LED projection lamp is composed of three parts: optical part, mechanical part and electrical part. The optical components are mainly reflectors and light limiting grating. The mechanical components are mainly the shell, the focusing mechanism for fixing and adjusting the position of the light source, the bracket and base for fixing the lamp, and the parts with angle indication for adjusting the light beam projection direction of the lamp.
For most of the sealed led floodlights, the mechanical parts are protective glass and various sealing rings. According to the needs of the use environment, some are equipped with metal mesh covers. The LED projector with good performance is also equipped with air filter. The electrical components are ballast, capacitor, trigger, etc.
The LED projection lamp adopts the honeycomb structure design, the upper and lower through-hole heat dissipation structure, which can better heat dissipation, more security and better protection.
