Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to solid state lighting, particularly, the control of solid state light emitter fixtures. 
       BACKGROUND OF THE INVENTION 
       [0002]    The design and invention of general illumination lighting derived from electricity began in the late 1,800.s, and was popularized by inventors Tesla and Edison and commercialized by Westinghouse and General Electric. This original system provided for the distribution of alternating current and it&#39;s connection to a filament lamp controlled by a blade switch. This system has progressed over the last about 130 years, but in general still maintains the same basis of distributing alternating current over physical wires, with the expansion of control from a single switch to dimmers to highly connected digitally connected devices, and the filament lamp to many styles of light emitting devices. This core system is commonly referred to a “Legacy” system, and is referred to as such throughout this. 
         [0003]    The large proliferation of Legacy systems in building structures throughout the world has maintained, expanded, and continued adaption of lighting control and lighting fixtures to this Legacy standard even though solid state lighting is derived from direct current. The early adaptation of solid state lighting was the integration of a driver circuit, one to multiple light emitting diodes, and an alternating current (AC) to direct current (DC) conversion circuit tightly integrated in a Legacy type lamp, commonly called a LED lamp. Problems arose from this initial design. First, heat from the driver, AC to DC voltage conversion, and the Emitter caused a short life of the LED lamp. Second, the emitter color changed with age, mostly caused by the heat, Third, Legacy dimmers did not function because they did not work with the zero voltage crossing of AC and the reduced voltage at low lighting levels was below what the driver would output to the emitter. 
         [0004]    The next generation of solid state lighting into Legacy systems progressed with dimmers modified to address the voltage issues (and other technical improvements), and Legacy LED lamps with greater heat dissipating capacity but this just improved existing integration issues. 
         [0005]    A third generation of solid state lighting into Legacy systems progressed with placing control circuits inside of Legacy LED lamps. These systems are dependent on AC distribution and can have a control switch in the circuit, but primarily derive lighting lamp/fixture control through a communications path generally conforming to a published standard such as DALI, ZigBee, WiFi, DMX, Sub-1 Ghz, IEEE 802,xx, 0-10 volt, or other published proprietary format. Some of these controls are commonly found in stage and theatrical lighting systems or integrated into a centralized building automation communication system hub. Heat and other existing issues still exist. 
         [0006]    Today the fourth and current generation trend in the world is now toward the concept of the loT (Internet of Things), where every end product has a IP communications connection to the internet and interfaces to smartphone app&#39;s (application) for control, generally over WiFi, ZigBee, and/or Bluetooth. And heat and other existing issues still exist. Many inefficacies and redundancies exist in the current Legacy solid state lighting systems today. This invention addresses most of these, as an example is the concentration of a cumulative single source of heat derived from the integration of power conversion, control circuit, driver circuit and solid state lighting emitter(s) in a single enclosure and its continued thermal damage to the entire Legacy LED lamp. Other items addressed or eliminated fixture by this invention, by separating all components at the light are multiple points of voltage conversion in the system, basic elimination of AC to DC conversion, elimination of under and over AC voltage and voltage ripple, very high voltage spikes, DC isolation from dangerous AC current levels, flicker in dimming from AC injection in circuit, reduction in the complexity of driver circuit components, single source of user interface for control at traditional Legacy location, and EMI and rf reduction or elimination, 
       SUMMARY OF THE INVENTION 
       [0007]    The intended outcome benefits of this solid state lighting control device invention to a solid state lighting system in general are the elimination of centralized heat concentrations at each singular solid state lighting lamp, reduced wire sizes in the wiring distribution complexity and there installed wiring cost, creation of a singular centralized control point distribution location for solid state lighting drivers who&#39;s location is similar in use to traditional Legacy system locations, and to eliminate or isolate the dangers of AC power distribution to solid state emitter lighting fixtures. Additional intended outcomes of separating the heat conducting parts of a solid state lighting emitter from the solid state lighting control and driver circuitry are the reduction of the size and requirement of heat sinking at the solid state lighting emitters therefore extending the life of the solid state lighting emitters, plus as an additional benefit will be to provide for the reduction in size of the solid state lighting fixture housings or enclosures. Although there is only a small reduction in overall system heat the thermal isolation of components allows more natural cooling without highly designed engineering and connected thermal auxiliary cooling components.
