The above-mentioned instrument body is a molding material which is open at both ends with a substantially the same continuous cross section by aluminum extrusion or aluminum die-casting provided with a front thin part, a rotating bearing part, and a heat radiation fin cover thin part, and is usually integrally molded. The

The fixture body of a general LED lighting fixture is often molded by aluminum die casting in order to also serve as a heat radiating member for efficiently conducting and radiating the heat generated by the LED light emitting part. However, ordinary aluminum die-casting has the disadvantages that although the degree of freedom in shape design is high, the die cost is high, small-lot production is difficult, and the unit cost is high.
Aluminum extrusion molding materials are limited in maximum outer diameter and cross-sectional shape, but they have the advantages of low mold costs and low part costs, ease of small-lot production, and the length in the extrusion direction can be set freely. The rotating bearing and the like are integrally molded as follows, and the integrally molded material is cut to a predetermined size to manufacture the LED lighting unit unit body at a low cost.
Aluminum die-cast molding material has a cross-sectional change equivalent to the draft of the mold, but using a continuous molding material with almost the same cross-section makes the mold cost relatively low and does not require cutting after molding. Depending on the production lot, the unit price is also low. If a tool body is configured by connecting a plurality of molding materials, the length of the molding material can be changed, and the mold cost can be reduced.

It is a thin part with fins. The plane of the front thin part may be a single plane, but if it is a multiple plane with a plurality of planes, the light distribution of the LED luminaire unit can be expanded.
Fixing each component of the LED light emitting unit is usually screwed, but in the case of outdoor lighting fixtures, the screw hole is not penetrated through the screwed part of the thin part rather than screwed after applying the sealing material to the screw part. It is better to completely block the intrusion of external moisture from the screwing portion as a thick wall.
The thin part for the heat dissipation fin cover covers the heat dissipation fin, prevents dust and oily smoke from accumulating on the heat dissipation fin, accumulation of bird droppings, securing a cooling air ventilation path, and flying objects.

Adjacent LED luminaire units may be in close contact with each other, or may be provided with a ventilation gap between end surfaces.
The rotating shaft may be a threaded shaft on both ends, and a predetermined number of LED luminaire units may be mounted, and after individually setting the irradiation direction, the LED luminaire units may be pressed together and fixed with a tightening nut at the end of the shaft.
