Constant-current circuit apparatus of parallel led luminaires

A constant-current circuit apparatus of a parallel LED luminaire, comprising:

• An electrical connector unit of a parallel LED luminaire distributes DC power through its input unit to one or more of its constant-current LED light module units and through its output unit to the input unit of the succeeded parallel LED luminaire connected to it;
• A constant-current LED light module unit includes a current regulation unit and an LED light module unit connected in series;
• A LED light module unit includes one or more LED cluster unit connected in series;
• An LED cluster unit includes at least one LED component and a bypassing diode connected in parallel;
• An LED cluster unit emits the light through at least one LED components connected in parallel;
• A bypassing diode in an LED cluster is, used to ensure the continuous flow of the current throughout the LED light module unit
• A linear current regulator is used in the current regulation unit to restrict the current flow at a desired current value through the LED light module unit in a constant-current LED light module unit;
• A resistor is used to set the desired current value in the current regulation unit;
• A reverse-current diode is used to prevent the linear current regulator from being damaged by reverse current flow;
• Said parallel LED luminaire generates the light by restricting the current flow through one or more LED cluster unit in a series constant-current LED light module unit, where the LED cluster unit emits the light through at least one LED component connected in parallel.
