2.3. The light intensity analysis of the LED system
The photoelectric parameters of the LED supplementary lighting system with red blue ratio of about 4:1 was test by the integrating sphere. The results obtained are shown in Fig. 6 .

As it can be seen from Fig. 6 that the ratio of intensity for the red LED and blue LED is about 4:1. The wavelength of the red LED is mainly at about 650 nm and that of the blue LED is mainly at about 460 nm. It just meets out expectations. The major photometric parameters of the supplementary lighting system is listed in Table 4.
