Similarly to the heat radiating plate 2, the heat radiating fin 5 is composed of a flat plate-like substrate 6 having excellent heat conductivity in aluminum or the like, and a plurality of parallel fins 7 integrally formed on the substrate 6. The heat sink 2 is fixed integrally with the heat sink 2 in close contact with the plate 2.

  As shown in FIG. 4, the street lamp 30 includes a screw-type socket 31 for connecting to a light source such as a mercury lamp, a reflecting plate 32 that reflects the irradiation light of the mercury lamp, and a translucent cover 33 that covers the mercury lamp. It consists of. Further, as shown in FIG. 6, the socket 31 has a screw-type contact 34 and a bottom contact 35 on the inner peripheral surface thereof, and the power feeding portion 15 formed at one end of the heat radiating plate 2 is connected to the socket 31. The power source of the LED 10 is obtained by being inserted into the socket 31 of the street light 30.

  The power feeding portion 15 is provided at a cylindrical portion 16 protruding from one end of the heat radiating plate 2, a plurality of flexible terminal pieces 17 provided on the outer periphery of the cylindrical portion 16, and a bottom portion of the cylindrical portion 16. And the contact portion 18. The cylindrical portion 16 has a smaller diameter than the inner diameter of the socket 31, and when the cylindrical portion 16 is inserted into the socket 31, the terminal piece 17 is elastically deformed along the concavo-convex portion of the screw-type contact 34, and the elastic restoring force In a state where the terminal piece 17 is pressed against and contacted with the screw-type contact 34, the contact portion 18 provided at the bottom of the cylindrical portion 16 contacts the bottom contact 35 of the socket 31, thereby supplying power to the LED 10.

  Moreover, the LED illumination lamp 1 of a present Example has shown 120W-140W use, and the radiation fin 5 used for this LED illumination lamp 1 combines four radiation fins 5 of the same shape as shown in FIG. ing. In this way, by forming a plurality of radiating fins 5 having the same shape and combining the radiating fins 5 according to the size of the LED illuminating lamp 1, for example, as shown in FIG. The number of LEDs 10 is large, and the size of the heat radiating plate 2 is also increased. However, the heat radiation fins 5 having the same shape can be used for the 120 W to 140 W LED lighting lamp 1 and the 180 W LED lighting lamp 1A. The parts can be shared, and the versatility is excellent. In addition, as shown in FIG. 7, in addition to combining the common radiating fins 5 and attaching them to the respective LED illuminating lamps 1 or 1A, for example, in the LED illuminating lamp 1 for 120W to 140W, The heat radiating fins 5A may be formed according to the shape. Thus, if the elliptical heat radiating fin 5A is formed according to the shape of the heat radiating plate 2, heat can be radiated more efficiently.

  In the present embodiment configured as described above, a procedure for mounting the LED lighting lamp 1 will be described.

  As shown in FIG. 4, the LED illuminating lamp 1 inserts the cylindrical portion 16 into the socket 31 of the street lamp 30 so that the LED 10 faces the reflecting plate 32. At this time, each terminal piece 17 is elastically deformed along the concavo-convex portion of the screw-type contact 34, and the terminal piece 17 elastically presses the screw-type contact 34 by the elastic restoring force of each terminal piece 17. The posture is maintained in a state where the LED 10 of the lamp 1 is directed toward the reflecting plate 32 side. In addition, as a power supply of the LED lighting lamp 1, it is good also as a power supply by incorporating a direct-current power supply separately in the support | pillar (not shown) of the street lamp 30. FIG. Even in this case, the socket 30 uses the existing street light 30 as it is.

  As described above, in the present embodiment, it is possible to easily change to an LED simply by replacing the mercury lamp of the existing street lamp 30 with the LED illumination lamp 1, which can contribute to power saving. Further, the terminal piece 17 of the LED lighting lamp 1 is brought into contact with the screw-type contact 34 of the socket 31 only by pushing the power feeding section 15 of the LED lighting lamp 1 into the socket 31 of the street lamp 30, and the contact section 18 is further connected to the socket 31. The LED 10 can be powered by contacting the bottom contact 35 of the LED 10. At this time, it is necessary to hold the LED 10 provided on one side of the flat heat sink 2 in a state facing the reflecting plate 32 of the street lamp 30, while the existing street lamp 30 is a socket having a screw-type contact 34. 31 is adopted, the conventional screw-type base cannot accurately position the LED 10 of the heat sink toward the reflecting plate 32 of the street lamp 31 at the screwing end position. The terminal pieces 17 are elastically deformed along the unevenness of the screw-type contact 34 of the socket 31, and each terminal piece 17 is caused by the elastic force of the terminal piece 17 itself with the contact portion 18 in contact with the bottom contact 35 of the socket 31. The LED lamp 1 is held in pressure contact with the screw-type contact 34 of the socket 31. That is, it is only necessary to push the power feeding portion 15 of the LED lighting lamp 1 into the socket 30 with the LED 10 provided on one side of the heat radiating plate 5 facing the reflecting plate 32 of the street lamp 30. Thus, by deforming each terminal piece 17 and connecting the LED illumination lamp 1 to the socket 31 so as to push the power feeding portion 15 into the socket 30, the attitude of the LED illumination lamp 1 is maintained, and it is easy and reliable. The LED 10 can be held in a state where the LED 10 is directed to the reflector 32 of the street light 30. The LED lamp 1 inserted and held in the socket 30 is appropriately provided with a fixing bolt or a fixing wire in a fixing hole 8 formed in the outer end portion of the LED lighting lamp 1 as required (not shown). If it is made to fix to the street lamp 30 through, it can fix more stably.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to the said Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, the shape of the heat radiating plate and the terminal piece or the configuration of the street light may be selected as appropriate.
