Introduction to the LED optical design and the secondary optical design at a time

High power LED lighting components before he became a lighting products, generally must carry on the two optical design. LED IC assembly into the LED optoelectronic components, a first optical design, in order to solve the LED light Angle, light intensity, and the size of the luminous flux, luminous intensity distribution, the range of color temperature and distribution. This is known as an optical design. Secondary optical design for high power LED lighting: general high power leds have a lens, light Angle of 120 degrees or so. Secondary optics is to again after a lens, the light through an optical lens to change its optical properties.

we must be acutely aware that an optical design is the foundation of the secondary optical design. Only an optical design packaging design is reasonable, to ensure that each LED components of light quality, can in an optical design on the basis of the secondary optical design, to ensure that the entire light-emitting system of light quality. Say simply, an optical design as much as possible is the purpose of the light out LED chip. The purpose of the secondary optical design is to make the whole system of lamps and lanterns of light energy meet the design requirements.

the following basic structure for LED optical design, only supplies the reference:
