OVIA ® | TECHNICAL SUMMARY

A device that accepts an input voltage and current and translates/transforms it to a different predetermined and controlled voltage and current. The resulting output then used to power or “drive” an LED circuit. 3DUDOOHO ZLULQJ PHDQV WKDW HDFK FRPSRQHQW KDV WKH VDPH VXSSO\ YROWDJH DQG DOO ÀWWLQJV RQ WKH FLUFXLW ZLOO have the same voltage across the luminaire terminals.

Today, manufacturers can produce white LED light with only a single chip. In luminescence conversion, only a blue LED is used, whose light stimulates a luminescent substance that emits yellow light, the system produces the colour white. Depending on the composition of the luminescent substance, various white tones can be achieved such as warm white, cool white etc.
