Abstract

The utility model provides an energy saving and high effective high voltage sodium lamp electronic ballast, which is characterized in that a DC high voltage transformer with a DC-blocking capacitor and a thermistor is arranged to ensure that the electronic ballast has long lifetime, less energy consumption, high quality and low cost. The electronic ballast not only prolongs the lifetime of a lamp bulb of a sodium lamp, but also increases the illumination effect.

Description

A kind of electronic ballast of high voltage sodium lamp of efficient energy-saving

The utility model relates to the electronic ballast of high voltage sodium lamp of a kind of electric ballast, particularly a kind of efficient energy-saving.

In the prior art, the integrated high-efficiency electricity-saving lamp is found everywhere, and it is the combination of electric ballast and three look compact fluorescent lamp tubes.But seldom see the electric ballast of high-pressure sodium lamp, this is because the power of high-pressure sodium lamp is bigger, the triggering starting resistor is higher, even if adopt corresponding power, high trigger voltage, low-voltage fluorescence lamp electronic ballast with tens of khz frequencies comes high frequency burning-point high-pressure sodium lamp, also can produce the unsettled what is called of electrical discharge arc " acoustic resonance " phenomenon, and can produce, the violent situation of forgetting oneself that increases of electric current along with voltage rises, cause ballast to disappear and ruin, the situation that fluorescent tube degenerates takes place.This pulsation exchanges the starting starter, and poor reliability is fragile, is difficult for repeating starter.

The purpose of this utility model is intended to avoid the deficiencies in the prior art and provides a kind of life-span long, the electronic ballast of high voltage sodium lamp of low energy consumption, high effect.

The purpose of this utility model is achieved in that

A kind of electronic ballast of high voltage sodium lamp of efficient energy-saving, comprise that appearance has the shell (5) and the inner element wiring board (1) of several parallel folding bars, the capacitance C1 (2) that it is characterized in that interior arrangement joins through the elementary T1 of thermistor RT and high direct voltage transformer T (3), the secondary T2 of the other end of capacitance C1 and high-tension transformer T joins, and is connected with sodium vapor lamp behind resonance and filter capacitor C2 through high voltage direct current that T2 induces.

---the capacity of described capacitance C1 is effective at 0.1 μ F～10 μ F.

The utility model is described in further detail below by drawings and Examples:

Fig. 1 is the utility model profile stereogram

Fig. 2 is the utility model structural representation, and wherein 1 is the element wiring board, and 2 is capacitance, and 3 is the high direct voltage transformer, and 4 is binding post, and 5 is shell

Fig. 3 is the utility model circuit theory diagrams, and wherein A, B are input, and C1 is a capacitance, and C2 is a resonator, filter electric capacity, and RT is a thermistor, and T is the high direct voltage transformer, and T1 is a primary, and T2 is a transformer secondary output.

The high-frequency current of the utility model output, induces high voltage direct current through T2 and exports sodium vapor lamp to the elementary T1 of transformer through C1 and RT, make its starter, and then electric ballast provides the electric current of lighting, and sodium vapor lamp gets final product normal ignition, after sodium vapor lamp is lighted, and the high direct voltage disappearance.

The utility model life-span is long, low energy consumption, and the performances such as waterproof are compared with inductance type ballast , economize on electricity reaches 20%, and is no more than for 5 seconds start-up time, prevents any greater than work The surge current of electric current impacts the sodium vapor lamp negative electrode, thereby has prolonged the life-span of bulb.
