- the support column 2 is formed by sheet metal processing of a stainless steel plate having a thickness of 2 mm, the weight of the lighting device 1 is about 60 kg, and about two workers are required to perform the operation manually. Easy loading and installation are possible.
- a hole with a depth of lm or more is dug at the installation location of the lighting device 1, and a broken stone, a chestnut stone, or the like is provided on the bottom surface of the hole.
- the support 2 is put into the hole, the support 2 is erected using an auxiliary hook, etc., the concrete is poured into the hole, and the concrete surface is set to be substantially flush with the position of the base plate 11 of the support 2. Level. In this state, after the concrete is hardened, the auxiliary sticks are removed.
- the storage batteries 6 and the charge / discharge unit 7 are accommodated in the column 2, connected to wiring, and the rear plate 2 e is attached to the rear of the column 2 and screwed.
- the lighting device 1 can be installed by only about two workers without using heavy construction equipment such as a crane truck or an excavator truck.
- the lighting device 1 can be installed even in areas without roads where heavy construction equipment cannot enter or areas with steep slopes.
- it is unnecessary to restrict traffic during the installation work and to arrange guards.
- the column 2 is in the shape of a quadrangular column, the rotation of the column 2 due to a typhoon or a strong wind is prohibited by the solidified concrete. For this reason, a special structure for stopping the rotation of the column 2 is not required.
- the embodiments of the present invention are not limited to the above-described embodiments, and can be variously modified.
- the number and arrangement of each LED lamp and the number and arrangement of each LED of the LED lamp may be appropriately changed.
- a structure in which the illumination directions of the main illumination section 3 and the sub illumination section 4 can be appropriately changed or adjusted may be adopted.
- various types of light sources may be employed as the main lighting unit 3 instead of the LED lamp.
- a combination of another type of light source and a reflector may be used as the sub-illumination unit 4 so that the sub-illumination unit 4 has directivity.
- the colors of the irradiation light of the main lighting unit 3 and the sub-lighting unit 4 may be different from each other.
- a power supply that can combine solar cells and a storage battery and a commercial AC power supply may be selectively used, or only a commercial AC power supply may be used.
- the lighting device of the present invention is suitable for night lighting such as street lights, night lights in gardens and premises. In addition, it is not just a mere light, but a guide light, security light, emergency It can also be used for lighting.
