LED High Bay Technologies to Be Improved (V)

      3. Secondary light distributionIn order to achieve better output beam of  led high bay    chips and utmost utilization of light, secondary optical design of LED Lights source is needed to satisfy design requirements. The main requirement for secondary optical design is to focus light on expected lighting areas. The basic components of current secondary optical design are lens and reflection cup. The major technical problems of secondary light distribution are how to improve uniformity of luminance, how to reduce uncomfortable glare, and how to achieve better light distribution and increased light utilization efficiency.
