the vehicle, ship, airplane, etc. that operate at night for security, etc. to be installed for safety in areas where crime or accident may occur. It can be divided into signs installed for the purpose.

In addition, as a light source for providing illumination of a lighting lamp, a high-pressure mercury lamp, a fluorescent lamp, a sodium lamp, a general electric bulb, and the like are used. Such a conventional lamp needs to consume high power in order to display the required illuminance as a lamp. In addition, since the light tends to scatter in all directions, it does not accurately reflect the required range of light. In recent years, low power efficiency, improved illuminance, long life, and various colors are used. LED lighting is mainly used because of the advantage that harmful wavelengths are not emitted.

On the other hand, in recent years, due to the development of leisure culture and increase of night service business due to the increase of national income, bright lights such as daytime are provided from the lights. Due to the excessive light generated from these lights, In addition to the damage to life, the damage caused by lighting is serious enough to enact the 'light pollution by the artificial lighting' along with the word 'light pollution'.

For example, in the case where plantations for crops such as lost water or various vegetables are adjacent to the lamps, these grown crops are healthyly grown and developed due to confusion between day and night due to the bright lights of the lamps. As a result, the yield is greatly reduced, and house farms adjacent to the roadside continue to complain of damage to lighting.

In addition, when the livestock is adjacent to the lamp, livestock such as cattle, pigs, chickens, and ducks may not get enough sleep by the light of the lamp. There was a problem of weakening and becoming vulnerable to disease.

In particular, when a single or shared house is located near a lamp, the lights of the lamp illuminate the room through windows and verandas, which disturbs the sleep of indoor residents and causes inconveniences such as glare. It became.

Conventionally, a device for adjusting the angle of the lamp head has been proposed as in Korean Patent Registration No. 10-1273322, but it is to be able to adjust the upper and lower angles in a state where it is installed on the post, so as not to illuminate any one of the lights. When the lamp head is leaned up or lifted up, the opposite side is further stepped and the light is illuminated in a wide range, and only the direction in which the light is irradiated can be adjusted up and down, but the irradiation range of the light cannot be adjusted.

Therefore, in order to adjust the irradiation range of the lamp, the fixed bracket combined with the lamp is moved before and after, but the size of the lamp head is inevitably increased to move the lamp effectively while providing the set brightness, and not to increase the size of the lamp head. When the small size of the lamp is combined, there is a problem in that it cannot function as a lamp because it cannot provide the set brightness.

In addition, in Korean Patent No. 10-1103600, two or more shading plates are installed in the lamp head to limit the irradiation angle of the street lamp, so that the irradiation range of the lighting is adjusted, but this is required to adjust the irradiation range before installing the lamp head. In order to predict the shading plate, and after installing the lamp head, there is a problem in that it is inconvenient to adjust the irradiation range of the lamp, such as fixing the lamp head and removing all the lamps in order to adjust the irradiation range again.

In addition, Korean Utility Model Registration No. 20-0375310 discloses a light shielding device for a street lamp, which can adjust the lighting range as shown in FIG. 1, which includes a lamp shade 1 and a lamp shade installed therein.

It is configured to be coupled to the lower surface of the light shield plate 31 is interlocked, so that the irradiation range provided through the lamp (L) is adjusted as the light shield plate 31 is rotated.

However, in the above-described conventional technology, the light shielding plate 31 to adjust the irradiation range is installed under the lamp L, so that the area to be provided with light is obstructed by the light shielding plate 31. There was a problem that goes beyond the original purpose of the installed light to illuminate the place.

In addition, when the light blocking plate 31 completely covers the opened area of the irradiation hole 22 for the purpose of light blocking, heat generated during the operation of the lamp L may not be discharged, and may be reflected through the light blocking plate 31. The lighting (L) is overheated by the illumination, there is a problem that the replacement needs due to frequent failures increased.

In addition, since the light-shielding film 3 cannot be held in a fixed state, the light-shielding film 3 is arbitrarily rotated by strong wind or vibration, which makes it difficult to maintain the irradiation range.

Accordingly, the present invention is to solve such a conventional problem, it is possible to easily adjust the irradiation range of the light provided from the lamp so that light pollution does not occur, light pollution that can maintain a steady state of the irradiation range is set It is to provide a lighting range control device for preventing.
