Background technique

As a new type of light source, LED lights have the advantages of high luminous efficiency, energy saving, and environmental protection. The LED floodlights used to brighten buildings are usually LED lights with ordinary lenses. In order to maximize the use of light energy, the existing LED floodlights use ordinary lenses, which have low light utilization efficiency, poor heat dissipation effect, poor waterproof effect, and no waterproof and breathable rosette to balance the internal and external pressure difference. Shorten the lamp life. Commonly used ordinary LED floodlights have poor light mixing and uneven light output due to the arrangement of single RGB lamp beads. In order to make the light output uniform, direct four-in-one chip packaging and optical devices are selected to achieve uniform light output. Therefore, it is necessary to improve its structure and design a dual-purpose square floodlight.
