Digital Control Technology Dominates LED Public Lighting
Although Led Public lighting(CLASSIC) is popular throughout the industry, it has some limitations in dimming. In fact, ordinary drivers are unable to provide satisfactory dimming performance, energy efficiency and reliability at an appropriate price. In some applications, including homes, restaurants, and the like, smooth and glare-free dimming is required.
The triac integrated dimmer is designed to drive resistive loads. This can also be referred to as a leading edge dimmer, which is generated by delaying the triac.
When the signal of the triac dimmer is given, assuming the current in the normal demand, the dual switch starts running and causes it to operate in the left normal period. However, even for incandescent lamps, two factors can limit the dimming range. Dimming circuits typically include an EMI filter that introduces noise into the inductor and capacitor. If it is a low quality inductor, the noise can cause the current to be lower than required, which can produce glare.
Compare the minimum load current of the minimum load current of the five triac integrated dimmers. The peak display LED driver requires minimal current to ensure proper operation.
A common solution to the above problem is the discharge circuit - it is sufficient to maintain the triac circuit at lower dimming levels. There are two drawbacks to using passive release. The first is the loss of power and the other is about the effect of heat dissipation on life. Thermal management is critical to LED public lighting. LEDs can operate from 25,000 to 50,000 hours. However, some components are more sensitive to operating temperatures. The temperature rises by 10 ° C, and the life of the capacitor will be reduced by 50%.
A satisfactory solution is to recover leakage current instead of heat. It used to be said that it is not easy to complete. At the same time, digital technology can provide a lot of help by intelligently controlling the amount of heat required.
In addition, the IC digital circuit is responsible for the relative voltage and current to achieve dimming as needed. The IC also integrates intelligent functions that allow for free adjustment of the impedance as a dimmer feature, which helps to better adjust for improved efficiency.
Customers always expect better lighting, which requires the industry to upgrade its existing technology. New technologies must be introduced at competitive prices, while at the same time it must improve energy efficiency and reliability. In summary, digital technology in LED public lighting provides better solutions to meet customer expectations.
