What are the first and two optical designs of LED?

Introduction: high power LED lighting components in the lighting products before the general two optical design

High power LED lighting components in a lighting product, generally two times the optical design: an optical design is the design of LEDIC encapsulation LED optoelectronic components, in order to solve the LED light angle, light intensity, luminous flux, color temperature, light intensity distribution scope and distribution; two optical design is through a lens light through an optical lens changes its optical properties. The two optical design is for high-power LED lighting, the general high-power LED have a lens, the luminous angle of about 120 degrees

We must be soberly aware that optical design is the basis of the two optical design. Only a reasonable optical design package, to ensure the quality of light emitting components to each LED, two times optical design based on an optical design, to ensure the quality of the light emitting system. Simply put, the purpose of the first optical design is to remove as much as possible the light emitted from the LED chip, the purpose of the two optical design is to make the entire lighting system to meet the design requirements of light energy.
