Multicolored led lighting method and apparatus

[Subject] The light of the color which can be chosen is offered using a light source like LED. [Solution means] The current controller for a lighting assembly object is indicated. The lighting assembly object may be an LED lighting assembly object. The current controller may be the current controller ("PWM") by which Pulse Density Modulation was carried out, or a current controller of other forms, and in there, each unit by which current control was carried out can be addressed peculiar, and can receive the lighting sexual desire news on a computer lighting network. In one enforcement form, the binary tree network composition of a lighting unit (node) is included. In another enforcement form, in order to accommodate a lighting assembly object, it has the heat diffusion housing made from a thermally conductive material. A heat diffusion housing contains two accumulated circuit boards which holds a power module and an optical module, respectively. The optical module conforms so that it may be exchanged with other optical modules and sufficient convenience. [Selection figure] Fig. 2
