7.5. The brightness values are measures of the lamp surface brightness. The transmitted light through the
LCD is approximately 8% of the lamp surface brightness.
7.4
Electromagnetic Interference (EMI)
Electroluminescent lamps have been shown to radiate negligible interference through UHF when operated by
quasi–sinusoidal waveforms.
7.5
DC–AC Inverter
Optimum performance and life can be achieved by using the inverter P/N 46013–01. The inverter extends; the
useful life of the lamp by compensating for the aging characteristics of the lamp. The inverter operates in a
constant power mode which provides for long lifetime at a relative constant light output. Because of the quasi–
sinusoidal output, RFI is minimal and usually no shielding is required.
