lamp + unconcentrated solar cell

assumption : 35 Watt x 38 lumen/W = 1330 lumen             ( 1330 W is the solar radiation constant per sqm ; attention : differ lumen and Watt )

1330 lumen x 0,0525 = +- 70 Watt ( 0,0525 for 5,25% solar cell efficiency in the end 80´)

lumen per Watt lamp to reflector concentrated solar electric DC Watt

[0005] 200 Watt/sqm indicates 15% solar cell use

lumen per average Watt DC lamp + DC power saver to solar electric DC Watt

lumen per average Watt + power saver to solar electric DC Watt

lumen per average Watt + power saver to solar electric DC Watt

about HF or HV generator use ,pulse power, lamp lifetime in-/de-crease :

The amplitude of the needle pulses fed to the load is limited by the presently available electronic circuit means for producing the pulses. With presently available electronic circuit means, pulse durations in the order of magnitude of 100 nanoseconds can be realized. Accordingly, very high voltages can be employed which are greater than the nominal voltage of the load by a factor in the range of one or two orders of magnitude.

With a direct current circuit, care must be taken that the supply voltage fed to the load is by no means substantially greater than the nominal voltage. However, it is known that there is an almost proportional relationship between the quotient of supply voltage and nominal voltage on the one hand and the efficiency of the consumer (=brightness of an incandescent bulb) and the useful life of the consumer on the other hand. For example, when a bulb with a nominal voltage of 100 volts is fed with a voltage of only 90 or even just 80 volts, the efficiency deteriorates, i.e. the light yield becomes clearly lower. However, with decreasing efficiency, the useful life increases at the same time. When the supply voltage is in the opposite manner increased to 110 or even 120 volts, the efficiency, i.e. in the present case the light yield, is improved, but the useful life deteriorates correspondingly. When the supply voltage is considerably higher than the nominal voltage, e.g. by a factor of 1.5, the load will be destroyed within a short period of time.

By the measure according to the invention, the useful life of the load is definitely not affected negatively, but rather is extended. Due to the fact that the needle pulses supplied to the load are of extremely short duration, the load is not destroyed, not even when the voltage of the pulses is by far higher than the nominal voltage of the load.
