The utility model relates to a heat-dissipation optimization and temperature on-line monitoring system for a light-emitting diode (LED) lamp. The heat-dissipation optimization and temperature on-line monitoring system for the LED lamp comprises LED arrays arranged in a nonuniform lighting arranging pattern with heat-dissipation optimized main chipsets, and a voltage-triggering comparison circuit for temperature on-line monitoring. According to the principle of natural thermal convection and the ideas of complying with maximum heat dissipating capacity and the optical design, a designed optimum arranging array of LED project lamp chipsets is center nested symmetrical array. When the temperature of the LED lamp is normal, an electrical level trigger can not be powered on and a buzzer can not alarm. When the temperature of LED project lamp chipset is above an alarming temperature, a voltage of an induced current produced when the electrical level trigger is powered on is above a reference voltage. A 5-volt direct voltage is output after a comparison module is triggered by the voltage to produce a rising edge and audion is triggered, an indictor light is lightened, and the buzzer is triggered at the same time. trigger an audion, lighten an indicator light, and trigger the buzzer at the same time. The heat-dissipation optimization and temperature on-line monitoring system for the LED lamp is high in reliability and low in cost, and achieves the idea of energy conservation and environment protection while meeting the quality requirement of durable use. The heat-dissipation optimization and temperature on-line monitoring system for the LED lamp can be widely used for lighting in the night for public leisure venues and used as a searchlight in the field of highway traffic.
