With the rapid development of electronic technology, electronic components quality enhances unceasingly, make the electronic ballast is the basic guarantee of reliability, therefore, the current fluorescent lamp, energy-saving lamp lighting circuit has a large number of electronic ballasts are replaced.
To a large number of application on the HID lamp electronic ballasts, must solve the problem of the reliability of the HID lamps with electronic ballasts and its performance/cost ratio.
1, maintain a constant output power: keep the lamp instantaneous output power is constant, such as driven by square wave current available light output characteristic of instantaneous power output constant, ensuring that the acoustic resonance phenomenon does not occur.
2, abnormal protection function: the electronic ballast can appear in with lamp tube leakage, activation, start-up and main circuit current is too large anomalies, such as to make the ballast is not damaged, set the abnormal protection function, the bulb when an exception occurs, shut down automatically ballast, to ensure product performance and reliability.
3, over current, voltage control, power grid harmonic and noise pollution,
Such as instantaneous high pressure, high energy pulse)
, and lightning flow impact will directly affect or damage the switch tube, capacitors, etc. , so you need to set up protection.
4, to reduce the temperature rise, the rise of temperature of the ballast mainly from semiconductor components produced by the power consumption and fever, temperature rise, its life is reduced, the design, try to minimize power consumption, improve efficiency, excellent electronic ballast electrical efficiency over 90%.
The professional electronic insulation filling and sealing glue, can reduce product overall temperature rise, prevent water, dirt and other debris into the short-circuit product damage caused by moisture, further improve the reliability of the product, and also to prevent the transport vibration and impact damage.
Electric light up every inch of space for everyone, we can according to customer requirements and the actual use of the environment, customized products and provide integrated solutions for customers, for the general customers to provide quality and efficient products.
We look forward to cooperate with customers and friends from all over the world hand in hand, create brilliance.
