Description

LED street light {LED streetlight}

The present invention relates to an LED street light, and relates to an LED street light installed at the center of a roadside or a central separator such as a national road, a highway, a pedestrian crossing, and the like.

Currently, the lighting market using LEDs (LEDs) is estimated to have more than 800 LED lighting companies in Korea.

An example of how LED lighting is in the spotlight is that Seoul has announced that it will replace all public lighting, including public buildings and road lighting, with power-efficient LED lighting by 2018, and all private lighting by 2030. The goal is to replace it with lighting.

LED lighting is known to be 5 times longer with about 50,000 hours of life while saving up to 80% of electricity compared to conventional lighting. Currently, 20% of Seoul's total power consumption and 37% of the city's power consumption are used as lighting equipment. If the lighting of all downtown buildings is changed to LEDs, the city's electricity consumption will be greatly reduced.

Therefore, it is necessary to cut and use the LEDs in unit lengths according to the illuminance of indoor and outdoor lightings set, and therefore, it is urgent to spread the LED lights, which require less construction cost and shorten the installation period.

The first frame 110 and the second frame 120 are disposed side by side with the vertical frames 130 interposed therebetween, and the pair of the vertical frames 130 also have the first frame 110 and the second frame. The frame 120 is disposed side by side to form an external shape having a rectangular frame shape.

In this case, the coupling frame 150 has a function of coupling the light source unit 140 between the vertical frames 130. To this end, the coupling frame 150 includes a plurality of coupling holes 153 formed through the lateral direction at predetermined intervals.

The light source unit 140 is formed of a plurality of unit modules 141, each of the unit modules 141 is provided with a lens member 142 for irradiating light on one side, the lens member 142 on the other side A heat dissipation member 143 is provided to dissipate heat emitted from the heat.

The heat dissipation member 143 is coupled to the coupling hole 153 formed in the coupling frame 150, and is spaced apart at set intervals.

Therefore, the unit module 141 may be spaced apart at set intervals according to the required illuminance or illuminance according to the installed height, and may be selectively used in combination.

For example, when used as a street light for city roads, because the surroundings are relatively brighter than other local roads, the unit modules 141 may be used in combination with each of the three unit modules 141 for each section set on the road, or may be a street light around a local road or highway. When installed in a relatively dark surroundings, in particular, in the region of the fog, especially in areas where frequent fog may be combined to provide a brighter illumination by combining the unit module 141 by five.

In addition, it is preferable to install a large number of unit modules 141 in combination such that a pedestrian crossing around a school, an intersection without a traffic light, a sharp turn section, and the like also provide brighter illumination.

Although not shown in the figure, a control unit (not shown) for supplying power of an appropriate voltage to the light source unit 140 and adjusting illuminance is disposed in the second frame 120.

The light source unit 140 is interposed between the unit module 141 and another adjacent unit module 141 and is provided with a gap maintaining unit 170 for maintaining a setting interval P between the unit modules.

The gap maintaining part 170 includes a first gap member 171 and a second gap member 172, which will be described later.

4 is a reference diagram illustrating a coupling state of the LED street light 100 shown in FIG. 1, and FIG. 5 is a cross-sectional view illustrating a unit module 141 of the LED street light 100 shown in FIG. 1.

4 and 5, in the LED street light 100 according to the present invention, the unit module 141 is selectively slidably coupled between a pair of the vertical frames 130.

The sliding member 144 and the guide member 131 is preferably a male and female coupling that is prevented from being separated in the vertical direction and the sliding direction, and although not shown in the figure is foreign matter between the sliding member 144 and the guide member 131 A sealing member may be provided to prevent moisture from penetrating.

As such, a plurality of unit modules 141 to be coupled on the vertical frame 130 may be selectively coupled to correspond to the lengths of the vertical frames 130.

In this case, the unit modules 141 are first coupled to the sliding member 144 on the guide member 131, and is fixed by screwing the heat dissipation member 143 and the coupling frame 150. In this manner, when the heat dissipation member 143 and the coupling frame 150 are fastened according to the number of the unit modules 141, one light source unit is formed.

Here, the light source unit is disposed so that the unit module 141 is spaced apart at the set interval (P), respectively, the set interval (P) is effective to increase the heat dissipation effect of the light source unit 140 by activating the natural convection of air There is.

To this end, the gap maintaining unit 170 interposed between the unit module 141 and another adjacent unit module 141 is provided at the set interval P.

The gap maintaining unit 170 includes a first gap member 171 inserted between the unit module 141 and another adjacent unit module 141 on the coupling frame 150.

In addition, the gap maintaining unit 170 is slidably coupled to the guide member 131 on the vertical frame 130 and is disposed between the unit module 141 and another unit module 141 adjacent to the second gap member 172. ).

The second gap member 172 is slidably coupled on the guide member 131 to set the gap between the first gap member 171 and the unit module 141 and another unit module 141 adjacent thereto. It is accompanied by the function of maintaining the P) and at the same time block the vibration between the unit module 141 and another adjacent unit module 141.

Accordingly, the first gap member 171 and the second gap member 172 may be formed of one or a plurality of materials selected from the group consisting of urethane resins, silicone resins, and emulsion resins having elastic or sealing forces.

As illustrated in FIG. 5, the vertical frames 130 may respectively reflect the light emitted from the lens member 142 in one direction, that is, the first frame 110 and the first frame 110. It is bent to protrude a predetermined height from the imaginary line connecting the two frames 120.

Unlike general lamps, light does not radiate to the point where light reaches in a circle, but because it is able to irradiate light having a rectangular shape, the amount of light in the overlapping part of the light is too high if general light uses multiple lights. It provides an effect that can supplement the problems such as irradiated or vice versa.

FIG. 6 is a reference diagram illustrating the fixing part 160 of the LED street light 100 illustrated in FIG. 1.

Referring to FIG. 6, the fixing unit 160 has a function of fixing the light source unit 140 on the support frame 180 as well as the lens member 142 in a state where the installation of the light source unit 140 is completed.
