Notes:
1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-response curve.
2. The dominant wavelength (λd) is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
Double Light which is a professional LED manufacturer mainly produce led components with automatic production lines,
which include THT LEDs, chip LEDs,7 segment led displays, infrared LEDs ,UV led and so on.
