The lens of the LED lens lamp includes a primary lens and a secondary lens, the details are as follows.

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 (chip) of the LED lens lamp theoretically emits 360 degrees, but in fact, the chip can be fixed and packaged on the LED lens lamp bracket, so the maximum lighting angle of the chip is 180 degrees (more than 180 degrees There is also a small amount of excess In addition, the chip will also have some stray light, so that all the light of the LED lens lamp can be effectively gathered through one lens and can be obtained such as 180°, 160°, 140°, 120°, 90°, 60°, etc. However, there are certain differences in the light-emitting efficiency of LED lens lamps with different light-emitting angles (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
