LED, known as the fourth generation lighting source or green light source, is the most energy-efficient luminous body today. It has the characteristics of energy conservation, environmental protection, long service life, small size, and can be widely used in various fields such as indication, display, decoration, backlight, general lighting, and urban night scenery. As a global manufacturing base in the electronics industry, China has already accounted for half of the development of the global LED industry. It has formed a relatively complete industrial chain, including the production of LED epitaxial wafers, the preparation of LED chips, the packaging of LED chips, and the application of LED products.

Adhesives in LED lighting products mainly play a role in bonding, sealing, thermal conductivity, flame retardant protection, and other functions. The quality of the adhesive directly determines the safety and stability, atomization transparency, aging and durability of lighting products.
