Looking back from 2011 to 2012, under the shadow of the financial crisis, with the European debt crisis, the downgrading of credit ratings of many countries such as the United States, and rising inflation in emerging markets, the international environment is facing new uncertainties and complexities. As an emerging industry, the LED lighting industry lighting project is not only affected by the global environment, but also has its industry specificity.

  And the LED street lamp 50w led driver is precisely the top priority in the current LED development. There are already a variety of solutions and unique design methods for the related design of LED technology. Let's take a look one by one:

1.Why the street light must use a constant current led driver?

The characteristics of LED lighting materials determine that they are greatly affected by the environment. For example, as the temperature changes, the current of the LED will increase, and the increase of the voltage will increase the current of the LED lamp beads. Long-term work beyond the rated current will greatly shorten the life of the LED lamp beads. And LED constant current is to ensure that its operating current value remains unchanged when environmental factors such as temperature and voltage change. The street lamp power supply developed by our company is generally recognized by the majority of engineering companies and street lamp manufacturers because of its temperature rise and high product stability.

  2. What is the most suitable working current of the LED street lamp 50w led driver?

For example, the rated working current of the LED is 350 mA. Some factories use it up at the beginning. The design is 350 mA. In fact, it is very hot to work under this current. After many comparison tests, it is ideal to design it to 320 mA. . Minimize the amount of heat generated, so that more electrical energy becomes visible light energy.

3. Working voltage of LED street light 50w led driver

The recommended working voltage of general LEDs is 3.0-3.5V. After testing, most of them work at 3.2V, so the 3.2V calculation formula is more reasonable. The total voltage of N lamp beads in series = 3.2* N

4. Constant current accuracy of LED street lamp 50w led driver

The constant current accuracy of some power supplies on the market is poor, and the constant current schemes such as popular recommended schemes on the market have an error of±8%, and the constant current error is too large. The general requirement is within±3%. According to the 3% design plan. The production power must be fine-tuned to achieve±3% error.

        In summary: the current market for LED street 50w led driver still has a certain demand. After all, for municipal construction, these LED street lamps, LED street lamp power supplies, LED flood lights, LED tunnel lights, etc. have a huge market foundation.
