Light distribution distribution variable street lighting equipment {A STREET LIGHTING EQUIPMENT FOR FLEXIBLE LIGHT DISTRIBUTION}

The present invention relates to a street lamp, and more particularly, the road surface illuminated by the street lamp is divided into a central part, a side part, and a front part based on the street lamp, and each area is selected so that the lighting and luminance and illuminance can be adjusted. This invention relates to a light distribution distribution variable street light fixture capable of varying a light distribution by attaching an LED as a light source and attaching an optical component such as a reflector or a lens.

When the street light fixtures used to illuminate the road, etc., are installed on a road with narrow road width, fewer lanes, or a large distance between streetlights, the street light fixtures should have more light emitted to the side than light emitted to the front of the street lamp fixture. For example, when the road is wide and the number of lanes or the distance between the street lamps is narrow, the light emitted from the front side of the street lamp may be larger than the light emitted from the side to achieve an effective road lighting environment.

However, the conventional street lamp mechanism cannot adjust the light distribution form in accordance with the road lighting environment as described above, but is provided only in a fixed light distribution form.

On the other hand, in recent years, the use of street light fixtures with a large number of LEDs, which have high energy efficiency and can be used semi-permanently, has been expanded. However, the street light fixture to which the LED is applied also has a fixed light distribution type, like a street lamp using a normal lamp, so that the road cannot be efficiently illuminated. However, by adjusting the quantity or light output of the LED, it is possible to simply adjust the illuminance and brightness or determine whether to turn on the light. It is difficult to obtain a sufficiently uniform brightness distribution on the surface, and there is a problem in that it is illuminated to an unnecessary area as well as an area to be illuminated.

For this reason, it is difficult to obtain the illuminance and luminance uniformity necessary for the driver, and there is a fear of causing various safety accidents at night due to glare caused by excessive lighting.

The present invention has been invented to solve the above problems, by dividing the road area to be illuminated in the center, side, front surface to selectively illuminate only the required area or to adjust the light distribution distribution to adjust the illumination and brightness An object is to provide a distributed variable street lighting fixture.

The center module is formed in the form of a vertical shape, the width of the cross section toward the lower portion, the lower end is formed to be open, it is preferable that the LED is mounted on the upper end eccentrically to the outside of the fixing plate.

The side module is formed of a front plate formed of a curved surface that is curved outwardly, and a curved surface that is curved outwardly and the bottom is formed to be bent inward, it is formed longer than the front plate is lower than the lower end of the front plate It includes a rear plate and a side plate to close the side of the front plate and the back plate spaced apart from each other, characterized in that the LED is mounted eccentrically toward the rear plate on the top and eccentrically to the outside of the fixing plate.

In addition, the front module, the front plate is formed of a curved surface that is curved outward, the lower surface is formed curved to the outside and the lower end is formed to be bent inward, the lower end of the front plate is formed longer than the front plate It is preferable to include a rear plate which is located at the lower side, and a side plate which closes the sides of the front plate and the rear plate spaced apart from each other, the LED is mounted eccentrically to the center of the fixing plate on the top.

According to the light distribution distribution variable street light fixture according to the present invention having the configuration as described above, the road area to be illuminated by the street lamp fixture divided into a central portion, a side portion, the front portion with respect to the street light pole, the change of the road width and the number of lanes, the distance change between street lamp poles Each part can be increased or decreased individually to suit the needs, and the light distribution of the street lamp can be changed by adjusting the light output of only the required part.

As a result, it is possible to improve the roughness, brightness, and uniformity of the road surface according to the characteristics of the road, to reduce the power used to illuminate unnecessary parts, and to prevent glare that may be felt by the driver or pedestrian.

Hereinafter, a light distribution distribution variable street lighting fixture according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 3, the light distribution distribution variable street light fixture 1 according to the present invention, the fixed plate 10 is fixed to the street lamp, and is installed on one side of the lower surface of the fixed plate 10, The central module 20 for illuminating the lower side of the street light fixture is provided inside the LED, and is installed on one side of the lower surface of the fixing plate 10 and is disposed on both sides of the central module 20, and the LED inside 50 is provided on the side module 30 and both sides of the street light fixture, respectively, and is installed on one side of the lower surface of the fixing plate 10, the front of the front module 40 and the side module 30 Is provided in, and provided with an LED 50 therein and includes a front module 40 to illuminate the front of the street lamp mechanism.

As a result, a plurality of LEDs are used as a light source and an optical component such as a reflector or a lens so that the road surface illuminated by the street light fixture can be divided into a center, a side part, and a front part based on the street lamp. The central module 20, the side module 30, and the front module 40 may be configured to change the light distribution of the street lamp according to the change in the width and the number of lanes and the distance between the street lamps.

The fixed plate 10 is fixed to the street lamp column (not shown) is installed spaced apart from the road surface above the road surface. The fixing plate 10 has through-holes 11 formed at positions where the reflector plate and the LED 50 are to be described later, so that the LED 50 can be easily installed.

The central module 20 is provided at one side of the fixed plate 10, preferably at a portion adjacent to the street lamp column in the fixed plate 10.

Looking at the specific form of the central module 20, as shown in Figure 4, the bottom is formed in an open state so that the light emitted from the LED 50 can be irradiated on the road surface. Side plates 21 respectively positioned on the side surfaces of the center module 20 (lower left and upper right directions in FIG. 1) are formed to be curved outwardly so that the width thereof becomes wider downwards, but the width widens downwardly. It is formed in the form of a bell with this decreasing shape. The front and rear plates 22 disposed before and after the side plates 21 spaced apart from each other are formed substantially perpendicular to the fixed plate 10.

In addition, when the LED 50 is disposed on the upper end of the center module 20, when the LED 50 is turned on in the center module 20, the light irradiated from the LED 50 is transferred to the center module 20. After being reflected by the side plate 21 or the front and rear plates 22, the direct portion of the street lamp mechanism 1 is illuminated.

Side modules 30 are provided on both sides of the center module, respectively. The side module 30 has a front plate 31 and a rear plate 32 each formed in a curved surface before and after the direction in which the light emitted from the LED 50 is irradiated (left lower, upper right in FIG. 1) are disposed. As shown in FIG. 5, the front plate 31 is formed in the form of a curved surface outward so that the light emitted from the LED 50 is reflected to the rear plate 32 without being dispersed. In addition, the back plate 32 is formed in the form of a curved surface outward, it is formed to face inward toward the bottom. At this time, since the front plate 31 is formed to be shorter than the length of the back plate 32, a space is formed between the bottom of the front plate 31 and the bottom of the back plate 32, the light emitted from the LED through this space Light can pass through. The back plate 32 reflects most of the light of the LED 50 to the front of the back plate 32 to illuminate the left and right sides of the fixing plate 10 in the direction in which the side module 30 is installed. Here, the curvature of the front plate 31 and the back plate 32 is determined according to the environment of the place where the street lamp mechanism 1 is installed, to adjust the irradiation area.

The side plate 33 of the side module 30 is formed substantially perpendicular to the bottom of the fixing plate 10 and is spaced apart from each other, the front plate 31 and the back plate 32 of the side module 30 Close both ends of the

As shown in FIG. 6, the front module 40 has a shape similar to that of the side module 30. The front module 40 is the front plate 41 and the rear plate 42 is disposed in the front and rear direction of the irradiation direction (left upper direction of Figure 1) is disposed, the front plate with the side plate 43 is spaced apart from each other Both ends of the 41 and the back plate 42 are closed. The front plate 41 and the rear plate 42 is formed in a curved shape that is curved outward, the rear plate 42 is formed to be bent inward toward the bottom. Since the length of the front plate 41 is shorter than the length of the back plate 42, the LED to the area to be illuminated through the space formed between the bottom of the front plate 41 and the bottom of the back plate 42 Light emitted to 50 is irradiated. The front module 40 also allows the rear plate 42 to reflect most of the light so that the front of the fixed plate 10 is illuminated.

The front module 40 is also formed in a similar shape as the overall side module 30, but the curvature of the front plate 41 and the rear plate 42 is determined according to the situation of the installation place.

The center module 20, the side module 30, and the front module 40 are respectively installed on the fixing plate 10 so that the opening is opened toward the area to be illuminated. That is, as shown in Figures 1 to 3, the center module 20 is provided on the fixed plate 10, the side module 30 is located on both sides of the center module 20, the center module The front module 40 is located in front of the (20).
