Why is the ballast of sodium lamp or metal halide lamp damaged frequently How to effectively reduce

Personally, I think there are two main factors that affect the life of the ballast:

First, the working voltage fluctuates greatly, and the commonly used 220V voltage fluctuates up and down by more than 10%, which has a fatal impact on the life of the ballast.

The second is the quality of the ballast purchased, on the surface the ballast is some silicon steel sheets and coils, the process is not complicated, in fact, the quality of each manufacturer is very different, not to mention some low-end goods directly use aluminum ballasts. It can also be found from the ** that a good ballast is a hundred, and the cheap one is only fifty or sixty yuan, and the quality difference is self-evident, here to explain, electronic ballasts and inductive ballasts, we commonly use inductive ballasts, electronic ballasts used in European standards, taking electronic ballasts produced by Osram as an example, the retail price of 150 watts is about three hundred yuan, and the other is that electronic ballasts need to be equipped with a special light source, which is more troublesome to buy.

Finally, I would like to remind you that all the "well-known" brands such as Philips and Yaming should not be fooled, they are all imitations, and all good things will become garbage goods in China.

It won't be an aluminum wire, but an electronic one.

1.Ballasts are generally placed in sealed lamps, and attention should be paid to heat dissipation, especially for high-power ones.

2.The ballast material, don't use the aluminum core, it's cheap to buy and expensive to use.

3.Compensate capacitance.

4.Connect the circuit breaker or fuse.

Not easy to break the advantages.

1) Small size, light weight, average trouble-free time up to 35000h.

2) When the voltage of the power grid fluctuates, the output power is guaranteed to be constant, and the light is stable and flicker-free, and the life of the bulb is extended by 20%.

3) Using PFC correction technology, the current waveform is pure sine wave and has no impact on the power grid, and green lighting is realized.

4) The power factor (PFC) is as high as above, and the input current is half smaller than that of traditional inductor ballasts.

5) The efficiency is more than 94%, and the energy-saving effect is significantly more than 10%.

6) The working voltage range is wide, AC160V-264V, and can work normally.

Generally not easy to break, but also to extend the life of the bulb, the brand has a free warranty period of 1 2.

I recently learned about a, Hunan Siiico Dingsheng Electronic Technology **** launched the XLDS series of high-pressure sodium lamp electronic ballast, it is 3 years free of charge, since it can say such a quality assurance, it proves that it is very confident in its own products.
