PROBLEM TO BE SOLVED: To provide a rotatable LED illumination device which, in a situation where LED illumination fixture units are rapidly growing popular as an illumination energy saving measure, can help various makers which need to develop and sell many types of new products in a short period of time because of the rapid technical development of the LED illumination fixture units, avoid developing, producing and selling various types of similar LED illumination fixture units most suitable for various markets and uses, and prevent production costs from increasing because of huge development costs and impossibility of production with large production lots; and which can help a customer select the LED illumination fixture units in an easier way.SOLUTION: Low power LED illumination fixture units of the same specification or a plurality of specifications which are rotatably mounted to unit bases are developed, and by connecting and integrating them, an LED illumination device having required fixture light fluxes, light colors and light distributions can be configured easily and inexpensively. Therefore, development costs, product costs, and logistics costs of the makers are reduced and a customer can easily select the LED illumination fixture. |
