Many years ago, I entered the field of large-scale application of LED products; LED lighting devices have witnessed a gradual increase in the quality of products, from low to high brightness light intensity, high brightness development.


With the relatively large power and high light efficiency of the devices appear, the product also has a very substantial price decline; that could signal light from the display and to a broader range of applications of general lighting applications market expansion. But also for work in LED applications provide the basis to display their ability.


Then the face of large-scale application of LED traffic lights products has created a concept of thinking: that although there are many limitations of using the LED and shortcomings, it cannot do anything but should carry out its duties. The LED application industry must consider the travel of the existing devices on how to make good use of theirpotential, which requires an in-depth understanding of LED characteristics and good use of the LED.


Constant Current Driversarea current device, light generated by the current efficiency; in the electrical characteristics and the equivalent of a regulator. Theflow of recent changes is caused by changes in voltage across the very small However, suppose the applied voltage exceeds the LED's voltage videos, which areslim prominent, and significant. In that case, the current will be considered through substantial changes, so the LED will be powered by a current source, which requires constant- Voltage power supply and then try to limit resistance in a way which is not a way; LED at work because of fever, aging resulted in pressure drop, and finally to cause pressure changes in the creation or current variation.


People questioned the LED used in unsatisfactory performance or failure rate when the deficiencies of the LED should have an objective attitude, because developing anything, progress needs to have a process, not to mention the LED, has now revealed the great prospect. The energy of the point can be carefully examined, and the device’s operational status and production process can be tested.


Must understand that LED is a delicate device, so applications are always trying to get as much as possible from the LED luminous flux to reduce costs. Current work is often close to the upper limit, but due to power surges, such as induced current overload, even if the short-term accidents are bound to damage the device.Learn more about Constant Current Led Drivers at www.emcod.com.
