LED lens is mainly used for the protection of high-power LED lamp beads and has specific optical effect. Then, the reliability analysis of two kinds of glues for bonding and packaging lens is made as follows: (U # Z: R3 E3 W4 ^) @ "K"4 e: e- |" G$ N4 F0 C; K, i) ]( Q% J/ U9 x8 d& P" u! j/ xUV Lens adhesive: fast curing speed, high production efficiency. @* g7 n6 G, U                       Curing effect is general, thrust 15-25kg, pull 10-15kg) l - h8c! d, B$ E/ v$ U8 H                      Fast performance degradation, (self understanding) 2 A0 H0 a    v3 j5 b$ u9 B; Z+ |8 z! y% @( T    o1 A# i2 eThermosetting lens adhesive: strong adhesive force, thrust 20-40kg, pull 15-20kg + L: K8 S8 ', i                      Good thixotropy    z$ r7 B; W: b2 F; Z) F                      Small change of performance attenuation7 I4 F' W) N4 u' Q: p, [0 I                       Low efficiency - P3 o "~. \ - F & n) z4 P1 T: k5 y! g3 A, p8 ~    v. o1 F; @) v& S!

All of these were analyzed for reliability. However, the adhesive strength of the glue was good at that time. If the performance degradation was very serious, it would fall off automatically in a few months. An insignificant tiny node would affect a complete TV, so please ask the Technology Department of each major manufacturer, The Technology Department of each processing plant should take this problem seriously and try to use thermosetting glue as much as possible. The cost of glue can be ignored, so don't be greedy_ 0 a+ [! x.
