The invention provides a flicker-free LED lamp. The lifting and rotating mechanism is composed of a rotating shaft, a mounting plate, a servo motor, a telescopic rod, a supporting sleeve rod, a casing, a fan, an air filter, a refrigeration plate and a lamp, and the upper end of the supporting sleeve rod is arranged There is a telescopic rod, a mounting plate is installed on the upper end of the telescopic rod, and a servo motor is installed on the front end of the two mounting plates, and the two mounting plates are symmetrically installed at the front and rear ends of the rotating shaft. Large lighting range, the air filter is installed on the right side of the fan, the cooling plate is installed on the right side of the air filter, and the lamp is installed on the right side of the cooling plate, and the fan, air filter and cooling plate are all installed inside the shell. To dissipate heat, the present invention can be rotated, the height can be adjusted, the lighting range can be increased, the weight can be reduced, the production cost can be reduced, and the heat dissipation effect is poor.
