Abstract

The analysis of obtained results has shown, that at the moment occurrence of discharge in all types of HID, current exceeds the nominal value at least on 5% (for mercury arc lamp DRI 150) and maximum on 6 % (for mercury arc lamp DRL 400). Voltage on the contrary, lower from nominal in 5-10 times. During the transition process of brighten up, current decreases and the voltage increases, to the nominal values. The duration of the transition process of brighten up, is in the range between 4 and 10 minutes.
Experimentally there has been established, that among the existing types of high-pressure discharge lamps, type of sodium vapor lamp can only be recommended for use in regulatory schemes of luminous flux. This is
because in them: a) coefficient of luminous flux pulsations in the process of dimming decrease, by an average on 10% (for mercury arc lamp DRL – 9 %, for mercury arc lamp DRI – 22 %); b) the greatest multiplicity of dimming (average tenfold), the lamp DRI - three times, and the DRL - 2.5-fold; v) the lowest total power consumption of set-HID sodium vapor lamp electromagnetic ballast throttle in the mode of dimming maximum; g) the highest luminous efficiency; d) the greatest average duration of glow.
That has been confirmed, that for dimming of HID sodium vapor lamp, the best to use double-winding ballasts throttles. At startup of one winding, throttles has a nominal impedance and provides a nominal power of lamps. In a series, turn on of both windings throttles impedance increases. This leads to a decrease power of lamp. Such approach is the most economical. To use of electronic starting devices is impractical.
They are less reliable, significantly more expensive from electromagnetic and does not lead to increase of luminous efficacy and average duration of glow of HID. Ratio of dimming should not exceed of double value. In this
approach, luminous efficiency remained very high, providing 40% energy savings, and no essential changes color rendering and color temperature.
