How to choose a high-quality power supply?

LED Power Supplysfyh
1. From the perspective of performance, the dimming power supply must have stable dimming performance. There are many dimming power supplies that are not ideal because they will flicker and become unstable during dimming. When dimming, there may be some noise, which will affect people around. Choosing triac dimming 100W led power supply can solve these problems 2. The production quality of the dimming power supply is very important. If the quality of a device is not good, the natural use effect will not be good, and the service life will be short. The premise of high-quality production quality is…

Dimming analysis of LED dimming power supply

LED Power Supplysfyh
LED dimming is to adjust the current supplied to the LED luminous tube to achieve the purpose of dimming brightness. LED has strict requirements on supply voltage and current, too high voltage and current will seriously reduce its service life. At present, the commonly used LED dimming power supply include: triac dimming, 0-10V dimming power supply, PWM dimming power supply, DALI dimming and DMX dimming. The working principle of dimming is to achieve LED dimming function by controlling the output of current, voltage and frequency. 1. Triac dimming It has been applied to the dimming method of incandescent lamps and…

Choose LED Power Supply or power adapter?

Both LED power supply and power adapter are widely used for driving LED strip light. How to choose the suitable one? Depend on the project scale and installation way. Many users intend to find a led strip driver for 5m or 10m LED strips. Here we have to explain that it is not the LED strip length that determines what led power supply driver to choose, however is the total wattage of the LED strip, we all know LED strip lights are designed with different wattage per meter or per foot. The basic principle is: if you need at most…

The Lifetime and Reliability of led driver vs power supply

LED Power Supplysfyh
The LED is a device that includes a single PN junction and has conductivity on one side. The LED will only emit light when current is applied forward. Because LED lights work at low voltage, the led screen power supply needs to properly manage the load and effectively provide the required low voltage power to the LED. The street light power supply rectifies commercial AC power into DC power, and converts the rectified DC power into DC power of a predetermined magnitude. Usually, the led street light power supply fails before the LED reaches the end of its life, so the…

What problem does the LED power supply need to solve?

LED Power Supplysfyh
In the current lighting market, LED drive power is gradually accepted by people due to its low power consumption, low heat generation, and long lifespan. LED drive has become more and more important in the market. In LED lighting, the most important thing is dimming and thermal balance. How to solve these problems is the problem to be solved by the current LED power supply. With the solution of this problem, the concept of “LED drive” is gradually put forward. For constant current LED drive, it can maintain a constant current within a certain voltage range. This avoids the interference…

The benefits of smart lighting in life

LED Power Supplysfyh
1.Using smart lighting to dimming can maximize energy saving The lighting is artificial lighting, which provides sufficient illuminance at night or occasions with insufficient natural light. But lighting consumes power. When not needed, turning off the lights can save energy. In many public places or buildings, it is not advisable to turn off all the lights at night. The dimming drive power supply can maintain proper lighting, which not only facilitates the convenience and safety of night work or travellers, but also maximizes energy saving. 2.Easy to manage and maintain Intelligent dimming can achieve precise centralized control and unified management…

What Type of LED Driver or Power Supply Do I Need?

LED Power Supplysfyh
There are several different kinds of external dimmable LED drivers, but they can be broken down into two main types in the market: constant current (CC) drivers and constant voltage (CV) drivers. SMARTS manufacture Selectable Multi-current LED drivers from 10w to 60w, current from 100ma to 2100ma costant current power supply, and 6w to 360w led drivers. Depending on the application, LEDs can be connected in series and/or parallel configurations. Obviously, when LEDs are connected in series the forward voltage drop of each LED in the string are additive. For example, if you put 10 LEDs in series and each…

Can you put a 100 watt LED in a 60 Watt fixture?

LED Power Supplysfyh
When it comes to replacing old incandescent bulbs with LEDs, a common question that customers ask is: “Can I use an LED bulb that has a higher wattage equivalent than my fixture allows?” The simple answer is yes, as long as the LED bulb uses less wattage than your fixture. When you see a label say “100Watt LED driver equivalent” that does not mean that the bulb actually uses 100 Watts, it means that it produces an amount of light equivalent to a 100-Watt incandescent bulb. If your socket says not to exceed 60-Watts, it is referring the dangers of…

WHAT does the TA and TC means for your LED driver?

LED Power Supplysfyh
In the electronic component manual, Ta refers to the ambient temperature and Tc refers to the surface temperature of the component. LED driver and power supply are gave the ambient temperature of the driver use and the upper limit of the surface temperature of the outer casing for the user to select the appropriate use environment. click for more information^_^ It is an innate property of the product itself, and it has nothing to do with whether it affects heat dissipation. Can be marked to indicate that the product is managed by quality standards. Hence as a ETL qualified manufacturer,…

What is a Class 2 power supply?

LED Power Supplysfyh
Generally speaking, class 2 standard is for North American market using, class II is for European market using. Both of them are important standard for safety of the power supply and the user. Here I would like to make a brief introduction for the driver power supply with class 2 standard. The class 2 here refers to the power performance and wiring requirements. When you find a power supply with a label marked class 2, then it means that it must meet the standards laid out by The National Electric Code. To avoid risk of shock or fire, the wiring and power…
