Abstract
A single grain LED main lighting lamp of electric vehicles relates to a circuit control module, a constant-current driving module and an LED front lighting lamp, wherein the circuit control module is mainly formed through an electric quantity indicator and a voltage comparator, wherein the electric quantity indicator takes the voltage comparator as a core device, and displays the change of the electric quantity and the under-voltage indication through the lighting and the extinguishing of a light-emitting diode. The constant-current driving module is the driving module of the LED front lighting lamp, and takes the constant-current driving module as the core device. High voltage of a battery is connected to a power supply input end connected on the constant-current driving module after filtering and is reduced to low voltage from high voltage, and the voltage is supplied for the LED front lighting lamp. One end of the constant-current driving module is connected with an MOS pipe and an LED. The constant-current driving module adopts a PWM control chip, which can stably provide constant current for the LED front lighting lamp, and saves an amount of the energy consumption. The single grain LED main lighting lamp has simple integral structure and high reliability, and can be matched with various electric vehicles sold in existing markets.
