Description

LED lighting device with light pollution prevention structure The present invention relates to an LED lighting device having a light pollution prevention structure, and more specifically, to an LED lighting device having a light pollution prevention structure that can prevent damage caused by light pollution in advance by adjusting the direction of light irradiation so that light is irradiated only to specific areas that require light, and additionally allows the direction and angle of light pollution prevention to be easily set during on-site installation according to site conditions, and also allows the light pollution prevention state to be automatically adjusted according to day and night conditions. Recently, due to the development of leisure culture and the growth of night service industries, the number of people active at night has increased, leading to a growing trend of installing lighting fixtures that provide bright light to illuminate roads, sidewalks, and the like. However, as the installation of lighting fixtures increases, light pollution is occurring in which plants cannot distinguish between night and day and cannot grow normally due to the phenomenon where the lighting fixtures are too bright or too numerous, maintaining a state as bright as day even at night, and nocturnal animals cannot properly hunt for food or mate, causing disruption to the ecosystem and harm to people's lives such as sleep disorders. As a result, the damage caused by lighting devices has reached such a serious level that a law to prevent light pollution from artificial lighting has been enacted. In order to prevent light pollution as described above, a high-efficiency light fixture for preventing diffuse reflection may be used, comprising a mounting stand provided at the rear of a case, a lamp connected to the mounting stand, a reflector positioned above the lamp to reflect the light of the lamp, and an anti-diffuse reflection unit positioned at the bottom of the case to control the direction of the light of the lamp, wherein the anti-diffuse reflection unit comprises a guide rail installed at the bottom of the case, a guide member moving along the guide rail, a barrier formed at the bottom of the guide member, a catch formed at the rear of the barrier, a hinge portion provided spaced apart at a certain distance from the rear of the barrier, and a catch member rotatably installed at the hinge portion. However, the anti-glare unit of the aforementioned registered patent No. 10-0939042 is installed only on the lower side of one side and the lower side of the case, and since it controls the direction of light irradiation only in the direction where roads, sidewalks, etc. are located or in the opposite direction of roads, sidewalks, etc., it is difficult to completely block light irradiated into unnecessary areas. Furthermore, because the anti-glare unit must be installed on the case of the lighting fixture according to the direction of light irradiation, there is a problem of increased inconvenience, installation time, and installation costs during the installation process. In addition, since they are manufactured according to the case size of lighting fixtures such as streetlights, there is a problem that they may fall due to product defects, aging, or improper installation, potentially causing damage to surrounding facilities and casualties. Therefore, there is a need for a light shielding device that can adjust the direction of light in all directions so that it is directed only to the areas where it is needed, while minimizing damage to surrounding facilities and casualties. In addition, Korean Utility Model Registration No. 20-0391166 discloses a light-blocking device for streetlights. The light-blocking device for streetlights according to this utility model registration includes a light-blocking plate composed of two side plates and a rear plate, and also includes a plurality of fixing bands that are fixedly installed on the front and rear of the upper surface of the side plates, and have a catch portion formed on the inner lower side that is caught and fixed to the lower part of the bulb body, and a corresponding fixing portion formed on the upper side. Such a light-blocking device for streetlights is coupled to a streetlight case by means of a plurality (4) of fixing bands. In addition, this shading device for streetlights features multiple ventilation holes formed in the side and rear plates to dissipate heat from the streetlight bulb and reduce wind resistance. This design solves the aforementioned problems by limiting the direction of the streetlight beam to the road, while being easy to manufacture due to its simple structure. However, since the fixing band itself cannot achieve sufficient connection with the street light case, this design includes a catch to engage with the street light; however, there is a problem in that additional design is required for the street light case to engage with this catch, a
