Street light according to an embodiment of the present invention, the street lamp is installed vertically on the ground, the street lamp including a light source, and is installed between the street lamp and the street lamp and installed at the upper end of the street lamp and supporting the street lamp It consists of an arm for.

The street lamp is formed on the ground and is coupled to an anchor bolt protruding from the base concrete. In order to combine the anchor bolt and the street lamp, a plate is provided at a lower end of the street lamp and a hole is formed in the plate to correspond to the anchor bolt. The anchor bolt is inserted into the hole of the plate, and the nut is fastened to fix it perpendicularly to the ground.

The street light includes a light source. The light source is formed by arranging one or more LEDs on a PCB substrate. The LED is preferably composed of a power LED so as to irradiate a wide light control area. In general, the power LED emits light and simultaneously generates heat. To this end, the PCB substrate is added to form a heat radiating means. The heat dissipation means may be installed to protrude integrally with the body on the outside of the street lamp so that the cooling fins are additionally installed to generate sufficient heat from the cooling fins.

If necessary for cooling efficiency, a heat absorbing plate may be added to and installed on the PCB, and a heat pipe may be additionally installed to quickly transfer heat absorbed from the heat absorbing plate to the heat radiating fins. Rapid heat dissipation can increase the lifetime of the LED formed on the PCB substrate.

On the other hand, an arm is formed between the street lamp and the street lamp. The arm is formed in the shape of a cylinder or a polygonal column forming a space empty inside, similar to a street lamp. The empty space is provided with a power cable for supplying power to the LED. The arm is coupled to one side of the upper end of the street lamp. To determine the dimming area, it is made by the street lamp pole, the arm, and the angle of the street lamp. In general, as disclosed in the prior art, after determining the angle of the street lamp and the arm, it is preferable to add a means for adjusting the angle between the arm and the street lamp to be able to adjust.

On the other hand, the street lamp according to an embodiment of the present invention is a heat dissipation fin protruding on the upper side and the body is provided with a receiving portion on the lower side, a PCB substrate having one or more light sources installed in the receiving portion of the body and the body It is configured to include a transparent cover coupled to the lower side of the.

On the other hand, in order to be combined with the arm and the street light, the body of the street light is formed with an arm hole into which the arm can be fitted. One end of the arm is fixedly coupled to the street lamp, and the other end of the arm is fixed to the arm hole formed in the street light. Here, the inside of the street lamp is provided with an angle adjusting unit for adjusting the angle of the combination of the street lamp and the arm.

Inside the body of the street light, as shown in Figure 2, the angle adjusting portion for adjusting the coupling angle between the street light and the arm is formed. The angle adjusting portion is composed of a stepped stepped portion and a flow preventing portion for supporting the arm.

The stepped portion is a stepped cross section when viewed from the side. In addition, the stepped portion, as shown in Figure 2, is formed in a pair of the same shape spaced apart a predetermined distance. The separation distance is preferably designed to be shorter than the diameter of the arm. After the arm is inserted into the arm hole formed in the body, the end of the arm is curved, so that it must be able to support the cross section of the curved surface in order to maintain a desired angle in contact with one step surface of the stepped portion. Therefore, if the separation distance is formed beyond the diameter of the arm it is impossible to the surface contact with the stepped surface of the stepped portion. More preferably, the spacing is formed below the radius. Here 'below' does not contain a zero, it is sufficient enough to support the arm.

Meanwhile, the stepped portion may be formed as one stepped portion. The one step must have a large area of the step in contact with the arm. At this time, it is preferable that the stepped surface of the stepped portion that the arm is in surface contact has a circular shape having the same shape as the circumference of the arm. If the supporting surface of the stepped portion and the supporting surface of the arm are the same, the support fixing can be made clearly.

The worker installing the street lamp is coupled to the arm by inserting the street lamp in the state in which the fixed street lamp column is fixed to the ground. One end of the arm is inserted into an arm hole formed in the body of the street light, and inserted into an appropriate length to be supported by any one step surface 222 of the stepped portion 221. In this case, the street light may support the arm by a load, but may flow by an external environment such as rain or wind. The flow may cause the street lamp to deviate from the street lamp column. As such, a first flow preventing part 223 is installed between the stepped portion and the arm hole to prevent the street lamp from being separated by the flow.

The first flow preventing part includes a hinge bolt 224 formed on the body and a hinge fixing part 225 fixing the arm. The hinge bolt is coupled by a shaft to be rotatable in the body. The hinge fixing part is formed with a hole into which the hinge bolt can be fitted. After the arm is fixed in position, it is inserted into a hole formed in the hinge fixing portion to the hinge bolt, and then the hinge bolt and the nut are rotated to securely fix the arm.

If the hinge bolt is not configured, the angle at which the stepped portion and the arm are coupled may be different, and thus the surface where the arm and the hinge fixing portion are in surface contact may not coincide. When the imaginary line formed by the rotation of the hinge bolt and the outer surface of the arm are perpendicular to each other, the hinge fixing portion and the arm can be in exact surface contact. By contacting the surface, the arm can be firmly coupled to the body of the street light.

Meanwhile, in order to couple the arm and the street light, a second flow preventing part may be further formed between a portion where the arm hole of the body is formed, that is, the flow preventing part and the arm hole. The second flow preventing portion is composed of a position fixing portion screwed with the body and a position contact portion coupled with the position fixing portion and in contact with the outer periphery of the arm. The second flow preventing part is not formed with a hinge. Therefore, the position contact portion may be in contact with the arm portion according to the angle.

4A to 4D are diagrams illustrating a combination of a street light and an arm according to an embodiment of the present invention. The street lamps are coupled at different angles relative to the arm. 4A is a diagram illustrating a case where an angle formed by an arm and a street light is 5 degrees. As shown in Fig. 4A, the arm end is in surface contact with a step surface that is formed to float away from the top surface of the stepped portion, that is, the inner surface of the body portion. Therefore, the dimming area emitted from the street light can be irradiated with the area relatively far from the street light.

4B is an arm combined with the step surface of the upper part of a stepped part. As seen from the side, the arm and the street light are horizontal to each other, so that the light output direction is perpendicular to each other. At this time, the dimming area is irradiated to the area centered vertically below the street light.

On the other hand, as shown in Figure 4c and 4d, the illumination area that can be irradiated by the street light may be irradiated inward from below the vertical of the street light. At this time, the arm and the stepped portion contact the lower stepped surface or the lowest stepped surface of the stepped portion. 4 (c) shows the case where the angle between the arm and the street light is -5 degrees, and FIG. 4 (d) shows -10 degrees.

As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention.
