The core technology of LED lighting mainly includes epitaxial growth control of the structure, chip design and manufacturing process, etc. The core technology is monopolized by a few large enterprises overseas and protected by their own patents. The development of LED courtyard lighting technology in China is very passive, and the courtyard lighting products have been uniform and low-level for a long time, leading to a vicious competition situation.

The basic function of the lamp itself is to provide electrical connection with the light source, and in general, the most important concern for users is whether this lamp can illuminate the place we want it to illuminate and whether it makes us feel comfortable; However, for professional lighting designers, in addition to being familiar with the material selection, lenses, and reflective systems of various lamp bodies, it is also necessary to understand the quality of the light spot projected by the lamp based on its light distribution curve, calculate the efficiency of the lamp and the illuminance value of any point in the space, and thus calculate the illuminance distribution in the spatial area. It is not an exaggeration to say that the light distribution curve of a lamp is the lifeline of the lamp.
