Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment in which a bifurcated mounting bracket 2 is fixed to an upper portion of a support column 1 and the LED lighting lamp 5 according to the present invention is supported on the mounting bracket via screws 3 and 4 to be used as a street lamp. 2 is a sectional view taken along line AA, FIG. 3 is a sectional view taken along line BB, and FIG. 4 is a sectional view taken along line CC. The direction of the LED illumination lamp 5 can be adjusted by loosening the screws 4.

As shown in FIG. 5, the housing 6 of the LED lighting lamp 5 has a frame-like cover body 8 attached to a substantially rectangular plate-like base body 7 and a light-transmitting property in the front opening 8 a of the cover body. The acrylic plate 9 is stretched. Reference numeral 8a denotes a screw for fixing the base body 7 and the cover body 8 together. A support plate 7a standing in a mountain shape is protrusively provided near both end edges of the inner surface of the base body 7, and arc-shaped long holes 7b are formed in the support plate 7a at appropriate intervals. In addition, 7c is a round hole for electric wire penetration.

Reference numeral 10 denotes a mounting plate made of a mold material formed into an equal cross section having a substantially U-shaped cross section by extrusion molding of aluminum, and the mounting plate has a round shaft on one side edge as shown in FIG. A joint portion 10a is formed, and a notched annular joint portion 10b that can be loosely fitted on the outer periphery of the joint portion 10a is formed on the other side edge so as to face the inside of the joint portion 10a and the joint portion 10b. Groove-shaped rail portions 10c and 10d are formed. Reference numeral 12 denotes a wiring board on which a plurality of LED elements 11 are mounted. By sliding the wiring board 12 from one end of the mounting plate 10 into the grooved rail portions 10c and 10d, the wiring board 12 is attached to the mounting plate. It is designed to be attached to the front. In addition, 10e is a recessed part formed in the front surface of this attachment plate so that the electric wire connector 12a protrudingly provided by the back surface of this attachment plate may be accommodated. Reference numeral 10f denotes a vertical groove formed so as to be adjacent to the recess, and a screw 13 is inserted into the wiring board 12 to prevent the wiring board 12 from sliding unnecessarily. It can be screwed into the groove 10f. Reference numeral 10g denotes a notched circular lateral groove formed in a substantially middle portion on the outer side (back side) of the mounting plate, and a screw 14 described later can be screwed into the lateral groove. For this reason, the mounting plate 10 is arranged in parallel with a plurality of the same shape, and the adjacent joints 10a and 10b are connected to each other so that they can be refracted at the joints. It becomes possible to do. In addition, by making the outer diameter of the joint part 10a slightly larger than the inner diameter of the joint part 10b, resistance can be appropriately obtained during refraction, and the refraction angle can be kept constant.

In this LED illuminating lamp, three mounting plates 10 are symmetrically arranged in parallel on both sides of the connecting plate 15 in the middle so that the connecting plate 15 has a mountain shape with the connecting plate 15 at the apex. The connecting plate 15 has a transverse cross section bent in an orthogonal shape, and joint portions 15a and 15b are formed on both side edges, and the joint portions 10a and 10b of the mounting plate 10 are loosely fitted to the joint portions 15a and 15b, respectively. ing. The mounting plates 10 are fixed in this state by inserting screws 14 into the long holes 7b of the support plate 7a and screwing the screws 14 into the lateral grooves 10g. For this reason, each mounting plate 10 is adjusted to a desired refraction angle with respect to the adjacent mounting plate, and the screw 14 is moved in the elongated hole 7b accordingly, and the screw 14 is screwed into the lateral groove 10g. The angle of refraction can be fixed, whereby the irradiation direction of light emitted from the LED elements 11 provided on each wiring board 12 can be finely adjusted to a desired direction in accordance with a request from the installation site of the LED illumination lamp.
