  According to the second embodiment, since the terminal block 160 is attached to the notch 150g of the substrate support member 150, the terminal block 160 is located above the substrate support member 150 (see FIG. 18 and FIG. 21). In this state, the distance between the LED unit substrate 130 and the translucent cover 120 attached to the power supply shielding member 120 is increased. For this reason, it is possible to prevent or reduce the state in which the LED elements 130f mounted on the LED unit substrate 130 are projected in a granular shape on the translucent cover 120, and a beautiful light emitting surface can be obtained.

  Further, by making the power source shielding member 120 made of polycarbonate resin, the insulation can be improved and the material cost can be reduced. Moreover, by forming the mortar-shaped light reflecting surface on the power supply unit shielding member 120, the LED irradiation light can be uniformly reflected over a wide range. Further, since the terminal block 160 is disposed in the cut-out opening portion 150g of the board support member 150, the mounting area of the LED elements 130f of the LED unit board 130 is reduced and the LED elements 130f are densely mounted. The LED irradiation efficiency can be increased in combination with the mortar-shaped light reflecting surface of the part shielding member 120.

  In the present embodiment, the shape of the LED lamp main body 2 is a cylindrical shape, but is not limited thereto, and may be a flat polygonal column having a quadrangular cross section.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to these embodiment, Even if there is a design change of the range which does not deviate from the summary of this invention, it is included in this invention. That is, various changes and modifications that can be made by those skilled in the art are also included in the present invention.

The terminal block 160 is inserted into the notch 150g of the substrate support member 150, and is attached to the substrate support member 150 by engaging the locking projection 160a of the terminal block 150g into the engagement hole of the upright piece 150h. An external power supply wire is connected to the terminal block 160, a connection port with the external power supply wire is directed to the external power supply wire insertion hole 2c of the mounting plate 2, and the power supply section of the terminal block 160 and the LED unit board 130 It is the same as that of the first embodiment that the connection port of the power supply wire that conducts is provided.

  As shown in FIG. 17, the LED lamp main body 100 described above is integrated by superimposing the substrate support member 150, the insulating cover 140, and the LED unit substrate 130 and fixing them with screws (not shown) or the like. As shown in FIGS. 15 and 16, the power source shielding member 120 is fixed or locked to the substrate support member 150 by means such as screws and locking mechanisms. FIG. 20 shows the mounting state of the mounting plate 2 and the LED lamp body 100 with the housing 10 removed. The mounting method of the mounting plate 2 and the LED lamp body 100, the connection between the terminal block 160 and the external power supply wire. Since the procedure and the like are the same as those in the first embodiment, the description thereof is omitted here.

  According to the second embodiment, since the terminal block 160 is attached to the notch 150g of the substrate support member 150, the terminal block 160 is located above the substrate support member 150 (see FIG. 18 and FIG. 21). In this state, the distance between the LED unit substrate 130 and the translucent cover 120 attached to the power supply shielding member 120 is increased. For this reason, it is possible to prevent or reduce the state in which the LED elements 130f mounted on the LED unit substrate 130 are projected in a granular shape on the translucent cover 120, and a beautiful light emitting surface can be obtained.

  Further, by making the power source shielding member 120 made of polycarbonate resin, the insulation can be improved and the material cost can be reduced. Moreover, by forming the mortar-shaped light reflecting surface on the power supply unit shielding member 120, the LED irradiation light can be uniformly reflected over a wide range. Further, since the terminal block 160 is disposed in the cut-out opening portion 150g of the board support member 150, the mounting area of the LED elements 130f of the LED unit board 130 is reduced and the LED elements 130f are densely mounted. The LED irradiation efficiency can be increased in combination with the mortar-shaped light reflecting surface of the part shielding member 120.

  In the present embodiment, the shape of the LED lamp main body 2 is a cylindrical shape, but is not limited thereto, and may be a flat polygonal column having a quadrangular cross section.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to these embodiment, Even if there is a design change of the range which does not deviate from the summary of this invention, it is included in this invention. That is, various changes and modifications that can be made by those skilled in the art are also included in the present invention.
