China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

LED Flood Light, which includes radiator, base, LED light source, reflector, glass, reflective glass mounted on the substrate side, LED light source disposed in reflective glass focus on the outer layer is covered with a glass reflector the radiator has a plurality of cooling fins, fin curved distributed in the other side of the substrate. The utility model uses curved fin distribution, increasing the heat dissipation area to speed up the cooling rate.

LED floodlight driving device and driving method, including micro-controller, dual half-bridge driver, the stepping motor; said microcontroller with a double half-bridge output terminal connected to the input drive, said dual half-bridge driver the output terminal connected to the input of the stepper motor, the driving device which is characterized by a dual half-bridge driver input directly to the stepper motor. LED floodlight driving device of the present invention and its driving method that is driven by a dual half-bridge direct amplification of the PWM pulse signal to drive the stepper motor rotates, no jitter and noise.
