The utility model has the advantages of simple line, low cost, reliable operation and long service life.
Description
The utility model relates to a kind of illuminating high pressure resistant electronic energy-saving lamp.
In recent years, ground such as Japan, Hong Kong have the electronic energy-saving lamp listing successively.In China, along with development and national economy, electronic energy-saving lamp also has manufacturer production in part provinces and cities.But apply not extensive.Its main cause is that its high voltage performance is generally relatively poor.Over proof 10%(is 242V when mains fluctuation) time, ballast part transistor very easily is damaged.Show that by inquiry domestic this electron-like electricity-saving lamp all is not provided with excess voltage protection, its reason has three; the one, adopt a series of overvoltage protection measures; make the circuit complexity, cost is too high, and at present external this series products than the high 1-2 of domestic current product price doubly.If overvoltage protection according to said method is set.Be difficult on the price be accepted by the present economic condition of China people.The 2nd, if adopt triode high-power, high back-pressure, situation can improve to some extent, but cost improves too much.The 3rd, adopt the outage overvoltage protection.Circuit complexity not only.Cost is also high, and in case shields.Light extinguishes.Retrieve according to the electronic energy-saving lamp that to the patent No. is 90211376.3.The designer does not also adopt excess voltage protection.As seen adopt the overvoltage protection not a duck soup.But owing to do not adopt this class safeguard measure, only the light fixture that causes owing to the overvoltage factor damages, and its numeral is unexpectedly up to about 20%.The economic loss that this ratio of reprocessing causes is rather considerable.
The purpose of this utility model is that a kind of circuit is simple, the low electric energy-saving light fixture that can play over-voltage protection function again of cost for society provides.
The technical solution of the utility model promptly adds excess voltage protection in the entire circuit system, in general, electronic energy-saving lamp all has the low characteristics of starting voltage (often getting final product build-up of luminance for about 80V), and works under this interval voltage of 80V～150V.The triode of ballast part is not in switch working state.But be in the amplification operating state.The triode power consumption increases.Though starting voltage is low is its characteristics, works unsatisfactoryly under the low-voltage crossing, in view of the above the operating voltage interval range is moved toward high-end, be main body conception plans of the present utility model, it can be in 264V～130V scope long-term stable operation.
