Some Measurements from experts about YUJILEDS Sunlight Technology LED
Delta optical thin film
Delta optical thin film focuses on complex optical filter technology for more than 50 years and it is one of the first companies to produce ultra-hard-coated optical filters. Today, the design and manufacture of high-performance fluorescence filters are the main business, and with the in-house design and production tools, Delta continues to meet the needs of discerning OEM customers.
During the evaluation of Yujileds® sunlight technology LEDs, Delta Linear Variable Bandpass Filters (LVVISBP) is applied for the measurement. The measurement procedure is as simple as putting the filters in front of the light sources, but the phenomenon is noticeable by naked eyes directly, especially when compared to a fluorescent lamp and standard LED. Spectrum theory sometimes is difficult to understand but this measurement perfectly explains the relationship between spectral and visual differences. Every detail in the spectrum could be presented in the result after the filters, and eventually the importance and value of a full-spectrum LED should be widely accepted.
