A simple understanding of the quality of LED driver

After so many years of experience and contacts with lighting manufacturers, I feel that the lighting manufacturers often do not know how to distinguish good quality driver instead of not willing to buy good quality driver. What’s more, they are also more worried about whether they have spent much money to buy low quality driver. Then how to distinguish the quality of LED driver? We do recognize from the following aspects:

　First, the driver chip — IC

The core of driver is IC, thus the quality of IC determines the quality of driver. Manufacturers of driver IC are looking to buy Crystal Park large packaging factory to package; relatively small factory driver IC technology is a direct copy of the drive manufacturers design packaging factory to find a small package, can not properly protect the entire batch of IC consistency and stability, resulting in the use of drive power failure after a period of time somehow. So IC LED on the power supply, refuse polished to lighting manufacturers to understand the driving IC solutions and accounting costs, so purchasing power products at reasonable prices.

　　Second, the transformer

Power supply control chip can be regarded as the brain center, but the one decides power and temperature resistance, etc. is transformer. Quality of magnetic core is the core of the transformer, but it is difficult to identify as porcelain in general. Easy to distinguish appearance: appear crispy, dense, bright, while the back of the sanding holes for the top grade. Currently the core meaning Heino used to mold the PC44 core to protect high-efficiency power supply.

　　Third, electrolytic capacitors and SMD ceramic capacitors

We may all know the input electrolytic capacitor quality and longevity requirements and we all take very seriously. However, we tend to overlook the quality requirement of the output capacitance. In fact, the output capacitor life has a great impact on the power of life. The output frequency of 60,000 times per second will lead to the parasitic capacitance due to increased heat resistance, a similar scale substance finally electrolyte temperature, the slurry explosive. Recommended output electrolytic capacitors are LED special electrolysis, generally beginning with L models.

Some leading-edge of LED lighting

It is generally believed that it is a great initiative to save 4/5 energy for the energy-saving lamps, but LED lamps save another 1/4 more than energy- saving lamp, which is a greater reform of solid sources. In addition, LED also has other advantages: high quality. It basically has no radiation and is a typical of the green lighting; reliable and durable with very low maintenance costs and so on. Because of the unmatched features that LED light source has over other solid light sources, LED lighting industry will be the main source 10 years later.

LED lighting

The operating voltage of LED is low, mostly 1.4-3V; ordinary LED operating current of only 10mA, high brightness but also the 1A. LED in the production process do not add ” Mercury ” and does not need inflated , no glass shell , impact resistance , shock resistance , unbreakable , easy to transport , very green , known as ” green energy .”

LED is small in size and light in weight. The epoxy resin shell protects not only the chip but also the ability of the transparent condensing. LED life is generally between 50,000-100,000 hours. Since the LED is a semiconductor device, even frequent switching, it will not affect the service life. Currently the mainly used household lightings are incandescent, fluorescent and energy-saving fluorescent lamps.

LED response frequency f Can cystatin bearded mechanic  QI Yong neon Ti  mc related, such as LED GaAs material, which generally within 1-10ns range, frequency response of approximately 16-160MHz, this high the response frequency of 6.5MHz for displaying a video signal is sufficient , and this is one of the key factors of LED large screen video .

Currently, LED has reached the minimum response time of 1 microsecond, more often a few milliseconds, about 1/ 100 of the response time of ordinary light. It can be used in many high-frequency environments, such as automobile brake lights or status lights. You can shorten the time the car brakes of the vehicle, thereby improving safety.
