The most important thing about the LED lens light is the lens. The lens can make the light emitting angle larger, and the light is uniform without spots. The lens of the LED lens light includes a primary lens and a secondary lens. The secondary lens can make the light produce the desired effect. Specifically, details as following.

primary lens

a. The primary lens is directly encapsulated (or glued) on the LED lens lamp chip holder and integrated with the LED.

b. The chip of the LED lens light is theoretically emitting 360 degrees, but in fact, the chip can be fixed and packaged on the LED lens light bracket, so the maximum light-emitting angle of the chip is 180 degrees (there is also a small amount of excess in the range greater than 180 degrees). In addition, the chip will also have some stray light, so that all the light of the LED lens lamp can be effectively converged through one lens, and different types such as 180°, 160°, 140°, 120°, 90°, 60°, etc. can be obtained. The light-emitting angle is different, but the light-emitting efficiency of the LED lens lamp with different light-emitting angles has a certain difference (the general rule is: the larger the angle, the higher the efficiency).

c. The primary lens is generally made of PMMA, PC, optical glass, silica gel and other materials.

Secondary lens

a. The secondary lens and the LED module are two separate objects, but they are inseparable in application.

b. The function of the secondary lens is to refocus the light-emitting angle of the LED lens light source into any desired angle between 5° and 160°. The distribution of the light field can be mainly divided into: circle, ellipse, rectangle .

c. The secondary lens material is generally optical grade PMMA or PC; in special cases, glass can be selected
